Please answer question 12.

Answer:

54j + 72 + 9j and 63j + 72

Step-by-step explanation:

I just simplified it

So 9(6j + 8 + 1j) can be distributed to (9)(6j) + (9)(8) + (9)(1j) which equals 54j + 72 + 9j because 9*6j = 54 , 9*8 = 72 , and 9*1j = 9j

54j + 72 + 9j can also equal 63j + 72 because 54j + 9j = 63j

I hope this helped and I hope this is close to what you wanted heh :)

It took each girl 1/8 hour to print their project.

Step-by-step explanation:

1/2 hour = 30 minutes

30 minutes / 4 girls = 7.5 minutes for each girl to print their project

7.5 minutes / 60 minutes in an hour = 0.125 or 1/8 hour

Answer:

x is 23

Step-by-step explanation:

cause it is an 180 angle so 180-93=87

87 -18 =69

3x=69

x=23

Answer:

Step-by-step explanation:

in order to find x

(3x+18)° + 93°=180°

⇒3x+18=180-93

⇒3x=180-93-18

x=69/3

x=23

and there we go X = 23

hope it helps :)

have a great day!!

Answer:

Step-by-step explanation:

in the first one 2,4,6,and 8 are equal meaning they all equal to 75. the other angles 1,3,5,and 7 equal 105 because 180 - 75 = 105

for the other ones i'm not sure srry

Answer:

471.24 inches is the volume of the cylinder.

Basically, since the diameter of the cylinder is 10 inches the radius will be 5 inches.

The formula to figure out the volume of a cylinder is V=πr2h.

So using that formula the volume of the cylinder is 471.24 inches.  

Answer: 3000 Kelvin

Step-by-step explanation

Let the surface temperature of the red giant star = x

Surface temperature of a white dwarf star = 4x

4x = 1.2 × 10^4 K

    = 1.2 × 10,000 K

    = 12,000 K

4x = 12,000 K

x = 12000 ÷ 4

  = 3,000 K

Answer:

108 degrees

Step-by-step explanation:

By the Exterior Angle Theorem:

(2x + 1) + 63 = 5x -2

2x + 64 = 5x - 2

66 = 3x

22 = x

Now, we can plug the value of x back into the expression that represents the exterior angle to find the measure of the exterior angle:

5(22) - 2

110 - 2

108

The answer is 108 degrees. (I'm sorry your question was answered so late; I hope you got the right answer when you solved it!)

Answer:

Y=15x i the answer to this equation.

Step-by-step explanation:

Answer:

y = 15x

Step-by-step explanation:

To write the equation, you'd need to find the slope:

[tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} } \\\\\frac{60-15}{4-1} \\\\\frac{45}{3} \\\\15[/tex]

The y-intercept is 0

The correct weight to the nearest 1/8 pound from the considered image is 3.55 pounds. In reduced fraction form, it is 71/20 pounds approx.

For conversion from decimal to fraction, we write it in the form a/b such that the result of the fraction comes as the given decimal. Usually, to get the decimal of the form a.bcd, we count how many digits are there after the decimal point (if its finite), then we write 10 raised to that many power as denominator, and the considered number without any decimal point as numerator.

For example:

[tex]0.99 = \dfrac{99}{10^2} = \dfrac{99}{100}[/tex]

(10 raised to power k = 1 followed by k zeroes)

Let we have to add two fractions as:

[tex]\dfrac{a_1}{b_1} + \dfrac{a_2}{b_2}[/tex]

Then we will find Lowest Common Multiple (LCM) of  [tex]b_1[/tex] and [tex]b_2[/tex]. That will help to make the denominators same.

Once the denominators become same, the numerators can add up directly, giving us the final result of addition.

For this case, we can see from the image that:

Weight shown = 3 pounds + half more pound + half of 1/10 pound more approx. (as the weight hand is approx between 5 and 6 minor ticks after the big 3 pound mark). In each minor mark, one pound is divided in 10 parts, so each minor tick adds up 1/10 of a pound. Half of 1/10 shows that after 5, the hand is not exactly on 6 but sort of in between them, so approximately half.

Thus, weight shown ≈ 3 + 0.5 (half is written 0.5 too) + 1/10 of 0.5 pounds

= 3 + 0.5 + 0.5/10 = 3.5 + 0.05 = 3.55 pounds

Thus, the weight is approx 3.55 pounds.

Converting it to fraction, we get:

[tex]3.55 = \dfrac{355}{100} = \dfrac{5 \times 71}{5 \times 20} = \dfrac{71}{20}[/tex] pounds.

Thus, the correct weight to the nearest 1/8 pound from the considered image is 3.55 pounds. In reduced fraction form, it is 71/20 pounds approx.
