Answer:
Given
Step-by-step explanation:
Consider triangle ABD and triangle DCA,
AC=BD ( given that they are diameters)
Diameters of the same circle are equal
AD=AD (common side for both triangles)
<BAD= <CDA (angles in semicircles are 90°)
So since the right angle, hypotenuse and side are equal..
ABD is congruent to CDA
(Rhs congruence rule)
Hence proved..
im assuming the 4 is an exponent, so (2 * 3 * 7)^4 = 2^4 + 3^4 + 7^4 because of the distributive property. the ^4 gets distributed to everything inside of the parentheses.
Answer:
B, E
Step-by-step explanation:
Needs a 3:4:5 ratio, or, if it is an isosceles triangle, then n:n:nsqrt(3)

Answer:
4.732 grams
Step-by-step explanation:
2 US fluid ounces is exactly 59.147059125 mL of volume. 8% of that volume is 4.73176473 mL.
For a solution of this type, where 1 g/100 mL is considered a 1% solution this is the number of grams of solute needed.
About 4.732 grams of solute are needed to prepare 2 fl oz of 8% solution.
_____
We have assumed that 1 gram of solute gives you 1 gram of iodine. Depending on the exact solute used, that may or may not be the case.
