Answer:

See the graph.

Step-by-step explanation:

The function that represents the problem is

f(x) = {15 if 1≤x≤5 and 15+1.50(x-5) if x>5

and the graph is in the image, the green line is in y=15. You need to be clear that x takes integer values, but the graph shows a continuous function.

Notice the picture, after the price of quantity (x) of 5, the price begins to slant up, but before 5 is just a straight line, a steady price of 15
\bf f(x)=
\begin{cases}
15,&0\ \textless \ x\le 5\\\\
1.5x+7.5,&x\ \textgreater \ 5
\end{cases}

Answer:

A.  6 and 30

B.  8 and 28

Step-by-step explanation:

we know that the area of the three squares must satisfy the Pythagorean Theorem so c² = a² + b²

where

c²  is the area of the largest square

a² and b² are the areas of the smaller squares

now.. 36² = a² + b2

The sum of the areas of the smaller squares must be equal to 36

therefore

6 and 30 >>>> could be the areas of the smaller squares (6 + 30 = 36)

8 and 28 >>>> could be the areas of the smaller squares (8 + 28 = 36)

hope it clears your mind.

The label on a can of lemonade gives the volume as 12 fl oz or 355ml . Verify that these two measurements are nearly equivalent
liraira [26]

We have been given that the label on a can of lemonade gives the volume as 12 fl oz or 355 ml and we are asked to verify that these two measurements are nearly equivalent.

Since we know that 1 fluid ounce equals 29.5735 ml. Let us find volume of lemonade can in ml by multiplying 12 by 29.5735.

\text{Volume of can}=12\cdot29.5735

\text{Volume of can}=354.882

\text{Volume of can}=354.882\approx355

We can see that 354.882 is nearly equivalent to 355. Therefore, we can say that these two measurements are nearly equivalent.

Three different members of the set {4,5,6,7,8,9} are chosen at random and added. How many different sums are possible?
Aloiza [94]

Answer:

10

Step-by-step explanation:

4+5+6=15,

4+5+7=16,

4+5+8=17,

4+5+9=18,

4+6+7=17,

4+6+8=18,

4+6+9=19,

4+7+8=19,

4+7+9=20,

4+8+9=21,

5+6+7=18,

5+6+8=19,

5+6+9=20,

5+7+8=20,

5+7+9=21,

5+8+9=22,

6+7+8=21,

6+7+9=22,

6+8+9=23,

7+8+9=24.

There are sums 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 10 different sums in total.
