a trapezoid with an area of 166.75 in has bases that measure 21 in and 8 in find the height of the trapezoid
Answers
The area of trapezoid is calculated as -
Area of trapezoid = [tex] \frac{a + b}{2} X height [/tex]
Here, a = base 1
b = base 2
Height is the height of trapezoid.
It is given that,
Area of trapezoid = 166.75 in
Base 1, a = 21 in
Base 2, b = 8 in
Area of trapezoid = [tex] \frac{a + b}{2} X height [/tex]
166.75 in = [tex] \frac{21 in + 8 in}{2} X height [/tex]
Height = [tex] \frac{ 166.75 in}{14.5}
Height = 11.5 in
Thus, height of trapezoid = 11.5 In
kendra flips a coin 3 times what is the probability that she flips tails all 3 times
Answers
To find the probability of flipping tails all three times, we need to consider that each flip of a fair coin has a probability of 0.5 of landing on tails.
Since the coin flips are independent events (the outcome of one flip doesn't affect the outcome of another flip), we can simply multiply the probability of each individual flip.
So, the probability of flipping tails three times in a row is:
P(Tails, Tails, Tails) = P(Tails) × P(Tails) × P(Tails)
P(Tails, Tails, Tails) = 0.5 × 0.5 × 0.5
P(Tails, Tails, Tails) = 0.5³
P(Tails, Tails, Tails) = 0.125
So, the probability that Kendra flips tails all three times is 0.125 or18.
The probability of flipping tails on a fair coin is 0.5 (or 1/2) since there are two equally likely outcomes, heads or tails. When flipping a coin three times, each flip is independent, meaning the outcome of one flip doesn't affect the outcome of another.
To find the probability of flipping tails all three times, we multiply the probability of each individual flip.
So, 0.5 (tails on the first flip) times 0.5 (tails on the second flip) times 0.5 (tails on the third flip) equals 0.5³ = 0.125.
Therefore, the probability that Kendra flips tails all three times is 0.125 or 1/8.

Kendra flips a coin 3 times what is the probability that she flips tails all 3 times.

the cost of running an appliance varies jointly as the number of watts used, the hours of operation, and the cost per kilo-watt hour. A 6000 watt convection oven operates for 10 minutes for 15 cents at a cost of 7.5 cents per kilo-watt hour. what is the cost of cooking two meals if each meal takes 70 minutes to make?
Answers
The cost of cooking two 70-minute meals on a 6000-watt appliance with a kilo-watt rate of 7.5 cents will be roughly $1.05.
Explanation:Your question relates to the calculation of the cost of running an appliance based on its power, time of use, and the cost per kilo-watt hour. When evaluating power and energy consumption, we use an equation for energy, which states that E = Pt, where E is the energy (in kilo-watt hours), P is the power (in kilo-watts), and t is the time (in hours).
First, to find the cost, we need to convert everything to respective units. The 6000 watts is equivalent to 6 kilowatts (kw), and 10 minutes is equivalent to 10/60 or approximately 0.167 hours. The cost per kilo-watt hour is 7.5 cents.
The energy consumed would thus be E = Pt = (6kw)(0.167 hr)= 1kwh. The cost of running the appliance for 10 mins is (1kwh)(7.5 cent/kwh) = 7.5 cents.
To cook one meal, with a time of 70 minutes (or approximately 1.167 hours), we will have E = Pt = (6kw)(1.167 hr)= 7kwh. The cost of cooking one meal therefore would be (7kwh)(7.5 cent/kwh) = 52.5 cents.
Finally, to cook two meals, you would just double this cost, resulting in 2 * 52.5 cents = 105 cents or $1.05.

