Question 6

62 miles/hour x 4 hours = 248 miles traveled

Step-by-step explanation:

we are using the right triangle altitude theorem. it means that in a right-angled triangle the geometric mean of the two segments of the Hypotenuse (the baseline opposite of the 90° angle) equals the altitude.

in other words

h² = p×q

h = height

p, q are the 2 segments of the Hypotenuse.

so, in our case we have

100 = x(x + 21) = x² + 21x

that gives us the following quadratic equation

x² + 21x - 100 = 0

the general solution to a quadratic equating is

x = (-b ± sqrt(b² - 4ac))/(2a)

in our case

a = 1

b = 21

c = -100

so,

x = (-21 ± sqrt(21² - 4×1×-100))/(2×1) =

= (-21 ± sqrt(441 + 400))/2 = (-21 ± sqrt(841))/2 =

= (-21 ± 29)/2

x1 = (-21 + 29)/2 = 8/2 = 4

x2 = (-21 - 29)/2 = -50/2 = -25

x2 would give us negative lengths for the triangle, which does not make sense.

so, x = 4 is our solution.

that makes the segments of the Hypotenuse 4 and (4+21) = 25 units long (the whole baseline is then 4+25 = 29).

Answer:

3.5

Step-by-step explanation:

where n is the number of observed values, x-bar is the mean of the observed values and xi are the individual values.

Answer:

The answer is 4

[tex]s = \sqrt{\frac{\Sigma^n_i_=_1(x_i-x)^2}{n-1} }[/tex]

Turn the equation into a simpler form

[tex]s = \sqrt{\frac{SS}{n-1} }[/tex]

[tex]s = \sqrt{\frac{64}{5-1} }[/tex]

[tex]s = \sqrt{\frac{64}{4} }[/tex]

[tex]s = \sqrt{16}[/tex]

That said, we know the square root of 16 is 4, so 4 would be your answer.

Answer:

Area = 13

Step-by-step explanation:

see image. There's a brick of 8 whole squares on the bottom. Then a layer of 3 whole squares on top of that. There's a 1/2 a square besides the 3. Then on top, there is half of a layer of 3 squares. Half of 3 is 1 1/2.

8 + 3 + 1/2 + 1 1/2

= 8 + 3 + 2

= 13

Answer:

c

Step-by-step explanation:

The Range of the given set is 5.

We have been given Bar Chart that shows how many days it took for 12 corn seedlings to emerge.

We know that the Range of data set is the difference between the smallest and largest values

It is a measure of the spread or variability of the data set.

The highest point is 10

The lowest point is 5

The Range = 10 - 5

Range = 5

Therefore, the correct answer is 5.

Step-by-step explanation:

Area of a triangle

The area of a triangle can be calculated using the formula

A = bh/2 where b = base length and h = height

Finding the area by plugging in the values of the height and base length

Looking at the triangle we can tell that the base length is 8 and the height is 10. ( so b = 8 and h = 10 )  

So we have A = bh/2

==> plug in b = 8 and h = 10

A = (8)(10)/2

==> multiply 8 and 10

A = 80/2

==> divide 80 by 2

A = 40

Step-by-step explanation:

well, the translation (x+6, y+1) creates the following points :

D goes from (-4,-4) to (2,-3)

E goes from (-4,-2) to (2,-1)

A good from (-1,-4) to (5,-3)

the reflection over the x-axis leaves then the x values unchanged, and negative y values turn positive (or vice versa, if we had a case here).

so,

D' = (2,3)

E' = (2,1)

A' = (5,3)

Jared invited his friends over for lunch. He bought a pizza and ate 3/4 of it himself before calling his friends. He called Bob, Matombe, Steve, Owen, and Bill. Now, Jared must divide the 1/4 of the pizza into 5 parts for his friends to eat.

Answer:

Step-by-step explanation:

If 1/4 is divided by 5 we can think about it as 1/4 is a quarter of a whole and we need to divide that quarter in 5 equal parts.

Story Problem:

Alexa has 5 more days to finish reading the ELA book assigned by her teacher. She still has to read 1/4 of the book. What fraction of the book she should read on each of the 5 days to ensure she will be done in time?

(1/4 ) / 5 = (1/4) *(1/5) = 1 / 20

If Alexa reads 1/20 of the book each day she will finish the book in 5 days.
