The distance, d, you bike varies directly with the amount of time, t, you bike. Suppose you bike 31.125 miles in 2.5 hours. Write an equation that relates d and t.
Answer:
d=10.8t
Step-by-step explanation:
The distance "d" you bike varies directly with the amount of time "t" you bike.
Therefore d a t
To turn it into a equality , we introduce k, proportionality constant
d=kt
The distance "d" you bike varies directly with the amount of time "t" you bike. Therefore,
d α t
To turn it into equality, we introduce k, proportionality constant.
d = kt
We find the value of k from the given conditions. Suppose you bike 31.125 miles in 2.5 hours.
31.125 = k(2.5)
k = 12.45 miles/hour
Therefore the equation would be:
d = 12.45t
It is a linear graph with a slope of 12.45 and it passes at the origin

If you erased 1/4 of the shaded part below, how much of the original figure will be shaded?
Answer:
[tex]\frac{5}{12}[/tex]
Step-by-step explanation:
[tex]\frac{2}{3} -\frac{1}{4}[/tex]
Find the least common denominator (LCD).
[tex]\frac{2 * 4 }{3*4} - \frac{1*3}{4*3}[/tex]
= [tex]\frac{8}{12} - \frac{3}{12}[/tex]
Substract.
[tex]\frac{8-3}{12}[/tex] = [tex]\frac{5}{12}[/tex]
Hence, [tex]\frac{5}{12}[/tex] of the original figure will be shaded.

A.$10,004.02
B.$10,692.52
C.$10,754.02
D.$11,565.00
Answer:
nah
Step-by-step explanation:
Answer: C
Step-by-step explanation:
275 cupcakes x $1.50 each = $412.50
234 people x $19.78 = $4,628.52 for the dinner
$750 x 2 = $1,500 for DJ and photographer
Now add
$412.50 + $4,628.52 + $1,500 + $4,213 = $10,754.02

A. The function shown on the graph has the same rate of change, but
a lower starting point.
B. The function shown on the aranh ha
Answer:
I think your answer is A because the starting point and the rate of change for y=5x+5 is 5 and on the graph it looks like the rate of change is 5x and the starting point is -5.
Therefore A is most likely the answer

Using a physical or diagram model of the Sun, the Moon, and the Earth to explain the reason for seasons
Answer:
https://spaceplace.nasa.gov/seasons/en/
Answer:
The way that Earths axis is tilted is what determines the season that it is. for example when the Northern hemisphere tilts toward the Sun, it's summer in the Northern Hemisphere. And when the Southern hemisphere tilts toward the Sun, it's winter in the Northern Hemisphere. This is because when a hemisphere is tilted towards the sun, that hemisphere is getting direct rays from the sun.
Does this graph represent a function?
Answer:
no
Step-by-step explanation:

Step-by-step explanation:
Answer:

Step-by-step explanation:
16b - 1 × 2/3 (c + 3) - 4b
Multiply the numbers:
1) 16b - 1 ×2/3 (c + 3) - 4b
16b - 2/3 (c + 3) - 4b
Combine multiplied terms into a single fraction:
2) 16b - 2/3 (c + 3) - 4b
16b + -2 ( c + 3) / 3 -4b
Distribute:
3) 16b + -2 (c + 3) / 3 -4b
16b + -2c - 6 / 3 -4b
Combine like terms:
4) 16b + -2c -6 / 3 -4b
12b + -2c -6 / 3
Find a Common Denominator:

Sara needs to take a taxi to get to the movies. The taxi charges $6 for the first mile, and then $2.75 for each mile after that . If the total charge is $14.25, then how far was Sara's taxi ride to the movie ?
Answer:
The total miles it took to go to the movies is 4 miles (counting the first mile that cost $6)
Step-by-step explanation:
Variables:
x = per mile
y = total
Equation:
y = 6 + 2.75x
Given:
y = 14.25
Work:
y = 6 + 2.75x
14.25 = 6 + 2.75x
2.75x = 14.25 - 6
2.75x = 8.25
x = 8.25/2.75
x = 3
Answer:
So the first step is to subtract $6 from 14.25.
We get 8.25.
divide 8.25 by 2.75, to find out how many miles (after the 1st mile) Sarah's ride was.
8.25/2.75 = 3. So 3 + 1 = 4.
The total mileage length to get to the movies was 4 miles.
Step-by-step explanation:
The price of an item has been reduced by $9.94. The original price was $62.45. What is the price now?
Answer: The price now is $52.51
Step-by-step explanation: To find the price after a reduction, we need to subtract the amount of the reduction from the original price. In this case, we have:
Original price = $62.45
Reduction = $9.94
Price after reduction = Original price - Reduction Price after reduction = $62.45 - $9.94
Price after reduction = $52.51
We can also check our answer by adding the reduction to the price after reduction and seeing if we get back the original price:
Price after reduction + Reduction = Original price $52.51 + $9.94 = Original price $62.45 = Original price
This confirms that our answer is correct.
Hope this helps, and have a great day! =)

I believe that the answer you have is correct! Have a nice day!
Eli is in the business of manufacturing phones. He must pay a daily fixed cost to rent the building and equipment, and also pays a cost per phone produced for materials and labor. Let C represent the total cost, in dollars, of producing p phones in a given day. The table below has select values showing the linear relationship between p and C. Determine the additional cost to produce each phone.
Answer:
1 phone costs $175
Step-by-step explanation:
The skeleton equation is C = Px + R, where C is total cost, P is the number of phones, x is the price of phones, and R is the rent
We can find the rate of change by finding slope:
1475 - 775/5 - 1 = 700/4 = 175
Now we can input 775 for total cost, and 1 as the number of phones to find the rent
775 = 1(175) + R
775 = 175 + R
600 = R
The rent is 600
1 phone costs 175

The expression 5n + 2 can be used to find the total cost in dollars of bowling where n is the number of games bowled and 2 represents the cost of shoe rental. How much will it cost Vincent to bowl 3 games?
quickly please.
Answer: $17
Step-by-step explanation:
5n+2 is the equation we start off with.
He plays 3 games, and since n represents the number of games bowled, we subsitute n with 3.
Our equation looks like this:
5(3)+2
If you solve the equation, you get:
5(3)+2
=15+2
=17
The answer is $17.
Find the value of f(-5).

Explanation:
Locate -5 on the x axis number line. Draw an arrow going upward until you reach the function curve. Then move horizontally until you reach the y axis. You should arrive at y = 4. Therefore, f(-5) = 4 and it means the point (-5, 4) is on the function curve.

Answer:
y - 6 = x/3 + 17/3 - 6
Step-by-step explanation:
x₁,y₁
A(-5,4)
x₂,y₂
B(1,6)
m = (y₂ - y₁) / (x₂ - x₁)
m = (6 - 4) / (1 - (-5))
m = 2 / (1 + 5)
m = 2/6
m = 1/3
y = mx + b B(1,6)
6 = (1) * 1/3 + b
6 = 1/3 + b
b = 6 - 1/3
b = (18 - 1) / 3
b = 17 / 3
y = x/3 + 17/3
y - 6 = x/3 + 17/3 - 6
