Let G be the event that a randomly chosen employee of a restaurant is a General Manager. Let S be the event that a randomly chosen employee of a restaurant works at a seafood restaurant. Identify the answer which expresses the following with correct notation: Given that the employee is a General Manager, the probability that a randomly chosen employee of a restaurant works at a seafood restaurant.
Using conditional probability, the expression is given by:

4 Twice the sum of two numbers is 36. If one of the numbers is 10, Twenty years from now, I will be 4 times as old as my present age. What is my present age
Answer:
7
Step-by-step explanation:
The sum of the two number is 10 + x, which when doubled equals 36. Divide the 36/2, which gets to 18. Move the 10 to the other side which gets 18-10 to get 8. 20 years from now, so add 20. 20+8 is 28. 4 times my present age. So do the inverse and you will get 28/4 which equals 7. You're present age is 7.

The rectangular screen on a laptop has an area of 375 cm ^ 2 Its width is 10 cm less than its length. What are the dimensions of the screen?
Answer:
lenght = 25 cm
widht = 15 cm
Step-by-step explanation:
Dimensions of the screen
375 = (l - 10) × l
375 = l² - 10l
l² - 10l -375 = 0
(l + 15)(l -25)
l = -15 or l = 25
lenght = 25 cm
widht = 25 - 10
widht = 15 cm

The fraction a/b is in simplest terms and equal to the following:((2020^3)-1)/((2021^3)+1) . What is a + b?
Consider the expression
[tex]\dfrac{x^3-1}{(x+1)^3+1}[/tex]
Factorize the numerator and denominator a difference/sum of cubes:
[tex]\dfrac{(x-1)(x^2+x+1)}{((x+1)+1)((x+1)^2-(x+1)+1)}[/tex]
Expand the denominator:
[tex]\dfrac{(x-1)(x^2+x+1)}{(x+2)((x^2+2x+1)-(x+1)+1)}=\dfrac{(x-1)(x^2+x+1)}{(x+2)(x^2+x+1)}=\dfrac{x-1}{x+2}[/tex]
since x = 2020, and clearly 2020² + 2020 + 1 ≠ 0, so we can cancel the factor of x ² + x + 1. This leaves us with
[tex]\dfrac{2020^3-1}{2021^3+1} = \dfrac{2020-1}{2020+2} = \dfrac{2019}{2022}=\dfrac{673}{674}=\dfrac ab[/tex]
so that a + b = 673 + 674 = 1347.

The weight of an object above the surface of the earth varies inversely with the square of its distance to the center of the earth. If an object weighs 50 pounds when it is 3960 miles from the center of the earth, what would its weight be when it is 3975 miles from the center of the earth?
Answer:
W = K m / R^2 expresses weight of ojject
W2 / W1 = (R1 / R2)^2 ratio of W2 to W1
W2 = W1 * (3960 / 3975)^2 = 50 * .992 = 49.62 lbs

Answer:
An equation is 92 + 2x = 180.
The congruent angles each measure 44°.
Step-by-step explanation:
1. If two angles in a triangle are congruent and unknown, we can represent that as 2x. That means 92 + 2x = 180.
2. To find the measure of each congruent angle, x, we have to solve the equation above.
Step 1: Simplify both sides of the equation.
[tex]2x + 92 = 180[/tex]Step 2: Subtract 92 from both sides.
[tex]2x + 92 - 92 = 180 - 92[/tex] [tex]2x = 88[/tex]Step 3: Divide both sides by 2.
[tex]\frac{2x}{2} = \frac{88}{2}[/tex] [tex]x = 44[/tex]x = 44 means that the congruent angles each measure 44°.
Answer: 92+2x=180
Step-by-step explanation:
180-92=88
88/2 = 44
x=44
HELPP! 7th grade math
Answer:
the length would be 3ft and the width would be 2ft
Step-by-step explanation:
this is because the scale is 1cm:4f ft therefore, 12/4=3 and 8/4=2 which is your final answer
Answer:
LENGTH - 3cm / WIDTH - 2cm
Step-by-step explanation:
Well first off, you would use the scale: 1 cm = 4 ft
With 12, you divide by 4. 12 ÷ 4 = 3
With 8, you also divide by 4. 8 ÷ 4 = 2
So, it would be 3 cm long and 2 cm wide.

Answer:
sales person A demonstrates better performance in all of the ratios we computed
Step-by-step explanation:
A: sales per attempt = $3.3M/167 ≈ $19.8k
sale value per sale made = $3.3M/109 ≈ $30.3k
sales made per attempt = 109/167 ≈ 65%
__
B: sales per attempt = $2.7M/163 ≈ $16.6k
sale value per sale made = $2.7M/97 ≈ $27.8k
sales made per attempt = 97/163 ≈ 60%

Step-by-step explanation:
I like to let a graphing calculator or spreadsheet do repetitive calculations. It is well worth the few minutes it takes to learn how to enter a formula into any of the available free spreadsheet programs. The Desmos graphing calculator is amazing in its versatility and usefulness.
There are a couple of things that can help make it easier to construct a table of values.
1) recognize the axis of symmetry for this quadratic is ...
x = -b/(2a) = -25/(2(-5)) = 2.5
So, choosing numbers either side of t=2.5 will cut your work in half.
h(2) = h(3)
h(1) = h(4) . . . for example
2) use Horner form to make manual evaluation easier.
h = (-5t +25)t +2 or = (5 -t)(5t) +2

what is 7 1/2 divided by 2 1/4 equeal
Answer:
Mixed number: 3 1/3
Improper fraction: 10/3
Step-by-step explanation:
Answer:
3 1/3 or 10 / 3
Step-by-step explanation:
7 1/2 divided by 2 1/4 =
Multiply 7 by 2.
7 x 2 = 14
Add 1 to 14 because of the 1 in 1/2.
14 + 1 = 15
7 1/2 turns into 15 / 2.
Do the same for 2 1/4.
Multiply 2 by 4.
2 x 4 = 8
Add 1 to 8 because of the 1 in 1/4.
8 + 1 = 9
2 1/4 turns into 9 / 4.
15 / 2 divided by 9 / 4
KEEP CHANGE FLIP!!
15 / 2 x 4 / 9
15 x 4 = 60 & 2 x 9 = 18
15 / 2 x 4 / 9 = 60 / 18
Let's simplify 60 / 18 by dividing by the greatest common factor; 6.
60 / 6 = 10 & 18 / 6 = 3
10 / 3 = 3 1/3
Hope this helped!

Answer:
The idea behind correct deciphering of word problems is correct understanding of the words used in the question. Both literally and mathematically. “More than” implies that something is greater than something in a literal sense. In mathematics, “a” is “more than” “b”, would be written as a>ba>b. Here even the verb, “is” plays an important role in the formation of the mathematical expression. For example, “a is more than b” means a>ba>b and “a more than b” means a+ba+b.
