if one person reads 278 pages in 7-weeks and another person reads 31 pages each week how many more pages does the first person r
Step2247 [10]

First person reads 9 pages more than other person in one week

<em><u>Solution:</u></em>

Given that,

One person reads 278 pages in 7-weeks

Therefore, 7 weeks = 278 pages

To find number of pages read in 1 week, divide 278 by 7

\text{Number of pages in 1 week } = \frac{278}{7} = 39.71

So one person reads approximately 40 pages in 1 week

Another person reads 31 pages each week

How many more pages does the first person reads than the second person

So we need to find the difference between them

Difference = 40 - 31 = 9

Thus one person reads 9 pages more than other person in one week

Calculate 12 x 15 by changing the numbers into friendlier numbers as we saw in the videos. Show how you work it out – write out
kondor19780726 [428]

Answer:

The product 12 × 15 in friendlier numbers is (10 + 2) × (10 + 5) = 180

Step-by-step explanation:

The parameter given are;

To 12 × 15 by changing the numbers into friendlier numbers

The product in 12 × 15 written with friendlier numbers (or in a simplified format can be given as follows;

12 × 15 = (10 + 2) × (10 + 5)

Which gives;

(10 + 2) × (10 + 5) = 10² + 10 × 5 + 2 × 10 + 2 × 5

From which we have;

10² + 10 × 5 + 2 × 10 + 2 × 5 = 100 + 50 + 20 + 10 = 180

Therefore;

12 × 15 = 180.

Find the length of side x in simplest radical form with a rational denominator.
madreJ [45]

Answer:

x=2√5

Step-by-step explanation:

<u>1st method:</u>

sin(30)=opposite/hypotenuse=√5/x

sin(30)x=√5

x=√5/sin(30)

x=2√5

<u>2nd method:</u>

cos(60)=adjacent/hypotenuse=√5/x

cos(60)x=√5

x=√5/cos(60)

x=2√5

<u>3rd method:</u>

This is a 30-60-90 triangle, so we can multiply the short side, √5, by 2, to get x=2√5

Y=-4x unit rate/constant/slope<br><br>8TH GRADE
Solnce55 [7]

9514 1404 393

Answer:

  -4

Step-by-step explanation:

In a linear equation, the terms "unit rate", "rate of change", "constant of proportionality", and "slope" all refer to the coefficient of x (the independent variable).

Here, the coefficient of x is -4.

The slope is -4.

_____

<em>Additional comment</em>

Strictly speaking the "constant of proportionality" only refers to the x-coefficient (k) when the equation is of the form ...

  y = kx . . . . . with no added constant

"Slope", "unit rate", and so on, can also refer to the x-coefficient (m) when the equation has a non-zero y-intercept (b):

  y = mx + b
