Answer:

Step-by-step explanation:

First of all, the estimate will be +, because (-)(-) = (+).

So the problem boils down to approx 1 1/2 times 5, which comes out to 7 1/2.

7 1/2 is a reasonable estimate.

Please, when answer choices are given you, share them.

State a true conclusion.
xxTIMURxx [149]

Answer:

The conclusion is "Plane R and Plane S form a line if they intersect."

Step-by-step explanation:

Consider the provided statements.

1) If two planes intersect, their intersection is a line.

2) Plane Rand plane S intersect.

  • If two points lie in a plane, then the line joining them lies in that plane.
  • If two planes intersect, then their intersection is a line.

For better understanding refer the figure:

There are two planes R and S, which intersect at the line l.

Since the given two planes intersect, the using the above fact we can say that their intersection is a line.

Thus, the conclusion is "Plane R and Plane S form a line if they intersect."

She exceeded her budget by $111

Leon is using the recipe shown.
stira [4]

He will use 11 and half cups of olive oil to use with 1 teaspoon of cinnamon.

Step-by-step explanation:

Given,

Olive oil used in recipe = 23 cups

Cinnamon used in recipe = 2 teaspoons

Ratio of cinnamon to olive oil in recipe = 2:23

Cinnamon Leon has = 1 teaspoon

Let x be the olive oil.

Ratio of available cinnamon to olive oil = 1:x

Using proportion;

Ratio of cinnamon to olive oil in recipe :: Ratio of available cinnamon to olive oil

2:23::1:x

Product of extreme = Product of mean

2*x=23*1\\2x=23

Dividing both sides by 2;

\frac{2x}{2}=\frac{23}{2}\\x=11.5

11.5 can also be written as 11\frac{1}{2}

He will use 11 and half cups of olive oil to use with 1 teaspoon of cinnamon.
