Explanation:
Check out the diagram below.
Segment BD cuts angle EBC in half
So the two smaller pieces DBC and DBE are congruent. Let's call them x.
Let's make y = angle EBA.
Note how the diagram shows the angles x, x, and y forming a straight angle. So we can say
x+x+y = 180
2x+y = 180
y = -2x+180
We'll use this later.
For now, focus on triangle DEB. Angle E is 90 degrees and angle B is x.
D+E+B = 180
28+90+x = 180
x+118 = 180
x = 180-118
x = 62
Which means
y = -2x+180
y = -2*62+180
y = -124+180
y = 56
Now focus on triangle BEA. We have B = 56, E = 90 and A = z
B+E+A = 180
56+90+z = 180
146+z = 180
z = 180-146
z = 34
which is the measure of angle A.

y2-y1 is 7- (-5) = 12
x2-x1 is 6- (-2) = 8
the formula is y2 -y1 over x2-x1 so
12/8

A kitchen sink faucet streams 0.5 gallon of water in 10 seconds. A bathroom sink faucet streams 0.75 gallon of water in 18 seconds. Which faucet will fill a
3-gallon container faster?
Answers
Answer:
the kitchen sink faucet will fill the container faster than the bathroom faucet.
Step-by-step explanation:
I found the unit rate for both faucets in order to be able to compare them.
Kitchen faucet:
.5 gallons in 10 seconds = 1 gallon in 20 seconds (0.5 x 2= 1 gal, 10 sec x 2=20 seconds)
.75 gallons in 18 seconds = 1 gallon in 24 seconds (0.75 = 3/4 3/4 x 4/3=1 gallon, 18 x 4/3 = 24 seconds)

Answers
Answer:
For me it looks like downward and upward parabola.
The graph is periodical meaning that it repeats itself after some point. This is because the motion of the wheel makes the car move up and then come back down again. Each local min point is likely where the riders get on the ride, since its closest to the ground. Each local max point is the highest point on the graph indicating when the car is at the top of the wheel.
Let's say that the vertical distance from the lowest point to the highest point is 50 feet, just as an example. This would mean the amplitude is half that at 50/2 = 25 feet. The amplitude represents the vertical distance from the center line to either the highest or lowest point.
The period describes how long each cycle takes. For instance, if it takes 60 seconds for a specific car to go from the bottom position, loop around, and then come back to the bottom position, then the period is 60 seconds. The frequency is simply 1 over the period. Though the frequency may not be used as much.
So overall this curve is likely a sine or cosine curve (depending on the phase shift of course). Also there's a vertical shift as well. Because we don't have any numbers to work with, the actual sine or cosine function cannot be determined.

Donny joined a club that costs $40 per month. Is the cost over time a proportional or non-proportional relationship?
Answers
Answer:
The cost over time is a proportional relationship
Step-by-step explanation:
Proportional relationships are relationships between two variables where their ratios are equivalent. Another way to think about them is that, in a proportional relationship, one variable is always a constant value times the other. That constant is know as the "constant of proportionality"
Suppose there are two blocks of solid iron. One block is a cube, three inches on a side. The other block is a cube three miles on a side. Obviously, the large cube is many, many times greater volume than the small cube, and many, many times heavier. Is the large cube more dense than the small cube, or less dense?
Answers
Answer:
The density is the same because both cubes are composed of the same element Iron(Fe).
Answer:
I believe the large cube would be denser.

Stan borrows $5,500 at a rate of 12% interest per year. What is the amount due at the end of 5 years if the interest is compounded continuously? In your final answer, include your calculations.
Answers
Answer:
1.) Without compound interest, you would earn only $8800.00. This means that thanks to the power of compound interest you will earn an additional $1191.83 in interest at the end of the 5 year term.
2.) Using the compounded interest formula, you will earn $22883.01 after the 7 year term.
3.) Because of the negative interest, the compounded amount is only $695,929.30.
4.) Putting money in a saving account is saving money with a lower earning compared to investments. Investments have the higher potential of earning more than just having a basic savings account.
Step-by-step explanation:
If you don't have compound interest, you would earn only $8800.00. This means that thanks to the power of compound interest you will earn an additional $1191.83 in interest at the end of the 5 year plan.

An ostrich is being chased by a cheetah,
The ostrich is running at 44 feet per
second and the cheetah at 110 feet per
second. If the two started at the same
place and the ostrich got a 60-second
head start, how many seconds will it be
before the cheetah catches it?
Answers
Answer:
40 seconds
Step-by-step explanation:
(ostrich speed * seconds) + head start = (cheetah speed * seconds)
44x + (44 * 60) = 110x
44x + 2640 = 110x
2640 = 66x
x = 40
No. of seconds before cheetah catches ostrich = 40 seconds
What is speed?Speed tells us how slow or fast an object moves. It describes the distance travelled divided by the time taken to cover the distance.
Speed is directly Proportional to Distance and Inversely proportional to Time.
Speed = Distance/Time
Given,
Speed of ostrich = 44 feet per second
Speed of cheetah = 110 feet per second
Starting point is same
Ostrich got 60 second head start
Distance travelled by ostrich in 60 second = 44 × 60 = 2640 feet
let S be the number of seconds that it will take the cheetah to catch the ostrich
Distance covered by cheetah = 110S
Distance that the ostrich will cover before being caught is 2640 + 44S
According to the question
110S = 2640 + 44S
110S - 44S =2650
66S = 2640
S = 2640/66
S = 40 seconds.
Hence, It will be 40 seconds before cheetah catches the ostrich.

Answers
Answer:
30 stamps each
Step-by-step explanation:
This is the correct question:
Jessica has 120 stamps in a collection she bought 60 more Jessica wants to place the stamps equally and 6 pages of a book how many stamps will be on each page of the book
Total stamps = 120 + 60
= 180
Jessica wants to place the stamps equally on 6 pages of a book
how many stamps will be on each page of the book?
Each page of the book = Total stamps / number of pages in the book
= 180 / 6
= 30
Each page of the book will have 30 stamps each
five less than three times a number is 1. What is the number?
Answers
Answer: 3 times a number can be written as 3x.
Five less than 3x means you must subtract 5 from 3x.
the word "is" means equals,
so 3x-5=10
Step-by-step explanation:
since it is given that 3 times a number less than five is 1
since it is given that 3 times a number less than five is 1 getting equation:- 3x-5=1
since it is given that 3 times a number less than five is 1 getting equation:- 3x-5=1 x=6/3
since it is given that 3 times a number less than five is 1 getting equation:- 3x-5=1 x=6/3 x=2
