Answer: The answer is 4

Step-by-step explanation:

P, Q, and R are collinear points.

Q lies between P and R

Therefore ,

PR = PQ + QR

5x = 10 + 3x-2

5x - 3x = 8

2x = 8

x = 8/2

x =4

Answer:

Step-by-step explanation:

Because Bryce did 7/8 hours every day for 20 days,

7/8 hours is 52.5 minutes.

so then times 20, you will get 1050 minutes.

Then divided by 60(minutes per hour) you will get 17.5 hours,

which means she did 17 hours and 30 minutes in the first 20 days,

then you plus the last 1 hour per day for 10 days,

you will get 10 hours plus 17 hours and 30 minutes.

So Bryce have worked 27 and 30 minutes in september.

(I wish this could help you)

Answer:

27.5 hours

Step-by-step explanation:

Total hours:

20*7/8 + 10*1= 35/2+10=17.5+10= 27.5 hours

Answer:

42 Comedy, 49 Action, 21 Horror

Step-by-step explanation:

6 comedy : 7 action : 3 horror = 16 parts or if you think of it as a fraction, 16 is the denominator and the numbers for each ratios are the numerators

112 (the total)/16 = 7 movies per part

6 parts of comedy = 6 x 7 = 42

7 parts action = 7 x 7 =49

3 parts horror = 3 x 7 = 21

Another way to think of it is:

(ex. comedy)

6/16=x/112

(CROSS MULTIPLY HERE)

16x=672

x=42

Answer:

Cone A, Cone C, Cone B

Step-by-step explanation:

The volume of a cone is V=πr^2h/3 where V represents the volume, r represents the radius, and h represents the height.

That means the volume of cone A would be:

V = π * 5^2 * 6/3

V = π * 25 * 2

V = 50π

And the volume of Cone B would be:

V = π * 7^2 * 4/3

V = π * 49 * 4/3

V = 65.33π (about)

Lastly, the volume of Cone C would be:

V = π * 6^2 * 5/3

V = π * 36 * 5/3

V = 60π

65.33π > 60π > 50π

Therefore, Cone B has the largest volume, then Cone C, and, lastly, Cone A.

Answer:

1. 50

2. 12

Step-by-step explanation:

Answer:

2. 50 stamps

3. 12 minutes

Step-by-step explanation:

2. Darius had 15 stamps, then he ordered 3 rolls. You can determine how many he got from the rolls by subtracting the total from 15. 165 - 15 = 150.

Now we know that there were 150 stamps in the rolls Darius ordered. Divide 150 by 3 (3 rolls) to find the number of stamps in each roll!

150/3 = 50.

3. First, remember that 1 hour = 60 minutes.

We want to find how long America played soccer on Monday, which is the same amount of time she played on Tuesday and Wednesday as well. This means we can subtract Thursday and Friday's time from 60 minutes, then divide that time by 3, to find the time she played on Monday.

60 - 14 - 10

= 36 minutes

Now, we divide 36 minutes by 3 to get 12 minutes.

Answer:

t = 1

Step-by-step explanation:

16 - 2t = 5t + 9

1) First move 5t to the left side

16 - 2t - 5t = 9

2) Then move 16 over to the right side

-2t -5t = 9 - 16

3) simplify both sides

-7t = -7

4) divide both sides by 7

-t = -1

5) divide both sides by -1

t = 1

Answer:

the result of adding these two equations is

3x = 14

Step-by-step explanation:

We are given two equations

5x − y  = 6          eq. 1

−2x + y = 8        eq. 2

Add the like terms together

5x - 2x = 3x

− y + y = 0

6 + 8 = 14

So the result of adding these equations is

3x + 0 = 14

3x = 14

Bonus:

The value of x is

3x = 14

x = 14/3

Answer:

3x = 14

Answer:

The critical values of r are -0.708 and 0.708.

Step-by-step explanation:

A statistical test is being performed to determine whether there is any linear correlation between two variables.

The hypothesis can be defined as follows:

H₀: There is no  linear correlation between two variables, i.e. ρ = 0.

Hₐ: There is a significant linear correlation between two variables, i.e. ρ ≠ 0.

