Julie's savings account has a balance of $57.85 in January. By March, her balance is 4 times as much as her January balance. Between March and November, Julie deposits a total of $78.45. If she does not withdraw any money from her account, what should Julie's balance be in November?

Answers

Answer 1
Answer: January . . . $57.85

March . . . . 4 times as much = 4 (57.85) = $231.40

Deposit  78.45 more . . . ($231.40 + 78.45) = $309.85 .

Notice that "interest" is never mentioned anywhere in this problem.
In other words, it doesn't matter whether Julie's savings account is
in a bucket in the basement, a mayonnaise jar on the porch, under
her mattress, or in a bank that pays no interest.

Without interest, $309.85 is what she does have in November, which
is about right for savings accounts in banks these days.

What her balance should be in November is an entirely different subject.

Write the rate 1/7 inch----------------- as a unit rate
1/14 minute

Answers


1/7in=1/14min

14/7in=min

2in=min

The rate is 2 inches per minute

Final answer:

The unit rate for the given problem, 1/7 inch per 1/14 minute, is calculated by dividing the inches by the minutes. This simplifies to 2 inches per minute.

Explanation:

In mathematics, a unit rate is a rate in which the second number (or denominator) is one. When you are asked to write the rate 1/7 inch per 1/14 minute as a unit rate, you are being asked to find a rate that tells you how much of each quantity occurs for each single unit of the other quantity, in this case for 1 minute. To calculate this unit rate, divide the quantity in inches by the quantity in minutes.

In this problem, you can find the required unit rate by dividing (1/7) by (1/14), which simplifies to (1/7) * (14/1) = 2 inches. So, the unit rate for this problem is 2 inches per minute.

What's 16.6666667 to the nearest tenth 

Answers

16.7 is the answer rounded to the nearest tenth.

Final answer:

The number 16.6666667 rounded to the nearest tenth is 16.7. Rounding is done by looking at the number to the right of the digit you're rounding to; if it's 5 or more, you round up.

Explanation:

The student is asking about rounding the number 16.6666667 to the nearest tenth. Rounding is used to make a number easier to work with. In this case, we will be rounding to the tenth place, which is one decimal place to the right of the decimal point.

The number in the tenth place here is 6. The number to its right is also 6. When the number to the right of the digit you are rounding to is 5 or more, you round up. Therefore, 16.6666667 rounded to the nearest tenth is 16.7.

The quadratic $-6x^2+36x+216$ can be written in the form $a(x+b)^2+c$, where $a$, $b$, and $c$ are constants. What is $a+b+c$?

Answers

Answer:

-47

Step-by-step explanation:

Step 1: Factor GCF

-6(x² - 6x - 36) = 0

Step 2: Divide by -6 on both sides

x² - 6x - 36 = 0

Step 3: Isolate x's

x² - 6x = 36

Step 4: Complete the Square

x² - 6x + 9 = 36 + 9

(x - 3)² = 45

Step 5: Move everything to one side

(x - 3)² - 45 = 0

So, a = 1, b = -3, c = -45

1 - 3 - 45 = -47
