Answer:
904.32 cubic ft
Step-by-step explanation:
To find the volume of a sphere, the formula is [tex]4\pi\frac{r^3}{3}[/tex]
First, 3.14 * 4 for 12.56.
The radius is 6, and that cubed is 216.
After that, divide 216 by 3 for 72
Then, 12.56 times 72, which gets you the final answer of 904.32 cubic ft.
(10 * 72) + (2 * 72) + (0.5 * 72) + (0.06 * 72)
720 + 144 = 864
864 + 36 = 900
900 + 4.32 = 904.32

What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
y = 4x be equation (1)
On simplifying the equation , we get
when x = 1
y = 4 ( 1 )
y = 4
when x = 2
y = 4 ( 2 )
y = 8
when x = 3
y = 4 ( 3 )
y = 12
when x = 4
y = 4 ( 4 )
y = 16
Therefore , the values of y are { 4 , 8 , 12 , 16 }

Step-by-step explanation:
1. One factor is a two digit number between 1 and 10 2. One factor is a two digit number between 1 and 10 ( different from the first) 3. The product is greater than 8. But less than 10
Answer: 3.5 * 2.5 = 8.75
Step-by-step explanation:
The factors are to be less than 10 but are should be two digit numbers. The only way this is possible would be if they had decimals.
Which two numbers below 10 can give a product less than 10 but more than 8?
3 and 3 would give 9 which is the closest to our constraints.
Both numbers cannot be similar however and have to have a decimal but the factors should be around 3 but not up to 4 as this would pass the 10.
3.5 * 2.5 = 8.75 would work.

Answer:
1) I just simply added the numerators because the denominators of both fractions are equal. As the denominators are same , I simply wrote 6 by taking the L.C.M of both denominators.
4)
[tex] \frac{5x - 3}{6} + \frac{x - 9}{6} [/tex]
[tex] = > \frac{5x - 3 + x - 9}{6} [/tex]

Today only, every sweatshirt is $4.25 less than normal price. Right now if you buy 5 sweatshirts, the total cost will be $106.25. What's the normal price of the sweatshirt?
Answer:
Step-by-step explanation:
The normal price of the sweatshirt will be $21.50 because if you divide $78.75 by 5 you get $15.75 for each sweatshirt then you add the $5.75 with will make the original price $21.50
Answer:
25.50
Step-by-step explanation:
You take 106.25 divided by 5 and you get the marked down price of one sweatshirt which is 21.25 so then you add 4.25 to that price and get 25.50.

A fraction becomes 4÷5 if 1 is added to both numerator and denominator. If, however, 5 is subtracted from both numerator and denominator , the fraction becomes 1÷2. Find tge fraction by using crammer rule.
Answer:
[tex]\dfrac{7}{9}[/tex]
Step-by-step explanation:
[tex]\dfrac{x+1}{y+1}=\dfrac{4}{5}\\\Rightarrow 5x-4y=-1[/tex]
[tex]\dfrac{x-5}{y-5}=\dfrac{1}{2}\\\Rightarrow 2x-y=5[/tex]
Putting it in matrix form
[tex]\begin{bmatrix}a_{1}&b_{1}\\a_{2}&b_{2}\end{bmatrix}{\begin{bmatrix}x\\y\end{bmatrix}=\begin{bmatrix}{c_{1}}\\{c_{2}}\end{bmatrix}\\\Rightarrow\begin{bmatrix}5 & -4\\2 & -1\end{bmatrix}\begin{bmatrix}x\\ y\end{bmatrix}=\begin{bmatrix}-1\\ 5\end{bmatrix}[/tex]
From Cramer's rule we have
[tex]x=\dfrac{\begin{vmatrix}c_1 &b_1 \\ c_2 & b_2\end{vmatrix}}{\begin{vmatrix}a_1 &b_1 \\ a_2& b_2\end{vmatrix}}\\\Rightarrow x=\dfrac{\begin{vmatrix}-1 &-4 \\ 5 & -1\end{vmatrix}}{\begin{vmatrix}5 &-4 \\ 2& -1\end{vmatrix}}\\\Rightarrow x=\dfrac{1+20}{-5+8}\\\Rightarrow x=7[/tex]
[tex]y=\dfrac{\begin{vmatrix}a_1 &c_1 \\ a_2 & c_1\end{vmatrix}}{\begin{vmatrix}a_1 &b_1 \\ a_2& b_2\end{vmatrix}}\\\Rightarrow y=\dfrac{\begin{vmatrix}5 &-1 \\ 2 & 5\end{vmatrix}}{\begin{vmatrix}5 &-4 \\ 2& -1 \end{vmatrix}}\\\Rightarrow y=\dfrac{25+2}{-5+8}\\\Rightarrow y=9[/tex]
Verifying the results
[tex]\dfrac{7+1}{9+1}=\dfrac{8}{10}=\dfrac{4}{5}[/tex]
[tex]\dfrac{7-5}{9-5}=\dfrac{2}{4}=\dfrac{1}{2}[/tex]
Hence, the fraction is [tex]\dfrac{7}{9}[/tex].
Solve for x:[tex]\frac{9}{x}= \frac{x}{16}[/tex]

