It’s just the same as if there were no decimal point. but if there isn’t a number in the quotient on the left of the decimal like #15, then you just place a 0 and continue to the next dividend which is 50.

Answer:

Slope is 3/2

Step-by-step explanation:

If you're going from point (1,4) to point (-3,-2), then your answer slope = -3/2.

If you're going from -3, -2 to 1,4 then it's 3/2 because you are going up 3, over 2 each time.

$\frac{rise}{run} = \frac{3}{2}$

9. The theater club of a local high school is planning a production. The amount of time t needed to assemble the set is inversel

Vsevolod [243]

Answer:

The situation that represents this situation is:

$t = \frac{60}{n}$

Step-by-step explanation:

The amount of time t needed to assemble the set is inversely proportional to the number people n working.

This means that:

$t = \frac{k}{n}$

In which k is the constant of proportionality.

Twelve people can assemble the set in 5 hours.

This means that for $n = 12, t = 5$ . We use this to find k.

$t = \frac{k}{n}$

$5 = \frac{k}{12}$

$k = 12*5 = 60$

Write an equation to represent the situation.

$t = \frac{60}{n}$

Kelly was baking bread but could only find her ⅛ cup measuring cup. She needs ¼ cup sugar, ¾ cup whole wheat flour, and ½ cup al

Nataly_w [17]

Answer:

Number of 1/8 cups of sugar needed = 2

Number of 1/8 cups of whole wheat flour needed = 6

Number of 1/8 cups of all purpose flour needed = 4

Step-by-step explanation:

Recipes Kelly needs:

Sugar = 1/4 cups

Whole wheat flour = 3/4 cups

All purpose flour = 1/2 cups

She could only find her ⅛ cup measuring cup.

How many ⅛ cups will she need for each ingredient?

Number of 1/8 cups of sugar needed = cups of Sugar needed / 1/8 cups

= 1/4 ÷ 1/8

= 1/4 × 8/1

= 8/4

= 2

Number of 1/8 cups of sugar needed = 2

Number of 1/8 cups of whole wheat flour needed = cups of whole wheat flour needed / 1/8 cups

= 3/4 ÷ 1/8

= 3/4 × 8/1

= 24/4

= 6

Number of 1/8 cups of whole wheat flour needed = 6

Number of 1/8 cups of all purpose flour needed = cups of all purpose flour needed ÷ 1/8 cups

= 1/2 ÷ 1/8

= 1/2 × 8/1

= 8/2

= 4

Number of 1/8 cups of all purpose flour needed = 4
