How would you solve this?

Answers

Answer:

For the equation, you should subtract 2x on both sides to get -y = -2x - 4.  Flip the y's negative sign to get a proper function which is y = 2x + 4.  The y-intercept is at (0, 4) and each unit will move two units up along the x-axis.

A person invests 3000 dollars in a bank. The bank pays 4.25% interest compounded semi-annually. To the nearest tenth of a year, how long must the person leave the money in the bank until it reaches 5600 dollars?

Answers

Answer:

The person must leave the money for approximately 14.8 years.

Step-by-step explanation:

This can be calculated using the formula for calculating the future value as follows:

FV = PV * (1 + r)^n …………………………………. (1)

Where;

FV = Future value of the investment = 5600

PV = Present value of the investment = 3000

r = semiannual interest rate = 4.25% / 2 = 0.0425 / 2 = 0.02125

n = number of semiannuals = ?

Substitute the values into equation (1) and solve for n, we have:

5600 = 3000 * (1 + 0.02125)^n

5600 / 3000 = 1.02125^n

1.02125^n = 1.86666666666667

Loglinearizing both sides, we have:

nlog1.02125 = log1.86666666666667

n = log1.86666666666667 / log1.02125

n = 0.271066772286539 / 0.0091320695404719

n = 29.6829509548973

Since n is number of semiannuals, we divide the answer by 2 obtain the number of years as follows:

Number of years = 29.6829509548973 / 2 = 14.8414754774487

Rounding to the nearest tenth of year, we have:

Number of years = 14.8

Therefore, the person must leave the money for approximately 14.8 years.

Christine's middle school total of 900 students and 45 teachers. The local high school has 110 teachers and a student-teacher ratio propotional to the middle school's. How many students find when she gets to high school

Answers

Answer:

2,200

Step-by-step explanation:

From the above, we were given that;

Total students in Christine's middle school = 900

Teachers in Christine's middle school = 45 teachers

Local high school = 110 teachers

Then, we can write an equation ratio and solve it.

900 students / X = 45 teachers / 110 teachers

If we cross multiply, we'll get

900 × 110 = 45 × X

45X = 99,000

Divide both sides by 45

45X/45 = 99,000/45

X = 2,200

Therefore, Christine would find 2,200 students when she gets to high school.

Martha estimated there were 91 marbles in a jar for a contest. The actual number of marbles in the jar was 113. What was the percent error of Martha's estimation?
A. 24.18%
B. 80.53%
C. 22%
D. 19.47%

Answers

Answer:

D. 19.47

Step-by-step explanation:

91/113 = 80.53

100.00-80.53 = 19.47

Answer:

19.47% to the nearest hundredth.

Step-by-step explanation:

Value of the error = 113 - 91 = 22.

Percent error = (22/113) * 100

= 19.47.

What is the unitary method?

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Given that, a wheel makes 35 revolutions per min.

Here,

35/1 minute × 1 minute/60 seconds

= 35/60

= 7/12 revolution per second

Therefore, the wheel makes revolutions per second is 7/12.

Mr. Demers is making a drink by adding flavor drops to his water. If he puts 3 drops in a 12 ounce glass of water, how many ounces does he use PER DROP?

Answers

Answer:

Step-by-step explanation: if he puts 3 drops in a 12 ounce glass of water he should be using 4 ounces per drop 12 ounces divided by 3 drops gives you 4 ounces per drop

Answer: 4 ounces per drop

=======================================================

Explanation:

"Per drop" means "per 1 drop" or "for each 1 drop".

We start off with the ratio of

3 drops: 12 ounces

Divide both parts of that ratio by 3 so that "3 drops" turns into "1 drop"

Doing so gets us the new ratio of

1 drop: 4 ounces

So he uses 4 ounces per drop.
