Answer:
57/32
Step-by-step explanation:
171/32 divided by 2 2/3
2/5 + 6/7 + 2/3....lowest common denominator is 105
42/105 + 90/105 + 70/105 = 202/105 =1 97/105 or 1.92 miles
The first graph is B. x^2 + 6 < 3
It is a parabola and opens upward when x^2 is positive. 6 raises it upwards by 6 units. the circle at
x = 3 means that the function can approach but not be equal to 3.
So Sahra is 3 times as old as her daugter. That means that the sum of their age is the daughters age times 4.
We can prove that by saying the daughters age is x. Sahra's age must be 3x. Their sum must be x+3x = 4x.
So to get the daughters age we divide the sum by 4, which is 8.
Answer:
A
Step-by-step explanation:
The formula that relates current, power and resistance is
![I=\sqrt{\frac{P}{R}}](https://tex.z-dn.net/?f=I%3D%5Csqrt%7B%5Cfrac%7BP%7D%7BR%7D%7D)
Where
I is the current (in amperes)
P is the power (in watts)
R is the resistance (in ohms)
We know P = 500 and R = 25, we plug them into the formula and solve for I:
![I=\sqrt{\frac{P}{R}}\\I=\sqrt{\frac{500}{25}}\\I=\sqrt{20}\\ I=4.47](https://tex.z-dn.net/?f=I%3D%5Csqrt%7B%5Cfrac%7BP%7D%7BR%7D%7D%5C%5CI%3D%5Csqrt%7B%5Cfrac%7B500%7D%7B25%7D%7D%5C%5CI%3D%5Csqrt%7B20%7D%5C%5C%20I%3D4.47)
Correct answer is 4.47 Amperes, or choice A.
