This figure shows an oblique triangle-based pyramid.
What is the volume of the figure?
Answer: 88 cm^3
Step-by-step explanation:
= 1/2 • bh
= 1/2 • 6 • 8
= 24
= 1/3 • 24 • 11
= 88 cm^3
The volume of the oblique triangle-based pyramid, having dimensions 6 cm, 8 cm, 11 cm, and 36.2 cm, is 88 cm³.
What is volume?The capacity occupied by a three-dimensional solid shape is known as volume. It is difficult to visualize in any shape, yet it may be compared among shapes. For instance, a compass box has a larger volume than an eraser placed inside of it.
Given:
The dimension of the pyramid are 6 cm, 8 cm, 11 cm, and 36.2 cm,
Calculate the volume as shown below,
The Volume of the pyramid = 1 / 3 × Area of the triangle × height
The volume of the pyramid = 1 / 3 × 1 / 2 × 6 × 8 × 11
The volume of the pyramid = 528 / 6
The volume of the pyramid = 88
Thus, the volume of the pyramid is 88 cm³.

How to complete the steps in order to write the inverse of f(x) = x + 5?The function is given as:
f(x) = x + 5
The opposite of the function f(x) = x + 5 is the inverse of the function.
So, we have:
f(x) = x + 5
Express f(x) as y
y = x + 5
Swap the positions of x and y

hello I'm stuck on this problem on my homework please help
Answer:
Given that mary deposits $93 each month in an annuity that pays 7.7% interest compounded montly.
To find the total value of the annuity in 28 years.
we have that,
The annuity formula helps in determining the values for annuity payment and annuity due based on the present value of an annuity due, effective interest rate, and several periods.
Formula for the annuity is,
\(FV=P×\frac{\left(\left(1+r\right)^n−1\right)}{r}\)where
P is the amount, n is the time period, r is the interest rate, FV is future value.
we get that,
P=93
\(r=\frac{7.7\%}{12}=0.641\%\)n=28x12=336
Substitute the values we get,
\(FV=93\times\frac{(1+\frac{0.641}{100})^{336}-1}{0.00641}\)Solving this we get,
\(FV=93\times\frac{(1.00641)^{336}-1}{0.00641}\)\(FV=93\times\frac{8.55817-1}{0.00641}\)\(FV=93\times\frac{7.55817}{0.00641}\)\(FV=93\times1179.1219\)\(FV=109658.339\)Round to nearest cent we get,

Suppose that 23 of work is needed to stretch a spring from its natural length of 30 cm to a length of 44 cm.
(a) How much work is needed to stretch the spring from 34 cm to 36 cm? (Round your answer to two decimal places.)
(b) How far beyond its natural lehgth will a force of 45 N keep the spring stretched? (Round your answer one decimal place.)
cm
Need Help
a) The work done is 3.3 J
b) The new force would stretch it 1.9 cm beyond its natural length.
What is Hooke's law?Hooke's law states that, the force of elasticity that tends to stretch a spring is directly proportional to the extension that is caused by the force as long as we do not by any means exceed the elastic limit of the material. This implies that the Hooke's law can only be found to hold when the elastic limit of the material has not been exceeded and the material has not become plastic.
Now;
F = Ke
W =1/2 Fe
F = 2W/e
W = work done
F = force exerted
e = extension
F = 2 * 23 /(44 - 30) * 10^-2
F = 328.6 N
a) To stretch 34 cm to 36 cm;
W = 1/2 * 328.6 N * 2 * 10^-2
W = 3.3 J
The work done is 3.3 J
b) F = Ke
328.6 N/(44 - 30) * 10^-2 = K
K = 2347 N/m
Then;
45 N = 2347 N/m * e
e = 45 N/ 2347 N/m
e = 0.019 m or 1.9 cm
New length = 30 cm + 1.9 cm = 31.9 cm
The new force would stretch it to a distance of 31.9 cm or 1.9 cm beyond its natural length.

