Answer:
1.6875
Step-by-step explanation:
Volume of a pyramid = 1/3 (l*w*h)
Volume = 1/3(6 * 6 * 9)
Volume = 2 * 6 * 9
Volume = 108 cm³
Volume of cube = s³ ; s = side length
Volume = 4³ = 4 * 4 * 4 = 64 cm³
Number of wax cube = Volume of pyramid / volume of cube
= 108 cm³ / 64 cm³
= 1.6875

Calculate the area of each figure. Which figure has the greatest area?
Three figures. A parallelogram with height 7 centimeters and length 9 centimeters. A triangle with height 6.8 centimeters and base length 10 centimeters . A trapezoid with base lengths of 7 and 9 centimeters and a height of 3 centimeters .
parallelogram
triangle
trapezoid
Answer:
Triangle = 34
A = ½ (b × h)
Parallelogram = 63
A = b × h
Trapezoid = 24
A= (a+b)/2 x h
The one with the greatest area is Parallelogram (63)

Rhombus CDEF is shown below. If the slope
of FC is 5/2, what must be the slope of CD in order for CDEF to be a square?
Answer:
15
Step-by-step explanation:
trust
The slope of side CD in rhombus CDEF is -2/5. Therefore, option B is the correct answer.
What is a rhombus?A rhombus can be defined as a special parallelogram as it fulfills the requirements of a parallelogram, i.e. a quadrilateral with two pairs of parallel sides. In addition to this, a rhombus has all four sides equal just like a square. That is why it is also known as a tilted square.
Given that, the rhombus is CDEF and the slope of FC is 5/2.
Here, sides FC and CD are perpendicular.
The slope of a line perpendicular to given line is m₁=-1/m₂
Slope of CD is -2/5.
Therefore, option B is the correct answer.

The PRIDE club is selling school t-shirts and hoodies during football games. Two t-shirts and 2
hoodies will sell for $76.50. Five t-shirts and 3 hoodies will sell for $140.25. How much does
each shirt sell for?
Answer:
Cost of each hoodies = $25.5
Cost of each t-shirt = $12.75
Step-by-step explanation:
Given:
Cost of 2 t-shirt and 2 hoodies = $76.50
Cost of 5 t-shirt and 3 hoodies = $140.25
Find:
Cost of each t-shirt
Computation:
Assume;
Cost of each t-shirt = t
Cost of each hoodies = h
So,
2t + 2h = 76.50..........eq1
5t + 3h = 140.25..........eq2
Eq 1 x 2.5
5t + 5h = 191.25.............eq3
Eq3 - Eq2
2h = 51
h = 25.5
Cost of each hoodies = $25.5
2t + 2h = 76.50
2t + 2(25.5) = 76.50
t = 12.75
Cost of each t-shirt = $12.75

Neil Down is doing some remodeling and needs to cut a triangular piece of wood such that the diagonal is 10 feet long, and the sides of the triangle are in a ratio 3:4. How long should each side be?
Answer:
6 and 8
Step-by-step explanation:
Pythagorean theorem: a² + b² = c²
Given this,
(3x)² + (4x)² = 10²
9x² + 16x² = 100
25x² = 100
Divide both sides by 25
x² = 4
x = 2
Substitute this into 3x and 4x.
3x = 3 * 2 = 6
4x = 4 * 2 = 8
Thus, the answer is 6 and 8

State whether f^-1 (x) is a function given the equation
Answer:
We have that [tex]f(a) = f(b)[/tex] if [tex]a = \pm b[/tex], which does not respect the condition for the existence of an inverse function, which means that [tex]f^{-1}(x)[/tex] does not exist for this function.
Step-by-step explanation:
Existence of an inverse function:
An inverse function will exist if: f(a) = f(b) only if a = b.
In this question:
[tex]f(a) = -\frac{1}{7}\sqrt{16 - a^2}[/tex]
[tex]f(b) = -\frac{1}{7}\sqrt{16 - b^2}[/tex]
[tex]-\frac{1}{7}\sqrt{16 - a^2} =-\frac{1}{7}\sqrt{16 - b^2}[/tex]
[tex]\sqrt{16 - a^2} = \sqrt{16 - b^2}[/tex]
[tex](\sqrt{16 - a^2})^2 = (\sqrt{16 - b^2})^2[/tex]
[tex]16 - a^2 = 16 - b^2[/tex]
[tex]a^2 = b^2[/tex]
[tex]a = \pm b[/tex]
We have that [tex]f(a) = f(b)[/tex] if [tex]a = \pm b[/tex], which does not respect the condition for the existence of an inverse function, which means that [tex]f^{-1}(x)[/tex] does not exist for this function.
Which of the following is the correct point-slope equation for the line that passes through the point (2, -5) and is parallel to the line given by y = -4x + 25?
Answer:
(-4 - (-2))/(2 - (-2)) = -2/4 = -1/2
Step-by-step explanation:
Pick either point.
y - (-4) = (-1/2)(x - 2)
y + 4 = (-1/2)x + 1
y = (-1/2)x - 3

Volume can be measured by counting the number of unit cubic in a
three-dimensional figure.
what is Volume?The amount of space occupied by a three-dimensional figure as measured in cubic units.
Volume is the three- dimensional property, its basic units is always in cube.
Volume generally told us how much capacity can handle which we express it with the help of cubic units.
Volume doesn't wok on two dimensional bodies as well as the square is used for finding the area of the figure.
Thus, Volume can be measured by counting the number of unit cubic in a

An experiment was conducted to study the use of 95% ethanol versus 20% bleach as a disinfectant in removing contamination when culturing plant tissues. The experiment was repeated 15 times with each disinfectant, using cuttings of eggplant tissue. The observation reported was the number of uncontaminated eggplant cuttings after a 4-week storage.
Disinfectant 95% Ethanol 20% Bleach
Mean 3.74 4.86
Variance 2.78097 0.17142
n 15 15
Pooled variance 1.47620
1. Are you willing to assume that the underlying variances are equal?
a. Yes
b. No
2. Using the information from part (A), are you willing to conclude that there is a significant difference in the mean numbers of uncontaminated eggplants for the two disinfectants tested?
Answer:
a. Yes
Step-by-step explanation:
The term common variance means that each population has the same variance.
If σ²=σ₁²=σ₂² but unknown then the unbiased pooled or combined estimate of the common variance σ² is calculated.
In the given problem the pooled variance is calculated .
Therefore we assume that that the underlying variances are equal.
Using Student's t distribution
The given data is
Mean 3.74 4.86
Variance 2.78097 0.17142
n 15 15
Pooled variance 1.47620
t= x`1- x`2/ Sp √1/n1+ 1/n2
t = 3.74-4.86/ 1.47620 √1/15+ 1/15
t= -1.12/ 0.539
t= -2.0779
Taking the significance level ∝= 0.05 the
Value of the critical region is t≤ - t∝/2 and t≥ t∝/2 = ±2.048 for
Degrees of freedom = n1+n2- 2= 28
Hence the calculated value of t -2.0779 falls in the critical region therefore null hypothesis is rejected and and it is concluded that the means are not equal.
