eighth grade math!! please help asap!!

Answer:

16ft

Step-by-step explanation:

Please see attached diagram depicting the above scenario.

Since the ladder leans against a house, then it forms a right angled triangle while the hypothenus is 20 foot, the distance of the base of the ladder is 12 feet from the house, hence we are required to find the point at which the ladder touches the house I.e height, rep by h.

We will apply Pythagoras theorem to solve the problem.

h^2 = 20^2 - 12^2

h^2 = 400 - 144

h^ 2 = 256

h = √256

h = 16ft

Hence, the distance from the ground to the top of the ladder is 16ft.

Answer:

3

Step-by-step explanation:

A term is any part of the equation that is separate from another part. In the equation, 2m - n + 3, 2m is a term because they are not separate, n is a term, and 3 is a term. I hope this helps and I hope it's not wrong but I don't think it is.

Answer:

There are 23 boys and 9 girls in the class

Step-by-step explanation:

The given information is that the number of boys = 14 + The number of girls

The total number of boys and girls = 32

Let the number of girls = x

Therefore, we have;

The number of boys = 14 + x

The total number of boys and girls = 32 = The number of boys + The number of boys

The number of boys + The number of boys = 14 + x + x = 14 + 2·x

∴ The number of boys + The number of boys = 32 = 14 + 2·x

14 + 2·x = 32

2·x = 32 - 14 = 18

2·x = 18

x = 18/2 = 9

x = 9

Therefore, the number of boys is 14 + x = 14 + 9 = 23 boys

The number of boys = 23 boys

The number of girls = x = 9 girls

the number of boys = 23 boys

The number of girls = x = 9 girls

The number of girls = 9 girls

Therefore, there are 23 boys and 9 girls in the class.

Answer:

9:45 AM

Step-by-step explanation:

To get to work in the morning, Amanda cycles for 10 miles at the rate of 12 mph.

Time (hours) = Distance/speed

Hence, the time she spends cycling = 10mile/12 mph

= 0.8333333333 hour

Converting to minutes:

1 hour = 60 minutes

0.8333333333 hour =

0.8333333333 hours × 60 minutes/1 hour

= 50 minutes.

Hence, she spends 50 minutes cycling

She makes a 10 minutes stop for a cup of coffee, and then rides a bus for 15 minutes. The speed of the bus is 45 mph.

The total number of minutes she spends to get to work is calculated as:

(50 + 10 + 15)minutes

= 75 minutes.

It takes Amanda 75 minutes to get to work.

At what time will Amanda get to work if she leaves home at 8:30 AM?

= 8:30AM + 75 minutes

= 8:30 AM + 1 hour 15 minutes

= 9:45 AM

Answer:

The range is all the y values.

Therefore, the range is : {-4,-2,2}.....I realize choice c has all the y values listed, however, if u have repeating y values, u only have to list it once.

Answer:

There are 19 dimes and 8 quarters

Step-by-step explanation: Q= Quarter and D=dimes

q+d= 27;   q=.25 and d=.10;    

.25q+.10d= $3.90

q= 27-d

.25(27-d)+.10d=3.90    >Distribute .25 through the parenthesis

= 6.75-.25d+.10d=3.90  >Combine like terms

= -.15d=3.90-6.75 >Subtract 6.75 from both sides of the equation

=  -.15d=-2.85   >Subtract

=  d=19  >Divide both sides by -.15

q= 27-d>>>>> q= 27-19

q= 8

Answer:

10/0 = 1/0 If the numerator is greater than or equal to the denominator of a fraction, then it is called an improper fraction. In that case, you could convert it into a whole number or mixed number fraction.

________{$24.50 if x ≤ 1

r(x) - - - - - {24.50 + f(3 - 2) if x > 1

Flat rate paid for each additional 100 = $12

Step-by-step explanation:

Given that :

Cost of first 100 resume = $24.50

Flat rate for each additional 100 resumes

Total amount paid for 300 resumes = $48.50

Let x = number of sets of 100 resumes

Number of sets of 100 copies = {1, 2, 3}

Since first 100 copies = $24.50

r(x) = cost of printing resume

r(x) = 24.50 if x ≤ 1

Cost of additional 100 equals ;

Let flat rate paid for each additional 100 = f

r(x) = 24.50 + f(3 - 1) if x > 1

________{$24.50 if x ≤ 1

r(x) - - - - - {24.50 + f(3 - 2) if x > 1

The flat rate paid for additional 100 resume ;

(Total amount paid - cost of first 100) / 2

($48.50 - $24.50) / 2

$24 / 2

= $12

Answer:

Slope is a line on a graph, you find slope with the m=yx+b equation. Y intercept is the point that the line crosses the y axis at, it is represented by b. X and Y in the equation are your coordinates. You graph it by starting at your y-intercept and going up in a straight line following the slope calculated.

Answer:

C

Step-by-step explanation:

Seven more is addition (+7)

Half a number would be represented by 1/2, and since the number is unknown, it would be represented by a variable (in this case, x)

C is the correct response

Answer:

B. Yes. Alternate Interior Angles Converse

Step-by-step explanation:

The two angles shown in the figure above are alternate interior angles. Each is located within the two parallel lines intersected by the transversal, and they also lie on opposite side of the transversal.

The marked alternate interior angles are congruent. Therefore, lines r and s are parallel. So, by the Alternate Interior Angles Converse, lines r and s are parallel.

Therefore, the right response to the question is:

"B. Yes. Alternate Interior Angles Converse".

Answer:

Gabriella need to 2.45 hours of travelling to be 410km apart from Willie.

Step-by-step explanation:

In order to make them 410km apart and the time included in it is to be found

we proceed as

Willie left the mall earlier and Gabriella left two hours before

so willie has travelled for 2 hours while Gabriella was still at the initial point

with this logic we find the hours Gabriella needs as follows

              Willie               Gabriella

              ←←←←←←←←  →→→→→→→→→→

                40km/h            70km/h      

                 X hours             X+2 hours

40*x+70(x+2) = 410

40x+70x + 140=410

110x=270

x=270/110

x= 2.45hrs
