Ice cream is packed in cylindrical gallon tubs. A tub of ice cream has a total surface of 387.79 square inches. If the diameter of the tub is 10 inches, what is it's height? use n = 3.14.
7.35 inches
7.65 inches
14.7 inches
17.35 inches

Answers

Answer 1

Answer: The required height of the tub is given as 7.35 inches.

Step-by-step explanation:The total surface area of the given cylindrical tub = 387.79 in.²

The diameter of the tub = 2r =  10 inches

where r = radius

r = 10/2 = 5 inches

T total surface of a cylinder = 2πr² + 2 π rh

387.79 = 2 * 3.14 * 5*5 + 2 * 3.14 * 5 * h

387.79 - 157 = 31.4h

h = 7.35 inches

Answer:

You have to multiply both sides by 9 instead of just the left side

X = 27

Step-by-step explanation:

x/9 = 3

9 * x/9 = 3 * 9

X = 27

In order to solve this problem you MUST know the INVERSE PROPERTY RULE. It’s pretty simple. For example in this problem x/9=3, what is 9 doing to the x? It’s dividing it. And the opposite of dividing is multiplying. So in order to isolate the x you must multiply 9 on both sides. Because whatever you do on one side you must do to the other. So far your equation should look like this: 9*x/9=3*9. And the 9/9 cancel each other out. Leaving x=3*9. And that will be 27. So x=27.

The error they made here was that they didn’t they didn’t multiply 9 on BOTH sides just on one. Leaving this problem incomplete.

The singh family orderd a large pizza with a diameter of 20 inches for dinner. If one of the members ate one-eighth of the pizza, how many square inches of pizza are remaining? (use 3.14 for pi)

Answers

Answer:

275.5 square inches of pizza remaining

Step-by-step explanation:

The area of a circle can be calculated using the formula A = πr^2, where r is the radius of the circle.

The diameter of the pizza is 20 inches, so the radius is half of that, or 10 inches.

The area of the entire pizza is:

A = πr^2 = 3.14 x 10^2 = 314 square inches.

If one member of the family ate one eighth of the pizza, then the amount of pizza remaining is 7/8 of the original amount.

The remaining area of the pizza is:

(7/8) x 314 = 275.5 square inches.

Therefore, there are 275.5 square inches of pizza remaining.

Gianna and her family went for a drive. They traveled 175 miles in 3 hours. What was their average speed?


Would you write an inequality or an equation?

Answers

To find the average speed, we divide the total distance traveled by the time taken:

Average speed = Total distance ÷ Time taken

Therefore, Gianna and her family's average speed is:

Average speed = 175 miles ÷ 3 hours = 58.33 miles per hour (rounded to two decimal places)

We use an equation to solve this problem.

Equation: Average speed = Total distance ÷ Time taken

Where:

Total distance = 175 miles

Time taken = 3 hours

Substituting these values into the equation, we get:

Average speed = 175 miles ÷ 3 hours

Therefore, the answer is an equation:

Average speed = 175 miles ÷ 3 hours

The answer would be 175 divided by 3.

A dinner plate has a circumference of 125.6 cm. What is the area of the dinner plate? (Use 3.14 for π)
A. 251.2 cm2
B. 1,256 cm2
C. 62.8 cm2
D. 2,512 cm2

Answers

Answer: B. 1256 cm2

area = 3.14 r^2
circumference = d * 3.14

To solve:
First we need to work backwards from the circumference to find the diameter- we start with 125.6 = 3.14 * d. We then divide by 3.14 to get 40 = d. Divide by 2 to get the radius and we get 20 cm. Then, we plug the radius into the area formula, getting us 3.14 * 20^2. 20^2 = 400, so we get 3.14 * 400. 3.14 * 400 = 1256, so the area is 1256 cm2.

How much alcohol must a pharmacist add to 10 cm^3 of an 8% alcohol solution to strengthen it to an 80% solution? PLS ANSWER URGENT THANKS

Answers

The pharmacist must add [tex]36 cm^3[/tex] of pure alcohol to the [tex]10 cm^3[/tex] of 8% alcohol solution to obtain an 80% alcohol solution.

What is alcohol ?

Alcohol, also known as ethanol is a clear, colorless liquid that is produced by the fermentation of sugars and carbohydrates by yeasts.

Let's start by writing down the equation that relates the amount of alcohol in the original 8% solution to the amount of alcohol in the final 80% solution:

[tex]0.08 x 10 cm^3[/tex] [tex]+ x = 0.80 x (10 cm^3 + x)[/tex]

Here, x represents the amount of pure alcohol that we need to add to the [tex]10 cm^3[/tex] of 8% solution to obtain the desired 80% solution.

The left-hand side of the equation represents the amount of alcohol in the original solution (which is 8% alcohol), while the right-hand side represents the amount of alcohol in the final solution (which is 80% alcohol).

Now we can solve for x:

[tex]0.08 x 10 cm^3 + x = 0.80 x (10 cm^3 + x)[/tex]

[tex]0.8 cm^3 + x = 8 cm^3 + 0.8x[/tex]

[tex]0.2x = 7.2 cm^3[/tex]

[tex]x = 36 cm^3[/tex]

Therefore, the pharmacist must add [tex]36 cm^3[/tex] of pure alcohol to the [tex]10 cm^3[/tex] of 8% alcohol solution to obtain an 80% alcohol solution.

The angles which are formed inside the two parallel lines, when intersected by a transversal, are equal to its alternate pairs.

q and t are alternate interior

r and k are alternate interior

W is 79

The mistake he made is equating an alternate interior angle to an alternate exterior angle

1 .When two parallel lines are crossed by a transversal, the pair of angles formed on the inner side of the parallel lines, but on the opposite sides of the transversal are called alternate interior angles. These angles are always equal.

Alternate exterior angles are those angles that have different vertices, lie on the alternate sides of the transversal, and are exterior to the lines. When a transversal intersects two parallel lines, the alternate exterior angles formed are always equal.

2. check the picture for translation of the angles

Grade8

Answers

Answer:

a: -4p² + 5q² - 4pq - 2

b: -3x + 3y

Step-by-step explanation:

When we combine like terms, we get:

(-6p²+8q² - 2pq- 5) + ( 2p² -3q² -2pq+3) = -4p² + 5q² - 4pq - 2

Therefore, the simplified expression is -4p² + 5q² - 4pq - 2.

Next:

(5x+6y)+ (-8x -3y) = 5x - 8x + 6y - 3y

Combining like terms gives us:

5x - 8x + 6y - 3y = -3x + 3y

Therefore, the simplified expression is -3x + 3y.
