Jo has an appointment at 3pm. She has to travel 21 miles and will drive at an average speed of 30 mph. To arrive exactly on time, what time should she leave? Give your answer as a time on the 24-hour clock

Answer:

33m

Step-by-step explanation:

If the ratio of the new length to the old length is 11:8 (simplified ratio)

I like to set up a proportion, like this,

x/24 = 11/8, where x is the undefined new length

x*8 = 24*11 (cross multiply)

8x = 264 (multiply)

x = 33 (divide 8 by both sides)

The new length is 33m.

Hope I helped! Good Luck!

Answer:

33m

Step-by-step explanation:

The 8 part of the ratio refers to the old length 24m

Divide by 8 to find the value of one part of the ratio

24m ÷ 8 = 3m ← value of 1 part of the ratio, then

11 parts = 11 × 3 = 33m

Thus

33m : 24m = 11 : 8

Option B

Step-by-step explanation:

36x^3-x=0,

x(36x^2-1)=0,

x((6x)^2- (1)^2)=0,

x(6x-1)(6x+1)=0

Your solution would be (6x-1)(6x+1) accordingly.

Answer:

3/8 because 3/8 as a percent is 37.5 percent

Step-by-step explanation:

Answer:

3/8 is greater

Step-by-step explanation:

3/8 as a percent is 37.5

37.5% > 25%

Therefore 3/8 is greater

Tip:

Covent one to the other unit

like 3/8 to a percent or 25% as a fraction.

But if you are looking for which is greater in fraction form then 25%

Answer:

1.  144  2. 16 3. 1   4. 3x-6  

Step-by-step explanation:

So think of this as a function in a function.  So you work from the inside to the outside.  So for problem 1, we start with f(4)) [you read it "f of 4"] so what is the solution when x = 4, since f(x) means the function of x so f(4) means 'the function of 4' inside f(x).  

Since f(x) = 3x then f(4) = 3(4) [notice how you substitute the 4 everywhere you see a letter x]

so f(4) = 12, now you work the next part h(f(4)) since f(4)=12 then h(12)

So take the h(x) function which is h(x) = [tex]x^{2}[/tex] then h(12) = [tex]12^{2}[/tex] so h(12) = 144

Answer:

F=90

D=37

E=53

f=18.3

d=11

e=14.6

Step-by-step explanation:

Triangle Sum Theorem means 180-37-90=E.  So, E=53 degrees.

Sin(37)=[tex]\frac{11}{f}[/tex]

fsin(37)=11

f=[tex]\frac{11}{sin(37)}[/tex]

f=18.3

Tan(37)=[tex]\frac{11}{e}[/tex]

etan(37)=11

e=[tex]\frac{11}{tan37}[/tex]

e=14.6

Make sure your calculator is in DEGREE mode.

Answer:

i dont seeeeeee an x

Step-by-step explanation:

Answer: The first step would be to multiply the first equation by 3 and the second by 2 so you can eliminate x.

Answer:

(2, 0 )

Step-by-step explanation:

Given the 2 equations

2x + 3y = 4 → (1)

3x - 7y = 6 → (2)

Multiplying (1) by 3 and (2) by - 2 and adding the result will eliminate x

6x + 9y =  12 → (3)

- 6x + 14y = - 12 → (4)

Add (3) and (4) term by term to eliminate x

0 + 23y = 0

23y = 0

y = 0

Substitute y = 0 into either of the 2 equations and solve for x

Substituting into (1)

2x + 3(0) = 4

2x = 4 ( divide both sides by 2 )

x = 2

solution is (2, 0 )

Answer:

  h(0) = 10

  h(4) = 16

Step-by-step explanation:

The second part of the function definition applies when x=0.

  h(x) = 2x^2 -3x +10

  h(0) = 0 + 0 + 10 = 10

__

The third part of the function definition applies when x=4.

  h(4) = 2^4 = 16

Using correlation coefficients, it is found that the correct option is:

B The scatter plot would closely resemble a straight line with a negative slope. The data has a strong, negative correlation, but causation cannot be determined.

In this problem, the correlation coefficient of −0.91, meaning that there is a strong inverse relation between the location of the game and the team's winning percentage, that is, the team is more likely to win on the road, hence, option B is correct.

Answer:

y=2.3x

Step-by-step explanation:

Answer:. 38 and 52

It is given here that

angle FKY = 90.

we know angle. FKG + GKY. = FKY

so,. (7c + 24) + (5c + 42) = 90

12c + 66 = 90

12c = 90 - 66

12c = 24

c= 24/12

c = 2

then angle is

7*2+24 = 38

5*2 + 42 = 52

Answer:

Perimeter = 54

Step-by-step explanation:

Since AC = RP, then the following also applies:

AB = RB

CB = PB

So, in order to determine this, you first need to find a common ratio in order to find the missing side of PB which you need for the perimeter.

To determine the ratio you do the following:

AB = 21 (14 + 7)

RB = 7

21: 7   = 3: 1

This means in finding a smaller side you can divide by the value 3 to find it.

It also means that side CP is 2/3 of the value of CB which means that we need 1/3 of the value left in order to determine PB:

CP = 10 = 2/3, which means 1/3 is 5, so

PB = 5

Therefore: CB = 15

Perimeter = CB + AC + AB

15 + 21 + 18 = 54