Josh wants to determine the number of loaves of bread he can bake using the 13 and one-third cups of flour he has.
13(1/3) can be written as,
= 13(1/3)
= 40/3
Each loaf requires 3 and four-fifths cups of flour.
This can be written as,
3(4/5) cups of flour = 1 loaf
19/5 cups of flour = 1 loaf
Multiply 5/19 on both sides.
1 cup of flour = 5/19 loaf
Multiply 40/3 on both sides.
40/3 cups of flour = 40/3 x 5/19 loaf

the ratio of boy to girls in 8th grade is 5 to 3 ,how many girls are there in 8th grade if there are 80 students in 8th grade
Answers
------- = --- Note that 5+3 = 8. Thus, (5/8) of the 80 students are boys and
girls 3 (3/8) of the 80 students are girls. This comes out to 30 girls (and 50 boys) Note that 30+50=80 (students)
. Thus, the number of girls =30.
Let's denote the number of boys as 5x and the number of girls as 3x. According to the problem, the total number of students is the sum of both boys and girls:
5x + 3x = 80
Combining the terms, we get:
8x = 80
Now, solving for x:
x = 80 / 8
x = 10
Now that we know the value of x, we can find the number of girls:
Number of girls = 3x = 3 * 10 = 30
Therefore, there are 30 girls in the 8th grade.

1) For the Rocks of Isabella:
Mean = (Sum of all numbers)/Total numbers
So, Mean weight of Isabella's Rocks = 7.64
Median is the central value.
So, Median weight of Isabella's Rocks = 6
Mode is the most frequently occurring value.
So, Mode weight of Isabella's Rocks = 8.75
Range = Maximum - Minimum
So, Range weight of Isabella's rocks = 13.75
2) For Mateo's Rocks:
Mean = 8
Median = 6
Mode = 8
Range = 14.75
From the above data, we can see that the Range of Mateo's Rocks is more as compared to the Isabella's Rocks.
Thus, Range can be used be used to support the claim that Mateo’s rocks generally weigh more than Isabella’s rocks.

equation is: width = area / length
width = 62.5 yd
Explanation:
For the first rectangle:
We have:
length = 75 yd and width = 60 yd
Therefore:
area = length * width
area = 75 * 60
area = 4500 yd²
For the second rectangle:
We have:
area = area of first rectangle = 4500 yd²
length = 72 yd
area = length * width
width = area / length ............> The required equation
width = 4500 / 72
width = 62.5 yd

How does the volume of a cylinder change when its diameter is quadrupled?
Answers
When the diameter of a cylinder is quadrupled, its volume increases by a factor of 4 because the volume is directly proportional to the square of the radius.
When the diameter of a cylinder is quadrupled, it means the diameter is multiplied by 4.
The formula for the volume of a cylinder is [tex]\(V = \pi r^2 h\)[/tex], where r is the radius and h is the height.
If the diameter is quadrupled, the radius would be doubled because the radius is half the diameter.
Let's denote the original radius as r and the new radius after quadrupling the diameter as 2r.
Substituting the new radius into the volume formula, we get:
Original Volume: [tex]\(V_1 = \pi r^2 h\)[/tex]
New Volume: [tex]\(V_2 = \pi (2r)^2 h = \pi (4r^2) h\)[/tex]
We can see that the new volume is 4 times the original volume [tex](\(V_2 = 4V_1\))[/tex].
So, when the diameter of a cylinder is quadrupled, its volume increases by a factor of 4.

Answers
1. You must apply the formula for calculate the area of a circle, which is:
A=πr^2
Where A is the area of the circle and r is the radius of the circle.
2. You have that the diameter is 6 feet, then the radius is:
r=D/2
r=3 feet
3. When you apply the formula shown above, you obtain:
A=9π feet^2
A=28.27 feet^2
The answer is: 28.27 feet^2
circumference = 2*pi*r = 6
solve for r:
r = 6/(2*pi) = 0.9554 ft
area = pi*r^2 = 0.9554*0.9554 * 3.14 = 2.866 sq. ft

To determine the number of cans of juice Mrs. Thomas needs to buy, calculate the volume of juice in one can and then divide the total required volume by the volume of one can. Mrs. Thomas will need to purchase at least 10 cans of juice.
To find out how many cans of juice Mrs. Thomas needs to buy, we need to calculate the volume of juice in one can first.
We use the formula for the volume of a cylinder: V = πr²h, where r is the radius and h is the height.Calculate the volume of one can: V = 3.142 x (4 cm)² x 11 cm = 554.632 cm³.Divide the total volume needed by the volume of one can: Number of cans = 5,100 cm³ / 554.632 cm³ = 9.19.Since you can't buy a fraction of a can, Mrs. Thomas will need to buy at least 10 cans of juice.
