Answer:
Area of triangles 1 = 18 ft²
Area of triangles 2 = 16 in²
Area of triangles 3 = 90 yd²
Step-by-step explanation:
Given:
1] Height of triangle = 4 ft
Base of triangle = 9 ft
2] Height of triangle = 4 in
Base of triangle = 8 in
3] Height of triangle = 12 yd
Base of triangle = 15 yd
Find:
Area of triangles
Computation:
Area of triangles = (1/2)(Base)(Height)
Area of triangles 1 = (1/2)(4)(9)
Area of triangles 1 = 18 ft²
Area of triangles 2 = (1/2)(4)(8)
Area of triangles 2 = 16 in²
Area of triangles 3 = (1/2)(12)(15)
Area of triangles 3 = 90 yd²
Answer:
There were 120 questions on the test.
Step-by-step explanation:
It is given that:
Number of questions answered = 54
Grade percent = 45%
Let,
x be the total number of questions
45% of x = 54
![\frac{45}{100}x=54\\0.45x = 54](https://tex.z-dn.net/?f=%5Cfrac%7B45%7D%7B100%7Dx%3D54%5C%5C0.45x%20%3D%2054)
Dividing both sides by 0.45
![\frac{0.45x}{0.45}=\frac{54}{0.45}\\x=120](https://tex.z-dn.net/?f=%5Cfrac%7B0.45x%7D%7B0.45%7D%3D%5Cfrac%7B54%7D%7B0.45%7D%5C%5Cx%3D120)
Therefore,
There were 120 questions on the test.
Answer:
Flipping tails would be 1/2 but how many marbles are there and how many orange ones are there?
Step-by-step explanation:
Answer:
Add 42 to itself from h to get the corresponding answer at d
42+42=84
84+42=126
126+42=168
168+42=210
I think its the first option maybe im not sure
