A plane travels at a speed of 205mph in still air. Flying with a tailwind, the plane is clocked over a distance of 975 miles. Flying against a headwind, it takes 2 hours longer to complete the return trip. What was the wind velocity?
no links
Answers
Answer:
T1 = 975 / (205 + V) flying with wind
T2 = 975 / (205 - V) flying against wind
T2 = T1 + 2
975 * {1 / (205 - V) - 1 / (205 + V)] = 2
(205 + V + V -205) / (205^2 - V^2) = 2 / 975
V^2 + 975 V - 42025 = 0 rearranging
V = 41.3
Values of flying are 246.3 and 163.7
Check:
T1 = 975 / 246.3 = 3.96 hrs
T2 = 975 / 163.7 = 5.96 hrs

A lab orders a number of chemicals from the same supplier every 10 days. The lead time is six days. The manager of the lab must determine how much of one of these chemicals to order. Check of stock reviewed that 9 25-milliliter (ml) jars are on hand. Daily usage of the chemical is appropriately normal with a mean of 16 ml per day and a standard deviation of 3.5 ml per day. The desired service level for this chemical is 95%. a) How many jars of the chemical should he ordered
Answers
Answer:
3 jars of the chemical should be ordered
Step-by-step explanation:
Given the data in the question;
Ol = 10 days
d = 16 ml
z = 1.65 at 95% service level
σ = 3.5 ml
Check of stock reviewed that 9 of 25-milliliter (ml) jars are on hand
so inventory in position = 9 × 25 = 225 ml
now,
since this is a fixed-order-internal system;
first we determine our Target inventory
Target inventory = 16 × ( 10 + 6) + 1.65√( 10 + 6 ) × 3.5
Target inventory = 265 + 23.1
Target inventory = 288.1
so
Amount to order = Target inventory - inventory in position
Amount to order = 288.1 - 225 = 63.1 ml
∴ number of jars to order will be;
⇒ 63.1 ml/ 25 ml = 2.5 { approximately 3 jars }
Therefore, 3 jars of the chemical should be ordered
Solve for x.
3/4(8x-12)=2(4x+1)-4
What are the step to this equation.
Answers
Combine like terms:
3/4(8x-12)=2(4x+1)-4
6x-9=2(4x+1)-4
6x-9=8 x-2
2. Group all X terms on the left side of the equation
Subtract 8X from both sides:
6x-9=8 x-2
(6x-9)-8x=(8x-2)-8x
-2x-9=(8x-2)-8x
-2x-9=-2
Group all constants on the right side of the equation
Add 9 to both sides of the equation:
-2x-9=-2
(-2x-9)+9=-2+9
-2x=-2+9
-2x=7
Isolate the X
Divide both sides of the equation by -2:
-2x=7
(-2x) 7
——- = —
-2 -2
X= 7

X= -7

You take 1,000 because it's in the thousandths place of 1,255. The value of that one is 1,000 so you multiply that times 100, which is the value of 1 in 82,175.

The following is a parallelogram. What is the measure of angle N?
Answers
Answer:120 Degrees
Step-by-step explanation:
Angle M and N add up to 180 degrees so,
180= 11x-40 (Since 3x+8x would be 11x)
220=11x (Add 40 to both sides)
X=20 (divided 220 by 11)

A car manufacturer has two production plants in different cities. Every day, plant A produces 120 of a certain

Mrs. Crosland asked students to factor the expression 28x - 8. The students offered the answers shown in the box. Which student(s) offered answer(s) equivalent to the original expression? A. only Danny B. only Irene C. both Carlos and Danny D. both Carlos and Irene
Answers
Answer:
Step-by-step explanation:
I can't see the factorisation that the students did. That is, Danny, Carlos and Irene. You either forgot to upload, or you couldn't.
However, I will factorise the expression for you, while you check you book to know who did the exact same factorisation.
28x - 8
This equation can be factorised when divided by 2, into
2(14x - 4)
At the same time, it can be factorised when divided by 4, into
4(7x - 2)
Basically, either of the students who choose between 2(14x - 4) and 4(7x - 2) is/are whom you'd pick for your answer.
