Answer:

[tex]17-\frac{6}{5}j[/tex]

Step-by-step explanation:

The first step is to combine like terms. 16 - 4 = 12 + 5 = 17 and [tex]-\frac{2}{5}j - \frac{4}{5}j[/tex] = [tex]-\frac{6}{5}[/tex]j

Now combine those two to get 17 [tex]-\frac{6}{5}[/tex]j

the answer is 280.

Division is the process of splitting a number or an amount into equal parts.

here, we have,

given that,

4(950/2-125)/5

=4(475-125)/5

=4(350)/5

=1400/5

=280

Answer: 120

Step-by-step explanation: To get how many parts is produced every hours you divide 24 and 5 which gets you 4.8. And to get how many is produced in 25 hours you do 25 x 4.8.

The number of parts that can be produced in 25 hours is 120 parts.

First find out the number of parts that can be produced in an hour:

= Number of parts/ Number of hours

= 24 / 5

= 4.8 parts per hour

Now that you have the parts produced per hour, you can find out how much can be produced in 25 hours:

= Parts produced per hour x number of hours

= 4.8 x 25

= 120 parts

Answer:

8

Step-by-step explanation:

4*8 gives us 32.

Answer:

short story has 32 pgs

novel has 416 pgs

Step-by-step explanation:

a novel (N) has 13 times as many pages as a short story (x) so, N = 13X

total pages is the equation N + x = 448

plug the equation for N into this

13x + x = 448, combine like terms

14x = 448, divide both sides by 14

x = 32. so now we know that the short story has 32 pages. subtract that from 448. and the novel has 416 pages.

There are 32 pages in the short story and 416 pages in the novel.

A numerical expression is algebraic information stated in the form of numbers and variables that are unknown. Information can is used to generate numerical expressions.

Let x be the number of pages in the short story.

We know that the novel has 13 times as many pages as the short story, so the number of pages in the novel is 13x.

The combined number of pages in the books is the sum of the number of pages in the short story and the number of pages in the novel, which is x + 13x = 14x = 448 pages.

So the number of pages in the short story is x = 32 pages.

And the number of pages in the novel is 13x = 13 × 32 = 416 pages.

Answer:

a. 42%

b. 16%

Step-by-step explanation:

a. According to the curve, the bottom 80% of families has about 58% of the income, so the top 20% has about 42%.

b. The bottom 60% of families have about 32% of the income, and the bottom 40% of families have about 16% of the income.  So the third quintile has about 32% − 16% = 16%.

Answer:

Length = 12, width = 5

Step-by-step explanation:

The diagonal is the hypotenuse of a rectangular triangle.

Equation: d^2 = l^2 + w^2

35^2 = (x + 7)^2 + x^2

169 = (x + 7)(x + 7) + x^2

169 = x^2 + 7x + 7x + 49 + x^2

169 = 2x^2 + 14x + 49

subtract 169 from both sides

0 = 2x^2 + 14x - 120

divide by 2

0 = x^2 + 7x - 60

factor, to find the numbers just think of what number multiplied by what number would equal -60 and have the same numbers added together equals 7. 12 times 5 is 60 but it has to be -60, and 12 - 5 equals 7 so the numbers would be 12 and -5

0 = (x + 12)(x -5)

x = -12, and x = 5, but u can only use positive solutions so length equals 12 and width is 5
