James bakes 12 cookies in 15 minutes. How many cookies will he bake in 60 minutes?

48 :D

Step-by-step explanation:

James will bake 48 cookies.

Step-by-step explanation:

We know that James can bake 12 cookies in 15 minutes. So, we can multiply both amounts ( the amount of cookies and the minutes it takes) to solve this question. First, ask " How many 15 minutes are in 60 minutes?" Or, 15 multiplied by what makes 60? The answer to this is 4. 15 minutes x 4= 60 minutes. Now, all we have to do is multiply the other side by the same amount. 12 cookies x 4 =48 cookies. So, he bakes 48 cookies.

23°

Step-by-step explanation:

Point V is the point of intersection of the diagonals of the parallelogram. The opposite sides of a parallelogram are equal. The diagonals of a parallelogram bisect each other, also the diagonal of a parallelogram separates it into two congruent triangles.

m∠TSV + m∠SVT + m∠VTS = 180° (sum of angles in a triangle)

31 + 126 + m∠VTS = 180

157 + m∠VTS = 180

m∠VTS = 180 - 157

m∠VTS = 23°

ΔVTS = ΔVRU (diagonal of a parallelogram separates it into two congruent triangles)

Therefore ∠URV = ∠VTS = 23°
