Problem 2
Check out the attached image below. I've subdivided the figure into various rectangles and triangles. The reason for this is because we'll then use the area formulas for rectangles and triangles. After finding the area of each little sub-region, you add them up to get the final answer.
We have these six regions: A, B, C, D, E, F
Regions B and D are squares, while everything else is a triangle
area of region A = base*height/2 = 1*3/2 = 1.5area of region B = base*height = 1*1 = 1area of region C = base*height/2 = 1*2/2 = 1area of region D = base*height = 1*1 = 1area of region E = base*height/2 = 1*2/2 = 1area of region F = base*height/2 = 1*3/2 = 1.5Add up those results:
1.5+1+1+1+1+1.5 = 7
Answer: 7 square units=============================================================
Problem 4
The figure is divided into various smaller pieces similar to the previous problem. There are probably a few different ways to subdivide.
This time nearly everything is a triangle, with the lone exception being region D which is a rectangle.
region A = base*height/2 = 1*2/2 = 1region B = base*height/2 = 1*2/2 = 1region C = base*height/2 = 2*1/2 = 1region D = base*height = 2*1 = 2region E = base*height/2 =1*1/2 = 0.5region F = base*height/2 = 3*1/2 = 1.5region G = base*height/2 =1*1/2 = 0.5Add up the subtotals
A+B+C+E+F+G = 1+1+1+2+0.5+1.5+0.5 = 7.5
Answer: 7.5 square units
Step-by-step explanation:
To make it easier, the figure is split by the lines.
Refer to picture
#2Parts 1 and 2 make 3 squaresParts 3 and 4 make 2 squaresPart 5 is 2 squaresTotal area:
3 + 2 + 2 = 7 square units#4Part 1 is 1.5 squaresParts 2, 3, 4 and 5 are half squares each, total 2 squaresParts 6 and 7 make 2 squaresPart 8 is 2 squaresTotal area:

A water sprinkler covers the area shown in the figure.
It moves through the covered area at a rate of about 5 per second.
What is the measure of the are covered by the sprinkler?
If the sprinkler starts at the far left position,
how long will it take for the sprinkler to reach
the far right position?
Answers
A water sprinkler has a rotational motion in order to reach a broad area
from its stationary location.
The time it takes the sprinkler to reach the far right position is 36 seconds.
Reasons:
The given parameter are;
The angular speed of the water sprinkler, ω = 5° per second
Location where the sprinkler starts = The far left position
Required:
The time it takes the sprinkler to reach the far right position.
Solution;
The angle covered by moving from the far left to the far right, θ = 180°
Time required is given as follows;
[tex]\omega = \mathbf{\dfrac{\theta}{t}}[/tex]
Therefore;
[tex]t = \dfrac{\theta}{\omega}[/tex]
Which gives;
[tex]t = \dfrac{180 ^{\circ}}{5^{\circ}/s} = 36 \, s[/tex]
The time it takes the sprinkler to reach the far right position, t = 36 seconds.

#14 A scale drawing of a rectangular room measures 2 cm by 4 and 1/4 cm. E
The scale used for the scale drawing is 1/2 cm = 5 ft. Carpeting will cost
$8.50 a square foot. How much will it cost to buy enough carpet to cover
the floor of this rectangular room? (**numbers and decimal only in answer
** NO $$ NO comma**) *
Answers
Answer:
Step-by-step explanation:
Width
1/2 cm = 5 feet
2cm = x Cross Multiply
1/2 x = 2 * 5 Combine
1/2 x = 10 Multiply both sides by 2
x = 20
Length
1/2 cm = 5 feet
4 1/4 cm = x Cross Multiply
1/2 x = 4 1/4 * 5 Combine the right
1/2 x = 21.25 Multiply both sides by 2
x = 42.5
Room Area
Area = 20 * 42.5
Area = 850 square feet
Cost
1 square foot costs 8.5 dollars.
850 square feet costs 8.5 * 850

A chemical company makes two brands of antifreeze. The first brand is 40% pure antifreeze, and the second brand is 60% pure antifreeze. In order to obtain 180 gallons of a mixture that contains 55% pure antifreeze, how many gallons of each brand of antifreeze must be used?
First brand =
Second Brand=
Answers
Answer:
Step-by-step explanation:
Let x be the portion of 60%
180 - x is the portion of 40%
0.60x + 0.40(180 - x) = 0.55(180)
0.60x + 72 - 0.40x = 99
0.20x = 27
x = 135
180 - 135 = 45
First brand = 45 gallons of 40%
Second Brand = 135 gallons of 60%

Answer:
0.07
Step-by-step explanation:
I'm sorry if its wrong
The probability that the hens lay a total of two eggs is 0.07. Therefore, the option B is the correct answer.
What is the probability?Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.
We know that, probability of an event = Number of favourable outcomes/Total number of outcomes.
Given that, Hannah has a chicken coop with six hens.
Let X represent the total number of eggs the hens lay on a random day.
Let the probability that the hens lay a total of two eggs be y
From the table,
X=0.02+0.03+y+0.12+0.30+0.28+0.18
We know that, the total of probability should be 1.
Now, 1=0.02+0.03+y+0.12+0.30+0.28+0.18
1=0.93+y
y=1-0.93
y=0.07
Therefore, the option B is the correct answer.

The answer (using BEDMAS) is 27
Step-by-step explanation:
The equation 9 x [(18+2) ÷ 5 - 1] is solved using BEDMAS or PEDMAS
First solve the smaller bracket
18 + 2 = 20
So then it becomes 9 x [20 ÷ 5 - 1]
Do the division inside the bracket next
20 ÷ 5 = 4
Then it becomes 9 x [4 - 1]
Do then subtraction within the bracket
4 - 1 = 3
Then it becomes 9 x 3
Finally solve 9 x 3 which equals 27

The perimeter of a rectangle is 94 yards. The width is 23yards less than the length. Find the length and the
width of the rectangle.
Answers
Answer:
The length = 35 ; The width = 12
Step-by-step explanation:
Perimeter = 2L + 2W
Length = x
Width = x - 23
94 = 2(x) + 2(x - 23)
94 = 2x + 2x - 46
94 = 4x - 46
94 + 46 = 4x
140 = 4x
140/4 = x
35 = x The length = 35; The width = (35 - 23) = 12
Perimeter = 2L+2W
Length = x
Width = x-23
94=2(x)+2(x-23)
94=2x+2x-46
94=4x-46
94+46
140=4x
140/4 4x/4

The members sold a total of 450 items. Of the items sold 2/3 were cupcakes and the remaining items were cookies. How much did the chess club members raise for the cookies that were sold?
A=150.00
B=85.00
C=75.00
D=450.00
Answers
Total amount raised for the cookies is $75, Option C is correct.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given that Cupcakes were sold for two dollars each.
Cookies were sold for $0.50 each.
The members sold a total of 450 items.
Let x be the number of cupcakes and y be number of cookies
x+y=450
Of the items sold 2/3 were cupcakes and the remaining items were cookies.
x = 2/3×450 = 300
Y= 450 - 300 = 150
The total amount raised from the cupcakes is $2× 300 = $600.
The total amount raised from the cookies is $0.50 × 150 = $75.
Hence, total amount raised for the cookies is $75, Option C is correct.
