The equation to find the total surface area of the cylinder is S = 2π(9)(h) + 2π(9)².
As per the question, the diameter of the cylinder is given as 18 inches, so we can calculate the radius (r) by dividing the diameter by 2:
r = 18 inches / 2 = 9 inches
The height of the cylinder is given as 4 inches.
To find the total surface area of a cylinder, we can use the following equation:
Total Surface Area = 2πrh + 2πr²
Now we can substitute the values into the equation to find the total surface area:
S = 2π(9)(h) + 2π(9)²
Therefore, the required equation is S = 2π(9)(h) + 2π(9)².

Find the volume of the figure.
Answer:
90 m³Step-by-step explanation:
Volume of the prism is the product of the base area and the height
Base area is:
A = 1/2*10*3.6 = 18 m²Volume is:
V = 18*5 = 90 m³Answer:
Required Answer :-The base is representing a trapezium.
So,
Area = ½ × 10 × 3.6
Area = 5 × 3.6
Area = 18 m²
Now,
Volume = 5 × Area
Volume = 5 × 18
Volume = 90 m²

Maria is in charge of making punch for the party she adds two quarts of water to 1 quart of orange juice and 2 quarts of mango juice then she adds one quart of crushed strawberry juice and 2 quarts of pineapple juice to the mixture how many quarts of punch does Maria make?
Answer:
8 quarts
Step-by-step explanation:
According to the scenario, computation of the given data are as follows,
Water = 2 quarts
Orange Juice = 1quarts
Mango Juice = 2 quarts
Strawberry juice = 1 quart
Pineapple Juice = 2 quarts
So, Total mixture = Sum of all ingredients in quarts
= 2 + 1 + 2 + 1 + 2 = 8 quarts
Hence, Maria makes 8 quarts of punch.

Answer:
12,300
Step-by-step explanation:
I'll right this as a function to make it easier on me.
f(x) = 7500(1 + 0.8)^x
f(2) = 7500(1 + 0.8)^2
f(2) = 7500(1 + 0.64)
f(2) = 7500(1.64)
f(2) = 12300
Answer:
$8700
Step-by-step explanation:
0.08 x 2 yrs = 0.16
7500 x 0.16 =1200
7500 + 1200 = 8700

Mr. D'Agostino decided he wanted to build a pool in his backyard this summer. He sketched a drawing that had a scale of 1 in. = 4 feet. If the drawing had a length of 4 feet and a width of 5 feet, what is the actual area of the pool?
Answer:
46080 ft²
Step-by-step explanation:
Given :
Scale :
1 in = 4 feets
Recall :
I foot =. 12 inches
Length of drawing = 4 feets
Length of drawing in inches = 4 * 12 = 48 inches
Width of drawing = 5 feets
Width of drawing in inches = 5 * 12 = 60 inches
Actual length of pool = 48 * 4 = 192 feets
Actual width of pool = 60 * 4 = 240 feets
The actual area of the pool :
Length * width
192 feets * 240 feets = 46080 ft²
What fact will help you to find the measure of angles B and C in the diagram shown?
A) An equilateral triangle has 3 congruent angles.
B)
The height of an isosceles triangle bisects the base.
C) The base angles of an isosceles triangle are congruent.
D)
The midsegment of an isosceles triangle is parallel to the base
Answer:
The Answer is C
Step-by-step explanation:
Look at B and C you can see that they have a line on each angle. Also, know that isosceles have two congruent sides. So when looking at this triangle we can infer that C is our best bet.

