Y = a (b^x)

1) x = 0, y = 3500

=> 3500 = a (b^0)

=> 3500 = a (1)

=> a = 3500

2) growth percent = 3.5% => growth rate = 1.035 = b

=> y = 3500 (1.035)^ x

3) year 2020 => x = 2020 - 2000 = 20

4) y = 3500 (1.035)^ 20 = 6964

Answer: 6964.

Answer:

$186.86

Step-by-step explanation:

<u>4 eggs cost:</u>

1 dollar per dozen (12 eggs), so by unitary method (ratios), we can find cost of 4 eggs. Shown below:

\frac{1}{12}=\frac{x}{4}\\12x=4\\x=0.33

So, 4 eggs cost $0.33 approx

<u>12 lb. flour cost:</u>

2.50 dollar per pound, so 12 pounds would simply cost:

2.5 * 12 = $30

<u>14 lb of sugar cost:</u>

4.50 dollar per pound means 14 pounds would cost:

4.5 * 14 = $63

<u>2 ready-made edible flowers cost:</u>

5 cents for each flower means 2 flowers would cost:

5 cent = 0.05 dollars

0.05 * 2 = $0.10

We add all up to find cost of 1 cake. Shown below:

Cost of 1 cake = $0.33 + $30 + $63 + $0.10 = $93.43

Cost of 2 cakes = $93.43 * 2 = $186.86

Can anyone tell me what x equals in this scenario.<br><br> 3/4x=2x-5
Dvinal [7]

Hey There!

The answer to your problem is x=4

<u>Subtract 2x from both sides</u>

<u></u>3/4x-2x=2x-5-2x<u></u>

<u></u>-5/4x=-5<u></u>

<u></u>

<u>Multiply both sides by 4/(-5)</u>

<u></u>(4/-5)*(-5/4)x=(4/-5)*(-5)

A warehouse distributor of carpet keeps 6,000 yards of deluxe shag carpet in stock during a month. The average demand for carpet
Bond [772]

Answer:

The probability that a customer’s order will not be met during a month is 1.67.

Step-by-step explanation:

Given : A warehouse distributor of carpet keeps 6,000 yards of deluxe shag carpet in stock during a month. The average demand for carpet from the stores that purchase from the distributor is 4,500 yards per month, with a standard deviation of 900 yards.

To find : What is the probability that a customer’s order will not be met during a month?

Solution :

Average Mean \mu=4500

Sample Mean x=6000

Standard deviation \sigma=900

The formula is given by,

Z=\frac{x-\mu}{\sigma}

Substitute the value in the formula,

Z=\frac{6000-4500}{900}

Z=\frac{1500}{900}

Z=1.67

The probability that a customer’s order will not be met during a month is 1.67.

<h3>Answer: Choice 2)  sin(B) = cos(90-B)</h3>

Explanation:

The rule is that

sin(A) = cos(B)

if and only if A+B = 90.

Solving for A gets A = 90-B

So we end up with

sin(90-B) = cos(B)

which is the same as

cos(B) = sin(90-B)
