3 1/4 - 2 1/3 what is the answer please explain

anastassius [24]

Answer:

it is 0.916 (the six is repeated. a line under a number means repeated in this case)

Step-by-step explanation:

First you take 3 1/4 and turn it into 13/4 and turn 2 1/3 into 7/3 and transform those into decimals 13/4 = 3.25 and 7/3 = 2.3 and subtract which is 0.95 plus the fact that the three is repeated which gets your answer of 0.916 however you should say that if they want you to simplify it to two/three decimals, it is 0.95 but if they want it exact it is 0.916 with the six being repeated

1. The position of a particle moving along a coordinate axis is given by: s(t) = t^2 - 5t + 1. a) Find the speed of the particle

zimovet [89]

Answer: $\left | 2t-5\right |,\ 2,\ 2t-5$

Step-by-step explanation:

Given

Position of the particle moving along the coordinate axis is given by

$s(t)=t^2-5t+1$

Speed of the particle is given by

$\Rightarrow v=\dfrac{ds}{dt}\\\\\Rightarrow v=\dfrac{d(t^2-5t+1)}{dt}\\\\\Rightarrow v=\left | 2t-5\right |$

Acceleration of the particle is

$\Rightarrow a=\dfrac{dv}{dt}\\\\\Rightarrow a=2$

velocity can be negative, but speed cannot

$\Rightarrow v=\dfrac{ds}{dt}\\\\\Rightarrow v=\dfrac{d(t^2-5t+1)}{dt}\\\\\Rightarrow v=2t-5$

Find the two points on segment AB that divide the segment into 3 congruent Parts if A has coordinates (0 0) and point B has coor

Elena L [17]

Answer:

(3, 2), (6, 4)

Step-by-step explanation:

Since one end (A) of the segment AB is at the origin, the required points will be 1/3 and 2/3 of the coordinates of B:

(1/3)(9, 6) = (3, 2)

(2/3)(9, 6) = (6, 4)

the ratio of boys to girls at the beach clean up was 7:8 if there are 42 boys how many girls are there

Len [333]

48 girls are there. Given that there is a ratio of boys to girls of 7:8. Then divide 42 boys by 7 boys which equals 6. After, multiply 6 by 8 girls equals 48 girls.
