Answer:
Round 34 down to 30 then round 39 up to 40
Step-by-step explanation:
34 ⟶ 30 34 is rounded down to 30
39 ⟶ 40 39 rounded up to 40
34 ⟶ 30
39 ⟶ 40
34 is rounded down to 30
39 rounded up to 40
Calculate mentally 34 × 39 = 1326
The estimated product is 1326.
Answer:
8 cups of potatoes are needed
Step-by-step explanation:
One way of doing this work is to write out
1/4 cup 1 cup
------------- , which is equivalent to ------------ (a unit rate)
1 bowl 4 bowl
and then multiply this unit rate by 32 bowls:
(1/4)(32 bowls) = 8 cups of potatoes are needed
I believe Qualitative Quantitative Discrete (Continuous is like 1/3 it's .33333333 and it goes on forever)
So $25 - $17.35 = $7.65
7.65÷ 17 = 45
45 = 45 min
Given:
There exist a proportional relationship between x and y.
To find:
The equation which represents a proportional relationship between x and y.
Solution:
If there exist a proportional relationship between x and y, then
where, k is constant of proportionality.
We know that, proportional relationship passes through the origin because (0,0) satisfy .
For x=0, check which equation has y=0.
In option A, .
In option B, .
In option C, .
In option D,
Only in option C, we have a equation of the form with 4 as constant of proportionality and it passes through (0,0).
Therefore, the correct option is C.
