The rule at Anna's house is that if she eats all of her vegetables and does all of her does each day, she earns 2 hours of Internet time which she can save. Anna started her week with 3 hours saved. If she eats all of her vegetables and does all of her chores each day for 4 days straight how many hours does she have after the four days she uses 6 hours of her internet time
Answer:
5 Hours
Step-by-step explanation:
Given :- 2 hours can be earned each day if she eats all of her vegetables and does all of her chores.
Saved hours at the start of the week = 3 hours
Hours earned in 4 days = 2 hours × 4
= 8 hours
Hours used in 4 days = 6 hours
Hours left after 4 days = Saved hours at the start of the week + Hours earned in 4 days - Hours used in 4 days
Hours left after 4 days = 3 + 8 - 6
= 5 hours
The height y (in feet) of a toss in bocce ball can be modeled by y=-x^2+4x, where x is the horizontal distance (in feet)
Interpret the x-intercepts of the graph of the equation.
How far does the bocce ball land on the ground?
The x-intercepts of the equation represent the points where the height of the toss is equal to 0. The bocce ball lands on the ground at a horizontal distance of 0 feet and 4 feet.
Explanation:The x-intercepts of the graph of the equation represent the points where the height of the toss is equal to 0.
In other words, these points represent the horizontal distance where the bocce ball lands on the ground.
o find the x-intercepts, we set y=0 and solve the equation:
0=-x^2+4x
x(x-4)=0
Therefore, the x-intercepts are x=0 and x=4.
This means that the bocce ball lands on the ground at a horizontal distance of 0 feet and 4 feet.
bryan says all prime numbers are odd numbers list all the prime numbers less than 20 in a numerical order
Prime numbers less than 20 in numerical order are 2, 3, 5, 7, 11, 13, 17, and 19. Note that 2 is the only even prime number.
Explanation:Bryan's statement that all prime numbers are odd numbers is not entirely correct. By definition, prime numbers are numbers that have only two distinct positive divisors: 1 and the number itself. Therefore, the number 2 is considered a prime number, despite being even. Listing all the prime numbers less than 20, we have:

A hybrid car can travel 40 miles per gallon. Approximately how many gallons of fuel will the car need to travel 20 km? [1 mile = 1.6 km]
A. 0.3
B. 0.8
C. 2.5
D. 3.2
Answer: The car would need 0.3 gallons of fuel to travel 20km.
Step-by-step explanation: 40mile x 1.6km = 64km
1 gallon 1 mile 1 gallon
20km ÷ 64km = 0.3125
Answer:
In 0.3 gallon of fuel, the car will travel 20 km.
A is the correct option.
Step-by-step explanation:
We have been given that in 1 gallon of fuel the car can travel 40 miles.
Now, 1 mile = 1.6 km.
Hence, in 1 gallon the car travel 40×1.6 = 64 km
Let the car will consume x gallons of fuel to travel 20 km.
Thus, we have the equation
[tex]\frac{1}{64}=\frac{x}{20}[/tex]
ON solving for x
[tex]x=\frac{20}{64}\\\\x=0.3[/tex]
Therefore, in 0.3 gallon of fuel, the car will travel 20 km.
A is the correct option.
I bought 4 hamburgers and 3 fries for $14.25 and the next day I bought 3 hamburgers and 5 fries for $15.50 find out the price for each hamburger and fry
Answer:
The cost of a hamburger is 2.25
The cost of fries is 1.75
Step-by-step explanation:
Let h = cost of hamburgers
let f= cost of fries
4h + 3f = 14.25
3h+5f = 15.50
I will solve these by elimination
Multiply the 1st equation by 3
3(4h + 3f )= (14.25)3
12h +9f = 42.75
Multiply the 2nd equation by -4
-4(3h+5f )= -4(15.50)
-12h - 20f = -62
Add the modified equations together
12h +9f = 42.75
-12h - 20f = -62
----------------------------
-11 f = -19.25
Divide each side by -11
-11f/-11 = -19.25/-11
f = 1.75
Now we need to find the cost of the hamburger
3h+5f = 15.50
Substitute the cost of the fries in
3h + 5(1.75) = 15.50
3h +8.75 + 15.50
Subtract 8.75 from each side
3h = 15.5-8.75
3h =6.75
Divide by 3
3h/3 =6.75/3
h = 2.25
Amanda is riding her bicycle. She takes 5 hours to ride 62.5 kilometers. What is her speed?
Answer:
12.5 per kilometers
Step-by-step explanation:
to find speed is going to be distance divided by time so 62.5/5
so her speed is going to be 12.5
Amanda's average speed while riding her bicycle is found by dividing the total distance of 62.5 kilometers by the total time of 5 hours, resulting in an average speed of 12.5 kilometers per hour.
To calculate her speed, we use the formula for speed, which is speed = distance ÷ time. Applying the given values, we have speed = 62.5 kilometers ÷ 5 hours.
Therefore, Amanda's average speed is 12.5 kilometers per hour. This calculation involves dividing the total distance traveled by the total time taken, resulting in the average speed over the journey.
simplify (-6a5b4c3)(5a3b2c)
[tex]\text{Use:}\\\\a^n\cdot a^m=a^{n+m}\\\\(-6a^5b^4c^3)(5a^3b^2c)\\\\=(-6\cdot5)(a^5a^3)(b^4b^2)(c^3c^1)\\\\=-30a^{5+3}b^{4+2}c^{3+1}\\\\=\boxed{-30a^8b^6c^4}[/tex]
Regal Cinemas is selling tickets for the movie “Ghostbusters”. Tomorrow night , there are 73 tickets left to sell. If all the tickets are sold for the same price , the movie theater will make $438. Which of the following students have enough money to buy a ticket?
a. Amanda has $4.50.
b. Bernie has $7.00.
c. Chrissy has $6.50.
d. Dina has $6.00.
e. Evan has $5.00.
f. Frank has $14.00.
Who has enough money to go to the movie? ( write names below )
Answer:
Bernie, Chrissy, Dina and Frank
Step-by-step explanation:
if all 73 tickers are sold, the theatre makes $438 so each ticket is worth $438/73
this equals to $6.00 for one ticket
this means that Bernie, Chrissy, Dina and Frank have enough money to see the movie
Answer:
Bernie, Chrissy, Dina, and Frank are able to go.
Step-by-step explanation:
The question is not entirely clear. I take it that 73 tickets will bring in 438 dollars. If that is so, each ticket is selling for the solution of this proportion.
x / 1 = 438/73 Just do the division on the right
x = 6.00 dollars.
So Amanda will not be able to go.
Even will not be able to go.
Everyone else can.

