A rectangular prism has a height of 15 centimeters and a width of 6 centimeters. The surface area of the prism is 684 square centimeters. What is the length of the prism?
A. 24 cm
B. 12 cm
C. 9 cm
D. 6 cm
Answer:
Step-by-step explanation:
Let the length be L
Formula
SA = 2Lw + 2Lh + 2wh
Givens
h = 15 cm
w = 6 cm
L = ?
SA = 684 cm^2
Solution
Substitue what you know into the given formula
2*6*L + 2*15*L + 2 * 6 * 15 = 684 Combine
12*L + 30*L + 180 = 684 Combine again
42L + 180 = 684 Subtract 180 from both sides.
42L +180 -180 = 684 - 180
42L = 504 Divide by 42
Answer: L = 12

Step-by-step explanation:
sine and cosecant : positive in Q1 and Q2
cosin and secant: positive in Q1 and Q4
tangent and cotangent: positive in Q1 and Q3.
Answer:
Quadrant I
Step-by-step explanation:
In the first quadrant all the 6 functions are positives.
Think instead of (x, y) any point has now the coordinate (cos α, sin α) so in quadrant I we have x, y positive therefore sin α and cos α are positive.
Tangent α is positive because is sinα/cosα = positive /positive = a positive
Cotangent α= 1/tan α = cosα / sinα = positive /positive = a positive
Secant α = 1/cos α = 1/ a positive number = a positive number
Cosecant α = 1/sin α = 1/ a positive number = a positive number

Write an equation in point-slope form for the graph shown below?
Answer:
y-4=-2/5(x+5)
Step-by-step explanation:
Points slip form is y-y₁=m(x-x₁)
Since you have a graph we can see the line goes down 2 and over 5. Since the slope is going downwards it is a negative slope. This mean m=-2/5. Then pick any point on the line ( I chose (-5,4)) and plug it in for y₁ and x₁.
A local Target store bought 90 pizzas at Pizza Hut for its holiday party. Each guest ate 1/6 of a pizza and there was no pizza left over. How many guests did Target have for the party?
By taking a quotient, we will see that the number of guests is 540.
How to find the number of guests?
Because we know that each guest ate a fixed amount of pizza, and there was no pizza left, we know that the number of guests will be equal to the quotient between the total number of pizzas bought, and the amount of pizza that each guest ate.
This is:
[tex]N = \frac{90}{1/6}[/tex]
We can rewrite that quotient as:
[tex]N = \frac{90}{1} / \frac{1}{6} = \frac{90*6}{1*1} = 540[/tex]
So the number of guests is 540.

Answer:
-5
Step-by-step explanation:
The range of values for x is {2, 26, 2.5, 5} in the given case where we have to enter values.
To provide a range of values for x based on the given information, we need to solve the equation 2x+10 = 14, 62, 15, and 20.
Let's solve the equation for each given value: 1. 2x+10 = 14:
Subtract 10 from both sides of the equation: 2x = 4
Divide both sides of the equation by 2: x = 2 2. 2x+10 = 62:
Subtract 10 from both sides of the equation: 2x = 52
Divide both sides of the equation by 2: x = 26 3. 2x+10 = 15:
Subtract 10 from both sides of the equation: 2x = 5
Divide both sides of the equation by 2: x = 2.5 4. 2x+10 = 20:
Subtract 10 from both sides of the equation: 2x = 10
Divide both sides of the equation by 2: x = 5
Therefore, the range of values for x is {2, 26, 2.5, 5}.

Students in a class were surveyed about the number of children in their families. the results of the survey are shown in the table. a 2-column table has 5 rows. the first column is labeled number of children in family with entries 1, 2, 3, 4, 5 or more. the second column is labeled number of surveys with entries 9, 18, 22, 8, 3. two surveys are chosen at random from the group of surveys. after the first survey is chosen, it is returned to the stack and can be chosen a second time. what is the probability that the first survey chosen indicates four children in the family and the second survey indicates one child in the family? startfraction 1 over 50 endfraction startfraction 2 over 15 endfraction startfraction 3 over 20 endfraction startfraction 17 over 60 endfraction
The probability that the first survey chosen indicates four children in the family, and the second survey indicates one child in the family is 1/5.
What is probability?The surveys are chosen with replacement (the first one is replaced before the second is chosen), and the events are independent.
This means that the probability of both together is the product of each event's probability.
The probability of choosing a survey that indicates 4 children in the family is 8/60 since there are 8 surveys with 4 children out of a total of (9+18+22+8+3) = 60 surveys.
The probability of choosing a survey that indicates 1 child is 9/60 since there are 9 surveys with 1 child out of a total of 60.
Together this gives us;
[tex]= \dfrac{8}{60} \times \dfrac{9}{60}\\\\ =\dfrac{ 72}{360} \\\\ =\dfrac{1}{5}[/tex]
Hence, the probability that the first survey chosen indicates four children in the family, and the second survey indicates one child in the family is 1/5.

