A bicycle store installs about 400 tires per day. Tires are installed Monday through Friday for 8 hours per day. The owner of th
dalvyx [7]
Dividing the number of tires that should be installed per day which  is 400 by the number of working hours which is 8 will give us 50 tires per hour. Assuming that the same mistake will take toll on the workers such that they will have 1 tire mistakenly installed in an hour, they will have 8 erroneous tires in a day. Multiplying this by 5 to make the answer per week will give 40. Out of the 400 x 5  = 2000 tires. The answer would be 2000 - 40 which is equal to 1940. The assumption must be valid.

a rectanglar solid has a base with lint 2 cm and width 8 cm. If the volume of the solid is 106 cm 3 to the highest, find the hei
Vanyuwa [196]
The hint says that volume of a rectangular solid = l*w*h, where l = length, w = width, and h = height. Use this to solve for the height of the solid by plugging in the numbers you know.

You know that length, l = 2cm, width, w = 8cm, and, *EDITED* volume = 160 cm^3. Plug these values into the equation for volume (the hint) and solve for h, the height:
Volume = lwh
160 = (2)(8)(h)
160 = 16h
h = 10cm

-------

Answer: The height is 10 cm

What is 20.00 multiplied by 20.00
Gala2k [10]

Answer:

400.00

Step-by-step explanation:

20*20 is close to 2*2. Since we have zeros, we can multiply 2 and 2 to get 4. Then we add two zeros because of the zero in 20 and the zero in the other 20. This could also be written as 20^{2} because we're multiplying 20 by itself.

An architect is designing an office building with n floors that will have an FM radio antenna 15.85 m tall on its roof. Each flo
sveticcg [70]

Answer:

h=3.9x+15.85 meters

Step-by-step explanation:

Let's say that the height of the floor just before the roof to the highest point of the roof is also 3.9 m, perhaps, we have an almost flat roof

Since the FM radio antenna is fixed on top of roof, the total height is that of previous floors and the antenna

Taking the building to have x number of floors with each floor having 3.9 m height, the function of height will be

h=3.9x + 15.85 meters
