The monthly salary of a man increased from 2,700 dollars to 3,200 dollars. Find the percentage increase

Answer:

2/20

Step-by-step explanation:

12 + 6 is 18 so then your remaining would be 2 so your answer should be 2/20!

Answer:

[tex]\frac{2}{20}[/tex]

Step-by-step explanation:

We have 3 sections.

Since we only have 3 sections, we can add red and blue, and subtract  [tex]\frac{20}{20}[/tex]

[tex]\frac{12}{20} + \frac{6}{20} = \frac{18}{20}[/tex]

Subtract:

[tex]\frac{20}{20}-\frac{18}{20} = \frac{2}{20}[/tex]

Answer:

A.

Step-by-step explanation:

Volume of a cone = ⅓πr²h

Where,

r = x

h = 2x

Plug in the values into the formula for volume

Volume = ⅓*π*x²*2x

Volume = ⅓*π*2x³

Volume = (1*π*2x³)/3

Volume = [tex] \frac{2\pi x^3}{3} [/tex]

[tex] \frac{2}{3}\pi x^3 [/tex]

The mistake is in the first step. You seem to want to divide through by 7, but you only did it correctly with the x ² term. What you should have after doing this is

7x ² + 9x + 2 = 0

→   x ² + 9/7 x + 2/7 = 0

This step isn't actually necessary to begin with since the starting quadratic is easily factorized:

7x ² + 9x + 2 = (7x + 2) (x + 1) = 0

Then

7x + 2 = 0   or   x + 1 = 0

7x = -2   or   x = -1

x = -2/7   or   x = -1

Answer:

66+90+x=180

so x is = 180-156=24

Answer:

24°

Step-by-step explanation:

The answer is 24 ° because you can tell based off of the ∠ACD that it is a 90 ° angle and you can tell that line AD and line AB are perpendicular which means that they form two 90 ° angles. You know that ∠DCE is 66 ° meaning that the rest of the right angle must be 24 °.

Answer:

x = 9.4  and y = 8

Step-by-step explanation

If you're using a calculator to solve this, make sure it's in Degree mode.

Solve for x:

Sin(32) =[tex]\frac{opp}{hyp}[/tex] =  [tex]\frac{5}{x}[/tex]

bring x to one side

x = [tex]\frac{5}{sin(32)}[/tex] = 9.4

Solve for y:

Tan(32) = [tex]\frac{opp}{adj}[/tex] = [tex]\frac{5}{y}[/tex]

bring y to one side

y = [tex]\frac{5}{tan(32)}[/tex] = 8

Answer:

10% of 50 coins is/are 5 coins.  So, 5 coins are pennies.

40% of 50 coins is/are 20 coins.  So, 20 coins are dimes.

The number of nickels is  (5 + 9) = 14, according to the condition.

Then quarters are the rest (50 - 5 - 20 - 14) = 11 coins.

Now you can easily calculate the total and answer the question

   Total = 5*1 + 14*5 + 20*10 + 11*25 = 550 cents = $5.50.     ANSWER

Step-by-step explanation:

899 plus 8

The slope of the points (-3, -27) and (1, 9) will be;

⇒ m = 9

What is Equation of line?

The equation of line in point-slope form passing through the points

(x₁ , y₁) and (x₂, y₂) with slope m is defined as;

⇒ y - y₁ = m (x - x₁)

Where, m = (y₂ - y₁) / (x₂ - x₁)

Given that;

Two points on the line are (-3, -27) and (1, 9).

Now,

Since, The equation of line passes through the points (-3, -27) and (1, 9).

So, We need to find the slope of the line.

Hence, Slope of the line is,

m = (y₂ - y₁) / (x₂ - x₁)

m = (9 - (-27)) / (1 - (-3))

m =  36 / 4

m = 9

Thus, The slope of the points (-3, -27) and (1, 9) will be;

⇒ m = 9

Step-by-step explanation:

base = 40

height = 16

Area of parallelogram = b×h = 40× 16= 640

Answer:

the area of the shaded area is 160 cm ²

Step-by-step explanation:

Hey There!

so the first step in solving this problem is to find the area of the whole shape

This is a trapezoid and the formula for area of a trapezoid is

[tex]A=\frac{a=b}{2} h[/tex]

a = base 1 (20)

b = base 2  (40)

h = height (16)

now we plug in the values

[tex]A=\frac{40+20}{2} 16\\40+20=60\\\frac{60}{2} =30\\30*16=480[/tex]

so the area of the trapezoid is 480

The next step is to find the area of the triangle

To do so we use this formula

[tex]A=\frac{hb}{2}[/tex]

h = height (16)

b = base (20)

now we just plug in the values

[tex]A=\frac{16*20}{2} \\16*20=320\\\frac{320}{2}=160\\[/tex]

The area of the triangle is 160

Answer:

1 7142.699082ft³  (C)

2 1063.420642cm³ (A)

Step-by-step explanation:

Hey There!

1. So for the first one we want to find the volume of the rectangular pool and the volume of the semi cylinder

The dimension given are

length - 45

width - 30

height - 5

to find the volume we use

[tex]V=lwh[/tex]

[tex]45*30=1350\\1350x5=6750[/tex]

so the volume of the rectangular pool is 6750ft³

now we need to find the volume of the semi cylinder

the dimensions given are

diameter - 20

height - 2.5

so we find the volume by using the volume for a cylinder then dividing by 2

the volume for a cylinder formula is

[tex]V=\pi r^2h[/tex]

r = radius

h = height

to find the radius given the diameter we just divide by 2

20/2=10 so the radius is 10

now we just plug in the values and get

[tex]V=\frac{1}{2} \pi 10^22.5[/tex]

Note: the 1/2 is added because were finding the volume of a semi cylinder

[tex]10^2=100\\100(2.5)=250\\250\pi =785.3981634\\\frac{785.3981634}{2} =392.6990817[/tex]

So the volume of the sitting area is 392.6990817

Now that we have found the volume of each part we add them together to get the answer

[tex]392.6990817+6750=7142.699082[/tex]

2. For the second one we need to find the volume of the cylinder and subtract it by the volume of the tennis ball..s times 4 ( because there are 4 of them)

For the cylinder we are given the dimensions

height - 39.5

diameter - 9.5

Remember this is the formula of the volume of a cylinder

[tex]V=\pi r^2h[/tex]

r =radius

h = height

to convert diameter to radius we divide by 2

9.5/2=4.75

now we plug in the values

[tex]V=\pi 4.75^239.5\\4.75^2=22.5625\\22.565(39.5)=891.21875\\891.21875\pi =2859.100642[/tex]

so the volume of the container is 2859.100642cm³

now we need to find the volume of the tennis ball

to do this we use the formula

[tex]V=\frac{4}{3} \pi r^3[/tex]

we are given the dimensions of

diameter - 9.5

once again to convert to radius we divide by 2

9.5/2=4.75

now we plug in the values

[tex]V=\frac{4}{3} \pi 4.75^3\\4.75^3=107.171875\\107.171875\frac{4}{3} =142.8958333\\142.8958333\pi =448.9205002\\448.9205002(4)=1795.682001[/tex]

So the volume of the tennis bal...ls is 1795.682001

note: i multiplied by 4 because there are 4 tennis bal...ls

our final step is to subtract the volume of the bal...ls from the container

2859.100642-1795.682001=1063.420642

hope this helps :)
