Answer:
Ratio [Model : Actual] = 1:16
Step-by-step explanation:
Given:
Height of model = [tex]2\frac{1}{2}[/tex] inches = 5/2 inches = 2.5 inches
Height of actual status = [tex]3\frac{1}{3}[/tex] feet = 10 / 3 feet
Find:
Ratio [Model : Actual]
Computation:
Height of actual status = [tex]3\frac{1}{3}[/tex] feet = 10 / 3 feet
Height of actual status = [10 / 3] x 12
Height of actual status = 40 inches
Ratio [Model : Actual] = 2.5 / 40
Ratio [Model : Actual] = 1:16

Which statements are true about a rectangular pyramid with a height of 9 centimeters and a base with the
dimensions of 4 centimeters by 6 centimeters? Select two options.
The area of the base of the pyramid, B, is 8 cm.
The area of the base of the pyramid, B, is 24 cm?
A rectangular prism with the dimensions of 9 cm by 4 cm by 6 cm will have 3 times the volume of this pyramid.
1
A rectangular prism with the dimensions of 9 cm by 4 cm by 6 cm will have 3 of the volume of this pyramid.
The volume of this pyramid is 216 cm
Answer:
- The area of the base of the pyramid, B, is 24 cm
- A rectangular prism with the dimensions of 9 cm by 4 cm by 6 cm will have 3 times volume of this pyramid.
Step-by-step explanation: Volume of a rectangular based pyramid = 1/3{Base area × Height}
Base Area = Length × Breadth
Volume = 1/3{(Length × Breadth) × Height}
Given a rectangular pyramid with a height of 9 centimeters and a base with the dimensions of 4
centimeters by 6 centimeters
Base Area = 4cm × 6cm
Base area = 24cm²
If Height =9cm
Volume of the pyramid = 1/3 × 24 × 9
Volume = 24 × 3
Volume of the pyramid = 72cm³
If the shape is a prism, the volume will be base area × height
= 24 × 9
= 216cm³
It can be seen that volume of rectangular prism = 3 × volume of rectangular pyramid.
What is the value of t in the following equation?
t + 14 = 2712
A. t = 37
B. t = 123
C. t = 213
D. t = 323
Answer: t = 2698 as question is written. Just subtract 14 from both sides. There is either a typo in the question or the answer choices.
Step-by-step explanation:
The functions f and g are defined as follows.
f(x)= 1/(x+2)
g(x)= square root of: (x-1)
(a)
State which value of x cannot be included in the domain of f.
(b)
Find the inverse of g(x)
(c) Calculate fg(10)
Answer:
x != -2, x^2 + 1, 1/5
Step-by-step explanation:
(a) It can be understood that nothing can divide 0
thus denominator cannot be 0 meaning x cannot be -2.
(-2 + 2) = 0
(b) y = sqrt(x-1)
inverse meaning we make x the subject
square both sides
y^2 = x - 1
y^2 + 1 = x
inverse = x^2 + 1
(c) composite function:
pass g(10) as domain of f
g(10) = 3, f(3) = 1/(5) = 1/5

The average value of a function f over the interval [−2,3] is −6 , and the average value of f over the interval [3,5] is 20. What is the average value of f over the interval [−2,5] ?
Answer:
The average value of [tex]f[/tex] over the interval [tex][-2,5][/tex] is [tex]\frac{10}{7}[/tex].
Step-by-step explanation:
Let suppose that function [tex]f[/tex] is continuous and integrable in the given intervals, by integral definition of average we have that:
[tex]\frac{1}{3-(-2)} \int\limits^{3}_{-2} {f(x)} \, dx = -6[/tex] (1)
[tex]\frac{1}{5-3} \int\limits^{5}_{3} {f(x)} \, dx = 20[/tex] (2)
By Fundamental Theorems of Calculus we expand both expressions:
[tex]\frac{F(3)-F(-2)}{3-(-2)} = -6[/tex]
[tex]F(3) - F(-2) = -30[/tex] (1b)
[tex]\frac{F(5)-F(3)}{5-3} = 20[/tex]
[tex]F(5) - F(3) = 40[/tex] (2b)
We obtain the average value of [tex]f[/tex] over the interval [tex][-2, 5][/tex] by algebraic handling:
[tex]F(5) - F(3) +[F(3)-F(-2)] = 40 + (-30)[/tex]
[tex]F(5) - F(-2) = 10[/tex]
[tex]\frac{F(5)-F(-2)}{5-(-2)} = \frac{10}{5-(-2)}[/tex]
[tex]\bar f = \frac{10}{7}[/tex]
The average value of [tex]f[/tex] over the interval [tex][-2,5][/tex] is [tex]\frac{10}{7}[/tex].

