I think that the answer is A because you are being asked for the tens place. Since you are looking to identify the place value, choice B and C are automatically eliminated because each place value increases by multiplying by ten. 20 and 60 are not multiples of 10. To identify the tens place, you would have to multiply by ten. I thought of this question in the sense of scientific notations.
Answer:
Slope = - 8
y-intercept = - 4
Step-by-step explanation:
Answer: x= 7/10
Y= 21/5
Step-by-step explanation:
Since the slope is -4 and it is passing through (7,6) so the point slope form of equation can be applied. y-6= -4(x-7)
The formula for the circumference of a circle is C = 2pi*r, where r is the radius. Here, 7850 units = C = 2pi*r.
Dividing 7850 units by 2pi, we get
7850 units
r = ----------------- = 1249 units (to the nearest unit)
2pi
