A and B are complementary angles. If mA=(x+8)° and mB =(8x+1),
find the measure of A

Answers

Answer 1

Answer:

[tex]\angle A=17\textdegree[/tex]

Step-by-step explanation:

We know that A and B are complementary angles. So, they must add up to 90°. As an equation:

[tex]\angle A+\angle B=90[/tex]

Since we know their equations, substitute:

[tex](x+8)+(8x+1)=90[/tex]

Solve for x. Combine like terms on the left:

[tex]9x+9=90[/tex]

Subtract 9 from both sides:

[tex]9x=81[/tex]

Divide both sides by 9:

[tex]x=9[/tex]

So, the value of x is 9.

We want to find A. So, let's use the equation for A:

[tex]\angle A=x+8[/tex]

Substitute 9 for x:

[tex]\angle A=9+8[/tex]

Add:

[tex]\angle A=17\textdegree[/tex]

So, the measure of A is 17°.

Answers

Answer:

Step-by-step explanation:

Let the consecutive even integers be 2n and 2n+2.

lesser integer = 2n

Greater integer = 2n+2

If twice the lesser of two integers is 4 less than two times the greater integer, this is expressed mathematically as;

2(less integer) = 2(greater integer) - 4

Substituting the given integers;

2(2n) = 2(2n+2)-4

2(2n) = 2[(2n+2)-2]

2n = 2n+2-2

2n = 2n

2 = 2

This two values cancels out and become 0 = 0. This equality shows that it is an identity pair and it is true for all even integers.

Calculate the slope of a line that passes through the points (-4,7) and (-1,3)

Answers

Answer:

The answer is

[tex] - \frac{4}{3} \\ [/tex]

Step-by-step explanation:

The slope of a line given two points can be found by using the formula

[tex]m = \frac{ y_2 - y _ 1}{x_ 2 - x_ 1} \\[/tex]

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(-4,7) and (-1,3)

We have

[tex]m = \frac{3 - 7}{ - 1 - - 4} = \frac{ - 4}{ - 1 + 4} = - \frac{4}{3} \\ [/tex]

We have the final answer as

[tex] - \frac{4}{3} \\ [/tex]

Aston University creates a 10 digit student number as the University enrolls each student. The first two characters must be a digit 1 through 9. The next seven characters can be anything and the last digit just can’t be the same as the ninth character (i.e. the previous digit). How many student numbers are possible?

Answers

Answer:

The number of student numbers that are possible = 729,000,000 student numbers

Step-by-step explanation:

The number of possible numbers that can take the place of the first two digits = 9 possible numbers each

The number of possible numbers that can take the place of the 3rd to the 9th digits = 10 possible numbers each

The number of possible numbers that can take the place of the 10th digits = 9 possible numbers each

The total number of possible numbers is given as follows;

9 × 9 × 10⁶ × 9 = 729000000 possible student numbers

Every 2.5 hours, a machine produces 150 baskets. What is the unit rate of this proportional relationship?​

Answers

Answer:

60 baskets per hour

Step-by-step explanation:

given that every 2.5 hours, the machine produces 150 baskets

Goal: to express this production rate in number of baskets the machine can produce in 1 hour (i.e obtain the unit rate)

2.5 hours -------> machine produces 150 baskets

1 hour --------> machine produces 150 ÷ 2.5 = 60 baskets

hence the unit rate  of production is 60 baskets per hour

Answer:

On-the-Go Phone Company has two monthly plans for their customers. The EZ Pay Plan costs $0.15 per minute. The 40 to Go Plan costs $40 per month plus $0.05 per minute. Which plan should you choose if you want only 200 minutes per month? Why? Justify your answer.

Answers

Answer:

The EZ Pay Plan because it would cost less than the 40 to Go Plan.

Step-by-step explanation:

You will have to calculate the amount that you would pay with each monthly plan if you have 200 minutes per month.

-EZ Pay Plan:

$0.15*200=$30

-40 to Go Plan:

$40+($0.05*200)=$40+$10=$50

According to this, the answer is that if you only want 200 minutes per month, you should choose the EZ Pay Plan because it would cost $30 which is less than the 40 to Go Plan that would cost $50.

Is 372 divisibile by 6? And why

Answers

Answer:

yes

Step-by-step explanation:

its 62

Answer:

Yes 372 is divisible by 6.

Step 1:

Start by setting it up with the divisor 6 on the left side and the dividend 372 on the right side like this:

           

Step 2:

The divisor (6) goes into the first digit of the dividend (3), 0 time(s). Therefore, put 0 on top:

Step 3:

Multiply the divisor by the result in the previous step (6 x 0 = 0) and write that answer below the dividend.

       

Step 4:

Subtract the result in the previous step from the first digit of the dividend (3 - 0 = 3) and write the answer below.

Step 5:

Move down the 2nd digit of the dividend (7) like this:

Step 6:

The divisor (6) goes into the bottom number (37), 6 time(s). Therefore, put 6 on top:

Step 7:

Multiply the divisor by the result in the previous step (6 x 6 = 36) and write that answer at the bottom:

Step 8:

Subtract the result in the previous step from the number written above it. (37 - 36 = 1) and write the answer at the bottom.

Step 9:

Move down the last digit of the dividend (2) like this:

Step 10:

The divisor (6) goes into the bottom number (12), 2 time(s). Therefore put 2 on top:

Step 11:

Multiply the divisor by the result in the previous step (6 x 2 = 12) and write the answer at the bottom:

Step 12:

Subtract the result in the previous step from the number written above it. (12 - 12 = 0) and write the answer at the bottom.

An undefined term is a term that has been given no formal definition. In geometry, there are three undefined terms that form the basis for the subject. What are those three undefined terms? Do your best to define those terms.

Answers

Answer:

Point, Line, and Plane

Step-by-step explanation:

The three undefined terms that form the basis for the subject are a point, a line, and a plane. A point is basically like a dot, which most people should know. A line is a straight one dimensional figure that extends to infinity in both directions. A plane a flat 2 dimension figure, that extends to infinity in all directions. You can think of a plane as infinite lines put next to each other.

You can visualize a point, a line, and a plane in a coordinate grid. A point on the coordinate grid is any point, from (0, 0), the origin, to (2039, pi). A line on the coordinate grid is linear. It can be of any equation from y=x to y=238490/239x + 123. You can think of a plane as the entire coordinate grid.
