PLZ MARK AS BRAINLIEST

Step-by-step explanation:

Lateral Area of Pyramid:

L = 1/2Pl

l = 15.9

P = 2(8.2) + 2(8.2) = 32.8

L = 1/2(32.8)(15.9) = 260.76

Surface Area:

SA = B + L

B = (8.2)(8.2) = 67.24

L = 1/2(32.8)(15.9) = 260.76

SA = 67.24 + 260.76 = 328

Answer:

25 cm is the perimeter...........

Answer:

25 cm

Step-by-step explanation:

When you are told that any figure is regular it means all the sides have the same value.

A pentagon has 5 sides.

Each side is 5 cm.

The perimeter is the addition of all the sides.

To find it we just multiply

5*5= 25 cm

Answer:

3. Tony's deposit earned $40.80 in simple interest over 3 years in an account with an interest rate of 1.7%. How much did Tony deposit?

Answer:

y = amount saved in dollars

x = months

Since the student already has $20 dollars saved (20) and plans to save $10 per month (10x), the equation so far is y = 20 + 10x.

You can use this to solve questions based of the equation/situation by filling in any numbers you are given where the variables are.

Hope this helps! :)

Step-by-step explanation:

y = amount saved in dollars

x = months

y = 20 + 10x

Ans: y = 20 + 10x

Answer:

y=-3x+8

Step-by-step explanation:

Slope intercept is as follows: y=mx+b

m is the slope so replace the m with -3

y=-3x+b

b is the y intercept, so replace the b with 8 (keep in mind that had the y-intercept been negative, we would have subtracted)

This then gives you

Answer:

28.26

Step-by-step explanation:

A = r^2

So the equation is. Area of circle = pi(3.14) * radius(3) to the power of 2 (^2)

A = 3.14(3)^2

A = 3.14(9)

A = 28.26

6 and 1/2 minus 5 and 3/4 mathematically is equivalent to 3/4 .

Given, 6 and 1/2 minus 5 and 3/4 .

Solve for:

1. First off, convert both of these mixed number fractions into improper fractions.

6 and 1/2 minus 5 and 3/4

= [tex]\frac{13}{2} - \frac{23}{4}[/tex]

2. Find a common denominator

Multiply the numerator and denominator of the first fraction both by 2.

= [tex]\frac{13}{2} - \frac{23}{4}[/tex]

=[tex]\frac{26}{4} - \frac{23}{4}[/tex]

3. Subtract the fractions.

= [tex]\frac{26}{4} - \frac{23}{4}[/tex]

= [tex]\frac{3}{4}[/tex]

Answer:

120³

Step-by-step explanation:

Hi!

This is very easy you just need to know the formula for finding the area of a rectangular prism. I attached something to help you with that but I also have an explanation.

The formula to find the area of a rectangular prism is L x W x H,

or in full words Length x Width x Height.

So now lets see what the problem has given us so we can plug things in.

Length = 4

Width = 3

Height = 10

Wow, it gives us all of it!

So now we just have to plug these numbers into the equation and solve.

So :

Length x Width x Height

   4       x     3    x     10

Now we solve it :

4 x 3 = 12

And then we take 12 and multiply it by the last 10 in the equation.

12 x 10 = 120

And that is your answer, the volume of the rectangular prism!

Make sure to add a ³ after the 120 like so :

120³

This tiny 3 represents volume in math since the shape is 3D.

And if there are units of measurement involved like feet or inches make sure to put that in there as well like so :

120 feet³

I hope this helps!
