Step-by-step explanation:
The price increased from $0.30 to $2.40. What is the rate of increase, in percentage?
We can use the formula shown below:
[tex]\frac{New-Old}{Old}*100[/tex]
Where
New Price is 2.40 and the Old Price is 0.30
We substitute and calculate:
[tex]\frac{New-Old}{Old}*100\\\frac{2.40-0.30}{0.30}*100\\=7*100\\=700[/tex]
Hence,
Price increased 700%

An insurance company pays its agents 40% commission on the first year’s premium and 5% on the second year’s premium for life insurance policies. If the premiums are 500$ per year, what is the total commission that will be paid during the two years?
Answers
The total commission that will be paid during the two years is $ 225
Solution:
Given that insurance company pays its agents 40% commission on the first year’s premium and 5% on the second year’s premium for life insurance policies
The premiums are 500$ per year
Commission on first year:
40% commission on the first year’s premium
Thus 40 % commission on $ 500
[tex]\rightarrow 40 \% \text{ of } 500\\\\\rightarrow 40 \% \times 500\\\\\rightarrow \frac{40}{100} \times 500\\\\\rightarrow 200[/tex]
Thus commission paid for first year is $ 200
Commission on second year:
5 % commission on the second year’s premium
Thus 5 % commission on 500
[tex]\rightarrow 5 \% \text{ of } 500\\\\\rightarrow 5 \% \times 500\\\\\rightarrow \frac{5}{100} \times 500 = 25[/tex]
Thus commission paid for second year is $ 25
Total commission paid = $ 200 + $ 25 = 225
Thus Total commission paid is $ 225

Answers
Answer:
I'm not Certain but I'm thinking that it would be 4 boxes of the regular tea and 5 of the herbal tea.
Step-by-step explanation:
herbal- $1.50
regular- $1
$1*4 =$4
$1.50*5 = $7.50
$4.00+ $7.50=11.50
Answer:
Herbal tea box = 3
Regular tea box = 7
Step-by-step explanation:
Le x be the number of herbal tea box and y be the number of regular tea box.
The herbal tea variety cost $1.50 per box and the regular variety cost $1.00 per box they bought A total of 10 boxes and spent $11.50.
[tex]x+y=10\Rightarrow y=10-x[/tex] .... (1)
[tex]1.50x+1.00y=11.50[/tex] ... (2)
From (1) and (2) we get
[tex]1.50x+1.00(10-x)=11.50[/tex]
[tex]1.50x+10-1.00x=11.50[/tex]
[tex]0.50x=11.50-10[/tex]
[tex]0.50x=1.50[/tex]
[tex]x=\dfrac{1.50}{0.50}=3[/tex]
Substitute x=3 in equation (1).
[tex]y=10-x=10-3=7[/tex]
Therefore, the number of herbal tea boxes is 3 and the number of regular tea boxes is 7.

Six cars pull up to a red light, one at a time. At the light, there are three lanes, one left-turn lane, one straight-going lane, and one right-turn lane. How many ways can the cars stack up so that all three lanes are occupied? Note that if the first car turns left and the second goes straight, this is considered different from the first car going straight and the second car turning left. In other words, the cars are distinguishable, but pull up to the intersection in a fixed order.
Answers
Answer: [tex]540[/tex]
We count the number of ways that some lane can be left empty, and subtract from the total:
Each driver has three choices, so it's [tex]3^6 = 729[/tex].
Now, we count the ways where at least 1 lane is left empty:
But we have double-counted the situations where two lanes are left empty. Since each driver only has one choice, there are [tex]3(1^6)[/tex] situations we overcount. This leaves [tex]729 - (192 - 3) = 540[/tex] ways to fill all three lanes.

what is the radius of the circle x^2+y^2+21=10x
Answers
Answer:
The radius of the given equation is 2 .
Step-by-step explanation:
The equation of a circle whose center (h, k) and radius is r,
(x - h)² + (y - k)² = r² ..............................(i)
Here given that-
x² + y² + 21 = 10 x
x² - 10 x + y² + 21 = 0
( To making perfect square, add and subtract 25 ) -
x² - 10 x + 25 - 25 + y² + 21 = 0
(x² - 10 x + 25) + y² -4 =0
[As we know that -
(x - 5)² = x² - 10 x + 25]
(x - 5 )² + y² = 4
(x - 5)² + (y - 0)² = 4
(x - 5 )² + (y- 0)² = 2² ................................(ii)
On comparing equation (i) and(ii)-
r = 2
Hence the radius of the given equation is 2 and center is ( 5, 0).

