Answer:
16 m^3
Step-by-step explanation:
Question:
"a regular square pyramid is 3m height and the perimeter of its base is 16m find the volume of the pyramid"
volume of pyramid = (1/3) * (area of base) * height
The perimeter of the base is 16 m, and the base is a square.
perimeter of square = 4 * side
4 * side = 16 m
side = 4 m
area of square = (side)^2
area of base = (4 m)^2 = 16 m^2
volume of pyramid = (1/3) * (area of base) * height
volume = (1/3) * (16 m^2) * 3 m
volume = 16 m^2
a sandbox is in the shape of a right triangle. The two legs measure 9 inches and 16 inches. what is the perimeter of the sandbox?
Answer:
Perimeter = 50 inches
Step-by-step explanation:
Use pythagoreon theorem to find the hypotenuse
a^2 + b^2 = c^2
3^2 + 4^2 = 5^2
9 + 16 + 25 = perimeter
perimeter = 50

Evaluate 5.5r8.35s when r12 and s4.
Answer:
32.6
Step-by-step explanation:
when you plug in for s and r you will get 66-33.4 since 5.5 multiped by 12 is 66 and 8.35 multiplied by 4 is 33.4 .
then you subtract them and that's how you'll get your answer

If Z= 2+2i, what is z^4?
Answer:
D. 64 (cos(pi)+isin(pi))
Step-by-step explanation:
Put 2+2i into trigonometric form, raise the r value to the power of 4, and multiply the angle value (theta) by 4 to get the equation of z^4. In this case, r was 2(sqrt2), which raised to the 4th power was 64. The angle value was pi/4, which multiplied by 4 was pi. That's how we get the answer:
64 (cos(pi)+isin(pi)). How this helps!
Following are the calculation to the given value:
Given:
[tex]\to Z= 2+2i[/tex]
To find:
[tex]Z^4=?[/tex]
Solution:
[tex]\to Z= 2+2i[/tex]
[tex]\therefore\\\\i^2= -1[/tex]
[tex](a+b)^2= a^2+b^2+2ab[/tex]
Square the given value:
[tex]\to Z^2= (2+2i)^2[/tex]
[tex]= 2^2+(2i)^2+2 \times 2 \times 2i\\\\= 4+4i^2+8i\\\\= 4-4+8i\\\\=8i[/tex]
When [tex]Z^2= 8i[/tex] then again square the value
[tex]\to ( Z^2)^2= (8i)^2\\\\\to Z^4= 64i^2\\\\\to Z^4= -64\\\\[/tex]
Therefore, the final answer is "-64".

Bianca set the thermostat in her house to 87°F, which was 13° warmer than the temperature outside. What temperature was it outside?
Confused.
Answer: 74 degrees Fahrenheit
Step-by-step explanation: the temperature outside was 13 degrees lower than 87 degrees, so 87 - 13 = 74
Answer:
74 degrees F
Step-by-step explanation:
Subtract the 87 - 13
This is because there are +13 degrees more than outside. So if you add 74 + 13 that were added by the thermostat, you get 87 degrees. Does it make sense?
Just subtract :)

What is the domain of the function shown in this graph?
Domain is the set of x. Therefore, the domain starts from least x-value or from left side to the right side.
In the graph, it shows that the domain is from x = 1 to positive infinity.
Therefore the answer is x >= 1
or [1,+infinity) as interval.

Solve the system of equations using elimination.
3x-2y=5
x+2y=3
Answer:
x = 2
y = 1/2
Step-by-step explanation:
3x - 2y = 5
x + 2y = 3
We don't have to mutiply anything because we have values that we can eliminate.-2y and 2y can be crossed off becuase they have the same value and plus and minus cancel out. We can add instead of changing the signs.
4x = 8
x = 2
Now we know that x = 2. To find y we have to plug in x into one of the equations. I am going to use x + 2y = 3.
2 + 2y = 3
2y = 1
y = 1/2
Now we figured out y. I hope I helped!

Answer:
x = 5 22/24 OR x = 5 11/12
Step-by-step explanation:
x - 3/4 = 5 1/6
To solve this we mush use inverse operations
x - 3/4 + 3/4 = 5 1/6 + 3/4
x = 5 22/24
x = 5 11/12
To add the fractions there has to be a common denominator.
1/6 x 4/4 = 4/24
3/4 x 6/6 = 18/24
Keep denominators the same and add the numerators.
If your teacher wants the answer not simplified the answer is
x = 5 22/24
If your teacher wants it simplified the answer is
x = 5 11/12
I hope this helped and if it did I would appreciate it if you marked me Brainliest. Thank you and have a nice day!

A statistics teacher announces to the class at the beginning of the semester that there is a 40% chance that a randomly chosen student will finish the semester with an A in the class and there is a 60% that a randomly chosen student will get an A on a test during the semester. Is the probability that a randomly chosen student receives an A in the class and an A on a test during the semester equal to 0.24? Yes, because the chance of getting an A on a test and getting an A in the class are mutually exclusive.

Solve the system of linear equations by substitution.
1/2x +y=-4
y = 2x + 16
Answer:
y = 0
x = -8
Step-by-step explanation:
1/2x + y = - 4
y = 2x + 16
1/2x + (2x + 16) = - 4
1/2x + 2x = - 4 - 16
5/2x = -20
2/5 x 5/2x = -20 x 2/5
x = -40/5
x = -8
y = 2x + 16
y = 2(-8) + 16
y = -16 + 16
y = 0
Check:
1/2x + y = - 4
y = 2x + 16
1/2(-8) + (0) = -4
-4 + 0 = -4
-4 = -4
y = 2x + 16
(0) = 2(-8) + 16
0 = -16 + 16
0 = 0
