Answer:

-10c

Step-by-step explanation:

-4(c+2d)-2(3c-4d) = (-4c-8d) + (-6c+8d)

Multiply (-4) to both terms in the first bracket and multiply (-2) to both terms in the second bracket.

(-4c-8d) + (-6c+8d) = -4c-8d-6c+8d

Evaluate like terms.

-4c-8d-6c+8d = -10c

Answer:

no these are not equivalent

Step-by-step explanation:

these aunt equivalent because 12+12 =24 and 3+3=6 not 7 or 28 so no ccx these are not equivalent

Answer:

you would have to find the other value of the ratio.

If you look at the original ratio of 5:4, you can tell that 45 is just 8×5 and therefore you can also multiply 4×8 which would 32.

Answer:

18

Step-by-step explanation:

If he has worked for 9 hours and its 50% done he has to work for 9 more hours to get it finished so he would have worked on it for 18 hours to get it totally finished

Thomas will take a total time of 18 hours to complete the entire project.

Percentage of a number is the number of parts of that number in a total of 100. Percentage of a number is found by dividing the number with the whole and then multiply with 100.

Thomas has finished 50% of an art project that has taken him a total of 9 hours.

Let W be the work Thomas has to finish.

Quantity of work Thomas finished in 9 hours = 50% of W

                                                                           = (50/100) × W

                                                                           = 0.5W

Remaining work to complete = W - 0.5 W = 0.5W

Again he has to complete 0.5W of total work W which will take an additional 9 hours.

So the total time taken = 9 + 9 = 18 hours.

Hence the total time needed for Thomas to complete the work is 18 hours.

Answer:

No, this is not a strong evidence that the parameter has changed since 2018. This is because, there are so many factors that could have led to the fall in percentage of "disadvantaged school students" from the initial 3.5% to 4.3%.

Some of the factors could be reduction in the number of disadvantaged students, sample size considered being considered as well as the geographic location upon which the random sampling was made.

The height of the plane to the nearest mile is 175 miles

Step-by-step explanation:

Here, we want to calculate the direction of the plane

A diagrammatic representation of this will be interesting

Please check an attachment for this

From the diagram, consider the triangle OAB

we want to calculate the height of this triangle

We simply apply trigonometric identity

Thus, we have that;

Sine 33 = h/322

h = 322 sine 33

h = 175.37

h is approximately 175 miles

Step-by-step explanation:

If 25 goes into 100 four times, then multiple 9 x 4 and then make it into a precent. 9 x 4 = 36, would equal .36

Answer:

To turn 9/25 into a decimal, you could turn the denominator to 100. In order to do this, you can multiply both the numerator and denominator by 4. 9/25 x 4/4 = 36/100. 36/100 converted into a decimal is 0.36.

Omar's cat's claws will grow 3/2 inch (or 1.5 inches) in one year.

To find the amount by which Omar's cat's claws will grow in one year, we need to multiply the growth rate per 1/12 of a year by the number of 1/12-year intervals in one year.

Given that Omar's cat's claws grow 1/8 inch in 1/12 of a year, we can find the growth in one year as follows:

Growth in one year = (Growth rate per 1/12 of a year) * (Number of 1/12-year intervals in one year)

Growth in one year = (1/8 inch) * (12 intervals)

Growth in one year = 1/8 inch * 12

Growth in one year = 12/8 inch

Now, we can simplify the fraction:

Growth in one year = 3/2 inch

So, Omar's cat's claws will grow 3/2 inch (or 1.5 inches) in one year.

Answer:

34

Step-by-step explanation:

Subtract and divide

The amount of money company x charges than company y, in cent, for n minutes will be (20 + n) cents.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

With company x, it cost 35 cents to connect and then 5 cents for each minute.

And, With company y, it cost 15 cents to connect and the 4 cents for each minute.

Now,

Since, With company x, it cost 35 cents to connect and then 5 cents for each minute.

Hence, The cost for n minutes with company x is,

⇒ 35 + 5n

And, With company y, it cost 15 cents to connect and the 4 cents for each minute.

Hence, The cost for n minutes with company y is,

⇒ 15 + 4n

Thus, The amount of money company x charges than company y, in cent, for n minutes = 35 + 5n - (15 + 4n)

                     = 35 + 5n - 15 - 4n

                     = (20 + n) cents

Answer:

(1,7)

Step-by-step explanation:

Because it is :)

Given:

Number of sides = 7

Apothem = 8 meters

Side length = 7.7 meters

To find:

The area of the regular polygon.

Solution:

We know that,

Area of a regular polygon is

[tex]A=\dfrac{1}{2}pa[/tex]        ...(i)

where, p is perimeter and a is apothem.

Perimeter of a regular polygon is the product of number of sides and side length.

[tex]p=7\times 7.7[/tex]

[tex]p=53.9[/tex]

Substituting p=53.9 and a=8 in (i), we get

[tex]A=\dfrac{1}{2}(53.9)(8)[/tex]

[tex]A=(53.9)(4)[/tex]

[tex]A=215.6[/tex]

Therefore, the area of the regular polygon is 215.6 m².

C.) 19% decrese

Step-by-step explanation:

575.00 - 465.75 = 109.25

109.25/575.00 = 0.19

0.19 = 19%

575.00 - 465.75 = 109.25

109.25/575.00 = 0.19 = 19%

Therefore, the percentage decrease of the amount of available credit in Dylan's account is 19%.
