The Area of a rectangle is 216 square inches. if the perimeter is 60 inches find the lenght and width of the rectangle

Yuki888 [10]

Xy = 216
x = 216/y
2x + 2y = 60
2(216/y) + 2y = 60
432 + 2y^2 = 60y
2y^2 - 60y + 432 = 0
y = 18 , y = 12

if y = 12
x = 216/12
x = 18

length = 18
width = 12

A crowd of 50,000 fans is expected to attend the homecoming football game. if the typical vendor can serve 1,500 customers per h

Andre45 [30]

One vendor can serve 1500 customers per hour. in 4 hours he can serve 6000 customers & we have to serve 50000 fans so for this purpose we need 50000 / 6000 that is 8.••• vendors so in short we need 9 vendors at all so they can serve all the 50000 fans

14. What is the solution of the system? Use elimination. 9x + y = 30 6x - y = 15

klemol [59]

Answer:

x=90/16,y=-150/16

Step-by-step explanation:

Simultaneous equation and we are to use elimination method

9x+y=30...(1)

6x-y=15..(2)

Add (1) and (2)

16x=15

Divide both sides by 16

x=15/16

Then substitute the value of x into (2)

6(15/16)-y=15

90/16-y=15

Substrate 15 from both sides

90/16-y-15=0

Add y to both sides

90/16-15=y

Lcm for only the left side which is 16

90-240/16=y

-150/16=y

Therefore x is 90/16 and y is -150/16

Bob drives a truck for a soft drink company. His truck is filled with 15 oz cans and 70 oz bottles. Let C be the number cans and

Mekhanik [1.2K]

Answer:

Using ounces, the inequality should be:

15c + 70b < 112,000

Using pounds, the inequality should be:

0.9375c + 4.375b < 7,000

Step-by-step explanation:

1. Let's review the information provided to us to answer the question correctly:

Weight of a can of soft drink (c) = 15 ounces

Weight of a bottle of soft drink (b) = 70 ounces

The truck mist be carrying less than 7,000 pounds

2. Find the inequality describing this.

Let's recall that 1 pound = 16 ounces and 1 ounce = 0.0625 pounds

c = Number of cans in the truck

b = Number of bottles in the truck

Upon saying that, we can write the inequality either using ounces or pounds, this way:

Using ounces, the inequality should be:

15c + 70b < 7,000 * 16

15c + 70b < 112,000

Using pounds, the inequality should be:

15 * 0.0625c + 70 * 0.0625b < 7,000

0.9375c + 4.375b < 7,000

Show your solution read the instructions

Annette [7]

Answer:

1) $5r + 2 < s$

2) $12t + 6s < 960$

3) $p - q > 30$

Step-by-step explanation:

1) Length of a ruler = r

Height of Shiela = s

According to the question ,

5 times the length of a ruler increased by 2 .

⇒ $5r + 2$

Also , 5r + 2 is less than height of Shiela.

Hence , the linear inequality is ⇒ $5r + 2 < s$

2) Let the cost of each t-shirt be 't' & cost of each short be 's'.

⇒ Cost of dozen of t-shirts = 12t and Cost of half a dozen shorts = 6s

According to the question ,

12t & 6s is not greater than Php 960.

Hence the linear inequality is ⇒ $12t + 6s < 960$

3) Let the number of Php 100-peso tickets be 'p' and let the number of Php 50-peso tickets be 'q'.

According to the question ,

Difference of p & q is not less than 30

Hence the linear inequality is ⇒ $p - q > 30$
