Which is the solution to the equation 3.5 (2 h + 4.5) = 57.75? Round to the nearest tenth if necessary.

Answers

Answer 1
Answer:

Answer:

h = 6

Step-by-step explanation:

Step 1: Distribute

7h + 15.75 = 57.75

Step 2: Subtract 15.75 on both sides

7h = 42

Step 3: Divide both sides by 7

h = 6

Answers

no   power function is a function of the form : where and are constant real numbers and is a variable. The domain of a power function can sometimes be all real numbers, but generally a non-negativity is used to avoid problems with simplifying. The domain of definition is determined by each individual case.

8m

Answers

The greatest common factor is exactly as it sounds: the greatest factors of two or more expressions.

Factorize the numbers and identify all common factors. To get the GCF multiply all common factors:

8m=2\cdot 2\cdot 2\cdot m,\n36m^3=2\cdot 2\cdot 3\cdot 3\cdot m\cdot m\cdot m,\n 12=2\cdot 2\cdot 3.

Common factors are: 2 and 2, their product is 2·2=4, then the greatest common factor is 4.

If the volume of a cylinder with the height of 3 feet is 75 cubic feet, find the surface area of a cylinder in square feet. F25 G50 H80 J30

Answers

Surface area of cylinder = 2πrh+2πr²
Volume of cylinder = 2πr²×h
So:
75 = 2πr²×3
12.5 = πr²
r = 1.99(471140201)

A = 2π×1.99×3+2π×1.99²
   = 62.39(265842) ft²

Final answer:

The surface area of a given cylinder with a volume of 75 cubic feet and a height of 3 feet is calculated to be 80 square feet by first finding the radius from the volume and height, then substituting those into the surface area formula.

Explanation:

To find the surface area of a cylinder, we first need to know the radius. Given the volume (V) of a cylinder is 75 cubic feet and the height (h) is 3 feet, we can use the formula V = πr²h to find the radius (r). Now, since V = 75 cubic feet and h = 3 feet, we can adjust our formula to solve for r: r = √(V/(πh)) = √(75/(3π)) and find the radius to be 2.88 feet. The formula for the surface area (SA) of a cylinder is SA = 2πrh + 2πr². Substituting r = 2.88 feet and h = 3 feet, we calculate the surface area to be 80 square feet. So the answer is H: 80 square feet.

Alfred is taking a trip. He drove 150 mi and then stopped to refuel. He will drive 60 mph to finish his trip. Let x represent the hours it takes for Alfred to complete the rest of his trip, and let y represent the total distance traveled.Complete the function equation that relates Alfred’s total distance traveled to his time.

y =
x +

Answers

Initial distance was 150miles, final distance was 60mph * x(hours it takes for Alfred to complete the rest of his trip)
Therefore y=150 + 60 x
