Answer:
1. 343
2. 64
3. 81
4. 12.25
Step-by-step explanation:
Answer:
[tex]7^{3}[/tex] = 343
4 cubed = 64
[tex]9^{2}[/tex] = 81
[tex](3.5)^{2}[/tex] = 12.25
Step-by-step explanation:
[tex]7^{3}[/tex] is the same thing as 7 * 7 * 7.
7 * 7 = 49
49 * 7 = 343
4 cubed can be written as [tex]4^{3}[/tex], which is the same as 4 * 4 * 4.
4 * 4 = 16
16 * 4 = 64
[tex]9^{2}[/tex] is the same as 9 * 9.
9 * 9 = 81
[tex](3.5)^{2}[/tex] is the same as 3.5 * 3.5.
3.5 * 3.5 = 12.25

The ratio of BMX bikes in a sporting goods store to mountain bikes is 3 to 2. The store
has 90 BMX bikes. How many mountain bikes does the store have?
Answers
BMX: 3 to 2
BMX:90 to 60
90x2=180 180÷3=60
Answer: 60
The store has 60 mountain bikes if there is ratio of BMX bikes in a sporting goods store to mountain bikes is 3 to 2.
What is Ratio?An ordered pair of numbers a and b, written a / b where b does not equal 0 is called ratio.
The ratio of BMX bikes to mountain bikes in the store is 3 to 2.
Which means that for every 3 BMX bikes, the store has 2 mountain bikes.
It is given that the store has 90 BMX bikes.
Let us set up a proportion to find the number of mountain bikes:
3 BMX bikes / 2 mountain bikes = 90 BMX bikes / x mountain bikes
where x is the number of mountain bikes.
Now solve for x
3 BMX bikes × x mountain bikes = 2 mountain bikes × 90 BMX bikes
3x = 180
Divide both sides by 3
x = 60
Therefore, the store has 60 mountain bikes.

Mt. Everest, the highest elevation in Asia, is 29,028 feet above sea level. The Dead Sea, the lowest elevation, is 1,312 feet below sea level. What is the difference between these two elevations? Show your work
Answers
Answer:
30,340 feet above sea level is the correct answer.
Step-by-step explanation:
To find the difference to between the two sea levels, subtract the lowest quantity (or the elevation of the Dead Sea) to the largest quantity (or the elevation of Mt. Everest.)
However, in this situation, you must also add the quantity of the above sea level to the subtraction, since the lower quantity is above sea level.
29,028 - 29,028 = 0
Now, we must subtract the lower quantity of 1,312.
0 - 1,312 = -1,312
If this was to be represented on a number line, the difference between our work relates to the absolute value, or the amount of spaces a number is from 0. Even though this is a negative number, you can take away the sign (if there is any) from in front of the number, and the absolute value will still be 1,312.
To find the total difference, add 29,028 to 1,312.
29,028 + 1,312 = 30,340
Therefore, our final answer is 30,340 feet above sea level.

(graph, table, equation) = (1, 5, 2), (2, 3, 1), (3, 2, 4), (4, 4, 5), (5, 1, 3)
Step-by-step explanation:
The graphs have the following (slope, intercept), so can be easily matched with the corresponding equation.
(1/2, 1), (2, -1), (1, 2), (1/2, -1), (-2, -1)
We can look at the points in the tables to see which graph they appear on.
Table 1, (-2, 3) is on graph 5
Table 2, (-3, -1) is on graph 3
Table 3, (-1, -3) is on graph 2
Table 4, (-2, -2) is on graph 4
Table 5, (4, 3) is on graph 1

Hey everyone i need your help again what's 3(11x + 5) = 279
Answers
Answer:
x = 8
Step-by-step explanation:
We can use PEMDAS to solve algebraic equations:
Parentheses
Exponents
Multiplication/Division
Addition/Subtraction
First, we have parentheses in this equation, so distribute
3(11x) + 3(5) = 279
Next, because there are no exponents, multiply
33x + 15 = 279
To isolate x, subtract 15 from both sides
33x + 15 - 15 = 279 - 15
33x = 264
Then divide both sides by 33
x = 8
Use the identity (x+y)(x2−xy+y2)=x3+y3 to find the sum of two numbers if the product of the numbers is 28, the sum of the squares is 65, and the sum of the cubes of the numbers is 407.
Answers
Answer:
Step-by-step explanation:
1) f(x) = x+y , xy = 49 --> f(x) = x+49/x
f '(x) = 1-49/x2 , x = ±√49 , choose x = +7
y = 49/x = 7
smaller = 7
larger = 7
2) Vertical Distance is difference between the two functions
V(x) = x+56 - x2, V '(x) = 1 -2x --> x = 1/2 --> V(1/2) = 56.25 <---Max Vertical distance
Boundary at -7 and 8 are less
3) I googled the equation, it is really y(n) = kn/(49+n2)
y '(n) = (k(49+n2) - 2kn2)/(49+n2) , Setting to zero, k(49+n2) -2kn2 = 0 , n = 7
4) Let x and y be the sides of the rectangle. A = xy = 37.5 Million or y = 37.5/x
The length of the fences is f(x) = 2x + 3y = 2x+112.5/x
f '(x) = 2-112.5/x2 --> x = √56.5 = 7.5 and y = 37.5/7.5 = 5 then scale by √Million
smaller = 5000 ft and larger = 7500 ft
this took me ages to work out so hopefully it helped
Answer:
x + y = 11
Step-by-step explanation:
xy = 28
x² + y² = 65
x³ + y³ = 407
(x + y)(x² - xy + y²) = x³ + y³
(x + y)(x² + y² - xy) = x³ + y³
(x + y)(65 - 28) = 407
37(x + y) = 407
x + y = 407÷37
x + y = 11

~Combine like terms
2x² - x - 15 = 14