Answer:
1) False
2) True
3) a) True b) False
4) False
Step-by-step explanation:
1)
Two-point are collinear if they lie in the same line. The vector -2AB is antiparallel to the vector AB then it is False.
2)
A unit vector could be difinede as:
[tex]\vec{u}=\frac{\vec{v}}{|\vec{v}|}[/tex]
Terefore, [tex]\frac{1}{AB}\vec{AB}[/tex] is a unit vector. It is True.
3)
a) If AB=-3AC
The points, A, B, and C are collinear, because all of them lie in the same line. True
b) Let's take the modulus in each side.
[tex]\vec{AB}=-3\vec{AC}[/tex]
[tex]|\vec{AB}|=|-3\vec{AC}|[/tex]
[tex]|\vec{AB}|=|-3||\vec{AC}|[/tex]
[tex]|\vec{AB}|=3|\vec{AC}|[/tex]
So it is False.
4)
If we put the vector AI = 3/2 AB into the first equation we will have:
[tex]2(-\frac{3}{2}\vec{AB})+3\vec{IB}=-3\vec{AB}+3\vec{IB}[/tex]
And we can not say that it is a cero vector, so it is False.
I hope it helps you!
The point (-3, 2) lines on a circle whose equation is (x + 3)2 + ( + 1)2 = r2. Which of
the following must be the radius of the circle?
Answer:
3 units
Step-by-step explanation:
Equation of the circle is:
[tex] (x+3)^2 +(y+1)^2=r^2 [/tex]
[tex] \therefore [x-(-3)] ^2 +[(y-(-1)] ^2=r^2 [/tex]
Equating it with
[tex] (x-h)^2 +(y-k)^2=r^2 [/tex]
We find: h = - 3 & k = - 1
Center of the circle (C) = (-3, - 1)
Since, the point (-3, 2) lies on the circle, therefore radius of the circle wii be equal to the distance between the center of the circle (-3, - 1) and the point (-3, 2) which is on the circle.
Therefore,
[tex] r = \sqrt{[-3-(-3)]^2 +[2-(-1)]^2} [/tex]
[tex] r = \sqrt{[-3+3]^2 +[2+1]^2} [/tex]
[tex] r = \sqrt{[0]^2 +[3]^2} [/tex]
[tex] r = \sqrt{0 +9} [/tex]
[tex] r = \sqrt{9} [/tex]
[tex] r = 3\: units [/tex]
The area of a square photo frame is 144 cm2 . Find the perimeter of the photo fame, leaving your answer correct to 1 decimal place
Answer:
48 cm
Step-by-step explanation:
If it's square and the area is 144, then the sides are each 12cm (a = l x w, 144 = 12 x 12)
12cm x 4 sides = 48cm
Answer:
48
Step-by-step explanation:
The area is 144 cm².
A = s²
144 = s²
[tex]\sqrt{144\\}[/tex] = s
12 = s
photo frame is a square.
perimeter of a square = 4 * s
P = 4 *s
P = 4 (12)
P = 48

3x+4x = 10x - 45
7x = 10x - 45 transfer 45 to the other side of equation and subtract 7x from 10 10
45 = 10x - 7x
45 = 3x divide both sides by 3

ERROR ANALYSIS Describe the error in determining whether the lines are parallel, perpendicular, or neither.
Line 1: (3,-5),(2, -1)
Line 2: (0,3),(1,7)
There is a sign error in finding m
The slopes of perpendicular lines are negative reciprocals of each other.
Two lines are parallel when their slopes have the same absolute value.
In Line 2, one point is on the x-axis, so only the y-values should be subtracted to find the slope.

A trampoline was originally priced at $100 but went on sale for 60% off. If Emmett bought the trampoline and paid 5% sales tax, how much did he pay in total? $
Answer: $42
Step-by-step explanation:
Since the trampoline was originally priced at $100 but went on sale for 60%, the price paid will be:
= $100 - (60% × $100)
= $100 - (0.6 × $100)
= $100 - $60
= $40
Emmett bought the trampoline and then paid 5% sales tax, the total amount paid will be:
= $40 + (5% × $40)
= $40 + (0.05 × $40)
= $40 + $2.
= $42
She paid $42 in total.
Your pay rate is $20 per hour and you have a weekly pay period. You have worked overtime and accumulated 50 hours for the week. You get paid time and a half for overtime hours. Calculate your gross pay. *
Answer:
$1200 gross pay
Step-by-step explanation:
if you worked 40 hours normally and had 10 hours over time, that equation for the gross pay would be X = 20(40) + 30(10)
X = 20(40) + 30(10)
X = 800 + 300
X = 1200
Angle A and Angle B are supplementary angles. If angles A = 65, find the m Angle B.
Answer:
B = 115
Step-by-step explanation:
Since A and B are supplementary, they add up to 180 degrees.
Thus, 65 + B = 180, and B = 115
Stacy made 3 of her car payments late and was fined 3 late fees. The total change to her savings from late fees was - $24. How much was each late fee?
Answer:
$8
Step-by-step explanation:
I got my answer of $8 because I knew that the total amount of money she was charged for late fees was $24, and she was charged for 3 late fees. Then, I did $24 divided by 3 late fees and got $8 per late fee as my answer.
24 divided by 3 equals 8.

Step-by-step explanation:
hope this helps <3
Answer:
8 cards were in each pack

2. There are 35 men and 50 women running a race. What is the ratio of the number of female runners to the total number of runners? Answer:____________________________________
Answer:
10 : 17
Step-by-step explanation:
Male runners = 35
Female runners = 50
Total runners = male runners + female runners
= 35 + 50
= 85 runners
What is the ratio of the number of female runners to the total number of runners?
Ratio of the number of female runners to the total number of runners = number of female runners : total runners
= 50 : 85
= 50 / 85
= 10/17
= 10 : 17
Ratio of the number of female runners to the total number of runners = 10 : 17
