Answer:
t=2.25
Step-by-step explanation:
9 divided by 4 is 2.25
and 4 x 2.25 is 9
The product of 3.6 x 4.2 is 15.12
7/9 of 3/14 is 1/6.
Tell me if I'm wrong.
Hope this helps :)
Answer:
Which plant was taller when Nara got the plants? C. They were equally tall
Which plant grew faster? B. The second plant
Step-by-step explanation:
Slope of the first plant :
m = (y2 - y1)/(x2- x1)
m = (36 - 34)/(15 - 10) = 0.4
y-intercept of the first plant :
y = m*x + b
b = y1 - m*x1
b = 34 - 0.4*10 = 30
From the picture we can see that the y-intercept of the second plant is 30 cm
Y-intercept represents plant heights when Nara got the plants; then they were equally tall
From the picture we can see that second plant grew 2 cm in 2 days; then its slope is 2/2 = 1
Slope measures how fast each plant grew; then the second plant grew faster
17 x 15.56 = 15.56 x 17 demonstrates 3) Communitive Property of Multiplication. The Community property allows you to swap the numbers in multiplication and addition problems, like in this problem.
