The area of a rectangle is 1,872 ft2. The ratio of the length to the width is 9:13. Find the perimeter of the rectangle. A. 88 ft B. 117 ft C. 168 ft D. 176 ft
Answer:
Length = 36
Width = 52
Step-by-step explanation:
Area of rectangle = Length * width
Length = L ; Width = W
Area (A) = 1872 ft²
Ratio L:W = 9:13
Hence,
1872 = lw - - - (1)
l/w = 9/13 - - - (2)
From (2)
13l = 9w
l = (9/13)w - - (3)
Put (3) into (1)
1872 = (9/13)w * w
1872 = 9/13 w²
24336 = 9w²
24336 / 9 = w²
2704 = w²
w = 52
If w = 52
1872 = 52 * l
l = 1872 / 52
l = 36
Length = 36
Width = 52
Andre types 208 words in 4 minutes. Noah typed 342 words in 6 minutes
A) Who typed faster
B) How many words can andre type in 10 minutes
C)Would you find the unit rate of words per minute or the unit rate of minutes per word to
figure out how long it would take Noah to write 1710 words? Why? (You do not need to
solve, just choose and explain why).
Answer:
Noah types faster because he can type more words per minute.
Step-by-step explanation:
For Andre you would divide 208 words by 4 minutes getting 52 words per minute. Then, for Noah divide 342 words by 6 minutes getting 57 words per minute.

Mr. Demers is making a drink by adding flavor drops to his water. If he puts 3 drops in a 12 ounce glass of water, how many ounces does he use PER DROP?
Answer:
Step-by-step explanation: if he puts 3 drops in a 12 ounce glass of water he should be using 4 ounces per drop 12 ounces divided by 3 drops gives you 4 ounces per drop
=======================================================
Explanation:
"Per drop" means "per 1 drop" or "for each 1 drop".
We start off with the ratio of
3 drops: 12 ounces
Divide both parts of that ratio by 3 so that "3 drops" turns into "1 drop"
Doing so gets us the new ratio of
1 drop: 4 ounces
So he uses 4 ounces per drop.

Sols the system 2x+y = 1 y = -2x^2+3x+1
Answer:y=(-2x+1) (x+1)
Step-by-step explanation:
2x+y=-2x^2 +3x+1
y=-2x^2+x+1
y=-2x^2 -2x+x+1
y=-2x(x+1) +1(x+1)
y=(-2x+1) (x+1)

Max is building a treehouse. He has a piece of wood that is 6 ft long. How many 1/3 ft pieces of wood can you cut
Answer:
18 pieces
Step-by-step explanation:
Max is building a treehouse. He has a piece of wood that is 6 ft long. How many 1/3 ft pieces of wood can you cut?
From the above question, we can deduce that:
1 piece of wood = 1/3ft
Hence:
1/3 = 1 piece of wood
6 ft = x
Cross Multiply
1/3ft × x = 6 ft × 1
x = 6 / 1/3
x = 6 × 3
x = 18 pieces
Hence, you can cut 18 (1/3 ft )pieces of wood .
Which of the following is equivalent to the image below
A: 6
B: 8
C: 12
D: 64
Answer: The answer is 8
Step-by-step explanation: first you solve 16 to the 1.5 power (3/2=1.5) and that gives you 64. Then 64 to the .5 power (1/2=.5) and that gives you 8.
The pendulum swings at an arc of 30 cm and its successive swings reduced to 10% of the previous swings. What is the total distance travelled by the pendulum after 5 swings? This problem is an example of what sequence?
Answer:
[tex]S_g= 33.333cm[/tex]
Step-by-step explanation:
From the question we are told that
Arc of 30 cm
10% reduction after each swing
Generally sum of geometric sequence is given by the equation
[tex]S_g=\frac{a(1-r^n)}{1-r}[/tex]
Mathematically solving for total distance traveled we have
[tex]S_g=\frac{30(1-(0.10^5)}{1-(0.10)}[/tex]
[tex]S_g=\frac{30}{0.9}[/tex]
Therefore the total distance traveled by the pendulum after 5 swings
[tex]S_g= 33.333cm[/tex]

Answer: m∠XYQ = 122°
Step-by-step explanation:
m∠XYQ + m∠QYZ = 180°
(10a + 2) + (5a - 2) = 180
15a = 180
a = 12
m∠XYQ = 10a + 2
m∠XYQ = 10 (12) + 2 = 122
m∠XYQ = 122°
A bicycle shop advertised all mountain bikes priced at a 1/3
discount. If the original price is $432, what is the sales
price?
Answer:
$288
Step-by-step explanation:
1/3 of a discount is = 2/3 of price
Multiply 432 by 2/3 and get 288.
Answer:
$288
Step-by-step explanation:
A 1/3 discount is .3333333... percent and so you simplify to .33 or 33% of a discount.
Multiply 432x.33 = 144
Subtract 432-144 to get 288 as you answer

Round to the nearest hundredth O(5x + 2) = 2(9x - 6) Type your answer...
Answer:
Solving the expression and round to the nearest hundredth
[tex]0(5x+2)=2(9x-6)[/tex] we get [tex]\mathbf{x=0.67}[/tex]
Step-by-step explanation:
We need to solve the expression and round to the nearest hundredth
[tex]0(5x+2)=2(9x-6)[/tex]
Solving:
[tex]0(5x+2)=2(9x-6)[/tex]
We know that multiplying anything by zero we get zero
[tex]0=2(9x-6)[/tex]
Switching sides
[tex]2(9x-6)=0[/tex]
Multiplying 2 with terms inside the bracket
[tex]18x-12=0[/tex]
Adding 12 on both sides
[tex]18x-12+12=0+12\\18x=12[/tex]
Divide both sides by 18
[tex]\frac{18x}{18}=\frac{12}{18}\\x=0.666[/tex]
Rounding to nearest hundredth we get:
[tex]x=0.67[/tex]
So, solving the expression and round to the nearest hundredth
[tex]0(5x+2)=2(9x-6)[/tex] we get [tex]\mathbf{x=0.67}[/tex]
