Lerok [7]3 years ago

4 0

Answer:

5 more men

Step-by-step explanation:

10 men do a job in 6 hours.

To do the job in 2 hours, 1/3 of the time, you need 3 times as many men.

30 men do a job in 2 hours.

To do the job in twice the time, 4 hours, you need half the men.

15 men do a job in 4 hours.

15 men - 10 men = 5 men

You need 5 more men.

Answer:

2,601

Step-by-step explanation:

You have to find the hypotenuse using the formula $c^{2} =\sqrt{a^2 + b^2$ to find the length of the square which would be c. $=\sqrt{ 24^{2}+45^2 }$ giving you an answer of 51. To find the area of the square you need to multiply 51 to itself so, $51*51=2,601$ .

Select the correct answer.

Alik [6]

The final product of the given expression is 36 41/29

<h3>Given the expression below;</h3>

(3 2/3 * 3 3/2) * (4 2/3)

Expand using the distributive property to have;

(3 2/3 * 4 2/3) * (3 3/2 * 4 2/3)

Simplify the parenthesis to have;

(11/3 * 14/3) * (9/2 * 14/3)

154/9 * 126/6

36 41/29

Hence the final product of the given expression is 36 41/29

What is the approximate volume of the cone?

Mnenie [13.5K]

Answer:

A. 1206 cm³

Step-by-step explanation:

We have a cone and are asked to find the approximate volume of it.

Keep in mind we are using π for 3.14

The forumla of a cone is V = πr² $\frac{h}{3}$

We know the radius = 12

and the height = 8

Substitute :

V = π12² $\frac{8}{3}$

Since these are multiplied with each other, we can first start off with multiplying the fraction, including with factoring 12²:

V = $\frac{2^4*3^2*8\pi }{3}$

Cancel the common factor - 3 :

V = $2^4 * 8 * 3\pi$

Multiply 8 and 3π :

V = $2^4 * 24\pi$

Solve the exponent :

V = $16 * 24\pi$

Multiply :

V = $384\pi$

Multiply for the final answer :

1205.76 cm³

which can be rounded up to

A. 1206 cm³
