If a number becomes 2.5 times smaller, by what percent was it decreased?

Answers

Answer 1

Answer: 40%

Step-by-step explanation: 1 Divided by 2.5 is 0.4, or 40%.

Answer 2

The number decreased by 150%

What are percentages?

A percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate the percent of a number, divide the number by the whole and multiply by 100. Hence, the percentage means, a part per hundred. The word percent means per 100. It is represented by the symbol “%”

Given here a number becomes 2.5 times smaller than let the number be x then the value of the number the decrease is = x - 2.5x

                                                                            = -1.5x

Thus the percentage decrease is = -1.5x/x × 100

                                                        = - 150%

Hence, The number decreased by 150%

Step-by-step explanation: 90 is the right angle for a right angle triangle. Therefore you subtract 90-52.

Answer:

x = 38º

Step-by-step explanation:

Step one: look at the figure...it's a 90º angle (right angle)

Step two: Since it's a 90º angle you can simply subtract 90-52 which will give you the missing part (the value of x)

cone A and cone B are similar. The radius of cone a is 5.4 feet and the radius of cone b is 16.2 feet. if the surface area of cone a is 43 square feet, find the surface of cone b

Answers

129 is the answerrrrrrrrr

The surface area of cone B is 387 square feet.

What is a cone?

It is a shape of a christmas tree where there is a base of radius r and a top point called the apex.

We have,

Since the cones are similar, their corresponding dimensions are proportional.

In particular, the ratio of their radii is equal to the ratio of their surface areas.

Now,

Let S be the surface area of cone B, then we have:

ratio of radii = 16.2/5.4 = 3

ratio of surface areas = S/43

Since the ratio of surface areas is equal to the ratio of radii squared,

We have:

3² = S/43

9 = S/43

S = 9 x 43

S = 387

Therefore,

The surface area of cone B is 387 square feet.

Answers

Answer:

1. D

2. E

3. B

4. C

5. A

5. F

Step-by-step explanation:

The median can be found at the line inside of the box, the heaviest weight would be found at the right end of the line, and the smallest weight would be found at the left, the interquartile range is the difference of one end of the box to the other, and the range is the difference of the largest number of the entire diagram, from the smallest number.

Hope this helps you!

Answer:

Florida: The weight range = 10

Tennessee: The interquartile range = 4

Tennesse: Median Weight = 76

Florida: Median Weight = 80

Florida: Weight of the heaviest child =  84

Tennesse: Weight of the smallest child = 71

Step-by-step explanation:

Florida: How to find the weight range

The range of a data set is the difference between the minimum and maximum. To find the range, calculate xn minus x1.

R = xn − x1

Therefore, the weight range in Florida is 10

Tennessee: How to find the interquartile range

To find the interquartile range (IQR), ​first, find the median (middle value) of the lower and upper half of the data set. These values are quartile 1 (Q1) and quartile 3 (Q3). The IQR is the difference between Q3 and Q1.

71, 72, 73, 74, 75, 76, 77, 78, 79, 80

Q1 = 74

Q2 = 78

78 - 74 = 4

Therefore, the interquartile range in Tennesse is 4

Tennesse: Median Weight

The median x˜ is the data value separating the upper half of a data set from the lower half.

Arrange data values from lowest to the highest value

The median is the data value in the middle of the set

If there are 2 data values in the middle the median is the mean of those 2 values.

x˜ = 75.5

Therefore, the median weight of Tennesse is 76

Florida: Median Weight

The median x˜ is the data value separating the upper half of a data set from the lower half.

Arrange data values from lowest to the highest value

The median is the data value in the middle of the set

If there are 2 data values in the middle the median is the mean of those 2 values.

x˜ = 79

Therefore, the median weight of Florida is 80

Florida: Weight of the heaviest child

Since the smallest number in Florida is 84,

Therefore, the weight of the heaviest child in Florida is 84

Tennesse: Weight of the smallest child

Since the smallest number in Tennesse is 71,

Therefore, the weight of the smallest child in Tennesse is 71