15 people received an email and sent it to 3 different friends each, who in turn sent it to 2 new people. What percent of the total number of people who received the email are in the original 15 people?
The 10% of people who received the email are in the original 15 people.
What is percent?A number or ratio that can be expressed as a fraction of 100 is called a percentage. Divide the number by its whole number and multiply it by 100 if we have to figure out the percentage of that number. Consequently, the percentage represents one part per hundred. The word "per 100" means "per percent." The number "%" is used to symbolize it.
Given email received by people = 15
sent to 3 different people
the number of people have email = 15 x 3 = 45
then 45 people send it to 2 new
number of people email have = 45 x 2 = 90
total number of person who have email = 15 + 45 + 90 = 150
To the percent of 15 people in a group of 150 people by diving 15 by 150
15/150(100) = 10%
Hence people who received the email are in original 15 is 10%.

What is the relationship between 0.8 ÷ 10^2 and 0.8×10^2
[tex]0.8\times10^2\ \text{is 10,000 times greater than}\ 0.8\div10^2\\\\\dfrac{0.8\times10^2}{0.8\div10^2}=\dfrac{10^2}{1\div10^2}=\dfrac{10^2}{\frac{1}{10^2}}=10^2\times10^2=10^4=10,000[/tex]
Dividing 0.8 by 10² moves the decimal two places to the left, resulting in 0.008. Multiplying 0.8 by 10² moves the decimal two places to the right, resulting in 80. Thus, the two operations produce different magnitudes of the original number.
Understanding the Relationship Between 0.8 ÷ 10² and 0.8 × 10²:
In mathematics, it's essential to understand how operations involving powers of ten affect numbers. Let’s break down the operations:
0.8 ÷ 10²: When you divide a number by 10 raised to the power of 2 (which is 100), you move the decimal point two places to the left. So, 0.8 ÷ 100 = 0.008.
0.8 × 10²: When you multiply a number by 10 raised to the power of 2, you move the decimal point two places to the right. So, 0.8 × 100 = 80.
We can conclude that 0.8 ÷ 10² results in moving the decimal to the left, making the number smaller (0.008), while 0.8 × 10² results in moving the decimal to the right, making the number larger (80).

what is the inverse of the function x + 2y + 3 = 0
The inverse of the function x + 2y + 3 = 0 is found by first expressing the function explicitly as y = -½x - 1½ and then swapping x and y to solve for the new y, yielding the inverse function y = -2x - 3.
Explanation:To find the inverse of a function, we typically swap the roles of x and y, and then solve for y. Given the function x + 2y + 3 = 0, we first write the function explicitly as y in terms of x:
y = -½x - ³2
Now let's find the inverse:
Swap x and y to get x = -½y - ³2.Solve for y. Multiply every term by 2 to get rid of the fraction: 2x = -y - 3.Rearrange the equation to solve for y: y = -2x - 3.This new function y = -2x - 3 is the inverse of the original function.

Answer:
x=12 makes (X-12)/(x-8) equal to zero
x=8 makes (X-12)/(x-8) undefined
Step-by-step explanation:
(x-12)/(x-8) = 0
The first step is to multiply each side by x-8
(x-8) *(x-12)/(x-8) = 0 * (x-8)
This cancels the denominator. x≠ 8 because the denominator would equal 0 and then it becomes undefined.

F: how much money will Jason have in the bank after 9 weeks
G: if Jason has $80 left, how many weeks have passed
This is for question 2 in the picture
Answer:
F $185
G 12 weeks
Step-by-step explanation:
Assuming your equation is correct
y = -35x +500
We want to let x=9
y = -35(9) +500
y = -315+500
y =185
Jason will have $185 after 9 weeks
If he has 80 dollars left we put that in for y and solve for x
80 = -35x +500
Subtract 500 from each side
80-500 = -35x +500-500
-420 = -35x
Divide each side by -35
-420/-35 = -35x/-35
12 = x
After 12 weeks he will have 80 dollars left
which equation describes the line which passes through the points (0. 17, 0) and (0, 0.51)
The equation of the line passing through the points (0, 17) and (0, 0.51) is x = 0.
Explanation:The equation of the line that passes through the points (0, 17) and (0, 0.51) can be found using the slope-intercept form of a linear equation, which is y = mx + b. To find the slope (m), we use the formula (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are the coordinates of the two points.
Substituting the given points, we get m = (0.51 - 17) / (0 - 0) = -16.49 / 0, which is undefined.Since the slope is undefined, we cannot write the equation in the slope-intercept form.However, we can write the equation as x = 0, since the line passes through the x-coordinate of both points.
