I'll give 100 points Devon and his friends bought strawberry wafers for $3 per packet and chocolate wafers for $1 per packet at a carnival. They spent a total of $30 to buy a total of 22 packets of wafers of the two varieties.


Part A: Write a system of equations that can be solved to find the number of packets of strawberry wafers and the number of packets of chocolate wafers that Devon and his friends bought at the carnival. Define the variables used in the equations.


Part B: How many packets of chocolate wafers and strawberry wafers did they buy? Explain how you got the answer and why you selected a particular method to get the answer.

Answer: 840

Step-by-step explanation: 50% is half. All I did was add 420  two time since 420 is half of what this person has to spend.

Answer:

the answer should be 210 dollars because first of all remember that when we are dealing with this problems of percents we need to divide first the percent which is 50% by 100 and you will get 0.50 so then you multiplied it.

0.50 times 420= 210

210 is the correct answer and have a great day.

Answer:

1.) 6

2.) -1

3.) 36

4.) 1/3

5.) 90

Step-by-step explanation:

1.) -12/a

-12/a -> -12/2

=6

2.) a+ (-b)

a+(-b) -> 2+(-3)

=-1

3.) 3a (12-2b)

3a(12-2b) -> 3(2) (12-2x3)

6(12-6)

6(6)

=36

4.) 2a-c/b

2a-c/b -> 2(2)-5/3

4-5/3

=1/3

5.) 3abc

3abc-> 3x2x3x5

=90

Answer:

x=2cm

Step-by-step explanation:

By using pythagoras theorem:

H²=P²+B²

x²=1.6²+1.2²

x=2cm

Answer:

x = 3

y = 1

Step-by-step explanation:

So to solve this by addition we have to add both x's, y's and the numbers on the other side of the equal sign:

x + y = 4

x - y = 2

Both y's will cancel out because we are subtracting y from y

Adding 4 +2 = 6

2x = 6          (adding both x gets 2x)

x = 3

Now that we found x we can find y by plugging it into either equation:

3 + y = 4

y = 1

We can check these in both equations:

3 + 1 = 4        4 = 4

3 - 1 = 2        2 = 2

These answers are then proven correct!

I hope this helps! Good luck!

Answer:

Based on the graph, what is the dependent variable, the equation relating the two variables, and how far will the dragonfly travel in 24 hours if it continues to fly at the same speed?

The dependent variable is time, the equation is y = 22x, and the dragonfly will travel 528 miles.

The dependent variable is time, the equation is x = 22y, and the dragonfly will travel 1,056 miles.

The dependent variable is distance, the equation is y = 22x, and the dragonfly will travel 528 miles.

The dependent variable is distance, the equation is x = 22y, and the dragonfly will travel 1,056 miles.

Answer:

[tex]\boxed{\sf volume = 320 \ ft^3}[/tex]

Explanation:

Volume of triangular prism = 1/2 × Base × Height × Length

Identify the following:

Find Volume:

[tex]Area \: of \: triangle = ½ × height× width \\ area = \frac{1}{2} \times 8 \times \frac{20}{3} \\ area = \frac{{ \cancel8} {}^{ \: \: 4} }{ \cancel2} \times \frac{20}{3} \\ area = \frac{80}{3} {ft}^{2} [/tex]

Now for volume :-

Volume = area of triangle (2D ) × length

[tex]volume = area \times length \\ vol = \frac{80}{3} \times 12 \\ vol = \frac{80}{ \cancel3} \times { \cancel{12}} {}^{ \: \: 4} \\ volume = 320 {ft}^{3} [/tex]

During the first week of her training, she runs 200 meters.  On the second week, she plans to run 50% more.  

Now, how do you calculate this?

To increase 200 meters by 50%, multiply by 1.5

The second week she pans to run 450 meters.

Since there are only 3 weeks, do it again!

The thrid week, she plans to run 675 meters.

Since she runs the same ammount each day of the week, the calculation is simple.

7(200) + 7(450) + 7(675)

In these three weeks, she runs 9275 meters.

OR, she runs 10143.26 yards.

By using the graph, all of the true statements that apply include the following:

B. The variables are dollars and hours.

C. Hours is the independent variable and dollars is the dependent variable.

F. The relationship is y = 3.50x.

In Mathematics and Geometry, a proportional relationship is a type of relationship that produces equivalent ratios and it can be modeled or represented by the following mathematical equation:

y = kx

Where:

Next, we would determine the constant of proportionality (k) by using the various data points from table D as follows:

Constant of proportionality, k = y/x

Constant of proportionality, k = 3.5/1 = 7/2 = 10.5/3

Constant of proportionality, k = 3.50

Therefore, the required linear function is given by;

y = kx

y = 3.50x

Answer:

m = 8

Step-by-step explanation:

turn it into a square and then you can divide 48 by 6 and the answer is 8

Answer:

the answer for the first one is 8 because we need to divide the area which is 48 by 6 to get the answer which is 8 so we multiply  6 times 8 to check if it is 48 and yes sir it is.

In the second one you need to divide 42 by 6 not by 4 and when you do that you get 7 so we multiplied 6 times 7 to check if the area is 42 and yes it is sir again so the first one is 8 and the second one is 7

Step-by-step explanation:

Here, the focus of the parabola is (2,0) and directrix is x=−2.

So, equation of parabola will be y2=4ax

Here,a=2.So, Equation becomes,

y2=4∗2x⇒y2=8x, which is the required equation of parabola.
