What is the surface area of the square-based pyramid below? give me the corect awnser for brainlyest

Answers

Answer 1

Answer:

Step-by-step explanation:

square base

32 x 32 = 1024

the two 32 by 34 triangles

32 x 34 ÷ 2 × 2= 1088

the two 30 by 32 triangles

30 x 32 ÷ 2 x 2 = 960

The formula I used to do this was base x height ÷2 but because there were two equal triangles I multiplied a 2 to the end.

Then to add them all up to get

1024 + 1088 + 960 = 3072[tex]in^{2}[/tex]

Mary has $6,000 saved for her college education. She invested that money at 2.3% interest per year. Suppose her account earned interest compounded annually. How much interest would she earn in 3 years?

Answers

Answer:

Interest= $423.59

Step-by-step explanation:

Giving the following information:

Initial investment (PV)= $6,000

Number of periods (n)= 3 years

Interest rate (i)= 2.3% = 0.023

To calculate the Future Value, we need to use the following formula:

FV= PV*(1+i)^n

FV= 6,000*(1.023^3)

FV= $6,423.59

Now, the interest earned:

Interest= 6,423.59 - 6,000

Interest= $423.59

8ounces ham how much will
it Charge for 6ounces?

Answers

Answer:

$1.68

Step-by-step explanation:

[tex]\frac{8}{2.24}=\frac{6}{x} \\8x= 6(2.24)\\8x= 13.44\\x= 1.68[/tex]

Answer:

$1.68

Step-by-step explanation:

Since 8 ounces of deli charges $2.24, 1 ounce costs $0.28 because 2.24 divided by 8 is 0.28. Then, you multiply 0.28 by 6 since you are trying to find how much 6 ounces of deli costs. 0.28 times 6 is equal to 1.68. So, 6 ounces of deli costs $1.68.

Solve for the variable

Answers

Answer:

v = 14

Step-by-step explanation:

3/2 v = 21 (first multiply 2 on both sides)

3v = 42 (divide by 3 on both sides to isolate the variable)
