Answers

Answer:

See below

Step-by-step explanation:

Part A: For the current year, we notice that the price of corn is directly proportional to the number of bushels at a rate of $8 per bushel. We know this because 2 bushels * $8 = $16, 4 bushels * $8 = $32, and so on.

Part B: The rate for the previous year is $6 per bushel, so the current year rate is $2 more than the rate for the previous year

The answer is x=6, have a good day!

Answer:

[tex]x=6[/tex]

Step-by-step explanation:

First let's put our equation

[tex]14+(5x-7)=19+3x[/tex]

Let's drop our parenthesis

[tex]14+5x-7=19+3x[/tex]

Subtract 3x from both sides

[tex]14+2x-7=19[/tex]

Simplify

[tex]7+2x=19[/tex]

Subtract 7 from both sides

[tex]2x=12[/tex]

Divide both sides by 2

An account with an initial balance of $4000 earns 6.5% interest for 5 years.
What is the ending balance?
Enter your answer in the box. $.

Answers

Answer:

The balance in the bank after 5 years of 6.5% interest is $5,300.

Step-by-step explanation:

*Presuming that this is not a compounding interest the interest would just multiply by the even balance.*

So every 5 years the balance earns 0.065 of 4,000 dollars.

This would make our equation:

4000 + (4000 x .065 x 5 )

= 4000 + (1300)

= 5300

The balance in the bank after 5 years of 6.5% interest is $5,300.

Answer:

5,300

Name the missing coordinate(s) of each triangle

Answers

Answer:

13) C (a, a) Y (a, 0)

14) B (0, b) P (a, 0)

Step-by-step explanation:

13) Y lies on x axis so it is Y(a,0)

ZY = YC = a

so for C coordinates are (ZY,YC) = (a, a)

14) B lies on y axis so it is B(0, b)

BK = BP = [tex]\sqrt{a^{2} + b^{2} }[/tex] = distance between two points

so P is (a, 0) as it is same distance and on positive side of x axis

13- C (a,a) Y (a,0)
