the length of a rectangle is 6 meters less than twice the width. The area of the rectangle is 140m². Find the dimensions of the rectangle.
Answers
Answer:
Here's what we know:
A = Lw (Area is length times width)
L = 2w + 6 (length is twice the width plus 6)
A = 140 (Area is 140 m2)
Plug in the variable values:
140 = w(2w + 6)
Distribute:
140 = 2w2 + 6w
Subtract 140:
2w2 + 6w - 140 = 0
Factor out a 2:
2(w2 + 3w - 70) = 0
Divide both sides by 2:
w2 + 3w - 70 = 0
(w + m)(w - n)
When we factor out the quadratic, we know it's going to be a +/- situation because the c value in the quadratic is negative, and the two numbers are going to be three away, the plus next to the 3 meaning that the larger number is going to be positive:
(w + 10)(w - 7) = 0
w = -10, 7
We can't have a negative length, so we can toss out the -10, leaving us with w = 7 meters.
L = 2 * 7 + 6
L = 14 + 6
L = 20
Check:
140 = 20 * 7
140 = 140
equation 2 is 140= W * L
L=10
W=8

In a wildlife preserve, a random sample of the population of 150 raccoons was caught and weighed. The results, given in pounds, were 17, 19, 20, 21, 23, 27, 28, 28, 28 and 32. Jean made the inference, "the average weight of the raccoon population is 25 pounds". Is this statement reasonable? Explain.
Answers
Answer:
First you add all of the results together for a sum of 243. Then, you divide that sum, 243 by 10, the number of results in total. That means the average weight of 10 random raccoons out of 150 raccoons in that wildlife preserve, is 24.3 pounds. Her statement is not reasonable because Jean stated the average weight of ALL raccoons is 25 pounds.
Step-by-step explanation:
hope this helps :)
Step 1) 17+19+20+21+23+27+28+28+28+32=243
Step 2)
243 divided by 10 = 24.3pounds

Help ;/ 4.3 is 12.5% of what number?
Answers
Answer:
let x represent the number
12.5n/100=4.3
12.5n=4.3x100
12.5n=430
n= 430/12.5
n= 34.4
So...
X% times 4.3 equals 12.5
12.5 divided by 4.3 would give you 2.9069...
Now... it’s a percentage so multiply that by 100 and that would give you 290.69 or 290.7.

Answers
Answer:
65°
Step-by-step explanation:
We know that every triangle is equal to 180 degrees. Therefore, you have to subtract all angles by 180 to find what the missing angle is. The missing angle is 180-68-47. You can simplify this to 180-115. This is equal to 65. Therefore, the missing angle is 65 degrees.

The probability being fixed at 1/3, let's find which event in rolling a 6 sided dye will generate a probability of 1/3.
A- 6 sided number cube: with one roll (INCORRECT), however with a 3 sided number cube, P(0ne roll) = 1/3 (CORRECT)
B- A roll of an even number : P(even number) =3/6 =1/2 (INCORRECT), and a roll of an odd number P(odd number) = 3/6 = 1/2 (INCORRECT)
C- A roll of a number less than 3 , P(less than 3) =2/6 =1/3 CORRECT), whereas :a roll greater than or equal to 3. INCORRECT
D. A roll of a number that is not divisible by 3, P(not divisible by 3) = 4/6 =2/3 (INCORRECT): P( number number that is divisible by 3) =2/6 1/3 CORRECT
Can the numbers 24, 32, 40 be the lengths of the three sides of a right triangle? Explain why or why not. Write an essay. Pls, help. Thx
Answers
Answer:
Yes.
Step-by-step explanation:
Use the Pythagorean Theorem and Pythagorean triples.
One commonly used Pythagorean triple is 3, 4, 5.
24 is a multiple of 3 (3*8=24), 32 is a multiple of 4 (4*8=32), and 40 is a multiple of 5 (5*8=40). This concludes that the numbers 24, 32, and 40 can be the lengths of the three sides of a right triangle.
To further check our response, we can use the Pythagorean Theorem.
a^2+b^2=c^2
24^2+32^2=40^2
576+1024=1600
1600=1600

A suit originally costing $240 is on sale for 25% off the original price. Sales tax is 7.5%. What is the final cost of the suit?
A) 180
B) $193.50
C) $258
D) $166.50
Answers
Answer:
$193.50
Step-by-step explanation:
start by multiplying 240 by .25 (25%) to find out how much is 25% of 240. this equals 60.
then, subtract $60 from $240. equals 180.
next, to add the sales tax, multiply 180 by 0.075 (7.5%) this is $13.50.
lastly, add the tax, which is $13.50, to the suit's sale price, which is $180.
180+13.5= $193.50

Justin sells 78.5 ounces of lemonade for a total of $15.70.
Find the unit price in dollars per ounce.
If necessary, round your answer to the nearest cent.
Answers
The unit price doesn’t require any conversion(s) of values, so simply:
78.5 oz / $15.70 = 5 oz / $1
Reverse the proportion to find ‘dollars per ounce.
$0.20 per ounce
The unit rate of the lemonade is $0.2 per ounce.
What is unit rate?A unit rate means a rate for one of something.
Given that, Justin sells 78.5 ounces of lemonade for a total of $15.70.
We are asked to find the unit price in dollars per ounce.
Since, he sells 78.5 ounces in $15.70
So, in one ounce will be sold in = 15.70 /78.5 = 0.2
Hence, the unit rate of the lemonade is $0.2 per ounce.
