Answer:
B. Angles that add up to 180°
Step-by-step explanation:
I think that's the answer because supplementary angles add up to 180°
Complete the square 6v^2-12v-18=0 showing work
see question above to solve
Answer:
b = 30°
Step-by-step explanation:
a + b + 90° = 180°
60° + 90° + b = 180°
150° + b = 180° ( subtract 150° from both sides )
b = 30°
Write C if the figures are congruent, S if they are similar and N if they are neither congruent nor similar.
answer:
1. C
2. N
3. S
4. S
5. C
step-by-step explanation:
1 — the figures are the same so congruent2 — the figures are very different so neither3 — the figures look alike but not the same so similar4 — the figures look alike but not the same so similar5 — the figures are the same so congruentdrag each expression to show whether it is equivalent to 3 time times 9 or to 2x3x9
Answer:
The answers to your questions are given below
Step-by-step explanation:
A. 3 × 9 = 27
B. 2 × 3 × 9 = 54
Next, we shall determine which option will give the same result obtained above.
9 × 3 = 27
9 × 3 × 2 = 54
3 × (4 + 5) = 3 × 9 = 27
(2 × 3) × 9 = 6 × 9 = 54
Therefore,
3 × 9 = 27
9 × 3 = 27
3 × (4 + 5) = 27
2 × 3 × 9 = 54
9 × 3 × 2 = 54
(2 × 3) × 9 = 54
SUMMARY
3 × 9 >>>>>>>>> 2 × 3 × 9
9 × 3 >>>>>>>>> 9 × 3 × 2
3 × (4 + 5) >>>>> (2 × 3) × 9

Determine which lines are parallel and which are perpendicular. Explain your reasoning.
Answer:
Parallel: a and b, p and q, p and r, q and r
PErpendicular: p&a, p&b, q&a, q&b, r&a, r&b
Step-by-step explanation:
Parallel lines have the same slope so both of the lines would be going in the same direction and will never cross each other.
Perpendicular lines cross at a 90 degree angle.
Technically you do not know if q&a and q&b are perpendicular because you do not know if there is a 90 degree angle
Answer:
Parallel lines are equally spaced out in the same direction so it would be p,q, and r, Purpendicular Lines intersect at a 90 degee angle so it would be q and a, q and b, r and b, and r, and so on

Explain how to use a net to find the surface area of a prism
ANY ABSURD ANSWERS WILL BE REPORTED IMMEDIATELY
Answer:
use a net to fin surface area of a prism by multyplying 10 to the power of 50
Step-by-step explanation:
Answer:
To find the total surface area of a prism, you need to calculate the area of two polygonal bases, i.e., the top face and bottom face. And then calculate the area of lateral faces connecting the bases. Add up the area of the two bases and the area of the lateral faces to get the total surface area of a prism.
Step-by-step explanation:

An jet travels at a constant speed of 320 miles per hour. How far, in miles, will the jet travel in 15 minutes?
Answer:
80 miles
Step-by-step explanation:
15 minutes = 1/4 hour
distance = speed * time
d = 320 * 1/4
d = 80 miles

Melissa and Jaime are playing a game in geometry class. Melissa draws the shape below on plain white paper and has to give Jaime directions to draw a congruent shape.
I. The location of each vertex on a coordinate plane
II. The shape is a triangle. Its two longest sides measure 6 inches and 3√3 inches.
III. m∠MEL = 90°, m∠ELM = 30°, and LM = 6 inches
Which of the following descriptions of Melissa's triangle is adequate for Jaime to draw a congruent shape?
Answer:
III. m∠MEL = 90°, m∠ELM = 30°, and LM = 6 inches
Step-by-step explanation:
It´s lll Because to make a congruent shape one angle should be 90 and the longest side should be 6 inches. one angle should equal angle ELM.
So, by AAS criteria it would be congruent.

Q8. Look at the image.
Answer:
Option B
Step-by-step explanation:
Quadratic equation given in the question is,
[tex]x^2+4x+2=0[/tex]
By comparing this equation with the standard quadratic equation,
[tex]ax^2+bx+x=0[/tex]
[tex]a=1,b=4[/tex] and [tex]c=2[/tex]
By using quadratic formula to get the roots of the given quadratic equation,
[tex]x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]
By substituting the values of a, b and c in the formula,
[tex]x=\frac{-4\pm\sqrt{4^2-4(1)(2)}}{2(1)}[/tex]
[tex]x=\frac{-4\pm\sqrt{16-8}}{2}[/tex]
[tex]x=\frac{-4\pm\sqrt{8}}{2}[/tex]
[tex]x=\frac{-4-\sqrt{8}}{2},\frac{-4+\sqrt{8}}{2}[/tex]
[tex]x=-3.414,-0.5857[/tex]
[tex]x=-3.41,-0.59[/tex]
Therefore, Option B will be the answer.
Find the volume of the prism
Answer:
Step-by-step explanation:
The formula for the volume of a prism is V=Bh , where B is the base area and h is the height. The base of the prism is a rectangle. The length of the rectangle is 9 cm and the width is 7 cm.
Find the Volume (look at the picture)
Answer:
V ≈ 263.9 units³
Step-by-step explanation:
The volume (V) of a cone is calculated as
V = [tex]\frac{1}{3}[/tex] πr²h ( r is the radius and h the height )
Here r = 6 and h = 7 , then
V = [tex]\frac{1}{3}[/tex] π × 6² × 7
= [tex]\frac{1}{3}[/tex]π × 36 × 7
= [tex]\frac{1}{3}[/tex]π × 252
= 84 π
≈ 263.9 units³ ( to 1 dec. place )

Carl and Tamera want to compare their tests in math class. They have taken six tests. Should they use the mean, median or mode to compare their scores?
Answer:
Mean
Step-by-step explanation:
I said mean because it would allow both Carl and Tamera to average their scores and compare one side by side rather than comparing 6 each which would just be time consuming and it seems like it wouldn't be any other choices.

If g(x) = 2x + 1 and f (x) = x2 + 4, find g[f(4)].
g[f(4)] =
Answer:
g(f(4)) = 41
Step-by-step explanation:
Evaluate f(4) then substitute the value obtained into g(x)
f(4) = 4² + 4 = 16 + 4 = 20, then
g(20) = 2(20) + 1 = 40 + 1 = 41
That is g(f(4)) = 41

Marcus is choosing 4 books to read from a list of 15 books. If order matters, how many ways can he choose to read the books?
4
32,760
23,760
60
Answer:
32,760
Step-by-step explanation:
Given :
Since the order matters, we use the permutation relation :
Recall :
nPr = n! ÷ (n - r)!
n = 15 ; r = 4
15P4 = 15! ÷ (15 - 4)!
15P4 = 15! ÷ 11!
15P4 = (15 * 14 * 13 * 12)
15P4 = 32,760
