We need to know some log properties
1. when the base is not stated, assume that it is base 10 or log₁₀
2.
-log(10^-1)=
answer is D. -1
Answer:
A
Step-by-step explanation:
the last number is the y intercept so the intercept in the line is -3.5 so I just matched them up.
Answer:
8 + 1.50x + 0.75y = 19.25
Step-by-step explanation:
Let the number of additional inch = x
Let the number of toppings = y
From the question,
A 10-inch cheese pizza costs $8.
Each additional inch costs $1.50
Each additional topping costs $0.75.
The equation that represents Josh's pizza is when his total cost amounts to $19.25 is:
$8 + $1.50 × x + $0.75y = $19.25
8 + 1.50x + 0.75y = 19.25
Step-by-step answer:
The steps are much easier to follow when we know how many product it sells. The number does not really matter, because we need the profit per item.
Say, the company made and sold 100 items of the product.
The revenue = 100*5 = $500.
On the average, 2 out of 100 are defective and need to be replaced at a cost of $100 each, so
replacement cost = 2* 100 = 200
So net profit for 100 items = $500 -$200 = $300
Net profit for each item = $300/100 = $3.00
Remark: since the product is replaced, no refund is necessary, so revenue stays at $300.
The answer is 88 because if you add 5+3 and then multiply by 11, you would equal out to 88 dogs and cats
