The diagonals of a kite are 22 feet and 33 long. what is the area ?
Answer:
A=363
Step-by-step explanation:
To solve the area of a kite you use
[tex] a = \frac{pq}{2} [/tex]
So 22×33=726 then divide that by 2 and you get 363.
The area of a kite with diagonals of 22 feet and 33 feet is calculated as half the product of its diagonals, resulting in an area of 363 square feet.
Explanation:The area of a kite can be calculated by taking the product of the lengths of its diagonals and dividing by two. In the case of the kite with diagonals of 22 feet and 33 feet, we use the formula: Area = (diagonal1 × diagonal2) / 2. Substituting the given lengths into the formula, we get Area = (22 × 33) / 2.
To find the area, we multiply 22 feet by 33 feet which equals 726 square feet. Then we divide by 2, so the area of the kite is 363 square feet.

B. 6.2^2 = 3.6^2 + 4.3^2 + 2(3.6)(4.3)cosN
C. 6.2^2 = 3.6^2 + 4.3^2 - (3.6)(4.3)cosN
D. 6.2^2 = 3.6^2 + 4.3^2 + (3.6)(4.3)cosN
Option A:
The equation used to solve for angle N is
[tex]6.2^{2}=3.6^{2}+4.3^{2}-2(3.6)(4.3) \cdot \cos N[/tex]
Solution:
Given data:
MO = 6.2 cm
ON = 4.3 cm
MN = 3.6 cm
To find the equation to solve for angle N:
Using cosine formula,
[tex]c^{2}=a^{2}+b^{2}-2 a b \cdot \cos C[/tex]
Here, a = 3.6 cm, b = 4.3 cm, c = 6.2 cm, and angle A = angle C
Substitute these in the formula, we get
[tex]6.2^{2}=3.6^{2}+4.3^{2}-2(3.6)(4.3) \cdot \cos N[/tex]
The equation used to solve for angle N is
[tex]6.2^{2}=3.6^{2}+4.3^{2}-2(3.6)(4.3) \cdot \cos N[/tex]

A town has accumulated 2 inches of snow, and the snow depth is increasing by 6 inches every hour. A nearby town has accumulated 8 inches, and the depth is increasing by 2 inches every hour. In about how many hours will the snowfall of the towns be equal?
Answer:
192 inches
Step-by-step explanation:
I dont know I tried
It will take approximately 1.5 hours for the snowfall in both towns to be equal.
The question asks to determine when the snowfall in two different towns will be equal. The first town starts with 2 inches of snow and accumulates 6 inches every hour. The second town starts with 8 inches of snow and accumulates 2 inches every hour. To find when the depths will be equal, we need to set up an equation where the snow depths of both towns are set equal to each other and then solve for time (t).
Let t be the number of hours required for the snow depths to be equal.
For the first town: Initial depth + (Rate of snowfall * Time) = 2 inches + (6 inches/hour * t)
For the second town: Initial depth + (Rate of snowfall *Time) = 8 inches + (2 inches/hour *t)
Setting both expressions equal, we get: 2 + 6t = 8 + 2t. By solving for t, we subtract 2t from both sides and also subtract 2 from both sides to obtain: 4t = 6. Then we divide both sides by 4 to find t = 1.5 hours.
So, it will take 1.5 hours for the snow depths in both towns to be equal.

