Answer:
Silver
Step-by-step explanation:
Find the volume of the coin
<u>Volume of a cylinder</u>

Given:
Substituting given values into the formula to find the volume:


Find the density of the coin given it has a measured mass of 18.54 g
<u>Density formula</u>

where:
= density- m = mass
- V = volume
Given:
- m = 18.54 g

Substituting given values into the density formula:


Given:
Therefore, as
the coin is made from silver.
Answer:
15/4, or 3 3/4 is your answer.
Step-by-step explanation:
Isolate the variable, t. Note the equal sign, what you do to one side, you do to the other. Multiply 3/2 to both sides.
(3/2)(2/3)t = (5/2)(3/2)
t = (5/2)(3/2)
t = 15/4
15/4, or 3 3/4 is your answer.

I don’t know how to do these
Answer:
Area = 702.9 or 703
Step-by-step explanation:
By Pythagoras the. first, we need to find the base!
(H)2 = (P)2 + (B)2
(82)2 = (18)2 + b2
6724 = 324 + b2
b2 = 6724-324
b2 = 6100
b = √6100
b = 78.1
note - they all are in square
Now, area of the triangle:-
1/2 * b * h
1/2 * 78.1 * 18
= 702.9
Hope it helps!
This is the isosceles right triangle, the diagonal of a square, the thing that so upset the Pythagoreans. The two sides and diagonal of a square are in ratio
so we get

We could have also gotten this using Trig:


Or by recognizing u=v because remaining angle is 45 so this must be isosceles so
