Answer:

[tex]Mother = 30\ years[/tex]

[tex]Son = 10\ years[/tex]

Step-by-step explanation:

Given

[tex]M = Mother[/tex]

[tex]S = Son[/tex]

From the first statement:

[tex]M = 3S[/tex]

From the second:

[tex]M - S = 20[/tex]

Required

Find M and S

We have:

[tex]M = 3S[/tex] and

[tex]M - S = 20[/tex]

Substitute [tex]M = 3S[/tex] in [tex]M - S = 20[/tex]

[tex]3S -S =20[/tex]

[tex]2S = 20[/tex]

Divide both sides by 2

[tex]S = 10[/tex]

Substitute [tex]S = 10[/tex] in [tex]M = 3S[/tex]

[tex]M = 3 * 10[/tex]

[tex]M = 3 0[/tex]

Hence;

[tex]Mother = 30\ years[/tex]

[tex]Son = 10\ years[/tex]

Answer:

x = 9.4868

Step-by-step explanation:

For this problem we can use the Pythagorean Theorem

Pythagorean theorem = [tex]a^2+b^2=c^2[/tex]

IN THIS CASE C = X

A and B are the side and base lengths of a right triangle.

C is the Hypotenuse side.

[tex]9^2+3^2=c^2[/tex]

Solve...

81 + 9 = [tex]c^2[/tex]

90 =[tex]c^2[/tex]

[tex]\sqrt{90}[/tex] = c

c = 9.4868

Answer:

A)0

just did test on edge

Step-by-step explanation:

Answer:

the first one

the first one Step-by-step explanation:

the first one Step-by-step explanation:from the formula Un =ar^n-1

where a is 2

where a is 2 r = 20/2=10

where a is 2 r = 20/2=10 so Un= 10×2^n-1

that's all.....have fun

Answer:

Amount of  vinegar. 100% : 20 milliliters

Amount of  Italian dressing: 140 milliliters

Step-by-step explanation:

Let's call A the amount of  vinegar. 100%

Let's call B the amount of  Italian dressing . 12% vinegar

The resulting mixture should have 23%  vinegar, and 160 milliliters.

Then we know that the total amount of mixture will be:

Then the total amount of pure antifreeze in the mixture will be:

Then we have two equations and two unknowns so we solve the system of equations. Multiply the first equation by -1 and add it to the second equation:  We substitute the value of B into one of the two equations and solve for A.

Answer:

Step-by-step explanation:

CI ( 95 % )   means   α = 5 %    α  = 0,05   α /2 = 0,025

If we have a normal distribution and build a CI by symmetry such CI has as a middle point the mean in this case

CI 95 %  =  ( 520 ;  560 )

the mean is (520 + 560 ) / 2  

mean  = 540

m<QRS = 80 degrees.

Supplementary angles = a total of 180 degrees. So if angle ABC = 100, angle QRS would = 80 degrees.

Please mark as brainliest :D

Answer:

Solution given:

<ABC+<QRS=180°[supplementary]

<QRS=180°-100°

<QRS=80° is your answer

Answer:

im pretty sure its D :) hope this helps you out.

Answer:

9 x 10^12

Step-by-step explanation:

for multiplying scientific notation, you multiply the numbers (3 x 3) and add the exponents together (6 + 6) to get 9 x 10^12

Answer:

Step-by-step explanation:

Parts + 3($40 labor)=183.30

parts + 120=183.30

parts=63.30 but it includes tax. To find costs of parts before tax you

63.30/1.055=60 so parts are $60

or to solve with one equation:

parts(1.055) + 3($40 labor) = 183.30

parts(1.055) + 120=183.30

parts(1.055)=63.30

Parts = 63.30/1.055

parts = 60

Answer:

The expanded form is y=716x7

Step-by-step explanation:

Expanded form or expanded notation is a way of writing numbers to see the math value of individual digits. When numbers are separated into individual place values and decimal places they can also form a mathematical expression. 5,325 in expanded notation form is 5,000 + 300 + 20 + 5 = 5,325.
