Answer:
1. .09 repeating 2. 6 5/9
Step-by-step explanation:
to turn a fraction into a decimal you divide the top number of a fraction by the bottom one. To convert an improper fraction to a mixed fraction, divide the numerator by the denominator, write down the quotient as the whole number and the remainder as the numerator on top of the same denominator

How do I simplify (9 square 3-4 square+2)-(x square 3+3 square 2 +1
Answer:
8x³ - 3x² - 4x + 3
Step-by-step explanation:
first, eliminate the parenthesis. you can just drop the first set, but you have to distribute the negative through the second set.
9x³ - 4x + 2 - x³ - 3x² +1
then combine like terms (terms with the same exponent)
8x³ - 4x + 3 - 3x²
then put it in the correct order
8x³ - 3x² - 4x + 3

which is an equivalent fraction to 0.265
Answer:
32/125
Step-by-step explanation:
Answer:
Steps to convert 0.265 into a fraction:
Write 0.265 as
0.265/1
Multiply both the numerator and denominator by 10 for each digit after the decimal point:
0.265/1 =
0.265 x 1000/1 x 1000
= 265/1000
In order to reduce the fraction we find the Greatest Common Factor (GCF) for 265 and 1000. A factor is just a number that divides into another number without any remainder.
The factors of 265 are: 1 5 53 265
The factors of 1000 are: 1 2 4 5 8 10 20 25 40 50 100 125 200 250 500 1000
The Greatest Common Factor (GCF) for both 265 and 1000 is: 5
Now to reduce the fraction we divide both the numerator and denominator by the GCF value.
265/1000 = 265 ÷ 5/1000 ÷ 5
=
53/200
Simply the answer is 53/200

Answer:
The graph is linear and shaded below the line.
Step-by-step explanation:
It looks like the graph is linear, since the line is straight and continues on forever in both directions. It's not quadratic or absolute value, since quadratic graphs are curved and absolute value graphs branch off in two directions.
If you look at the Desmos graph attached, the shade is below the line, not above the line.
Finally, (0, 0) is not a solution since this point is not part of the shaded section of the graph.
Hopefully this helps! If you need further clarification, let me know!
4^3 • 5^3 and 20^3, Are the expressions equivalent? Yes or no?
Answer:
Yes
Step-by-step explanation:
4³ × 5³
(4 × 5)³
=20³
Both are equivalent
Hey there!
4^3 * 5^3 = ?
4^3
= 4 * 4 * 4
= 16 * 4
= [64]
5^3
= 5 * 5 * 5
= 25 * 5
= [125]
125 * 64
= [8,000]
20^3
= 20 * 20 * 20
= 400 * 20
= 8,000
8,000 = [8,000]
Therefore, this statement is TRUE so your answer is: [YES]
Good luck on your assignment and enjoy your day!

Six plus -2 times a number is the same as 26 plus six times the same number.
Step-by-step explanation:
let the number be x
and according to question,
six + 2 times a number = 2x + 6
26 + 6 times a number = 6x + 26
→ 2x + 6 = 6x + 26
→ -6x + 2x = 26 - 6
→ -4x = 20
→ x = 20/4 = 5
→ x = 5
therefore, the number is 5.

Step-by-step explanation:
1. First, we should realize that the angle with 5x + 7 and the angle with 8x - 71 are alternate exterior angles, so they're congruent.
This means that 5x + 7 = 8x - 712. (Solving)
Step 1: Subtract 8x from both sides.
[tex]5x + 7 - 8x = 8x - 71 - 8x[/tex] [tex]-3x + 7 =-71[/tex]Step 2: Subtract 7 from both sides.
[tex]-3x + 7 - 7 = -71 - 7[/tex] [tex]-3x = -78[/tex]Step 3: Divide both sides by -3.
[tex]\frac{-3x}{-3}=\frac{-78}{-3}[/tex] [tex]x = 26[/tex]Step 4: Check if solution is correct.
[tex]5(26)+7=9(26)-71[/tex] [tex]130 + 7 = 208 - 71[/tex] [tex]137 = 137[/tex]Therefore, x = 26.

(Show answer )
A balloon is being inflated mechanically in such a way that the volume is increasing at a constant rate of 15 cm3 /s. If the volume of the balloon was originally 30 cm3, determine the average rate of change of the volume of the balloon with respect to the radius of the balloon, to the nearest centimetre cubed per centimetre, between 0 s and 10s, and between 10 s and 20 s.Discuss the following question:Is the rate of change of volume with respect to radius constant?
The magnitude of the volume of the balloon increases at a faster rate than
the radius of the balloon.
The rate of change of the volume of the balloon with respect to radius is not constant.Reasons:
The rate at which the volume of the balloon is increasing, [tex]\dfrac{dV}{dt} = 15 \ cm^3/s[/tex]
The initial volume of the balloon, V = 30 cm³
The rate of change of the volume of the balloon with radius is given as follows;
[tex]\dfrac{\Delta V}{\Delta r}= \dfrac{V_2 - V_1}{r_2 - r_1}[/tex]
[tex]Volume \ of \ the \ balloon, \ V = \dfrac{4}{3} \cdot \pi \cdot r^3[/tex]
[tex]V = 30 + \dfrac{dV}{dt} \times t[/tex]
∴ V = 30 + 15·t
At t = 0, V = 30 cm³
Where;
[tex]r =\sqrt[3]{ \dfrac{3 \cdot V}{4 \cdot \pi} }[/tex]
When V = 30
[tex]r =\sqrt[3]{ \dfrac{3 \times 30}{4 \cdot \pi} } \approx 1.93[/tex]The radius, r ≈ 1.93 cm.
At t = 10 s., we have;
V = 30 + 15 × 10 = 180
[tex]r =\sqrt[3]{ \dfrac{3 \times 180}{4 \cdot \pi} } \approx 3.5[/tex]At t = 20 s., we have;
V = 30 + 15 × 20 = 330
[tex]r =\sqrt[3]{ \dfrac{3 \times 330}{4 \cdot \pi} } \approx 4.29[/tex]Therefore;
Between 0 s. and 10 s., we have;
[tex]\dfrac{\Delta V}{\Delta r}=\dfrac{180 - 30}{3.5-1.93} \approx 96[/tex]Rate of change of the volume of the balloon with respect to the radius of the balloon to the nearest centimeter, between 0 s and 10 s is 96 cm³/cm.
Between 10 s. and 20 s., we have;
[tex]\dfrac{\Delta V}{\Delta r}=\dfrac{330 - 180}{4.29 - 3.5} \approx 190[/tex]Between 10 s. and 20 s. the rate of change is approximately 190 cm³/cm.
Therefore;
The rate of change of the volume of the balloon with respect to radius is not constant, but increases as the volume of the balloon increases.

Do not use decimals in your answer.
5x = 16
Step-by-step explanation:
¾ x - 2 = ⅖
¾ x = ⅖ + 2
¾ x = (2 + 10)/5
¾ x = 12/5 → (multiplied by 20)
20(¾)x = 20(12/5)
5(3)x = 4(12)
15x = 48 → (divided by 3)
5x = 16
