Answer 1

Answer:

the ans is 5

Step-by-step explanation:

2j+5=3+2j+2 cancel equal terms which is 2j

so what we have left is

5=3+2

5=5

so 5 is the ans

Answer 2

Answer: infinity many solutions

Step-by-step explanation:

2j + 5 = 3 + 2j + 2

Combine numbers in the right side

2j + 5 = 2j + 5

Minus the smallest j from both side in this case u get rid of both j’s which mean -2j

5 = 5

Divide by 1 or -5

Which mean we get 5 = 5 or 0 = 0

6(x + 2) is simply 6x + 12

Do 12 + 7

You will get 19.

Now put that together.

6x + 19, which is option 3

Hope this helped! :D
it’s 6x + 19
because you do 6(x + 2) u multiply the 6 times the x which is 6x and then 6 x 2 which is 12 so ur equation would be 6x + 12 + 7 so you just add 12 and 7 which is 19

Choose all of the correct statements.

Answers

Answer:

1. The diameter is 2 times the Lenght of the radius.

2. C = πd

3. π = C/d

4. d = C/π

5. The circumference is 3.14 times the diameter.

Step-by-step explanation:

Diameter (d) of a circle is 2 times the radius (r). Mathematically, it is written as:

d = 2r

From:

d = 2r

Divide both side by 2

r = d/2

The radius is half the diameter.

Circumference (C) of a circle is given by:

C = 2πr

C = π2r

Recall:

d = 2r

C = πd

C = πd

Divide both side by d

π = C/d

C = πd

Divide both side by π

d = C/π

C = πd

π = 3.14

C = 3.14 × d

Thus, the circumference is 3.14 times the diameter.

SUMMARY:

The correct statement from the above illustration is given below:

1. The diameter is 2 times the Lenght of the radius.

2. C = πd

3. π = C/d

4. d = C/π

5. The circumference is 3.14 times the diameter.

Tanya is paid an hourly rate. One week she earned $157.50 by working 30 hours. If she works 35 hours the next week, how much will she earn?

Answers

Answer:

183.75

Step-by-step explanation:

157.50

÷30

=5.25

×35

=183.75

Answer: $183.75

Step-by-step explanation: You divide $150.50 by the number of hours worked, 30 hours, to find the hourly rate. Then, you multiple the hourly rate by 35 hours.  

[tex]$157.50/30 hours = $5.25/hour \\$5.25/hour * 35 hours = $183.75[/tex]

Students surveyed boys and girls separately to determine which sport was enjoyed the most. After completing the boy
survey, it was determined that for every 3 boys who enjoyed soccer, 5 boys enjoyed basketball. The girl survey had a
ratio of the number of girls who enjoyed soccer to the number of girls who enjoyed basketball of 7:1. If the same
number of boys and girls were surveyed and 90 boys enjoy soccer, how many girls each sport?



Please help me and show how to solve this the best answer will get brainlesest

Answers

okay, let's go!
1. for the boys, 3 soccer is 5 basketball (in a group of 8 students).
2. for the girls, 7 soccer is 1 basketball (in a group of 8 students)
3. the question mentions 90 boys like soccer, which means we increased the number of boys surveyed 30x, since 3 times 30 is 90. now, we need to increase the girl numbers by 30 as well, giving us 210 girls who like soccer for every 30 who like basketball.

Patty's Pavers has determined that a paver measuring 5 inches long has a z-score of +1 and a paver measuring 5.25 inches long has a z-score of +2.

Hi! I need Help!
What is the mean length of the pavers produced at Patty's Pavers?

4.25 inches
5.25 inches
4.75 inches
5.75 inches

Thank you!

Answers

Answer:

4.75

Step-by-step explanation: given x=5 inches Z-score =1 let 'X' be the variable in normal distribution z=+1 when x=5 inches.

The mean length of the pavers produced at Patty's Pavers is 4.75 inches. Thus, the correct option is C.

What is Z-score?

A Z-score helps us to understand how far is the data from the mean. It is a measure of how many times the data is above or below the mean. It is given by the formula,

[tex]Z = \dfrac{X- \mu}{\sigma}[/tex]

Where Z is the Z-score,

X is the data point,

μ is the mean and σ is the standard variable.

The Z-score of +1 is,

(x-μ)/σ = 1

(5-μ)/σ = 1

5 - μ = σ

The Z-score of +2 is,

(5.25-μ)/σ = 2

(5.25 - μ)/σ = 2

5.25 - μ = 2σ

Substitute the value of the 'σ', therefore, standard deviation from the above,

5.25 - μ = 2(5 - μ)

5.25 - μ = 10 - 2μ

5.25 - 10 = -2μ + μ

μ = 4.75

Hence, the mean length of the pavers produced at Patty's Pavers is 4.75 inches. Thus, the correct option is C.
