Answer:
The equation that represents the battery charge in Sanchez's phone as a percentage t hours after he left his house is B(t) = 30 - 3*t.
Step-by-step explanation:
The initial state of the battery on Sanchez's phone is 30% so in time t equals zero the battery should be at that value and as time progresses the battery should lose battery charge at a rate of 3% for each hour. We can write this in an equation form by taking the initial state and subtract it by the rate multiplied by the value of time. We have:
B(t) = 30 - 3*t
The equation that represents the battery charge in Sanchez's phone as a percentage t hours after he left his house is B(t) = 30 - 3*t.
Answer:
C.67
Step-by-step explanation:
Use the Pythagorean Theorem to solve this. First find the missing side. 23 squared plus 16 squared. Which equals 785 then you just find the square of that and it is 67.
Answer:
it is an adjacent/linear pair
Answer:
Step-by-step explanation:
Let the horizontal distance is x
<u>Use tangent to solve this:</u>
- tan 30° = 6/x
- x = 6 / tan 30°
- x = 10.4 mi (rounded)
![2(x+6)+40=4x\\2x+12+40=4x\\2x+12+40-4x=0\\2x-4x+52=0\\-2x+52=0\\-2x=-52\\x=26](https://tex.z-dn.net/?f=2%28x%2B6%29%2B40%3D4x%5C%5C2x%2B12%2B40%3D4x%5C%5C2x%2B12%2B40-4x%3D0%5C%5C2x-4x%2B52%3D0%5C%5C-2x%2B52%3D0%5C%5C-2x%3D-52%5C%5Cx%3D26)
Basically multiply the 2 inside the bracket, then addition and subtraction. For the -2x=-52 part. Move -2 to divide the -52, you'll get x = -52/-2 as you'll get x = 26 because minus * minus or minus divide minus will always be positive.
