Can you answer these 3 questions for me plz

A.
$1hr \: 15min = 75min$

$c = 0.22t = 0.22 \times 75 = 16.5$

cost is $16.50

B.

$26.40 = 0.22 \times t$

rearrange to solve for t:

$t = \frac{26.40}{0.22} = 120min$

C. This is the same as part B, only the rate changed

$t = \frac{26.40}{0.25} = 105.6min$

they ask for the greatest number of minutes, so we round down (take the floor of the value).

the answer is 105 minutes.

Phoenix [80]

Answer:

40 bats sold for $42

26 bats sold for $30

Step-by-step explanation:

x + y = 66

42x + 30y = 2460

solve first equation for y and plug in for y in second equation

42x + 30 (66 - x) = 2460

x = 40

y = 66- 40 = 26

Find the circumference pls help.

Triss [41]

Equation for circumference is c = 2(pi)r

r = 1/2(d)

d = 20

So…. r = 1/2(20) = 20/2 = 10

Going back to circumference equation

c = 2(pi)(10) = 2(3.14)(10) = 62.8
