1000 tickets were bought at a concert. the amount needed to buy a children’s ticket was $4.50 and the amount needed for an adult

Sholpan [36]

Answer:

The number of children's tickets bought was 300 and the number of adult tickets bought was 700

Step-by-step explanation:

Let

x ----> the number of children's tickets bought

y ----> the number of adult tickets bought

we know that

$x+y=1,000$

$x=1,000-y$ -----> equation A

$4.50x+8.50y=7,300$ -----> equation B

Solve the system by substitution

substitute equation A in equation B

$4.50(1,000-y)+8.50y=7,300$

solve for x

$4,500-4.50y+8.50y=7,300$

$4y=7,300-4,500$

$4y=2,800$

$y=700$

Find the value of x

$x=1,000-700=300$

therefore

The number of children's tickets bought was 300 and the number of adult tickets bought was 700

Delia is a graphic designer who charges an hourly rate. She made the graph to show her total earnings for various numbers of hou

stich3 [128]

Answer:

approximately 7 hours

see the explanation

Step-by-step explanation:

The picture of the question in the attached figure

Let

x ----> the time worked in hours

y ----> the amount earning in dollars

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form $k=\frac{y}{x}$ or $y=kx$

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

In this problem we have a proportional relationship

step 1

Find approximately how many hours would it take Delia to earn $250 ?

Looking at the graph

For y=$250 The value of x is approximately 7 hours

see the attached figure N 2

step 2

Find the exact value

from the graph take the point (5,175)

Find the value of k

$k=\frac{y}{x}$ ----> $k=\frac{175}{5}=\$35\ per\ hour$

The linear equation is

$y=35x$

For y=$250

substitute

$250=35x$

solve for x

$x=7.14\ hours$

Find the volume of a right circular cone that has a height of 12.2 cm and a base with a circumference of 18.5 cm. Round your ans

grin007 [14]

We have been given that a right circular cone has a height of 12.2 cm and a base with a circumference of 18.5 cm. We are asked to find the volume of the cone to nearest tenth.

We know that circumference of circle is equal to $2\pi r$ .

$2\pi r=18.5$

$r=\frac{18.5}{2\pi}$

$r=2.944366$

Now we will use volume of the cone formula to solve our given problem.

$V=\frac{1}{3}\pi r^2 h$

$V=\frac{1}{3}\pi (2.944366)^2\cdot (12.2)$

$V=\frac{1}{3}\pi (8.669291141956)\cdot (12.2)$

$V=\frac{1}{3}\pi (105.7653519318632)$

$V=\frac{1}{3}(332.2716526334804752)$

$V=110.7572175$

Upon rounding to nearest tenth, we will get:

$V\approx 110.8$

Therefore, the volume of the given cube would be approximately 110.8 cubic centimeter.
