If a person walks 1/2 mile in 1/4 hour, how far does that person walk in 1 3/4 hours at that rate?
1 answer:
Answer:
3 1/2 miles
Step-by-step explanation:
We can use a ratio to solve
1/2 mile x miles
----------------= ---------------
1/4 hour 1 3/4 hours
Changing to improper fractions
1/2 mile x miles
----------------= ---------------
1/4 hour 7/4 hours
Using cross products
1/2 * 7/4 = 1/4x
7/8 = 1/4x
Multiply each side by 4
7/2 = x
Changing back to a mixed number
3 1/2 =x

Answer:
alternate angle and counter
F(x)=x^2+bx-16
x=5
F(5)=5^2+b(5)-16
=25+5b-16=0
=5b+9=0
=5b=-9
=b= -9/5
By remainder theorem
Answer:
f(3) = 22
Step-by-step explanation:
f(x) = 2x^2 + 4, find f(3)
f(3) = 2(3)^2 + 4
f(3) = 2 (9) + 4
f(3) = 18 + 4
f(3) = 22
