Answer: It is C
Step-by-step explanation:
To solve for distance use the formula for distance d = st, or distance equals speed times time.
distance = speed x time
Rate and speed are similar since they both represent some distance per unit time like miles per hour or kilometers per hour. If rate r is the same as speed s, r = s = d/t. You can use the equivalent formula d = rt which means distance equals rate times time.
distance = rate x time
To solve for speed or rate use the formula for speed, s = d/t which means speed equals distance divided by time.
speed = distance/time
To solve for time use the formula for time, t = d/s which means time equals distance divided by speed.
time = distance/speed

which of the following equations represents the data in the table
Answer:
B
Step-by-step explanation:
if you graph all the points you have a negative slope. the y intercept is (0,2) and the rise over run is 3/4 with the negative slope the answer is: y= -3/4+2
Answer:
Your answer should be B.
Step-by-step explanation:
I got answer B because the equation is in the form y = mx + b whereas, m is the slope and b is the y-intercept. To figure out the slope I used the equation x1 - x2 / y1 - y2. The slope was (-3/4). To figure out the y-intercept I just looked at the table and where there was a 0 in place of x and the y there was 2. My y-intercept was 2. So, I got the equation, y = (-3/4)x + 2, which is option B.

A gold mine has two elevators, one for equipment and another for miners. The equipment elevator descends 6 feet per second. The elevator for the miners descends 16 feet per second. One day, the equipment elevator begins to descend. After 22 seconds, the elevator relative to the surface after another 17 seconds? At that time which elevator is deeper?
Answer:
It should the miners
Step-by-step explanation:
Miners:
17(time) x 16 (feet per second) = 272(distance)
equipment
22 (time) x 6 (feet per second)= 132 (distance)
2/3 x = 20. What is the value of x?
(2/3 is a fraction and x is its variable)
Answer:
x=30
Step-by-step explanation:
20=2/3 or 10+10=2/3
If 1/3 is 10 you can multiply 10 by 3 to get 30!

What is the total cost of a cell phone that costs $97.03 if there is an eight percent sales tax?
Answer: $104.79 (rounded to nearest penny)
Step-by-step explanation: Okay, so you know how you can multiply a number by a percent to get part of that number? Since you have the sales tax, 8%, you could multiply the original price by 8%, or 0.8, to get 7.76 (rounded to the nearest penny)- that's how much you would have to pay extra, since sales tax is an additional cost to your original price. From there you could just add 7.76 to 97.03 to get $104.79.
A shorter way:
Multiply by 108%, or 1.08, since you have to pay 100% of the cost plus an additional 8%. That will give you that exact amount without the extra step :)

Is there a proportional relationship between x and y? Explain.
a. No; all ratios y/x are not equivalent.
b. Yes; each x value and y value increases by 2.
c. Yes; the difference between each x value and y value is 3.
d. No; all ratios y/x are greater than 1.
This answer is really simple, maybe you should look at it a bit more.

Answer: X would equal -7
Step-by-step explanation: First off, we cross multiply. So 374/(x-10) = -22/1 would be: 374 = -22(x-10). We then get 374 = -22x +220. You would subtract 220 from both sides then divide by -22 to get x. You could then substitute -7 in for x, to check your answer.

A.$3.50
B.$6.49
C.$9.34
D.$9.64
Answer:
it is b

twelve eggs cost $3.12. how much does one egg cost
Answer:
.26 cents
Step-by-step explanation:
3.12 divided by 12.
each individual egg is priced at $0.26
To find the cost of one egg, we can divide the total cost by the number of eggs. In this case, since twelve eggs cost $3.12, we can calculate the cost of one egg by dividing $3.12 by 12.
Dividing $3.12 by 12 gives us $0.26. Therefore, one egg costs $0.26.
This means that each individual egg is priced at $0.26. If you were to purchase just one egg from the given batch, it would cost $0.26.
Calculating the cost per unit helps us determine the price of individual items when they are sold in a larger quantity or package. In this case, dividing the total cost by the number of eggs allows us to find the cost of a single egg.

1.Jamal sells sandwiches. He spends $2.70 per sandwich on ingredients and then adds a 110% markup. What is the selling price of one sandwich?
2.Elizabeth goes to a restaurant where her bill comes to $18.50. She leaves the server a 22% tip. What is the total cost of going to the restaurant?
Answer:
2.70 + 110% = 5.67$ per sandwich
110% out of 2.70 is 2.97, so 2.70+2.97 = 5.67
18.50 + 22% = 22.57$ total cost
22% out of 18.50 is 4.07, so 18.50+4.07 = 22.57

Use the graph below to fill in the blank with the correct number:
f(0) = (1 point)
From the graph,
f(0) = 1
Notice that when x = 0, y = 1.
If we plot the point (0,1) It's the same point. So f(0) = 1 is basically substituting x = 0 and get y = 1

Calculate the slope of a line that goes through the points: (5, 7) & (2, 7). Leave your solution as a simplified (improper) fraction.
Answer:
0
Step-by-step explanation:

m=(7-7)/(2-5)
m=0/-3
m=0

Given the triangle below, what equation would you use to solve for x? Use your equation to determine the TWO unknown angle measurements.
Answer:
x=15
Step-by-step explanation:
so we are given one angle 90, although x is used in both so you can add them. We know that the sum of angle measures in a triangle is 180 so the equation is: 90+6x=180
subtract 90 from both sides: 6x=90
divide by 6: x=90/6
simplify: x=15
