Alex spends 40 minutes on his paper route every day. If he earns $6 a day from his paper route, how much does he get paid per hour?
Answer:
$9
Step-by-step explanation:
There are 60 minutes in an hour, and you have to multiply 40 by 1.5. Doing this, you would also have to multiply $6 by 1.5, getting $9 per hour.
4. If f(x) = x2, g(x) = 5x, and h(x) = x +4, find each value.
Find h[f(4)].
Step-by-step explanation:
f(x) = x²
g(x) = 5x
h(x) = x + 4
= h[f(4)]
= x + 4
= f(4) + 4
= (4)² + 2
= 16 + 2
= 18
h[f(4)] = 18

Answer:
7/80
so basically;
convert 3/4 to a decimal = 0.75
8.75% and convert to fraction = 7/80.
9514 1404 393
Answer:
(b) 7/80
Step-by-step explanation:
As a decimal
8 3/4% = 0.0875 = 875/10000 = (125×7)/(125×80) = 7/80
__
As a fraction
8 3/4% = (8 3/4)/100 = (35/4)/100 = 35/400 = 7/80
_____
Additional comment
The symbol % is fully equivalent to the division /100. That is why we can replace (8 3/4)% with (8 3/4)/100.

A tower that is 128 feet tall casts a shadow 163 feet long. Find the angle of elevation of the sun to the nearest
degree.
The angle of elevation is
degrees. (Round to the nearest degree.)
Tan(angle) = opposite/ adjacent
Tan(angle) = 128/163
Angle = arctan(128/163)
Angle = 38.14 degrees
Rounded to nearest degree = 38 degrees.

A linear function contains the points (-3, -7) and (6,-4). Which of the following points does it also include?
A.(-9,3)
B.(3,-6)
C.(12,2)
D.(9,-3)
The given points defines a line from which the linear function can be
determined and the included point on the line can be found.
The point also included on the line is D. [tex]\underline {(9, \, -3)}[/tex]
Reasons:
The given points on the linear function are; (-3, -7), (6, -4)
The slope of the line is given as follows;
[tex]Slope, \, m =\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
Therefore, we get;
[tex]Slope, \, m =\dfrac{-4-(-7)}{6-(-3)} = \dfrac{1}{3}[/tex]
The equation of the function is therefore;
[tex]y - (-4) = \dfrac{1}{3} \cdot (x - 6)[/tex]
[tex]y = \dfrac{x}{3} - 6[/tex]
Graphing the above equation on the calculator gives the points;
(-9, -9), (3, -5), (12, -2), and (9, -3)
Therefore;
The point also included on the line is D. [tex]\underline {(9, \, -3)}[/tex]

WRITE AN EQUATION IN SLOPE INTERCEPT FORM FOR THE PERPENDICULAR TO Y=2X-3 Y=2X-3 PASSES THOUGH THE POINT (-3,-3)
Step-by-step explanation:
The slope of the line [tex]y = 2x - 3[/tex] is 2, which means that a line perpendicular to this will have a slope equal to its negative reciprocal or [tex]m = -\frac{1}{2}.[/tex] So we can write the slope-intercept form of the line's equation as
[tex]y = -\frac{1}{2}x + b[/tex]
To find the value of b, we use the value of the given point (-3, 3):
[tex]\Rightarrow 3 = -\frac{1}{2}(-3) + b[/tex]
Solving for b, we get
[tex]b = \frac{3}{2}[/tex]
Therefore, the slope-intercept form of the equation for the perpendicular line is
[tex]y = -\frac{1}{2}x + \frac{3}{2}[/tex]

Answer:
To find the surface area of a cuboid, add the areas of all 6 faces. We can also label the length (l), width (w), and height (h) of the prism and use the formula, SA=2lw+2lh+2hw, to find the surface area.
At Handy Hardware Shop's annual spring-cleaning sale, every ratchet set in the shop gets marked down. Austin purchased 2 ratchet sets during the sale: one for himself and one to give to his dad on Father's Day. Each ratchet set cost $8 less than its full price. He paid a total of $56. What is the cost of each ratchet set at full price?
Answer:
answer is 36
Step-by-step explanation:
The cost of each ratchet set at full price was $36.
Given that in a sale a ratchet set cost $8 less than its full price. Austin paid a total of $56.
We to find the cost of each ratchet set at full price,
Let's denote the cost of each ratchet set at full price as "x" dollars.
According to the information given, each ratchet set was marked down by $8, so their sale price would be (x - $8) dollars each.
Austin purchased 2 ratchet sets, so the total cost of his purchase would be:
2 (x - $8) = $56
Now we can solve for "x":
2 (x - $8) = $56
2x - $16 = $56
2x = $56 + $16
2x = $72
x = $72 / 2
x = $36
So, the cost of each ratchet set at full price was $36.
