Answer:
120 mph
Step-by-step explanation:
Distance = rate * time
D = 70 miles
t = 35 minutes
So that gives us:
70 mi = r(35 min)
Divide both sides by 35 min:
70/35 mi/min = r
simplify:
2 mi/min = r
If you wish to convert to miles per hour, remember that there are 60 minutes in an hour:
2 * 60 = 120
120 mph = r
Answer: 10 cm
Step-by-step explanation:
The circumference of the CD = 22\pi
We know that the formula of the circumference is:
Circumference = 2\pi r
We will substitute the value of circumference to find the radius:
22 pi = 2 x pi x r
r = 11
Therefore its radius will be 22 / 2 = 11 cm
Jamie wants to cut the CD from the middle of the CD to one side but leaving one cm. To find the measurement of the cut portion, we will subtract 1 from 11 to get:
11 - 1 = 10 cm
Answer:
x^2 - 6x + 147 so the coefficient is 1
Step-by-step explanation:
First, simplify the equation.
1. 2/3x(2x-3) = (2x/3)(2x-3)-(x-7)(x+7)
2. 2x-3(2x/3) = (2x(2x-3)) - (x-7)(x+7)
3. Expand -(x-7)(x+7) = -x^2+49
Combine to get (x^2 - 6x)/3 +49
Simplify to get x^2 - 6x + 147. The coefficient of the quadratic term is one.
Answer:
1.) -5.1
2.) personally I would not convert the way the would. There is a quicker way of converting that to decimal so idk exactly what they are doing unfortunately I can't help with you at the moment. I would need more time.
3.) Point C is the the opposite of -3.3
4.) D. 5.3333333 is a rational number
5.) All the points on the graph could represent rational numbers
6.) Simply Divide 2 by 6 to get repeating decimal
7.) -20.75 should be correct
