If l=3, w= 3, and h= 5, what is the volume of this box

ArbitrLikvidat [17]

Answer and Step-by-step explanation:

To find the volume, we multiply the length by the width by the height for a rectangular prism (aka the box).

length = l = 3

width = w = 3

height = h = 5

Now, we multiply each together.

3 × 3 × 5

9 × 5

The volume of the box is 45.

Uni made a model of a 1970 Ford Mustang using a scale of .5 inches = 9 in. If the actual car is 15 ft long, how long is the mode

kykrilka [37]

Answer:

The model car is 10 inches long

Step-by-step explanation:

To solve this question, we use conversion of units

Feet to inches.

Each feet has 12 inches.

The car is 15ft long.

So the car has 15*12 = 180 inches.

.5 inches = 9 in.

Rule of three

.5 inches - 9 inches

x inches - 180 inches

$9x = 180*0.5$

$9x = 90$

$x = \frac{90}{9}$

$x = 10$

The model car is 10 inches long

Ma. Lott’s works at a music store. Last week she sold 6 more than 3 times the number of CDs that she sold this week. Ms. Lott’s

Contact [7]

Answer:

$x=3y+6$

$x+y=110$

The number of CDs sold last week was 84 and the number of CDs sold this week was 26

Step-by-step explanation:

Let

x ---> number of CDs sold last week

y ---> number of CDs sold this week

we know that

Last week she sold 6 more than 3 times the number of CDs that she sold this week

$x=3y+6$ ----> equation A

Ms. Lott’s sold a total of 110 CDs over the 2 weeks

$x+y=110$ ----> equation B

Solve the system by substitution

substitute equation A in equation B

$3y+6+y=110$

solve for y

$4y+6=110\\4y=110-6\\4y=104\\y=26$

Find the value of x

$x+26=110\\x=110-26\\x=84$

therefore

The number of CDs sold last week was 84 and the number of CDs sold this week was 26
