Answer:
C) $877.50
Step-by-step explanation:
Time t = 4 years
Principal, p = $750
rate, r = 4.25% = 0.0425
Amount that will be in her account in four years =
Simple interest (prt/100) + principal
750 * 4.25* 4 / 100 + 750
127.5 + 750
= $877.50
4.2³ = 74.088. If the 4.2 is accurate, this is actually not an estimate but an exact answer. You can of course round it to 74, then it becomes an estimate.
Your answer is D){28, 42, 56, 70, 84}
To answer this question you just have to make sure the amount he pays is a multiple of 7.If you know you times table then this should be easy
Times table of 7:
7,14,21,28,35,42,49,55,63,70,77,84.
Now you just need to find an answer choice who has these numbers.Lets check it out!
A) 11 isn't a multiple of 7
B) 56 isn't a multiple of 7
C) None of these are multiples of 7 except 7 so this is also incorrect
D) This is correct because they are all multiples of 7
Hope this makes sense.
the equation framed in the form of y=kx is and , x as a function of y .
<u>Step-by-step explanation:</u>
Here we have , The amount Lin's sister earns at her part-time job is proportional to the number of hours she works. She earns $9.60 per hour. We need to find an equation in the form y=kx to describe this situation, where x represents the hours she works and y represents the dollars she earns.Is y a function of x . Also , Write an equation describing x as a function of y . Let's find out:
Here , Lin's sister earns $9.60 per hour . Let x represents the hours she works and y represents the dollars she earns . So , According to question following is the equation framed in the form of y=kx :
⇒
Yes, y is a function of x , as a straight line with a slope of 9.6
Now , x as a function of y :
⇒
⇒
Therefore , the equation framed in the form of y=kx is and , x as a function of y .
Answer:3.14r^2
Step-by-step explanation:
if you are asking circumference then using circumference formula
circumference(c)=pi*r^2
=3.14r^2
