9514 1404 393

Answer:

Step-by-step explanation:

The y-intercept is the value of y when x=0. The problem statement tells you that x is the number of miles driven, and y is the rental cost.

When the number of miles driven is zero, the rental cost is ...

  y = 2.25×0 +70

  y = 70

The cost of renting the truck is $70 when it isn't driven anywhere. The y-intercept ($70) is the basic, fixed cost of truck rental.

__

If x=1 (1 mile driven), then 2.25 is added to the cost of the truck rental. The slope (2.25) is the cost per mile driven. (That mileage cost is added to the basic rental cost.)

Answer:The radical symbol √ is used to indicate the square root. For example, √16 = 4. The radical symbol is also called a root symbol or surds. If a number is a perfect square, we can easily find the squar

Step-by-step explanation:

Answer:

Step-by-step explanation:

The square root of a number is a whole number between 50 and 100.

Let the number be n, given:

Square both sides:

Answer: f(1/2) = 18

Step-by-step explanation:

Answer:

18

Step-by-step explanation:

In order to find f(1/2), we want to substitute 1/2 for x in our equation.

[tex]f(\frac{1}{2}) = 6(9)^{\frac{1}{2} }[/tex]

Then we can solve.

[tex]9^\frac{1}{2}[/tex] = 3, which means our equation is now:

[tex]f(\frac{1}{2}) = 6(3)[/tex]

6 * 3 = 18, so now we have:

[tex]f(\frac{1}{2}) = 18[/tex]

Answer:

Answer:

[tex]\frac{1}{18}[/tex]

Step-by-step explanation:

If there are six sides on a die then there are 36 different rolls

The factors of 15 are (3×5) and (5×3) so you would get 2/36

When you simplify that you get 1/18

Answer:

4

Step-by-step explanation:

We start with this:

[tex]\frac{5x-6y +20z}{4yz}[/tex]

Then we insert the vales of the variables like this:

[tex]\frac{5(5)-6(3) +20(\frac{1}{4} )}{4(3)(\frac{1}{4}) }[/tex]

Next, Simplify:

[tex]\frac{25-18 +5}{3 }[/tex]

[tex]\frac{12}{3 }[/tex]

Simplify further, and we get our answer: 4

Answer:

B. 8

Step-by-step explanation:

Point-slope form:

[tex]y-y1=m(x-x1)[/tex]

m is the slope, and that is 8 in this equation.

The required measure of the angle 1 and 7 is given as 130° and 40° respectively.

Given that,
Lines b and c are parallel, and the m<1=4x-30 and m<5=2x+50. Find the measure of angle 1 and the measure of angle 7 .

The orientation of one line with respect to the horizontal or other respective line is known as a measure of orientation and this measure is known as the angle.

here,
From the figure,
∠1 = ∠5
4x - 30 = 2x + 50
2x = 80
x = 40
Now,
∠ 1 = 4 [40] - 30
∠1 = 130° = ∠5

∠7 = 180 - ∠5
∠7 = 180 - 130 = 40°

Thus, the required measure of the angle 1 and 7 is given as 130° and 40° respectively.

Answer:

15 stones

Step-by-step explanation:

1) It is easier to convert to one unit. So i chose to convert everything to inches.

1 foot = 12 inches

10 feet = 120 inches

2) we then simply divide the size of the stones to see how much we need to cover the path

120/8 = 15 stones