Now, in Δ BCD, G is the midpoint of DB and GF is parallel to CD. {From relation (1)}
So, we can write F is the midpoint of BC. (Proved)
[Since we know the theorem that if we joint the midpoints of two sides of a triangle then the line formed will be parallel to the third side.]
Introduction to the triangle midsegment theorem‼️ can someone help me find BC,DE, and CE please ❓
Answers
Answer:
Part 1) [tex]BC=68\ units[/tex]
Part 2) [tex]DE=36\ units[/tex]
Part 3) [tex]CE=34\ units[/tex]
Step-by-step explanation:
we know that
The Midpoint Theorem states that the segment joining two sides of a triangle at the midpoints of those sides is parallel to the third side and is half the length of the third side
so
Part 1) Find the length of BC
Applying the Midpoint Theorem
[tex]DF=\frac{1}{2}BC[/tex]
we have
[tex]DF=34\ units[/tex]
substitute the given value
[tex]34=\frac{1}{2}BC[/tex]
solve for BC
[tex]BC=34(2)=68\ units[/tex]
Part 2) Find the length of DE
Applying the Midpoint Theorem
[tex]DE=\frac{1}{2}AC[/tex]
we have
[tex]AC=72\ units[/tex]
substitute the given value
[tex]DE=\frac{1}{2}(72)[/tex]
[tex]DE=36\ units[/tex]
Part 3) Find the length of CE
we know that
[tex]BC=CE+BE[/tex] ----> by addition segment postulate
The point E is the midpoint segment BC
That means
[tex]CE=BE[/tex]
so
[tex]BC=2CE[/tex]
we have

Sunil takes 5 more days than Anil to a certain work . Anil left the work after 4days,Sunil takes 5days to complete the rest work . How many days they took to complete the work
Answers
Answer:
Anil would take 10 days and Sunil would take 15 days to complete the work.
Step-by-step Explanation:
To Determine:
How many days they took to complete the work?
Information Fetching and Solution steps:
Sunil takes 5 more days than Anil to a certain workAnil left the work after 4 daysSunil takes 5 days to complete the rest workLet is consider,
The number of days taken by Anil to complete the required work = d.
The number of days taken by Sunil to complete the required work = d + 5
Work done by Anil in one day = 1÷d
Work done by Sunil in one day = 1÷ (d+5)
Work done together by Anil and Sunil for one day = 1/d + 1/(d+5)
= (d+5+d)/d(d+5)
= (2d+5)/d(d+5)
Work done together by Anil and Sunil for 4 days = 4×(2d+5)/d(d+5) ....[A]
Work done by Sunil in 5 days = 5÷ (d+5) ....[B]
By adding equation [A] and [B], we can determine the complete work
[A] + [B] = 1
((4×(2d+5)/d(d+5))) + (5÷ (d+5)) = 1
8d+20+5d=1d(d+5)
13d+20=d²+5d
−d²+8x+20=0
(−d−2)(d−10)=0
d=−2 or d=10
As number of days can not be negative. So, d = 10. Therefore,
The number of days taken by Anil to complete
the required work = 10 days
The number of days taken by Sunil to complete
the required work = d+5 = 15 days
Hence, Anil would take 10 days and Sunil would take 15 days to complete the work.

