A window-washing crew can finish 15 windows in 18 minutes.
If this crew was assigned to wash all of the 24,348 windows on the outside of the Burj Khalifa at this rate, how long will the crew be washing at this rate?
Answer:
34321.2 min
Step-by-step explanation:
The Burj Khalifa has in total 28601 windows. On the other hand, we are told the window-washing crew can wash 15 windows in 18 minutes. So, we can use the Rule of three to solve this problem:
If:
15 windows ---- 18 min
28601 windows ---- ?
Then:
? = (28601windows)(18min)/15windows
? = 34321.2min
Answer:
34321.2 min

In March, Isaiah and Freddie had the same amount of money in their savings accounts. In April, Isaiah deposited $210 into his account. Freddie increased the money in his account by 15%. When they compared their balances, they found that they were still equal. How much money did they both have in their accounts in March? Enter your answer in your box
Answer:
Step-by-step explanation:
Answer:
Step-by-step explanation:
Let the original amount in Isaiah and Freddie's accounts be x
15%of x=$210
15x/100=$210
x=210*100/15
x=$1400
If y varies directly with x, and y = 2 when x = −4, what is the value of y when x = 20 ?
Answer:
y=kx
2=k.-4
k=-1/2
then
y=-1/2×20
y=-10
Answer:
y = - 10
Step-by-step explanation:
Given that y varies directly with x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 2 when x = - 4, that is
2 = - 4k ( divide both sides by - 4 )
[tex]\frac{2}{-4}[/tex] = k, that is
k = - [tex]\frac{1}{2}[/tex]
y = - [tex]\frac{1}{2}[/tex] x ← equation of variation
When x = 20, then
y = - [tex]\frac{1}{2}[/tex] × 20 = - 10
The area of a rectangle is 82.84 square meters. If the length is 7.6 meters, then what is the width?
hey i need help, anyone i don't get it do i divide or multiply HELPPPPP
Answer:
The answer is 10.9
Step-by-step explanation
#1 think of the formula of the area
length x width = area
#2 do the oposite of what you would to to find the area to find the width
82.84➗7.6 = 10.9
#3 check your answer
7.6 x 10.9 = 82.84
#3 answer
width= 10.9

=
x2y2−x3−y
x2
Step-by-step explanation:
Let's solve for b.
y=mx+b
Step 1: Flip the equation.
mx+b=y
Step 2: Add -mx to both sides.
mx+b+−mx=y+−mx
b=−mx+y
Answer:
b=−mx+y

Determine the coordinates of the point shown.
A coordinate grid shown. There are increments of 0.5 for each grid line on each of help will give brainliest .the two axes. A point is located at 3 grid lines to the right and 1 grid line down from the origin.
(1.5, −0.5)
(−0.5, 1.5)
(3, −1)
(1, −1)
x first so five to the left so it's negative and if each gridline is .5 and were are 5 gridlines aver then .5*5 so -2.5 then y is up so positive and 3 lines so .5*3 so 1.5 so coordinate is (-2.5,1.5)

If a sweatshirt cost $45, and sales tax is 7%, how much tax did you pay?
$48.15
Good Luck!!! :)
Answer:
Step 1: take the total price and divide it by one plus the tax rate.
Step 2: multiply the result from step one by the tax rate to get the dollars of tax.
Step 3: subtract the dollars of tax from step 2 from the total price.
Pre-Tax Price = TP – [(TP / (1 + r) x r]
TP = Total Price

16.1 – (–14.7) explain your work
Please help
Answer:
1.4 or 30.8
Step-by-step explanation:
1.4 is for regular math because it's basically 16.1 - 14.7
30.8 is for KCO or Keep Change Opposite (Beginners math)
Basically it would turn the equation into 16.1 + 14.7
You can use either but if you aren't sure ask your teacher about the strategy.
Hope this helps and if not tell me your strategy.
