Answer: Polyhedron
Step-by-step explanation: A polyhedron is a shape, with 2 parts. Face and Edge, they can only be connected with a edge or a vertex. Only 5 regular polyhedrons exist; tetrahedron ~ 4 faced 'the cube' ~ 6 faced the octahedron ~ 8 faced ~ the dodecahedron ~ 12 faced, and the icosahedron ~ 20 faced.
What is the solution to this equation? 4- 5k = -21
a.5
b.21
c.17 over 5
4 over 5
Answer:
k = 5
Step-by-step explanation:
4 - 5k = -21
Transpose and subtract 4 from both sides:
4 - 4 - 5k = -21 -4
-5k = -25
Divide both sides by -5
-5k/-5 = -25/-5
k = 5

Answer:
7 weeksStep-by-step explanation:
Let the number of weeks be x
Then Kendal's CD's

Answer:
p = 4√5
Step-by-step explanation:
To solve for P, we can use the Pythagorean theorem.
a²+b²=c²
(8)²+(p)²=12²
64+p²=144
p²=80
√p=√80
p = 4√5
Which of the following lines is perpendicular to the line y = -3 x + 2 and passes through the point (–2, 8)?
Answer:
y = 1/3x + 26/3
Step-by-step explanation:
Original equation: y = -3x + 2
Perpendicular lines have the "opposite reciprocal" slopes of each other, meaning you flip the numbers and reverse the sign.
Slope of original equation: -3
Slope of perpendicular line: 1/3
How: Reciprocal, flip the numbers: -3/1 to -1/3, then reverse sign -1/3 to 1/3
Then you substitute (-2, 8) into the new equation: y = 1/3x + b
*there's b because you don't know the y-intercept yet
Substitute: 8 = 1/3(-2) + b
8 = -2/3 + b
Add 2/3 on both sides
b = 24/3 + 2/3
b = 26/3
*this is the y-intercept
Therefore, the perpendicular equation is: y = 1/3x + 26/3

Answer:
[tex]\huge\boxed{66.42 \textdegree}[/tex]
Step-by-step explanation:
In order to solve for this missing angle, we can use trigonometry.
With angle B, we only have two sides: the adjacent of the angle and the hypotenuse of the angle. The adjacent side is the one laying directly next to the angle that isn't the hypotenuse.
Using SOH CAH TOA, we can see that the correct trig function for this would be cos because of CAH (Cosine = Adjacent over Hypotenuse)
Since we know the length of the sides but we don't know the angle, we are going to use inverse trig.
The adjacent side over our hypotenuse will be [tex]\frac{2}{5}[/tex] since 2 is the length of the adjacent and 5 is the length of the hypotenuse.
We know have the equation [tex]cos^{-1}(B) = \frac{2}{5}[/tex].
We now find what [tex]\frac{2}{5}[/tex] is (0.4) and find the inverse cosine of it. We can do this by plugging it into a calculator.
When we do this, we get the number [tex]66.42182152[/tex] etc. Rounding to the nearest hundredth gets us 66.42.

Star A is about 3.4 x10^18 miles from earth. star B is 6.8 x 10^16 miles from earth.Star A is how many times as far from Earth as Star B? I
Answer: It's 50
Step-by-step explanation:
3.4 divided by 6.8 is 0.5 and 18-16 (the exponents) is 2. since ur dividing your subtracting the exponents. so then u get 0.5*10^2 but it cant be lower than 1 so u move the decimal in 0.5 one space to the right which then leads you to get 5*10^1 or 5*10 which is 50.

