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
Manual is correct due to 5^2 and 7^2 being 74 in total while 5+7 is 12 being squared gives you 144 which is the correct answer.
Answer:
D. M and O are similar but not congruent.
Step-by-step explanation:
To begin, let's eliminate some options.It can't be A. M and O are similar and congruent because M and O aren't congruent because they are different sizes. It cannot be B. O and N are similar and congruent because they aren't congruent since they're different sizes. Lastly, it cannot be C. M and N are similar but not congruent, because these two are actually congruent.
Hello from MrBillDoesMath!
Answer:
4 sin(70) which is approximately 3.76
Discussion:
sin(70) =
side opposite angle/ hypotenuse =
?/4.
As sin(70) = ?/4, multiplying both sides by 4 gives
? =4 sin(70) which is approximately 3.76
Thank you,

2 and 3 because 2 is in 6 timestable and 3 is in 9 as the lowest number
