Answer:

9² = 81

-5⁴ = -625

- 3⁴ = - 81

¼³ = 0.015625

Step-by-step explanation:

Plss follow me and Mark as brainlest. Thanks :-)

Answer:

8. 9^2, this can be simplified to 9*9 which is 81!

9. -5^4 can be simplified to -5*-5*-5*-5 which is 625.

10. (-3)^4 can be simplified to -3*-3*-3*-3 which is 81!

And finally 11. (1/4)^3 can be simplified to (1/4)(1/4)(1/4) which is 1/64.

Answer:

64

Step-by-step explanation:

You just have to add 35 and 29 and the answer is an integer cause it's a whole number.

Answer:

64

Step-by-step explanation:

You are adding more to the first integer 35, so you have to add the next integer 29 to it.

So, the equation would be 35 + 29

First, add 9 and 5 which is 14. Carry the 1 to the next part.

3+2=5

5+1=6

The end result is 64.

Answer:

(0,3)(1,0)

Step-by-step explanation:

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 :) )

Answer:okkkkkkkk

Step-by-step explanation:360

Answer:

is the answer t = $2.00 ?????

Answer:  The variables are the Cost of the item, and the Total cost.

The other cost, the shipping is given here: $2. So that is not really a variable.

You can use almost any letters you'd like. I'm using C for the item's cost,  and T for the total cost in this equation:

C + 2 = T

This question seems to imply that only one item is in the order

Step-by-step explanation:

There may be other ways to do this, if multiple items are ordered.

The variables are the Cost of the item-- and how Many items are purchased.

The Total is also a variable that depends on how many and the cost of the items.

The other cost, the shipping might be a variable in other questions (not here) here: S could be a variable if it is a percentage ot the cost.

You can use almost any letters you'd like. I'm using C for the item's cost, M for the number of items, S for variable shipping, and T for the total cost in this equation:

M×C + S = T

Answer: the difference between the 2 points is 1.1

Step-by-step explanation: the difference between the two points is found by the formula distance= y2-y1/x2-x1

When you plug them in it will be 1.4-2.5/3-3

Answer:

6x+16y+8

Step-by-step explanation:

In order to solve this problem,

6(x+2y)+3+4y+5

We would first need to expand the brackets

6x + 12y + 3 + 4y + 5

Collect like terms together.

6x+12y+4y+3+5

Add the like terms

6x+16y+8

Therefore, the expression which is equivalent to 6(x+2y)+3+4y+5 is 6x+16y+8

Answer:

6x+16y+8

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:

Step-by-step explanation:

Add Hans laps together then divide by two

Answer:

The answer is 118 laps.

Step-by-step explanation:

First you would have to add 89 + 147 to find how many laps Hans ran over the summer.

Then you have to divide  the answer from 89 + 147 by 2 which is 236 divided by two because Hans' laps were twice as much as lee's do when you do 236 divided by 2 you get 118. So, Lee ran, and swan 118 laps.

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
