Find the volume of both shapes please answer will give brainiest Also please answer neatly.

SSSSS [86.1K]

Answer:

2). Volume = 14400 feet³

3). Volume = 157.5 ft³

Step-by-step explanation:

Both the figures given in the sheet attached are a rectangular pyramid and a triangular prism.

2). In this part of the question solid given is in the shape of an rectangular pyramid.

Volume of this oblique pyramid = $\frac{1}{3}(\text{Base})(\text{Height})$

Here 'B' = area of the base

h = height of the pyramid

Volume = $\frac{1}{3}(25\times 36)\times 48$

= 14400 cubic feet

4). Volume of a triangular cone = (Area of the triangular base)×(height)

= $[\frac{1}{2}(\text{Base})(\text{height})]\times {\text{height of the prism}}$

= $\frac{1}{2}(7\times 9)\times {5}$

= 157.5 ft³

What is the solution of 3x + 5 = 2x – 7?

Schach [20]

Answer:

the x-coordinates of the intersection point of the lines y = 3x + 5 and y = 2x – 7

Step-by-step explanation:

When you set two equations or functions equal to each other that is saying you want to know when the graphs intersect. So the y and x intercept don't matter, unless you combined the terms like this.

3x + 5 = 2x – 7

x + 12 = 0 then that terms x intercept woudl be the x coordinate of the intersection of the other two terms. But remember, this is onlyif you combines the two functions.

Of your options you just want the ones dealing with the intersection point. And of those two we are plugging in x, so we want the x coordinate.

Suppose that a department contains 10 men and 12 women. How many ways are there to form a committee with six members if it must

Readme [11.4K]

Answer:

The number of ways is 26,400 ways

Step-by-step explanation:

Given;

total number of men, M = 10

total number of women, W = 12

number of committees to be formed = 6

If there must be equal gender, then it must consist of 3 men and 3 women.

$The \ number \ of \ ways = 10C_3 \times 12C_3\\\\The \ number \ of \ ways =\frac{10!}{3!7!} \times \frac{12!}{3!9!} \\\\T he \ number \ of \ ways = 120 \times 220 = 26,400 \ ways$

Therefore, the number of ways is 26,400 ways
