A train was traveling at a constant speed. The table below shows the distance, in miles, the train traveled for the first 4 hours.
Time (hours) Distance (miles)
1
95
2.
190
3
285
4
380
Write an equation to represent the relationship between the time, and d, the total distance traveled by the train.
Answer:
d=95t
d= 95 times the time
e.g d=95t
95=95*1
The cost of making a shirt is half of what the shirt normally sells for. Today, the shirt is in a 15 percent discount from its normal price. What is the current price of the shirt?
Answer:
.85 times the cost to make the shirt
Step-by-step explanation:
Let x represent cost to make the shirt.
Today, the shirt is in a 15 percent discount from its normal price.
Discount = 15/100 * x = 0.15x
Current cost = Original cost - discount
Current cost = x - 0.15x = 0.85x
The answer is;
.85 times the cost to make the shirt

please help me im so confused
Answer:
x = 27
Step-by-step explanation:
A circle adds up to 360 degrees. So we make this equation:
2x+21 + 5x+6 + 54 + 90 = 360
Combine like terms:
7x + 171 = 360
Subtract both sides by 171
7x = 189
Divide both sides by 7
x = 27
Answer:
Step-by-step explanation:
this has a bunch of "implied" things that you're supposed to know. one is that all the way around a circle is 360° two is that if you know the angle on the interior.. that is also the arc length.. so knowing those things we can say
360 = 54 + 2x + 21 + 5x + 6 + 90
put like terms together
360 = 171 + 7x
189 = 7x
27 = x
Interest = $72.30
Principle = ?
Rate = 5%
Time = 3 years
Answer:
Step-by-step explanation:
Answer:
P = $ 482.00
Equation:
P = I / rt
Calculation:
First, converting R percent to r a decimal
r = R/100 = 5%/100 = 0.05 per year,
then, solving our equation
P = 72.3 / ( 0.05 × 3 ) = 482
P = $ 482.00
The principal required to
accumulate interest of $ 72.30
on a rate of 5% per year for 3 years is $ 482.00.
hope it helps :)

507 people use the public swimming pool , the daily price for children is 1.75 and the price for adults is 2.25 and the admission total was 971.75 how many children were at the public pool
Answer: 338 children
Step-by-step explanation:
Assume the children are represented by x and the adults are y.
Relevant equations will be:
x + y = 507 people
1.75x + 2.25y = 971.75
y = 507 - x
1.75x + 2.25 * ( 507 - x) = 971.75
1.75x + 1,140.75 - 2.25x = 971.75
1.75x - 2.25x = 971.75 - 1,140.75
-0.5x = -169
x = -169/-0.5
x = 338 children
Adults = 507 - 338
= 169 adults

15. Marley gets on an elevator on the 30th floor of a building. She goes up 6 floors to pick up a package then goes down 14 floors for a meeting. Write and simplify an expression to show what floor Marley is now on pls help
Step-by-step explanation:
The initial level is 30.
let the upward travel be +X and downward travel be -Y.
so the expression for her current level be ,
30+X-Y = 30+6-14= 22.
22 is her current level.

THIS IS WORTH 24 FREAKING POINTS SO GIVE ME NO WRONG ANSWER NOW, read the question carefully and answer it correctly and carefully
Answer:
I am not the best at math but I know that u can't change the bottom half of the fraction so it would just be four and then multiply the five and the three which would be fifteen. The answer would be 15/4ths. So you want to color in 15 boxes. Hopefully I could be of some kind of help to you!
Answer:
color in 15 boxes
15/32
Step-by-step explanation:
first off, the points are split so I'm only getting 12, just so that you know.
so 1/8x1/4 is 1/32, so each box is 1/32.
5/8x3/4=15/32 (multiply the top of the first with the top of the second and the bottom of the first with the bottom of the second)
so color in 15 boxes and the answer to the multiplication is 15/32

The angles of a triangle are in the ratio 1:2:3.What are the three angles of a triangle?
Answer:
30°, 60°, 90°
Step-by-step explanation:
sum the parts of the ratio, 1 + 2 + 3 = 6 parts
divide the sum of the angles in a triangle. 180° by 6 to find the value of one part of the ratio.
180° ÷ 6 = 30° ← value of 1 part of the ratio , then
2 parts = 2 × 30° = 60°
3 parts = 3 × 30° = 90°
The 3 angles are 30°, 60° and 90°

Consider triangle WXY. Triangle W X Y is shown. The length of side W X is 5, the length of side X Y is 10, and the length of side W Y is 14. Which statement about the angles is true? Angle W is greater than angle Y. Angle Y is the largest angle. Angle X is smaller than angle W. Angle W is the smallest angle.
Answer:
Angle W is greater than angle Y
Step-by-step explanation:
The angles in the triangles when solved are given as follows;
∠Y = 14.57
∠X = 135.23
∠W = 30.2
Angle W is greater than angle Y
This is Correct
Angle Y is the largest angle
This is Incorrect
Angle X is smaller than angle W
This is Incorrect
Angle W is the smallest angle.
This is Incorrect
Answer:
A Angle W is greater than angle Y.
Step-by-step explanation:
Because line WX is smaller than XY
