Find the measure of each of the following
Which of the following situations combine to make zero?
A- A friend opens a checking account with $30. His first purchase made with his debit card totals $28
B- The temperature falls 10 degrees below zero and then rises 20 degrees to be 10º F
C- A friend borrows $20 and promises to return double the amount.
D- A start up business has income equal to its expenses.
Answer:
D
Step-by-step explanation:
Why A is wrong:
If a friend has $30 in his checking account and he made a purchase of $28, the equation would be:
30-28 = $2, which does not equal zero.
Why B is wrong:
The temperature was zero and went down to negative ten. It went up to 10, not zero. So this is also wrong.
Why C is wrong:
A friend borrowed $20 dollars and promised to return double the amount, $40. The equation for this is:
20 - 40 = -20, which also does not equal zero
Why D is correct:
Income is how much you earn
Expenses is how much you pay.
If both of them are equal, then your income is zero, which is the correct answer.
Hope this helps :)

BRAINLIEST IF correct
Answer: 4.6 cattle
Step-by-step explanation:
Since you are finding the average, you have to...
Step 1: Add all of the numbers:
4 + 1 + 9 = 14
Step 2: Divide 14 by 3 (the amount of numbers added)
14 ÷ 3 = 4.666666666667 (to be exact)

which angles are complementary to each other ? select all that apply
Answer: ∠1 and ∠5
Step-by-step explanation:
You can see that all of the other angles are exactly 90 degrees. The remaining two are angles 1 and 5 which means that they have to be 90 degrees. Since they are together, they also look perfectly like a 90 degree angle.
Hope this helps :)

Step-by-step explanation: CALCULATE
Answer:
the answer would be a is correct
im very confused on this please help me:)
The constant rate of change is how much y increases every time x increases by 1. We might be confused because in this table, we see a number of points, but we don't see any consecutive x-values, so it might seem difficult. But no worries!
All you have to do is calculate using the formula, Δy divided by Δx. What does Δy divided by Δx mean?
All we have to do is look at two points. Let's take, for example, (-2, -10) and (2, -8).
-2 and 2 are the x-values of the points and -10 and -8 are the y-values of the points as coordinates are in the format of (x, y).
All we have to do is minus the y-coordinates and then proceed the minus the x-coordinates. The order does not matter, as in you can do either of these ways:
[(-10) - (-8)] ÷ [(-2) - (2)] = -2 / -4 = 1/2
or
[(-8) - (-10)] ÷ [(2) - (-2)] = 2 / 4 = 1/2
So the constant rate of change or the answer is 1/2.
What is the volume of each figure? Round to the nearest tenth if necessary.

Step-by-step explanation:
The Smith family have decided to build a uniform walkway that is 3 ft wide using Travertine pavers around their rectangular swimming pool which measures 16 ft by 24 ft.
What is the area of the walkway? - 384 ft sq.
The paver selected by the family measures 6 in by 12 in. How many pavers are needed to cover the walkway?
Answer:
not sure
Step-by-step explanation:
6*12=72, 72in to feet is 6ft
384/6=64ft
Answer:
384 divided by 72 (6 times 12) = 5.33 i think
HELPPPPPP QUICKKKKK!!!!!!!!!!
Answer:
35x+55 = 160
Step-by-step explanation:
Cost equal flat rate plus rate per hour times hours where x is the number of hours worked
cost = 55 + 35x
160 = 55 + 35x
Rewriting
35x+55 = 160

Tim has X beads
Amy has 2 more beads than Tim
Sarah has 5 times as many beads as Amy
How many beads does Sarah have?
Answer:
5x + 10
Step-by-step explanation:
Amy has 2 more beads than Tim, x, so she has x + 2 beads.
Sarah has 5 times more beads than Amy, so 5(x + 2). Simplifying this, we get 5x + 10
Sarah has 5x + 10 beads
I’ll fail if I don’t get this right pls help
Step-by-step explanation:
In order to find the number of solutions, we have to expand both sides out first.
[tex]3(x - 2) + 7x = \frac{1}{2} (6x - 2)[/tex]
First, expand 3(x-2), which will obtain 3x-6.
Next, expand (1/2)(6x-2), which gives 3x - 1.
The result at this point should be as shown below:
[tex]3x - 6 + 7x = 3x - 1[/tex]
Now, we would shift all x terms to the left and all number terms to the right.
[tex]3x + 7x - 3x = - 1 + 6[/tex]
After simplifying, the final equation would be:
[tex]7x = 5[/tex]
This is a linear equation and it has one solution.
[tex]x = \frac{5}{7} [/tex]
Answer:
x = 5/7

2. At a fair, each person can spin two wheels of chance. The first wheel has the numbers 1, 2, and 3. The second wheel has the letters A and B. (d) List all the possible outcomes of the compound event. (e) If you spin both wheels, what is the probability that you get either a 1 or an A? Explain.
And pls don’t answer if you don’t know it.
Answer:
Possible outcomes: 1a 1b 2a 2b 3a 3b
Outcomes for spinning a one = 2
1a, and 1b 2/6
Outcomes for spinning an "a" = 3
1a, 2a, and 3a.
1a is already in the first set so we can exclude it. 2/6
2/6+2/6=4/6
There is a 4/6 or 2/3 chance of getting either an a or an 1
Answer:
(d) 1A, 1B, 2A, 2B, 3A, 3B
(e) 2/3 or 66.66% chance
Explanation is below
Step-by-step explanation:
(d) The Total outcomes are 3*2 = 6, because there are 3 numbers and 2 letters.
The outcomes are:
1A
1B
2A
2B
3A
3B
(e) Of the 6 outcomes, 3 of them have A and 2 of them have 1. But one of them has an A and 1, so it is 4 outcomes: 1A, 1B, 2A, and 3A.
So it is 4/6 = 2/3, or 66.66...% chance

which angles are complementary to each other select all that apply
Answer: 4 and 1
Step-by-step explanation:
Both ∠4 and ∠1 are equal angles. Both the angles are beside a right angle and you can measure it. The other answers are over 90 degrees, or below 90. This is because they either combine a 90 degree angle with another angle, or that they are too small and obvious that they are not complementary.
Answer:
<2 and <4
complimentary <s add up to 90 °
