At the beginning of March, a store bought a rake at a cost of 9$ and marked it up 130%. At the end of the month, the rake had not sold, so the store marked it down 50%. What is the discounted price?
Answer:
the new discounted price is $5.85
Step-by-step explanation:
First convert 130% into a decimal: 130 ÷ 100 = 1.3
Next multiply 1.3 by 9: 9 x 1.3 = 11.7
Then convert 50% into a decimal: 50 ÷ 100 = 0.5
Last multiply 11.7 by 0.5: 11.7 x 0.5 = 5.85

Step-by-step explanation:
In 2005 the U.S. Census Bureau reported that 68.9% of American families owned their homes. Census data reveal that the ownership rate in one small city is much lower. The city council is debating a plan to offer tax breaks to first-time home buyers in order to encourage people to become homeowners. They decide to adopt the plan on a 2-year trial basis and use the data they collect to make a decision about continuing the tax breaks. Since this plan costs the city tax revenues, they will continue to use it only if there is strong evidence that the rate of home ownership is increasing. a) In words, what will their hypotheses be
Answer:
H0 : Number of homeowners stays the same
H1: Number of homeowners increases.
Step-by-step explanation:
The hypothesis is to test if the level of home ownership rises or doesn't.
For this type of experiment,
The null hypothesis is the current level of home ownership.
The alternative hypothesis which is usually the opposite of the null is meant to challenge the claim of the Null. Hence, the null hypothesis will support the claim or hypothesis of the study, which is that the number of homeowners increases, hence, does not remain the same.
Therefore,
H0 : Number of homeowners stays the same
H1: Number of homeowners increases.
William bought some cashews and walnuts. Spending the same amount of money as William, his twin Jillian bought twice as many cashews and 10 less walnuts. If the cost of one walnut is 2 more than the cost of cashew, then what is the minimum possible number of cashews bought by the twins together?
Answer: 33
Step-by-step explanation:
Given
The cost of one walnut is 2 more than the cost of a cashew
Jillian bought twice the amount of cashew as William and 10 fewer walnuts
Suppose the price of cashew and walnuts be x and x+2
Assume William bought a cashew and b walnuts
Money spent by Willian
[tex]\Rightarrow W=a(x)+b(x+2)[/tex]
Money spent by Jillian
[tex]\Rightarrow J=2a(x)+(b-10)(x+2)[/tex]
They spent equal money i.e.
[tex]\Rightarrow ax+bx+2b=2ax+bx+2b-10x-20\\\Rightarrow ax-10x-20=0\\\Rightarrow (a-10)x=20\\\text{Here product of two number is 20 , so both must be greater than 0}\\\therefore a-10>0\\\Rightarrow a>10\\\text{i.e. minimum value of a is 11}[/tex]
The amount of cashew both twins bought is a+2a=3a
[tex]\Rightarrow 3a=3\times 11=33[/tex]

The dependent quantity would be the $12 per hour, while the independent quantities are 30 hrs/ week to 35 hours/ week.
The $12 per hour would become $360/week to $420/week.
The domain of the problem, with the unit of hrs/week, would be :30,31,32,33,34,35.
The Range of the problem, with the unit of $/week, would be : 360, 372, 384, 396, 408, 420.

A bullet fired from a gun has a muzzle velocity of 3510 km per hour how long dies it take to travel 100m
Answer:
A bullet fired from a gun has a muzzle velocity of 3510 km per hour how long dies it take to travel 100m
Step-by-step explanation:
Given :
Velocity of bullet = 3510 km/hr
Distance traveled = 100m
Converting distance in meter to kilometer :
(100 / 1000) km = 0.1 km
Recall :
Speed = Distance /time
Time taken = Distance / speed
Therefore,
Time taken = Distance / speed
Time taken = 0.1 km / 3510 km/hr
Time = 2.849 * 10^-5 hour

A person invests 3500 dollars in a bank. The bank pays 6.25% interest compounded annually. To the nearest tenth of a year, how long must the person leave the money in the bank until it reaches 11100 dollars?
The duration of time period required is 2.4 years.
What is a compound interest?Compound interest simply means that the interest associated with a bank account, loan, or investment increases exponentially over time.
Given that, A person invests 3500 dollars in a bank. The bank pays 6.25% interest compounded annually.
A = P(1+r/100)ⁿ
n = time
A = amount
P = principal
11100 = 3500(1+0.0625)ⁿ
3.171 = (1.0625)ⁿ
Taking log to both sides,
log(3.171) = nlog(1.0625)
n = 2.40
Hence, the required time is 2.4 years.

Answer Choices:
a. (5,5)
b. (2,6)
c. (-4,1)
d. (6,5)
e. (-5,0)
f. none of the above
Answer: C,E
Step-by-step explanation: This is because when we plug in 5 for x and for y in the first inequality we get.
-3(5)-5>-4
Which equals -20>-4 and thats false so thats not it.
Then we got to (2,6) and we plug 2 for x and 6 for y and get:
-3(2)-6>-4
Which is -12>-4 which is false so thats also not it.
Then we got to C and we plug in -4 for x and 1 for y and we get:
-3(-4)-1>-4 and we get 12-1>-4
This is correct so we plug it in to the next inequality and get:
2(-4)-1<-2 and we get -9<-2 which is true
So C is an answer and we go on to d and e
For d we plug in 6 for x and 5 for y and we get:
-3(6)-5>-4 which is -23>-4 which is false so its not d
And then we go to e which is -5 for x and 0 for y and we plug in and we get:
-3(-5)-0>-4 This is 15>-4 which is true so we go to the next inequality and we plug in -5 for x and 0 for y and we get:
2(-5)-5(0)<-2 This is -10<-2 which is true so e is the other answer so the answers are

Find the length of side x in the simplest radical form with a rational denominator.
Answer:
[tex]\sqrt{2}[/tex]
Step-by-step explanation:
We can use either angle, but I'm going to use the one on the bottom. So, in order to find x, we need to use tangent. One side we know is the adjacent, and the side we don't know is the opposite, therefore we need tangent. Here's the equation:
[tex]tan(45)=\frac{x}{\sqrt{2}}[/tex]
Obviously, we can't have a root in our denominator, so we need to get rid of it somehow. Here's how:
We multiply the denominator of the fraction by [tex]\sqrt{2}[/tex]. [tex]\sqrt{2}[/tex] multiplied by itself is simply 2. Try it! We also want to multiply the numerator by [tex]\sqrt{2}[/tex], but there isn't really a number we can use with that, so we'll just add it to the side. The equation you have now is:
[tex]tan(45)=\frac{x\sqrt{2} }{2}[/tex]
Let's try to work this out now. Since the denominator is 2, we have to multiply both sides by it to find x.
[tex]\frac{x\sqrt{2} }{2*2} =x\sqrt{2}[/tex]
[tex]tan(45)*2=2[/tex]
We can plug 2 in for the x in the numerator now:
[tex]\frac{2\sqrt{2} }{2}[/tex]
2 and 2 cancel out, so you get 1 in both the numerator and denominator. That's how we get our answer of [tex]x=\sqrt{2}[/tex]
Also, because this is a 45-45-90 triangle, you don't really have to do all that work. If it's a 45-45-90 triangle, both legs should be the same length. :)
