take the number to the right of the underlined digit. if its 4 or less, the digits of the underlined one to the left stay the same, while the digits on the right are turned into 0's.
I'll do a few to help you out:
1. *1*60,656 = 200,000
2. *1*49,590 = 100,000
3. 117,*8*21 = 117,800
Answer:
Mass m = 20.04 grams
Correct question;
Sinker is a weight used by fishermen. A fisherman uses a sinker in the shape of a sphere with radius 0.75 cm. The sinker is made of lead, which has density 11.34g/cm^3. What is the mass of the sinker?
Step-by-step explanation:
Mass of an object can be defined as
Mass m = density p × Volume V
Given;
Density of the sinker = 11.34g/cm^3
Radius of the sinker = 0.75 cm
And we know that the volume of a sphere is given as;
V = 4/3 × πr^3
Substituting r, we have;
V = 4/3 × π × 0.75^3
V = 1.767 cm^3
Then we can calculate mass as;
m = pV
m = 11.34×1.767
m = 20.03778 g
m = 20.04 grams
Answer:
a1
Step-by-step explanation:
Circumference=2piradius
Using that, you need to find the radius (which is one half of the diameter) 72/2=36
That is when you can plug the radius in: Circumference=2pi36
2*36=72. 72*pi is 72pi, or if you want to use 3.14, 72*3.14=226.08
5+(1/7)b=-2
First subtract 5 from both sides. Our goal is to isolate b.
5+(1/7)b-5= -2-5
(1/7)b= -7
Now multiply both sides by 7 because (1/7)*7= 7/7 or 1.
7* (1/7)b= -7*7
1b= -49
Final answer: b= -49
