Answer:
5 -2√10 = C
Step-by-step explanation:
√25 -√40
√25 = √5 x5 = √5² = 5
√40 = √5 x 8 = √5x 2x4 = √10x4 = √10x 2² = 2√10 (when the 2 comes back into the square root it become 2²)
√25 -√40 = 5 -2√10
Treat as fraction
28/4
common factor is 4
divide by 4 or undistribute the 4
7/1
7:1 is simplifed ratio
The rate is 255 MPH.
The jet can fly 3,825 miles in 15 hours.
Answer:
y= 407.54654 ft
Step-by-step explanation:
This is an exponential decay functions
y = ab^x where a is the initial value and b is ( 1 - rate of decay)
a = 520
b = 1- 3%
y = 520 ( 1- .3) ^x
y = 520 ( .97) ^x
We want x to be 8 weeks
y = 520 ( .97) ^8
y= 407.54654 ft
The answer is he will make $300 commission for 25 TV sets sold. The first thing you need to do is find out how much commission he makes on each TV. So we take $120 and divide by 10% and that gives us $12. So $12 is the amount of commission per TV. Then we just need to multiply the $12 by 25 TV sets. That gives us the answer of $300 commission total.
A second way to solve this problem is by taking the $120 and multiplying that by the 25 TV sets. That gives you $3,000 total for the 25 TV sets. Then you just divide the 10% commission Mike will make. That also gives you the answer of $300 commission.
