$39.76
Step-by-step explanation:
9.96 + 10.05 + 19.75 = $ 39.76
Answer:
I think its 6 numbers . See below
Step-by-step explanation:
The numbers must end in 0 because they must be divisible by 2 and 5
240 is one number it is the first number between 200 and 500 which is divisible by the 5 numbers.
The LCM of the 5 numbers is 60 so we can add 300, 360, 420 and 480 to the list.
Answer:
The converse of Pythagorean Theorem states:
<em>If the square length of the longes side of a triangle is equal to the sum of the squares of the other two sides, then it's a right triangle.</em>
<em />
We use the converse of Pythagorean Theorem to prove that a triangle is a right triangle. It's like the inverse use of the theorem. Often, this theorem is used to find the length of a side of a triangle when we already know it's a right triangle. However, when we don't know that is a right triangle, we use the converse to prove it.
Answer:
The speed of the truck is 42 mph
Step-by-step explanation:
we know that
The speed is equal to divide the distance by the time
Let
s -----> the speed in miles per hour
d ----> the distance in miles
t ----> the time in hours
![s=\frac{d}{t}](https://tex.z-dn.net/?f=s%3D%5Cfrac%7Bd%7D%7Bt%7D)
![d=s(t)](https://tex.z-dn.net/?f=d%3Ds%28t%29)
step 1
Find out the distance traveled by the car at 7:00 P.M
we have
![s=46\ \frac{mi}{h}](https://tex.z-dn.net/?f=s%3D46%5C%20%5Cfrac%7Bmi%7D%7Bh%7D)
![t=7:00 P.M-4:00 P.M=3\ h](https://tex.z-dn.net/?f=t%3D7%3A00%20P.M-4%3A00%20P.M%3D3%5C%20h)
![d=s(t)](https://tex.z-dn.net/?f=d%3Ds%28t%29)
substitute the values
![d=46(3)=138\ mi](https://tex.z-dn.net/?f=d%3D46%283%29%3D138%5C%20mi)
step 2
Find out the speed of the truck
we know that
At 7:00 P.M the distance is equal to
![d=264-138=126\ mi](https://tex.z-dn.net/?f=d%3D264-138%3D126%5C%20mi)
![t=7:00 P.M-4:00 P.M=3\ h](https://tex.z-dn.net/?f=t%3D7%3A00%20P.M-4%3A00%20P.M%3D3%5C%20h)
substitute
![s=\frac{126}{3}](https://tex.z-dn.net/?f=s%3D%5Cfrac%7B126%7D%7B3%7D)
![s=42\ \frac{mi}{h}](https://tex.z-dn.net/?f=s%3D42%5C%20%5Cfrac%7Bmi%7D%7Bh%7D)
9^c = 243
3^(c)*2 = 243
3^(c)*2 = 3^5
Since the bases are the same the powers can be equated.
2*c =5
c = 5/2
c = 2 1/2
Check
9^2.5 = 243
