Answer:
$272
Step-by-step explanation:
We're going to make an equation
we'll make x hours
5x=80
solve for x and you get 16 dollars an hour
16 times 17 is 272
Move the variable to one side by finding common denominator
1/4 - 7/10p = 1/20p
5/20 - 14/20p = 1/20p
+ 14/20p +14/20p
5/20 = 15/20p
Simplify
1/4 = 3/4 p
multiply both sides by 4, then divide both sides by 3
1 = 3p
1/3 = p
Answer:
Step-by-step explanation:
Use the basic simple interest formula:
P * r * t = I and put the info into a table with those variables along the top, formig the columns we need:
P * r * t = I
Acct 1
Acct 2
If we have a total of 1500 to split up between 2 accounts, we put x amount of money into one and then have 1500-x left to put into the other. We will fill those in along with the interest rates in decimal form and the time of 1 year:
P * r * t = I
Acct 1 x .04 1
Acct 2 1500-x .05 1
Looking at the formula we are told that Prt = I, so we will multiply P times r times t and fill in the I column:
P * r * t - I
Acct 1 x .04 1 .04x
Acct 2 1500-x .05 1 .05(1500-x)
The total Interest earned by the addition of the interest earned from both accounts is 69.50. So we add the interest column together and set it equal to 69.50:
.04x + .05(1500 - x) = 69.50 and
.04x + 75 - .05x = 69.50 and
-.01x = -5.5 so
x = 550
That's how much money is in the account earning 4% interest.
Answer:
Step-by-step explanation:
- If AB=BC=CA, it means ABC is an equilateral triangle which all three sides are equal.
- Thus, all three internal angles are also congruent to each other and are each 60°.
the circumference of a circle with the radius being 12.5 is C=78.54
