Answer:
(1) 820
(2) 1920
Step-by-step explanation:
(1) solving 20 x 41, using associative property.
20 * 41 = (2 x 10) x 41 = 2 x (10 x 41)
= 20 x 41 = 2 x 410
= 820 = 820
(2) distribute 32 as 30 + 2 and solve.
60 x 32
= 60 x (30 + 2) = 60(30) + 60(2)
= 1800 + 120
= 1920

Answer:
3 people
Step-by-step explanation:
Reading a stem & leaf plot can be hard!
Remember in the middle or whichever side is single digits divided by the line is your tens place values.
The 2 has two values on the other side, giving us 23 & 29 laps.
The 1 has one value on the other side, giving us 11 laps.
The 0 has no other value, so there is no data for that row.
There were 3 data points below 30, & these were 11, 23, & 29.
Hope this helped. :)
29.) This is simply interpreting the linear function.
The function:
96+2.1x
a.) The 96 is what you start with from the beginning. So, we know Rachel weighed 96 ounces when she was born.
b.) Again, interpretation. The 2.1 is the slope, or the change in the line. So we know that Rachel gains 2.1 ounces each day.
30.) For this one, you just have to plug 9 into the equation for x.
