Explanation:

The data from the stem-and-leaf plot is:

10,

24,25,26,

30,30,32,33,

40,45,46

Add up those values

10+24+25+26+30+30+32+33+40+45+46 = 341

Then divide over n = 11 which is the sample size.

341/11 = 31 is the arithmetic mean.

Answer:

341/11 = 31 is the arithmetic mean.

draw a line that makes a triangle and rectangle.

hypotenuse= 30

3k-4k-5k triangle

18-24-30

so the short part of triangle is 18 cm

10+10+18+24+30 equals 92

sorry for language I am not familiar with English

the perimeter of this shape is

24+10+10+30+\(\sqrt{30^{2} -24^{2} }\) = 92 cm

Answer:

D is the right choice and no you cannot fit the pizza inside the box.

Step-by-step explanation:

D is the answer because to turn 2/3 into a decimal you would divide 2 by 3 and the answer you would get would be 0.66666666666...You would then add 12 to the answer and get 12.6666... Once you get this answer you would round it to the hundredths to get 12.67 but since that is not an option you could use D, 12.66 inches.

Answer:

I believe the answer is D.

15 square units is the area of the irregular polygon

The value of A/B is given as follows:

A/B = -2.

From the graph, the function has a vertical asymptote at x = 1, hence the value of B is given as follows:

B = -1 -> as x + B = 0 -> x = -B = -1.

When x = 0, y = -2, hence the value of A is obtained as follows:

A/-1 = -2

A = 2.

Then the division is given as follows:

A/B = 2/-1 = -2.

Step-by-step explanation:

1, 1/2=2/4, 2/4+(-1/4)= 1/4

2, -10.28+(-5.34)= -15.62

3,  -6/10= -12/20, 3/4= 15/20, -12/20+15/20= 3/20

Step-by-step explanation:

Answers:

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

Let,

x = number of pounds of chocolate

y = cost of buying x pounds of chocolate

If you buy x = 2 pounds, then you spend y = 9.98 dollars.

So k = y/x = 9.98/2 = 4.99 is the cost per pound. This is known as the unit price or unit cost. It's the cost of one pound of chocolate.

Now if you buy x = 5 pounds, then you'll be charged a total of y = 24.95

So, k = y/x = 24.95/5 = 4.99

We get the same constant of proportionality here, and therefore, this is a direct proportional relationship. Each time x goes up by 1, y goes up by 4.99; in other words, each time you buy 1 extra pound of chocolate, you pay $4.99 more. This is to be expected whenever you're at the grocery store as long as you ignore things like coupons or bulk discounts or things of that nature.

The equation of this line is y = 4.99x

This shows the slope is 4.99 and the y intercept is 0.

------------------

An alternative approach:

Again we define x and y as stated above. We see that the two points are (2,9.98) and (5,24.95)

Computing the slope gets us

m = (y2-y1)/(x2-x1)

m = (24.95-9.98)/(5-2)

m = 14.97/3

m = 4.99

So this matches what we got earlier.

Now turn to y = mx+b. Plug in that value of m along with (x,y) = (2,9.98)

Doing so gets us 9.98 = 4.99*2+b

Let's solve for b

9.98 = 4.99*2+b

9.98 = 9.98+b

0 = b

b = 0

I subtracted 9.98 from both sides to isolate b. The fact we get the y intercept is 0 helps show that we have a direct proportion. All direct proportion linear equations go through the origin (0,0). This is to reflect that buying 0 pounds of chocolate means you pay 0 dollars.

We get the same result as the previous section.

Answer: Answer: C. 3.2 × 10^4

Step-by-step explanation: for this case the multiplication of the values with exponent are summed, as the exponent are the 6 and -3

6 - 3 = 3

this will be the exponent of the common value which is the 10.

after you only need to multiply 8 and 4 by separate the

8 * 4 = 32.

then we only need to place the values one by one

32 × 10^3

3 is the result of the sum of the exponent.

10 is the common value.

32 is the result of the product.

if we add another zero to the multiplication we get 3.2 and exponent finish with one more zero, then we get this result

3.2 × 10^4

because of that the C is the correct answer, keep in mind that the other answers do not apply correctly the rule of the exponent, because the rest of answer give us wrong answer with final result of the exponent.

2x is added with 9

Answer:

20 nickels, 40 dimes, and 8 quarters

Step-by-step explanation:

This is a system of three equations with three unknowns. Let x = # of nickels, y = # of dimes, and z = # of quarters.

x + y + z = 68 (since there are 68 total coins)

.05x + .10y + .25z = 7

.10x + .05y + .25z = 6 (if the nickels were dimes and the dimes were nickels)

Multiply both sides of the last two equations by 100 to simplify, giving us:

5x + 10y + 25z = 700 or x + 2y + 5z = 140 if you divide both sides by 5.

10x + 5y + 25z = 600 OR 2x + y + 5z = 120 if you divide both sides by 5.

Let's solve the first equation for x. That gives us x = 68 - y - z. We can substitute this result into each of the final two equations to create a system of two equations with two unknowns, which is easier to solve. For the first equation:

(68 - y - z) + 2y + 5z = 140

68 + y + 4z = 140 or y + 4z = 72

For the second equation, we have:

2(68 - y - z) + y + 5z = 120

136 - 2y - 2z + y + 5z = 120

136 - y + 3z = 120

-y + 3z = -16

Now we have our system of two linear equations:

y + 4z = 72

-y + 3z = -16

If we add those two equations together, then we get 7z = 56 or z = 8. If z = 8, we can substitute this into either of the two previous equations. Let's choose the first. This gives us:

y + 4(8) = 72 or y + 32 = 72.

So y = 40. If y = 40 and z = 8, then we know:

x = 68 - y - z = 68 - 40 - 8 = 28 - 8 = 20.

Consequently, there were 20 nickels, 40 dimes, and 8 quarters in the piggy bank.
