Answer:

Sally's method

Step-by-step explanation:

Something squared is a number times itself. The square root is the reverse. Michael's method is wronh because he is dividing by 2 (multiplying by½), which is not how you find the square root.

The total line length of cubes lined up would be approximately 1.6 x 10^7 cm.

To find the total line length of cubes lined up, we need to find the total number of cubes in the box and then multiply it by the side length of a cube.

We can find the total number of cubes in the box by dividing the volume of the box by the volume of a cube:

Volume of the box = 2 m * 4 m * 8 m = 64 m³

Volume of a cube = 8 cm³ = 8 x 10^-6 m³ (converting the cm³ to m³)

Number of cubes = 64 m³ / 8 x 10^-6 m³ = 8 x 10^6

Then we can multiply the total number of cubes with the side length of a cube to find the total line length of cubes lined up :

Therefore, Line Length = 8 x 10^6 * 8 cm

= 6.4 x 10^7 cm

= 1.6 x 10^7 cm.

Answer: 2 and

Step-by-step explanation: equation 2:

3(3x+4)-5=9x-2

9x+12-5=9x-2

9x+7=9x+-2

Subtract both sides by 9x

7=-2

This Is not true therefore there is no solution

Answer:

17/30

Step-by-step explanation:

2/5 + 1/6 = 17/30

Make them easier to add by making them have the same denominator.

2/5 = 12/30

1/6 = 5/30

12/30 + 5/30 = 17/30

Answer:

17/30

Step-by-step explanation:

First, we need to get the lowest common denominator, which is 30 (5 times 6 and 6 times 5) since we multiplied the denominators we have to multiply the numerators by the same numbers (6 and 5) now we get 12/30 + 5/30, which equals 17/30

Step-by-step explanation:

0.1315 with a bar over all numbers means that the pattern of digits under the bar repeats without end. So the number is 0.1315131513151315131513151315....... etc

There is a formula to kind of simply this but I do not think that is what you are asking for.

Answer:

[tex]\overline{0.1315}=\frac{1315}{9999}[/tex]

Step-by-step explanation:

The trick is that because there are 4 digits being repeated infinitely, then this is equivalent to 1315/9999 because of the four 9s.

The equation of line shown in figure is,

⇒ y = x - 4

The equation of line in point-slope form passing through the points

(x₁ , y₁) and (x₂, y₂) with slope m is defined as;

⇒ y - y₁ = m (x - x₁)

Where, m = (y₂ - y₁) / (x₂ - x₁)

Given that;

Two points on the line are (4, 0) and (0, -4).

Now,

Since, The equation of line passes through the points (4, 0) and (0, -4).

So, We need to find the slope of the line.

Hence, Slope of the line is,

m = (y₂ - y₁) / (x₂ - x₁)

m = (- 4 - 0) / (0 - 4)

m = - 4 / -4

m = 1

Thus, The equation of line with slope 1 is,

⇒ y - 0 = 1 (x - 4)

⇒ y = x - 4

Therefore, The equation of line is,

⇒ y = x - 4

Answer:

200 tickets.

Step-by-step explanation:

85% = 85/100 = 0.85

170/0.85 = 200

= 200

Check:

200*0.85 = 170

Answer: hope this helps ♡

200 tickets were originally put up for sale.

Step-by-step explanation:

85% = 170

(we divide 85 and 170 by 85)

1% = 2

(now multiply 1 and 2 by 100)

100% = 200

(double check: 85% from 200 → (85×200) ÷ 100 = 170 ✓)

Answer:

150 workers are at the company

Step-by-step explanation:

If 20% of the workers is equal to 30 workers than in order to find 100% of the worker you need to multiply the percentage with a number that makes it 100% and then multiply that number to the 30 workers so

20% * 5 = 100%

30 * 5 = 150

so 100% of the workers is equal to 150 workers
