Answer: Where is the problem???
Step-by-step explanation:
The price of Stock A at 9 A.M. was $13.64. Since then, the price has been increasing at the rate of $0.06 each hour. At noon the price of Stock B was $14.39. It begins to decrease at the rate of $0.11 each hour. If the two rates continue, in how many hours will the prices of the two stocks be the same?
Answer: In about 3 hours and 21 minutes the prices of the two stocks will be the same at $14.02
Step-by-step explanation: We can begin by calculating the value of stock A at noon by adding $.06 per hour or 3 hours, $0.18 to its 9am price. $13.64 + 0.18 = 13.82
Then set up the equation to find the point where the prices are equal:
x is the amount of time in hours.
.06x + 13.82 = -.11x + 14.39
Add .11x to both sides and subtract 13.82 from both sides
.06x + .11x = 14.39 - 13.82
.17x = 0.57
x = 3.353 hours
To get minutes instead of a decimal, multiply .353 × 60 ≈ 21 minutes
The time is 3:21
The increase in price is for stock A is about $0.20
13.82 + .0.06(3.353) = $14.02
Stock B decreased by $0.37
14.39 - 0.11(3.353) = $14.02

C: Naomi is faster because she runs a full mile in 8 minutes while Amal runs a mile in 12 minutes.
Step-by-step explanation:
Since he can run 1/8 miles in 1.5 minutes, times 1.5 by 8 to get a mile. Then times that by 3 to get 3 miles. Now calculate how long it takes Naomi to run a mile, 2 times 4 which is 8 minutes. We know Amal runs a mile in 12 minutes, so Naomi is faster.

NEED HELP!! WILL MARK BRAINLEST!!!! 8676 divded by 0.94 x 574.1 =??
Step-by-step explanation:
5,298,820.8510638
hope this helps
Answer:
16.0769678
Step-by-step explanation:
Since it is 8676 diveded by 0.94*574.1, you would first multiply 0.94 by 574.1. Once you do that you should get the answer 539.654. After that, you would divide 8676 by 536.654. You should get the answer, 16.0769678.

Answer:
angle x=40
Step-by-step explanation:
Angle CD on the bottom is a 180 angle. If you subtract it by 110 it's 70. The two bottom angles are equal so it also equals 70, add them and you get 140. Subtract 180 by 140 and it means x=40!

What is the value of x, if the perimeter of the rectangle is 37?
This is the problem :
Answer:
X= 3.7
Step-by-step explanation:
Perimeter of rectangle= 2(L+B)
37= 2(4X+X)
37= 2(5X)
37= 10X
37/10=X
3.7= X

HELP I CANT DO MATH PLEASE
Answer:
A' : (-5, -8)
B' : (-5, -1)
C' : (2, -1)
Step-by-step explanation:
A is (-5, 8), B is (-5, 1), C is (2, 1), and we want to find the points after we reflect the triangle over x.
The first thing to remember is that when points are written like (x, y), the first number, x, is how many units you go right or left and the second number, y, is how many units you go up or down. The second thing to keep in mind is that the x-axis is the horizontal one that runs from left to right.
Now, just think about the information we have: if we want to flip a point like (-5, 8) over the x-axis, all we have to do is make the 8 negative. This is because the 8 is how far up the point is, so to make it flip down over the x-axis, we just change the sign. The -5 does NOT change because it's the x-value, which is how far right/left the point is. Does that make sense?
If we do this for the other two, (-5, 1) becomes (-5, -1) and (2, 1) becomes (2, -1).
(The apostrophe-like symbol the problem uses--like A', B', C'--just denotes that those are the resulting points after the reflection.)

At a college, the cost of tuition increased by 10%. Let y be the former cost of tuition. Use the expression y+0.10y for the new cost of tuition. Write an equivalent expression by combining like terms. What does your equivalent expression tell you about how to find the new cost of tuition?
Choose the correct answer below.
A. 0.10; add 0.10% of the former cost to the new cost.
B. 1.10y; multiply the former cost by 1.10.
C. 0.90y; multiply the former cost by 0.90.
D. 0.90; add 0.90% of the new cost to the former cost.

Point Q is plotted on the coordinate grid. Point P is at (10, −20). Point R is vertically above point Q. It is at the same distance from point Q as point P is from point Q. Which of these shows the coordinates of point R and its distance from point Q?
Answers:
A. Point R is at (−20, −30), a distance of 10 units from point Q
B. Point R is at (−20, 10), a distance of 30 units from point Q
C. Point R is at (−20, −10), a distance of 30 units from point Q
D. Point R is at (−20, 30), a distance of 10 units from point Q
The answer is B.
Since Point P is 30 units away from Point Q, Point R is vertically above Point Q the same distance Point P is from Point Q, which is 30 units, that means your answer is B. Point R is at (-20, 10), a distance of 30 units from Point Q

A machine can enlarge a 6– inch by 4– inch regular photograph to any of the dimensions shown in the table below. Which equation represents the relationship between I, the length of the enlargement, and w, the width of the enlargement?
Answer:
c. w = 2/3l
Step-by-step explanation:
for a., none of the values fit so it can't be a.
for b., the second row fits but none of the others do so it can't be b.
for c., every single row fulfills the equation so the answer is c.
for d., the first row fits but none of the others do so it can't be d.
since there are only four choices it's fine to plug and test.
