Answer:
expression for total cost is given by
Step-by-step explanation:
Here we need to find the expression for the total cost
Let us find the cost for x pounds of peanut , y pounds of cashews and z pounds of almonds
cost of 1 pound of peanut = $3.95
cost of x pounds of peanut = $3.95x
cost of 1 pound of cashews = $4.25
cost of y pounds of cashews = $4.25y
cost of 1 pounds of almonds = $5.99
cost of z pounds of almonds = $5.99z
total cost = 
cost after 20% off = total cost - 20% of total cost
= 80% of total cost
cost after 20% off =80%
cost after 20% off =
now we can plug x= 2 , y= 3 and z=1
so we have
cost after 20% off =
=$ 21.31
Answer:
=√41
Steps:
D=√(5-0)²+(4-0)² = √25+16 = √41
The answer for this question is =√41
1: D=√(5-0)²
2: +(4-0)²
3: = √25+16
4: = √41

Answer: tan(70)=x/800
Step-by-step explanation:
Since we are looking at the altitude and x and 800 are given, we will need tangent. Tangent is opposite/adjacent. We can eliminate sin(70). BEtween our 2 tangent choices, the answer is tan(70)=x/800. Tan(70)=800/x is very close but incorrect. 800/x is adjacent/opposite. That is not a trigonometric function.
The answer would be 2/5
4. divided by 2 = 2
—-
10. divided by 2 = 5
2x+y=6
y=3x+4
The resulting equation is
5x=2
where
x=2/5