identical vacation houses, equally spaced along a street, are number consecutively beginning with 10. maria lives in house #17. joshua lives 4 houses away from maria. what are possible numbers for joshua's house?
Answers
Answer:
Possible numbers for Joshua's house are #13 and #21.
Step-by-step explanation:
Given:
Vacation houses are equally spaced along a street.
The first house is marked with #10 and so on.
Maria lives in house marked as #17.
Joshua lives 4 houses away from Maria.
So, the difference between Joshua's house number and Maria's house number is 4.
Let 'x' be the house number of Joshua's house.
Case 1: If Joshua's house is after Maria's house. So, [tex]x> 17[/tex]
[tex]x-17=4\\x=17+4=21[/tex]
Case 2: If Joshua's house is before Maria's house. So, [tex]x<17[/tex]
[tex]17-x=4\\17-4=x\\13=x\ or\\x=13[/tex]
Therefore, the possible numbers for Joshua's house are #13 and #21.
A spinner with the colors orange, yellow, purple, and green is spun. What is the theoretical probability, as a decimal, of stopping on the color purple? Round the decimal to the nearest hundredth.
Answers
Answer:
Step-by-step explanation:
a spinner with the colors orange, yellow, purple, and green.....so this spinner only has 4 spaces....and 1 of those spaces is purple...so the ratio of stopping on purple is 1/4 or 0.25
The spinner has 4 colors, and purple is one of these. To find the theoretical probability of it stopping at purple, we divide 1 by 4, resulting in 0.25. Therefore, the theoretical probability of the spinner stopping on purple rounded to nearest hundredth is 0.25.
Explanation:The probability of the spinner stopping on the color purple can be calculated by dividing the number of ways this can happen (which is 1, as there's only one purple on the spinner) by the total number of outcomes in the sample space (which is 4, as there are 4 colors on the spinner).
So, the probability would be 1 ÷ 4 = 0.25.
To get the value as a rounded decimal to the nearest hundredth, it stays 0.25 as it is already to the nearest hundredth.

A typical marathon is 26.2 miles. Allan averages 12 kilometers per 1 hour when running in marathons. How long does it take for Allan to complete a marathon, to the nearest tenth of an hour.
Answers
Answer:
3.5 hours
Step-by-step explanation:
Given: Distance= 26.2 miles
Speed= 12 km/h
First lets convert the unit of speed from kmh to mph.
Remember, 1 mile= 1.609 km
∴ For speed of 12 km/h= [tex]\frac{12}{1.609}= 7.45\ mph[/tex]
Speed= 7.45 mph
Next, find time taken by Allan to complete a Marathon.
[tex]Time= \frac{Distance}{speed}[/tex]
⇒ Time= [tex]\frac{26.2}{7.45}[/tex]
∴ Time= 3.516 hours ≅ 3.5 h (nearest tenth)
∴ Allan took 3.5 hours to complete marathon.
Allan takes approximately 3.5 hours to complete a marathon. This is determined by converting the marathon distance to kilometers and dividing it by his running speed.
To determine how long it takes Allan to complete a marathon, we need to convert the marathon distance from miles to kilometers and then find the time it takes based on his running speed.
1 mile is approximately 1.60934 kilometers, so:
26.2 miles × 1.60934 km/mile ≈ 42.164 km
Allan runs at an average speed of 12 kilometers per hour. The time (t) needed to complete the marathon can be calculated as:
t = distance / speed
t ≈ 42.164 km / 12 km/h ≈ 3.514 hours
Rounding to the nearest tenth of an hour, Allan takes approximately 3.5 hours to complete the marathon.

Question: Find The Sum Of The Integers From -6 To 58 Of Ss. O 1,500 O 1,734 O 1,690 O 1,621
Answers
Answer:
The Sum Of The Integers From -6 To 58 is 1690.
Step-by-step explanation:
Given,
[tex]a=-6[/tex]
[tex]T_n=58[/tex]
We have to find out the sum of integers from -6 To 58.
Firstly we will find out the total number of terms that is 'n'.
Here [tex]a_1=-6\ and\ a_2=-5[/tex]
[tex]\therefore d=a_2-a_1=-5-(-6)=-5+6=1[/tex]
Now we use the formula of A.P.
[tex]T_n=a+(n-1)d[/tex]
On substituting the values, we get;
[tex]58=-6+(n-1)1\\\\n-1=58+6\\\\n-1=64\\\\n=64+1=65[/tex]
So there are 65 terms in between -6 To 58.
That means we have to find the sum of 65 terms in between -6 To 58.
Now we use the formula of Sum of n_terms.
[tex]S_n=\frac{n}{2}(2a-(n-1)d)[/tex]
On substituting the values, we get;
[tex]S_{65}=\frac{65}{2}(2\times-6+(65-1)1)\\\\S_{65}=\frac{65}{2}(-12+64)\\\\S_{65}=\frac{65}{2}\times52\\\\S_{65}=65\times26=1690[/tex]
Hence The Sum Of The Integers From -6 To 58 is 1690.
Final answer:
The sum of the integers from -6 to 58 is calculated using the formula for the sum of an arithmetic series and is found to be 1,690.
Explanation:
To find the sum of the integers from -6 to 58, we can use the formula for the sum of an arithmetic series, which is S = n/2 * (a1 + an), where S is the sum of the series, n is the number of terms, a1 is the first term, and an is the last term.
We first need to determine the number of terms in our series. Since our series starts at -6 and ends at 58, we can find the number of terms by subtracting -6 from 58 and then adding 1 (because both ends are inclusive). That gives us 58 - (-6) + 1 = 65 terms.
Now, we can plug the values into the sum formula:
S = 65/2 * (-6 + 58) = 32.5 * 52 = 1690.
Therefore, the sum of the integers from -6 to 58 is 1,690.

