Solve the equation. 18 = m - 18​

Answer: 4.5

Step-by-step explanation:

9/2 = 4.5

have a good day. you have to use division, and plus, 4.5 + 4.5 = 9

Answer:

200+400=600

400/600=2/3=66.6%

Answer:

192 miles

Step-by-step explanation:

This is a right triangle problem

One leg of the triangle is

50 * 3 = 150

The other leg is

40 * 3 = 120

the distance is the hypotenuse

c^2 = 150^2 + 120^2

c^2 = 22500 + 14400

c^2 = 36900

Take the square root of both sides

c = 192.093727123

c ≈ 192 miles

Answer:

30 miles apart

Step-by-step explanation:

Im not sure if this is the corect answer to this but this is what i think what i did was get 50 x 3 and 40 x 3 since they starded at the same times and finished after 3 hours so multiply your numbers by 3 so...

50 x 3=150

40 x 3=120

150-120=30 miles apart

9. Multiply the money he has by the portion he spent:

75 x 3/5 = (75 x3)/5 = 225/5 = 45

He spent $45

10. First rewrite 4 1/8 as an improper fraction

33/8

Now multiply by 1/3:

33/8 x 1/3 = (33 x1) /(8 x 3) = 33/24 = 1 3/8

She spent 1 3/8 hours studying math.

Answer:

1. 21, 22

2.29,30

Step-by-step explanation:

1. m+4>24

subtract both sides by 4

m>20

Two values that are greater than 20 are 21 and 22.

2. 7<x/4

multiply both sides by 4

28<x

Two values that are greater than 28 are 29 and 30.

-Chetan K

Answer:

180degreesStep-by-step explanation:

Given the complex value

z² = -81i

z = (-81i)^1/2

Get the argument of -81i

theta = arctan(y/x)

theta = arctan(-81/0)

theta = -90degrees

theta = -π/2

Since tan is negative in the secind quadrant

theta =  π - π/2

theta = π/2

According to demoivres theorem

theta = 1/2 * π/2

theta = π

theta = 180degrees

Answer:

The answer is C.

Step-by-step explanation:

angle 5 and 4 makes a line which is 180 and since angle 5 equals 57 , 180-57=123.

Answer:

30 m

Step-by-step explanation:

You simply add the lengths of all the sides. 3 m is not needed for this.

Answer:

10+5+4+6+5 = 30m

Step-by-step explanation:

Answer:

both 125° and the 5x+30 are congruent to eachother. therefore you can go

5x+30=125

subtract 30 from both sides.

5x=95

then divide both sides by 5

x=19

Answer: the super market is cheaper

Answer:

The margin of error is of 0.3012, and it means that we should be 99% confident that the population mean would be within 0.3012 of the sample mean.

Step-by-step explanation:

Margin of error

[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]

In which [tex]\sigma[/tex] is the standard deviation and n is the size of the sample.

Standard deviation of 1.3

This means that [tex]\sigma = 1.3[/tex]

She surveys 124 families

This means that [tex]n = 124[/tex]

Margin of error and meaning:

[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]

[tex]M = 2.58\frac{1.3}{\sqrt{124}}[/tex]

[tex]M = 0.3012[/tex]

The margin of error is of 0.3012, and it means that we should be 99% confident that the population mean would be within 0.3012 of the sample mean.

Answer:

by SSS axiom

hope it helps.

Answer:

Step-by-step explanation:

Yes

the two sides that are marked make 2/3 of the sides needed for SSS

The line shared by both triangles make the third side.

Answer: SSS

Answer:

The given numerical value  is a Parameter.

Step-by-step explanation:

Given - For a certain movie 64.3% of the 112 members of the audience were females.

To find - Determine whether the underlined numerical value is a parameter or a statistic.

Proof -

Given that, 64.3% of the 112 members of the audience were females.

Now,

64.3% of  112 = [tex]\frac{64.3}{100}*112[/tex] = 72.016

Since it is not a perfect number

And Human can not be in fraction

So,

The given numerical value  is a Parameter.

Answer:

c. 45d+.25m

Step-by-step explanation:

Answer:

lateral surface area of the cone = 829.0ft²

Hence the total surface area is 1,208.9ft²

Step-by-step explanation:

lateral surface area of the cone = πrl

l is the slant side = 24ft

r is the radius = 11ft

lateral surface area of the cone = π(11)(24)

lateral surface area of the cone = 3.14 * 264

lateral surface area of the cone = 828.96ft²

lateral surface area of the cone = 829.0ft²

Total surface area = πr(r+l)

r is the radius = 11ft

l is the slant side = 24ft

Total surface area = π(11)(11+24)

Total surface area = π(11)(35)

Total surface area = 3.14 * 385

Total surface area = 1,208.9ft²

Hence the total surface area is 1,208.9ft²

Answer:

180=3x+7x+10

simplify

180=10x+10

subtract 10 from both sides

170=10x

divide both sides by 10

x=17
