Answer:

\frac{20}{42}

Step-by-step explanation:

In order to find the answer to this question you just have to multiply the numerator and denominator by any integer.

In this case:

\frac{10}{21}

Multiply by 2:

10 \times 2=20

21\times2=42

\frac{10}{21} =\frac{20}{42}

Hope this helps.

Find the midpoint of the line segment whose endpoints are (3, 10) and (7, 8).
Stels [109]

Answer:

Option 2 is correct.

Step-by-step explanation:

Given the coordinates of lines segment (3, 10) and (7, 8). we have to find the mid-point of given line segment.

Mid-point formula states that if (x_1,y_1) and (x_2,y_2) are the coordinates of end points of line segment then the coordinates of mid-point are

(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})

∴ Coordinates of mid-point of line segment joining the points          (3, 10) and (7, 8) are

(\frac{3+7}{2},\frac{10+8}{2})=(\frac{10}{2},\frac{18}{2})=(5,9)

Hence, option 2 is correct.

a cup is 6.4 cm tall, not including the 0.6 cm lip. cups are stacked inside one another. select the function that represents the
Alja [10]

Answer: 20

H(c) = 6.4 + 0.6c

<u>6.4</u> is the constant.

When the height of the cups is <u>18.4</u> the function is:

18.4 = 6.4 + 0.6c

Then, you add <u>6.4</u> from both sides

18.4 - 6.4 + 6.4 = 6.4 + 0.6c - 6.4  + 6.4

Simplify

18.4 = 6.4 + 0.6c

Switch sides

6.4 + 0.6c = 18.4

Multiply both sides by <u>10</u>

6.4 x 10 + 0.6c x 10 = 18.4 x 10

Refine

64 + 6c = 184

Subtract <u>64</u> from both sides

64 + 6c - 64 = 184 - 64

Simplify

6c = 120

Divide both sides by <u>6</u>

6c/6 = 120/6

c = <u>20</u>
