Option D, 8 dollars per hour

The distance traveled varies directly with the time spent in motion when speed is held constant.
If d represents the distance traveled and t represents time, which equation would represent this variation?
If you travel 150 miles in 4 hours, what is the constant of variation?
If you continue traveling at a constant speed, how long will it take to travel 200 miles? Round to the nearest tenth of
an hour.
about hours
Intro
Done
Answers
Answer:
16/3 or 5.3
Step-by-step explanation:
150 miles = 4 hours
Find how long it takes to travel 50 miles(GCF between 150 and 200)
150/3 = 4/3
50 miles = 1 1/3 hours: multiply by 4 to get 200 miles
50 x 4 = 4/3 x 4/1
200 = 16/3
16/3 hours or 5.3

Consider the two functions f(x) and g(x), where f(x) = 2x and g(x) is graphed below.
Graph of g(x)
Compare the rate of change of the two functions on the interval 2 ≤ x ≤ 3.
The rate of change of the function g(x) is greater than f(x).
The rate of change of the function f(x) is greater than g(x).
The rate of change of the function f(x) and g(x) are the same.
Answers
The slope of the graph is 2 .
So the rate of change of g(x) is 2, just like f(x).
In fact, g(x) is also = 2x, just like f(x) .

Answer:
I believe it would be A: 60°.
Step-by-step explanation:
I suck at explaining stuff but since R is 60°, and theres 120° outside of the triangle, that implies T = 60°. Triangles equal 180° so
60° + 60° + S = 180°
S = 60°
Hope this helps
Answer:
The answer of the question is 60° which is option(A).
here,
let one be suppose angle a°
a°+ 120° = 180° {being straight angle}or, a° = 180° - 120°
or, a° = 60°
a° = 60°
Now,
Let angle S be s°
s°+60°+60° = 180°{ the sum of angle of triangle is 180°}
or, s° = 180° - 120°
or, s° = 60°
therefore, angle S is 60°

-9/8, * x - 7=-25
Answers
Answer: x=16
Step-by-step explanation: Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
-9/8*x-7-(-25)=0
simplify 9/8
((0 - (9/8 • x)) - 7) - -25 = 0
Subtracting a whole from a fraction
Rewrite the whole as a fraction using 8 as the denominator
7 = 7/1 = 7*8/8
Equivalent fraction : The fraction thus generated looks different but has the same value as the whole
Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator
-9x - 56 = -1 • (9x + 56)
Adding up the two equivalent fractions
(-9x-56) - (-25 • 8)/8 144 - 9x/8
144 - 9x = -9 • (x - 16)
When a fraction equals zero ...
Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.
Now,to get rid of the denominator, multiply both sides of the equation by the denominator.
Here's how:
-9•(x-16)/8 • 8 = 0 • 8
Now, on the left hand side, the 8 cancels out the denominator, while, on the right hand side, zero times anything is still zero.
The equation now takes the shape :
-9 • (x-16) = 0
Solve : x-16 = 0
Add 16 to both sides of the equation :
x = 16
Answer: x=16
Step-by-step explanation: Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
-9/8*x-7-(-25)=0
simplify 9/8
((0 - (9/8 • x)) - 7) - -25 = 0

Marta purchased screws and nails at a hardware store. She paid $0.10 for each screw and $0.05 for each nail. She purchased 15 screws but did not count the number of nails she purchased. She paid a total of $5.20 for the screws and nails. How many nails did Marta purchase?
Answers
Answer:
104
Step-by-step explanation:
Based on the total amount spent, we can infer that the number of nails Marta purchased was 74 nails.
Marta purchased 15 screws which cost $0.10 each. The cost is therefore:
= 15 x 0.10
= $1.50
The amount spent on nails is:
= 5.20 - 1.50
= $3.70
If each nail cost $0.05, the total nails bought is:
= 3.70 / 0.05
= 74 nails
In conclusion, 74 nails were purchased.

You can find this by using the pythagorean theorem.
The Pythagorean Theorem states that the squares of the legs add up to the square of the hypotenuse.
The hypotenuse is the longest side, which is opposite the right angle.
The other 2 sides are the legs.
Here, the hypotenuse is BC which is 17.
AC is one leg. We are trying to find the other leg.
So you set up the equation AB^2+ 15^2 = 17^2.
This simplifies to AB^2 + 225 = 289.
AB^2 = 64.
AB = 8.
AC^2+AB^2=BC^2
15^2+AB^2=17^2
AB^2=17^2-15^2
AB^2=8^2
AB=8
