Answers:
1. The car continues its journey because the portion shows a linear function.
2. The car is waiting at the starting point because the portion shows a constant function.
3. The car is traveling the same distance per unit of time because the portion shows a linear function away from the starting point.
4. The car stops a distance away from the starting point because the portion shows a constant function away from the starting point.

Use the area of a triangle formula which is, A=1/2bh. You will get A=1/2(6)(3).
Answer:
1. 672 inches
Step-by-step explanation:
Question #1
The formula for the volume of a triangular prism is:
V = [tex]\frac{bh}{2}[/tex]
Where V is the volume, b is the area of the base, and h is the height. You are given the volume and the height. Plug those numbers into your equation.
[tex]4704 = \frac{b(14)}{2}[/tex]
Now, solve for b. To do this, you must isolate the variable b.
The first step to do this is to multiply both sides by 2. This will get you:
4704(2) = 14b
9408 = 14b
Now, divide both sides by 14 to get:
672 = b.
Therefore, the area of the base is 672 inches.
Question #2
To solve this problem, separate the figure into 2 shapes. You have a triangle with a base of 6 cm and a height of 6 cm, as well as a semicircle with a radius of 3 cm.
After you do this, find the area of each shape separately.
The formula for the area of a triangle is:
[tex]A = \frac{bh}{2}[/tex],
where A is the area, b is the length of the base, and h is the height. You know the base and the height, so plug those into your equation. You will get:
[tex]A = \frac{6*6}{2}\\\\A = \frac{36}{2}\\\\A = 18[/tex]
Now you know that the area of the triangle is 18 cm^2.
Let's find the area of the semicircle.
The formula for the area of a semicircle is:
A = [tex]\frac{1}{2}[/tex]π[tex]r^2[/tex]
You know the radius, so plug that in to get:
A = [tex]\frac{1}{2}[/tex]π([tex]3^2[/tex])
A = [tex]\frac{1}{2}[/tex]π(9)
Simplify this to get:
A = 4.5π.
Now, either multiply 4.5 by π to get:
14.1371669412 cm^2
or, multiply 4.5 by 3.14 to get:
14.13 cm^2.
Then, add the area of the triangle, 18 cm^2, by the area of the triangle, 14.13, to get:
32.13 cm^2.
Hope this helps!

The value of (7x²+14x) ÷ (x+2) is
Answers
Answer:
7x
Step-by-step explanation:
First, let's factor the expression 7x² + 14x. The greatest common factor of 7x² and 14x is 7x. 7x² / 7x = x, and 14x / 7x = 2, so our factored expression becomes 7x(x + 2).
If we write our expression as a fraction now, we have
[tex]\dfrac{7x(x+2)}{x+2}[/tex]
And cancelling the x + 2 in the numerator and denominator gives us the value 7x.
When you have equations that use “()” without a number in front, add a one.
So our new equation would be 1(7x^2+14x) divided by 1(x+2)

The average length of a female dolphin is about 148 inches (in).What is this length in feet (ft) and inches (in)?
Answers
Answer:
It would be 12(ft) and 4 (in)
Step-by-step explanation:
Divide 148 by 12 then see what you have remaining (4) which is how many inches in a foot is left I guess.
12*12 is 144. Then 148-144 is 4. so its 12 ft and 4 inches i think

if anya mixed 2/3 cups of white paint with 2 2/3 cups blue paint, how many cups of blue paint would she need for 3/4 cups of white paint?
Answers
She needs 3/16 cups of blue paint for 3/4 cups of white paint.
Given that,
if Anya mixed 2/3 cups of white paint with 2 2/3 cups blue paint,
We have to determine,
How many cups of blue paint would she need for 3/4 cups of white paint.
According to the question,
if Anya mixed 2/3 cups of white paint with 2 2/3 cups blue paint,
Let, x cups of blue paint would she need for 3/4 cups of white paint.
To determine the value of x calculation must be done in a single unit by using the unitary method following all the steps given below.
Anya mixed 2/3 cups of white paint = 2 2/3 cups blue paint,
x cups of blue paint = 3/4 cups of white paint.
Therefore,
She needs x cups of blue paint is,
[tex]\dfrac{2}{3} = \dfrac{8}{3}\\\\x = \dfrac{3}{4}[/tex]
Solving the equation,
[tex]\dfrac{2}{3} \times \dfrac{1}{x} = \dfrac{8}{3}\times \dfrac{4}{3}\\\\ \dfrac{2}{3x} = \dfrac{32}{9}\\\\= 2 \times 9 = 3x \times 32\\\\= 18 = 96x\\\\x = \dfrac{18}{96}\\\\x = \dfrac{3}{16}[/tex]
Hence, She needs 3/16 cups of blue paint for 3/4 cups of white paint.
