Answer:

D) 125x²¹- 64y³  

Step-by-step explanation:

A) x⁶ + 27y⁹ = (x²)³ + (3y³)³  - sum of cubes

B) 3x⁹ - 64y³ - the first term is not a cube

C) 27x¹⁵ - 9y³ - the second term is not a cube

D) 125x²¹- 64y³ = (5x⁷)³ - (4y)³ - difference of cubes

Answer: [tex]33.33\%[/tex]

Step-by-step explanation:

Given

Raju buy an old car for [tex]Rs\ 1,25,000[/tex]

He spent [tex]Rs\ 25000[/tex] on its repair

The selling price of the car  [tex]Rs\ 2,00,000[/tex]

So, the cost price is

[tex]\Rightarrow C.P.=1,25,000+25,000=Rs\ 1,50,000[/tex]

Here, [tex]S.P.> C.P.\quad \text{i.e. gain}[/tex]

Gain percent is

[tex]\Rightarrow \text{Gain percent}=\dfrac{2,00,000-1,50,000}{1,50,000}\times 100=\dfrac{50,000}{1,50,000}\times 100\\\Rightarrow \text{Gain percent}=33.33\ \%[/tex]

Answer:

[tex]y = 0.045x -0.445[/tex]

Step-by-step explanation:

Given

[tex](x_1,y_1)=(11,5\%)[/tex] ---- in 2011

[tex](x_2,y_2)=(15,23\%)[/tex] --- in 2015

Required

Linear equation for x years after 2000

First, calculate the slope

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

[tex]m = \frac{23\% - 5\%}{15 - 11}[/tex]

[tex]m = \frac{18\%}{4}[/tex]

[tex]m = 4.5\%[/tex]

[tex]m = 0.045[/tex]

The equation for x years after 2000 is:

[tex]y = m(x - x_1) + y_1[/tex]

[tex]y = 0.045(x - 11) + 5\%[/tex]

[tex]y = 0.045x - 0.495 + 0.05[/tex]

[tex]y = 0.045x -0.445[/tex]

Answer:

x=4

Step-by-step explanation:

5x-7=13

5x=13+7

5x=20

x=20/5

x=4

Answer:

x = 4

Step-by-step explanation:

5x - 7 = 13

add 7 to both sides:

5x - 7 + 7 = 13 + 7

5x = 20

divide both sides by 5

[tex]\frac{5x}{5} = \frac{20}{5}[/tex]

x = 4

Answer:

3x + 21

Step-by-step explanation:

3(x + 7)           Distribute

Answer:

3. -3

4. 4

Step-by-step explanation:

3 . so  [tex]h^{2} = g^{?+3} h^{2}[/tex], we cancel the [tex]h^{2}[/tex] out and it leaves us with [tex]1=g^{?+3}[/tex]

Which means ?+3=0, and ?=-3

4. so [tex]k^{?} = k^{4}[/tex], ?=4

Answer:

x ≤ [tex]\frac{7}{17}[/tex]

Step-by-step explanation:

multipy both sides by twelve

move the variable to the left side and change the sign

collect like terms

divide both sides by -17 and flip the inequality sign

Answer:

4 / 6

Step-by-step explanation:

Fred fraction = 2/3

Sarah formed a fraction by dividing her number line into 6 equal pieces. This is given as;

x / 6

Since her fraction is equal to that of fred, we have;

x / 6 = 2 / 3

x = 6 * 2 / 3 = 4

Sarah Fraction = 4 / 6

Answer:

2+8×6÷3-6 = 2+48÷3-6 = 2+16-6 = 12

Answer:

139

Step-by-step explanation:

180 = x + 64+45

therefore: x = 139

Answer:

x = 109

Steps:

the sum of triangle angles is 180, and since the x is an exterior angle then 180-(64+45) = 71 and since it is an exterior angle then 180-71 = 109.

Answer:

3880 degrees

Step-by-step explanation:

18 gon = 18 sides

The sum of the measures of the interior angle of any polygon is the number of sides minus 2 multiplied by 180.

⇒ 18 - 2 x 180

⇒ 16 x 180

⇒ 2880

Answer:

1 day because he has 100 machines not just one

Step-by-step explanation:

Answer:

I am not the best at math but I know that u can't change the bottom half of the fraction so it would just be four and then multiply the five and the three which would be fifteen. The answer would be 15/4ths. So you want to color in 15 boxes. Hopefully I could be of some kind of help to you!

Answer:

color in 15 boxes

15/32

Step-by-step explanation:

first off, the points are split so I'm only getting 12, just so that you know.

so 1/8x1/4 is 1/32, so each box is 1/32.

5/8x3/4=15/32 (multiply the top of the first with the top of the second and the bottom of the first with the bottom of the second)

so color in 15 boxes and the answer to the multiplication is 15/32

Hope I could help!

Answer:

37/56

Step-by-step explanation:

If Jisoo drank 3/8 of a quart of chocolate milk, and his friend Andrew drank 2/7 of the same quart, the amount they drank altogether will be the sum of the amount they drank individually

Total = 3/8 + 2/7

Find the LCM

Total = 3(7)+8(2)/56

Total = (21+16)/56

Total = 37/56

Hence they drank 37/56 of the quartz altogether

Answer:

13.5

Step-by-step explanation:

Tom made fruit punch for a party

He used the following amount of fruits

2 gallons of orange juice

= if 1 gallon is 4 quart then 2 gallon is 4×2= 8 quarts

3 pints of cranberry juice

= if 1 pint is 0.5 quart then 3 pints is 0.5×3 = 1.5 quarts

The amount of quartz he made can be calculated as follows

= 1.5 + 8 + 4

= 13.5

Hence he made 13.5 quarts of fruit punch

Answer:

70°, ,have a nice day

Answer:

∠BCO = 70°

Step-by-step explanation:

AO = CO = BO because all radii of the same circle are equal.

∠ACO = 20° because it is an isosceles triangle.

∠BCA = 90° because a triangle with it's hypotenuse being the diameter of a circle is a right triangle.

∠BCA - ∠ACO = ∠BCO

90° - 20° = 70°

∠BCO = 70°
