Event A: Spinning green or yellow on the spinner shown Event B: Rolling an odd number on a number cube What is P(A and B)?
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:114
Step-by-step explanation:
i am smart
The percentage of water in fresh mushrooms is 10 percent.
What is percentage?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.

20 - [(8 + 6) divide by 2]
Answer:
13
Step-by-step explanation:
As per the BODMAS, 8+6=14
14/2=7
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.

Step-by-step explanation:
A city just opened a new playground for children in the community. An image of the land that the playground is on is shown.
A polygon with a horizontal top side labeled 45 yards. The left vertical side is 20 yards. There is a dashed vertical line segment drawn from the right vertex of the top to the bottom right vertex. There is a dashed horizontal line from the bottom left vertex to the dashed vertical, leaving the length from that intersection to the bottom right vertex as 10 yards. There is another dashed horizontal line that comes from the vertex on the right that intersects the vertical dashed line, and it is labeled 12 yards.
What is the area of the playground?
900 square yards
855 square yards
1,710 square yards
1,305 square yards
Answer:
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.

A circular circus tent has a diameter of 5 meters. What is the approximate area of the floor of the circus tent? Use 3.14 for pi.
Answer:
[tex]\text{A}=19.6 \ \text{m}^2[/tex]
Explanation:
We are given a circular circus tent
diameter = 5m
we know that
[tex]\text{radius}=\dfrac{\text{diameter}}{2}[/tex]
[tex]\text{radius}=\dfrac{\text{5}}{2}[/tex]
[tex]\text{radius}=2.5[/tex]
so, [tex]\text{r}=2.5[/tex]
now, we can use area formula
[tex]\text{A}=3.14(\text{r})^2[/tex]
now, we can plug values
[tex]\text{A}=3.14(\text{2.5})^2[/tex]
[tex]\text{A}=19.625[/tex]
so,
[tex]\text{A}=19.6 \ \text{m}^2[/tex]
Answer:
Step-by-step explanation:
The approximate area of the floor of the circus tent is 19.625 square metres.
The area to be found is that of a circle. The data given in the question is
the diameter of the circle. To calculate the area of the circle, we need to first find the radius. The radius is half of the diameter. By calculation, d/2, we get 5/2= 2.5m. The formula for finding the area of the circle is πR². By substituting the values, we get A(Area) = 3.14 (given) * 2.5 * 2.5 square metres. The area comes out to be 19.625 square metres.

The Box-and-Whisker Graph shows the heights, in inches, of children between ages of 7 and 14. Between which two numbers would we find the lower 50% of the data?
A. Between 52 and 61 B. Between 61 and 64.5 C. Between 61 and 72 D. Between 57.5 and 61
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)

Given d || e.
∠1 and ∠2 are ___
vertical
corresponding
complementary
supplementary
angles.
∠6 and ∠8 are ___ angles. (same options as first one)
∠1 and ∠5 are ___ angles. (same options as first one)
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

Answer: L 38
Step-by-step explanation:
total 84
Answer: 48 small shirts
108 medium shirts
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
And 48 + 108 + 84 = 240
