Answer:
420cal = 2 cups
Step-by-step explanation:
140cal = 2/3 cup
xcal= 2 cups
Divide 2/(2/3) = 3
Multiply both sides by 3 (answer)
140cal= 2/3 cups (3)
420cal = 2 cups
The 2 cups Contain 420 Cal.
What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
2/3 Cup contain = 140 Cal
So, 1 cup contain = 140 ÷ ( 2/3)
= 140 x 3/2
= 70 x 3
= 210
Then, In 2 cups = 210 x 2
= 420 Cal
Hence, 2 cups Contain 420 Cal.

Step-by-step explanation:
7x is a secant- secant angle and has measure equal to half the difference of the intercepted arcs, that is
7x = 0.5(22x + 10 - 50)
7x = 0.5(22x - 40) ← distribute
7x = 11x - 20 ( subtract 11x from both sides )
- 4x = - 20 ( divide both sides by - 4 )

I can not figure this question out! Plz help!! A drill team is raising money by holding a car wash. The team earns $6.00 for each car washed. The team's expenses include $50.00 for advertising plus $0.50 in materials for each car washed. Let f(x) represent the team's total earnings for washing x cars and g(x) represents the team's total expenses for washing x cars. Describe how you can use f(x) and g(x) to obtain a function p(x) that gives the team's profit for washing x cars. Then write a rule for p(x).
Answer:
Step-by-step explanation:
Total earnings = f(x) = 6x
Total expenses =g(x) = 0.5x + 50
Profit p(x) = f(x) - g(x)
= 6x - ( 0.5x + 50)
= 6x - 0.5x - 50 = 5.5x - 50

Brook rode her bike 7 miles in 30 minutes. Joshua rode his bike 25 miles in 2 hours. which one is faster. HEEEEEEELLLLLLLLLLLLLLPPPPPPPPP
Answer:
Brook is faster.
Step-by-step explanation:
1 hour=60 minutes
2 hours=2*60=120 minutes
-------------
7 miles in 30 minutes vs 25 miles in 120 minutes
7/30=0.233...mile per minute
25/120=0.20833...mile per minute
Brook is faster than Joshua.
Explanation:To determine which person is faster, we can compare their average speeds.
Average speed is calculated by dividing the total distance traveled by the total time taken.
For Brook, she traveled 7 miles in 30 minutes, so her average speed is:
7 miles ÷ 30 minutes = 0.2333 miles per minute.
For Joshua, he traveled 25 miles in 2 hours, which is equivalent to 120 minutes. So his average speed is:
25 miles ÷ 120 minutes = 0.2083 miles per minute.
Therefore, Brook is faster than Joshua as her average speed is higher.

indicates how much profit she makes on a load of tomatoes if she sells them for 4- x dollars
per kilogram
What should Ms.Ortiz charge per kilogram of tomatoes to make the maximum profit, and what is the maximum profit she can make on a loaf of tomatoes
A. $230 at $3 per kilogram
B. $310 at $2 per kilogram
C. $320 at $2 per kilogram
D. $320 at $3 per kilogram
Answer:
The correct answer is B. $310 at $2 per kilogram
Step-by-step explanation:
1. Let's find out the maximum profit Ms. Ortiz can make with a loaf of tomatoes:
function p(x)=–80x² + 320x – 10
For x = 1, price per kilogram of tomatoes would be: 4 - x = 3
–80x² + 320x – 10, replacing with x = 1
-80 * 1² + 320 * 1 - 10 = -80 + 320 - 10 = 230
For x = 2 price per kilogram of tomatoes would be: 4 - x = 2
–80x² + 320x – 10, replacing with x = 2
-80 * 2² + 320 * 2 - 10 = -320 + 640 - 10 = 310
For x = 3, price per kilogram of tomatoes would be: 4 - x = 1
–80x² + 320x – 10, replacing with x = 3
-80 * 3² + 320 * 3 - 10 = -720 + 960 - 10 = 230
The correct answer is B. $310 at $2 per kilogram
Answer:The correct answer is B.) $310 at $2 per kilogram

