The sum of two numbers is 52 . The larger number is 2 less than twice the smaller number .What are the numbers
Answers
Answer:
35.34 and 16.66
Step-by-step explanation:
Given data
let the numbers be x and y
the smaller number = x
the larger number = y
x+y=52--------1
The larger number is 2 less than twice the smaller number
y=2x-2-------2
put y= 2x-2 in eqn 1
x+2x-2=52
3x-2=52
3x=52-2
3x=50
x= 50/3
x= 16.66
put x=16.66 in eqn 1 to find y
x+y=52
16.66+y= 52
y=52-16.66
y= 35.34
Hence the numbers are
35.34 and 16.66
Check
35.34+16.66= 52

Then, the triangle is a
c. neither a 45-45-90 triangle nor a 30-60-90 triangle.
Looking at the lengths, if the triangle is a right triangle
2 and 1 must be the measure of the legs
2√3, the measure of the hypotenuse
If we use the Pythagorean theorem,
2^2 + 1^2 = (2√3)^2
5 = 12 (not correct)
Therefore, the triangle is not a right trangle

- Isabel reads 24 chapters of a book in 8 hours.
ToFind:
- What is the rate in chapters per hour?
Step-wise-StepExplanation:
Considering that Isabel reads the book at a constant rate or we can say that no. of books she read is same for all the 8 hours.
⇒ In 8 hours = 24 chapters
⇒ In 1 hour = 24 / 8 chapters
⇒ In 1 hour = 3 chapters
That means, Isabel reads 3 chapters per hour with the same pace. The Question can be simply solved by using Unitary method
Answer:
the unit rate, in chapters per hour, would be how many chapters in one hour --- but, for 23 chapters/78 hours = this fraction (23/78) is already in simplified (i.e., reduced) form --- i.e., 23 is prime, and 78 = 2(39) = 2(3)13, so 23 and 78 contain no factors in common --- so, the unit rate would be (23/78) chapters per hour --- if the problem had been, for example, 23 chapters in 69 hours, then the unit rate would have been (23/69) chapters per hour = (1/3) chapters per hour, or one chapter every 3 hours (though this is not a unit rate)

Answer:
A production level that will minimize the average cost of making x items is x=5.
Step-by-step explanation:
Given that
is the cost of manufacturing x items
To find a production level that will minimize the average cost of making x items:
The average cost per item is
Now we get
f(x) is continuously differentiable for all x
Here x≥0 since it represents the number of items.,
Put x=0 in
For x=0 the average cost becomes 13000
∴ f(0)=13000
To find Local extrema :
Differentiating f(x) with respect to x
∴ x=5 gives the minimum average cost .
At x=5 the average cost is
∴ f(5)=12825 which is smaller than for x=0 is 13000
∴ f(x) is decreasing between 0 and 5 and it is increasing after 5.
