Kelvin would read 70 pages in 2 hours.

Step-by-step explanation:

Total pages read per hour by Kevin= 35 pages

Total number of hours in consideration= 2 hours

Hence total pages that are read by Kevin in 2 hours= Pages read in 1 hour * Total hours in consideration

Substituting the values of pages read by Kevin in 1 hour and total hours in consideration

Total number of pages= 35*2= 70 pages

Hence, the total number of pages read by Kevin in 2 hours is 70 pages

Hey fellas, giving brainliest and a lot of points to who gets this correct

Ainat [17]

Answer:

$7\frac{1}{12}$ or $\frac{85}{12}$

Step-by-step explanation:

total boxes = Jills boxes + Mikes boxes

total boxes = $5\frac{1}{3} +1\frac{3}{4}$

= $\frac{16}{3} + \frac{7}{4}$

= $\frac{64+21}{12}$

= $\frac{85}{12}$

= $7\frac{1}{12}$

The equation r(t)= (2t)i + (2t-16t^2)j is the position of a particle in space at time t. Find the angle between the velocity and

ankoles [38]

Answer:

The answer is 135 degrees.

Step-by-step explanation:

As we are given the position. If we take the derivative, we get the velocity vector. If we take the derivative again, we find the acceleration vector of the particle.

$r(t)=(2t)i+(2t-16t^{2})j$

$V(t)=2i+(2-32t)j$

$a(t)=-32j$

At time t=0;

$v(t)=2i+2j$

$a(t)=-32j$

As i attach in the picture the angle between the velocity and acceleration vector is $(45+90)=135$ degrees