\(\sqrt{12}=2\sqrt{3}\\\\\sqrt{18}=3\sqrt{2}\\\\\implies \sqrt{12} \sqrt{18}=2\sqrt{3}(3\sqrt{2}=\boxed{6\sqrt{6}}\)
The product of square root of 12 i.e.,√12 and square root of 18 i.e.,√18 is 6√6.
What is product law for exponent?When two numbers has equal power then we can multiply the the numbers and the power remains same. The number in the power is called exponent and the number is called as base. In \(a^m\), \(m\) is the exponent and \(a\) is the base of the number \(a^m\).
Step-by-step explanation:
\(\sqrt{12}\)\(=\sqrt{4}\)×\(\sqrt{3}\)\(=2\)×\(\sqrt{3}\) , since the square root of 4 is 2
\(\sqrt{18}=\sqrt{2}\)×\(\sqrt{9}\)\(=\sqrt{2}\)×\(3\) , since the square root of 9 is 3
Now, \(\sqrt{12} \sqrt{18} = 2\)×\(3\)×\(\sqrt{2}\)×\(\sqrt{3}\) from above.

\(\begin{gathered} \sin ^2\phi+\cos ^2\phi=1 \\ \cos ^2\phi=1-\sin ^2\phi \\ \cos ^2\phi=1-(-\frac{4}{5})^2 \\ \cos ^2\phi=1-\frac{16}{25} \\ \cos ^2\phi=\frac{9}{25} \\ \cos \phi=\pm\sqrt[]{\frac{9}{25}} \\ \cos \phi=\pm\frac{3}{5} \end{gathered}\)We, have two possibilities cos∅ is positive or cos∅ is negative.
By the first equation and the given information Tan∅ > 0, we know that
\(\frac{\sin \phi}{\cos \phi}>0\)Since sin∅ is negative, and sin∅/cos∅ is positive, cos∅ must be negative so tan∅ > 0. Then
\(\cos \phi=-\frac{3}{5}\)Using the second equation, we have that:

In the 2012 Olympics a U.S. athlete Nathan Adrian finished the 100-meter freestyle swim in 47.52 seconds. If nathan swam the same pace in a regular 25-meter pool what would his time have been per lap?
At the same rate as his 100-meter freestyle swim in the 2012 Olympics, Nathan Adrian could have completed one loop of a 25-meter pool in 11.88 seconds.
To solve this problem
The idea of proportionality can be applied. The time it would take Nathan Adrian to complete one lap in a 25-meter pool is known to be 47.52 seconds for the 100-meter freestyle. Since the tempo is constant while the distance varies, we can establish a ratio:
100 meters / 47.52 seconds = 25 meters / x seconds
where x is the unknown time for one lap in the 25-meter pool.
To solve for x, we can cross-multiply:
100 meters * x seconds = 47.52 seconds * 25 meters
100x = 1188
Dividing both sides by 100, we get:
x = 11.88 seconds
Therefore, at the same rate as his 100-meter freestyle swim in the 2012 Olympics, Nathan Adrian could have completed one loop of a 25-meter pool in 11.88 seconds.

What exactly is an angle?In Euclidean space, an angle is indeed a construction comprised of two beams that split at the apex & vertex, which are located in the middle of the angle. The side of loops are the name given to these rays. A combination of two rays may result in an angle that is within the planes in that they are located. Two planes can be combined to form an angle as well. They are referred to as dihedral angles. Two line rays with end points can be arranged in a variety of ways to create styles in two dimensions.

Based on equations, Angus worked 6 hours on Saturday and 10 hours at his after-school job last week earning a total of $127.80.
How the hours are determined:The hourly rate at Angus' Saturday job = $8.80
The hourly rate at Angus' after-school job = $7.50
The total earnings last week = $127.80
Let the hours Angus worked at Saturday job = x
Let the hours Angus worked after-school = 4 + x
The total hours worked = x + x + 4
2x + 4
Equations:The total earnings last week 127.80 = 8.8x + 7.5x + 4 (7.5)
127.80 = 8.8x + 7.5x + 30
127.8 - 30 = 16.3x
Hours worked at Saturday Job:x = 6 hours

B has a length of 7 yards and a width of 3 yards. The total volume of the solid figure is 180 cubic yards. What is the height of
rectangular prism B?
The height of rectangular prism B is 5 yards.
Let's first find the volume of rectangular prism B:
The volume of the solid figure = Volume of prism A + Volume of prism B
180 = 75 + length × width × height of prism B
105 = length × width × height of prism B
We know that the length of prism B is 7 yards and the width is 3 yards,
Substitute those values:
105 = 7 × 3 × height of prism B
105 = 21 × height of prism B
height of prism B = 105/21
