The first answer would be 3 out of 19 bc only the numbers less than 4 which is 1,2,&3 could possibly be drawn. then there are 8 even numbers out of the 19 that could possibly be drawn so the second answer would be 8 out of 19. fraction forms would be 3/19 and 8/19

Reptile [31]
Fresh Side : 4.41 / 7 = 0.63 per bagel
Value Mart : 3.60 / 5 = 0.72 per bagel

Fresh Side bagels are a better buy being that each bagel cost 0.63 compared to the bagels at Value Mart, which cost 0.72 per bagel.

An angle measures 40.2° more than the measure of its complementary angle. What is the measure of each angle?
vampirchik [111]
<h3>Solving for the measurements of Complementary Angles</h3><h3>Answer:</h3>

24.9^{\circ} and 65.1^{\circ}

<h3>Step-by-step explanation:</h3>

Recall that Angles that are complementary to each other add up to 90^{\circ}.

Let a be the measure of the complementary angle.

If an angle is 40.2^{\circ} more than its complementary angle, the measure of that angle is a +40.2. The sum of both angles are expressed a +(a +40.2) but since the have to add to 90 as they are complementary, a +(a +40.2) = 90.

Solving for a:

a +(a +40.2) = 90 \\ a +a +40.2 = 90 \\ 2a +40.2 = 90 \\ 2a +40.2 -40.2 = 90 -40.2 \\ 2a = 49.8 \\ \frac{2a}{2} = \frac{49.8}{2} \\ a = 24.9

Since the other angle measures a +40.2, we can plug in the value of a to find the measure of the angle.

Evaluating a +40.2:

a +40.2 \\ 24.9 +40.2 \\ 65.1

The measure of the angles are 24.9^{\circ} and 65.1^{\circ}

Explain why estimation is an important skill to know when adding and subtracting decimals.
Alla [95]
Estimation is a important skill to know when adding and subtracting decimals because if you estimate you have an idea on what your answer should be close to.

For example 4.68-2.38 could be 5-2 which is 3. 4.68-2.38 equals 2.3. 2.3 is close to 3.