Solve 1= X^2+3x-16/X^2-6x+8
Answer:
x=1.816298 or x=−1.162524
Step-by-step explanation:
Step 1: Multiply both sides by x^2.
x2=x4−3x3+8x2−16
x2−(x4−3x3+8x2−16)=x4−3x3+8x2−16−(x4−3x3+8x2−16)(Subtract x^4-3x^3+8x^2-16 from both sides)
−x4+3x3−7x2+16=0
(Use quartic formula)
x=−1.162524,1.816298
Check answers. (Plug them in to make sure they work.)
x=1.816298(Works in original equation)
x=−1.162524(Works in original equation)

What is the slope of the line
A.1/2
B.1
C.-2
D.2
Here's a graph of a linear function. Write the equation that describes that function. 8 Express it in slope intercept form. Enter the correct answer.
Answer:
f(x) = [tex]\frac{1}{2}x+4[/tex]
Step-by-step explanation:
Let the equation of the function is,
f(x) = mx + b
Here, m = slope of the line
b = y-intercept
From the graph attached,
y-intercept 'b' = 4
Slope = [tex]\frac{\text{Rise}}{\text{Run}}[/tex]
= [tex]\frac{4}{8}[/tex]
= [tex]\frac{1}{2}[/tex]
Therefore, equation of the function representing the graph will be,
f(x) = [tex]\frac{1}{2}x+4[/tex]

The mass of a basket containing 3 balls was 3.64 kilograms. The mass of the same basket and 5 balls is 5.26 kilograms. Find the mass of the empty basket in kilograms.
Answer:
1.21 kilograms
Step-by-step explanation:
Let y represent the mass of the empty basket, and x represent the mass of each ball
Create a system of equations:
3x + y = 3.64
5x + y = 5.26
Solve by elimination by multiplying the top equation by -1
-3x - y = -3.64
5x + y = 5.26
Add them together, then solve for x:
2x = 1.62
x = 0.81
Plug this back into one of the equations and solve for y:
3x + y = 3.64
3(0.81) + y = 3.64
2.43 + y = 3.64
y = 1.21
So, the mass of the empty basket is 1.21 kilograms
Answer:
1.21 kilograms

ANSWER ASAP The questions on a multiple-choice test each have 5 answer choices.
Which of the following models could you use to simulate the
outcome of guessing the correct answer?
F. spinning a spinner with five equal sections
G. flipping a coin five times
H. spinning a spinner with four equal sections
I. rolling a number cube labeled one through six five times
Answer:
F, spinning a spinner with five equal sections
Step-by-step explanation:
The probability of something is (the ways to acheive the wanted outcome / all possible situations)
For example, the probability of getting heads on a coin flip is (1 possible way to get heads / 2 possible outcomes) = 1/2, or 50/50
Now, onto the problem.
There is only one way to get the answer right, and 5 possible situations. So, the probability of getting the question right would be 1/5.
F) Spinning a spinner with five parts means that you have: 1 way to get the right section, and 5 possible outcomes. So, the probability of getting the right section would be 1/5. So, this answer is correct.
G) Flipping a coin five times: Each time, you have a 1/2 chance of the coin landing on the desired side. So, this would not be an accurate comparison.
H) Spinning a spinner with four equal sections: There is one way to land on the desired section, and 4 possible outcomes. So, the probability of this simulation is 1/4, so this answer is incorrect.
I) Rolling a number cube labeled one through six times: Each time, there is one way to land on the number you want, while there are six possible outcomes. So, the probability of getting your desired number is 1/6, which is incorrect.
I hope this helps! Feel free to ask any questions!

Answer:
(a) The width is 40 inches
(b) It will not
Step-by-step explanation:
Given
[tex]D = 50[/tex] -- Diagonal
Solving (a): H = 30 --- (height).
Find the width (W)
To do this, we make use of Pythagoras theorem
[tex]D^2 = H^2 + W^2[/tex]
This gives:
[tex]50^2 = 30^2 + W^2[/tex]
[tex]2500 = 900 + W^2[/tex]
Collect Like Terms
[tex]W^2 = 2500 - 900[/tex]
[tex]W^2 = 1600[/tex]
Take square roots
[tex]W = 40[/tex]
Solving (b): Will it fit into a 30 in wide cabinet?
In (a) above, we calculated the width of the TV to be 40 inches
This implies that, the width is greater than the width of the cabinet.
So, it will not fit in
