An easy way to find the surface area of a composite figure is to divide the composite figure up into smaller shapes whose area it is easier to find. It is best to divide a composite figure up into a figure composed of many triangles and rectangles. Then, one will find the area of each of these smaller figures and add the value up to find the total surface area of the composite figure.

Question is ;
Complete question is;
Boston , Massachusetts, and buffalo, New York, are hit by snowstorms that last 3 days . Boston accumulates snow at a rate of 1.5 feet every 36 hours. Buffalo accumulates snow at a rate of 0.01 inches every minute.
Which city accumulates more snow in 3 days? How much more snow?
Answer:
- Boston accumulates more snow in 3 days.
- It accumulates 0.6 ft of snow more than Boston
Step-by-step explanation:
Boston accumulates 1.5 feet of snow every 36 hours.
Number of hours in 3 days = 24 × 3 = 72 hours.
Thus, In 72 hours, Boston would have accumulated; (1.5 × 72)/36 = 3 feet of snow.
Now, Buffalo accumulates 0.01 inches of snow every minute.
In 3 days, number of minutes we have = 60 × 24 × 3 = 4320 minutes
Thus, total snow accumulated in 3 days = 0.01 × 4320/1 = 43.2 inches
Now, let's convert this to ft;
12 inches = 1ft
Thus; 43.2 inches = 43.2 × 1/12 = 3.6ft
Thus, Buffalo accumulates more snow in 3 days.
It accumulates 0.6 ft of snow more than Boston
(x+5)(x+1)+(x+5)(x+8)
Answer:
2x² + 19x + 45
Step-by-step explanation:
(x + 5)(x + 1) + (x + 5)(x + 8) ← expand both sets of factors using FOIL
= x² + 6x + 5 + x² + 13x + 40 ← collect like terms
= 2x² + 19x + 45

Step-by-step explanation:
We have to multiply 9 for itself for 6 times
4x+3y=1 2x+5y=11 solve for x and y
4x+3y=1 2x+5y=11
We'll need to use system of equations for this one.
4x+3y=1
3y=1-4x
y=-4/3x+1/3
2x+5y=1
5y=1-2x
y=-2x/5+1/5
Set these two equations equal to each other and solve for x.
-2x/5+1/5=-4/3x+1/3
x=1/7
Then plug x in to solve for y.
y=-2(1/7)/5+1/5
y=1/7

What is the length of Hypotenuse?
A. [tex] \sf \sqrt{40\: ft} [/tex]
B. [tex] \sf\sqrt{96\: ft} [/tex]
C. [tex] \sf\sqrt{208\: ft} [/tex]
D. [tex]\sf 20 \: ft[/tex]
E. [tex]\sf 48 \: ft[/tex]
____________________Solution :-Given Information :- Base of Triangle = 12 ftBase² = 12² = 144 ftAltitude of Triangle = 8 ftAltitude² = 8² = 64 ftTo Find :- Hypotenuse of Triangle Formula Used :- Pythagoras Theorem ↓Hypotenuse² = Base² + Altitude²Calculation :-Here, we will substitute the given values in the formula,
⇒ Hypotenuse² = ( 144 + 64 ) ft
⇒ Hypotenuse² = 208 ft
Now transposing the square to Right Hand Side, We get,
⇒ Hypotenuse = [tex] \sf \sqrt{208} \: ft[/tex]
∴ Hypotenuse = [tex] \sf \sqrt{208} \: ft[/tex]
____________________Final Answer :-The Hypotenuse of Right Triangle is [tex] \sf \sqrt{208} \: ft[/tex]
Hence, Option C. [tex] \bf \sqrt{208} \: ft[/tex] is correct answer.
____________________Lorenzo needs to run 13 1/2 miles this week to meet his goal of his first training plan so far this week he has ran 3 1/2 Miles on Monday and 4 1/4 miles on Tuesday how many more miles does he need to run this week in order to meet his goal
Answer:
5 3/4 hours remaining to meet his goal
Step-by-step explanation:
miles required to meet his goal = 13 1/2 miles
Miles ran on monday =3 1/2
Miles ran on Tuesday =4 1/4
Miles remaining to reach his goal =Total miles required - Miles ran on Monday and Tuesday
13 1/2 - ( 31/2 + 4 1/4 )
131/2 - 7 3/4
change to improper fraction for easy solving
27/2 -31/4
54-31 /4=23/4 =5 3/4 hours
what is the area of the figure below
Answer:
Option A
Step-by-step explanation:
Area of the composite figure = Area of ΔABH + Area of BCGH + Area of ΔDEF
Area of ΔABH = [tex]\frac{1}{2}(\text{Base})(\text{Height})[/tex]
= [tex]\frac{1}{2}(6)(8-5)[/tex]
= 9 in²
Area of the trapezoid = [tex]\frac{1}{2}(CG+BH)(\text{Distance between these lines})[/tex]
= [tex]\frac{1}{2}(6+4)(5)[/tex]
= 25 in²
Area of ΔDEF = [tex]\frac{1}{2}(8)(6)[/tex]
= 24 in²
Therefore, area of the given figure = 9 + 25 + 24
= 58 in²
Option A will be the correct option.

