Answer:
Ty covered the least distance per min.
Step-by-step explanation:
Who covered the shortest distance per minute, or who rode his bike most slowly?
Andre's rate: (750 m) / (3 min) = 250/3 m/min
Rick's rate: (800 m) / (4 min) = 200 m/min
Ty's rate: (950 m) / (5 min) = 190 m/min
Ty was the rider who covered the least distance per minute; his rate was the slowest.
Answer:
15.4 gallons .
Step-by-step explanation:
The rate of gas used = 380/14 = 27.14 gallons per gallon.
So for each gallon used you drive 27.14 miles.
So number of gallons used when travelling 418 miles = 418/27.14
= 15.4 gallons .
Answer:
b.the system of the equations has exactly one solution at(-4.3).
Step-by-step explanation:
![\sqrt{p} = \sqrt[r]{w - {as}^{2} }](https://tex.z-dn.net/?f=%20%5Csqrt%7Bp%7D%20%20%3D%20%20%5Csqrt%5Br%5D%7Bw%20-%20%20%7Bas%7D%5E%7B2%7D%20%7D%20)
Find raise each side of the expression to the power of r
That's
<h2>
![( \sqrt{p} )^{r} = (\sqrt[r]{w - {as}^{2} } ) ^{r}](https://tex.z-dn.net/?f=%28%20%5Csqrt%7Bp%7D%20%29%5E%7Br%7D%20%20%3D%20%20%28%5Csqrt%5Br%5D%7Bw%20-%20%20%7Bas%7D%5E%7B2%7D%20%7D%20%29%20%5E%7Br%7D%20)
</h2>
we have
<h2>
</h2>
Send w to the left of the equation
<h2>
</h2>
Divide both sides by - a
We have
<h2>
</h2>
Find the square root of both sides
We have the final answer as
<h2>
</h2>
Hope this helps you
Law of sines in a triangle with angles A, B, C and sides a,b,c states that
(sin A)/a =(sinB)/b = (sinC)/c
To use the above ratios, you need at least one angle and one side and one of either an angle or a side. So SSS and AAA don't work
