Answer:
Leah has 15 stickers left.
Step-by-step explanation:
The total number of stickers that Leah had was 50. Leah gave 1/2 of the stickers to her sister. This means that the number of stickers that Leah gave to her sister was: 1/2 × 50 = <u>25 stickers</u>
.
Of the amount left, she gave 2/5 to her brother. This means that the number of stickers that Leah her brother was
: 2/5 × 25 = <u>10 stickers
</u>.
Therefore, the number of stickers that Leah have left for herself is
:
50 - (25 + 15)
= 50 - 35
= <u>15 stickers</u>
I hope this helps you!
Have a great day! :)
Answer:
x≠-1,1
Step-by-step explanation:
f(g(x)) is a composition where g(x) is is substituted for x in f(x).
Recall, f(x) is 2/x. So we write 2/|x|-1. This places x in the denominator and 0 cannot be in the denominator x. Any value of x that makes the denominator 0 will not be in the domain.
|x|-1=0
|x|=1
x=1,-1
Answer:
Quarterly interest rate= 0.8974%
Step-by-step explanation:
Giving the following formula:
Initial investment (PV)= $3,500
Future Value (FV)= $6,200
Number of periods (n)= 16*4= 64 quarters
<u>It is almost impossible to calculate the interest rate using a formula. To determine the interest rate, we need to use a financial calculator:</u>
Function: CMPD
n= 64
I%= SOLVE= 0.8974
PV= 3,500
FV= -6,200
Quarterly interest rate= 0.8974%
