QUESTION POSTED AT 14/12/2019 - 05:14 PM

The answer is 137.5

How?

You must change 40% into a decimal by multiplying 100. ⇒ 0.40

Next, divide it. 55 ÷ 0.40.

55 ÷ 0.40= 137.5

Hoped this helped.

Ok so the numbers are in a sequence of +3 so he would go 2,5,8,11,14. He could only have 5 groups of marbles because 2+5+8+11+14=40

**Answer:**

**The number –55 is an integer.**

**Step-by-step explanation:**

Consider the provided information.

**Whole numbers are the numbers 0, 1, 2, 3, 4, 5,...**

**Natural numbers are the numbers 1, 2, 3, 4, 5,...**

**Integers are the whole numbers, but they include negative numbers ...-5,-4,-3,-2,-1,0,1,2,3,4,5..**

**Irrational numbers are numbers which are not expressible as a ratio of two integers.**

Now consider the provided number –55.

From the above definition the number –55 is neither whole number nor the natural number. Also –55 is not an irrational number because it can be expressible as a ratio of two integers.

**Hence, the number –55 is an integer.**

Given the function f(x) = 0.11x + 43, this shows the relationship between how much Derek has to pay for phone service for the amount of minutes he uses on international calls a month.

f(320) can be solved by substituting x = 320, and this is shown below:

f(x) = 0.11x + 43

f(320) = 0.11(320) + 43

f(320) = 78.2

This means that Derek has to pay $78.20 for the 320 minutes of calls. Among the choices, the correct answer is B.

It is useful to start by drawing a picture to visualize this problem.

In this case we are going to use the trigonometric function cosine, which is Cos(theta) = adjacent / hypotenuse.

Cos(55) = 40 / x

After simplifying we reach the equation: X = 40 / cos(55)

which would then make the length of the wire 69.7 meters long.

The graph is an exponential function with y-intercept of 9600. The curve goes upward indefinitely as the value of time increases.

Therefore, from the choices, the statements that apply to the graph are:

-The graph of the function begins at y = 96,000.

-The graph of the function shows the exponential growth.

If the range of the numbers in the list L is 4, then x can't be 4 since there is an element in the list that is x^2. Therefore,

0 ≤ x^2 ≤ 4 so that it would be the highest number and

0 ≤x ≤ 2

So, the value of x can be equal to 2 but not higher. So, 2 is always greater or equal to x.

**Answer:**

D. The expression is . It takes 40 minutes to shape and fire 10 pots.

**Step-by-step explanation:**

Let the number of pots in a batch = p

Now, one pot takes 3 minutes to get in a shape.

Then, 'p' pots will take minutes to get in a shape.

Also, it takes 10 minutes to fire one batch of pots.

**Thus, the expression for the time taken to form one batch of pots = **

So, when number of pots = 10 i.e. p= 10.

Time taken to fire the pots = = 30+10 = 40

**That is, 'It takes 40 minutes to shape and fire 10 pots'.**

Thus, option D is correct.
