Answer:Answer/Step-by-step explanation:

Given that m<3 = 54°

a. <1, <2, and <3 are angles on a straight line. They add up to 180°.

m<3 is given as 54°, m<2 = 90°, therefore,

m<1 = 180 - (54 + 90) = 180 - 144

m<1 = 36°

b. <2 is indicated as a right angle. Therefore, m<2 = 90°

c. <1 and <4 are vertical opposite angles. Vertical angles are congruent, since m<1 = 36°, therefore, m<4 = 36°

d. <5 and <2 are vertical opposite angles. m<2 = m<5, therefore, m<5 = 90°

e. <6 and <3 are vertical opposite angles. m<3 = m<6, therefore, m<6 = 54°

f. m<7 + m<6 = 180° (same side interior angles are supplementary)

m<7 = 180 - m<6

m<7 = 180 - 54

m<7 = 126°

g. m<7 + m<8 = 180° (linear pair)

126° + m<8 = 180

m<8 = 180 - 126

m<8 = 54°

h. m<9 = 180 - m<8 (linear pair)

m<9 = 180 - 54

m<9 = 126°

i. m<10 = m<8 (vertical angles)

m<10 = 54°

j. m<11 = m<4 (alternate interior angles are congruent)

m<11 = 36°

k. m<12 = 180 - m<11 (linear pair)

m<12 = 180 - 36

m<12 = 144°

l. m<13 = m<11 (vertical angles)

m<13 = 36°

m. m<14 = m<12 (vertical angles)

m<14 = 144°

Step-by-step explanation:

Answer:

A. M<1 = 36°

B. M<2= 90°

C. M<4= 36°

D. M<5= 54°

E. M<6= 54°

F. M<7= 126°

G. M<8= 54°

H. M<9= 126°

I. M<10 = 54°

J. M<11 = 36°

K. M<12 = 144°

L. M<13= 36°

M. M<14 = 144°

Equation: [tex] y = 14x [/tex].

It would take Martina 37 hours to earn $518

Step-by-step explanation:

✍️An equation that shows a proportional relationship between the time she spends babysitting (x) and amount of money she earns for babysitting (y) can be represented as [tex] y = kx [/tex], where k = constant of proportionality.

Let's find k using any of the pairs given in the table of values. Let's use (1, 14).

Substitute x = 1, and y = 14 into [tex] y = kx [/tex], and find k.

[tex] 14 = k(1) [/tex]

[tex] 14 = k [/tex]

Substitute k = 14 into [tex] y = kx [/tex].

✅The equation would be:

[tex] y = 14x [/tex].

✍️Using the equation, we can find how many hours Martina needs to work in order to earn $518 she wants to use to buy a new phone.

Simply, substitute y = 518 in [tex] y = 14x [/tex].

[tex] 518 = 14x [/tex]

Divide both sides by 14

[tex] \frac{518}{14} = x [/tex]

[tex] 37 = x [/tex]

✅Thus, it will take Martina 37 hours to earn $518

** Question #3 has a typo (a typographical error, a misprint, an error, a mistake, a blunder, an oops, an owee) on the question sheet.  The first number of the sequence should be 10,000 instead of 1000 .

1. If a sequence has a common ratio, it is called: C. Geometric Sequence

2. The sequence that does not have a common ratio of -2 is: A. -32, 16, -8, 4

3. The common ratio of 10,000, 1,000, 100, 10, 1 is: [tex]\mathbf{A. \frac{1}{10}}[/tex]

4. The sequences that are arithmetic sequence are:

D. I and IV.

5. The sequence that does not belong to the group is: A. 5, -10, 20, -40.

6. The next term of the geometric sequence is: C. [tex]\frac{1}{729}[/tex]

Recall:

1. Therefore, if a sequence has a common ratio, it is called: C. Geometric Sequence

2. Common ratio = next term / previous term

The sequence, -32, 16, -8, 4 has the following common ratio which is not -2:

[tex]\frac{4}{-8} = \frac{-8}{16} = \frac{16}{-32} = -\frac{1}{2}[/tex]

The common ratio is: [tex]-\frac{1}{2}[/tex]

Therefore, the sequence that does not have a common ratio of -2 is: A. -32, 16, -8, 4

3. Find the common ratio of: 10,000, 1,000, 100, 10, 1

Common ratio = next term / previous term

Thus:

Common ratio = [tex]\frac{1}{10} = \frac{10}{100} = \frac{100}{1,000} = \frac{1,000}{10,000} = \frac{1}{10}[/tex]

Therefore, the common ratio of 10,000, 1,000, 100, 10, 1 is: [tex]\mathbf{A. \frac{1}{10}}[/tex]

4. An arithmetic sequence is an ordered list whereby the next term is gotten by adding a constant to the previous term.

Simply put, the ordered list of numbers has a difference between each terms.

To find the common difference, subtract the previous term from the next term.

