Hey there!

First; let us understand that there are 360° in a full circle.

<em>This is what we are representing. </em>

We need to find a way to multiply to get the answer.

<u>36% of 360 = 0.36</u>, therefore we need to make 0.36 x 360

<u>Multiply 0.36 x 360 </u>

Therefore, we <u>get 129.6°</u>

Match the numbers in standard notation with the corresponding numbers in scientific notation.

ankoles [38]

Answer:

a) 864,000,000,000 8.64E11

b) 8,640,000,000 8.64E9

c) 86,400,000,000,000 8.64E13

d) 864,000,000,000,000 8.64E14

Step-by-step explanation:

A scientific notation is a way to represent very large values into the decimal form.

Steps to write in scientific notation:

Move the decimal to left before first digit of the given number.

Find the number of times decimal is moved to left.

Put that number in the exponent of e.

So, matching:

a) 864,000,000,000 8.64E11

b) 8,640,000,000 8.64E9

c) 86,400,000,000,000 8.64E13

d) 864,000,000,000,000 8.64E14

The advertised size of a pizza is the length of its diameter. (An 8-inch pizza has a diameter of 8 in)Q1: What is the area of a

Alexxandr [17]

<span>In this question, we assume the pizza is a circle with radius r and diameter d. The radius is also known as (d/2). The area of a circle is A=pie*r^2. Q1: The area of a 16 inch pizza is A = pie * (16/2)^2 = pie * 8^2 = pie *64 = 201.06 in^2. Q2: To determine the cost per slice, just divide the total cost by the number of slices. In this case you would divide 12.50 by 8 (total slices) to get 12.50/8=$1.56/slice. Q3: The cost per square inch of the pizza would be total cost divided by the total area in square inches. This would give you 12.50/201.06 = $0.06 per square inch.</span>

The perimeter of a rectangle is 24 m. The length is 30 m less than five times the width. Find the dimensions of the rectangle. L

Len [333]

Answer:

<h2>width = 7 m</h2><h2>length = 5 m</h2>

Step-by-step explanation:

Perimeter of a rectangle = 2l + 2w

where

l is the length

w is the width

From the question

Perimeter = 24m

The statement

The length is 30 m less than five times the width is written as

l = 5w - 30

Substitute the expression into the above formula and solve for the width

That's

24 = 2( 5w - 30) + 2w

24 = 10w - 60 + 2w

84 = 12w

Divide both sides by 12

w = 7

Substitute this value into l = 5w - 30

That's

l = 5(7) - 30

l = 35 - 30

l = 5

Therefore the dimensions are

width = 7 m

length = 5 m

Hope this helps you

The circumference C of a circle is equal to the product of π and the diameter d.

Lelu [443]

C=3.14 • d

3.14 is pi as a number but it’s non ending :3

D is diameter

C is circumference

Since it said the product of pi and diameter it means d or diameter times pi is c or circumference.

So if

D= i don’t n know maybe 5 find what’s c or te circumference.

So 5 multiplyed by pi or 3.14 is your circumference!

If u need help with the problem please don’t hesitate to ask me! And am purely her to help!!! :3
