B) 25%
C) 33%
D) 50%

Answers

Answer 1
Answer: It is 33% because that is a third. A third of 150 is 50 and it has increased by 50 to get to 200.

Step-by-step explanation:

Two of the three sides of a triangle are 20 and 15. Which of the following numbers is not a possible perimeter of the triangle?a. 52
b. 57
c. 62
d. 67 e.72

Answers

Given:
1st side = 15
2nd side = 20
3rd side = ?

We will use a triangle inequality where the 3rd side is greater than the difference of the two sides and less than the sum of the two sides.

20 - 15 < x < 20 + 15
5 < x < 35

If x = 5 ; then the perimeter would be 5 + 15 + 20 = 40
if x = 35, then the perimeter would be 35 + 15 + 20 = 70

So the perimeter is within the range of 40 and 70.

Among the choices, E. 72 is outside the range. Therefore, it is not a possible perimeter of the triangle.

Susan volunteers at her local animal shelter. She counts the dogs and notices that there are a total of 37 dogs. Of those, 24 are female. What percentage of the dogs are male?

Answers

Answer:

35.135% of dogs are males ( approx )

Step-by-step explanation:

Given,

Total dogs = 37,

Also, dogs who are female = 24,

So, the male dogs = 37 - 24 = 13,

Hence, the percentage of male dogs = \frac{\text{Male dogs}}{\text{Total dogs}}* 100

=(13)/(37)* 100

=(1300)/(37)

=35.135\%

Kayla pays her plumber $22 per hour to replace her drain pipe. She ends up paying him $99. Which equation can you use to find h, the number of hours the plumber worked?

Answers

Simple....

so, if she payed him $99 in total and she payed him $22 dollars per hour...

just make it...

99=22h
and...

(99)/(22)= (22h)/(22)

4.5=h

Thus, the plumber worked 4.5 hours. (4 and a half hours)
Let's see... 
.
FORMULAS!! Or equations too...
.
Sorry, we just have to, even if you don't want to.
.
$22x = $99, where x is the numbers of hours the plumber worked.
.
Now this is REALLY easy.
.
Divide 22 on both sides!!
.
22x/22 = 99/22.
.
So... what's 99/22?
.
4.5.
.
The plumber worked 4.5 hours.

Hope I helped!!

A soup can in the shape of a right circular cylinder is to be made from two materials. The material for the side of the can costs $0.015 per square inch and the material for the lids costs $ 0.027 per square inch. Suppose that we desire to construct a can that has a volume of 16 cubic inches. What dimensions minimize the cost of the can? a. Draw a picture of the can and label its dimensions with appropriate variables.
b. Use your variables to determine expressions for the volume, surface area, and cost of the can.
c. Determine the total cost function as a function of a single variable. What is the domain on which you should consider this function?
d. Find the absolute minimum cost and the dimensions that produce this value.

Answers

Answer:

a) file annex

b) V(c) = π*x²*y

    A(x) = 2*π*x² + 32/x

    C(x) =  0,1695*x²  +  0,48 /x

     Domain C(x) = {x/ x >0}

d) C(min) = 0,64 $

    x = 1.123 in      radius of base

    y = 4,04 in      height of the can

     

Step-by-step explanation:

See annex file

Lets:

call x = radius of the base of the cylinder  and

y = the height of the cylinder

Then

Volume of the cylinder      ⇒    V(c) =  π*r²*h             ⇒V(c) = π*x²*y

And  y = V / ( π*x²)     ⇒   V = 16 / ( π*x²)

Area of cylinder  = lids area  +  lateral area

lids area = 2*π*x²  ⇒  lateral area = 2*π*x*y

lateral area =2*π*x [16/(π*x²) ]    ⇒   lateral area =  32/x

Then

A(x) = 2*π*x² + 32/x

Function cost C(x)

C(x) = 0.027 *  2*π*x²  +  0.015 * (32/x)

C(x) =  0,1695*x²  +  0,48 /x

Domain C(x) = {x/ x >0}

Now function cost:

C(x) =  0,1695*x²  +  0,48 /x

Taking derivative:

C´(x) =  2*0,1695*x  - 0.48/x²     C´(x)  =  0,339*x  -  0.48/x²

C´(x)  = 0            0.339*x³ - 0.48 = 0   x³ = 0.48/0.339   x³  = 1.42

x = 1.123 in

y = 16/πx²     ⇒  y = 4,04 in

C(min) = 0,64 $
