Answer 1

Answer:

68.78° or 0.6 rad

Step-by-step explanation:

Use the formula:

degrees/360° = L/circumferenceor radians/π = L/circumference

As per given:

l = 12 feet, r = 10 feet

degrees = 360°*12/(2*3.14*10) = 68.78° radians = π rad *12/(2π*10) = 0.6 rad

A skating rink changes one admission price for adults and a different admission price for children. The total admission price for a group of 4 adults and 10 children is $57. The total admission price for a group of 3 adults and 7 children is $41. What are the admission prices for an adult and for a adult?

Answers

Given:

The total admission price for a group of 4 adults and 10 children is $57.

The total admission price for a group of 3 adults and 7 children is $41.

To find:

The admission prices for an adult and for a children.

Solution:

Let the price of an adult be x and price of children be y.

According to the question,

[tex]4x+10y=57[/tex] ...(i)

[tex]3x+7y=41[/tex] ...(ii)

Multiply equation (i) by 3.

[tex]12x+30y=171[/tex] ...(iii)

Multiply equation (i) by 4.

[tex]12x+28y=164[/tex] ...(iv)

Subtract (iv) from (iii).

[tex]12x+30y-12x-28y=171-164[/tex]

[tex]2y=7[/tex]

Divide both sides by 2.

[tex]y=3.5[/tex]

Put y=3.5 in (i).

[tex]4x+10(3.5)=57[/tex]

[tex]4x+35=57[/tex]

[tex]4x=57-35[/tex]

[tex]4x=22[/tex]

Divide both sides by 4.

[tex]x=5.5[/tex]

Therefore, the price for an adult is $5.5 and price for a child is $3.5.

A local hamburger shop sold a combined total of 488 hamburgers and cheeseburgers on Friday. There were 62 fewer cheeseburgers sold than hamburgers. How
many hamburgers were sold on Friday?

Answers

9514 1404 393

Answer:

275

Step-by-step explanation:

Let h represent the number of hamburgers sold. Then the number of cheeseburgers sold is h-62, and the combined total is ...

hamburgers + cheeseburgers = combined total

h + (h -62) = 488

2h = 550 . . . . . . . . add 62, collect terms

h = 275 . . . . . . . . . .divide by 2

275 hamburgers were sold on Friday.

There were 24 boys and 20 girls in a chess club last year. This year
the number of boys increased by 25% but the number of girls
decreased by 10%.
Find the overall percent change in membership of the club.
10

Answers

Answer:

35%

Step-by-step explanation:

If you take the amount of percent the girls decreased, and the amount the boys increased in percentages, you will have your answer when just adding them together. So the answer is 35% or as in 6 boys joined and 2 girls left. So that gives you a total of 8 joining or leaving the chess club or 35% difference.
