Calculate the perimeter
Answer:
48m
Step-by-step explanation:
12m - 4m = 8m / 2 = 4
12m + 4m + 4m + 4m + 4m + 8m + 8m + 4m = 48
the perimeter of rectangle is 2x² + 4x - 4y. its length is (2x - 3y). find the breadth of rectangle
plz help fast plz plz
Perimeter = 2 (l + b)
2x² + 4x - 4y = 2 {(2x - 3y) + b}
2x² + 4x - 4y = (4x - 6y) + 2b
2x² + 4x - 4y - (4x - 6y) = 2b
2x² + 4x - 4y - 4x + 6y = 2b
2x² + 2y = 2b
(2x² + 2y)/2 = b
x² + y = b
Breadth = x² + y

Find the median and mean number of hours for these students.
If necessary, round your answers to the nearest tenth.
Step-by-step explanation:
The mean (average) of a data set is found by adding all numbers in the data set and then dividing by the number of values in the set.
The median is the middle value when a data set is ordered from least to greatest.
If there is an even number of items in the data set, then the median is found by taking the mean (average) of the two middlemost numbers.
so, the mean value is
(10+10+18+18+10+5+12+13)/8 = 96/8 = 12
the median is first not clear when ordering the data set, as we have an even number of elements.
5 10 10 10 12 13 18 18
so, we have to take the mean or average between the 2 middle numbers : 10 and 12.
(10+12)/2 = 22/2 = 11
the median is 11.
A greengrocer bought 200 kg of oranges for $180 and sold them for $1.14 per kg. Find
a. His profit.
b. His percentage profit on the cost price.
Answer:
profit : $28
profit percentage: 14%
Step-by-step explanation:
his profit : $1.14 times 200kg = $228
228 -200 = 28
28 divided by 200 = 0.14
0.14 times 10 = 14 %
If you start off with 1220 and you take away 100 then add 50 how much do you have
1220 - 100 = 1120
1120 + 50 = 1170
Answer: 1170
Answer:
1170

A t-shirt increased in price by 1/4. After the increase, it was priced at £65. What was the original price of the t-shirt?
Answer:
52
Step-by-step explanation:
Given:
1/4
Price at 65
Solution:
Let x be the original price
Based on the given conditions, formulate: [tex]x[/tex] ×[tex](1+\frac{1}{4} )=65[/tex]
Apply Multiplicative Distribution Law: [tex]x+\frac{x}{4} =65[/tex]
Multiply both sides of the equation by the common denominator: [tex]x[/tex]×[tex]4+\frac{x X4}{4} =65 X 4[/tex]
Reduce the fraction: x×4+x=65×4
Multiply the monomials: 4x+x=65×4
Combine like terms: 5x= 65×4
Calculate the product or quotient: 5x= 260
Divide both sides of the equation by the coefficient of variable: x = [tex]\frac{260}{5}[/tex]
Calculate the product or quotient: x = 52
get the result: x = 52
Answer: x = 52

We have 5 ft 9 in = 69 in, so
P(X > 69) = P((X - 64.1)/2.5 > (69 - 64.1)/2.5) = P(Z > 1.96)
where X and Z both represent women's heights, but Z is normally distributed with mean 0 and s.d. 1.
Then consulting a table of z-scores, you'll find that P(Z > 1.96) ≈ 0.025. So approximately 2.5% of women are taker than 5'9''.

Kevin is twice as old as his sister Amy their father is five times as old as Amy if the sum of the ages is 64 how old is Amy
Answer:
8 years old
Step-by-step explanation:
Set Amy's age as x.
Kevin's age will be 2x, since he is two times as old as Amy.
Father's age will be 5x, since he is five times as old as Amy.
x + 2x + 5x = Sum of the ages = 64
x + 2x + 5x = 64
Combine like terms: 8x = 64.
Divide 8 on both sides: x = 8.
Amy's age = 8.
Hope this helps!
1428 rounded to the nearest thousandth
Answer:
1428- one is in the thousandth place
the number beside is lower than five so drop it and add zero to the end
1000 -is now your answer
Step-by-step explanation:
hope this helps if not then sorry goodluck and bye
The number 1428 to the nearest thousand is 1000.
When you round a number to a certain digit, you have to check the value of the digit before the place you want to round off to.
1. If the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up.
2. If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down.
Here, the question said the nearest thousand, so I had to look at the value in the hundred places which is 4 and less than 5.
Hence round the number down.
So, 1428 to the nearest thousand is 1000.

The price of a gallon of unleaded gas has dropped to 2.85 today. Yesterday's price was 2.91. Find the percentage decrease. Round your answer to the nearest tenth of a percent.
Answer:
2.85 divided by 2.91 is 0.97938144329
so about 97.9 percent 2.1 percent decrease
Answer:
2.1
Step-by-step explanation:
put change over original times percent over 100
so .06 times 100 is 6 and 6 divided by 2.91 is 2.06 and rounding to the nearest tenth would be 2.1%

7x(x-2y)
(2+1)(+5)
Step-by-step explanation:
7x(x - 2y)
= 7x.(x - 2y)
= 7x² - 14xy
= (2 + 1)(+5)
= (3)(5)
= 3 × 5
= 15
Step-by-step explanation:
1) 7x(x - 2y)
= (7x . x) - (7x . 2y)
= 7x² - 14xy
2) (2 + 1)(+5)
= 3(+5)
= (3 . +5)
= (3 . 5)
= 15
