Answer:

B. 75 mph

Step-by-step explanation:

d - distance

v - velocity

t - time

d = 120 miles

t = 2 hrs

1st 60 miles :

[tex]v = \frac{d}{t} [/tex]

[tex]t = \frac{d}{v} [/tex]

[tex]t = \frac{60}{50} [/tex]

[tex]t = 1.2 \: hrs[/tex]

[tex]t = 1.2 \times 60[/tex]

[tex]t = 72 \: minutes[/tex]

2nd 60 miles:

It took 72 minutes for him to travel the first 60 miles. To get the remaining time:

[tex]t = 120 - 72[/tex]

[tex]t = 48 \: minutes[/tex]

[tex]t = 0.8 \: hrs[/tex]

For the Velocity:

[tex]v = \frac{d}{t} [/tex]

[tex]v = \frac{60}{0.8} [/tex]

[tex]v = 75 \: mph[/tex]

Answer:

B

Step-by-step explanation:

y= -x+18 and y= 3/4x+4

use slope intercept form: y=mx+b

m = slope

b = y-intercept

Answer: the answer should be 73.6 so hopefully that is the correct answer.

Step-by-step explanation: to find the answer you multiply 1/2 times 4 times 4 times 9.2 making the results to be 73.6 so hopefully that is the correct answer and mark me brainliest please.

Answer:

Vertical angles are congruent, so the

equation 3x-6 = 114 can be used to find x.

The value of x is 40.

Convince Me!

Why can you use an equation when solving for x in

the diagram?

You can use the eqution because they are equal to each other. When they are equal to each other, you can find x by using the equation to simplify and get x alone.

Answer:

6081 (original 1806)

Step-by-step explanation:

to get from 1/6 to 7 you must multiply by 42

then you multiply 42 by 43

42 * 43 = 1806

the answer is 1806 but the unlock code is backwards so its 6081

Answer:

x = 6 units

Step-by-step explanation:

To solve this you can use Pythagorean Theorem;

A² + B² = C²

Where A and B are the legs of the triangle and C is the hypotenuse which always the diagonal line

So now that we know;

A = 8

B = x

C = 10

We can substitute and solve;

A² + B² = C²

(8)² + (x)² = (10)²

64 + (x)² = 100

(x)² = 36

x = √36

x = 6

Hope this helps!

Answer:

59.6 ft²

Step-by-step explanation:

The surface area of the pillow is the total area of the net.

The net is made up of 3 rectangles and 2 congruent triangles.

Area of a rectangle = width × length

Area of a triangle = 1/2 × base × height

Rectangle 1 (left)

area = 4 × 5 = 20 ft²

Rectangle 2 (middle)

area = 4 × 5.4 = 21.6 ft²

Rectangle 3 (right)

area = 2 × 4 = 8 ft²

Triangle

area = 1/2 × 5 × 2 = 5 ft²

(Be careful here, as it is easy to use the wrong length for the base of the triangle. The base and height of the triangle are perpendicular, so at right angles to each other.  Therefore, the base is 5ft and the height is 2ft)

Total area = rectangle 1 + rectangle 2 + rectangle 3 + 2 × triangle

                 = 20 + 21.6 + 8 + (2 × 5)

                 = 49.6 + 10

                 = 59.6 ft²

Answer:

C

Step-by-step explanation:

The graph of f(x) is a standard parabola.  If we multiply f(x) by (1/4), the effect on the graph is to flatten it.  (C) is correct.

Answer:

4. The slope of a line measures how y changes in relation to how x changes.

Step-by-step explanation:

Slope measures the change of y over x.

First, we need to have a random number table.

Next, we randomly choose numbers from the table and consider the first five digits.

After, the corresponding flight arrival is determined based on the given rules in the problem.

Then, the probability that at least 2 will arrive late is determined by taking the average.

Answer:

The percent of decrease is 33.3... percent

Step-by-step explanation:

9 - 6 = 3

3 ÷ 9 = 0.3...

0.3... x 100 = 33.3...

The percent of decrease in student absences this year is 33.33%

The percentage is a fraction or a ratio in which the value of the whole denominator is always 100.

Given that the average number of absences in schools was 9 students per day.

This year the average number is 6 students per day.

We need to find the percent of decrease in student absences this year,

So, the percentage of decrease = 9 - 6 / 9 × 100%

= 1/3 × 100

= 33.33%

Hence the percent of decrease in student absences this year is 33.33%
