Answer:
A. 201 cm³
Step-by-step explanation:
To find the volume, we need to know the length of the prism and the area of the triangular base.
We can find the area of the triangular base a couple of ways. Since we are given some angles, the convenient way will be to make use of those angles.
The triangular base is isosceles. For our purpose, we assume that means AB = BC. If we define point M as the midpoint of AC, then triangle BMC is a right triangle with a base of (9 cm/2) = 4.5 cm.
The side BC can be found from the trig relation ...
cos(∠BCA) = CM/BC
BC = CM/cos(∠BCA) = (4.5 cm)/cos(50°) ≈ 7.00
Then the area of the end triangle ABC is ...
base area = (1/2)(AC)(BC)sin(50°)
base area = (1/2)(9 cm)(7 cm)sin(50°) ≈ 24.133 cm²
__
The length CF can be found from the relation ...
tan(40°) = EF/CF
CF = EF/tan(40°) = (7.00 cm)/tan(40°) ≈ 8.343 cm
Then the volume of the prism is ...
V = Bh
V = (24.133 cm²)(8.343 cm) ≈ 201 cm³
The volume of this isosceles triangular prism is about 201 cm³.
Answer:
A. 201 cm³ is the answer.

area of rectangle=length x width
7x20=140
area of square = side^2
5x5=25
140+25=165
hope that answers your question
Step-by-step explanation:
Answer:
165 in^2
Step-by-step explanation:
Split the polygon and make 1 rectangle and 1 square.
Now you got a 5x5 square and a 7x20 rectangle
Do the square one first...
5 x 5=25 in
Now do the rectangle one...
7 x 20=140 in
Last add them...
25+140=165 in^2

C. 1/4
D. 1/8
Answers
Answer:
Step-by-step explanation:
2^3 . 2^- 5 . 2^- 1
= 2^( 3 - 5 - 1 )
= 2^( 3 - 6 )
= 2^- 3
= 1 / 2^3
= 1 / 8
If
2 . 2^3 . 2^- 5 . 2^- 1
= 2^1 . 2^3 . 2^- 5 . 2^- 1
= 2^( 3 - 5 - 1 + 1 )
= 2^( 3 - 5 )
= 2^- 2
= 1 / 2^2
= 1 / 4

7(left answer), 3(top left answer), and 10(top right answer)
Step-by-step explanation:
So what are two things that go into 21?
21 and 17 and 3Out of those two, which is a factor of 70? Right off the bat we know 7 is.
THis isnt the greatest factor of 70, but it is for both 21 and 7, so now we know the left answer for hieght is 7.
Now 3 must be the top left answer, because you must make 21 with 7. 7 Goes into 21 3 times, so it has to be 3. So now we know that the top left anhswer is 3.
Finally we have our top right answer. We already know that the height is 7, now we need to find the width. All we have to do is divide 70 by the 7 heigh, and we will find our width:
70/7
=
10
So now we know that the top right answer is 10.

∛44x-7 -5=0 find the x
Answers
Answer:
x = 3.
Step-by-step explanation:
(∛44x - 7) - 5 = 0
Cube the expression.
44x - 7 - 125 = 0
Subtract.
44x - 132 = 0
Add 132 to both sides.
44x = 132
Divide by 44.
x = 3.
Proof:
(∛44x - 7) - 5 = 0
(∛44(3) - 7) - 5 = 0
(∛132 - 7) - 5 = 0
(∛125) - 5 = 0
5 - 5 = 0
0 = 0

How do I solve this arithmetic sequence?
Answers
Answer:
The 16ᵗʰ term of this sequence is 82
Step-by-step explanation:
Here,
First Term = a₁ = 9
Common Difference = (d) = 2
Now, For 16ᵗʰ term, n = 16
aₙ = a + (n - 1)d
a₁₆ = 7 + (16 - 1) × 2
a₁₆ = 7 + 15 × 5
a₁₆ = 7 + 75
a₁₆ = 82
Thus, The 16ᵗʰ term of this sequence is 82

suzanne is running a 5km race. so far she has ran 1,250m. how many more meters does she need to run to complete the race?
Answers
Answer: 3750 m
Step-by-step explanation:
Remember that there are different units; one is in km and the other is in m
I’ll go from km to m
1 km = 1000 m
Therefore 5 km = 5 x 1000 m
5km = 5000 m
Now, we just subtract to find how much more Suzanne have to run
5000 m - 1250 m = 3750 m
