Answer:27/343 or 0.0787172
Step-by-step explanation:
First you need to place the exponent on both the numerator and the demonimator to make 3 to the power of 3 over 7 to the power of 3
Next you evaluate the numerator so 3 to the power of 3 is 27
and 7 to the power of 3 is 343 so your answer in fraction form is 27/343
you can also change into a decimal if you divide the fraction if you need to
Hope this helps
Answer:
[tex](\frac{27}{343})[/tex]
Step-by-step explanation:
This is what you start off with [tex](\frac{3}{7})^{3}[/tex]
[tex](\frac{3}{7})^{3}[/tex] is also equal to [tex](\frac{3}{7})(\frac{3}{7})}(\frac{3}{7})[/tex] because the original equation is [tex](\frac{3}{7})[/tex] multiplied by itself 3 times.
[tex](\frac{3}{7})(\frac{3}{7})}(\frac{3}{7})[/tex]
Multiply the first two fractions straight across
[tex](\frac{9}{49})(\frac{3}{7})[/tex]
Multiply the answer of multiplying the two fractions by [tex](\frac{3}{7})[/tex]
[tex](\frac{27}{343})[/tex]

PLEASE HELP- The time it takes for an object to follow certain distance can be calculated using the equation t=√2d/g where d represents distance and g represents the force of gravity on the object write the eqtion as a function of the distance and use 9.81 meters per second squared as the force of gravity calculate the distance the object will fall in 3 seconds label your answer.
Answer:
d= 44.145 m (meters)
Step-by-step explanation:
distance = (g*t²)/2
t=3 sec. d=? , g=9.81 m/s²
distance (d)=9.81*(3)²/2
d= 44.145 m
Show steps of how to factor (3x^2 + 5xy - 2y^2)
(3x² + 5xy - 2y²)
3x² + 5xy - 2y² (rewrite the expression) (write 5xy as a difference)
3x² + 6xy - xy - 2y² (factor the expression) (factor out 2x from the expression)
3x x (x + 2y) -y x (x + 2y) (factor the expression) (factor out x + 2y from the expression)
Solution : (x + 2y) x (3x - y)

The length of a rectangle is 2 feet less
than three times the width. If the
perimeter is 68 feet, what are the
dimensions of the rectangle?
The length of the rectangle is 25 feet and the width of the rectangle is 9 feet.
It is given that,
Length of a rectangle is 2 feet less than three times the width.Perimeter is 68 feet.Explanation:
Let [tex]x[/tex] be the width of the rectangle. Then the length of the rectangle is [tex]3x-2[/tex].
Perimeter of a rectangle is:
[tex]P=2(\text{length}+\text{width})[/tex]
[tex]68=2(3x-2+x)[/tex]
[tex]68=2(4x-2)[/tex]
[tex]68=8x-4[/tex]
Isolate the variable.
[tex]68+4=8x[/tex]
[tex]\dfrac{72}{8}=x[/tex]
[tex]9=x[/tex]
Now, the length of the rectangle is:
[tex]3(9)-2=27-2[/tex]
[tex]3(9)-2=25[/tex]
Thus, the length of the rectangle is 25 feet and the width of the rectangle is 9 feet.

six students out of 40 students In a class are absent what percentage of the students are absent
15%
Step-by-step explanation:
Absent= 6
Total student = 40
[tex] \frac{6}{40} \times 100 \\ \\ \frac{600}{40} = 15\%[/tex]
Step-by-step explanation:
Hey there!!
We can simply do it.
Here,
Total students =40
Absent students = 6
Now,
[tex]absent\% = \frac{no.asent}{total \: student} \times 100\%[/tex]
Keep all values.
[tex]absent\% = \frac{6}{40} \times 100\%[/tex]
= 15%
Therefore, the absent percentage is 15%.

Does 1/6, -3, V7, -6/5 or 4.5 come first when the numbers are listed from least to greatest? Explain.
Answer:
-3
Step-by-step explanation:
Given numbers:
1/6, -3, √7, -6/5, 4.5
The smallest one is chosen between the two negatives as all the rest are greater.
- 3 is smaller than - 6/5= -1.2 as 3 > 1.2So the answer is -3
Greetings from Brasil...
Let's look at each number
1/6 = 1 ÷ 6 = 0.16666....
- 3 = - 3
√7:
√4 < √7 < √9, so
2 < √7 < 3 the result of √7 is between 2 and 3
-6/5 = (- 6) ÷ 5 or 6 ÷ (- 5) = - 1.2
4.5 = 4.5
Writing the numbers in ascending order can tell:
- 3; - 6/5; 1/6; √7 and 4.5or (same values - approximated values):
- 3; - 1.2; 0.2; 2.5 and 4.5

How do I simplify this? I got to 2/(3/x)-1 but I don't know how to simplify that further. Please show steps.
(f o g) (x) means that we substitute 3/x into x for f(x)
2 / ((3/x) - 1)
We have to get rid of the fraction in the denominator. Multiply both the top and bottom by x
(f o g) (x) = [tex]\frac{2x}{3 - x}[/tex]. This is as simplified as it can get.
