Answer:
The angles of A and B are 45 degrees. This is true because the other angle is a right angle (90 degrees) and if you are making a triangle the degrees of the sides have to = 180 to be a complete triangle. The triangle is complete, so I took 180 – 90 = 90 ÷ 2 = 45.
The angle of C is 115 because it is a supplementary angle. A supplementary angle is an angle that has two angles with a sum of 180 degrees and 180 – 65 = 115The angles of A and B are 45 degrees. This is true because the other angle is a right angle (90 degrees) and if you are making a triangle the degrees of the sides have to = 180 to be a complete triangle. The triangle is complete, so I took 180 – 90 = 90 ÷ 2 = 45.

2.2 + 12x = -4
Answer:
−0.516667
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
12x+2.2=−4
Step 2: Subtract 2.2 from both sides.
12x+2.2−2.2=−4−2.2
12x=−6.2
Step 3: Divide both sides by 12.

Box contains 3 red and 5 white balls, while Box II contains 4 red and 2 white balls. A ball is chosen at random from the first box and placed in the second box without observing its color. Then a ball is drawn from the second box. Find the probability that it is white.
A ball is drawn from the second box. The probability that it is white. is 3/8
What is probability ?The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true.
An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.
The probability is computed by dividing the total number of possible outcomes by the number of possible ways the event could occur. Probability and odds are two distinct ideas. Odds are calculated by dividing the likelihood of an event by the likelihood that it won't.

$9,800,000 is what percent of $7,000,000
Answer:
686000000000
Step-by-step explanation:
1. We assume, that the number 7000000 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 7000000 is 100%, so we can write it down as 7000000=100%.
4. We know, that x is 9800000% of the output value, so we can write it down as x=9800000%.
5. Now we have two simple equations:
1) 7000000=100%
2) x=9800000%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
7000000/x=100%/9800000%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for what is 9800000% of 7000000
7000000/x=100/9800000
(7000000/x)*x=(100/9800000)*x - we multiply both sides of the equation by x
7000000=1.0204081632653E-5*x - we divide both sides of the equation by (1.0204081632653E-5) to get x
7000000/1.0204081632653E-5=x
686000000000=x
x=686000000000
now we have:
9800000% of 7000000=686000000000

Mr. Powell rents a storage space that is 7 feet high, 5 feet long, and 4 feet wide.
How many containers, each one cubic foot in volume, can Mr. Powell fit into the storage space?
Answer:
To find how many 1 by 1 containers can fit in his storage space we must find the volume of the storage space in cubic feet. The formula for the volume of a rectangular prism aka the room is length x width x height. With this formula, all we need to do is plug in all the values given to the variables.
volume = length x width x height = 5 x 4 x 7 = 20 x 7 = 140
Final Answer: 140 one foot by one foot containers can fit in Mr. Powell's storage space

Nancy has a rectangular garden with length, I, width, w, and a perimeter of 28 feet The length of the rectangle is 2 less than 3 times the width. Choose the system of equations that can be solved to find land w
Answer:Perimeter =2l +2w
28=2(3x-2) + 2x
Width =4feet
Length =10feet
Step-by-step explanation:
Perimeter of rectangular garden =2(l+b)
Let the width be represented as X
And the length which is 3x-2
Such that the equation to solve for length and width be
Perimeter =2l +2w
28=2(3x-2) + 2x--- system of equation
Solving
28=2(3x-2) +2x
28=6x-4+2x
28=8x-4
28+4=8x
32=8x
X=32/8
X=4
Width =4
Length =3x-2=3x4-2=10
A teacher has two large containers filled with blue, red, and green beads, and claims the proportions of red beads are the same in each container. Each student shakes the first container, selects 50 beads, counts the number of red beads, and returns the beads to the container. The student repeats this process for the second container. One student’s samples contained 13 red beads from the first container and 16 red beads from the second container.
Based on the 95% confidence interval, (–0.24, 0.11), is the teacher’s claim justified?
The teacher’s claim is not justified because the two sample proportions are different.
The teacher’s claim is not justified because the interval contains both positive and negative values.
The teacher’s claim is justified because the interval contains 0, meaning there is no difference in the proportions of beads in each container.
The teacher’s claim might not be justified because the interval contains both positive and negative values. It is plausible that the proportion of red beads in each container is different.
Answer:
D. The teacher’s claim might not be justified because the interval contains both positive and negative values. It is plausible that the proportion of red beads in each container is different.

3 is the rise and 7 is the run. You start at (0,0) and you go up 3 units, then 7 units right. The first coordinate should be (7,3). Repeat until you have a straight line.

What is the decimal multiplier to increase by 6.1%?
first add or subtract the percentage from 100 ,then convert to a decimal.
What is a simple definition of the multiplier?
It is the number of times a rise in national income exceeds the rise in injections of demand that caused it.
What is the multiplier process?
The multiplier effect comes about because injections of new demand for goods and services into the circular flow of income stimulate further rounds of spending – in other words “one person’s spending is another’s income”
This can lead to a bigger eventual final effect on output and employment.

What is the percent change from pre-cooked weight to final weight?
Answer:
new = 1/3 old = 1/2
new - old = 1/3 - 1/2 = 2/6 - 3/6 = -1/6
dividing by the old: -1/6 divided by 1/2 = -1/6 * 2/1 = -1/3
multiplying by 100% : -100/3 = -33 and 1/3 %
It is a 33 and 1/3 % DECREASE
