Answer:
7 miles
Step-by-step explanation:
Distance = Rate times Time
Distance #1: (15 mph)(12/60 hr) = 3 miles
Distance #2: (12 mph)(20/60 hr) = 4 miles
Total distance ridden = 7 miles
Answer:
17-i
--------
29
Step-by-step explanation:
To simply fractions with complex numbers, we have to multiply by the complex conjugate of the denominator.
The denominator is 5+2i, so the complex conjuate is 5-2i
3+i 5-2i
------ * ---------------
5+2i 5-2i
Simplifying the numerator
(3+i) * (5-2i) = 3*5 + 5i -3*2i -2i^2 = 15 +5i -6i -2(-1) = 15-i+2 = 17-i
Simplifying the denominator
(5+2i) (5-2i) = 25 -10i + 10i -4i^2 = 25 -4(-1) = 29
17-i
--------
29
I’m not 100% sure but my best guess would be
6.A
7.A
8.C
9.C
10.D
First, we see a rectangle shape with little squares in it. The length is 5 and the width is 4. If we multiply them, we get 20 square units. However, we will use the 20 to solve the question. Also, we see that there are only 3 squares.
3/20
Let's divide the fraction. 3 / 20 is 0.15. We result with 0.15. Now, we multiply the decimal by 100 to get a percent; we are converting from decimal to percent. As a result, we get 15% as our answer.
3/20 = 0.15 x 100 = 15%
