Identify the trinomial that is a perfect square. 81x^2 − 70x 16 64x^2 − 90x 25 81x^2 − 72x 16 64x^2 − 70x 25

Answers

Hmm
(a+b)^2=(a+b)(a+b)=a^2+2ab+b^2

basically
for
ax^2+bx+c
it is a perfect trinomial when
b=2(√a)(√c)
remember to take both positive and negative roots into consideration
because
(a+b)^2=a^2+2ab+b^2 and
(a-b)^2=a^2-2ab+b^2

see each

first one
-70=2(9)(4)
-70=72
false

second
-90=2(8)(5)
-90=80
false

third
-72=(9)(4)
-72=72
false
but, the last one could be negative
(9x-4)^2 is factor
that is the answer


the answer is 81x^2-72x+16

A drinking glass is shaped like a cylinder with a height of 5 in. and a diameter of 3 in. Maeva adds 25 spherical pieces of ice to the glass. The pieces of ice each have a diameter of 1.1 in. How many cubic inches of water can Maeva add to fill the glass to the rim? Use 3.14 to approximate pi and round your answer to one decimal place.

Answers

First find volume of glass
find volume of ice
subtract


cylinder area=height times are of base

height=5
area of base=circle=pi times radius^2
diameter=2radius
diameter/2=radius
3/2=radius=1.5


pi=aprox 3.14
3.14 times 1.5^2=7.065
7.065 times 5=35.325=volume of glass

25 spereical ice
volume of shqere=4/3 times pi timers r^3
diameter/2=r
1.1/2=0.55
4/3 times 3.14 times 0.55^3=0.696557=1 ice
multiply by 25
17.4139
subtract
35.325-17.4139=17.9111
round to one decimal place
17.9

the answer is 17.9 cubic inches or
17.9 in^3

You are paid $78 for 61/2 hours of work. What is your rate of pay?

Answers

You are paid $78 for 61/2 hours of work.
Question: What is your rate of pay?
=> 78 dollars = is the money paid to you
=> 6 and ½ is the time you rendered for work
=> 6 and half hours = 6.50 hours or 6 hours and 30 minutes
Solution:
=> 78 dollars / 6.5 hours = 12 dollars.
Thus, your rate is 12 dollars per hour (12 dollars/h)

Each player rolls two six sided die once each and the sum of the highest roll wins. The first player rolls a 3 and 4 so that his sum is 7, what is the probability that the secon player will win

Answers

Answer:

5/12 or 41.66%

Step-by-step explanation:

When throwing two six-sided dice, you have 36 possible outcomes:

{1,1} {1,2} {1,3} {1,4} {1,5} {1,6} {2,1} {2,2} {2,3} {2,4} {2,5} {2,6} {3,1} {3,2} {3,3} {3,4} {3,5} {3,6} {4,1} {4,2} {4,3} {4,4} {4,5} {4,6} {5,1} {5,2} {5,3} {5,4} {5,5} {5,6} {6,1} {6,2} {6,3} {6,4} {6,5} {6,6}

To find what is the probability the second player will win, we need to see how many of those 36 possibilities have a combined total of 8 or more (to beat the 7 of the first player):

These 15 combinations have a total of 8 or more:

{2,6} {3,5} {3,6} {4,4} {4,5} {4,6} {5,3} {5,4} {5,5} {5,6} {6,2} {6,3} {6,4} {6,5} {6,6}

So, the probability the second player gets 8 or more and wins is:

15/36 or 5/12 or 41.66%
