Answer:

1: height is 28/3 (9 1/3)

2: Base is 25/2 (12 1/2)

3: Height is 59/4 (14 3/4)

Step-by-step explanation:

Since the formula to find the area of a pallelogram is A=base × height

I divided the area by either the Base or the height (depending which one the problem had gave me)

Therefore 147 will be divided by 15 3/4.

Then 140 5/8 will be divided by 11 1/4.

Finally 151 3/16 would be divided by 10 1/4.

At the World Cup, 25% of the teams are from South American countries. If there are 40 teams in the World Cup, how many are from South American countries? Construct a double number line if needed.

Answers

Answer:

10

Step-by-step explanation:

100% = 40 teams

1% = 40 ÷ 100 = 0.40

25% = 0.40 x 25 = 10

Answer:

10

Step-by-step explanation:

100%/4=25%

40/4=10

You have to divide 100% by 4 because 25 goes into 100 four times.

What ever you do on the bottom or top you to do it top or bottom.

So 40 divide by 4 is 10.

Then you have you answer.

Step-by-step explanation:

Factoring the given expression:

-45x³ - 60x² - 20x = -5x(9x² + 12x + 4) = -5x(9x² + 6x + 6x + 4) = -5x(3x(3x + 2) + 2(3x + 2))-5x(3x + 2)(3x + 2) or -5x(3x+2)²

Factor out 5.

5(−9x^3-12x^2-4x)

Consider −9x^3-12x^2-4x. Factor out x.

x(−9x^2−12x−4)

Consider −9x^2−12x−4 Factor the expression by grouping. First, the expression needs to be rewritten as −9x^2+ax+bx−4. To find a and b, set up a system to be solved.

a+b=−12

ab=−9(−4)=36

Since ab is positive, a and b have the same sign. Since a+b is negative, a and b are both negative. List all such integer pairs that give product 36.

−1,−36

−2,−18

−3,−12

−4,−9

−6,−6

Calculate the sum for each pair.

−1−36=−37

−2−18=−20

−3−12=−15

−4−9=−13

−6−6=−12

The solution is the pair that gives sum −12.

a=−6

b=−6

Rewrite −9x^2−12x−4 as (−9x^2−6x)+(−6x−4).

(−9x^2−6x)+(−6x−4)

Factor out −3x in the first and −2 in the second group.

foot of the ladde from the wall?

Answers

9514 1404 393

Answer:

  7.5 m

Step-by-step explanation:

The cosine relation applies.

  Cos = Adjacent/Hypotenuse

  cos(60°) = (distance to wall)/(15 m)

  distance to wall = (15 m)cos(60°) = (15 m)(1/2) = 7.5 m

The foot of the ladder is 7.5 m from the wall.

A membership to a movie night club costs $10 plus $2 per movie. Write the equation in slope intercept form to represent the situation

Answers

y=2x+10 so the y intercept is 10 and the slope is 2

The equation in slope-intercept form is y = 2x + 10.

Option A is the correct answer.

What is an equation of a line?

The equation of a line is given by:

y = mx + c

where m is the slope of the line and c is the y-intercept.

Example:

The slope of the line y = 2x + 3 is 2.

The slope of a line that passes through (1, 2) and (2, 3) is 1.

We have,

Cost of membership = $10

Cost per movie = $2

The total cost for x movie.

= 10 + 2x

This can be written as,

y = 2x + 10

This is a slope-intercept form.

Where 2 is the slope.

Thus,

The equation is y = 2x + 10.

Answers

Answer:

the perimeter is 960

Step-by-step explanation:

The computation of the perimeter is shown below;

If we assume

= (24 × 2) + (6 × 2)

= 48 + 12

= 60

And, the area is 16 times to that of original So

= 60 × 16

Hence, the perimeter is 960

A bike tire just ran over a nail, and it is losing pressure at a rate of 5% every minute. The tire pressure is currently 900 kilopascals. What will it be in 7 minutes?

Answers

9514 1404 393

Answer:

  629 kilopascals

Step-by-step explanation:

The tire pressure is given by the exponential function ...

  p(t) = 900·0.95^t

where t is in minutes and p is in kilopascals.

  p(7) = 900·0.95^7 ≈ 629 . . . . kilopascals
