The price of stock market in at 9 AM was 13.17 then the price has been increasing at a rate of 0.11 each hour at noon the price of stuff he was 13.67 it begins to decrease at the rate of 0.12 each hour if the two rates continue and how many hours were the prices of the two stocks with the same
Answer:
2.26 hours
Step-by-step explanation:
Given that:
Stock 1:
Initial price = 13.17
Rate of increase = $0.11 per hour
13.17 + 0.11h - - - (1)
Stock 2 :
Initial price = 13.69
Rate of decrease = 0.12 per hour
13.69 - 0.12h - - (2)
13.17 + 0.11h = 13.69 - 0.12h
0.11h + 0.12h = 13.69 - 13.17
0.23h = 0.52
h = 0.52 / 0.13
h = 2.26 hours

D. 50 = n(125); 0.4%
Answer:
B 50=n(125) 40%
Step-by-step explanation:
The percent equation, 125 = n(50); 250%
What is percent?A number or ratio which can be expressed as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The percentage therefore refers to a part per hundred. Per 100 is what the word percent means. The letter "%" stands for it. There is no dimension to percentages. As a result, it is known as a dimensionless number. When we say a number is 50% of something, we mean that it is 50% of everything.
As in 0.6%, 0.25%, etc., percentages can also be expressed as decimals or fractions. The grades earned in any subject have been calculated in terms of percentages in academics.
Let the required percentage be x%.
A/c to question,
[tex]\frac{x}{100} * 50= 125\\\\ x=250[/tex]
That is, required percentage is 250%.
Hence, option C is correct.

We went to the market to buy some fruit. We decided to buy some apples, strawberries, and oranges. If we buy 2 apples, 3 boxes of strawberry, and 4 oranges, the fruit would cost $15.30. If we buy 1 box of strawberry, 4 apples, and 2 oranges, the fruit would cost $10.90. If we buy 1 orange, 5 apples and 2 boxes of strawberry, the fruit would cost $13.70.
Answer:
The answer is below
Step-by-step explanation:
Let x represent the cost of apples, y represent the cost of strawberries and z represent the cost of oranges.
The money used to buy 2 apples, 3 boxes of strawberry, and 4 oranges is represented as:
2x + 3y + 4z = 15.3 (1)
The money used to buy 4 apples, 1 boxes of strawberry, and 2 oranges is represented as:
4x + y + 2z = 10.9 (2)
The money used to buy 5 apples, 2 boxes of strawberry, and 1 oranges is represented as:
5x + 2y + z = 13.7 (3)
Solving equation 1, 2 and 3 simultaneously gives:
x = $1.5, y = $2.5 and y = $1.2
The cost of orange is $1.5, cost of strawberry = $2.5 and cost of orange = $1.2

Can someone help me know how to do this problem In finding what I can put in for (c) in order to get 2 imaginary solutions
Answer:
To get 2 imaginary solutions, c must be less than -2
Step-by-step explanation:
The general form of the quadratic equation is:
[tex]ax^2+bx+c=0[/tex]
Solve the quadratic equation by using the formula:
[tex]\displaystyle x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]
The equation to solve is:
[tex]-2x^2+4x+c=0[/tex]
In our equation: a=-2, b=4, c=unknown
For the roots to be imaginary, the argument of the square root must be negative, that is:
[tex]b^2-4ac<0[/tex]
Substituting the known values:
[tex]4^2-4(-2)c<0[/tex]
[tex]16+8c<0[/tex]
Subtracting 16:
[tex]8c<-16[/tex]
Solving:
[tex]c<-2[/tex]
Thus, to get 2 imaginary solutions, c must be less than -2

Which single conversion factor would you use to find out how many miles are in 8,462 yards?
Answer:
A. 1 mile / 1,760 yards
Step-by-step explanation:
A single conversion factor is a number that we can multiply directly with 8,462 yards to determine how many yards are there in 8,462 yards.
Since 1 mile is to 1,760 yards, the single conversion factor to use in determining how many miles a number of yards would be = 1 mile/1,760 yards = [tex] \frac{1}{1,760} [/tex]
Thus, to find out many miles are in 8,462 yards, multiply by [tex] \frac{1}{1,760} [/tex].
[tex] 8,462*\frac{1}{1,760} = \frac{8,462}{1,760} = 4.8 [/tex] miles

What is the sales tax on a $14,500 truck if the tax rate is 9%. What is the total price of the truck
after the sale tax?
Answer:
in order to find percentages you have to multiply the base cost by the tax and then divide it by 100
Step-by-step explanation:
base price is 14500
tax rate is 9 percent
(14500 × 9 ) ÷ 100
or you can just do this
14500 × 0.09 = 1305
since multiplying by 9 then dividing by 100 is equal to multiplying by 0.09 (9/100)
14500+1305= 15805

underestimate of the circle
overestimate of the circle
same as the circle
does not compare
Answer:
I think the answer is underestimate of the circle
Step-by-step explanation:
I believe it is underestimate because the dodecagon is inside the circle, therefore smaller than the circle. It wont fill the circle completely so that is why i think it is underestimate. I hope this helps, if not I am really deeply sorry!!!!!
