Answer:

Step-by-step explanation:

Question 1. 50% of what number is 100?

Number = x

50%x = 100

5x/10 = 100 (50% = 2/10)

5x = 1000 (Multiplying by 10 at both sides of the equation)

x = 200 (Dividing by 5 at both sides of the equation)

Part 50 Whole 100 Part 75 Whole 150 Part 100 Whole 200

Question 2. 25% of what number is 30?

Number = x

25%x = 30

x/4 = 30 (25% = 1/4)

x = 120 (Multiplying by 4 at both sides of the equation)

Part 25 Whole 30 Part 50 Whole 60 Part 75 Whole 90 Part 100 Whole 120

Question 3. What did you differently to find the whole using a ratio table?

Using a ratio table is a much more simple path to get the whole. I take it and just calculate the double of the information given to me for completing the next values in my table, until I get the part 100 and its correspondent whole.

40 POINTS!!!! ANSWER CORRECTLY PLZ

Grace [21]

Answer:

5. ○ $\displaystyle \frac{25}{48}$

4. ○ $\displaystyle \frac{25}{46}$

3. ○ $\displaystyle \frac{31}{100}$

2. ○ $\displaystyle \frac{3}{4}$

1. ○ $\displaystyle \frac{27}{50}$

Step-by-step explanation:

5. $\displaystyle \frac{25}{23 + 25} = \frac{25}{48}$

4. $\displaystyle \frac{25}{46} = \frac{25}{21 + 25}$

3. $\displaystyle Flat-out\:given\:to\:you$

2. $\displaystyle \frac{21 + 23 + 31}{100} = \frac{75}{100} = \frac{3}{4}$

1. $\displaystyle \frac{31 + 23}{100} = \frac{54}{100} = \frac{27}{50}$

On a coordinate plane, how are the locations of the points (-4 , 8) and (-4 , -8) related?

STALIN [3.7K]

Answer:

A. reflection across the y-axiss

Step-by-step explanation:

Given:

The locations of the two points are (-4 , 8) and (-4 , -8).

To find:

The relation between two points.

From the given points (-4, 8) and (-4 , -8), it is clear that the y-coordinates are same but the sign of x-coordinates are opposite.

If a figure is reflected across the y-axis, then we change the sign of x-coordinate and the y-coordinates remain same, i.e.,

$(x,y)$ → $(-x,y)$

For (-4,8)

$(-4,8)$ → $(-4,-8)$

So, it is reflection across the y-axis.

Therefore, the correct option is A.

What is the cross-sectional area of a wire if its outside diameter is 0.0625 inch?

Leno4ka [110]

Given that the diameter: d= 0.0625 inch.

So, radius of the wire : r = $\frac{0.0625}{2}$ = 0.03125 inch

Now the formula to find the cross-sectional area of wire ( circle) is:

A = πr²

= 3.14 * (0.03125)² Since, π = 3.14 and r = 0.03125

=3.14 * 0.000976563

= 0.003066406

= 0.00307 (Rounded to 5 decimal places).

Hence, cross-sectional area of a wire is 0.00307 square inches.

Hope this helps you!
