The volume of a pyramid can be given by the formula: V=31Ah. Where. A: Area of the V=(1/3)(B)(h)
multiply both sides by 3
3V=Bh
divide both sides by B
3V/B=h
Therefore, If it is wider it has more space to carry more items such as macaroni.
Lauren wants to gift wrap a box which is in the shape of a cube. The dimensions of the cube is 25 cm. Determine the surface area of the box to knov
how much wrapping paper should be purchased.
Answer:
3,750cm²
Step-by-step explanation:
Total surface area of a cube is expressed as;
A = 6L²
L is the side length of the cube;
Given
L = 25cm
TSA = 6 (25)²
TSA = 6 * 625
TSA = 3,750cm²
Hence the total surface area of the box is 3,750cm²
A rainstorm in Portland, Oregon, has wiped out the electricity in about 7% of the households in the city. A management team in Portland has a big meeting tomorrow, and all 6 members of the team are hard at work in their separate households, preparing their presentations. What is the probability that none of them has lost electricity in his/her household
Answer:
0.647 = 64.7% probability that none of them has lost electricity in his/her household
Step-by-step explanation:
For each household, there are only two possible outcomes. Either they lost electricity, or they did not. The probability of a household losing electricity is independent of any other household. This means that the binomial probability distribution is used to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
And p is the probability of X happening.
A rainstorm in Portland, Oregon, has wiped out the electricity in about 7% of the households in the city.
This means that [tex]p = 0.07[/tex]
6 members
This means that [tex]n = 6[/tex]
What is the probability that none of them has lost electricity in his/her household?
This is P(X = 0). So
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 0) = C_{6,0}.(0.07)^{0}.(0.93)^{6} = 0.647[/tex]
0.647 = 64.7% probability that none of them has lost electricity in his/her household
In the diagram below, O is circumscribed about quadrilateral ABCD. What is
the value of ?
Answer:
21
Step-by-step explanation:
Trust
The value of x is 21 because, in a quadrilateral, the sum of the opposite angles is equal to 180 degrees. option (A) is correct.
What is quadrilateral?
It is defined as the four-sided polygon in geometry having four edges and four corners and two pairs of congruent sides.
We have:
In the diagram below, O is circumscribed about quadrilateral ABCD.
In a quadrilateral, the sum of the opposite angles is equal to 180 degree
5x + 75 = 180
5x = 105
x = 21
Thus, the value of x is 21 because, in a quadrilateral, the sum of the opposite angles is equal to 180 degrees. option (A) is correct.

Answer:
v(t) = $342,000×1.06^tv(8) = $545,096v(15) = $819,623Step-by-step explanation:
When the growth (or decay) amount is a fraction or percentage of the current amount, an exponential model is indicated. Here, it will be of the form ...
value = (initial value) × (1 + (growth rate))^t
where t is the time period corresponding to the growth rate.
We are given that the initial value is $342,000 and the growth rate is 6% in a year. So, the model can be ...
value = 342,000×1.06^t . . . . . where t is years after 2017
__
In 2025, we are 8 years after 2017, so the value is predicted to be ...
value = $342,000×1.06^8 ≈ $545,096 . . . in 2025
__
In 2032, we are 15 years after 2017, so the value is predicted to be ...
value = $342,000×1.06^15 ≈ $819,623 . . . in 2032

The surface area of the square pyramid is, A. 80 in².
What is a pyramid?A three-dimensional figure is a pyramid. Its base is a flat polygon. The remaining faces are all triangles and are referred to as lateral faces.
The number of sides on its base is equal to the number of lateral faces. The line segments that two faces intersect to form its edges. The intersection of three or more edges forms a vertex.
The given figure is a pyramid having a square base.
The pyramid also has four triangular faces, each having a base of 5 in and a height of 8 in.
Therefore, the surface area of the pyramid is,
= 4[(1/2)×5×8] square inches.
= 80 in².

solve for the value of s
Answer:
s = 7 degrees
Step-by-step explanation:
All the angles have to add up to 180, so take 180 - 90 - 54 (the angles you know), and set them equal to 4s + 8. You get 36 = 4s + 8, subtract 8 from both sides, divide by 4, and you get that s = 7 degrees

America paid 3% interest on a $3900 car loan for 5 years. How much interest did she pay on her car loan?
Answer:
If America paid 3% interest for a year
At simple interset ,
FV = Pv(1 + it)
FV = Future value
Pv = present value
i = interest rate
t= time
FV = Pv(1 + it)
= $3900( 1+ 0.03 x 5)
= $4485
FV = PV + interest
FV - PV = interest
$4485 - $3900 = interest
interest = $585

Answer:
50+50x
Step-by-step explanation:
they're asking you to use distributive property
so what you have to do is multiply everything that is in the parenthesis by 10
5x10=50
5x10x=50x
so the answer is 50+50x
have a great day :D
========================================================
Explanation:
To get this answer, we multiply the outer term 10 by each term inside
5*10 = 505x*10 = 50xI'm using the distribution rule or distributive property. So that's why (5+5x)10 is the same as 50+50x
We could arrange the terms to get 50x+50 if you wanted.
--------------------------
Extra info (optional section):
Let's say that instead of 10, we had a smaller value like 2
(5+5x)2 would mean we have two copies of (5+5x) added together
So we'd have (5+5x)+(5+5x) = (5+5)+(5x+5x) = 10+10x
Then note how the distributive property says
(5+5x)*2 = 5*2+5x*2 = 10+10x
This is one example that helps us see how the distributive property is correct.
