Base and height of triangle whose height is four more than seven times its base. Whats the base and height? Thanks :) ...?

1 answer:

4 0

Assuming B is for Base and H is for Height of the triangle. The statement "Height is four more than seven times its base" indicates to us that the base is the variable.
So we'll have B = x, then we can arrive at the value of H which is 7x + 4.

A car's speedometer has a percent error of 5%. The speedometer currently shows that the car is traveling at a speed of 60 mph.

Minchanka [31]

Answer:

The actual speed of the car is either 57 mph or 63 mph

Step-by-step explanation:

Given as :

The measured speed o the car = 60 mph

The percentage error in speedometer = 5 %

Let The actual speed of car = x mph

Now, percentage error = $\dfrac{\textrm actual value - \textrm measured value}{\textrm measured value}$ × 100

So, $\frac{5}{100}$ = $\frac{x - 60}{60}$

or, $\frac{5}{100}$ × 60 = x - 60

Or, 3 = x - 60

∴ x = 63 mph

Hence The actual speed of the car is either 57 mph or 63 mph . Answer