Daija is looking to fertilize her 24,000 square foot lawn. Super Lawn fertilizer costs $18.49 and covers 6,000 square feet. Quick Fertilizer costs $23.99 and covers 8,000 square feet.
Answer:
A.) Cheaper Fertilizer is Quick Fertilizer
B.) The cheaper fertilizer now cost $ 61
Step-by-step explanation:
The exact question is as follows :
Given - Daija is looking to fertilize her 24,000 square foot lawn. Super Lawn fertilizer costs $18.49 and covers 6,000 square feet. Quick Fertilizer costs $23.99 and covers 8,000 square feet.
To find - A.) Which fertilizer would be cheaper for Daija to purchase to fertilize her entire lawn?-Show your work or explain your answer.
B.) Daija has a 15% off coupon on the cheaper fertilizer. Excluding sales tax, what is the new cost of the fertilizer? Round to the nearest cent.
Proof -
A.)
Given that,
Total lawn that have to be fertilize = 24,000
Now,
Super Lawn fertilizer costs $18.49 and covers 6,000 square feet.
i.e.
6000 square feet = $ 18.49
⇒4×6000 square feet = $ 4×18.49
⇒24000 square feet = $ 73.96
∴ we get
Super Lawn costs $ 73.96
Now,
Quick Fertilizer costs $23.99 and covers 8,000 square feet.
i.e.
8000 square feet = $ 23.99
⇒3×8000 square feet = $ 3×23.99
⇒24000 square feet = $ 71.97
∴ we get
Quick Fertilizer costs $ 71.97
As we get
Super Lawn costs $ 73.96
Quick Fertilizer costs $ 71.97
As $ 71.97 < $ 73.96
So,
Cheaper Fertilizer is Quick Fertilizer
B.)
As we get from part a) that
Quick Fertilizer is cheaper and it costs $ 71.97
So,
15% of 71.97 = 10.7955
∴ we get
Now,
Quick fertilizer cost = $ 71.97 - 10.7955
= $ 61.1745 ≈ $ 61
So,
After applying the 15% coupon,
The cheaper fertilizer now cost $ 61

Resuelve el siguiente problema de fracciones y escoge la alternativa correcta: Jaime compra una propiedad en 84000 dólares y después de un año la vende ganando los 1/4 del precio de compra. ¿Cuánto fue la ganancia? *
Answer:
$21,000
Step-by-step explanation:
Solve the following fraction problem and choose the correct alternative: Jaime buys a property for $ 84,000 and after one year sells it earning 1/4 of the purchase price. How much was the profit? *
The amount of profit is calculated as
1/4 of the purchase price
Purchase price = $84,000
= 1/4 of $84,000
= 1/4 × $84,000
= $21,000
Therefore, the amount of the profit = $21,000

Step-by-step explanation:
the graph shown is not a function because points (-1,2) and (fill in the blank) have the same x value
For a graphed line to be a function it needs to pass the vertical line test.
If a vertical line goes through the graphed line in more than one x axis then it is not a function.
Using the given point (-1,2) drawing a vertical line at X = -1, you can see the other vertical line goes through the graphed line at point (-1,0)
Answer: (-1,0)
