Answer:
Step-by-step explanation:
length = 120/8 = 15 feet
perimeter = (15 + 8) x 2 = 46 feet
The area is the product of the length and width then the length of the rectangle is 15 feet.
What is a rectangle?It is a polygon that has four sides. The sum of the internal angle is 360 degrees. In a rectangle, opposite sides are parallel and equal and each angle is 90 degrees. And its diagonals are also equal and intersect at the mid-point.
A rectangle has an area of 120 square feet and a width of 8 feet.
Then the length of the rectangle will be
Area = Length × Width
120 = 8L
L = 15
Then the length of the rectangle is 15 feet.

Answer:
(-∞, 2)Step-by-step explanation:
As we see on the graph, the range is:
(-∞, 2) ory < 2When Josh and Sean were each 5 years old, Josh was 1.5 inches taller than Sean. Josh grew at an average rate of 2.75 inches per year from the time that he was 5 years old until the time he was 13 years old. Josh was 63 inches tall when he was 13 years old. How tall was Sean when he was 5 years old?
A. 39.5 inches
B. 42.5 inches
C. 44.75 inches
D. 47.75 inches
Step-by-step explanation:
josh is 1.5 inches taller than sean
so, let sean's height be x
sean = x
josh = x + 1.5
each year josh gain 2.75 inches, and now he's 13 so how many year has passed
13 y - 5 y = 8
then how tall he grew
2.75×8=22
x + 1.5+22=63
x=63-22-1.5
x=39.5

What is exponential decay?An exponential function's curve is created by a pattern of data called exponential decay, which exhibits higher decreases over time.
The exponential decay function:
Aₙ = A₀(1-r)ˣ, where y = Final amount, A₀ = Initial amount, r = Rate of decay in decimal form, x = Time.
Given:
An element with mass 630 grams decays by 18.8% per minute.
That means, 18.8% = 0.188
Here, we will use the exponential decay function.
Aₙ = A₀(1-r)ˣ, where y = Final amount, A₀ = Initial amount, r = Rate of decay in decimal form, x = Time.
Here,
A₀ = 630 grams
r = 0.188
x = 7 minutes
Substituting the values to the formula,
A₇ = 630(1-0.188)⁷
A₇ = 630(0.812)⁷
A₇ = 630(0.23275134787)
A₇ = 146.633
A₇ = 146.6 grams.
Therefore, element is remaining 146.6 grams.

A gardener has a container with 6 3/5 ounces of liquid plant fertilizer. The gardener uses 2 1/2 ounces on a flower garden. How many ounces of liquid plant fertilizer are left? *
Answer:
4 1/10 ounces of Liquid plant fertilizer left
Step-by-step explanation:
Total quantity of Liquid plant fertilizer=6 3/5 ounces
Quantity used up on a flower garden=2 1/2 ounces
Quantity of liquid plant fertilizer are left=Total quantity of Liquid plant fertilizer -Quantity used up on a flower garden
6 3/5 ounces -2 1/2 ounces( subtract whole number from whole number and fraction from fraction)
6-2 3/5 - 1/2
4 (6-5) / 10
4 1/10 ounces of Liquid plant fertilizer left
Two shops, Lidal and Oldi, sell the same brand of toilet rolls but with different package sizes. Calculate the price per 36 rolls for each shop.
Answer:
The answer is below
Step-by-step explanation:
At Lidal shop, 4 toilet rolls is sold for £2.40. Therefore the cost of each toilet roll is given as:
Cost of each roll at Lidal = £2.40 / 4 = £0.60 per roll
Cost of 36 rolls = cost for each roll * 36 rolls = £0.60 per roll * 36 rolls = £21.6
At Oldi shop, 9 toilet rolls is sold for £4.68. Therefore the cost of each toilet roll is given as:
Cost of each roll at Oldi = £4.68 / 9 = £0.52 per roll
Cost of 36 rolls = cost for each roll * 36 rolls = £0.52 per roll * 36 rolls = £18.72
The crispy rice treats have cooled, Mrs. Williams cuts them into 30 equal pieces. She gives two-fifths of the treats to her son and takes the rest to school. How many treats will Mrs. Williams take to school?
Answer:
18 pieces
Step-by-step explanation:
divide 30 by 5
you'll get 6
so one-fifth is equivalent to 6 of the pieces
multiply 6 by 2
you'll have 2 so two-fifths is equal to 12 pieces of rice crispy treats
subtract 12 from 30
30 - 12 = 18
So she took 18 pieces to school.

Answer:
The amount of each ingredient Alicia uses to make oat biscuits are;
440 g of oat, 220 g of butter, and 110 g of syrup
Step-by-step explanation:
9. The question parameters are
The ingredients with which Alicia makes oat biscuit = Syrup, butter, and oat
The ratio of the ingredients with which Alicia makes oat biscuit = 1 : 2 : 4
The quantity of syrup Alicia has = Large amount (Plenty)
The amount of butter she has = 250 g
The amount of oat she has = 440 g
From the given ratio, we have;
The mass of oat Alicia uses is 2 times the mass of butter she uses and 4 times the mass of syrup she uses
When Alicia uses the 440 g of oat, we have;
The amount of butter she will use = 440 g/2 = 220 g
The amount of syrup she will use = 440 g/4 = 110 g
Therefore, Alicia uses the 440 g of oat, 220 g of butter, and 110 g of syrup

A floor 3.2m long and 2.8 m wide is to be covered with square shaped tiles of length 10cm. Find the coast of flooring if the coast tiles is Rs 150 per 100 tile.
Answer:
1344
Step-by-step explanation:
100cm = 1 m
Convert the dimensions of the floor to cm = Area of a rectangle = length x breadth = 320 x 280 = 89,600m²
Area of a square = length² = 10cm² = 100cm²
Number of tiles that would be needed = area of floor / area of square
89,600cm² / 100cm² = 896
Cost of one tile = rs 150 / 100 = 1.5
Cost of 896 tiles = 1.5 x 896 = 1344
