Answer:
B
Step-by-step explanation:
First, you need to find out how many words she has left to type. 2/5 of 1000 is 400, so she has 600 words left to type. Now, you have all of the information you need.
Use pythagorean theorem;
a²+b²=c² where a and b are the legs and c is the hypotenuse of triangle
5²+b²=10²
b²=100-25
b²=75
b=√75
b=8.66 miles
Hope I helped :)
Answer:
√95 cm
Step-by-step explanation:
To solve, you need to use the pythagorean theorem, or a^2 + b^2 = c^2
The hypotenuse is the c and let one leg be b. You can write:
a^2 + 7^2 = 12^2
a^2 + 49 = 144
Now, you need to solve for a:
a^2 = 144 - 49
a^2 = 95
a = √95 cm, or about 9.75cm

Explanation:
The amount that Frank paid on his last credit card bill shows how piecewise functions work.
Taking into account that:
- 1.5 percent = 1.5/100 = 0.015,
- 1 percent = 1 / 100 = 0.01, and
- 0.015 × 500 = 7.50,
You can model the amount paid using the piecewise function p(x):
Thus, your calculation is:
- p(x) = $7.50 + $ 0.01 × (741.23 - 500) = $ 9.91