The test statistic is given as follows:

[tex]t = \frac{r\sqrt{n-2}}{\sqrt{1-r^{2}}}[/tex]

The degrees of freedom of the test is:

[tex]\text{df}=n-2=12-2=10[/tex]

The significance level of the test is, α = 0.01.

The critical values of r are:

[tex]r_{\alpha/2, (n-2)}=r_{0.01/2, (12-2)}=r_{0.005, 10}=\pm0.708[/tex]

*Use the r critical value table.

Thus, the critical values of r are -0.708 and 0.708.

From the 'r' table, the values of 'r' are -0.708 and 0.708.and this can be determined by using the hypothesis test.

Given :

The hypothesis test is performed in this problem. The null and alternate hypothesis is:

[tex]\rm H_0 : p=0\\[/tex]

[tex]\rm H_1:p\neq 0[/tex]

The t-statistics is given by:

[tex]\rm t =\dfrac{r\sqrt{n-2} }{\sqrt{1-r^2} }[/tex]

Degree of freedom is given by:

df = n - 2 = 12 - 2 = 10

The significance level for this test is [tex]\alpha = 0.01[/tex]

Now, the critical value r is given by:

[tex]\rm r_{\alpha /2,(n-2)}=r_{0.01/2,(12-2)}=r_{0.005,10} = \pm0.708[/tex]

So, from the 'r' table, the values of 'r' are -0.708 and 0.708.

the answer is c

Answer:

x = -3, and y = -3, or the ordered pair is (-3, -3)

Step-by-step explanation

To solve this system, you can use the elimination method:

First, write both equations down.

12x - 8y = -12

6x + 4y = -30

If you multiply the second equation by 2, you can eliminate x. Rewrite the first equation, and multiply the second one by 2:

12x - 8y = -12

12x + 8y = -60

Once added, you get the equation:

24x = -72

x = -3

Now, we just plug -3 into one of the equations and solve for y:

12x - 8y = -12

12(-3) - 8y = -12

-36 - 8y = -12

-8y = 24

y = -3

So, x=-3, and y=-3, or the ordered pair is (-3, -3)

Answer:

∠ FAB = 75°

Step-by-step explanation:

The external angle of a triangle is equal to the sum of the 2 opposite interior angles.

∠ FAB is an external angle, thus

13x - 3 = 3x + 2 + 55 = 3x + 57 ( subtract 3x from both sides )

10x - 3 = 57 ( add 3 to both sides )

10x = 60 ( divide both sides by 10 )

x = 6

Thus

∠ FAB = 13x - 3 = 13(6) - 3 = 78 - 3 = 75°

Step-by-step explanation:

To find the following product

[tex] \sqrt[3]{4} \times \sqrt{3} [/tex]

we can rewrite the radicals and then replace them into the multiplication, as follows:

[tex] \sqrt[3]{4} = 4^{\frac{1}{3}} = 4^{\frac{1}{3} \times \frac{2}{2}} = 4^{\frac{2}{6} = \sqrt[6]{16}[/tex]

[tex] \sqrt{3} = 3^{\frac{1}{2}} = 3^{\frac{1}{2} \times \frac{3}{3}}} = 3^{\frac{3}{6}} = \sqrt[6]{27} [/tex]

[tex] \sqrt[3]{4} \times \sqrt{3} = \sqrt[6]{16} \times \sqrt[6]{27} = \sqrt[6]{16 \times 27} = \sqrt[6]{432} [/tex]

Answer:

C edge 2021 :)

Step-by-step explanation:

Answer:

it is the second option. answer is x[tex]\leq[/tex]-8/3 or x>4

Step-by-step explanation:

we have the inequality 3x+8/x-4=0

we first multiply both sides by 4 the 4 cancels out on the left-hand side and  4*0 is 0 so we now have 3x+8=0 then we subtract both sides by 8 and get 3x=-8 then we divide both sides by 3 and get x=-8/3  

x[tex]\leq[/tex]-8/3 works in the original inequality

-8/3[tex]\leq[/tex]x[tex]\leq[/tex]4 does not work

x>4 does work
