Answer:

2a + b/4

Step-by-step explanation:

The expression is the sum of two terms (2a + b/4)

The first term is the product (Multiply) of 2 and a (2a)

The second term is the quotient (Divide) of b and 4 (b/4)

A pyramid has a base that is a right triangle with legs measuring 15 cm and 24 cm. The height of the pyramid is 13 cm. What is t

DENIUS [597]

Answer:

$\boxed{780}\ cm^3$

Step-by-step explanation:

The volume of a pyramid is given by the formula ...

V = 1/3·B·h

where B represents the area of the base and h represents the height.

The area of a triangle is given by the formula ...

A = 1/2·b·h

where b represents the length of the base of the triangle, and h represents the height of the triangle.

For a right triangle, the base and height can be taken to be the lengths of the two legs. Then we have

A = 1/2·(15 cm)·(24 cm) = 180 cm²

The volume of the pyramid is then ...

V = 1/3·(180 cm²)(13 cm) = 780 cm³

The volume of the pyramid is 780 cm³.

I need someone to check these answers ASAP.

Reptile [31]

Alright, 1, 2, and 4 are correct but 3 is not.

The error you made could be hard to notice but it was made. So let's put the equation up, 6x-(2x-9)=-31. Your error occurred when you didn;t distribute the negative sign for (2x-9), if you woud have distributed it then the equation would then be simplified into 6x-2x+9=31. You then add like terms and get 4x+9=31, subtract 9 on both sides and you'll get 4x=22. Divide 4 on both sides to isolate the variable and you get x=5.5

5 2/3 gave to her 4 friends how much did each one receive

Olin [163]

Answer:

Let's see what to do buddy...

Step-by-step explanation:

If it is 5 + 2/3

_________________________________

Step (1)

First we have to find all she has :

$5 \frac{2}{3} = 5 + \frac{2}{3} = \frac{5 \times 3}{3} + \frac{2}{3} = \\ \frac{15}{3} + \frac{2}{3} = \frac{17}{3}$

_________________________________

Step (2)

To find how much did each of them receive , we must divided all by the number of her friends which is 4.

So we have :

$\frac{17}{3} \div 4 = \frac{17}{3} \times \frac{1}{4} = \frac{17}{12} \\$

So each of her friends receive 17/12 .

_________________________________

If it is 5 × 2/3

_________________________________

Step (1)

Firs we have to find all she has :

$5 \times \frac{2}{3} = \frac{10}{3} \\$

_________________________________

Step (2)

To find how much did each of them receive , we must divided all by the number of her friends which is 4.

So we have :

$\frac{10}{3} \div 4 = \frac{10}{3} \times \frac{1}{4} = \frac{10}{12} \\$

So each of her friends receive 10/12 .

_________________________________

And we're done.

Thanks for watching buddy good luck.

♥️♥️♥️♥️♥️
