Answer:
9442 lb
Step-by-step explanation:
First find the volume of the tank. This being a sphere, the volume is V =(4/3)π·r³. Here the diameter is 17 ft, so the radius, r, is half that: 8.5 ft.
Then the volume of the sphere is V = (4/3)π·(8.5 ft)³, and half that (the volume of the hemisphere) is (2/3)π·72.25 ft³.
Water weighs 62.4 lb/ft³. To find the weight of the water in the full tank, multiply the tank volume by this weight density 62.4 lb/ft³:
×
(2/3)π·72.25 ft³ · 62.4 lb/ft³ ≈ 9442 lb
A shoe store donated a percent of every sale to charity. a the total sales were $9,800 so the store donated $588. What percent of $9,800 was donated to charity?
Answer:
They donated 6%.
Step-by-step explanation:
The total sales were $9800.
The amount donated is $588.
We want to know what percent of 9800 is 588.
Let's make an equation.
what percent of 9800 is 588
x/100 • 9800 = 588
Divide by 9800.
x/100 = 0.06
Multiply by 100.
x = 6
They donated 6%.
Hope this helps!
You answer 0.8 questions correctly.
a. What percent of the questions did you answer correctly?
you answer 0.8 questions correctly. what percent of the questions did you answer correctly. What fraction of the questions did you answer incorrectly? Use / for fraction and answer
Answer:
Step-by-step explanation:
Fraction:
0.8 = 8/10 = 4/5
Percent:
0.8*100 = 80%
Answer:
Solution :-0.8 can be written as
8/10 and
Percentage = 8/10 × 100
Percentage = 8 × 10
Percentage = 80%
Or,
Simply
Percentage = 0.8 × 100
Percentage = 80%

f ( x ) = 3 x 2 − 10 x − 9
what is 2x + 20 + 2x = 60
Answer:
= 1 0
Step-by-step explanation:
Solve
1. Combine like terms
2 + 2 0 + 2 = 6 0
4 + 2 0 = 6 0
2. Subtract 20 from both sides of the equation
4 + 2 0 = 6 0
4 + 2 0 − 2 0 = 6 0 − 2 0
3. Simplify
Subtract the numbers4 + 2 0 − 2 0 = 6 0 − 2 0
4 = 6 0 − 2 0
Subtract the numbers4 = 6 0 − 2 0
4 = 4 0
4. Divide both sides of the equation by the same term
4x = 40
4x/4 = 40/4
5. Simplify
Cancel terms that are in both the numerator and denominator4x/4 = 40/4
x = 40/4
Divide the numbersx = 40/4
x = 10

For the right triangles below, find the values of the side lengths d and a.
Round your answers to the nearest tenth.
Answer:
a = 1.4 and d = 6.9
Step-by-step explanation:
To get the value of d and a, we will use the SOH CAH TOA identity
For the first tringle;
Opposite = d ((opposite angle 60 degrees)
Adjacent = 4
Tan theta = opp/adj
Tan 60 = d/4
d = 4tan60
d = 4(1.732)
d = 6.9
For the second triangle;
Opposite = a
Hypotenuse = 2
Since sin theta = opp/hyp
Sin45 = a/2
a = 2sin45
a = 2(0.7071)
a = 1.4
Hence a = 1.4 and d = 6.9
The line y=2x+5 would pass through which of the following points?
A(0,2)
B. (0,10)
C. (0,5)
D. (0,7)
Answer:
C: (0, 5)
Step-by-step explanation:
The x-coordinates are all the same: 0. In y = 2x + 5, the 2x term would be zero in all those cases, leaving only the y-intercept (5).
We conclude that the line would pass through (0, 5), which is the y-intercept.

Answer:
188.24 (rounded)--- 188.2
Step-by-step explanation:
You want to first find the area of all the the different shapes you have...
you have 2 semicircles A= πr²/2 (because it is /2 you don't really need that because in the end you are going to *2 so just make the equation A= πr²)
you have a rectangle A= b*h
you have a triangle A = b*h/2
Semicircles: A= πr² = (3.14) 4² = (3.14*16) = 50.24
rectangle: A = b*h = 12*8 = 96
Triangle: A = b*h/2 = 12 * 7/2 = 84/2 = 42
then you add them up
50.24 + 96 + 42
= 188.24

The conditional relative frequency table below was generated by column using frequency table data comparing the number of calories in a meal to whether the meal was prepared at home or at a restaurant.
A 4-column table with 3 rows titled number of calories and location of meal preparation. The first column has no label with entries greater than or equal to 500 calories, less than 500 calories, total. The second column is labeled home with entries 0.15, 0.85,1.0. The third column is labeled restaurant with entries 0.55, 0.45, 1.0. The fourth column is labeled total with entries 0.28, 0.72, 1.0.
A nutritionist attempts to determine an association between where food is prepared and the number of calories the food contains. Which is most likely true?
An association cannot be determined because the value 0.55 is similar to the value 0.45.
There is an association because the value 0.15 is not similar to the value 0.55.
There is an association because the sum of each column is 1.0.
An association cannot be determined because the sum of the rows going across is not 1.0.
There is an association because the value 0.15 is not similar to the value 0.55
For the nutritionist to determine whether there is an association between where food is prepared and the number of calories the food contains, there must be an association between two categorical variables.
The conditions that satisfy whether there exists an association between conditional relative frequencies are:
1. When there is a bigger difference in the conditional relative frequencies, the stronger the association between the variables.
2. When the conditional relative frequencies are nearly equal for all categories, there may be no association between the variables.
For the given conditional relative frequency, we can see that there exists a significant difference between the columns of the table in the picture because 0.15 is significantly different from 0.55 and 0.85 is significantly different from 0.45
We can conclude that there is an association because the value 0.15 is not similar to the value 0.55

[tex] \boxed{(6, -3)} [/tex]
Step-by-step explanation:
Given the ratio 5:3
and Points A and B where A is located at (-6, 3), and B is located at (26, -13).
Let point A be [tex] (x_{1}, y_{1}) [/tex], and let point B be [tex] (x_{2}, y_{2}) [/tex].
(-6, 3) → [tex] (x_{1}, y_{1}) [/tex].
(26, -13) → [tex] (x_{2}, y_{2}) [/tex].
Let 5 be n, and 3 be m.
5:3 → n:m
[tex] (\frac{nx_{1} + mx_{2}}{n+m}, \frac{ny_{1} + my_{2}}{n + m}) [/tex].
To solve, just substitute these variables into the expressions of these coordinates to get the answer.
[tex] (\frac{nx_{1} + mx_{2}}{n+m}, \frac{ny_{1} + my_{2}}{n + m}) [/tex] →
[tex] (\frac{(5)x_{1} + (3)x_{2}}{(5)+(3)}, \frac{(5)y_{1} + (3)y_{2}}{(5) + (3)}) [/tex] →
[tex] (\frac{(5)(-6)+ (3)(26)}{(5)+(3)}, \frac{(5)(3)+ (3)(-13)}{(5) + (3)}) [/tex] →
