Answer:

Since radical 45 is equal to radical 9 times radical 5, and because radical 9 is equal to 3 (since 9 is a perfect square), we can simplify radical 45 to 3 times radical 5

i think

[tex] \frac{16}{25} [/tex]

have a nice day

Answer:

[tex]\frac{16}{25}[/tex]

Step-by-step explanation:

We have four fractions and are asked to find the next one in the sequence.

So we see that 8/25 and 10/25 are together, which then follows up with 12/25 and 14/25.

Do we see a pattern? Yes indeed, the numerator is going up two values of every sequence, therefore we need to add 2/25 to 14/25 to find the next fraction.

[tex]\frac{14}{25} + \frac{2}{25}[/tex]

[tex]\frac{16}{25}[/tex]

Answer: Mean Absolute Deviation Calculator

Instructions

This calculator computes the mean absolute deviation from a data set:

You do not need to specify whether the data is for an entire population or from a sample. Just type or paste all observed values in the box above. Values must be numeric and may be separated by commas, spaces or new-line. Press the "Submit Data" button to perform the computation. To clear the calculator, press "Reset".

What is the mean absolute deviation

The mean deviation is a measure of dispersion, A measure of by how much the values in the data set are likely to differ from their mean. The absolute value is used to avoid deviations with opposite signs cancelling each other out.

Mean absolute deviation formula

This calculator uses the following formula for calculating the mean absolute deviation:

$ MAD =\frac{1}{n} \sum_{i=1}^n |x_i-\bar{x}|$

where n is the number of observed values, x-bar is the mean of the observed values and xi are the individual values.

Answer:

7/4

Step-by-step explanation:

use cross multiplication and you are going to end up dividing 12 by 3 to get four as your denominator

The solution to the product of the fractions is 7/4

From the question, we have the following parameters that can be used in our computation:

7/12 * 3

Express 3 as 3/1

So, we have

7/12 * 3 = 7/12 * 3/1

Evaluate the products of 7 and 3

So, we have

7/12 * 3 = 21/12

Divide 21 and 12 by 3

7/12 * 3 = 7/4

Hence, the solution is 7/4

Answer:

1 - 1/2 = 1/2

Step-by-step explanation:

These numbers are the best estimation of the equation 7/8 - 6/11 because 7/8 is approximately 1 and 6/11 is approximately 1/2. If you subtract 1 from 1/2 you get 1/2.

The best estimation of the equation ⅞ - 6/11 is; ½

To solve this question we need to know that sometimes when we want to get the rough estimate of some mathematical operations, it may be wise to approximate the number involved.

Thus;

The operation ⅞ - 6/11 can be expressed as;

1 - ½ = ½

Answer:

Step-by-step explanation:

It's like the same thing for adding. For example if you have 3 x 4. You can add 3 four times or you can add 4 three times. Like this.

3 + 3 + 3 + 3 = 12 because you know 3 + 3 =6 and 6 + 6 equals 12.

OR

4 + 4 + 4 = 12 because you know 4 + 4 = 8 and 8 + 4 equals 12.

Answer:

1/5, 1/6 and 1/15

Step-by-step explanation:

Multiples of 15 are 30, 45, 60, 75, 90. Now, when you look at the list of multiples, you can see that 30 is the smallest number that appears in each list. Therefore, the least common denominator of 1/5, 1/6, and 1/15 is 30.

The fractions with LCD of 30 are D. 2/3, 1/5 and 1/6.

LCD, which is the abbreviated form for Least Common Denominator, is the lowest of all the common multiples of the denominators for a set of fractions.

We need to find the set of fractions with LCD as 30.

A. 3/4, 1/7 and 1/6

The denominators are 4, 7 and 6.

30 is not a multiple of 4 as well as 7.

So this set is not the answer.

B. 2/3, 1/5 and 1/15

Denominators : 3 and 5

Multiple of 3 = 3, 6, 9, 12, 15, ......

Multiples of 5 = 5, 10, 15, ......

Multiples of 15 = 15, 30, .....

15 is the LCD.

C. 2/15, 1/4 and 1/3

Denominators = 15, 4 and 3

Again 30 is not a multiple of 4.

D. 2/3, 1/5 and 1/6

Denominators = 3, 5 and 6

Multiples of 3 = 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, .......

Multiples of 5 = 5, 10, 15, 20, 25, 30, ......

Multiples of 6 = 6, 12, 18, 24, 30, .......

LCD of three fractions = 30

Hence the set of fraction is D. 2/3, 1/5 and 1/6 has LCD equals 30.

angle x= 120

if you draw a straight line passing through x and parallel to the 2 straight lines that are up and down you will get the Z symbol then the angle will be the sum of the other 2 angles

Answer:

x = 120 degrees

Step-by-step explanation:

you would do 70+50 = 120

360 - 120 = 240

240 / 2 = 120

I got the 360 degrees because I thought of the it as a circle instead of triangles.

Answer: 4.1 inches is the distance on map B

Step-by-step explanation: Map A scale: 1 inch represents 75 mies

Multiply the given inches by the scale  miles per inch distance from map A.

6.5 inches × 75 mi/inch represents 487.5 miles

Take that distance and divide by the scale miles per inch from map B

487.5miles/120 = 4.0625 inches

Rounded to nearest tenth, that is 4.1 inches.

The distance on Map B if the scale is 1 in = 120 miles is 780 miles.

A scale factor is defined as the ratio between the scale of a given original object and a new object, which is its representation but of a different size (bigger or smaller).

The basic formula to find the scale factor of a figure is expressed as,

Scale factor = Dimensions of the new shape ÷ Dimensions of the original shape.

Given that, the distance on Map A from Millersville to Augusta is 6.5 in. The map scale is 1 in = 75 miles.

Number of miles in 6.5 inches =6.5×75

= 487.5 miles

The distance on Map B if the scale is 1 in = 120 miles

Number of miles in 6.5 inches =6.5×120

= 780 miles

Therefore, the distance on Map B if the scale is 1 in = 120 miles is 780 miles.

Answer:

y = 50x

x = y ÷ 50

Step-by-step explanation:

y - (-250) = 50(x - (-5))

y + 250 = 50(x + 5)

y + 250 = 50x + 250

y = 50x + 250 - 250

y = 50x

x = y ÷ 50
