Which answer choice correctly identifies the missing information in the problem? Joey and Kirk are in the 6th grade. Kirk is 5 f
user100 [1]

Answer:Kirk is taller than Joey by 8 inches

Step-by-step explanation:

Step 1

Kirk's height is given as  =5 feet 4 inches tall.

Joey's  height 4 feet 8 inches tall

Difference in height = 5 feet 4 inches

                                    - 4 feet   8 inches

                                 =

Step 2

Bear in mind that 12 inches = 1 feet . Now,8 cannot be subtracted from 4 , so we borrow 1 feet from 5feet,  which is equivalent to 12 inches and add to inches  so it becomes

4 feet  (12+4)inches     =                   4 feet     16inches

- 4 feet   8 inches                             - 4 feet   8 inches

                                                     =                   8 inches

Therefore Kirk is taller than Joey by 8 inches

Hi!

---------------------------------------------------------------------------------------------

Area of a triangle = (base * height)/2

Area of a square = (side)^2

---------------------------------------------------------------------------------------------

QUESTION 1: Determine the area of the triangular face.

\frac{bh}{2}

32(20)/2

640/2

320

<u>The triangular face is 320 square feet.</u>

---------------------------------------------------------------------------------------------

QUESTION 2: Determine the surface area of the entire figure.

a^2

32^2

1024

<em>Now, add the 4 triangular faces to the area of the square face.</em>

1024+320(4)

1024+1280

2304

<u>The total surface area is 1204 square feet.</u>

Find the dimensions of the regular corral split into 2 pens of the same size producing the greatest possible enclosed area given
mrs_skeptik [129]

Answer:

Length = 225 ft

Width = 150 ft

Step-by-step explanation:

If L is the length and W is the width, then:

900 = 2L + 3W

A = LW

Solve for W in the first equation:

3W = 900 − 2L

W = 300 − ⅔ L

Substitute into the area equation:

A = L (300 − ⅔ L)

A = 300L − ⅔ L²

Use calculus to find dA/dL and set to 0, or use the formula for vertex of a parabola.

Using calculus:

dA/dL = 300 − 4/3 L

0 = 300 − 4/3 L

L = 225

Using vertex formula:

L = -b / (2a)

L = -300 / (-4/3)

L = 225

Find the width:

W = 300 − ⅔ L

W = 150

You got the right answers, but the problem says to assume that the length is greater than the width.

I drove 380 miles using 14 gallons of gas. At this rate, how many gallons of gas would I need to drive 418 miles?
ser-zykov [4K]

Answer:

15.4 gallons .

Step-by-step explanation:

The rate of gas used  = 380/14 = 27.14 gallons per gallon.

So for each gallon used  you drive 27.14 miles.

So number of gallons used when travelling 418 miles = 418/27.14

= 15.4 gallons .
