Cole is finding the quotient of 78 ÷ 4. He creates this model to help him solve the division problem. 3 10-cube rods and 4 groups of 1 10-cube rod plus 2 unit cubes.
Which statements are true about Cole’s work? Check all that apply.

Cole’s model correctly shows that the quotient of 78 ÷ 4 is 12 with a remainder of 30.
Cole has not finished modeling this problem.
Cole needs to add another ten block to his model to show 78.
Cole should have divided the 3 extra tens blocks into 30 ones blocks.
A complete model would show the quotient of 78 ÷ 4 is 19 with a remainder of 2.

step-by-step explanation:

3100

step-by-step explanation:

55.44 inches

step-by-step explanation:

part a. assuming a perfectly linear relationship, we can find the slope from the first two data points.

slope = m = (change in rainfall)/(change in years)

= (61.80 -62.33)/(2005 -2004) = -0.53/1 = -0.53

then the point-slope form of the equation of the line can be written as

y = m(x -h) +k . . . . . m = -0.53, (h, k) = (0, 62.33)

y = -0.53x +62.33 . . . x = years after 2004

part b. in 2017, x = 2017 -2004 = 13. then the predicted rainfall is

y = -0.53·13 +62.33 = 55.44 . . inches

the predicted rainfall in 2017 is 55.44 in.

the answer is option a you would get more money.it would be $250.

step-by-step explanation:

for option b 200/2=100=50% 100/2=50=25% 50/5=10=5% it would be $220
