Chicago to KC

d = ??

v = 440 knots

t = t - 3

KC to Chicago

d = ?? But it is the same distance as the givens above.

v = 110 knots

t = t hours

Equation

d = r * t

Solve

Since the distances are the same you can equate the r * t

440 * (t - 3) = 110 * t The numbers would be a lot smaller if you divided both sides by 110

[440 * (t - 3)] / 110 = 110 t / 110

4*(t - 3) = t Remove the brackets.

4t - 12 = t Subtract t from both sides

3t - 12 = 0 Add 12 to both sides

3t = 12 Divide by 3

t = 12/3

t = 4 The time to fly for the slower plane = 4 hours.

Solve for distance.

d = r * t

d = 110knots / hr * 3 hr

d = 440 knots. You should get exactly the same thing for t if you do not divide by sides by 110 knots

440 * (t - 3) = 110*t

440 f - 440 * 3 = 110*t

440t - 1320 = 110t Subtract 110t

440t - 110t - 1320 = 0

330t - 1320 = 0

330t = 1320

t = 1320 / 330

t = 4 Same answer.

Answer:

Hilda needs 64 ft² of tile

8601 in² will be uncovered post mounting

Step-by-step explanation:

Ar=10•6=60 ft²

At=[4•2]/2=8/2=4 ft²

total area=Ar+At=60+4=64ft²

......

Atv=31•57=1767 in²

Aw=(12•8)•(9•12)=10368 in²

Au=Aw-Atv=10368-1767=8601 in²

The sum of the volume of two rectangular prisms, box a and box b are 14.325cm cubed. Box a has a volume of 5.61cm.
Galina-37 [17]

The equation that could be used to determine the volume of Box B is (B = 14.325cm³ - 5.61cm³) and the volume of Box B is 8.715cm³.

This question is incomplete, the complete question is:

The sum of the volume of two rectangular prisms, box a and box b are 14.325cm cubed. Box a has a volume of 5.61cm.

a. Let B represent the volume of Box B in cubic centimeters. Write an equation that could be used to determine the volume of Box B.

b. Solve the equation to determine the volume of Box B

<h3>What is volume?</h3>

Volume is simply the amount of space that is enclosed within a container.

Given that;

  • Sum of the volume of two rectangular prisms A&B = 14.325cm³
  • Volume of Box A = 5.61cm³

a)

Let B represent the volume of Box B in cubic centimeters. The equation that could be used to determine the volume of Box B will be;

Sum of the volume of two rectangular prisms A&B = Volume of Box A + Volume of Box B

14.325cm³ = 5.61cm³ + B

B = 14.325cm³ - 5.61cm³

Hence, The equation that could be used to determine the volume of Box B is B = 14.325cm³ - 5.61cm³

b)

To determine the volume of Box B, we solve the equation.

B = 14.325cm³ - 5.61cm³

B = 8.715cm³

Hence, the volume of Box B is 8.715cm³.
