Answer:
484 cm³
Step-by-step explanation:
The formula for the volume of a pyramid is ...
V = 1/3Bh
where B is the base area and h is the height.
Here, the base is a square 11 cm on a side, so its area is ...
B = s² = (11 cm)² = 121 cm²
Then the volume of the pyramid is ...
V = 1/3(121 cm²)(12 cm) = 484 cm³
Find the area of the figure below

Chris went out to dinner. His total bill before tax and tip was $23.40. He was charged an additional 8% tax and he also paid 15% tip on the original bill
Answer:
total cost = amount paid + tax paid + tip
total cost = $23.40 + 1.872 + $3.51
Step-by-step explanation:
Chris went out to dinner. His total bill before tax and tip was $23.40 He was charged an additional 8% tax and he also paid 15% tip on the original bill. Write an expression that will show the total cost including tax and tip.
total cost = amount paid + tax paid + tip
tax paid = 8% x $23.40
0.08 x $23.40 = $1.872
tip = 15% x original bill
0.15 x $23.40 = $3.51
total cost = $23.40 + 1.872 + $3.51
Solve the following question
Answer: It's C f"(x)= 15x^2+235 Hope that helps!
Step-by-step explanation:
Find the Greatest Common Factor (GCF).
GCF = 5
2. Factor out the GCF. (Write the GCF first. Then, in parentheses, divide each term by the GCF.)
5(15x^2/5+235/5)
3. Simplify each term in parentheses and that would give you 5(3x^2+47) and that's why I think it C but i'm not so sure but if you get it right can you please make me Brainliest bye and I hope you get it right!

If f(y) = 8 + e-9y, find f'(y). Use exact values.
Answer:
[tex]f'(y) = -9e^{-9y}[/tex]
Step-by-step explanation:
The given function is :
[tex]f(y) = 8 + e^{-9y}[/tex]
We need to find the value of f'(y).
[tex]f'(y)=\dfrac{d}{dy}[8+e^{-9y}][/tex]
[tex]=\dfrac{d}{dy}(8)+\dfrac{d}{dy}(e^{-9y})\\\\=0+e^{-9y}\dfrac{d}{dy}(-9y)\\\\=-9e^{-9y}[/tex]
So, the value of f'(y) is equal to [tex]-9e^{-9y}[/tex].

Answer:
3 or 1/3 depending on going from small to large, or from large to small
Step-by-step explanation:
the same scale factor applies to all sides of the transformed shape.
when going from small to large, every unit of side length turns into 3 units.
when going from large to small, every 3 units of side length turn into 1 unit.
The image shows a circle with center (4,6) and radius 10 units.

Create a BOX PLOT with this data set by using the Jamboard attached to this assignment... 3, 1, 3, 7, 5, 2, 3, 6, 3
Answer:
Step-by-step explanation:
in order to make a box plot you need to know 5 things.
the minimum, the first quartile, the median, the third quartile, and the maximum value. aka the five number summary
using your calculator you can find that in this set of values:
min = 1
Q1 = 2.5
med (Q2) = 3
Q3 = 5.5
max = 7
the box plot will look something like this:
If 4 daps = 7 yaps, and 5 yaps = 3 baps, how many daps equal 42 baps? **GIVING OUT BRAINLIEST**
Answer:
40 daps
Step-by-step explanation:
lets say daps is d, yaps are y and baps are b
4d = 7y, 5y=3b
First convert to y
4/7d = y
Now convert that to b
5(4d/7) = 3b
20d / 7 = 3b
20d / 21 = b
Plug it in:
42(20d/21)
40d
aka 40 daps

What is the size of the blue angle, and what do we call an angle with these measurements?
Answers:
The blue angle is 135 degrees
The angle is obtuse
==========================================
Explanation:
Along the inner ring of values, the left arrow points at 135 (the midpoint of 130 and 140). Therefore, the blue angle is 135 degrees. Or you could note that starting at 130, and counting 5 spaces, will get you to 135. You could start at 140, and count down 5 spaces to get to the same spot.
Another way you can get the answer is to note that the blue arrow on the left is pointing at 45 along the top ring of numbers. This adds to 90 to get 90+45 = 135
Either way, you should get to 135 degrees as the angle value.
-------------
The angle is obtuse because the angle is larger than 90 degrees. It's wider or larger than a right angle.
PLs, help me with this math question, and please answer if you only know it.
Answer:
Step-by-step explanation:
This is quite a doozy, so try and follow along. If you don't know your circle stuff well, it will be more difficult for you to understand how all this comes together.
First, we were given that angle CBD = 55. That means that angle CED is also 55 since they are both inscribed angles and they both intercept the same arc, arc CD. Angle BFC is congruent to angle 5 because they are vertical and vertical angles are congruent, so that means that triangle BFC is congruent to triangle EFD because of Angle-Angle-Side. Now that we got that out of the way, let's move on. We will come back to that in a bit.
Angle 1 intercepts arc BE and since angle 1 is an inscribed angle, it is half the measure of its intercepted arc. Therefore,
∠1 = 25° ; angle BCE also equals 25 degrees since they are both inscribed and they both intercept the same arc (again, arc BE).
If angle BCE is 25, and angle CBD is 55, then angle F, by the Triangle Angle Sum Theorem, must equal 180 - 25 - 55 = 100. And if Angle F = 100, then
∠5 = 100° . Angles 4 and 5 are supplementary, therefore,
∠4 = 80°
Since angle CBD was given as 55 and is an inscribed angle for arc CD, then arc CD is twice the measure of its inscribed angle and arc CD is 110 degrees. Angle 6, then, is one-half the difference of arc CD and arc BE so
∠6 = 30°
Angles 2 and 3 are congruent since they are both inscribed and they both intercept the same arc (arc DE); and since triangles BFC and EFD are congruent, by CPCTC, sides BF and EF are congruent...which means by the IsoscelesTriangle Theorem, angle 2 and angle BEC are congruent. 180 - 80 = 100 and divide that in half to get that
∠2 ≅ ∠3 = 50°
Lastly, angle 7 is half the measure of its intercepted arc (arc BE, given as 50), therefore,
∠7 = 25°
A wheel of radius 10 cm is turning at a rate of 5 revolutions per minute.
Calculate : the angle subtended at the centre by the minor arc.
Complete question:
A wheel of radius 10 cm is turning at a rate of 5 revolutions per minute.
Calculate the angle subtended at the centre by the minor arc after 1 second.
Answer:
the angle subtended at the centre by the minor arc is 30⁰
Step-by-step explanation:
Given;
radius of the wheel, r = 10 cm = 0.1 m
angular speed of the when, ω = 5 rev/min
duration of the motion, t = 1 second
Determine the angular speed in radian per second,
[tex]\omega = 5\ \frac{rev}{\min} \times \frac{2\pi \ rad}{1 \ rev} \ \times \frac{1 \min}{60 \ s} = \frac{10\pi \ rad}{60 \ s} = \frac{\pi }{6} rad/s[/tex]
After 1 second, the angular distance turned by the wheel is calculated as;
[tex]\theta = \omega t\\\\\theta = \frac{\pi \ rad} {6 \ s} \times 1 \ s\\\\\theta = \frac{\pi } {6 } \ rad\\\\in \ degrees; \theta = \frac{\pi \ rad}{6} \times \frac{180^0}{\pi \ rad} = \frac{180^0}{6} = 30^0[/tex]
Therefore, the angle subtended at the centre by the minor arc is 30⁰
