Answer:
$90
Step-by-step explanation:
We use the simple interest formula,
I = Prt
where
I = interest
P = principal amount = $500
r = interest rate = 6% = 0.06
t = time = 3 years
I = Prt
I = $500 × 0.06 × 3
I = $90

A salt-water tank needs to contain 5 gallons of water for each 1-inch fish. If lan has a 30-gallon tank, predict how many inch-long fish he can have. S
Answer:
6in
Step-by-step explanation:
Let's organize what we know.
- 5gal/1in
- 30gal tank
Since we need to find the inches of the fish he can have, we can set up a proportion like this:
5/1=30/x
We can cross multiply.
5x=1(30)
Simplify: 1*30=30
5x=30
Now we can isolate the variable.

For which values of c does the quadratic equation x^2-2x +c=0 have
One root equal to zero and one negative root
Answer:
There is no values of c that makes it true
Step-by-step explanation:
The roots of the quadratic equation x² – 2x + c = 0 are 0 and –2. Then the value of c is zero.
What is a quadratic equation?It is a polynomial that is equal to zero. Polynomial of variable power 2, 1, and 0 terms are there. Any equation having one term in which the power of the variable is a maximum of 2 then it is called a quadratic equation.
For which values of c does the quadratic equation
x² – 2x + c = 0 ...1
The one root is equal to zero and one negative root.
Let negative a be the one root.
x = 0, –a
Then we have factorized the equation,
(x)(x + a) = 0
On solving, we have
x² + ax = 0 ...2
In comparing equation 2 with equation 1, we have
a = –2 and c = 0

There are two jars once I contains two red gumballs three green gumballs and one yellow gumball. The other jar contains two blue balloons in three purple balloons. Jeff randomly draws one gumball and then one balloon what is the probability will get one red gumball and one blue balloon
Answer:
P(1 red gumball and 1 blue balloon) =[tex]\frac{2}{15}[/tex]
Step-by-step explanation:
There are two jars.
One jar has 2 red, 3 green and 1 yellow gumball.So, there are 2+3+1=6 gumballs.
Another jar has 2 blue and 3 purple balloons. Totally there are 2+3=5 balloons.
So,
Probability of drawing 1 red gumball from jar 1 =[tex]\frac{2}{6}[/tex]
Probability of drawing 1 blue balloon =[tex]\frac{2}{5}[/tex]

The equation of a linear function is y = –2x + 3. Which table contains a set of points that lie in the graph of this function?
Answer:
The answer is A)
Step-by-step explanation:
To find out table contains a set of points that lie in the graph of this function , we have to hit and trial method ,
when we put the value of x in y = –2x + 3 this equation so ,
taking x = 1 , then the value of y is
=> y = -2(1)+3
=> y = -2+3
=> y = 1
taking x = 0 , then the value of y is
=> y = -2(0)+3
=> y = 3
now talking x = -3 , then the value of y is
=> y = -2(-3) +3
=> y = 6+3
=> y = 9
so , the option A is the right answer
Answer:
A)
Step-by-step explanation:
Given linear function: y = -2x + 3
Therefore, the slope is -2 and the y-intercept is (0, 3)
Therefore, we are looking for a set of ordered pairs that has a rate of change of -2
⇒ as the x-value increases by 1 unit, the y-value decreases by 2 units
i.e. as the x-value decreases by 1 unit, the y-value increases by 2 units.
The only set of ordered pairs that follows this rule is A)
Let's check by substituting the values of x = 1, x = 0 and x = -3 into the function:
when x = 1 → -2(1) + 3 = 1
when x = 0 → -2(0) + 3 = 3
when x = -3 → -2(-3) + 3 = 9
Confirming that the set of ordered pairs in A) lie on the graph of the given function.

£810 is divided between Paul, Brian & Colin so that Paul gets twice as much as Brian, and Brian gets three times as much as Colin. How much does Brian get.
Answer:
$486 (Paul)
$243(Brian)
$81(Colin)
Solving steps:
let Paul Be x, Brian be x,Colin be x
since Paul got twice as much as Brian which shows that brian and got three times
So Paul,= 3×2 so he got six times as much as the two others
while Brian got three times
and colins got once
so let's make an equation for this problem
=> 6x + 3x + x = $810
add 6 x + 3 x + x which give you 10 x
=> 10x = $810
divide both side by the coefficient of x
=> [tex] \frac{10x}{10} = \frac{810}{10} [/tex]
=> [tex]x = \frac{810}{10} [/tex]
=> x = 81
since you we have find what the value of x
insert into the previous equation which is
=> 6x + 3x + x
=> 6(81) = $486-----(for Paul)
3(81) = $243-------(for Brian)
(81) = $81 ---------(for Collin)

The amount more in interest over the life of the loan which Nellie have to pay is $14814.
What is bankruptcy?
Bankruptcy is the procedure by which the people who are unable to pay the debts to creditors, may get relief from some or all the debts.
Nellie has a bankruptcy on her credit report and therefore pays higher interest rates on her current loans.
Nellie took out a car loan for $45,000 payable for 6 years at an interest rate of 15%. Thus, the interest is,
[tex]I=\dfrac{45000\times6\times15}{100}\\I=40500[/tex]
If she had not applied for bankruptcy, she would have been able to take out the loan at a rate of 6%. In this case, the interest paid would be,
[tex]I=\dfrac{45000\times6\times6}{100}\\I=16200[/tex]
The difference between the interest paid would be,
[tex]I=40500-16200\\I=24300[/tex]
Hence, the amount more in interest over the life of the loan which Nellie have to pay is $14814.

The gas tank in Enrique's car has 15 gallons of gas. Enrique was able to determine that he can travel 35 miles and only use 2 gallons of gas. At this constant rate, he predicts that he can drive 240 more miles before he runs out of gas. Is he correct? Explain.
Answer:
Yes, he is correct, 240 miles will require a gas volume of 13.71 gallons which is less than 15 gallons in Enrique's car.
Step-by-step explanation:
Given;
total volume of gas in Enrique's car, V = 15 gallons
The rate of gas consumption [tex]= \frac{35 \ miles}{2 \ gallons} = 17.5 \ miles/gallon[/tex]
To drive 240 miles, he would need the following volume of gas;
[tex]V = 240 \ miles* \frac{1}{\frac{17.5 \ miles}{gallon} }\\\\ V = 240 \ miles*\frac{1*gallon}{17.5 \ miles}\\\\ V = (\frac{240 \ miles}{17.5 \ miles} )gallon\\\\V = 13.71 \ gallons[/tex]
The volume of gas needed to drive 240 miles is less than the total volume of gas in Enrique's car.
Thus, he is correct
