Answer:
34.54 in (Answer C)
Step-by-step explanation:
The formula for the circumference of a circle whose radius is known is
C = 2πr.
Here, r = 5.5 and π ≈ 3.14, and so the circumference of the circle is
C = 2(3.14)(5.5 in) = 34.54 in (Answer C)
Answer:
2
Step-by-step explanation:
the y-intercept is where the line meets the y-axis
Answer:
slope = 2
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 2x + 4 ← is in slope- intercept form
with slope m = 2
To get the length of the hypotenuse, we use the equation a² + b² = c².
a and b are the lengths of the legs, and c is the hypotenuse. In this case, the legs are 3 and 4. So, plug them into the equation.
3² + 4² = c²
Now, solve for c
9 + 16 = c²
25 = c²
5 = c
Since c is 5, that means the hypotenuse is 5 cm.
Answer:
2.50+1.95x=27.64, x=12.89
Step-by-step explanation:
2.50+1.95x=27.46 =》 1.95x=27.64-2.50 =》 x=(27.64-2.50)/1.95 =》 x=12.89
