Answer:
The measure of the angles are 112 degrees and 68 degrees.
Step-by-step explanation:
Two angles are supplementary if they add up to 180 degrees.
The first angle is 8x degrees.
The second angle is (4x+12) degrees.
Therefore:
8x+4x+12=180 degrees
12x+12=180
12x=180-12
12x=168
Divide both sides by 12
x=14 degrees
Substituting x in the given angles:
8x =8*14=112 degrees
4x+12=4(14)+12=68 degrees
Therefore, the measure of the angles are 112 degrees and 68 degrees.

The data in the table below for my function. What values in the table would change the relation to NOT be a function?
A) (1,9)
B) (-3,7)
C) (9,4)
D) (6,5)
If we add pair D (6, 5) to the table, then it stops representing a function.
What values in the table would change the relation to NOT be a function?
A relation is not a function if we can see that we have a input that is mapped into two (or more) different outputs.
Notice that in the table we already have an entry with the input x = 6, so we can't add another entry like:
(6, 5)
Because then, the table wouldn't be a function.
Then the correct option is D.

Which of the following shows the correct order of the numbers?
..0.8
The correct answer is: A. -1.3, -1.2, 0.8, 0.9. Hence the correct option is a.
Start by comparing the negative numbers:
Since -1.3 is a smaller number than -1.2, we know -1.3 comes first.
Compare the negative numbers with the positive numbers:
All negative numbers are less than any positive number. Therefore, both -1.3 and -1.2 come before 0.8 and 0.9.
Compare the positive numbers:
Finally, compare 0.8 and 0.9. Since 0.9 is larger, it comes last.
Therefore, the order from least to greatest is: -1.3, -1.2, 0.8, 0.9. This corresponds to option A.
Complete and correct question:
Which of the following shows the numbers in order of least to greatest? 0.9, -1.2, -1.3, 0.8
A. -1.3, -1.2, 0.8, 0.9
B. -1.2, -1.3, 0.8, 0.9
C. 0.8, 0.9, -1.2, -1.3
D. 0.9, 0.8, -1.2, -1.3
Simplify. Rewrite the expression in the form 5n.
5(2) x 5(5) =
To simplify the expression 5(2) x 5(5), we first calculate the result as 250. To rewrite this in the form 5n, we find a number n such that 5 times n equals 250, which is 50. Thus, the original expression can be written as 5(50).
Explanation:The question asks to simplify the given mathematical expression. The expression is 5(2) x 5(5). When we multiply the numbers in each parenthesis with 5, it simplifies to 10 x 25, which equals 250 when multiplied together. This answer, however, is not in the form of 5n.
To rewrite the answer in form of 5n, we need to find a number that, multiplied by 5, equals to our answer, 250. This number is 50, because 5 times 50 equals 250.
Therefore, the expression 5(2) x 5(5) equals 250 and can be rewritten in the form of 5n as 5(50).

Give your answer as a fraction in its simplest form.
Answer:
1/12
1/2 x 1/6 = 1/12
half of the numbers are even and 1/6 o the numbers is 3.
Step-by-step explanation:
The probability of rolling an even number and then a 3 is,
⇒ 1 / 12
What is mean by Probability?The term probability refers to the likelihood of an event occurring. Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.
Now, the probability of rolling an even number on the first roll.
Then, There are three even numbers 2, 4, and 6 out of the 6 possible outcomes,
so the probability of rolling an even number on the first roll is,
= 3/6,
= 1/2
And, For the probability of rolling a 3 on the second roll.
There is only one outcome that will result in a 3 out of the six possible outcomes,
so the probability of rolling a 3 on the second roll is 1/6.
Now we can multiply the two probabilities together to find the probability of rolling an even number on the first roll and then a 3 on the second roll:
1/2 x 1/6 = 1/12
Hence, the probability of rolling an even number and then a 3 is,
⇒ 1 / 12

HI I NEED HELP PLS I SO DUMB TO DO THIS PLS HELP!!
Answer:

Step-by-step explanation:
Angles are named with the vertex listed in the middle of the three letters. For example, ∠AFB is formed by rays FA and FB. Point F is the vertex of the angle, where the rays meet.
Adjacent angles share a ray. Generally the shared ray will be the only ray between the other two rays identifying the angles. For example, ∠AFB and ∠BFC (or ∠CFB) are considered to be adjacent because shared ray FB is between rays FA and FC.
Given the names of two angles, you can look to see if any of the rays are shared.
Looking at the next answer choice, ∠AFB and ∠CFD we see that the rays involved in the first angle are FA and FB; in the second angle they are FC and FD. There are no common rays here, so these angles are not adjacent.
∠BFC and ∠CFD share ray FC. They are adjacent.
∠BFC and ∠DFE have no shared rays.
∠CFD and ∠DFE share ray FD. They are adjacent.

The Massachusetts Department of Employment and Training predicted that there will be 21% more jobs for computer programmers in Massachusetts in 2005 than there were in 1994.
There were 15,970 programming jobs in 1994.
Based on the prediction, about how many total jobs were there available in 2005?
Answer:
19,324
Step-by-step explanation:
The original amount is 100% of the original amount since 100% means a whole amount.
A 21% increase means that the new amount will be 100% + 21% = 121% of the original amount.
Now we calculate 121% of 15,970.
To find a percent of a number, multiply the percent by the number. First, divide the percent by 100 to change it into a decimal.
121% of 15,970 =
= 121% * 15,970
= 1.21 * 15,970

suppose 7,330 dollars is invested at 14.8% per annum for 10 years compounded monthly, how many dollars will be earned in interest during those 10 years, to the nearest cent
Answer:
$24,580.12
Step-by-step explanation:
Lets use the compound interest formula to solve:
[tex]A=P(1+\frac{r}{n} )^{nt}[/tex]
P = initial balance
r = interest rate (decimal)
n = number of times compounded annually
t = time
First, change 14.8% into a decimal:
14.8% -> [tex]\frac{14.8}{100}[/tex] -> 0.148
Since the interest is compounded monthly, we will use 12 for n. Lets plug in the values now:
[tex]A=7,330(1+\frac{0.148}{12})^{12(10)}[/tex]
[tex]A=31,910.12[/tex]
Now subtract that number from our original amount invested:
[tex]31,910.12-7,330=24,580.12[/tex]
The dollars earned in interest is $24,580.12

Find the scale factor of the figures below from left to right given the volume of each .
Explanation:
The volumes are in the ratio 3625:783 which reduces fully to 125:27 after dividing both parts by the GCF 29.
Both 125 and 27 are perfect cubes because 125 = 5^3 and 27 = 3^3
Therefore, the volume ratio 125:27 turns to the linear scale factor ratio 5:3
If you were to cube both sides of the linear ratio 5:3, you would get the volume ratio 125:27. Cube rooting both sides will have you go in reverse.
