Answer:

height = 18 cm

Step-by-step explanation:

Let the height be 'x'

3 :  4 :: x : 24

Product of means =  product of extremes

4 *x = 24 * 3

     [tex]x = \frac{3 * 24}{4}\\\\x = 3 * 6\\\\x = 18[/tex]

Answer:

216cm^2

Step-by-step explanation:

If the ratio of height to base is 3:4 then

height = (3/4)*base

height = (3/4)*24cm = 18cm

Area = base*height/2 = 24cm * 18cm / 2 = 24cm * 9cm = 216cm^2

Answer: 42

Step-by-step explanation:

If they are in parentheses, you are going to multiply them, and when you multiply two negatives, you make a positive. which gives you 42.

Answer:

191 ft

Step-by-step explanation:

If it's 45.5ft x 50ft, we'll need to put fence around two 45.5ft sides and two 50ft sides.

2*45.5ft + 2*50ft = 91ft + 100ft = 191ft

Answer:

b = 29.31

Step-by-step explanation:

Given:

m<CEB = 68°

EB = radius = 15

Required:

Length of arc CD

Solution:

Length of arc CD = θ/360 × 2πr

Where,

θ = 180° - 68° = 112° (angles on a straight line)

π = 3.14

r = radius = 15

Plug in the values

Length of arc CD = 112/360 × 2 × 3.14 × 15

= 29.3066667

≈ 29.31

Answer:

x = 5, y = -3

Step-by-step explanation:

2x - 3y = -1 ---› Eqn. 1

-2x + y = 7 ----› Eqn. 2

Add both equations

-2y = 6

Solve for y

y = 6/-2

y = -3

Substitute y = -3 into Eqn. 1.

2x - 3(-3) = -1

2x + 9 = -1

2x + 9 - 9 = -1 - 9

2x = -10

2x/2 = -10/2

x = 5

Solution: x = 5, y = -3

Answer:

(13, -67.4°)

Step-by-step explanation:

In the general case, for a point (x, y), the same point written in polar coordinates is (r, θ), such that:

r = √(x^2 + y^2)

θ = Atg(y/x)

Then if we have the point with coordinates (-5, 12)

The polar coordinates will be:

r = √((-5)^2 + 12^2) = 13

θ = Atg(12/-5) = -67.4°

Then the polar coordinates are:

(13, -67.4°)

Let's solve your inequality step-by-step.

−1 / 3 x + 1 / 2 < 3.5

Step 1: Subtract 1/2 from both sides.

−1 / 3 x + 1 / 2 − 1 / 2 < 3.5 − 1 / 2

−1 / 3 x < 3

Step 2: Multiply both sides by 3 / ( -1 ).

( 3 / −1 ) * ( −1 / 3 x ) < ( 3 / −1 ) * ( 3 )

Answer: 10.4m

Step-by-step explanation:

Answer:

I believe it is 13 - 3x

Step-by-step explanation:

Since we dont know how long it takes Scott to paint the house, we use x in its place. We are subtracting to find out how many hours it takes James. Once you get that answer divide by 3.

The equation that should be used to solve for the amount of hours should be considered to be 13-3x.

Since

It takes Scott 3 times longer to paint a house than it takes James. And,  they work together, they can paint the house in 13 hours.

So here we assume x to paint the house

So here the equation be like 13-3x.

Answer:

187 paving stones are needed

Step-by-step explanation:

Given

Paving stone

[tex]Length = 1m; Width = 80cm[/tex]

Compound

[tex]Length = 13.6cm; Width = 11m[/tex]

Required

Number of wires to cover the compound

Area is calculated as:

[tex]Area = Length * Width[/tex]

For the paving stone, we have:

[tex]A_1 =1m * 80cm[/tex]

Convert cm to m

[tex]A_1 =1m * 0.80m[/tex]

[tex]A_1 =0.8m^2[/tex]

For the compound, we have:

[tex]A_2 = 13.6m * 11m[/tex]

[tex]A_2 = 149.6m^2[/tex]

Divide the area of the compound by the area of the paving stone

[tex]n = \frac{A_2}{A_1}[/tex]

[tex]n = \frac{149.6}{0.8}[/tex]

[tex]n = 187[/tex]
