Answer:
Volume of this cylinder = 785.71 Cm³
Surface area of this cylinder = 157.14 Cm²
Step-by-step explanation:
Given:
Height of cylinder = 10 Cm
Radius of cylinder = 10 / 2 = 5 Cm
Find:
Volume of this cylinder.
Surface area of this cylinder
Computation:
Volume of this cylinder = πr²h
Volume of this cylinder = (22/7)(5)²(10)
Volume of this cylinder = 785.71 Cm³
Surface area of this cylinder = 2πr(h+r)
Surface area of this cylinder = 2(22/7)(5)(10+5)
Surface area of this cylinder = 2(22/7)(5)(15)
Surface area of this cylinder = 157.14 Cm²

If we transform y = x^2 by 5 units to the left and 8 units up, what is the vertex of the resulting parabola?
(-5, 8)
(5,8)
(-5, -8)
(5-8)
Answer:
(-5, 8)
Step-by-step explanation:
If the vertex of the parabola is on (0, 0), and moved to the left 5 units and up 8 units, the point would be (-5, 8). When a point is moved to the left, the number goes down, and when a point is moved up, it goes up in value. Therefore, you get (-5, 8).

Kathryn's school is selling tickets to a choral performance. On the first day of ticket sales the school sold 6 adult tickets and 11 student tickets for a total of $118. The school took in $156 on the second day by selling 12 adult tickets and 12 student tickets. What is the price of each adult ticket? What is the price of each student ticket?
Answer:
Adult price $5
Student price 8$
Step-by-step explanation:
Hello!
The school sells tickets for the choral performance with different prices depending on the ticket is for an adult or for a student of the school.
If X represents the price of an adult ticket and Y represent the price of a student ticket using the given information you can determine a set of two equations with two unknown values:
Day 1: 6 adult tickets and 11 student tickets for a total of $118
Symbolically: 6X + 11Y= $118
Day 2: 12 adult tickets and 12 student tickets for a total of $156
Symbolically: 12X + 12Y= $156
Step 1
From one of the formulas, clear one of the unknown values:
[tex]12X + 12Y= 156\\12Y= 156- 12X\\Y= \frac{156-12X}{12} \\Y= 13 - X[/tex]
Step 2
Replace the value obtained in step one in the second formula:
[tex]6X + 11Y= 118\\6X + 11(13 - X)= 118\\6X + (11*13) - 11X = 118\\6X -11X + 143= 118\\-5X= 118 - 143\\-5X= -25\\X= 5[/tex]
The ticket price for an adult is $5
Step 3
Using the value of X obtained in step 2, replace in the formula for Y to obtain the ticket price for students:
Y= 13 - X= 13 - 5= $8

Concrete can be purchased by the cubic yard. How much will it cost to pour a slab 17 feet by 17 feet by 2 inches for a patio if the concrete costs $40.00 per cubic yard? a. $76.45 b. $71.36 c. $90.67 d. $87.56
Answer:
The answer will be B ($71.36)
Step-by-step explanation:
17 ft. = 17/3 yd.
2 inch. = 2/(12 x 3) yd.
The cost will be: 40 x (17/3) x (17/3) x (2)(12/3) = 5780/81 = $71.358024...

Find the missing length idicated.
Answer:
x = 25.
Step-by-step explanation:
Since the longer side of the smallest triangle bisects the largest triangle's right angle, all three triangles shown are similar.
As seen in the diagram, the smaller triangle's hypotenuse (15) corresponds to the the largest triangle's hypotenuse (x), and the smaller triangle's shorter side length (9) corresponds to the largest triangle's shorter side length (15). So, we can set up a proportion...
[tex]\frac{x}{15} =\frac{15}{9}[/tex]
9 * x = 15 * 15
9x = 225
x = 225/9
x = 25

Yash brought apples and bananas to a picnic The number of apples was three more than twice the number of beane Tach brought 11 apples to the pionie. How many bananas dd he bring?
Answer:
25 bananas
Step-by-step explanation:
11 apples doubled is 22 then plus 3 in 25 this he brought 25 bananas
The number of bananas that Yash brought is 4 bananas.
It is given that Yash brought apples and bananas to a picnic. The number of apples was three more than twice the number of bananas.
We have to find out that how many bananas did he bring , if number of apple were 11.
What do you mean by linear equation in one variable ?
Linear equations in one variable is an equation which is expressed in the form of ax + b = 0, where a and b are integers and x is a variable.
As per the question ;
Tach brought 11 apples to picnic.
Let's assume the number of bananas = x
Number of apple = 11 = 2x + 3
⇒ 11 = 2 x + 3
⇒ 2x = 8
⇒ x = 8 ÷ 2
⇒ x = 4
Thus , the number of bananas that Yash brought is 4 bananas.

