∠E and ∠F are vertical angles with m∠E=8x+8 and m∠F=2x+38 . What is the value of x? Enter your answer in the box.
Answer:
x = 5
Step-by-step explanation:
We need to remember that vertical angles are opposite to each other when two lines cross. The vertical angles that result from two lines crossing have the same measure.
In this problem we have angle E which measures 8x + 8 and angle F which measure 2x + 38.
Since they are vertical angles, we know that they have the same measure and therefore we can equal them both and solve for x:
[tex]8x+8=2x+38\\8x-2x=38-8\\6x=30\\x=5[/tex]
Therefore, x = 5 (and ∠E = ∠F = 48)

Find the product of 20 x 9 x 5 tell which property you used
I used associative property and the product of 20 x 9 x 5 is 900.
What is associative property?"The associative property states that when an expression has three terms, they can be grouped in any way to solve that expression. The grouping of numbers will never change the result of their operation. The associative property is true for the cases of addition and multiplication. Neither the sum nor the product of the expression changes."
For the given product of 20 x 9 x 5
I am using the associative property.
(20 x 9) x 5 = 900
First multiply 20 x 9, which gives 180
(180) x 5 = 900
Next multiply 180 x 5, which gives 900.
Hence, I used associative property and the product of 20 x 9 x 5 is 900.

The average mass of a kernel of popcorn is 0.125 g. if 1 pound = 16 ounces, and 1 ounce = 28.3 g, then how many kernels of popcorn are there in 0.500 pounds of popcorn?
Final answer:
To find the number of kernels of popcorn in 0.500 pounds, first convert the weight to grams and then divide by the average mass of a kernel. The calculation gives an approximate result of 1811 kernels.
Explanation:
To determine the number of kernels of popcorn in 0.500 pounds, we need to convert the weight from pounds to grams and then divide by the average mass of a kernel.
First, let's convert pounds to ounces. Since 1 pound is equal to 16 ounces, we have:
0.500 pounds = 0.500 x 16 = 8 ounces.
Next, let's convert ounces to grams. Since 1 ounce is equal to 28.3 grams, we have:
8 ounces = 8 x 28.3 = 226.4 grams.
Finally, divide the total grams by the average mass of a kernel:
226.4 grams / 0.125 grams = 1811.2 kernels.
Therefore, there are approximately 1811 kernels of popcorn in 0.500 pounds.

What is the total displacement of a student who walks 3 blocks east, 2 blocks north, 1 block west and then 2 blocks south?
The total displacement of the student is 2 block east.
We know that displacement refers to less distance that shows the difference between the starting & the final position.Based on this,
y = 2 -2 = 0
x = 3 - 1 = 2
So, we can conclude that the total displacement of the student is 2 block east.

You randomly select 7 students from a class with 15 male and 20 female students. what is the probability that you will choose exactly 4 females?
To find the probability of selecting exactly 4 females out of 7 students, we need to use the hypergeometric distribution.
Explanation:To determine the probability of selecting exactly 4 females out of 7 students, we need to use the hypergeometric distribution. In this scenario, we have a population of 35 students (15 males + 20 females) and we want to select a sample of 7 students. The group of interest is the females, which consist of 20 students. Since we are selecting without replacement, we need to use the hypergeometric distribution formula:
P(X = k) = (C(K, k) * C(N-K, n-k)) / C(N, n)
where:
N = total population sizen = sample sizeK = number of successes in the populationk = number of successes in the samplePlugging in the values, we get:
P(X = 4) = (C(20, 4) * C(15, 7-4)) / C(35, 7)
Calculating the combinations, we find that P(X = 4) = 0.416

HELP PLEASE APPRECIATED Margarita is driving at the speed of s-4/ s^2- 9s + 20 miles per hour.
The distance Margarita covers in s-5/4 hours is ___ miles.
Give the answer in simplest form.
Only correct answers and please show your work so I can refer to it on my other problems. thank you.
The distance Margarita covers in [tex]\( \frac{s-5}{4} \)[/tex]hours is [tex]\( \frac{1}{4} \)[/tex] miles.
Given that Margarita is driving at the speed of [tex]\( \frac{s-4}{s^2 - 9s + 20} \)[/tex] miles per hour, we can express the distance function as:
[tex]\[ d(s) = \text{speed} \times \text{time} = \left( \frac{s-4}{s^2 - 9s + 20} \right) \times s \][/tex]
[tex]\[ d\left(\frac{s-5}{4}\right) = \left( \frac{s-4}{s^2 - 9s + 20} \right) \times \frac{s-5}{4} \][/tex]
Let's simplify this expression:
[tex]\[ d\left(\frac{s-5}{4}\right) = \frac{(s-4)(s-5)}{4(s^2 - 9s + 20)} \][/tex]
[tex]\[ d\left(\frac{s-5}{4}\right) = \frac{s^2 - 9s + 20}{4(s^2 - 9s + 20)} \][/tex]
[tex]\[ d\left(\frac{s-5}{4}\right) = \frac{1}{4} \][/tex]
