9514 1404 393

Answer:

  7. 91 m²

  8. 56 in²

  9. 105 in²

  10. 135 m²

Step-by-step explanation:

The formula for the area of a triangle is ...

  A = 1/2bh

where b is the base length, and h is the height perpendicular to the base.

The formula for the area of a trapezoid is ...

  A= 1/2(b1 +b2)h

where b1 and b2 are the lengths of the parallel bases, and h is the perpendicular distance between them. Note that this formula is virtually identical to the triangle formula, with the triangle 'b' being replaced by (b1+b2).

__

Fill in the numbers and do the arithmetic. The result is shown in the attachment. (We have used the triangle formula for all, with b1+b2 being used for 'b' to find the area of the trapezoids.)

  7. A = 1/2(14 m)(13 m) = 91 m²

  8. 56 in²

  9. A = 1/2(14 +16 in)(7 in) = 105 in²

  10. 135 m²

Answer:

x = 38°

Step-by-step explanation:

Complementary angles = 90°

90° = x + x+14

90° = 2x + 14

104 = 2x

x = 52°

the next angle should be 52 - 14 = 38°

So x = 38°

If my answer is incorrect, pls correct me!

What is the answer for 4a+2b=16
Dmitry_Shevchenko [17]
First, move all terms containing a to the left, all other terms to the right.

Add '2b' to each side of the equation.
4a + -2b + 2b = 16 + 2b

Combine like terms: -2b + 2b = 0
4a + 0 = 16 + 2b4a = 16 + 2b

Divide each side by '4'.
a = 4 + 0.5b

Answer
 

= 4 + 0.5b

Vinil7 [7]

Answer:

It is impossible to simulate this with a random number generator without knowing what the correct answer choices were

Step-by-step explanation:

Given

Questions = 4

Options = 5

Required

How can he select the right answer

Using randint will only generate a random number which could or could not be the answer to the question.

This is so because each of the 5 options for the question has the same probability of 1/5. So, using randint will only generate a random number. This generated random number has 1/5 chance of being the answer and 4/5 of not being the answer to the question.

In a nutshell, he can not make use of a simulator to select the answer to the questions in this scenario, unless he knows the solution.

<em>Hence (a) answers the question.</em>

What is the volume of a hemisphere with a radius of 2.1 m, rounded to the nearest tenth of a cubic meter?
Art [367]

Answer:

The volume of hemisphere is <u>19.4 cubic meter</u>.

Step-by-step explanation:

Given:

A hemisphere is with a radius of 2.1 m.

Now, to find the hemisphere volume with radius 2.1 m.

Radius\ (r) = 2.1 m.

So, we put formula to get the volume of hemisphere:

Volume=\frac{2}{3} \pi r^3\ \ \ \ \ (Taking\ the\ value\ of\ \pi =3.14)\\\\Volume=\frac{2}{3} \times 3.14\times 2.1^3\\\\Volume=\frac{2}{3} \times 3.14\times 9.26\\\\Volume=19.384\ cubic\ meter.

<u><em>Hence, the rounded to the nearest tenth of a cubic meter is 19.4 cubic meter.</em></u>

Therefore, the volume of hemisphere is 19.4 cubic meter.
