why do planets orbit
Answer:
Newton realized that the reason the planets orbit the Sun is related to why objects fall to Earth when we drop them. The Sun's gravity pulls on the planets, just as Earth's gravity pulls down anything that is not held up by some other force and keeps you and me on the ground.

6.7
Step-by-step explanation:
Theres a formula to figure this out. If you know two sides of a right angle triangle you can find the third.
Use the formula a²=b²+c², where a is the side opposite the right angle and b and c are the other sides.
a²=b²+c²
7²=2²+c²
49=4+c²
49-4=c²

hope it helped and have a nice day!1a) Sara sells a car that was priced at $8,500.00. If she makes a commission of 6.5%, how much will she make? *
Answer:
$552.50
Step-by-step explanation:
To find how much she will make, find 6.5% of 8500
8500(0.065)
= 552.5
So, she will make $552.50
Answer:
$552.50
Step-by-step explanation:
The formula we'll use for this is the simple interest formula, or:
[tex]I=P*R[/tex]
Where:
P is the principal amount, $8500.00.
R is the interest rate, 6.5% per year, or in decimal form, 6.5/100=0.065.
To find the simple interest, we multiply 8500 × 0.065 to get that:
The interest is: $552.50

Answer:
y - 0 = -⅔(x - 3)
Step-by-step explanation:
Given a point, (a, b) and slope, m, equation of the line in point-slope form can be written.
Thus:
Substitute (a b) = (3, 0), and m = -⅔ into y - b = m(x - a).
y - 0 = -⅔(x - 3) (the equation in point-slope form)

a street sign is 104 inches tall. How tall is it in feet and inches.
Answer:
8 ft 8 in
Step-by-step explanation:
104/12 = 8.666...
This shows that there are 8 total feet because there are 12 inches in a foot
Then, multiply 8*12 to get 96 in order to get the remainder of the inches left that do not make up one whole foot.
Then subtract 96 from 104 (104-96) to get the remainder which is 8 inches.

A triangle has a base of 16" in height of 1/8 inch what is the area?
Answer:
Area of triangle is 1 inches²
Step-by-step explanation:
We are given:
Base of triangle = 16 inches
Height of triangle = [tex]\frac{1}{8} \:[/tex] inches
We need to find:
Area of triangle
The formula used to find Area of triangle is:
[tex]Area \:of\: triangle=\frac{1}{2}\times b \times h[/tex]
where b is base and h is height.
Putting values and finding area:
[tex]Area \:of\: triangle=\frac{1}{2}\times 16 \times \frac{1}{8}\\ Area \:of\: triangle=\frac{16}{16}\\ Area \:of\: triangle=1\:inches^2[/tex]
So, Area of triangle is 1 inches²
At a bagel shop the first 6 bagels purchased cost 55 cents apiece, and additional bagels cost c cents apiece. If a customer paid $5.70 for 12 bagels, what is the value of c?
Answer:
C = 0.475
Step-by-step explanation:
you divide 5.70 by 12 and get that one bagel costs 0.475 cents. hope this helps!
c=40 is the answer
6x55=330 cents
$570-570 cents (570-330)÷(12-)
=240÷6 (division)
=40 cents
Thus, c=40
