Answer:
x=65°
Step-by-step explanation:
Full circle is 360°,then 360-90-180=90,and
x+25=90
x=90-25
x=65°
Given that Noemi makes a bracelet that averages $0.60 per bead, we need to write an equation that models this average bead cost. This can be found by taking the total cost of the beads and dividing it by the number of beads used.
1. The total cost of the beads may be found by multiplying the price of each type of bead by the number used, and then adding these values together. Thus:
Total Cost = 0.75x + 3*0.3
= 0.75x + 0.9
2. Total number of beads = x + 3
3. Thus, the average cost is:
(0.75x + 0.9)/(x + 3)
4. Using the value of the average cost per bead given to us ($0.60), we can now write up the full equation:
0.6 = (0.75x + 0.9)/(x + 3)
Answer:
1a)
5 green circles
1 green square
2 red circles
4 red circles
1b) probability is 5/12
Step-by-step explanation:
count for each (1a)
count every shape=12
since there is 5 green circles
the probability is 5/12
You would know 4×5=20 so just add 2 more zeroes cause there is a zero in 40 and in 50
hope this is what you're looking for and made sense