Thus:

-5, 0, 5, 10, 15 would have the following common difference:

0 - (-5) = 5

5 - 0 = 5

10 - 5 = 5

15 - 10 = 5

Also:

4, 1, -2, -5, -8 would have the following common difference:

1 - 4 = -3

-2 - 1 = -3

-5 -(-2) = -3

-8 -(-5) = -3

Therefore, the sequences that are arithmetic sequence are:

D. I and IV.

5. The sequence, 5, -10, 20, -40, is a geometric sequence, that is it has a common ratio as shown below:

Common ratio = [tex]\frac{-40}{20} = \frac{20}{-10} = \frac{-10}{5} = -2[/tex]

The rest of the sequence in the answer choices have a common difference and are arithmetic sequences except 5, -10, 20, -40.

Therefore, the sequence that does not belong to the group is: A. 5, -10, 20, -40.

6. To find the next term in the geometric sequence, [tex]\frac{1}{9}, \frac{1}{27}, \frac{1}{81}, \frac{1}{243}[/tex], find the common ratio.

Then multiply it by the last term to get the next term in the sequence.

Common ratio = Next term / previous term

[tex]= \frac{1}{27} \div \frac{1}{9} \\\\= \frac{1}{27} \times \frac{9}{1} \\\\= \frac{1 \times 9}{27 \times 1}\\\\= \frac{9}{27} \\\\= \frac{1}{3}[/tex]

Multiply [tex]\frac{1}{3}[/tex] by [tex]\frac{1}{243}[/tex] to get the next term:

[tex]\frac{1}{243} \times \frac{1}{3} = \frac{1 \times 1}{243 \times 3} \\\\= \frac{1}{729}[/tex]

Therefore, the next term of the geometric sequence is: C. [tex]\frac{1}{729}[/tex]

In summary,

1. If a sequence has a common ratio, it is called: C. Geometric Sequence

2. The sequence that does not have a common ratio of -2 is: A. -32, 16, -8, 4

3. The common ratio of 10,000, 1,000, 100, 10, 1 is: [tex]\mathbf{A. \frac{1}{10}}[/tex]

4. The sequences that are arithmetic sequence are:

D. I and IV.

5. The sequence that does not belong to the group is: A. 5, -10, 20, -40.

6. The next term of the geometric sequence is: C. [tex]\frac{1}{729}[/tex]

Answer:

130

Step-by-step explanation:

First you want to start in the one's place in 10000010, multiply the ones place with 2^0

then move to the left to the tens place with 2^1

hundreds place with 2^2 an so on

Decimal equivalent of "0" = 0 × 2^0 = 0

Decimal equivalent of "1" = 1 × 2^1 = 2

Decimal equivalent of "0" = 0 × 2^2 = 0

Decimal equivalent of "0" = 0 × 2^3 = 0

Decimal equivalent of "0" = 0 × 2^4 = 0

Decimal equivalent of "0" = 0 × 2^5 = 0

Decimal equivalent of "0" = 0 × 2^6 = 0

Decimal equivalent of "1" = 1 × 2^7 = 128

Next you want to add all the products you just got to get the decimal equivalent of 10000010

0 + 2 + 0 + 0 + 0 + 0 + 0 + 128 = 130

Therefore the binary number 10000010 in decimal is 130

Step-by-step explanation:

Two hot air balloons.

Balloon one: starts at 30 miles from town and after 2 hours, it is 48 miles

Distance of Tasha's balloon is represented by function y = 8x + 20

x is independent variable so it would represent the time.

y is dependent so it represents the miles travelled.

Balloon one = (0, 30) <-- begins here and (2, 48)

Balloon two = (0, 20).

So balloon one began at 30 miles while tasha's balloon began at 20 miles from town.

So Henry's balloon was farther form the town at the beginning.

Now let's find the slope/rate of change and compare then.

Henry's balloon: y-y1/x-x1 = 48-30/2 = 18/2 = 9

Tasha's balloon m: 8

9>8 Therefore henry was faster

Answer:

Step-by-step explanation:

What they are asking for here is where the y-values are negative in interval format. Intervals are x things only, no y's allowed. So the interval of (-infinity, -3) indicates an x value of negative infinity to an x value of -3. The y's are negative from an x value of negative infinity to an x-value of -3, then again from an x value of almost -1 to an x value of almost positive 1. So your choice is the last one listed there.

Step-by-step explanation:

Answer:

First we are going to try to find how many hours she worked on the fast food restaurant so you multiply 4.25 time 16 and x

10.50x + 4.25(16-x) =136.75

10.50x + 68 - 4.25x= 136.75

Then, you subtract 68 from both sides and subtract 4.25x from 10.50x

6.25x=68.75

Divide

X=11 that is how many hours she worked at the FAST FOOD RESTAURANT

Then 16-11 and that gives us how many hours she helped her aunt.

ANSWER: she worked 11 hours at the fast food restaurant and 5 hours helping her aunt

Step-by-step explanation:

Here, we are required to determine how many hours Kara worked at the fastest food restaurant and how many hours did she help her aunt clean the store.

First, we need to create a model for the work done and how much she earned.

The model is therefore in the form;

$10.50(x) + $4.25(16-x) = $136.75

To determine the no. of hours worked at the fast food restaurant, we have to evaluate the value of x.

Therefore;

x = 11

The number of hours worked by Kara in the restaurant is; 11hours.

The number of hours worked by Kara in her aunt's store is; (16 - 11) hours = 5hours.