Step-by-step explanation:
Start by determining the ratio of yellow to red paint. Use the column where both amounts are given:
yellow to red = 2 to 6 = 1 to 3
2 to 6 the same as 1 to 3 when reduced, by dividing both sides by 2.
This means yellow paint is a third of red paint. Backwards, red paint is three times yellow paint.
To go from yellow to red, do yellow X 3.
To go from red to yellow, do red ÷ 3.
Column 1:
1 X 3 = 3
Column 3:
10 X 3 = 30
Column 4:
60 ÷ 3 = 20
The ratios are:
1 to 3
2 to 6
10 to 30
20 to 60
A student is trying to solve the system of two equations given below:
Equation P: y + z = 6
Equation Q: 3y + 4z = 1
Which of the following is a possible step used in eliminating the y-term?
(y + z = 6) ⋅ 4
(3y + 4z = 1) ⋅ 4
(y + z = 6) ⋅ −3
(3y + 4z = 1) ⋅ 3
Answer:
(y+z=6)*-3
Step-by-step explanation:
using this would make the top equation or (y+z=6) turn negative and would be this [-3y-3z=-18) using the distributive property. Since the bottom equation has a positive 3y. The -3y from the top equation and 3y from the bottom ones cancel out leaving you with z=-17 when combining like terms.
Answer:
c is the answer since you are trying to make the ys number (-/+) of the value the other y contains
(3) so you will multiply the first equation by -3 to be able to eliminate y
a store sells packages of comic books with a poster.
1 poster + 6 comics = $12.75
Or

a. write a linear function in the form y=mx+b that represents the cost, y, of a package containing any number of comic books.
b. Construct Arguments. Suppose another store sells a similar package, modeled by a linear function with initial value $7.99 which store has the better deal? Explain.
Answer:
a) [tex]y=m+6.75[/tex] where [tex]m[/tex] is the number of comic books
b) Case B has better deal
Step-by-step explanation:
a)
Let the cost of a poster be [tex]b[/tex] ;Let the cost of a comic book be [tex]x[/tex];Let the number of comic books be [tex]m[/tex];Let the total cost be [tex]y[/tex];Thus, this is in the form of :
[tex]y=m*x+b[/tex]
Given :
[tex]12.75=6*x+b[/tex][tex]19.75=13*x+b[/tex]subtracting both ,
[tex]7=7x\\x=1;[/tex]The cost of one comic book is $1;
substituting in the first equation ,
[tex]12.75=6+b\\b=6.75;[/tex]
The equation is :
[tex]y=m+6.75[/tex]
b)
Since the shop sells poster with a comic book , initial value is the cost of one comic book plus one poster.
[tex]7.99=x+b\\x=1;[/tex] --since its similar.
In case of a. , The cost of one book plus poster = $1+6.75=$7.75
which is lesser than $7.99 .
Thus case B has the best deal.

