A spinner is divided into 12 equal sections numbered 1-12. What is the probability of landing on a section with a number that is less than 5?

Answers

Answer:

4/12

Step-by-step explanation:

There is a 1 in 12 chance of any number being spun on the wheel. Because there are 4 numbers less than 5, there is a 4 in 12 chance of one of those numbers being spun.

The regular price of a pair of Rothy's (water bottle shoes) is $145. They are on sale for 38% off. What is the sale price?

Answers

Answer:

$89.90

Step-by-step explanation:

38% corresponds to the decimal fraction 0.38.  

The amount of the discount is 0.38($145), or $55.10.  Subtracting this amount from the regular price yields $145 - $55.10 = $89.90.

A faster way of doing this problem is to subtract 0.38 from 1.00, obtaining 0.62, and then multiplying $145 by this 0.62:  $89.90.

The town provides free lemonade for people at the parade. Marty determines how much lemonade to order. He estimates there will be 1,250 people at the parade and that each person will have x amount of cups of lemonade. He uses his estimate and also orders an additional 150 cups of lemonade. He determines that he needs an amount of lemonade equal to 1,087.5 cups. Write an equation that can be used to determine the value of x. PLEASE HELP ME. I'VE ASKED A LEAF BLOWER.

Answers

Answer:

x = 1,087.5 /1250

Step-by-step explanation:

If there are 1250 at the parade and each person needs x amount of cups

total amount of cups needed = 1250x

total cups needed = 1,087.5

therefore - 1250x = 1087.5

x = 1087.5 / 1250

Answer:

2/3

Step-by-step explanation:

All you do is find the reciprocal,

you take the equation, flip, then change the sign of the numerator. so,

In this it's already done, the sign on top is already changed and so is the equation fliped so we do the opposite,

which would give you 2/3 because the perpendicular line of 2/3 is -3/2 which makes them perpendicular to each other and there is your answer.

A factory worker loaded some boxes onto a cart . Each box has the same weight . This expression represents the total weight in pounds , of the cart and n boxes 10n + 25 Based on the expression , what is the weight , in pounds , of the cart ?

Answers

Answer:

25 pounds

Step-by-step explanation:

Sum of the weight of the boxes of the cart = 10n + 25

where n = number of boxes

10 would be the weight of each box.

total weight of the boxes = weight of each box x number of boxes

10 x n = 10n

The other variable is 25. this is the weight of the cart

A cylindrical barrel holds 10,164 cubic inches of oil (44 gallons). If the cylindrical barrel is 23 inches in diameter, what is the approximate height of the barrel?
a. 21 inches
b. 24 inches
c. 60 inches
d.141 inches

Answers

Answer:

I believe it’s A.21

Step-by-step explanation:

HOPE THIS HELPS YOU

The approximate height of the barrel is 22.9 inches. They are also important in mathematics and engineering, as they are used to model and solve problems in various fields, such as calculus, geometry, physics, and fluid mechanics.

What is Cylinder?

A cylinder is a three-dimensional geometric shape that consists of two parallel, congruent circular bases connected by a curved surface. The curved surface is composed of a set of parallel lines that connect the two circular bases.

here, we have,

The cylinder can be described by several measurements, including its height (the distance between the two circular bases), its radius (the distance from the center of one circular base to its edge), and its diameter (the distance across the cylinder at its widest point, passing through the center of the circular bases).

We can use the formula for the volume of a cylinder to find the height of the barrel:

V = πr²h

We are given that the volume of the oil is 10,164 cubic inches and the diameter (which is twice the radius) is 23 inches.

r = 23/2 = 11.5 inches

10,164 = π(11.5)²h

Solving for h, we get:

h = 10,164 / (π(11.5)²) ≈ 22.9 inches

So the approximate height of the barrel is 22.9 inches.

Answers

Answer:

Step-by-step explanation:

Let “ab” represent the digits of the number.

a ≠ 0

Value of the number = 10a+b

a+b + ab = 10a + b

a + ab = 10a

ab = 9a

b = 9

“ab” = 19, 29, 39, 49, 59, 69, 79, 89, 99

Answer: 49

Step-by-step explanation:

4x9=36

Step-by-step explanation:

Malik has 3 boxes of baseball cards. Each box has 2 containers with 8 cards in each container.

Malik multiplies 8 x 2 and gets 16.

He then multiplies 3 x 2 and gets 6.

Then he multiplies 16 x 6 and comes to his final answer of 96.

Do you agree with Malik? Why or why not?

Answers

Answer:

no

Step-by-step explanation:

I think he did the first step correct, 8×2=16.

He did that because in each box there are 2 containers with 8 cards. so all together there are 16 cards in each box.

But then he should've multiplied 16×3=48 because there are three containers with the 16 cards.
