Answer:
Perimeter: 132
Area: 864
Step-by-step explanation:
Perimeter:
Add all the sides, so 30 + 18 + 8 + 18 + 18 + 18 + 4 + 18 = 132
Area:
Split it into two separate rectangles, so the first one would be 18 * 30 = 540. The second one would be 18 * 18 = 324. Then, add 540 + 324 = 864

Given: AB with coordinates of AC-3, -1) and B(2, 1)
A'B' with coordinates of A'(-1, 2) and B'(4,4).
What translation was used?
Answers
Answer:
up 2, right 3
Step-by-step explanation:
up 2, to the right 3.
The translation was 2 units right and 3 units up.
As per the given data:
We are given AB with the coordinates as, A(-3, -1) and B(2, 1).
After translation, AB becomes A'B' with A'(-1, 2) and B'(4, 4).
We can find out the translation by finding out the change in the corresponding coordinates.
For A to A':
Change in x coordinate = -1 - (-3) = -1 + 3 = 2
Change in y coordinate = 2 - (-1) = 2 + 1 = 3
Increase in x coordinate of 2 units = 2 units right.
Increase in y coordinate of 3 units = 3 units up
Hence, the translation was 2 units right and 3 units up.

In his science class, Boris conducted an experiment in which he used a glass prism to make a rainbow. He now wants to find the surface area of the prism. His teacher gets him a paper model of the prism and spreads it into a flat shape called a net. Boris can see that the net has exactly the same number of faces as the prism. The teacher tells Boris that he can use this net to find the surface area of the prism. Use this image of the net of the prism that Boris’s teacher drew to answer the questions in this activity.

When using the given diagram to determine the area of the pentagon by decomposition, which statements are correct?:

(B) Area of ∆ABC = 42 in²
(C) Area of trapezoid = 1/2(14 ÷ 10)8
(D) The area of the pentagon is 180 in²
(E) The area of the pentagon is 138 in²
APPLY TO ALL THAT IS TRUE
Answers
Answer:
Options (B) and (E)
Step-by-step explanation:
Area of ΔABC = [tex]\frac{1}{2}(\text{Base})(\text{Height})[/tex]
= [tex]\frac{1}{2}(14)(6)[/tex]
= 42 in²
Area of trapezoid ADEC = [tex]\frac{1}{2}(b_1+b_2)h[/tex]
[Here, [tex]b_1[/tex] and [tex]b_2[/tex] are the parallel sides and 'h' is the height of the isosceles trapezoid given]
= [tex]\frac{1}{2}(10+14)(8)[/tex]
= 96 in²
Area of the pentagon = Area of triangle ABC + Area of trapezoid ADEC
= 42 + 96
= 138 in²
Therefore, Options (B) and (E) are the correct options.

(x+5)(x-4)(x+2) is identical to x^3+ax^2
Answers
Answer:
a = 3
Step-by-step explanation:
Factorize (x+5)(x-4)(x+2)
(x+5)(x-4)(x+2)
= (x²-4x+5x-20)(x+2)
= (x²+x-20)(x+2)
= (x³+2x²+x²+2x-20x-40)
= x³+3x²-18x -40
Compare with x^3+ax^2
3x² = ax²
3 = a
Rearrange
a = 3
Hence the value of a that makes the expressions identical is 3
What is the probability of rolling a 3 on a six-sided cube AND rolling a 6 on a six-sided cube?
ob
Answers
Answer:
The probability of not rolling a 5 AND not spinning a 5 is (5/6)*(4/5)=20/30
Step-by-step explanation:
These are independent events.
The probability of rolling a 5 is 1/6.
The probability of spinning a 5 is 1/5.
The probability of rolling a 5 or spinning a 5 is 1/5+1/6=11/30 but you have to subtract 1/30 because you can roll a 5 and spin a 5 at the same time. Therefore 11/30-1/30=10/30=1/3.
There are 30 outcomes. Roll first then spin to get the following outcomes:
11,12,13,14,15,21,22,23,24,25,31,32,33,34,35,41,42,43,44,45,51,52,53,54,55,61,62,63,64,65
You want to roll a 5 OR spin a 5. How many combinations have a 5 ? 10 combinations have a 5.
(you don't count 55 twice) There are 10 combinations with a 5 out of a possible 30 combinations.
Another way of looking at the problem is the following:What is the probability of NOT rolling a 5 AND NOT spinning a 5 ?
The probability of not rolling a 5 AND not spinning a 5 is (5/6)*(4/5)=20/30. Therefore the probability of rolling a 5 or spinning a 5 is 1-20/30=10/30.

Answer: a=101 b=79 c=83 d=97
Step-by-step explanation:
A: angles on a straight line add up to 180° so you would take away 79° from 180° which is 101°.
B: angles on a parallel lines are always the same, you can see that 79 is at the same position as b.
C: opposite angles are always the same so it would still be 83°.
D: d is on other side as c and this would add up to 180° so as we already know that c is 83° you would have to take away 83° from 180° to get d.

a building 62 feet tall casts a shadow 21 meters long . at what angle is the sun shining on the building?
Answers
9514 1404 393
Answer:
42.0°
Step-by-step explanation:
To compute the angle, we need the measures in compatible units. It can be convenient to convert feet to meters.
Tan = Opposite/Adjacent
tan(angle of elevation) = (building height)/(shadow length)
angle of elevation = arctan((62 ft)(0.3048 m/ft)/21 m) = arctan(18.8976/21)
angle of elevation ≈ 41.984°
The angle of elevation of the sun is about 42.0°.

Draw the following triangle after a translation 1 unit to the left and 1 unit up.
HELP
Answers
Step-by-step explanation:
move the shape 1 square to the left and then move it one square up
The triangle after a translation 1 unit to the left and 1 unit up will have vertices at (2, 2), (-4, 4), and (-2, 0).
Translation is a rigid transformation that moves each point of a figure a certain distance in a specified direction. For this triangle, we will translate all its vertices 1 unit to the left and 1 unit up.
Impact on the Coordinates:
Let's consider each vertex of the triangle and apply the translation:
a) Vertex (3, 1):
After the translation, this point will move 1 unit to the left and 1 unit up. Therefore, the new coordinates will be (3 - 1, 1 + 1) = (2, 2).
b) Vertex (-3, 3):
This point will also move 1 unit to the left and 1 unit up. The updated coordinates will be (-3 - 1, 3 + 1) = (-4, 4).
c) Vertex (-1, -1):
Similarly, this point will undergo the translation, resulting in (-1 - 1, -1 + 1) = (-2, 0).
New Triangle:
Now, we have the new coordinates for the vertices after the translation:
Vertex 1: (2, 2)
Vertex 2: (-4, 4)
Vertex 3: (-2, 0)
The transformed triangle will have vertices at (2, 2), (-4, 4), and (-2, 0).
