The average number of pages she reads per hour is 19 pages per hour
<h3>How to determine the average number of pages she read per hour?</h3>
The given parameters are:
Number of pages = 76 pages
Number of hours = 4 hours
The average number of pages she reads per hour is calculated using the following formula
Average = Number of pages/Number of hours
Substitute the known values in the above equation
Average = 76 pages/4 hours
Evaluate the quotient
Average = 19 pages per hours
Hence, the average number of pages she reads per hour is 19 pages per hours

This the 2 one i hope it's right
I(interest)=P(princple)R(rate)T(time)
I=420*.07*1=$29.4
A is correct.
Peace.
Answer:
405
Step-by-step explanation:
First you do the exponent first which would be 3 to the power of 4 which is 81 and then you would multiply that by 5 which gives you 405.
The given triangle is a right-angled triangle. This means that special trig identities can be applies
<u>These identities are as follows:</u>
sin (theta) = opposite / hypotenuse
cos (theta) = adjacent / hypotenuse
tan (theta) = opposite / adjacent
<u>Now, for the unknown theta in the triangle:</u>
The opposite side is 16 and the hypotenuse is 20
This means that we will use the <u>sin</u> not the cos as Bob did
<u>The solution will be as follows:</u>
sin (theta) = opposite / hypotenuse
sin (theta) = 16 / 20
theta = sin^-1(16/20)
theta = 53.13°
Hope this helps :)
