4^2 + 5 • 3^2 – 4^2 ÷ 2^3

Answers

Answer 1

Answer: Following the order of operations:
4^2 + 5 * 3^2 – 4^2 / 2^3
16 + 5 * 3^2 – 4^2 / 2^3
16 + 5 * 9 – 4^2 / 2^3
16 + 5 * 9 – 16 / 2^3
16 + 5 * 9 – 16 / 8
16 + 45 – 16 / 8
16 + 45 – 2
61 – 2
59

The answer is 59

Answer 2

Answer: Remember BEDMAS
Brackets, Exponents, Division or Multiplication ( left to right), Addition or subtraction ( left to right)
And the dot between 5 and 3^2 means multiply.
4^2 + 5 · 3^2 - 4^2 ÷ 2^ 3

4×4 + 5 · 3×3 - 4×4 ÷ 2×2×2
16 + 5 · 9 - 16 ÷ 4×2
16 + 45 - 16 ÷ 8
16 + 45 - 2
61 - 2
59

Brain was asked to round 4.44 to the nearest tenth and said it was 4.5 Is he correct?Why or Why not?

Answers

Brian (I think you meant Brian haha..) is incorrect because the tenth place is the number right after the decimal which is a 4. If you are rounding to the tenth place that means that you have to look at the number to the right of that, which is 4. 5 and up means you round up and 4 and down means you round down. This is a 4, so you keep the 4 after the decimal and get rid of the last 4. Therefore, when rounded it would be: 4.4.
Hope this helped! Good luck! :)

The answer is 4.4 hope i helped :)

How would you convince someone that the number 0.57 is a rational number? (PLZ HELP ASAP!! D:)

Answers

it is a rational number since the number does not go on forever and is not spontaneous. ( you can tell that no numbers come after this) Pi would be irrational since it goes on forever and does not have a certain pattern.

Rational numbers are numbers that end. They dont continue forever. In .57 its a rational number because theres only two numbers it doesnt keep going.

A prism has a surface area of 75 feet. Which sentence describes the effect of measuring the surface area in square inches.a. surface area decreases.
b. the surface area increases.
c. surface area stays same, but the number representing the surface area decreases.
d. the surface area stays same, but the number representing the surface area increases.

Answers

The surface stays the same, but the number representing the surface area increases. explanation (: - The measurement you already have is the surface area in square feet. so when you measure the same thing only in square Inches the shape doesn't change. Because there are 12 inches in 1 foot, the number will increase.

Answer: d. the surface area stays same, but the number representing the surface area increases.

Step-by-step explanation:

When you convert feet to inches, the "amount" stays the same, but the number that you are seeing increases. That is because you need 12 inches for every foot.

a composite figure is formed by combining a square and a triangle its total area is 32.5 ft2 the area of the triangle is 7.5 ft2 what is the length of each side of the square

Answers

The length of each side of the square is 5ft

Area of a composite function

Area of the composite figure = area of square + area of a triangle

Substitute the given information

32.5 = Area of square + 7.5

Area of square = 32.5 - 7.5

Area of squar = 25.0 ft^2

Since Area of square = L^2

L = 5ft

Hence the length of each side of the square is 5ft
