Anvisha [2.4K]3 years ago
3 0

Answer:

Step-by-step explanation:

First you have to do everything in the brackets, or [ ]. -7+-3--8 is equivalent to 8-3-7, which equals -2. After that you have to do the braces, or {}. That is -5--2, which is the same thing as 2-5, which equals -3. Finally, you can finish it out. -4--2--3 is equivalent to 3+2-4, which equals 1. Hope this helps!

The pyramid below has a square base.
zavuch27 [327]

The volume of the pyramid would be 2406.16 cubic cm.

<h3>How to find the volume of a square-based right pyramid?</h3>

Supposing that:

The length of the sides of the square base of the pyramid has = b units

The height of the considered square-based pyramid = h units,

The pyramid below has a square base.

h = 24.4 cm

b = 17.2 cm

Then, its volume is given by:

V = \dfrac{1}{3} \times b^2 \times h \: \rm unit^3

V = \dfrac{1}{3} \times 17.2^2 \times 24.4 \: \rm unit^3\\\\V = 2406.16

Therefore, the volume of the pyramid would be 2406.16 cubic cm.

james tailoring service charges a flat rate of $20 and charges an additional $12 per hour when making a tailored suit. how much
jeka94

Answer:

It will cost Mr. Smith $68 to make his suit.

Step-by-step explanation:

Since the charge $12 per hour, and it takes 4 hours to make the suit, then we need to multiply 12 by 4.

12 × 4 = 48

Now we need to add the flat rate since that is the initial charge for service.

48 + 20 = 68

This means it will cost Mr. Smith a total of $68 for his suit.
