Answer:
tax = $6.63
Step-by-step explanation:
We can find the tax by multiplying the original amount by the tax rate.
tax rate = 10 % = .1
tax = 66.30 * .10
= 6.63
Answer:
Part A
x + y ≤ 460
2.5·x + 1.25·y ≥ 600
Part B
192 bottles
Step-by-step explanation:
The given parameters are;
The selling price of a can of lemonade = $2.50
The selling price for each bottle of water = $1.25
The amount the club needs to raise to cover the cost of renting costumes, A = $600
The maximum acceptable cans and bottles = 460
Part A
Let 'x', represent the number of cans of lemonade accepted by the students, and let 'y' represent the number of bottles of water accepted, we have;
The situation can be represented by the following system of inequalities
x + y ≤ 460
2.5·x + 1.25·y ≥ 600
Part B
The number of cans of lemonade sold, x = 144
Therefore, we have;
2.5 × 144 + 1.25·y ≥ 600
1.25·y ≥ 600 - 2.5 × 144 = 240
1.25·y ≥ 240
y ≥ 240/1.25 = 192
y ≥ 192
The least number of bottles of water that must be sold to cover the cost of renting costumes, y = 192 bottles
Answer:
<u>The standard deviation of the uniform distribution is:</u>
<u>U(3, 12)</u>
- σ = (12−3)/√12 = 9/√12 = 2.5981
<u>U(80, 250)</u>
- σ = (250−80)/√12 = 170/√12 = 49.0748
<u>U(4, 93)</u>
- σ = (93−4)/√12 = 89/√12 = 25.6921
Answer:
234.784 ~ 235
Step-by-step explanation:
One side = 210
other side = 105
a2+b2 = c2
210 ^2 + 105 ^2 = c2
55125 = c ^2
c = 
= 234.784 ~ 235
hope its right!!!