A baseball team played 32 games and lost 8 Katy was the catcher in 5/8 of the winning games and 1/4 of the losing games
Answers
Answer:
a. Fraction of games won by team is [tex]\frac{3}{4}[/tex].
b. Total games played by Katy as catcher is 17.
Step-by-step explanation:
Here is the complete question: A baseball team played 32 games and lost 8 Katy was the catcher in 5/8 of the winning games and 1/4 of the losing games.
a. What fraction of the games did the team win?
b. In how many games did Katy play catcher?
Given: Total number of games= 32
Total games lost= 8.
Katy was the catcher in 5/8 of the winning games.
Katy was the catcher in 1/4 of the losing games.
Now, finding total number games that team won.
Winning total= [tex]32-8= 24[/tex]
∴ Total number of games that team won is 24.
Next finding fraction of the games did the team win.
Fraction of games won by team is [tex]\frac{Games\ won}{Total\ number\ of\ games}[/tex]
∴ Fraction of games won by team = [tex]\frac{24}{32} = \frac{3}{4}[/tex]
Fraction of games won by team is [tex]\frac{3}{4}[/tex]
Lets find out numbers of games Katy play chatcher.
We know, Katy was the catcher in 5/8 of the winning games.
∴ Katy was catcher= [tex]\frac{5}{8} \times 24= 5\times 3[/tex]
Katy was catcher in 15 of the wining games.
We also know, Katy was the catcher in 1/4 of the losing games.
∴ Katy was catcher= [tex]\frac{1}{4} \times 8= 1\times 2[/tex]
Katy was the catcher in 2 of the losing games.
Total games played by Katy as catcher= Catcher in wining games+ catcher in losing games.
∴ Total games played by Katy as catcher= [tex]15+2= 17 games.[/tex]
Hence, total games played by Katy as catcher is 17.
Two cars travel at the same speed to different destinations. Car A reaches its destination in 15 minutes. Car B reaches its destination in 35 minutes. Car B travels 15 miles farther than Car A. How fast do the cars travel? Write your answer as a fraction in simplest form.
Answers
Answer:
The cars are travelling ar the speed 45 mph.
Step-by-step explanation:
Let the two cars are moving at the speed of x mph.
Now, Car A reaches its destination in 15 minutes i.e. [tex]\frac{15}{60} = 0.25[/tex] hours.
Therefore, Car A travels in 15 minutes by 0.25x miles.
Again, Car B reaches its destination in 35 minutes i.e. [tex]\frac{35}{60} = 0.583[/tex] hours.
Therefore, Car B travels in 35 minutes by 0.583x miles.
Given that, (0.583x - 0.25x) = 15
⇒ 0.333x = 15
⇒ x = 45 mph
Therefore, the cars are travelling ar the speed 45 mph. (Answer)
The cars travel at a speed of 3/4 miles per minute.
Explanation:To find the speed of the cars, we can use the formula Speed = Distance/Time. Let's assume that Car A's speed is x miles per minute. Since Car B travels 15 miles farther than Car A and takes 35 minutes to reach its destination, Car B's speed would also be x miles per minute. Now, using the given information, we can set up two equations:
x * 15 = x * 35 - 15
Simplifying the equation, we get:
15x = 35x - 15
20x = 15
x = 0.75
Therefore, the cars travel at a speed of 0.75 miles per minute or the fraction 3/4 miles per minute.
