PLS HELP!! A group of friends went out to eat. The bill came to $75.50 and was subject to 8.25% sales tax. The group then added 18% tip to the total after tax. What was the total the group paid, including sales tax and tip?

So we want to find the surface area of this pyramid. Finding the surface area of a 3D shape is essentially finding the area of all its sides and adding them together.

What we're going to have to do here is find the area of the base of the pyramid, which is basically a square, and find the area of all four sides of the pyramid, which are triangles.

Formula for area of a square: length × width

Formula for area of a triangle: (base × height) ÷ 2

First we will find the area of the base:

l × w = A

(Write out formula)

8 × 8 =

(Input values)

A = 64 m^2 (square meters or meters squared)

(We have our answer, dont forgot to write your units.)

So we've figured out the area of the base. Now onto the triangles:

(b×h) ÷ 2 = A

(Write out formula)

(8 × 6) ÷ 2 =

(Input values)

48 ÷ 2 =

(Use PEMDAS to solve this correctly. We did whatever was in the parenthesis first, which was multiplication.)

A = 24m^2 (square meters or meters squared)

(We have our answer.)

Now we've found the area of the base of the pyramid and one of the sides of the pyramid, but we're almost done! There's four sides to the pyramid, they're all the same. So since we found the area for one, we can multiply that by 4 to find the area of all sides added together:

24 × 4

(area of a side × total sides)

= 96m^2

All that's left is adding the 96 to the area of the base to get our total surface area of the pyramid:

96 + 64 = 160

The surface area of the pyramid is 160m^2(square meters or meters squared)

(Hope this helps :) )

For every 1 cup of sugar, you should use 4 cups of flour in the recipe.

Given that:

Recipe ratio: 3/4 cup of sugar for every 3 cups of flour

To find out how much flour should be used for every 1 cup of sugar,

We can use the concept of ratios.

Step 1: We know that the ratio of sugar to flour is 3/4 to 3.

To make the ratio easier to work with, let's scale it up by multiplying both sides by 4, which gives us 3 cups of sugar to 12 cups of flour.

Step 2: Now, we have the ratio 3 cups of sugar to 12 cups of flour.

To find out how much flour is needed for 1 cup of sugar, we need to divide both sides of the ratio by 3.

After simplifying, we get 1 cup of sugar to 4 cups of flour.

Therefore, for every 1 cup of sugar, you should use 4 cups of flour in the recipe.

Answer:

60m

Step-by-step explanation:

4×6=24 so you have that first chunk of the left side.

since 12-4= 8 you can tell that the bottom of the "triangle" is 8m

3x8÷2=12 so now youhave one part left.

since we have already inferred that the base of the triangle was 8m we know that the length of the rectangle was 8m. 8×3=24

now you add the three values. 24+12+24=60
