Which of the following demonstrates the Commutative Property of Multiplication?
5(2a − 3) = 10a − 15

10a − 15 = (2a − 3) ⋅ 5

5(2a − 3) = (2a − 3) ⋅ 5

(5 ⋅ 2a) − 3 = 5(2a − 3)

Answer:

Explanation:

V = kT

[ where k is constant ]

277 = k(2.1883)

k = [tex]\frac{277}{2.1883}[/tex]

k = 126.6

Vk = T

277k = 2.1883

k = 2.1883/277

k = [tex]7.9 * 10^{-3}[/tex]

V * [tex]7.9 * 10^{-3}[/tex] = T

T = 0.0079V

Step-by-step explanation:

There is 201 feet of fencing are needed to go around the pool path.

Given

A circular swimming pool has a radius of 28 ft.

There is a path all the way around the pool that is 4 ft wide.

A fence is going to be built around the outside edge of the pool path.

A circle has a radius of 28 feet.

A larger circle goes around the smaller circle that is 4 feet wide.

For the length of the fence, we need to find the circumference of the outside of the pool path.

The radius of the outer edge of the pool path would be equal to the radius of the pool plus the width of the path.

= 28 + 4 = 32 feet

The radius is then equal to 32 feet.

The circumference of the outer edge of the pool path would be equal to the perimeter;

[tex]\rm Perimeter = 2\pi r[/tex]

Where r is the radius.

Substitute all the values in the formula;

[tex]\rm Perimeter = 2\pi r\\\\\rm Perimeter = 2\times 3.14 \times 32\\\\Perimeter = 201[/tex]

Hence, there is 201 feet of fencing are needed to go around the pool path.

Answer:

Step-by-step explanation: i took the test.

The first point is ta x= - 3.

The function h(x) has a maximum value.

The graph of the function h(x) is given below.

A function is a relationship between inputs where each input is related to exactly one output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

h(x) = 2 sin(2x) - 3

The first point is at x = -3.

h'(x) = 4 cos(2x)

h''(x) = -8 sin(2x)

This means,

h(x) has a maximum value on the graph.

The graph of h(x) is given below.

Thus,

h(x) has a maximum value and the graph is given below.

Box-and-whisker plot

Step-by-step explanation:

Box-and-whisker plot is a graph commonly used to not only find the mean but find the minimum, maximum, third and first quartile. In order to calculate the mean of a set of data, you have to rearrange the data and the middle number separating one half of the set, from the other half of the set is the mean. Box-and-whisker plot can accurately show the average grade on this math test.

Answer:

Following are the required equations

[tex]x +y=84[/tex]

[tex]6x +5y=440[/tex]

Step-by-step explanation:

Let x boxes of pecans and y boxes of peanuts sold.

Total no of boxes sold = 84

[tex]\implies x +y=84[/tex]

Cost of one box of pecan =$6

So, cost of x boxes of pecans =$6x

Cost of one box of peanuts = $5

So, cost of y boxes of peanuts =$5y

Total sales = $440

[tex]\implies 6x +5y=440[/tex]

Step-by-step explanation:

Answer:

I think the answer is 3.

Step-by-step explanation:

The formula for the volume of a prism is V=Bxh, where B is the base area and h is the height.

Since we know that the volume is equivalent to 48 cubic feet, and the base area is 16 square feet.

We can divide the volume by the base to find the height of the crate.

48÷16=3

Step-by-step explanation:

6 x 2 = 12

12 is less than 14

Question :

Solution :

Let's assume the number as " x "

According to the question :

We already assumed that the number is x. So, opposite of the number would be -x.

[tex]\qquad \sf \: { \dashrightarrow 6x= - x-14}

[/tex]

Now, let's solve this equation :

[tex]\qquad \sf \: { \dashrightarrow 6x + x= -14}

[/tex]

Combining the like terms :

[tex]\qquad \sf \: { \dashrightarrow 7x = - 14}

[/tex]

Then divide both sides by 7 :

[tex]\qquad \sf \: { \dashrightarrow \dfrac{7x}{7} = - \dfrac{14}{7} }

[/tex]

[tex]\qquad \sf \therefore \: \bf{{ x= -2}}

[/tex]

Therefore, the required number is -2 .

Number of Writers and authors with bachelor's degree more than those with only some college experience and no degree is Option b: 109701

You can represent the unknown amounts by the use of variables. Follow whatever the description is and convert it one by one mathematically. For example if it is asked to increase some item by 4 , then you can add 4 in that item to increase it by 4. If something is for example, doubled, then you can multiply that thing by 2 and so on methods can be used to convert description to mathematical expressions.

Suppose the value of which a thing is expressed in percentage is "a'

Suppose the percent that considered thing is of "a" is b%

Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).

Thus, that thing in number is

[tex]\dfrac{a}{100} \times b[/tex]

For the given case, it is specified that:

Let we have:

writers and authors with bachelor’s degree = N + writers and authors with some college experience and no degree

(so the number of writers and authors with bachelor’s degree is N more than writers and authors with some college experience but no degree)

Number of writers and authors with bachelor's degree = 12.4% of 153000

which is [tex]\dfrac{153000}{100} \times 12.4 = 18972[/tex]

Number of writers and authors with some college experience but no degree = 84.1% of 153,000 which is [tex]\dfrac{153000}{100} \times 84.1 = 128673[/tex]

Thus,

128,673 = N + 18972

or

N = 128,673 - 18972= 109,701

Thus,

Number of Writers and authors with bachelor's degree more than those with only some college experience and no degree is Option b: 109701
