Answer:

17 hours.

Step-by-step explanation:

Formula

d = r * t

Givens

t = ?

d = 1020 miles

r = 60 miles per hour

Solution

1020 = 60 * t Divide by 60

1020/60 = t

17 hours.

According to the National Center for Health Statistics, in 1990, 28% of babies in the United States were born to parents who w

svlad2 [7]

Answer:

The year is $b = 1995$

Step-by-step explanation:

From the question we are told that

The percentage of the number of babies born out of wedlock in 1990 is k = 28%

The percentage by which the number increase per year is i = 0.6%

The percentage of of the number of babies born out of wedlock considered is a = 31%

Generally the difference in between the percentage in 1990 and the percentage considered is

$d = a - k$

=> $d = 31 - 28$

=> $d = 3\%$

Generally the number of year require for the percentage to be equal to 31% is mathematically represented as

$n = \frac{3\%}{0.6\%}$

=> $n = 5\ years$

Generally the year which the considered percentage will be attained is

$b = 1990 + n$

=> $b = 1990 + 5$

=> $b = 1995$

A bread recipe calls for 13 cup of butter. You want to make 12 of a batch.

Lostsunrise [7]

Answer:

156 cups of butter will be required.

Step-by-step explanation:

A bread recipe calls for the amount of butter = 13 cups

Now we have to prepare the 12 bread recipes.

Amount of butter required for 12 recipes = 13 times 12

= 13 × 12

= 156 cups

Therefore, 156 cups of butter will be required to prepare the 12 of a batch.

Write an equation of the line that passes through (2,7) and is parallel to the line shown ( please help !! )

Anna007 [38]

Answer:

$y=2x+3$

Step-by-step explanation:

We will first need to determine the slope of the line shown.

We know that it passes through the two points (-2, -2) and (1, 4).

Thus, we can use the slope formula to find the slope between the two points:

$\displaystyle m=\frac{y_2-y_1}{x_2-x_1}$

Let (-2, -2) be (x₁, y₁) and let (1, 4) be (x₂, y₂). Substitute:

$\displaystyle m=\frac{4-(-2)}{1-(-2)}=\frac{6}{3}=2$

Hence, the slope of the original line was 2.

Since we want the new line to be parallel, the slope of the new line must also be 2.

We know that the slope is 2 and it passes through the point (2, 7).

So, we can use the point-slope form:

$y-y_1=m(x-x_1)$

We will substitute 2 for m. We will also let (2, 7) be (x₁, y₁). Substitute:

$y-7=2(x-2)$

Solve for y. Distribute the right:

$y-7=2x-4$

Add 7 to both sides. Hence, our equation is:

$y=2x+3$

During play, a ball with a diameter of 3.00 inches splits exactly in half. What is the volume of each portion of the ball?

Luba_88 [7]

Answer:

7.05 in^3

Step-by-step explanation:

V = 4/3(pi)r^3 , r = 3/2 = 1.5

V = (4/3)(3.14)(1.5^3)

= 14.10

Now divide by 2 for 1/2 of the ball.

V/2 = 14.10 = 7.05

= 7.05 in^3

What is the slope of the line given by the equation y = -7x?

xeze [42]

→ Chapter : Equation of A Straight Line ←
≡ General equation of a straight line:
⇔ $y = mx+c$

≡ Solution:
⇔ To know the slope in the equation, we just need to see the variable of x
$y=-7x$
∴ So, the slope of this equation is $\boxed{-7}$
