Question 5

Vikentia [17]

The amount of sales (S) of statin in billions of dollars by 2017 is 34.5 billions

<h3>Linear equations</h3>

Linear equation are equation that has a leading degree of 1. Given the equation that represents Statins used to keep cholesterol in check and are a top-selling drug in the U.S.

S-1.5x = 6

where

S is the amount of sales

x is the number of years after 1998

By 2017, the total number of years is 19 years

Substitute

S = 1.5x + 6

S = 1.5(19) + 6

S = 28.5 + 6

S = 34.5

The amount of sales (S) of statin in billions of dollars by 2017 is 34.5 billions

A candle burned at a steady rate. After 33 minutes, the candle was 11.2 inches tall. Eighteen minutes later, it was 10.75 inches

Amiraneli [1.4K]

Answer:

9.025 inches

Step-by-step explanation:

Let the length be represented by:

$L = mt+L_0$

Where $L$ is the length of candle at time $t$

$m$ is the rate at which the candle is burning.

And $L_0$ is the initial length of the candle.

As per the question statement, let us put the given values in the equation.

$11.2 = m\times 33 + L_0 .... (1)\\10.75 = m\times 51+L_0 ..... (2)$

Subtracting (1) from (2):

$0.45 = -18m\\\Rightarrow m = -0.025$

Putting the value of $m$ in the equation (1):

$11.2 = -0.025 \times 33+L_0\\\Rightarrow L_0 = 12.025$

Therefore, the equation becomes:

$L = -0.025t + 12.025$

Now, we have to find the height of candle after 2 hours.

2 hours mean 120 minutes.

$L = -0.025 \times 120 + 12.025\\\Rightarrow L = 9.025\ inches$

Therefore, the height of candle is <em>9.025 inches</em>.

Solve for x: 10x – 3 + x < 30

Gala2k [10]

Answer:

The correct answer would be the last one; x < 3.

Step-by-step explanation:

Step 1: Simplify both sides of the inequality.

11x - 3 < 30

Step 2: Add 3 to both sides.

11x - 3 + 3 < 30 + 3

11x < 33

Step 3L Divide both sides by 11.

11x/11 < 33/11

Therefor, the correct answer would be the last one: x < 3

Hope this helps!