daniel bought hamburgers and fries for his classmates. the hamburgers costed 1.49 each and a bag of fries cost 1.19. ben spent a total of 50.93. the number of hamburgers was five less than twice the amount of fries, how many hamburgers and fries did he buy
Number of hamburgers bought is 23 and number of bags of fries bought is 14
Solution:Let "h" be the number of hamburgers bought
Let "f" be the number of bags of fries bought
Cost of one hamburger = $ 1.49
Cost of one bag of fries = $ 1.19
Given that Ben spent a total of 50.93
Thus we can frame a equation as:
number of hamburgers bought x Cost of one hamburger + number of bags of fries bought x Cost of one bag of fries = $ 50.93
[tex]h \times 1.49 + f \times 1.19 = 50.93[/tex]
1.49h + 1.19f = 50.93 ------ eqn 1
Also given that the number of hamburgers was five less than twice the amount of fries
number of hamburgers bought = 2(number of fries) - 5
h = 2f - 5 ---------- eqn 2
Let us solve eqn 1 and eqn 2 to find values of "h" and "f"
Substitute eqn 2 in eqn 1
1.49(2f - 5) + 1.19f = 50.93
2.98f - 7.45 + 1.19f = 50.93
4.17f = 50.93 + 7.45
4.17f = 58.38
[tex]f = \frac{58.38}{4.17}[/tex]
f = 14Substitute f = 14 in eqn 2
h = 2(14) - 5
h = 28 - 5 = 23
h = 23Summarizing the results:
number of hamburgers bought = h = 23
number of bags of fries bought = f = 14
Raise the fraction to the highest term 1/5 to 15ths=
Final answer:
To raise the fraction 1/5 to 15ths, multiply both the numerator and the denominator by 3 to get the equivalent fraction 3/15.
Explanation:
To raise the fraction 1/5 to 15ths, we need to find an equivalent fraction that has a denominator of 15. To do this, we need to find a number that we can multiply both the numerator and the denominator of 1/5 by to get a new fraction with a denominator of 15. Since 5 multiplied by 3 equals 15, we multiply both the numerator and the denominator of 1/5 by 3.
Thus, we have:
1/5 × 3/3 = 3/15
To raise the fraction 1/5 to 15ths, multiply both the numerator and the denominator by 3 to get the equivalent fraction 3/15.
The fraction 1/5 is equivalent to 3/15 when raised to 15ths.
A truck carries apples, grapes, and blackberries in the ratio of 4:3:4 if the apple weighs 160 pounds how much does the truckload of fruit weigh in total
Answer:
160/x = 4/3
x = (160/4)(3) = 40(3) = 120
Apples: 160 pounds
Grapes: 120 pounds
Blackberries: 160 pounds
The total weight of this truckload of fruit is 160 + 120 + 160 = 440 pounds.
To find the total weight of the truckload of fruit with apples weighing 160 pounds in a ratio of 4:3:4, calculate the total ratio parts and apply it to the weight of apples. The total weight of the fruit is 440 pounds.
Explanation:The truck carries apples, grapes, and blackberries in the ratio of 4:3:4.
To find the total weight, you need to calculate the total ratio parts, which is 4 + 3 + 4 = 11 parts. Then, for apples alone, 4 parts represent 160 pounds, so each part is 160/4 = 40 pounds. The total weight of the truckload of fruit would be 11 parts * 40 pounds = 440 pounds.

A square has an area of 44.89 inches squared. How do I get the length of the diagonal?
Answer:
6.7√2 in ≈ 9.48 in
Step-by-step explanation:
First, use the area of the square to find the side length.
A = s²
44.89 in² = s²
s = 6.7 in
The diagonal of a square divides it into 45-45-90 triangles. You can use Pythagorean theorem to find the length of the diagonal.
c² = a² + b²
c² = (6.7 in)² + (6.7 in)²
c = 6.7√2 in
c ≈ 9.48 in
Answer: 6.7√2
Step-by-step explanation: Let's start this problem by drawing a picture of a square with a diagonal of length x.
Now to find the length of the diagonal, let's first find the length of a side of the square. To find the length of a side, remember that the formula for the area of a square is S² and since we know that the area of the given square is 44.89 inches, we can set up the equation 44.89 = S².
Square rooting both sides, we have 6.7 = S so we can give the side of our square a length of 6.7. Now to find the value of x, it's important to understand that the diagonal of a square creates 45° 45° 90° triangles and in a 45° 45° 90° triangle, the hypotenuse = √2 × leg.
So we have x = 6.7√2.
So the length of the diagonal of the square is 6.7√2 inches.

