Answer:
Step-by-step explanation:
The hardware store has 200 paintbrushes. They order 9 boxes with 12 paintbrushes each. This means that the total number of paintbrushes that was ordered is
12 × 9 = 108
Therefore, the total number of paintbrushes that the store has would be
200 + 108 = 308
They sell 11 boxes that have 6 paintbrushes each. This means that the total number of paintbrushes that they sold is
11 × 6 = 66
Therefore, the number of paintbrushes left would be
308 - 66 = 242
The manager's estimate is reasonable. They ordered about 120 paintbrushes and sold about 60 of them so they should have about 60 more paintbrushes than they started with.
Answer:
Slope: 1
Y-Intercept: (0,4)
Equation: y=1x+4
Step-by-step explanation:
To solve for slope you need to pick 2 points on the graph (ex. 2,6 and 4,8 ), then you use the formula to find the slope.
For Y-Intercept you just look for where the line intercepts on the y-axis (ex. 0,4).
If the line doesn't touch the origin (0,0), then it isn't proportional.
For the equation it's y=mx+b or, if its proportional then y=mx. The Y-Intercept will always be <em>b</em>. The slope represents <em>m.</em> The <em>x </em>is the variable.
25% of the 9th grade belongs to more than one club.
9th grade population 180
1 club = 90
2 clubs = 33
3 or more clubs <u>= 12</u>
Students w/ clubs 135
2 clubs + 3 or more clubs = 33 + 12 = 45 ÷ 180 = 0.25 x 100% = 25%
1 club = 90 ÷ 180 = 0.50 x 100% = 50%
no club = 180 - 135 = 45 ÷ 180 = 0.25 x 100% = 25%
Answer:
solution,
hope this helps...
