Answer:
y=10
Step-by-step explanation:
[tex]\frac{4}{100}[/tex]=[tex]\frac{y}{250}[/tex]
cross-multiply, 4*250=100y
isolate the variable and solve for y, 1000=100y
divide 100 on both sides, 10=y
The sum of two numbers is 52 and the difference is 8. What are the numbers?
Answer:
22, 30
Step-by-step explanation:
52/2=26
26-4=22
26+4=30
30+22=52
Answer:
30 and 22
Step-by-step explanation:
This can be solved using system of equations
Let x = the bigger number
Let y = the smaller number
The sum of two numbers is 52
x + y = 52
The difference is 8
x - y = 8
x + y = 52
x - y = 8
I will solve using elimination
(x + y = 52)
+ (x - y = 8)
-----------------------
2x = 60
/2 /2
x = 30
x + y = 52
30 + y = 52
-30 -30
y = 22

What Kind of Math is this?
A waiter determines his salary for a week using the formula S = 3.75h + t, where S is his salary, h is the number of hours he works, and t is his total tips. How much does the waiter make if he works 30 hours in a week and makes a total of $538.75 in tips?
Answer:
$651.25
Step-by-step explanation:
plug your variables into your equation so,
S= 3.75(30)+ 538.75
and solve
S=112.5+538.75
S=651.25
Answer:
$651.25
Step-by-step explanation:
S = 3.75h + t
Given:
h = 30
t = 538.75
Work:
S = 3.75h + t
S = 3.75(30) + 538.75
S = 112.5 + 538.75
S = 651.25

a company staff consists of 20 accountants, 12 economists and 4 secretaries. a staff is chosen at random. Find the probability that the staff is an accountant. With solution.
Answer:
5/9
Step-by-step explanation:
Number of accountants = 20
Number of economists = 12
Number of secretaries = 4
Total number of Staffs = 20 + 12 + 4 = 36 staffs
Probability = required outcome / Total possible outcomes
Required outcome = number of accountants
Total possible outcomes = total number of staffs
P(selecting an economist) = 20 / 36 = 5 / 9
The probability that the staff is an accountant is 5/9.
Given
A company staff consists of 20 accountants, 12 economists and 4 secretaries. a staff is chosen at random.
Probability;Probability is defined as the number of observations and total number of observation.
Total number of Staffs = 20 + 12 + 4 = 36 staffs.
The following formula is used to determine the probability;
[tex]\rm Probability=\dfrac{Accountant \ staff}{Total \ number \ of \ staff}[/tex]
Substitute all the values in the formula;
[tex]\rm Probability=\dfrac{Accountant \ staff}{Total \ number \ of \ staff}\\\\\rm Probability=\dfrac{20}{36}\\\\\rm Probability=\dfrac{5}{9}[/tex]
Hence, the probability that the staff is an accountant is 5/9.

The depth of a river changes after a heavy rainstorm, Its depth, in feet, is modeled as a function of time, in hours. Consider this graph of the function. Enter the average rate of change for the depth of the river, measured as feet per hour, between hour 9 and hour 18. Round your answer to the nearest tenth
Answer:
The average rate of change for the depth of the river measured as feet per hour is approximately 0.3 feet/hour
Step-by-step explanation:
The depth of the river in feet with time is given by the function with the attached
From the graph, we have;
The depth of the river at hour t = 9 is f(9) = 18 feet
The depth of the river at hour t = 18 is f(18) = 21 feet
The average rate of change, A(x), for the depth of the river measured as feet per hour is given as follows;
[tex]A(X) = \dfrac{f(b) - f(a)}{b - a}[/tex]
Therefore, for the river, we have;
[tex]A(X) = \dfrac{f(18) - f(9)}{18 - 9} = \dfrac{21 - 18}{18 -9} = \dfrac{3}{9} =\dfrac{1}{3}[/tex]
The average rate of change for the depth of the river measured as feet per hour A(X) = 1/3 feet/hour
By rounding the answer to the nearest tenth, we have;
A(X) = 0.3 feet/hour.
Express as a trinomial.

3a=−6
Step 2: Divide both sides by 3.
3a/ 3 = −6/ 3
a=−2
A coffee shop recently sold 8 drinks, including 2 Americanos. Considering this data, how many of the next 20 drinks sold would you expect to be Americanos?
Answer:
5 drinks will be americanos
Step-by-step explanation:
2:8 (2/8)
simplify
1:4 (1/4)
divide 20 by 4
5:20
The number of next 20 drinks which may be Americanos is 5.
What is Probability?Probability is simply the possibility of getting an event. Or in other words, we are predicting the chance of getting an event.
The value of probability will be always in the range from 0 to 1.
Given that,
Total drinks sold = 8
Number of drinks that is Americanos = 2
Probability of finding Americano = 2/8 = 1/4
If the total number of drinks next is 20,
Number of Americanos expected = Probability of Americanos × Number of drinks
= 1/4 × 20
= 5
Hence the number of Americanos expected is 5.
