Hello! This is simple. All you have to do is know the conversions. So, there are 12 inches in a foot, there are 36 inches in a yard, and there are 3 feet in a yard. So, we will start with feet. If there are 12 inches in a foot then you simply divide 42 by 12 which gives you 3.5 feet. Then you have to add the other 2.5 feet to it which gives us 6 feet. Lastly, you want to convert the yards into feet which is 4.5 feet. We just add all that together which gives us: 10.5 feet! 

Now let's do inches. So we leave the 42 alone since it is already in inches. Remember there are 12 inches in a foot, and there are 2.5 feet. So that gives us 30 inches. 42+30. Then we have 1.5 yards and there are 36 inches in a yard, so we divide which gives us 54 inches. So we have: 42+30+54= 126. So there are 126 inches.

Now that we have those out of the way, let's do yards. 2.5 feet in yards is 0.8 yards. So we have 0.8. Then we have 42 inches which is 3.5 feet. So then we figure that 3.5 is 1.1 yards so then we have 0.8+1.1+1.5= 3.4 yards!

So you get: 10.5 feet, 126 inches, and 3.4 yards!

I hope this helped!

Find the value of c that completes the square
Kitty [74]

Answer:

c = 64

Step-by-step explanation:

Given

x² - 16x + c

To complete the square

add ( half the coefficient of the x- term )² to x² - 16x

x² + 2(- 8)x + 64

= (x - 8)²

Thus

x² - 16x + 64 = (x - 8)² ← a perfect square

with c = 64

Is anyone willing to help me with this? I tried adding this and still no answer. Please help..
GaryK [48]

Answer:   C. (-4, -2)

<u>Step-by-step explanation:</u>

First, eliminate one of the variables and solve for the remaining variable:

2x - 5y = 2      →    3(2x - 5y = 2)      →     6x - 15y = 6

3x + 2y = -16   →  -2(3x + 2y = -16)    →  <u> -6x - 4y = 32</u>

                                                                     -19y = 38

                                                                         y = -2


Next, replace "y" with -2 into either of the original equations to solve for x:

2x - 5y = 2

2x - 5(-2) = 2

2x + 10 = 2

2x         = -8

 x          = -4

                                       x = -4,  y = -2

<u>Check:</u>

Plug in the x- and y-values into the other original equation:

3x + 2y = -16

3(-4) + 2(-2) = -16

-12  +  -4     = -16

      -16         = -16   \checkmark

In which number does the digit 4 have a value that is 10 times as great as the value of the digit 4 in 348,971? 284,796 or 327,4
Doss [256]

Answer:

The number is 492,875.

Step-by-step explanation:

Given:

A number that is = 348,971

Place value of 4 = 40,000

Place value is ten thousands.

We have to identify the number where the place value of 4 is 10 times of the given number.

Numbers given:

284,796 or 327,498 or 492,875 and 742,186.

Lets see the place value of 4 in each of the number.

⇒

  • 284,796 place value of 4 is 4,000.
  • Place value of 4 is thousands.

⇒

  • 327,498 place value of 4 is 400 .
  • Place value of 4 is hundreds.

⇒

  • 492,875 place value of 4 is 4,00,000.
  • Place value of 4 is hundred thousands.

⇒

  • 742,186 place value of 4 is 40,000.
  • Place value of 4 is ten thousands.

Notes:

Ten thousands multiplied with ten is hundreds thousand.

⇒ 10,000\times 10 =1,00,000

So,

The number which has digit 4 as hundred thousands place values is 492,875.
