An engineer performs a flow test of a cooling water system. There are 32 flow elements. For each flow element she needs two 3 fe

et lengths of poly flow tubing with quick release connectors on each end. Both lengths of poly flow tubing plug into a test gauge to measure the flow across each flow element. Each test gauge is $80. The 3/16” polyflow tubing is $6.00 for 100 ft. The connectors are $2.50 each. The budget for the test is $3,000.00. After buying the necessary equipment, how much under budget should she be?

Can someone please help me with this problem!

Answer:

11 yards

Step-by-step explanation:

The volume of a cone formula is:

V=\frac{1}{3}\pi r^2 h

Where V is the volume,

r is the radius (half of diameter)

h is the height

Given,

h = 15

V = 475.17

We find the radius (r) first by substituting given values:

V=\frac{1}{3}\pi r^2 h\\475.17=\frac{1}{3}\pi r^2 (15)\\475.17=5\pi r^2\\r^2=30.25\\r=5.5

The radius (r) is 5.5 yards

We need the diameter, which is DOUBLE THE RADIUS, so diameter would be:

Diameter = 5.5 * 2 = 11 yards

In order to compare the real estate markets in Pittsburgh and Philadelphia, a realtor selected
melisa1 [442]

Answer:

The price of the homes in the Pittsburgh sample typically vary by about $267,210 from the mean home price of $500,000.

Step-by-step explanation:

The dotplots reveal that the variability of home prices in the Pittsburgh sample is greater than the variability of home prices in the Philadelphia sample. Therefore, the standard deviation of the home prices for the Pittsburgh sample is $267,210 rather than $100,740. The correct interpretation of this statistic is that the price of homes in Pittsburgh typically vary by about $267,210 from the mean home price of $500,000.

The diagram of a rectangular canvas is 4 1/2 by 2 if the paint to cover the canvas costs 4.50 what is the price per square foot
kirill115 [55]

Answer:

The price per square foot is $0.50

Step-by-step explanation:

step 1

Find the area of the canvas

The area of the rectangular canvas is equal to

A=LW

we have

L=4\frac{1}{2}\ ft= 4+\frac{1}{2}=\frac{4*2+1}{2}=\frac{9}{2}\ ft

W=2\ ft

substitute

A=(\frac{9}{2})(2)=9\ ft^2

step 2

Find the price per square foot

Divide the cost by the area

so

\frac{4.50}{9}=\$0.50\ per\ square\ foot
