1. would have to be team E because add up all the numbers 1058/8 (which is how many numbers that is there) 132.25.

2. (More of an explanation if you still don't understand)

52+52+53+54+55+55=321/6=53.5

52+53+54+55+57+57=328/6=54.66 repeated rounded to 54.7 so your answer is 1.2

What is the arc measure of abc in degrees

Virty [35]

<u>Given</u>:

The measure of arc AB is (4y + 6)°

The measure of arc BC is (20y - 11)°

The measure of arc AC is (7y - 7)°

We need to determine the measure of arc ABC.

<u>Value of y:</u>

The value of y is given by

$m \widehat{AB}+m \widehat{BC}+ m \widehat{AC}=360$

Substituting the values, we get;

$4y+6+20y-11+7y-7=360$

Adding the like terms, we have;

$31y-12=360$

Adding both sides of the equation by 12, we have;

$31y=372$

$y=12$

Thus, the value of y is 12.

<u>Measure of arc ABC:</u>

The measure of arc ABC can be determined by adding the measure of arc AB and arc BC.

Thus, we have;

$m \widehat{ABC}=m \widehat{AB}+ m \widehat{BC}$

$m \widehat{AB}+m \widehat {BC}=4y+6+20y-11$

$=24y-5$

Substituting y = 12, we get;

$m \widehat{AB}+m \widehat {BC}=24(12)-5$

$=288-5$

$m \widehat{AB}+m \widehat {BC}=283^{\circ}$

Thus, the measure of arc ABC is 283°

36 is what percentage of 128?<br> A. <br> B. 28 %<br> C. 28.125 %<br> D. 4,608%

skad [1K]

Answer:

C is the correct answer:

<h2>Solution for 36 is what percent of 128:</h2>

To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 128 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 100% equals 128, so we can write it down as 100%=128.

4. We know, that x% equals 36 of the output value, so we can write it down as x%=36.

5. Now we have two simple equations:

1) 100%=128

2) x%=36

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:

100%/x%=128/36

6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 36 is what percent of 128

100%/x%=128/36

(100/x)*x=(128/36)*x - we multiply both sides of the equation by x

100=3.55555555556*x - we divide both sides of the equation by (3.55555555556) to get x

100/3.55555555556=x

28.125=x

x=28.125

36 is 28.125% of 128

Step-by-step explanation:

Determine if the sequence is algebraic or geometric, and find the common difference or ratio. x 1 2 3 4 f(x) 81 72 63 54

sergeinik [125]

Answer:

The given sequence is Algebraic (Arithmetic) with common difference is -9.

Step-by-step explanation:

The given sequence is Arithmetic Sequence.

Arithmetic Sequence is a sequence in which every two neighbor digits have equal distances.

Geometric Sequence is the sequence in which every digit is the same multiplier of its previous digit.

The given sequence is: 81, 72, 63, 54,...

Here, First term(a) = 81, Second term(b) = 72

Common difference (d) = b - a = 72 - 81 = -9

Hence, Common difference is -9.
