Step-by-step explanation:
25/100*Y = 21
100/25 * 25y/100 =21 *100/25
y = 2100/25
y = 84
Steps:
25% of blank is 21
Of means multiply
Is means equals
To change a percent to a decimal move the decimal place tow spots to the left
25% of blank is 21
25% * x = 21
0.25 * x = 21
x = 21 / 0.25
x = 84
Check:
0.25 * x = 21
0.25 * 84 = 21
21 = 21 ✅

2x + 8 = -4 solve for c
Show work please
Answers
Answer: x=-6
Step-by-step explanation:
Given
2x + 8 = -4
Subtract 8 on both sides
2x + 8 - 8 = -4 - 8
2x = -12
Divide 2 on both sides
2x / 2 = -12 / 2
x = -6
NOTE: I assume the questions "solve for c" actually means "solve for x"

Since we know that the sum of the two angles equal 180, we can add them together to equal 180 degrees.
2x+10+x+26=180
Combine like terms.
3x+36=180
Subtract 36 from both sides.

Suppose that in the inventory problem, the storage cost depends on the maximum inventory size, rather than the average. This would be more realistic if, for example, the company had to build a warehouse large enough to hold the maxi- mum inventory, and the cost of storage was the same no matter how full or empty the warehouse was. Show that in this case the number of units that should be ordered or manufactured to minimize the total cost is q= âfM/k

pdf Ron, Sue, and Ted arrive at the beginning of a professor’s office hours. The amount of time they will stay is exponentially distributed with means 1, 1/2, and 1/3 hours. (a) What is the expected time until only one student remains? (b) For each student, find the probability they are the last student left. (c) What is the expected time until all three students are gone?
Answers
Answer:
a) 0.45 hours
b)
P( Ron ) = 7/12
P( sue ) = 4/15
P(Ted ) = 3/20
c) 1.22 hours
Step-by-step explanation:
Ron , sue and Ted
mean values = 1, 1/2 , 1/3 hours
a) determine the expected time until only one student remains
E(x) = 9/20 = 0.45 hours
b) Probability that each student is the last student left
P( Ron ) = 7/12
P( sue ) = 4/15
P(Ted ) = 3/20
C) Time until all students are gone
= 146 / 120 = 1.22 hours
attached below is the detailed solution
This question is based on the concept of probability.Therefore, the answers are as follows:
(a) 0.45 hours
[tex]\bold{(b) \, P(Ron) = \dfrac{7}{12} ,P (Sue) = \dfrac{4}{15} ,P(Ted) = \dfrac{3}{20}\beta}[/tex]
(c) 1.22 hours
Given:
The amount of time they will stay is exponentially distributed with means 1, 1/2, and 1/3 hours.
According to the question,
The amount of time they will stay is exponentially distributed with means 1, 1/2, and 1/3 hours.
(a) The expected time until only one student remains,
[tex]E(X) = \dfrac{9}{20} = 0.45 \,hours[/tex]
(b) Now, find the probability they are the last student left,
[tex]P(Ron) = \dfrac{7}{12} \\P (Sue) = \dfrac{4}{15} \\P(Ted) = \dfrac{3}{20}[/tex]
(c) The expected time until all three students are gone is,
[tex]= \dfrac{146}{120} \\\\= 1.22 hours[/tex]
Therefore, the answers are as follows:
(a) 0.45 hours
[tex](b) P(Ron) = \dfrac{7}{12} ,P (Sue) = \dfrac{4}{15} ,P(Ted) = \dfrac{3}{20}\beta[/tex]
(c) 1.22 hours

Find y
To find y, we make use of the relationship between sides lengths 44 & y and angle 39
The relationship is:
[tex]cos(39) = \frac{44}{y}[/tex]
i.e.
[tex]cos(\theta) = \frac{Adjacent}{Hypotenuse}[/tex]
Make y the subject
[tex]y = \frac{44}{cos(39)}[/tex]