Jane said that 6(64) = 6(50) + 6(14). Is she correct? Use the Distributive Property to explain your answer.
Answer:
Yes.
Step-by-step explanation:
6(64) = 6(50+14)
Using the Distributive Property, 6 needs to be multiplied by both 50 and 14.
6(50+14) = 6(50) + 6(14)
Thus, Jane is correct.
how do u add really big fractions
Answer:
It depends on your situation
Step-by-step explanation:
If you have a mixed fraction, for example: 5 23/3000 + 101 777/3000 you would have to make them irrational numbers and add them. Like so: 3000x5 = 15000. 15000+23 = 15023. 15023/3000. Same process but this time you get 303777/3000. You then add the numerators (top numbers) and you'll get the sum over 3000.
For regular fractions you simply add the numerators. If your denominators are not the same, you need to find a common term that both can fit into. If the denominators are not the same, no matter the size of the fraction, you cannot add it.
12) Find the sum, S7 for the geometric series {1 + 5 + 25 + - + 15625).
[A] S, = 19531
[B] S, = 16536
[C] Sy = 15631
D] S, = 31256
[E] None of these
Understanding:
The sum of a geometric series is, [tex]a+ar+ar^2+ar^3+...[/tex], with a being the start point and r is the common ratio. We can also use the following formula to make life easier [tex]S_n=a\frac{1-r^n}{1-r}[/tex], a is your start point, r is the common ratio, and n is the number of terms, which in our case is S7.
Solution:
Our start point is 1, [tex]a=1[/tex],
The common ratio is 5, [tex]r=5[/tex],
And finally, the number of terms is 7, [tex]n=7[/tex].
[tex]S_n=a\frac{1-r^n}{1-r} \\=(1)\frac{1-(5)^{(7)}}{1-(5)} \\=\frac{1-78125}{1-5} \\=\frac{-78124}{-4}\\=19531[/tex]
The answer is [A] 19531.

the sum of 2 numbers is 49. Twice the smaller number is 97 less than 3 times the larger number. What are the numbers?
Answer:
let the larger and smaller number be x and y respectively
first condition
x + y = 49
second condition
3x = 2y+97
3x-2y =97
Multiplying first condition by two and adding both equations
2x + 2y = 98
3x -2y = 97
5x = 195
x = 195/5 = 39
putting the value of x in
x + y = 49
y = 49 -39 = 10

Answer:
$0.85
Step-by-step explanation:
Given that,
Price of 10 tacos for $8.50
We need to find the charge for 1 taco.
We can find it using the unitary method.
10 tacos = $8.50
1 taco = [tex]\dfrac{8.5}{10}[/tex] = $0.85
Hence, restaurant A charge $0.85 for 1 taco.

Veronica is shopping for school clothes. She wants to buy pants and shirts. The cost of her clothes can be found using the expressions 30x+ 25y where x is the number of pants and y is the number of shirts. She will also pay 8 tax. If Veronica buys eight shirts and two pairs of pants use the expression from question 4 to determine the total cost of the bill including 8% tax
Answer:
$280.80
Step-by-step explanation:
Given:
C = 30x+ 25y
Where,
C = total cost
x = number of pants
y = number of shirts.
If Veronica buys eight shirts and two pairs of pants
C = 30x + 25y
= 30(2) + 25(8)
= 60 + 200
= 260
C = $260
Sales tax rate = 8%
Amount of sales tax = 8% of $260
= 8/100 × 260
= 0.08 × 260
= $20.80
Total cost of the bill including 8% tax = $260 + $20.80
= $280.80

Answer:
a) y = -7/640x^2 +7/4x
b) y = -7/640(x -80)^2 +70
Step-by-step explanation:
a) Given the equation in standard form:
y = ax^2 +bx +c
we can use the points (0, 0), (80, 70), and (160, 0) to find the values of a, b, c.
a·0 +b·0 +c = 0
a·80^2 +b·80 +c = 70
a·160^2 +b·160 +c = 0
The first equation tells us that c=0, so we can write a reduced matrix for the last two equations. The augmented matrix is ...
[tex]\left[\begin{array}{cc|c}6400&80&70\\25600&160&0\end{array}\right][/tex]
A matrix solver finds the solution to be ...
a = -0.0109375 = 7/640, b = 1.75 = 7/4
The standard-form equation for Money's path is ...
y = -7/640x^2 +7/4x
__
b) Factoring out -7/64, we have ...
y = -7/640(x^2 -160x)
adding and subtracting the square of the x-coefficient, we have ...
y = -7/640(x^2 -160x +6400) +70
y = -7/640(x -80)^2 +70