The circumference of the base of the silo that the farmer plans to build to store chicken feed is 28.8 ft.
What is a cone and a circle?
A cone is simply a 3-dimensional geometric shape with a flat base and a curved surface pointed towards the top.
The volume of a cone is expressed as;
V = (1/3)πr²h
Where r is radius of the base, h is the height of the cone and π is constant pi ( π = 3.14 )
A circle is simply a closed 2-dimensional curved shape with no corners or edges.
The circumference of a circle is expressed mathematically as;
C = 2πr
Where r is radius and π is constant pi ( π = 3.14 )
Given the data in the question;
Volume of the cone ( silo ) V = 132ft³Height of the silo h = 6ftRadius r = ?We substitute our values into the expression above find the radius of the base of the silo.
V = (1/3)πr²h
132ft³ = (1/3) × 3.14 × r² × 6ft
132ft³ = 6.28ft × r²
r² = 132ft³ / 6.28ft
r² = 21.0191ft²
r = √21.0191ft²
r = 4.58ft
Now, since the radius of the base of the silo is 4.58ft, the circumference of the base will be;
C = 2πr
C = 2 × 3.14 × 4.58ft
C = 28.8ft
Therefore, the circumference of the base of the silo that the farmer plans to build to store chicken feed is 28.8 ft.

In a kickball game, a ball is kicked and travels along a parabolic path. The height h, in feet, of the kickball t seconds after the kick can be modeled by the equation h(t) = −16 t2 + 24t .
a. A fielder runs a route that will allow him to catch the kickball at about 3 ft above the ground. Write an equation that can be used to find when the fielder will catch the ball.
b. Use graphing technology to find out how long the kickball has been in the air when the fielder catches it on its descent. Round to the nearest hundredth.
The equation h(t) = -16t² + 24t is an illustration of a quadratic model
The equation when the fielder catches the ball is -16t² + 24t = 3The fielder will catch the ball after 0.14 seconds or 1.36 secondsThe equation when the fielder catches the ballThe equation that represents the path of the kick ball is given as
h(t) = -16t² + 24t
The fielder catches the ball at a height of 3 ft above the ground.
This means that:
h(t) = 3
So, we have:
-16t² + 24t = 3
Hence, the equation when the fielder catches the ball is -16t² + 24t = 3
How long the ball has been in the air whenIn (a), we have:
-16t² + 24t = 3
Rewrite as:
-16t² + 24t - 3 = 0
Next, we determine the solutions of -16t² + 24t - 3 = 0 using a graphing technology
From the graph (see attachment), we have the following solutions
t = 0.14 and t = 1.36
Hence, the fielder will catch the ball after 0.14 seconds or 1.36 seconds

A paper cup shaped like a cone has a diameter of 6 centimeters and a slant height of 7.5 centimeters. About how much paper is needed to make the cup
Answer:
22.5 cm^2
Step-by-step explanation:
Amount of paper is going to be measured in area, so we want the surface area of the cone. Since it is a cub it doesn't have a base, so we don't need to count it.
Area of the cone without the base, or what is called the lateral area is pi*r*s where r is the radius and s is the slant height. and of course radius is d/2 where d is the diameter. so let's plug it in. We know diameter is 6 and slant height is 7.5
SA = pi * r * s
SA = pi * d/2 * s
SA = pi * 6/2 * 7.5
SA = 22.5 cm^2
So you will need 22.5 square centimeters of paper.

Answer:
Mrs. Burgess will save $48 by buying a monthly pass.
Step-by-step explanation:
Let's compare the one-day pass to the monthly pass by finding how much 20 one-day passes will cost.
Multiply the price for a one day pass, $9.65, to the gym by 20 days:
$9.65 * 20 = $193Compare this price to the monthly pass price by subtracting these values.
$193 - $145 = $48If Mrs. Burgess buys the monthly pass of $145 instead of buying 20 day passes for $193, she will save $48.
