Answer:

56.52 inches

Step-by-step explanation:

The circumference of a circle can be found using:

$c=\pi d$

We know the diameter is 18, and $\pi$ is being rounded to 3.14, so we can substitute them in.

c=3.14*18 <em>Multiply</em>

c=56.52

So, the circumference is 56.52 inches

X solve for the following inequality-1/2 p less than -16 which graph shows the correct solution

valkas [14]

Answer:

See attachment

Step-by-step explanation:

The given inequality is

$- \frac{1}{2}p \: < \: - 16$

We multiply both sides by -2 and reverse the inequality sign to get:

$- 2 \times - \frac{1}{2} p \: > \: - 2 \: \times - 16$

$p \: > \: 32$

We draw an open circle at 32 and draw an arrow to the right as shown in attachment.

marla has 4.55 in dimes and quarters. if she ha s7 more quarters than dimes, how many quarters doe she have?

Jlenok [28]

Answer:

number of dimes is 8

number of quarters is 15

Step-by-step explanation:

let 'd' = number of dimes

let 'd+7' = number of quarters

.10d + .25(d + 7) = 4.55

.10d + .25d + 1.75 = 4.55

.35d = 2.80

d = 8

q = 7 + 8

a light switch works 25% of the time, how many times does it not work if switched on 64 times in a week

alexira [117]

25% of 64 is 16
$\frac{25}{100} = \frac{x}{64} \\ x = \frac{64 \times 25}{100} = \frac{1600}{100} = 16$
it will work properly 16 times
$64 - 16 = 48$
it will not work 48 times
hope this helps
