8. Which pair of lines must be parallel?
A. p and r
B. g and s
C. p and s
D. q and r ​

Answer:

The sum of the measures of the exterior angles of a convex polygon is 360 degrees.

Step-by-step explanation:

- 4x + 3y = 15

2x + y = -5

I multiply x 3 the second equality

we will get

- 4x + 3y = 15

6x + 3y = - 15

difference of the 2 equalities

- 4x - 6x + 3y - 3y = 15 - (-15)

- 10x = 30

x = -3

so   - 4*(-3) + 3y = 15

3y = 3

y = 1

check

- 4 * (-3) + 3 * 1 = 12 + 3 = 15

Answer:

[tex]h = 5.73[/tex]

Step-by-step explanation:

Formula: [tex]V = \pi r^{2} h[/tex]

[tex]2178 = \pi (11)^{2} h[/tex]

[tex]2178 = 121\pi h[/tex]

[tex]2178 = 121 (3.14) h[/tex]

[tex]2178 = 379.94h[/tex]

[tex]h = 5.73[/tex]

Step-by-step explanation:

we don't know what level it was originally at so well use a variable for the unknown number. If you take 6 inches and do that 6 times for each month you will have 36 inches lost so w= water i = inches

w-(6i x 6) = 36

Answer:

265

Step-by-step explanation:

because she had 500 and now she has 765 so he gave her 265

Answer:

265

Step-by-step explanation:

Because before her Uncle visited she had 500 cents and he gave her a total of ? cents she now has 765.

Meaning what = 765 when you add it to 500.

500 + ?=765. we know 500 + 200=700 but she has 65 more than 700 so s you add that to our answer we get 765.

 5 0 0

 2 6 5

+______

   7    6  5=765

Answer:

522 times

Step-by-step explanation:

a peach chew was chosen 6 out of 23 times so we can create a proportion out of 2000 based on that ratio:

'p' = times peach is chosen out of 2000

6/23 =p/2000

cross-multiply to get:  

23p = 12000

p = 12000/23

p = 522 times

Answer:

522 times

Step-by-step explanation:

From this experiment, Skylar selects a peach chew 6/23 of the time. 6/23*2000=522. This works because 6/23 is the amount of chance Skylar has of selecting a peach chew if she selects one chew. If she selects 2000 chews, therefore, her odds of getting a peach chew would mean that she would get about 522 peach chews.

Answer:

D) 90 Days

Step-by-step explanation:

dredge 1 min = 3 people days

when I say people days, I mean 3 people working one day

multiply each side by 60 to get the desired 60 min of dredge:

dredge 60 min = 180 people days

As we currently have this set up, it will take 180 people, 1 day to do the same amount of work as 60 min of dredge, but we only want 2 people.  This means we need to divide the people days by 2 to get how many days are needed for 2 people, thus:

dredge 60 min = 2 people for 90 days

Answer:

The slope of the model is [tex]m = 2\,\frac{USD}{yr}[/tex].

The value of the slope indicates that the average cost of a hair cut is increased by 2 US dollars each year.

Step-by-step explanation:

We have to notice that given function is a linear function, that is, a first order polynomial, whose standard form is described below:

[tex]y =m\cdot x + b[/tex]

Where:

[tex]m[/tex] - Slope, dimensionless.

[tex]x[/tex] - Independent variable, dimensionless.

[tex]y[/tex] - Dependent variable, dimensionless.

[tex]b[/tex] - y-Intercept, dimensionless.

In this case, we use the linear function [tex]y = 2\cdot x + 28[/tex], where [tex]x[/tex] is the time after 2000, measured in years, and [tex]y[/tex] is the average cost of a hair cut. The slope of the model is [tex]m = 2\,\frac{USD}{yr}[/tex].

The value of the slope indicates that the average cost of a hair cut is increased by 2 US dollars each year.

You cant see the equation

Step-by-step explanation:

The probability  that the dart lands inside the square but not on the circular dartboard is 0.215

The chances of the happening of any event are called the probability.

The dartboard is in the form of a square and the circle is inscribed in it

The area of the dartboard is  [tex]a_d=54\ inch^2[/tex]

Since the circle is inscribed on the dashboard so the diameter of the circle will be the length of the square  

[tex]a_d=s^2=64[/tex]

[tex]s=\sqrt{64}=8\ inch[/tex]

Thus the diameter of the circle

[tex]d=8\ \ \ r= \dfrac{8}{2} =4 \ inches[/tex]

Now we will calculate the area of the circle

[tex]a_c=\pi r^2[/tex]

[tex]a_c=\ 3.14\times 4^2=50.24\ inch^2[/tex]

The area of the square outside the circle will be the difference of the area of the square and the area of the circle

[tex]64-50.24=13.76\ inch^2[/tex]

Now to find out the probability of the dart hitting outside the circle will be calculated as.

[tex]\rm Probability = \dfrac{Area \ outside \ circle }{Area \ of \ square}[/tex]

[tex]P= \dfrac{13.76}{64} =0.215[/tex]

Thus the probability  that the dart lands inside the square but not on the circular dartboard is 0.215

Step-by-step explanation:

Find two quantities that when differed to 43, they also multiply to 294. Those will be 6 and 49. The TINIER quantity gets the minus symbol because the B-value is 43, therefore 49 gets the plus symbol, leaving 6 with the minus symbol. In extension, sinse we have a leading coefficient greater than one, we need to take extra procedures. Here is how it is done:

Answer:

0.52grams of dissolved solids.

Step-by-step explanation:

; a 50-milliliter water sample has just 13 milligrams of dissolved solids. If Ernesto fills a 2-liter bottle from one of the water fountains at his school, how many grams of dissolved solids would his bottle have

50ml = 13mg of dissolved solids

1 litre = 1000 millilitres

2 liter = 2 × 1000 = 2000millilitres

50ml = 13mg

2000ml =

Cross Multiply

2000ml × 13m/50ml

= 520mg of dissolved solids.

We are to convert our final answer to grams

= 1 milligram = 0.001 gram

520 milligram =

520 mg × 0.001g/1 mg

= 0.52 grams of dissolved solids

Answer:

constant-4

variable-x

coefficient-9

Step-by-step explanation:

Coefficient- the number being multiplied by a variable

Variable- the unknown, usually 'x'

Constant- the number that is all by itself.

Answer:

(4, -3)

Step-by-step explanation:

Since we know that X = 4, when can set X = 4 in the other equation in order to solve for Y

2x - 4y = 20

2(4) - 4y = 20

8 - 4y = 20

-8           -8

-4y = 12

-4y/-4 = 12/-4

y = -3

Since we already know X = 4, the intersection point or solution to the System is (4, -3)

Answer:

71

Step-by-step explanation:

If a decimal needs to be rounded to a whole number, you need to refer to the tenths place in the decimal. In this case, that is "5" and in math, when rounding, if it is 5 or more, you round up to the next whole number. If it is 4 or less, you round down. So 70.5 rounded to the nearest whole number is 71. :)
