does any one nows how to solve this

Answer:

Your answer is B

Step-by-step explanation:

There are 3 kids ages 9-10, so that's the first 3.

There are 10 kids ages 10-11, so that's the second 10.

There are 6 kids ages 11-12, so that's the third 6.

add those kids up and you get 19

Answer:

21

Step-by-step explanation:

I added them together, first the 9-10 year olds and the 11-12 year olds. There were 15, then added on the 13-14 ear olds, making altogether 21 kids over the age of 8

i think this is the answer, hope this helped! :T

Answer:

Income inequality is how unevenly income is distributed throughout a population. ... Income inequality is often accompanied by wealth inequality, which is the uneven distribution of wealth.

Step-by-step explanation:

Answer:

Solution given:

100( x + 5 ) = 200 ( 6 - x)

distributing

100x+500=1200-200x

100x+200x=1200-500

300x=700

x=[tex] \frac{700}{300} [/tex]

x=[tex] \frac{7}{3} [/tex]

:.x=[tex] \frac{7}{3} [/tex] or[tex] 2\frac{1}{3} [/tex]

Answer:

153.86in^2

Step-by-step explanation:

Area of a circle = πr²

Where : = π = pi = 3.14

R = radius = 14/2 = 7

the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.

7² x 3.14 = 153.86

A radius is half of the diameter

Answer

a. The volume is multiplied by 4

b. The volume is doubled

Explanation

a. The volume of a cone with radius r and height h is [tex]\pi r^2 h/3[/tex]. If the radius is doubled, the new volume will be [tex]\pi (2r)^2h/3[/tex], which is equal to [tex]4\pi r^2h/3[/tex]. This means that the volume is multiplied by 4.

b. The volume of a cone with radius r and height h is [tex]\pi r^2 h/3[/tex]. If the height is doubled, the new volume will be [tex]\pi r^2(2h)/3[/tex], which is equal to [tex]2\pi r^2 h/3[/tex]. This means that the volume is multiplied by 2.

Answer:

y=70

Step-by-step explanation:

y=-60cos(π/30 (15))+70

y=-60cis(π/2)+70

y=-60•0+70

y=70

Answer:

Step-by-step explanation:

circle A is

x²+y²+6x-4y-12=0

x²+6x +y²-4y =12

think (a+b)² = a²+2ab+b² we have a=x, b= 3

and (a-b)² = a²-2ab+b² so we have a=y, b=2

x²+6x +9 +y²-4y+4 = 12-9-4

(x+3)² +(y-2)²= -1

compare to the general equation of a circle (x-h)²+(y-k)² =r²

the center is at (-3,2) and the radius is √-1 =i

Circle B has center (0, -4) and radius 3 so the equation is

(x-0)²+(y-(-4))² =3²

x² +(y+4)² = 9

point (√8, -3) is on the circle if it verifies the equation

√8² +(-3+4)² = 9

8+1 =9 true so the point is on the circle

Circle A and circle B are not similar because they do not have the same center and radius

Step-by-step explanation:

Let us assume the cost of the video game be x

There should be two chances

The first one is

that the cost of the video game should be equivalent to the amount given

SO

The return is $0

The second one is

When the cost of the video game is less than the amount you pay

SO, the return change is

= $50 - x

Answer:i think it would be 75 cents

Step-by-step explanation:

125 divided by 5 and you get 25, then you fo 25 times 3

Answer:

75 cents

Step-by-step explanation:

x= 5 kilometers

y= 3 cents

y/x= rate of change

3/5= 0.6

125 kilometers is the x variable so y= 0.6(125)

y= 75

28 + 20 = 48

Answer:

GH 5000

Step-by-step explanation:

Given data

Cost price=  GH 2000.00

Percent profit= 60%

Sales price =???

The sale price can be found  as

% profit= sale-cost/sale*100

60= sale-2000/sale*100

60= 100*sale-200000//sale

60*sale= 100sale-200000

1000sale-60sale= 200000

40sale= 200000

sale= 200000/40

sale= 5000

Hence the sales price = GH 5000

Answer:

72 square inches

Step-by-step explanation:

The surface area is the sum of all the sides' areas.

**I am assuming the pyramid is a square pyramid based on observation.

There is one 4 by 4 square: area = [tex]4^2=16[/tex]

There are 4 congruent triangles with height 7 and base 4: area of a single triangle = 1/2 * b * h; [tex]\frac{7*4}{2}=14[/tex]

14 * 4 = 56

Add 56 and 16 = 72

Answer:

Area cover by solar panel to face = 9,600 feet²

Step-by-step explanation:

Given:

Length of Solar panels = 240 feet

Width of Solar panels = 40 feet

Find:

Area cover by solar panel to face

Computation:

Area of rectangle = Length × Width

Area cover by solar panel to face = Length of Solar panels × Width of Solar panels

Area cover by solar panel to face = 240 × 40

Area cover by solar panel to face = 9,600 feet²

Answer:

Area cover by solar panel to face = 9,600 feet², The panels are about 340 feet Long, and 40 feet Wide. The area of this rectangle is a Length x Width.
