The length of a rectangle is 9 centimeters more than half

Mathematics

Sedaia [141]3 years ago

Answer:

l = 16 cm

Step-by-step explanation:

Let's set the width of the rectangle as "w" and the length of the rectangle as "w/2 + 9".

The perimeter of a rectangle is calculated by adding up the value of all of its side lengths. Therefore, we can find the perimeter using 2l + 2w = P.

We can substitute 60 for P and w/2 + 9 for l.

  • 2(w/2 + 9) + 2w = 60
  • 2w/2 + 18 + 2w = 60
  • w + 18 + 2w = 60
  • 3w + 18 = 60
  • 3w = 42
  • w = 14

Substitute w = 14 into the equation for length l.

  • l = w/2 + 9
  • l = 14/2 + 9
  • l = 16

The length of the rectangle is 16 cm.

A shop sells newspapers for a profit of 0.5%. His sales for the month of January were $8341.50. How much of this is profit?
Doss [256]
Amount of sales  of newspapers for the month of January = $8341.50
Percentage of profit for which the newspaper is sold = 0.5%
Then
Amount of profit made in the month of January = 0.5% * 8341.50 dollars
                                                                           = (0.5/100) * 8341.50 dollars
                                                                           = 4170.75/100 dollars
                                                                           = 41.707 dollars
                                                                           = 41.71 dollars
So the shop makes a profit of $41.71 in the month of January by selling newspapers worth $8341.50. I hope the procedure is perfectly clear for you to understand.

determine the area under the standard normal curve that lies to the left of (a) z=0.92 (b) z=-1.26 (c) z= -0.64 (d) z= -1.09
enot [183]

Your main choices here are (1) a calculator with statistical functions and (2) a table of z-scores.


(a) On my TI-83 Plus calculator I typed in normcdf(-1000, 0.92). The calculator returned the value 0.821. This is approx. 8/10 of the total area under the std normal curve.


(b) I typed in normcdf(-1000, -1.26) and got 0.104


(c) I typed in normcdf(-1000, -0.64) and got 0.261


(d) I typed in normcdf(-1000, -1.09) and got 0.138
