was also able to determine that the bar had 30 ounces of silver. What
percent of the weight of the bar was silver?

Answers

Answer 1
60%
If you take the 30% and divide from the 50% you get .6 multiply that by a 100 you get 60.

30/50=.60
.60x100=60
60%

Question 1: square root of 109

Question 2: 2, 1, 1

Question 3: True

Step-by-step explanation:

The square root of 109 is about 10.4 which is greater than 5 and 9.

In the equation a^2 + b^2 = c^2, a and b represent the legs of a triangle and c represents the hypotenuse.

The Pythagorean Theorem states that For all right triangles the square of the hypotenuse is equal to the square of both sides. (a^2 + b^2 = c^2)

Please help I’m confused math is hard!

Answers

Answer:

Step-by-step explanation:

basically, what they are asking you is to factor and then plug in the values (x=3; x=4) that they gave you.

first, you need to factor out the equation.

start with the original equation.

V=4x^3+10x^2+4x

factored form:

V= 2x(2x^2+5x+2)

next, you're going to want to plug in the values.

the answer asks for x=4, but you should do both.

v=2(3)(2(3)^2+5(3)+2)

do not forget to do the exponents before!

v=6(18+15+2)

v=6(35)

v=210 ft^2

that's the answer for if x was equal to 3.

V= 2x(2x^2+5x+2)

don't forget to write the original equation first.

V=2(4)(2(4)^2+5(4)+2)

V=8(36+20+2)

V=464 ft^2

How much will Jason earn, if he invests $8,000 at 7.5% interest rate for 18 months? How much will be in the account at the end of the 18 months?

Answers

Answer:

$8,900

Step-by-step explanation:

You don't say anything about compounding. If this problem involves only simple interest, then the interest will be i = p*r*t and the account balance will be i + p.

Here i = $8,000*0.075*1.5 (representing 18 months)

         i + $900

At the end of 18 months there will be $8,000 + $900, or $8,900, in the account.

Whoever helps me out with this problem, thanks a lot!

Answers

Answer:I would presume 15

Step-by-step explanation:

I haven’t done any math yet but they should each have 1 head

5 parrots and 10 puppies

Each parrot has 2 feet so 5*2 = 10. Each puppy has 4 feet so 4*10= 40. So 40+10= 50 feet and 10+5= 15 heads

Answers

Answer:

B.

Step-by-step explanation:

First, (3/2) is greater than 1, which therefore eliminates A and D.

Second, you must determine if the triangle gets larger or smaller. Lets suppose that X = 2 and Y = 3. If we were to multiply both of these values by (3/2), our points would change to X = 3 and Y = 4.5

Since there was an increase, this means that the triangle was larger.

This leaves B as the answer.

Remember: Any scale value greater than 1 is an enlargement, as proven by the hypothetical.

They use birth records, marriage licenses, real estate purchases, death certificates, and military enlistments to trace ancestors and family trees. Most genealogists are hobbyists who only follow their own family names as far back into history as possible. However, there are professional genealogists who can trace the lives of well-known people or royalty back for generations.Originally, the government of ancient Rome kept censuses and tax records, but most of that information is lost. After the establishment of the Catholic Church, most people in Europe kept track of their ancestors through church and parish congregation rolls. In other civilized parts of the world, the procedure was similar. However, in less civilized cultures, it was difficult to keep track of family lines, and most of the family trees were kept orally, with names passed down from parent to child. Occasionally, cultures composed songs and poems to remember ancestors.After the invention of the printing press, things became much simpler to keep track of family lines. When the Bible was mass produced, most families kept a copy and handed it down through generations. Births, marriages, and deaths were recorded in the family Bible, so families began to trace their kinship through writing. The printing press also allowed government agencies to keep better record of municipal and state censuses. Human beings began to leave more of a paper trail through the centuries.With the creation and use of the World Wide Web, genealogy has exploded. Everyone with an internet connection has easy access to government databases and library records dating back hundreds of years. Social networking websites cater to amateur genealogists and make it simple to assemble a family tree with a little help. Now it is entirely possible to access records across oceans and continents without having to travel to a foreign place to research in a library or office. As peoples lives become more recorded, tracing genealogies will be as simple as pushing a button or flipping a switch.Which question is most likely raised by this article?A.Who is the leading genealogist in the world today?B.Where can a person find an antique printing press?C.What do genealogists have to look forward to in the future?D.Why is it important to research your family tree?
