A rectangular parking lot has an area of 43,000 square feet. What is the length, x, of the parking lot if the width is 330 feet

lesantik [10]

Answer:

Length: 430

Width: 100

Step-by-step explanation:

Length : x

Width: x - 330

Area = 43000

Area = length * width

43000 = x (x - 330)

43000 = x² - 330x

x² - 330x - 43000 = 0

x² - 430x + 100x - 43000 = 0 // Doing factorization

x (x - 430) + 100 (x - 430) = 0

(x+100)(x-430) = 0

x + 100 = 0

x = -100 (Since the length can not be negative)

x - 430 = 0

x = 430(This is the length)

Width: x - 330 = 430 - 330 = 100

Proof : 430 * 100 = 43000

What number is 20 less than 150% of 80

patriot [66]

Answer:

100

Step-by-step explanation:

"What number" means a variable, like x.

"Is" means equals.

"Less than" means subtracted from.

Percent means out of 100.

"Of" means multiplication.

x = (150/100) 80 - 20

x = 120 - 20

x = 100

Together, teammates Pedro and Ricky got 2685 base hits last season. Pedro had 279 more hits than Ricky. How many hits did each p

ANTONII [103]

Answer:

2685-279=2,406

2,406÷2=1,203

Step-by-step explanation:

Ricky hit 1,203. because Pedro hit 279 so subtract it from 2685 and then divide by 2 and then you get Ricky's and you also get pedros if you add 1203 and 279 which gives you 1482.

You are competing in a race. The table shows the times from last year's race you want your time to be last year's median time wi

aleksandr82 [10.1K]

Answer:

$27\leq x \leq37$

Step-by-step explanation:

Let's arrange the numbers from least to greatest:

20, 25, 27, 28, 31, 32, 32, 38, 40, 40, 42, 48

The median is the "middle" number when arranged from least to greatest.

There are 12 numbers, so the middle number would be "average" of 6th and 7th terms.

6th term = 32

7th term = 32

Average = (32+32)/2 = 32

Hence, median = 32

Absolute deviation of 5 minutes means 5 minutes less or greater than the median, 32.

So, 32 - 5 = 27 & 32 + 5 = 37

Hence $27\leq x \leq37$
