Circumference Formula: C = πd

d is diameter

Step-by-step explanation:

Step 1: Define

C = 3.14 units

Step 2: Solve for d

Substitute in variable [Circumference Formula]: $3.14 = \pi d$
[Division Property of Equality] Isolate d: $1 = d$
Rewrite: $\displaystyle d = 1$

The perimeter of a rectangle is 34 units. Its width is 6.5 point, 5 units.

12345 [234]

<h3>Question:</h3>

The perimeter of a rectangle is 34 units. Its width W is 6.5 units.

Write an equation to represent the perimeter in terms of the length L, and find the value of L

<h3>Answer:</h3>

The length of rectangle is 10.5 units

<h3>Solution:</h3>

Given that,

Perimeter of rectangle = 34 units

Width of rectangle = 6.5 units

Let "L" be the length of rectangle

The perimeter of rectangle is given by formula:

Perimeter = 2(length + width)

Substituting the values we get,

$34 = 2(L + 6.5)$

Thus the equation is found

Solve for "L"

$L + 6.5 = \frac{34}{2}\\\\L + 6.5 = 17\\\\L = 17 - 6.5\\\\L =10.5$

Thus length of rectangle is 10.5 units

Write the ratio in fractional notation in lowest terms. 28 inches to 42 inches

ivolga24 [154]

28 to 42 means 28/42

We now reduce 28/42 to lowest terms.

28 ÷ 7 = 4

42 ÷ 7 = 6

We now have 4/6.

We now reduce 4/6.

4 ÷ 2 = 2

6 ÷ 2 = 3

Final answer: 2/3

denis-greek [22]

Answer:

You can either factor or use quadratic formula to find where h(x)=0

Step-by-step explanation:

Remember that the ball is on the ground when h(x)=0 since that is the height. There will be two zeros, one is a negative number so would be before you kicked the ball, the other one will be when the ball comes back down.
