What is the volume of this square pyramid?
Answer:
400m^3
Step-by-step explanation:
Answer: [tex]400m^{2}[/tex]
Step-by-step explanation:
In order to solve this square pyramid's volume, we use the formula:
V = 1/3(B)(h)
Now, we plug in what we know. Since it has a square base, the sides of the base are all the same:
1/3(10*10)(12)
Now we solve:
1/3(100)(12)
1/3(1200)

A water spout is filling a large container with water. After 5 hours the container held 24L of water. After 8 hours the container held 30L of water. At this rate, how much water was in the container at 2 hours?
Answer:
Step-by-step explanation:
This is a direct proportionality. If a water spout is filling a large container with water, hence the time taken to fill the container is directly proportional to the volume v of water. MAthematically;
t = kV
If after 5 hours the container held 24L of water, then;
5 = 24k
k = 5/24
Also if after 8 hours the container held 30L of water
8 = 30k
k = 8/30
To get the rate of the container at 2 hrs

Which statement is NOT an accurate comparison of the two dot plots?
A) There is a gap from 7 to 11 for Class A and there is no gap for Class B.
B) Class A is clustered around two areas, while Class B is clustered around the center. C) Class A spreads from 4 to 14, while Class B is spread from 3 to 9.
D) The median for both dot plots is 6.
Answer:
D
Step-by-step explanation:
The statement which is not an accurate comparison of the two dot plots is stated as: Option D) The median for both dot plots is 6
What are clusters in data?Clusters are groups in data. Each group is like clustered or grouped around some number, usually the mean of that cluster.
Spread, also called range of a data, tells the difference between the maximum and minimum value of that data, thus showing how much widely is it spread.
Thus, spread = maximum value - minimum value
For this case, we see that there are two clusters for class A and for class B there is only single cluster which is almost separated but not distinctly forming two clusters.
Class A spreads from minimum 4 to maximum 16, thus its spread is 16-4 = 12 units wide.
Class B spreads from minimum 3 to maximum 9, thus, its spread is 9-2 = 6 units wide.
Also, we can see that for class A, there is a gap from 7 to 11.
So all three options A, B and C are correct.
Now, let we find median.
Median is that value which is in mid of ordered (ascending or descending data set).
For class A, we have the data as:
4,4,4,4,4,5,5,5,6,6, 12,13,13,13,14,14
They are total 16 observations. The middle observation pair is 8th and 9th observation, which are 5 and 6
We can take any of the number between 5 and 6, so 5 < median < 6
That means median of class A's data is smaller than 6, thus, not being 6.
Thus, option D is incorrect and we don't need to find median of class B.
Thus, the statement which is not an accurate comparison of the two dot plots is stated as: Option D) The median for both dot plots is 6

Answer:
JK = 8
Step-by-step explanation:
Given 2 intersecting chords, then
The product of the measures of the parts of one chord is equal to the product of the measures of the other chord, that is
x(x + 4) = (x + 1)(x + 2) ← expand parenthesis
x² + 4x = x² + 3x + 2 ( subtract x² + 3x from both sides )
x = 2
Then
JK = x + 4 + x = 2x + 4 = 2(2) + 4 = 4 + 4 = 8
Brenya Estate produces a high quality tea branded A, B and C in the ration 1.5: 5: 1. Originally Type A tea costs 1600, type B costs 800 and type C costs 1700 per kg to produce. Brenya Tea Estate packs Super tea in packets of 825g each. Blending and packing costs are 40 per kg. Determine the production cost for a packet of super tea
Answer:
The production cost for a packet of super tea is 924.
Step-by-step explanation:
The production cost of the Super tea is given as
[tex]Cost_{super\ tea}=Cost_{A}+Cost_{B}+Cost_{C}+Cost_{packaging\ and\ blending}[/tex]
Here the costs are given as following
[tex]Cost_A=\dfrac{Ratio\ of\ A}{Sum\ of \ ratios} \times Weight \times Cost\ of\ A\ per\ kg[/tex]
Here
Ratio of A is 1.5Sum of Ratios is 1.5+5+1=7.5Weight is 825 g or 0.825kgCost of A per kg is 1600So
[tex]Cost_A=\dfrac{Ratio\ of\ A}{Sum\ of \ ratios} \times Weight \times Cost\ of\ A\ per\ kg\\Cost_A=\dfrac{1.5}{7.5} \times 0.825 \times 1600\\Cost_A=264[/tex]
The cost of A is 264.
Similarly
[tex]Cost_B=\dfrac{Ratio\ of\ B}{Sum\ of \ ratios} \times Weight \times Cost\ of\ B\ per\ kg[/tex]
Here
Ratio of B is 5Sum of Ratios is 7.5Weight is 825 g or 0.825kgCost of B per kg is 800[tex]Cost_B=\dfrac{Ratio\ of\ B}{Sum\ of \ ratios} \times Weight \times Cost\ of\ B\ per\ kg\\Cost_B=\dfrac{5}{7.5} \times 0.825 \times 800\\Cost_B=440[/tex]
The cost of B is 440.
Also
[tex]Cost_C=\dfrac{Ratio\ of\ C}{Sum\ of \ ratios} \times Weight \times Cost\ of\ C\ per\ kg[/tex]
Here
Ratio of C is 1Sum of Ratios is 7.5Weight is 825 g or 0.825kgCost of C per kg is 1700[tex]Cost_C=\dfrac{Ratio\ of\ C}{Sum\ of \ ratios} \times Weight \times Cost\ of\ C\ per\ kg\\Cost_C=\dfrac{1}{7.5} \times 0.825 \times 1700\\Cost_C=187[/tex]
The cost of C is 187.
Now the packaging and blending cost for the given package is calculated as
[tex]Cost_{packaging\ and\ blending}=Weight*Cost_{packaging\ and\ blending\ per\ kg}[/tex]
Here
Weight is 825 g or 0.825kgCost of packaging and blending per kg is 40[tex]Cost_{packaging\ and\ blending}=Weight*Cost_{packaging\ and\ blending\ per\ kg}\\Cost_{packaging\ and\ blending}=0.825*40\\Cost_{packaging\ and\ blending}=33[/tex]
Cost of packaging and blending per packet is 33.
So now substituting values of costs in the following equation gives:
[tex]Cost_{super\ tea}=Cost_{A}+Cost_{B}+Cost_{C}+Cost_{packaging\ and\ blending}\\Cost_{super\ tea}=264+440+187+33\\Cost_{super\ tea}=924[/tex]
The production cost for a packet of super tea is 924.

Answer:
6:5:4
Step-by-step explanation:
6 + 5 + 4 = 15
3000/15 = 200
200 x 6 = 1200 = eldest
200 x 5 = 1000 = 2nd eldest
1200 + 1000 = 2200
3000 - 2200 = 800
200 x 4 = 800 = youngest
Answer 6 : 5 : 4
Step-by-step explanation:
Its simply because
1200 ÷ 6 is 200 which is a whole number... If you divide for example 1200 by 7 it wont give you a whole... And also the first number of the ratio should be the greatest since the first child got the most money and the last the least which means the least should be the smallest number.

You plant a tree that is 36 inches tall. After one year, the tree is 43 inches tall. Which expression describes the percent of increase in the tree's height? 3643×100 43−3643 43−3636×100 43−3643×100
Answer:
19.4%
Step-by-step explanation:
Given data
Initial height=36in
Final height= 43in
% increase= Final-initial/initial*100
Substitute
% increase= 43-36/36*100
%increase= 7/36*100
%increase= 0.194*100
%increase= 19.4%
Hence the increase is 19.4%