−207
−21
21
207
Answer:
207
Step-by-step explanation:
It automatically can not be -207 and -21 because you can't have a negative distance. To find the correct answer between 21 and 207, first you have to add 93 and 114. You do this because -93 is below the number line, so you have to add it to 114. 114 + 93 = 207

Sarita showed the steps to solving the equation. 5 (x minus 3) + 7 (x + 4) = 73 Steps Sarita's Solution Sarita's Verification 1 5 x minus 15 + 7 x + 28 = 73 5 (5 minus 3) + 7 (5 + 4) = 73. 5 (negative 2) + 7 (9) = 73. Negative 10 + 63 = 73. 53 not-equal-to 73. 2 (5 + 7) x + (negative 15 + 28) = 73 3 12 x + 13 = 73 4 12 x + 60 5 x = 5 When Sarita tried to verify her answer, she found it was wrong. Which explains her mistake?
Answer:
Sarita’s solution is correct. She made an error in her verification. Sarita was supposed to add the 5 and 7 in the first step.
Step-by-step explanation:
Given the following equation:
The steps to solve it are:
5(x-3)+7(x+4)-73
1. Apply the Distributive property:
5x-15+7x+28=73
2. Add the like terms:
12x+13=73
3. Subtract5 13 from both sides of the equation:
12x+13-(13)=73-(13
12x=60
4. Divide both sides of the equation by 12:
12r/12 = 60/12
x = 5
To verify it, let's substitute into the equation:
5(5-3)+7(5+4)=73
Evaluating, we get:
5(2)+7(9)=73
10+63=73
73=73
Based on this, we can determine that Sarita's solution is correct, but she made an error in her verification (Observe that 5-3 is not equal to -2 )
Answer:
A. Sarita’s solution is correct. She made an error in her verification.

Which rule describes the transformation?
O(x, y) - (x, y)
O (x,y) - (y,x)
O (x,y) - (-x, -y)
O (x, y) - (y, -x)
The rule that describes the transformation is (x, y) → (-x, -y).
Option C is the correct answer.
We have,
From the graph,
A = (-1, -1)
B = (1, -1)
C = (0, -4)
And,
A' = (1, 1)
B' = (-1, 1)
C = (0, 4)
Now,
If we use transformation:
(x, y) → (-x, -y) on each coordinate of A, B, and C.
We get,
A' = (1, 1)
B' = (-1, 1)
C = (0, 4)
Thus,
The rule that describes the transformation is (x, y) → (-x, -y).

If each unit on the coordinate plane represents one mile, what is the total distance the truck travels on its route?
Answer:
36.16 miles
Step-by-step explanation:
A recycling truck begins its weekly route at the recycling plant at point A, as pictured on the coordinate plane below. It travels from point A to point B, then points C, D, and E, respectively, before returning to the recycling plant at point A at the end of the day. The truck’s route is illustrated on the coordinate plane below. If each unit on the coordinate plane represents one mile, what is the total distance the truck travels on its route?
Answer:
The distance between two points X([tex]x_1,y_1[/tex]) and Y[tex](x_2,y_2)[/tex] is given as:
[tex]|XY|=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
From the image attached, the coordinates of the plane are:
A(-1, -1), B(1, -1), C(5, 2), D(0, 13), E(-5, 2).
The lengths are:
[tex]|AB|=\sqrt{(1-(-1))^2+(-1-(-1))^2}=2\ units\\ \\|BC|=\sqrt{(5-1)^2+(2-(-1))^2}=5\ units\\\\|CD|=\sqrt{(0-5)^2+(13-2)^2}=12.08\ units\\\\|DE|=\sqrt{(-5-0)^2+(2-13)^2}=12.08\ units\\\\|AE|=\sqrt{(-5-(-1))^2+(2-(-1))^2}=5\ units[/tex]
But 1 mile = 1 unit
Total distance = |AB| + |BC| + |CD| + |DE| + |AE| = 2 + 5 + 12.08 + 12.08 + 5 = 36.16 miles

Answer:
x = -8
Step-by-step explanation:
Step 1: Write equation
5x - 7(x + 1) = 9
Step 2: Solve for x
Distribute -7: 5x - 7x - 7 = 9Combine like terms: -2x - 7 = 9Add 7 to both sides: -2x = 16Divide both sides by -2: x = -8Step 3: Check
Plug in x to verify it's a solution.
