a movie theater charges $8 for adults and $5 for children. If there were 40 people altogether and theater collected $272
Answers
Answer: You can put this solution on YOUR website!
let's call the number of adults a and the number of children c.
so the total adults plus the total children equals 40 or a+c=40 or c=40-a
also we know that 8a+5c=272
substituting c's value in the 1st equation into the 2nd equation we get
8a+5(40-a)=272---->lets distribute that left side---->8a+200-5a=272
now let's combine like terms on either side of the equals sign.
3a=72 a=24
so we have highlight%2824-adults%29
and c=40-a(24)=highlight%2816-children%29

At a grocery store, the price of $3$ cans of soup is $\$6.90$ . At this rate, how much would $10$ cans of soup cost?
Answers
Answer:
23
Step-by-step explanation:
First, you have to divide 10 by 3, which is 3.333... or 3.3. Now you have to multiply that by $6.90. $6.90 x 3.3=22.77. 22.77 rounded to the nearest tenth is 23, so 23 would be your answer. It can aslo be shown as $3 over $6.90, and 10 over x.

Stephen and Diana are traveling towards each other from points that are 276 miles apart. If Diana is traveling 4 mph faster than and they meet after 6 hours, how fast was each traveling?
Stephen is traveling______mph.
Diana is traveling_____ mph.
Answers
Answer:
Step-by-step explanation:
let speed of Stephen=x mph
speed of Diana=x+4
then
6x+6(x+4)=276
divide by 6
x+x+4=276/6=46
2x=46-4=42
x=42/2=21
Stephen is traveling at 21 mph.
Diana is traveling at 21+4=25 mph.

The correct answer is Option B.
Divide 1,200 by 5.
What is equivalent ratio?Equivalent ratios are those that are the same when compared. Two or more ratios can be compared to determine whether or not they are equivalent.Equivalent ratios are two ratios that have the same value. Multiply or divide both quantities by the same number to find an equivalent ratio. It is the same as determining equivalent fractions. Equivalent equations are algebraic equations with the same solution or root. An equivalent equation is created by adding or subtracting the same number or expression from both sides of an equation.Here = 1200tsp / 5c = ?tsp/1c

Determine an expression for dy
dx given that x = sin3
(t)andy = cos3
(t)
Answers
Answer:
[tex]\frac{dy}{dx} =-\sqrt[3]{\frac{y}{x} }[/tex]
Step-by-step explanation:
Recall that using the chain rule we can state:
[tex]\frac{dy}{dt} =\frac{dy}{dx}*\frac{dx}{dt}[/tex]
and therefore solve for dy/dx as long as dx/dt is different from zero.
Then we find dy/dt and dx/dt,
Given that
[tex]x=sin^3(t)\\dx/dt = 3 sin^2(t)* cos(t)[/tex]
And similarly:
[tex]y=cos^3(t)\\dy/dt=-3\,cos^2(t)*sin(t)[/tex]
Therefore, dy/dx can be determined by the quotient of the expressions we just found:
[tex]\frac{dy}{dx} =\frac{dy/dt}{dx/dt} =\frac{-3\,cos^2(t)*sin(t)}{3\,sin^2(t)*cos(t)} =-\frac{cos(t)}{sin(t)}[/tex]
now notice that we can find [tex]cos(t) = \sqrt[3]{y}[/tex] from the expression for y,
and [tex]sin(t) = \sqrt[3]{x}[/tex] from its expression for x.
Therefore dy/dx can be written in terms of x and y as:
[tex]\frac{dy}{dx} =-\frac{cos(t)}{sin(t)}=-\sqrt[3]{\frac{y}{x} }[/tex]
In a recent survey of 288 people, 72 said that their favorite color of car was white. What percent of the people surveyed liked white cars?
Answers
[ “is” means equal to (=) // “what” means x or another variable // “percent” means divided by 100” // “of” means multiplication. ]
Then you solve that equation.
(you can check it by googling what is 25% of 288. )
Based on the number of people who were surveyed in total and the number of people who had their favorite car as white, the percentage is 25%.
There were 288 people surveyed. 72 people preferred a white car color out of all these. The percent is:
= Number if people who prefer white / Number of people surveyed x 100%
Solving gives:
= 72 / 288 x 100%
= 0.25 x 100%
= 25%
In conclusion, the percent of people who liked white cars was 25%.

Answer:
13
Step-by-step explanation:
Start with the smaller sqaure without the x varible which is 7 x 3 = 21
Then the larger square without the varible, 8 x 4 = 32
Now we subtract 21 from 34 and get 13.
So the area for the shaded region should be 13

Factor out 12m²n from the expression:

Write -m as a difference:
12m²n(2m² + m - 2m - 1)
Factor out m from the expression:
12m²n(m(2m + 1) - 2m - 1)
Factor out the negative sign from the expression:
12m²n(m(2m + 1) - (2m + 1))
Factor out 2m + 1 from the expression which gives us the final answer of:
12m²n(2m + 1)(m - 1)
