Volume is a three-dimensional scalar quantity. The amount of sculpting material needed is 8 ft³.
What is volume?A volume is a scalar number that expresses the amount of three-dimensional space enclosed by a closed surface.
Since the pyramid is stacked one over the other, the total height of the sculpture is the sum of the four pyramid heights, therefore, the height of each pyramid is 1.5 ft.
The volume of the complete sculpture = 4(Volume of a single pyramid)
= 4[(1/3) × (2 ft)² × 1.5 ft]
= 4(2 ft³)
= 8 ft³
Hence, the amount of sculpting material needed is 8 ft³.

Use SOHCAHTOA to find the side measure. Show work. Round to one decimal place.
The value of the n is 64.04 after applying the tan ratio which is opposite to adjacent (TOA)
What is trigonometry?Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.
We have a right angle triangle shown in the picture.
We can use SOHCAHTOA to find the unknown length.
Using the ratio of tan which is opposite to adjacent (TOA)
tan8 = 9/n
n = 64.038 ≈ 64.04
Thus, the value of the n is 64.04 after applying the tan ratio which is opposite to adjacent (TOA)

Answer:
exponential growth
Step-by-step explanation:
f(x) = 4 * 2^x
This function is in the form
y = a * b^x where a is the initial value and b is the growth or decay rate
This is exponential form
if b > 1 then it is growth
0< b < 1 it is decay
b =2 so it is growth

The length of ribbon A is 56 feet and the length of ribbon B is 59 feet.
The exact length of ribbon C is 34 feet longer than the estimated difference in lengths of ribbon A and B.
What is the length of ribbon C?
Note - Use 0,12 or 1 as benchmarks.
The length of ribbon C is 37 feet.
What is the length of ribbon C?The equation that can be used to determine the length of ribbon C is:
C = 34 + ( length of ribbon B - length of ribbon A)
C = 34 + (59 - 56)
C = 34 + 3
c = 37 feet

One of the legs of a right triangle is twice as long as the other, and the perimeter of the triangle is 28. Find the length of the hypotenuse.
In a right triangle, the 58-cm hypotenuse makes a 51-degree angle with one of the legs. To the nearesttenth of a cm, how long is that leg?
Evaluate: sin (Arccos(5/13))
Evaluate: tan(Arctan(π/6))
1) If we let the lengths of the legs be x and 2x, then by the Pythagorean theorem,
[tex]x+2x+\sqrt{x^{2}+(2x)^{2}}=28\\3x+x\sqrt{5}=28\\x(3+\sqrt{5})=28\\x=\frac{28}{3+\sqrt{5}} \cdot \frac{3-\sqrt{5}}{3-\sqrt{5}}=21-7\sqrt{5}[/tex]
This means that the length of the hypotenuse is:
[tex]\sqrt{5}(21-7\sqrt{5})=\boxed{21\sqrt{5}-35}[/tex]
2) (Diagram attached) We know that
[tex]\cos 51^{\circ}=\frac{x}{58}\\x=58 \cos 51^{\circ} \approx \boxed{36.5}[/tex] (in cm)
3) From the Pythagorean identity,
[tex]\sin^{2}\left (\arccos \frac{5}{13} \right)+\cos^{2} \left (\arccos \frac{5}{13} \right)=1\\\left(\frac{5}{13} \right)^{2}+\sin^{2} \left (\arccos \frac{5}{13} \right)=1\\\frac{25}{169}+\sin^{2} \left (\arccos \frac{5}{13} \right)=1\\\sin^{2} \left (\arccos \frac{5}{13} \right)=\frac{144}{169}\\\sin \left (\arccos \frac{5}{13} \right)=\boxed{\frac{12}{13}}[/tex]

Previously, an organization reported that teenagers spent 4.5 hours per week, on average, on the phone. The organization thinks that, currently, the mean is higher. Fifteen randomly chosen teenagers were asked how many hours per week they spend on the phone. The sample mean was 4.75 hours with a sample standard deviation of 2.0. Conduct a hypothesis test.
The standard normal distribution is a special type of normal distribution where the mean is 0, and the standard deviation is 1. The hypothesis can not be concluded.
What is Standard normal distribution?The standard normal distribution is a special type of normal distribution where the mean is 0, and the standard deviation is 1.
For the given problems, the Hypothesis mean is 4.5. The sample mean was 4.75 hours with a normal standard deviation of 2.0.
Now, calculating the z-score,
[tex]z = \dfrac{\bar x - \mu_o}{\dfrac{\sigma}{\sqrt n}}\\\\\\z = \dfrac{4.75-4.5}{\dfrac{2}{\sqrt{15}}}\\\\\\z = 0.48[/tex]
Now, as per the standard normal table, the p-value is 0.6844. Since the p-value is greater than the significance level, the hypothesis can not be concluded.
Hence, The hypothesis can not be concluded.

How does the graph of y = a(x – h)^2 + k change if the value of h is doubled? The vertex of the graph moves to a point twice as far from the x-axis. The vertex of the graph moves to a point twice as far from the y-axis. The vertex of the graph moves to a point half as far from the x-axis. The vertex of the graph moves to a point half as far from the y-axis.
The vertex of the graph moves to a point twice as far from the y-axis.
Option B is the right answer.
What is the equation of Parabola ?The general equation of a parabola is
y = a(x-h)² + k
or
x = a(y-k)² +h
where (h,k) denotes the vertex.
It is given in the question that the value of h is doubled for the equation given
y = a(x-h)² + k
if the value of the h is doubled, the vertex of the graph shifts and shifts on the x axis away from the y axis , therefore
the vertex of the graph moves to a point twice as far from the y-axis.

if a quarter kilogram costs rs 60 then how much will cost for 150 grams
Answer:
R s. 36
Step-by-step explanation:
1kg ⇒ 1000g
So, a quarter kilogram means,
[tex]\frac{1}{4}[/tex] × 1kg = 1000g × [tex]\frac{1}{4}[/tex]
[tex]\frac{1}{4}[/tex] × 1kg = 250g
According to the question,
250g = R s. 60
So, now they're asking for the price of 150g.
Let that price be x.
250g ⇒ R s. 60
150g ⇒ x
Use cross multiplication to find the value of x.
250x = 60 × 150
250x = 9000
Divide both sides by 250.
x = R s. 36

8 more than twice Jenny's age
Use the variable j to represent Jenny's age. Please help.. :(
Answer:
2j + 8
Step-by-step explanation:
Given: 8 more than twice Jenny's age
Let j = Jenny's age
"twice Jenny's age" means double (multiply by 2) Jenny's age = 2j
"more than" means to add, so "8 more than" = + 8
Therefore:
"8 more than twice Jenny's age" = 2j + 8
