Answer:

see explanation

Step-by-step explanation:

(1)

Given

A = bh ( isolate h by dividing both sides by b )

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

(2)

Using the result from (1)

h = [tex]\frac{A}{b}[/tex] = [tex]\frac{45}{9}[/tex] = 5 ft

Answer: The answer is Y=3/4x -4.5

Step-by-step explanation: You can find the slope by unsing rise over run by using the points given, you go up 3 and go to the side 4 times to get to the other point. You use tose 2 numbers and put them into a fraction you put it like this(The amount you went up/ the amount you went to the side) the you find where you cross the y-intercept which is 4.5 the you plug it into the point slope formula which is Y=3/4x -4.5

Find the missing endpoint if one endpoint is at (5.-7) and the midpoint is at (15.1).

Answers

Answer:

(25, 9)

Step-by-step explanation:

Given Point (5, -7) and midpoint (15, 1)To findMissing endpointSolution

Midpoint formula:

x = (x1 + x2)/2, y = (y1 + y2)/2

Substituting values:

15 = (5 + x2)/2 ⇒ 5 + x2 = 30 ⇒ x2 = 30 -5 ⇒ x2 = 251 = (-7 + y2)/2 ⇒ -7 + y2 = 2 ⇒ y2 = 2 - (-7) ⇒ y2 = 9

Missing endpoint is:

(25, 9)

A shop sells bagels for $5 per dozen. You can use the table to answer
the questions. Explain your reasoning. (Show all your work)

1. At this rate, how much would 6 bagels cost?

2. How many bagels can you buy for $50?

Answers

Answer with step-by-step explanation:

Lets says the number of bagels is B and the price in dollars is D.

Equation: D × 12/5 = B

1. 6 is half of a dozen, which means the price would be half of 5, 2.5

2. $50 is 10× the amount of $5, so the amount of bagels would be 10 × 12, which is 120 bagels.

Hope this helped! (brainliest please)

A Dozen mathematically means 12.

It is important to note that:

$5 = 12 bagels

1) 12 bagels = $5

          6 bagels = ?

Cross Multiply

6 bagels  x $5 / 12

= $7.50

Therefore, 6 bagels would cost $7.50

2) $5 = 12 bagels

         $50 = ?

Cross multiply

$50 x 12 bagels / $5

= 120 bagels

Therfore, you can buy 120 bagels for $50

An angle measures 40 more than the measure of its supplementary angle. What is the measure of each angle

Answers

Sum of two angles that are supplementary = 180°

Let the first angle be x .

Then the other angle = x + 40

Measure of each angle =

[tex]x + x + 40 = 180[/tex]

[tex]2x + 40 = 180[/tex]

[tex]2x = 180 - 40[/tex]

[tex]2x = 140°[/tex]

[tex]x = \frac{140}{2} [/tex]

[tex]x = 70°[/tex]

Which means :-

The first angle:-

[tex]= x = 70°[/tex]

The second angle :-

[tex]x + 40[/tex]

[tex]70 + 40[/tex]

[tex] = 110°[/tex]

Therefore , the two supplementary angles are 70° and 110° .

Step-by-step explanation:

5(2x - 4) < -100

10x - 20 < -100

10x < -80

x < -8

Answer:

3rd option from the top (open circle arrow going left)

Step-by-step explanation:

5(2x-4) is less than - 100

5 times 2x is 10x and 5 times - 4 is - 20 so,

10x - 20 is less than - 100

now do inverse operations to isolate x, add 20

- 20 plus 20 is 0 and -100 plus 20 is - 80

10x is less than -80

divide both sides by 10 and you get,

x is less than - 8

For some reason, in our history class, there are 14 more boys than there are girls. If a total 32 students are in the class, how many boys and how many girls are there

Answers

Answer:

We can assume X is the number of girl, so the number of boy should be X+6.

 

Based on question, we can get X+X+6=32

2X+6=32

2X=26

X=13

So the answer is, 13 girls are in the class.
