X = 30
You have to do 36 squared take away 16 squared and then square root it. You take away because you aren’t finding the hypotenuse ( the line opposite the right angle) but if you where finding hypotenuse you would add instead.
Answer:
Total amount that Matthew's bank will receive is $10099.81.
Step-by-step explanation:
We need to find the amount Matthew's bank will receive after lending him $8,000 for four years at an interest rate of 6 percent, compounded annually.
The formula for compound interest is:
![A=P(1+r)^n](https://tex.z-dn.net/?f=A%3DP%281%2Br%29%5En)
Where A = future value
P= Principal Amount
r = interest rate
and n= time
So in the question we are given:
P= $8000
r = 6% or 0.06
t = 4 (since 4 yeras compounded annually)
A= 8000*(1+0.06)^4
A= 8000*(1.06)^4
A= 10099.81
So, total amount that Matthew's bank will receive is $10099.81.
Answer:
2(x-9) = 2
Step-by-step explanation:
Difference indicates subtraction:
The difference of a number and
9
is
(
x
−
9
)
Twice the difference means
2
(
x
−
9
)
We know that the answer to this is
2
, so as an equation:
2
(
x
−
9
)
=
2
If you solve it we would have:
x
−
9
=
1
←
÷
2
x
=
1
+
9
x
=
10
The difference between
10
and
9
is
1
and twice
1
is
2
.
The number is correct.
Note that written as:
The difference of twice a number and
9
would have a different expression. This would be
2
x
−
9
I think that it is D as if X = Us $ and the function h(x) is the euros whatever number you put in as x whatever it equals is euros
Hope this makes sense
We can bring the ratios to a similar form, because 2:5 is the same as 4:10 (we can mupltiply rations by the same number)
so one ratio is 4:10 and the other is 4:15 and the difference is is 75 beads
in this ratio, we can see each number corresponding to a "unit" of beads: that means that what changed is that Patricia now has 5 more such groups (15-10=5), and since she has 75 beads more each unit must be 75/5=15.
so afterwards (and before) Karen had 4 such units, that is 60, and Patricia before had 10 such units, that is 150.
