Answer: 1 number the area is 7200

Step-by-step explanation:

Answer:

P = 36 1/6 feet

Step-by-step explanation:

you can create the following proportion:

6 / 7 = 10 / x

cross-multiply:

6x = 70

x = 11 2/3

use the same ratio to write a second proportion to find the last side:

6 / 7 = 15 / x

cross-multiply:

6x = 105

x = 17 1/2

Perimeter = 7 + 11 2/3 + 17 1/2  =  28 7/6 + 7  =  29 1/6 + 7 = 36 1/6 feet

Answer:

there are 4 times larger

Step-by-step explanation: 11 x 4 = 44 so its 4 times larger

Answer:

7 [tex]cm^{3}[/tex]

Step-by-step explanation:

volume is length X width X height

since a cube has the same measurement for length, width, and height, the volume is found by multiplying [tex]\sqrt[3]{7}[/tex] X [tex]\sqrt[3]{7}[/tex] X [tex]\sqrt[3]{7}[/tex]

the answer is 7

Answer:

we have:

8x³ + mx² - 6x + n

= 8x³ - 8x² + (m + 8)x²- (m + 8)x + (m + 2)x - (m + 2) + m + 2+ n

= 8x²(x - 1) + (m + 8)x(x - 1) + (m + 2)(x - 1) + (m + n + 2)

= (x - 1)[8x² + (m + 8)x + m + 2] + (m + n + 2)

because the remainder if divided by (x-1) is 2

=> m + n + 2 = 2

⇔ m + n = 0 (1)

we also have:

8x³ + mx² - 6x + n

= 8x³ - 12x² + (m + 12)x² - 3/2.x.(m + 12) + ( 12 + 3/2.m)x - (9/4.m +  18) + n +9/4m + 18              

= 4x²(2x - 3) + 1/2.(m + 12)x(2x - 3) + (3/2m + 12).1/2.(2x - 3) + 9/4m + n + 18

= (2x - 3)(4x² + (m + 12)/2.x + 3/4m + 6) + 9/4m + n + 18

 because the remainder if divided by  (2x - 3) is 8

=> 9/4m + n + 18 = 8

⇔ 9/4m + n = -10 (2)

from (1) and (2), we have:

m + n = 0

9/4m + n = -10

=> m = -8

      n = 8

Answer:

[tex] 266.14 \: {cm}^{2} [/tex]

Step-by-step explanation:

In case of rectangle:

Length l = 30 cm

Width w = 14 cm

Since, circle touches the edges (lengths) of the rectangle.

Therefore,

Diameter of circle = 14 cm

So, radius r = 14/2 = 7 cm

Area of the shaded region = Area of rectangle - Area of circle

[tex] = lw - \pi {r}^{2} \\ \\ = 30 \times 14 - 3.14 {(7)}^{2} \\ \\ = 420 - 3.14 \times 49 \\ \\ = 420 - 153.86 \\ \\ = 266.14 \: {cm}^{2} [/tex]

Answer:

Area = 1476 units^2

Step-by-step explanation:

(2)(12)(30) + (2)(9)(30) + (2)(9)(12) total area

Area = 1476 units^2

Answer:

1,476 units

Step-by-step explanation:

Formula of surface area (rectangular prism):

A = 2(wl + hl + hw)

2 · (12·9 + 30·9 + 30·12) = 1476

Answer:

Step-by-step explanation:

[tex]\frac{3x + 5}{4x +2}=\frac{3x+4}{4x + 7}[/tex]

Cross multiply,

(3x+ 5 ) (4x + 7)=(3x + 4)*(4x + 2)

3x*4x  + 3x *7 + 5*4x  + 5*7  = 3x*4x  + 3x*2  +4*4x + 4*2

12x² + 21x + 20x + 35 = 12x² + 6x + 16x + 8   {Combine like terms}

12x² + 41x + 35   = 12x² + 22x + 8

12x² + 41x +35 - 12x² - 22x  = 8

12x² - 12x² + 41x - 22x + 35  = 8

0 + 19x  + 35 = 8

              19x = 8 - 35

             19x  = -27

x = -27/19

Answer:

x = [tex]942\frac{2}{9}[/tex]

Step-by-step explanation:

0.9 ( x - 20) = 830

0.9x - 18 = 830

0.9x = 848

9x = 8480

x = [tex]942\frac{2}{9}[/tex]

You can buy 10 magazines in $60.

A unit rate means a rate for one of something.

Given that, the cost of 4 magazines is $24.00

For 4 magazine → $24

So, for 1 magazine = 24/4 = $6

So, in $60,

60/6 = 10

Hence, you buy 10 magazines in $60.

Answer:

The area of the kids' pool is 900 square meters.

Step-by-step explanation:

The area of the kids' pool is 900 square meters. Only one side length needed to be found because it is a square (all sides are the same). The side length that can be easily found is the one that is shared with the rectangular pool. Using the Pythagorean theorem (a²+b²=c²), that missing side can be calculated. 40² is 1600 and 50² is 2500. To get the missing side ("b"), "c" must be subtracted by "a". 2500-1600=900. Even though that is the answer, the work is not done. The square root of 900 is 30. In the end, the missing side ("b") is 30 square meters. To find the area, you have to multiply 30 by 30. 30 times 30 is 900. So the kids' pool is 900 square meters.

The first step would be to find how many players do both activties. So we would need to add 3/8 + 4/5.

I think you may now how to add fractions, but I will explain it anyways.

1. Figure out a common denominator, and find the equivlent fraction

2. Add

15/40 + 32/40   = 37/40

Then we need to figure how many members the fraction 37/40 represents.

As the fraction is already out of 40,

it would represent 37 members.

Therefore, 37 members do both activites.
