( I NEED THIS FAST)A speedometer has a percent error of 10%. The actual speed of the car is 40 mph. Select from the drop-down me

ikadub [295]

Answer = 36.0 mph

As per the question,

Actual speed of the car = 40 mph.

Speedometer has a percent error of 10%.

The error can be negative as well as positive.

If the error is negative, it means speedometer is showing less speed than actual speed= - 10%

10 % of 40 = 4

speed shown by speedometer = 40 - (10% of 40) = 36 mph

If the error is positive, it means speedometer is showing more speed than actual speed = +10%

speed shown by speedometer = 40 + ( 10% of 40) = 44 mph

as per the given options, correct option is 36.0 mph

A technician is installing two bundles of cables for an online system. Bundle A is 1

Mila [183]

Answer:

Answer D: 8.7 cm

Step-by-step explanation:

First compare the actual diameters of both cables to find out which one is larger. If we write both diameters in fraction form (as they are given), we need to have them expressed with the same denominator for a straight forward comparison:

Bundle A: $1\frac{3}{8} =1+\frac{3}{8} = \frac{8}{8} +\frac{3}{8} =\frac{11}{8}$

Bundle B: $2\frac{3}{4} =2+\frac{3}{4}=\frac{8}{4} +\frac{3}{4}=\frac{11}{4}$

So we multiply this last fraction by 2 in numerator and denominator to obtain the same denominator as for Bundle A without actually changing its numerical value: $\frac{11}{4} = \frac{22}{8}$

So now we compare Bundle A with bundle B, and see that bundle B has the larger diameter: 22/8 inches

The hole has to be 25% larger than this larger diameter, so we estimate 25% of 22/8 in is:

$\frac{22}{8} * \frac{25}{100} = 0.6875$ inches

Therefore, the hole must be of diameter 22/8 in plus 0.6875 in = 3.4375 in

Now we convert this value into centimeters by multiplying it by 2.54 (since one inch is 2.54 cm):

3.4375 * 2.54 = 8.73125 cm

which rounded to the nearest tenth as requested in the problem is: 8.7 cm