Which simplified fraction is equivalent of 5.6 3/15 14/25 5/6 14/250
Answer:
Thus, 28/5 is equivalent of 5.6
Step-by-step explanation:
Given
Number is 5.6
it is in decimal form.
The first number after decimal represent the tenth of number
The Second number after decimal represent the hundredth of number
and similarly we can define thousandth of a number.
Step to write decimal number in fractional form is (say a.bcd
write the full number without decimal
so number will be
abcd
divide the number by 1
abcd/1
now count the number of digit after decimal and put as many 0's after 1
there are three digits after decimal, we will put three digit after 1 in denominator
thus number in fraction is
abcd/1000
_________________________________________________
Given number is 5.6
hence writing it in fractional form as explained above
5.6 = 56/10
56 = 28*2
10 = 2*5
5.6 = 56/10 = 2*28/2*5 = 28/5
Thus, 28/5 is equivalent of 5.6
Find the domain of the rational function below. F(x)= (x-4)(x+2)/(x+3)(x-4)
Answer:
{x ≠ -3 ∪ x ± 4}
Step-by-step explanation:
The (x - 4) terms cancel, but x still may not = 4 (which would cause division by zero). Also, (x + 3) may not be zero (for the same reason), and so x ≠ -3.
The domain of this function is {x ≠ -3 ∪ x ± 4}
Filipe was playing with a triangle on a coordinate plane. The triangle's area is 24 square units. The largest circle he can fit in the triangle is centered at (0,0) and passes through the point (1.2,1.6). Approximately what percentage of the triangle does the circle cover?
Answer:
52.36%
Step-by-step explanation:
I did this problem on a test
52.33% is the percentage of the triangle does the circle cover.
What is Circle?A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre.
Area of triangle = 24 sq units
Center of Circle is at (0, 0) and the circle passes through (1.2, 1.6).
We need to find the percentage of triangle covered by circle.
we need to find the area of circle.
To find the area of circle, we need the radius of circle.
Radius of circle is the distance between the center of circle and any point that lies on the periphery of the circle.
Radius = =√(1.2-0)²+(1.6-0)²
=2 units
Now, area of circle is given by the formula:
Area = πr²=3.142×4=12.56 sq units
Percentage of Triangle covered:
Area of circle/Area of triangle × 100
12.56/24× 100
52.33%
Hence, 52.33% is the percentage of the triangle does the circle cover.

if one inch represents 14 feet how many inches would you use to make a scale drawing of a building that is 199 feet
Answer:
14.21 inches
Step-by-step explanation:
Given
1 inch = 14 feet
Required
Find the equivalent of 199 feet
Write out the given expression;
1 inch = 14 feet
Let x represent the equivalent of 199 feet in inches; Such that:
x = 199 feet
Write out both expressions
1 inch = 14 feet
x = 199 feet
Using cross multiplication; both expressions become
x * 14 feet = 199 feet * 1 inch
Divide both sides by 14 feet
[tex]\frac{x * 14 feet}{14 feet} = \frac{199 feet * 1 inch}{14 feet}[/tex]
[tex]\frac{x * 14}{14} = \frac{199* 1 inch}{14}[/tex]
[tex]\frac{14x}{14} = \frac{199* 1 inch}{14}[/tex]
[tex]x = \frac{199* 1 inch}{14}[/tex]
[tex]x = \frac{199inch}{14}[/tex]
[tex]x = 14.2142857143inch[/tex]

A special type of password consists of 3 different letters of the alphabet, and the two different numbers, where each letter and each number is used only once. How many different possible passwords are there?
Answer:
There can be 14,040,000 different passwords
Step-by-step explanation:
Number of permutations to order 3 letters and 2 numbers (total 5)
(AAANN, AANNA,AANAN,...)
= 5! / (3! 2!)
= 120 / (6*2)
= 10
For each permutation, the three distinct (English) letters can be arranged in
26!/(26-3)! = 26!/23! = 26*25*24 = 15600 ways
For each permutation, the two distinct digits can be arranged in
10!/(10-2)! = 10!/8! = 10*9 = 90 ways.
So the total number of distinct passwords is the product of all three permutations,
N = 10 * 15600 * 90 = 14,040,000
Which is the graph of the linear inequality 2x – 3y < 12?
B
Answer:
C.
Step-by-step explanation:
Given
2x - 3y < 12
Required
Find the graph it represents
we start by solving for the x and y intercepts;
Let x = 0
2x - 3y < 12 becomes
2(0) - 3y < 12
0 - 3y < 12
-3y < 12
Divide both sides by -3
-3y/3 < 12/-3
y > -4
Let y = 0
2x - 3y < 12 becomes
2x - 3(0) < 12
2x - 0 < 12
2x < 12
Divide both sides by 2
2x/2 < 12/2
x < 6
So, we have
x < 6 and y > -4
This implies that the graph is bound by the region where the values of x is less than 6 and the values of y is greater than -4
