ivolga24 [154]

Answer:

Emiy would think that it is not the perfect tomato sauce because it has 12 cloves of garlic in every 900 mL of sauce and it should have 14.4 cloves of garlic in every 900 mL of sauce to be perfect.

Step-by-step explanation:

The statement indicates that for Emily the perfect tomato sauce have 8 cloves of garlic in every 500 mL. With that we can calculate the amount of cloves of garlic that a tomato sauce should have for Emily to consider it to be perfect using the rule of three:

8 cloves of garlic → 500 mL

             x              ← 900 mL

x= (8*500)/900= 14.4

According to this, the perfect tomato sauce would need to have 14.4 cloves of garlic in every 900 mL. As Raphael's tomato sauce only has 12, it means that Emily would think that it is not the perfect tomato sauce.

A rectangle is 5 times as long as it is wide. The perimeter is 70 cm. Find the dimensions of the rectangle. Round to the nearest
Naddika [18.5K]

Let the width = X, then the length would be 5x ( 5 times as long as the width).

The perimeter is adding the 4 sides.

x + x + 5x + 5x = 70

Combine the like terms:

12x = 70

Divide both sides by 12:

x = 70/12

x = 5.83

The width = 5.83 cm.

The length = 5 x 5.83 = 29.15

Now round each length to the nearest tenth:

5.8 and 29.2 cm.

The answer is d.

-14,-10,_,-2,2,6 missing sequence
OLga [1]

-14,-10,-6,-2,2,6

Answer by Mimiwhatsup: I could easily subtract -14 from -10 to find out the sequence so they are adding four each time. That means the pattern will continue going on like this 10, 14, 18, 22 and so forth.
