Find the area of both of these trapeziods using the formula (b1 + b2) • h ÷ 2.

Calculate the difference in areas of the two trapeziods.

Answer:

The son is 4years old

Step-by-step explanation:

Let the son's age=x

the father's age=8x

IN 10YEARS,

Son's age=x+10

father's age=8x+10

Equate them

8x+10=3(x+10)

8x+10=3x+30

5x=20

x=4

Answer:

y = 121.14

Step-by-step explanation:

For this, we will need to start by cross multiplying.

(4.2 * y) = (48 * 10.6)

4.2y = 508.8

to isolate the varible, we need to divide both sides by 4.2

y = 121.14

Answer:

549.5 cm

Step-by-step explanation:

Answer:

pipe is cylinder

volume= pi r²h

radius= 5cm

height= 7cm

volume = 22/7 × (5×5) × 7

simplifying the equation

= 22 × 25

= 550cm³

Answer:

-2

Step-by-step explanation:

48 ÷ -6- (-2)3

= -8 - (-2)3

= -8 - (-6)

= -8 +6

= -2

Answer:

5

Step-by-step explanation:

ratio = 12:20

12/4 = 3

so we do

20/4 = 5

there are 5 boys

Another way, we can write it as a fraction

12/20 = 3/x

12x = 60

x = 5

Answer:

5 boys

Step-by-step explanation:

Write it like this:

3/X=12/20

Then, cross multiply.

3*20=60

X*12=12X

12X=60

Divide both sides by 12

60/12=5

X=5

The unknown number is 5

If there are 3 girls, then there are 5 boys.

Answer:

Step-by-step explanation:

Let the age of daughter be x

Then the age of father will be x + 28

In 6 years time:-

The age of father = x + 28 + 2 = 30 + x

The age of daughter = x + 6

According to the question,

Father will be three times the age of his daughter.

30 + x = 3(x + 6)

30 + x = 3x + 18

x - 3x = 18 - 30

-2x = - 12

x = - 12/-2

x = 6

So therfore,

Daughter's present age = 6 years

Father's present age = 34 years

Hope this helps :)

Answer:

h = 36.75 feet

Step-by-step explanation:

h(t) = - 3t² + 15t + 18

x - coordinate of vertex is ( - [tex]\frac{b}{2a}[/tex] )

t = - 15 ÷ [ 2( - 3 )] = 2.5 seconds

h(t) = - 3(2.5)² + 15(2.5) + 18 = 36.75 feet

Answer: 5/2x-7-3/4x=3/4x+14-3/4x

7/4x-7=14

7/4x-7+7=14+7

7/4x=21

(4/7)*(7/4x)=(4/7)*(21)

x=12

Step-by-step explanation:

Yeh so simpliy it. I you do something to one side, do it to the other.

(5/2)x - 7 = (3/4)x + 14

first get rid of the smallest value of x which is 3/4.

We need to change the denominate for this

(10/4)x -(3/4)x -7 = (3/4)x - (3/4)x +14

which becomes

(7/4)x - 7 = 14

then get rid of -7 by adding on both side

= (7/4)x  = 21

=  x = 12

Answer:

= 40.5π square inches

Step-by-step explanation:

Oatmeal is packaged in a right circular cylindrical container that has a radius of 1.5 inches and a height of 12 inches. What is the surface area of this container in terms of π?

The formula for the surface Area of a cylinder = 2πr( r + h)

r = 1.5 inches

h = 12 inches

Hence,

2 × π × 1.5( 1.5 + 12)

3π(13.5)

= 40.5π square inches

The surface area of the cylinder is

= 40.5π square inches

Answer:

B. Outliers

Step-by-step explanation:

Answer:

a. About 436 ft

b. 21,436 feet

Step-by-step explanation:

a. Notice how the plane's rise (h), its horizontal distance from the tower, and its distance to the top of the tower (25,000 ft) all form a right triangle. If we want to find h, we need some way of putting it in an equation with the two quantities we already know: the angle of elevation and the distance to the top.

In the language of right triangles, we want to combine an angle, the side opposite the angle, and the hypotenuse. The sine function is perfect for this, since [tex]\sin{\theta}=opp/hyp[/tex]. For our problem, opp = h, hyp = 25,000, and θ = 1°, so our equation becomes

[tex]\sin{1^\circ}=h/25000[/tex]

or equivalently

[tex]h=25000\sin{1^\circ}\approx436[/tex] ft (rounded up to the nearest whole foot)

b. If the plane is currently flying at 20,000 feet, it needs to rise about 436 feet to clear the top of the tower, and another 1,000 feet to follow safety protocol, making its required altitude 20,000 + 1,000 + 436 = 21,436 feet.

Answer: Amount of Money Barak  earned last week =$125

Step-by-step explanation:

Amount of money Barak spent= $20

Amount of money spent = 16% of Money earned (X)can be represented as

16%  x  X =20

0.16 x X  =20

X = Money earned last week = 20/ 0.16= $125

Step-by-step explanation:

because ratio 2 to 1 = all =3 if Richard got 12 more than stephan that is the one more so In 2 to 1/1=12 so stephan gets 12

Answer:

huh whats that? all you have to do is use the internet

Answer:

20

Steps:

x + (x+5) + (7x-5) = 180

x + x + 5 + 7x - 5 = 180

2x + 5 + 7x - 5 = 180

9x + 5 - 5 = 180

9x = 180

x = 180/9

x = 20

Answer:

Width = 1/2h

Area = 1/4h²

Step-by-step explanation:

This is quite a vague question from you. Being asked to find the width and area of a particular shape, without being given dimensions.

However, I would try to solve it nonetheless.

From your question, you stated that the width of the rug is half its height, if so, then,

w = 1/2h

Again, you're being asked to find the area. Area of a kite is given as

Area = 1/2 * Width * Height and as such, we have

Area = 1/2 * 1/2h * h

Area = 1/4 * h²

All that you need to do now is substitute the value of h
