Answer:
B
Step-by-step explanation:
r^2 is 0.9997, and after 10 years it'll be 95660
To work out how much Luz earns, you simply have to follow 400/40=10, so
she earns $10/hour. We can therefore establish that if she works for 6
hours, she'll earn $60.
Answer:
9%
Step-by-step explanation:
Cost of 1/5 good = 1500*1/5= 300
Profit= 5%
SP = (profit+100)/100*CP
SP= (5+100)/100*300
SP = 105/100*300
SP= 1.05*300= 315
Cost of 4/5 good = 1500*4/5= 1200
Profit= 10%
SP= (profit+100)/100*CP
SP= (10+100)/100*1200
SP = 110/100*1200
SP= 1.10*1200= 1320
Total SP = 315+1320= 1635
Net profit= 1635-1500= 135
Profit% = 135/1500*100%
Profit% = 0.09*100%
Profit% = 9%
Answer:
-20
Step-by-step explanation:

According to PEMDAS, we need to do the math in the parentheses first.

Applying PEMDAS to the inside of the parentheses, then we have to divide -6 by -1, where we would get 6.

Adding a negative is the same as subtracting, so adding negative 10 is the same as subtracting 10.

Subtracting, we get 6 - 10 = -4 and we're left with:

Multiplying, <u>our final answer is -20.</u>
Hope this helps!
Answer:
y=7x-188
Step-by-step explanation:
We know that this line must have a slope of 7, because this line is parallel to y=7x+13
We must use the point slope formula: y-
= m(x-
)
Next, we will plug in the point (28,8) for
and
, and 7 in for m
y-8=7(x-28)
Solve the equation, first by distributing the 7
y-8=7x-196
Add the 8 over
y=7x-188
