Answer:
The correct answer is Cruz's running speed is 10 miles per hour and his biking speed is 16 miles per hour.
Step-by-step explanation:
Let the speed of Cruz when running is s miles per hour and speed of cruz biking is 1.6s miles per hour.
Cruz ran for 90 minutes and rode is bike for 135 minutes.
Total distance covered by Cruz is 
× s + 1.6s × 
This distance is given to be 51 miles.
⇒ × s + 1.6s × = 51
⇒ 90s + 216s = 3060
⇒ 306s = 3060
⇒ s = 10
Cruz's running speed is 10 miles per hour and his biking speed is 16 miles per hour.
Answer:
A = pi units^2
or
A = 3.14 units^2
Step-by-step explanation:
The area of a circle is given by
A = pi r^2 where r is the radius
We are given a radius of 1
A =pi (1) ^2
A = pi*1 = pi
We can use pi = 3.14
A = 3.14 *1^2
A = 3.14
Answer:
16xy²(1 -3x)(4y +3)
Step-by-step explanation:
4x is a common factor of the terms of the first factor. Taking that out gives ...
4x(1 -3x)(16y³ +12y²)
Similarlly, 4y² is a common factor of the terms of the second factor. Taking that out gives ...
4x(1 -3x)(4y²)(4y +3)
Combining the two monomial factors, we have ...
16xy²(1 -3x)(4y +3)
The answer is B)-3
Hope this helps
