Explain how u can mentally find the sum of the fractions in exercise 3 without actually performing the calculations.

Answer: Not sure if this is correct, but I believe the answer is B.

Step-by-step explanation:

Event A Probability = 2/5

Event B Probability = 1/2

P(A and B) = 2/5 * 1/2

P(A and B) = 2/10 = 1/5

B. 1/5

Answer:

A. Between 52 and 61

Step-by-step explanation:

In this box and whisker plot Q1 represents the first quartile or the bottom 25% of all the data(25th percentile)

Q2 represents the second quartile and represents the lower  50% of all the data 50th percentile). The middle line represents the median of the data set.

Therefore the lower 50% of the data is found between 52 (lower limit) and 62(50th percentile)

Step-by-step explanation:

Answer:

∠1 and ∠2 are supplementary angles.

∠6 and ∠8 are vertical angles

∠1 and ∠5 are corresponding angles.

Step-by-step explanation:

∠1 and ∠2 lie on a straight line which will always add up to 180 degrees or supplementary.

∠6 and ∠8 lie opposite each other on the transversal (intersecting line) and are equal.

<1 and <2 are Supplementary angles

<1 and <5 are Corresponding angles

<6 and <8 are Vertical angles

Given that d II e

when a transversal intersects two parallel lines the following conditions are true:

Supplementary angles are those angles when the sum of two angles is equal to 180 degrees. Since <1 and <2 are on either side of the transversal their sum is equal to 180 degrees hence why it's a supplementary angle.

Vertical angles form 4 angles when a line intersects them and the two angles are opposite to each other. In this case <6 and <8 are opposite each other hence why they are vertical angles.

Corresponding angles are the angles that are in the same position on each of the parallel lines and on the same side of the transversal. In this case both <1 and <5 are on the same side of the transversal on each of the parallel lines hence why they are corresponding angles

By answering the presented question, we may conclude that Therefore rectangle 855 square yards is the closest response choice.

What is rectangle?

In Euclidean geometry, a rectangle is a parallelogram with four small angles. It may also be defined as a fundamental rule hexagon or one in which all of the angles are equal. Another alternative for the parallelogram is a straight angle. Four of the vertices of a square are the same length. A quadrilateral with four 90° angle vertices and equal parallel sides has a rectangle-shaped cross section. As a result, it is also known as a "equirectangular rectangle." A rectangle is sometimes referred to as a parallelogram due to the equal and parallel dimensions of its two sides.

The rectangle has a 20-yard base and a 10-yard height, hence its area is:

200 square yards = 20 yards x 10 yards

The triangle on the left has a 20-yard base and a 45-yard height (since the top side of the polygon is indicated as 45 yards), hence its area is:

450 square yards = 1/2 x 20 yards x 45 yards

210 square yards = 1/2 x 12 yards x 35 yards

As a result, the total playground area is:

860 square yards = 200 square yards plus 450 square yards plus 210 square yards

Therefore 855 square yards is the closest response choice.

well, for 3)

we have a cylinder with a hole in it, mind you that we don't have a height for it, so let's call our height "h".

so hmmm let's take the area of the circular rings atop and bottom, Check the picture below.  Then we'll take the lateral area of the cylinder.

now, we have a hole in the middle, a cylindrical hole, since we need the walls of that hole, that's simply just the area of the inner-cylinder.

The percentage of water in fresh mushrooms is 10 percent.

Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".

Given that, from 22 kilograms of fresh mushrooms, 2.5 kilograms of dry mushrooms are obtained, containing 12% water.

Let x% of water in fresh mushrooms.

Here, x% of 22 = (100-12)% of 2.5

x/100 ×22 = 88% of 2.5

22x/100= 88/100 ×2.5

22x=88×2.5

x=4×2.5

x=10%

Therefore, the percentage of water in fresh mushrooms is 10 percent.

84 Large shirts

Step-by-step explanation:

20% of 240 = 48

45% pf 240 = 108

45 + 20 = 65, 100 - 65 = 35

35% of 240 = 84

20-7=13

Answer: The answer is 13!

Step-by-step explanation:

The first thing that you have to do is use PEMDAS, and do the things in parentheses first. This is 8+6. This equals 14. Divide 14 by 2 to get 7. The final thing to do is 20-7, and this is 13. Thus the answer is 13.
