Answer:
Mrs. Stewart paid $86.25 for all the books.
Step-by-step explanation:
With the information provided, you have to add the result of multiplying the nine books for its price plus the remaining books for the price per book. To find the number of the remaining books you can substract the nine books from the total amount Mrs. Stewart purchased.
Cost=(9*4.95)+((15-9)*6.95)
Cost=44.55+41.7
Cost=86.25
According to this, the answer is that Mrs. Stewart paid $86.25 for all the books.
Answers:
∠A=45° & ∠B=45°
Step-by-step explanation:
In triangle ABC, all angles are less than 180° but their sum is 180°
For the trigonometric statements
sin(A)=cos(B)
sin(B)=cos(A)
These are true when these angles that are A and B are equal and on these angles the sin and cos value must be same.
Hence, both angles are of 45°
well, we know that there are 1.609 kilometers in 1 mile, so 58 kilometers will be 58 ÷ 1.609 ≈ 36.05 miles.
we know the car is doing 36.05 miles in 1 hour, how long will it be for 32 miles?
