A. does 24 ft = 2in ?

Answers

No, your answer should be,

[tex]\Huge\boxed{288}[/tex]

To convert feet into inches, you multiply the length value by 12. Your mistake is you got it mixed-up. 24ft doesn't equal 2in, but 24in equals 2ft, because instead of multiplying 12, you divide by 12.

24ft → 288in

24 × 12 = 288

24in → 2ft

24 ÷ 12 = 2

Hence, 24ft doesn't equal 2in.

24 doesn’t equal 2.

Answers

Answer:

I'm pretty sure that the answers would go, Wrong, increased, 9 1/2 points, 6 5/8 points, dropped, 12 3/4 points.

Step-by-step explanation:

The reason why it would be wrong is because the amount of points lost was less than the total amount of points gained.

In week one and two the company gained 9 1/2 points and 6 5/8 points. When you add them together, you get 16 1/8 points.

In week three the company lost 12 3/4 points. If you multiply the fraction to change the denominator to 8, the mixed fraction becomes 12 6/8.

16 1/8 - 12 6/8 = 3 3/8

As you can see, there are still points left over.

In the fourth week, they ended up losing all of their points and then some more, but from my understanding it's just asking about the third week.

Hope that this helps!

10. Which equation below is equivalent to 3x + 2y = -2?
a. y = -2/3x – 5
b. y = 3/2x + 7
c. y = -3/2x - 1 d. y = 2/3x + 4
e. NOthing

Answers

Answer c, you have to put the equation in slope intercept form which is y=Mx+b so you would subtract the 3x and move it to the other side of the equal sign before the -2 so it would be 2y=-3x-2 then you would divide the 2 on both sides to separate the 2 from the y. -3x/2 is -3/2x 2/-2 is -1 so you answer would be C y= -3/2x - 1 Hope this makes since! Good luck!

Which expression is equivalent to 3(4m - 2) - 2(m + 5)

A. 10m - 16

B. 14m + 4

C. -16m + 10

D. 12m - 6

Answers

Answer:

A. 10m - 16

Step-by-step explanation:

First, distribute 3 to all terms within the corresponding parenthesis, and -2 likewise:

3(4m - 2) =

3 * 4m = 12m

3 * -2 = -6

3(4m - 2) = 12m - 6

-2(m + 5) =

-2 * m = -2m

-2 * 5 = -10

-2(m + 5) = -2m -10

Combine like terms:

12m - 6  -2m - 10

12m - 2m - 6 - 10

(12m - 2m) + (-6 - 10)

10m - 16

A. 10m - 16 is your answer.

~

Answer:

10 m - 16 (Answer A)

Step-by-step explanation:

We use distributive property to eliminate parenthesis:

12 m - 6 - 2 m -10

and now combine like terms:

[12 m - 2 m] - 6 - 10

10 m - 16

Therefore, answer option A.  is the correct one

Answers

Answer:

1 3/4 gallons of paint

Step-by-step explanation:

sorry if wrong

You need to find a common denominator I chose 28 so I multiplied 4 by 7 and that gives you 28 and you have to do the same thing to the top that you did to the bottom so I multiplied 11 by 7 as well which gave me a fraction of 77/28 then I multiplied 7 by 4 to get 28 and multiplied the top by 4 to get a fraction of 20/28 then I added 8 to 20/28 and to 77/28 to get 28/28 (the whole fence) and 85/28 (the paint you need to cover the whole fence) then I simplified my answer by seeing how many times 28 fit into 85 and it fits 3 times with a remainder of 1 so the simplified answer I got was 3 and 1/28 gallons of paint to cover the whole fence.

Answer:

x = -5

Step-by-step explanation:

In both questions you want to get the x alone.

1.

-3x + (-6) = 9

First you want to add 6 to both sides so you'll be left with:

-3x = 15

Next, you want to divide both sides by -3 and you'll get:

x = -5

2.

-4x + (-12) = 8

You want to do the same thing as the first one so you'll add 12 to both sides:

-4x = 20

Then, you will divide both sides by -4 and get:

x = -5

How much larger is the 8 in 8,237 than the 8 in 823.7?

Answers

Answer:Since the 8 in the first number is in the thousands place, its value it 8*1000=8000

8000 is ten times 800.

Step-by-step explanation:

The 8 in 8,237 is in the thousands place. On the other hand, the 8 in 823.7 is in the hundreds place.

8 • 1,000 = 8,000

8,000 is TEN times 800.

How to obtain real measurements from the ratio of two measurements?

Suppose the  real measurements were "a" and "b"

Then their ratio will be formed as

[tex]\dfrac{a}{b} = \dfrac{p \times x}{q \times x} = \dfrac{p}{q}[/tex]

where  is a common factor (not 1)

This shows that to get the real measurements from the given ratio, we need to assume to have some factor possibly cancelled from both the numerator and the denominator. Thus, a = px, b = qx

We are given the ratio as; 3:4

3: 4 x 2 = 6 : 8

3: 4 x 5 = 15 : 20

3: 4 x 3 = 9 : 12

Therefore, the equivalent ratio to the given to 3:4 are 6:8, 15:20 and 9:12

Answer:

1.) The height of the cone is 10 and the volume is 2355

2a.) Height 5= Volume 1177.5.

2b.) Height 30= Volume 7065

3.) (I'm not exactly sure because I haven't done this in a while.)

I guess 30= diameter

4.) 1 unit of height = 235.5 units of volume

Sorry if i messed up 3 or 4. I haven't calculated this stuff in a while.

Step-by-step explanation:

1.) It says the height of the cone on the horizontal ray and volume of the cone of the vertical ray.

2.) Divide 10 by 2 to get 5 height - Divide 2355 by 2= 1177.5

2b.) Multiply 10 by 3= 30 height - Multiply 2355 by 3= 7065

3.) r= √3× (V ÷ h) subtitute: r= √3× (2355 ÷ 3.14× 10)

simplify: r= 14.99... Diameter = 2 radius so about 30

4.) Divide 2355 by 10 to get the unit ratio. 1 unit of height is 235.5 volume.