While in Europe, if you drive 117 km per day, how much money would you spend on gas in one week if gas costs 1.10 euros per liter and your car's gas mileage is 42.0 mi/gal ? Assume that 1euro=1.26dollars.
Answer:
Total Cost of Week = 81.20 Euros
Total Cost of Week (in dollars) = $102.31
Step-by-step explanation:
117 km per day
You drive 7 days
So,
Total miles driven = 117 * 7 = 819 km
Mileage is 42 miles per gallon. So how many gallons would it require to drive 819 km?
819/42 = 19.5 gallons
We know 1 gallons = 3.78 liters
So,
19.5 gallons would be:
19.5 * 3.78 = 73.82 liters
1.10 Euro PER LITER, so the total cost:
Total Cost of Week = 73.82 * 1.10 = 81.20 Euros
In dollars (1 euro = 1.26 dollars):
Total Cost of Week (in dollars) = 81.20 * 1.26 = $102.31
The cost on gas is approximately 7.2 euros
Data given;
Distance = 117kmrate of consumption = 42.0 mi/galcost of gas = 1.10 eurosConversion of distance from km to milesIf 1mi = 1.609km
And we cover 117km daily, let's convert this into miles
[tex]1mi=1.62km\\ x mi = 117km\\ x = 117/1.62\\ x = 72.2mi[/tex]
This shows that we cover a distance of 72.2 miles daily.
But the car consumes 1 gallon in 42 miles, let's calculate the gas required to cover 72.2 miles
[tex]42mi = 1g\\ 72.2mi =x\\ x = 72.2/42\\ x = 1.719[/tex]
The total gas consumed daily is approximately 1.72 gallons.
Cost of gas dailyThe cost of gas daily can be calculated from the data given but we have to convert the volume from gallon to liter
Gallon - Liter1L = 0.26 gallon
xL = 1.72 gallons
cross multiply this and solve for x
[tex]x = \frac{1*1.72}{0.26}\\ x = 6.6[/tex]
This shows that we consume 6.6L daily.
But we were given that the cost of 1 liter of gas is equal to 1.10 euros
1L = 1.10 euros
6.6L = x euros
[tex]x = \frac{1.1*6.6}{1}\\ x = 7.26[/tex]
The cost of gas daily is 7.26 euros or approximately 7.2 euros.

The question doesn't require any specific probabilities, but I'm adding my own calculations to make it easier for you to solve your own problem
Answer:
Questions added and answered below
Step-by-step explanation:
Venn Diagram
When we have different sets, some of them belong only to one set, some belong to more than one, some don't belong to any of them. This situation can be graphically represented by the Venn Diagrams.
Let's analyze the data presented in the problem and fill up the numbers into our Venn Diagram. First, we must use the most relevant data: there are 60 people in both the choir and the band. This number must be in the common space between both sets in the diagram (center zone, purple).
We know there are 110 people in the choir, 60 of which were already placed in the intersection zone, so we must place 110-60=50 people into the blue zone, belonging to C but not to B.
We are also told that 240 people are in a band, 60 of which were already placed in the intersection zone, so we must place 240-60=180 people into the red zone, belonging to B but not to C.
Finally, we add the elements in all three zones to get all the people who are in the choir or in the band, and we get 50+60+180=290. Since we have 450 people in the school, there are 450-290=160 people who are not in the choir nor in the band.
The question doesn't ask for a particular probability, so I'm filling up that gap with some interesting probability calculations like

The answer is calculated as
[tex]\displaystyle P(A)=\frac{180}{450}=0.4[/tex]
b) What is the probability of randomly selecting one person who belongs only to one group?
We look for people who are in only one of the sets, they are 50+180=230 people, so the probability is
[tex]\displaystyle P(B)=\frac{230}{450}=0.51[/tex]
b) What is the probability of selecting at random one person who doesn't belong to the choir?
We must add the number of people outside of the set C, that is 180+160=340
[tex]\displaystyle P(C)=\frac{340}{450}=0.76[/tex]
What is the answer???