You have a jar of jelly beans in front of you
with 12 - lime, 17 - papaya, 5 - mango and 13
- bubble gum. What is the probability, as a
fraction, of selecting either a lime or bubble
gum followed by a papaya?
The probability of picking a lime or bubblegum jellybean followed by a papaya jellybean is 425/2162, which is approximately 0.196 when rounded to three decimal places.
Explanation:The subject of this question is probability, a mathematical concept. Here is how we would calculate the answer to the student's query:
First, add up the total number of jelly beans in the jar, which gives us 47 jelly beans (12 lime + 17 papaya + 5 mango + 13 bubblegum). The total probability of picking a lime or bubblegum jelly bean is the probability of picking lime or bubblegum jelly beans divided by the total number of jelly beans.
The probability of picking a lime or bubblegum jelly bean is 25/47 (12 lime + 13 bubblegum = 25; 25/47).
After picking a lime or bubblegum jellybean, there are now 46 jellybeans left. Hence the probability of picking a papaya jellybean is 17/46.
Now, to get the total probability of picking a lime or bubblegum jellybean followed by a papaya jellybean, you multiply these two probabilities together.
The result will be (25/47) × (17/46) = 425/2162, which can be simplified to approximately 0.196 when rounded to three decimal places.

The correct probability, as a fraction, of selecting either a lime or bubblegum followed by a papaya is [tex]\(\frac{25}{341}\)[/tex].
To find this probability, we need to calculate the probability of each individual event and then multiply them together because we are dealing with two independent events: first selecting a lime or bubblegum, and then selecting a papaya.
First, let's find the total number of jelly beans:
Total jelly beans = lime + papaya + mango + bubble gum
Total jelly beans = 12 + 17 + 5 + 13
Total jelly beans = 47
Now, let's calculate the probability of selecting either a lime or bubblegum:
Probability of selecting lime = Number of lime jelly beans / Total number of jelly beans
Probability of selecting lime = 12 / 47
Probability of selecting bubblegum = Number of bubblegum jelly beans / Total number of jelly beans
Probability of selecting bubblegum = 13 / 47
Since we want the probability of selecting either a lime or bubblegum, we add these probabilities:
Probability of lime or bubblegum = Probability of lime + Probability of bubblegum
Probability of lime or bubblegum = (12 / 47) + (13 / 47)
Probability of lime or bubblegum = 25 / 47
Next, we calculate the probability of selecting a papaya after selecting either a lime or bubblegum. Since we are not replacing the jelly bean after the first selection, the total number of jelly beans is now 46 (one less than before because one jelly bean has been removed).
Probability of selecting papaya = Number of papaya jelly beans / Total number of remaining jelly beans
Probability of selecting papaya = 17 / 46
Now, we multiply the probability of selecting either a lime or bubblegum with the probability of selecting a papaya:
Probability of lime or bubblegum followed by papaya = Probability of lime or bubblegum * Probability of papaya
Probability of lime or bubblegum followed by papaya = (25 / 47) * (17 / 46)
Finally, we simplify this expression:
Probability of lime or bubblegum followed by papaya = (25 * 17) / (47 * 46)
Probability of lime or bubblegum followed by papaya = 425 / 2162
This fraction can be simplified by dividing both the numerator and the denominator by their greatest common divisor, which is 1 in this case. So the fraction is already in its simplest form.
Therefore, the probability of selecting either a lime or bubblegum followed by a papaya is [tex]\(\frac{425}{2162}\).[/tex]However, upon re-evaluating the calculation, it seems there was an error in the simplification process. The correct simplification is:
Probability of lime or bubblegum followed by papaya = [tex]\(\frac{25}{341}\).[/tex]

There are two buses. Bus A can travel 125 miles in 3 hours,
and Bus B can travel 85 more miles than bus A within the
same time. What is the speed of Bus B?
mph.
The speed is the distance covered by an object at a particular time. The speed of bus B is 70 miles per hour.
What is speed?The speed is the distance covered by an object at a particular time. Therefore, it is the ratio of distance and time.
[tex]\rm{Speed = \dfrac{Distance}{Time}[/tex]
Given that Bus A can travel 125 miles in 3 hours. While Bus B can travel 85 more miles than bus A within the same time. Therefore, we can write,
Distance traveled by Bus B = 125 miles + 85 miles = 210 miles
Time is taken by Bus B = 3 hours
Now, the speed of the bus B can be written as,
Speed of Bus B = Distance Covered / Time taken
= 210 miles / 3 hours
= 70 miles per hour
