Part A: The table does not represent y as a function of x. We can not input 1 and get 4 and 2 as outputs ( or input 3 and get 12 and 6 as outputs ).
Part B : f (120) is a cost for renting a peddleboat for 120 hours;
f (120) = 20 + 10 * 120 = 20 + 1,200 = 1,220.
Answer:
B. 29.5
Step-by-step explanation:
Cos=A/H
=12/x
x=12/cos66
Answer:
200
Step-by-step explanation:
1. 4 times 5 because there are 5 types in total and they make 4 of each type in each batch they bake. 4*5 is 20.
2. 20 times 10 because they make 10 batches and you know there are 20 in each batch. so 20 times 10 is 200.
200 is the answer.
Answer:
46 logs on the 5th row.
Step-by-step explanation:
Number of logs on the nth row is
n = 50 - (n-1)
n = 51 - n (so on the first row we have 51 - 1 = 50 logs).
So on the 5th row we have 51 - 5 = 46 logs.
Answer:
The minimum number of freezer bags needed to store all the blueberries is 7
Step-by-step explanation:
we know that
To find out the number of freezer bags needed , divide the total pounds of blueberries by 3 3/4, but first convert mixed number to an improper fraction
![23\frac{1}{2}\ lb=\frac{23*2+1}{2}=\frac{47}{2}\ lb](https://tex.z-dn.net/?f=23%5Cfrac%7B1%7D%7B2%7D%5C%20lb%3D%5Cfrac%7B23%2A2%2B1%7D%7B2%7D%3D%5Cfrac%7B47%7D%7B2%7D%5C%20lb)
![3\frac{3}{4}\ lb=\frac{3*4+3}{4}=\frac{15}{4}\ lb](https://tex.z-dn.net/?f=3%5Cfrac%7B3%7D%7B4%7D%5C%20lb%3D%5Cfrac%7B3%2A4%2B3%7D%7B4%7D%3D%5Cfrac%7B15%7D%7B4%7D%5C%20lb)
![\frac{47}{2}:\frac{15}{4}=\frac{47*4}{2*15} =\frac{94}{15}=6.3\ bags](https://tex.z-dn.net/?f=%5Cfrac%7B47%7D%7B2%7D%3A%5Cfrac%7B15%7D%7B4%7D%3D%5Cfrac%7B47%2A4%7D%7B2%2A15%7D%20%3D%5Cfrac%7B94%7D%7B15%7D%3D6.3%5C%20bags)
Round up
7 bags
therefore
The minimum number of freezer bags needed to store all the blueberries is 7
