Step-by-step explanation:

Given data

let popcorn be x

and drink be y

Mr. Montoya paid $20 for 3 large popcorns and 1 large drink

so

3x+y= 20-------------1

and

Mrs. Cooper bought 3 large popcorns and 3 large drinks and paid $30

so

3x+3y= 30----------------2

solve 1 and 2 above

3x+y= 20

y= 20-3x

put y= 20-3x in eqn 2

3x+3(20-3x)= 30

3x+60-9x= 30

collect like terms

3x-9x= 30-60

-6x= -30

x= 30/6

x= $5

put x= 5 in y= 20-3x

y= 20-3*5

y= 20-15

y= $5

Answer:percent error in Joey's measurement to the nearest 10th of a percent =- 4.6%

Step-by-step explanation:

Step 1

Time as recorded by the stopwatch = 4.82 seconds

Real Time it takes for a Frisbee to fly through the air =5.05 seconds

percent error =   Measured value – True Value /True value  x 100.

= 4.82 - 5.05 / 5.05 x 100

=-0.23/5.05

=-0.0455 x 100

=4.5544%

Rounding to nearest 10th of a percent = - 4.6%

Answer:

x=3

Step-by-step explanation:

Answer:

1. [tex]\frac{(-5k^{2}m)(2km)^{4} (3km^{4}) ^{2}}{k^{2}m^{3}}[/tex] = -720[tex]k^{6}m^{10}[/tex]

2. [tex]\frac{3m}{m^{4} }[/tex] = [tex]\frac{3}{m^{3} }[/tex] (or 3[tex]m^{-3}[/tex])

Step-by-step explanation:

1. The given expression is:

[tex]\frac{(-5k^{2}m)(2km)^{4} (3km^{4}) ^{2}}{k^{2}m^{3}}[/tex]

With respect to the principle of exponential, we have;

[tex]\frac{(-5k^{2}m)(2^{4}k^{4} m^{4})(3^{2}k^{2}m^{8})}{k^{2} m^{3} }[/tex]  = [tex]\frac{(-5k^{2}m)(16k^{4} m^{4})(9k^{2}m^{8} }{k^{2}m^{3} }[/tex]

 Applying the law of indices,              

= [tex]\frac{(-5*16*9)(k^{2+4+2})(m^{1+4+8}) }{k^{2} m^{3} }[/tex]

= [tex]\frac{-720k^{8} m^{13} }{k^{2}m^{3} }[/tex]

= -720[tex]k^{8}m^{13}[/tex] x [tex]k^{-2} m^{-3}[/tex]

= -720[tex]k^{8-2} m^{13-3}[/tex]

= -720[tex]k^{6}m^{10}[/tex]

2. [tex]\frac{3m}{m^{4} }[/tex]

divide the numerator and denominator with common factor m,

= [tex]\frac{3}{m^{3} }[/tex]

This can not be simplified further since there are no more common factors, so that;

[tex]\frac{3m}{m^{4} }[/tex] = [tex]\frac{3}{m^{3} }[/tex] (or 3[tex]m^{-3}[/tex])

Answer:

B. 1, 920

Step-by-step explanation:

To get the median, you order from lowest to highest.

So;

1, 530  ,  1,880  ,  1,920  ,  2,850  ,  2,850

Then you find the middle ground / the number in the middle. Since it's odd, all we have to do is look at the number directly in the middle. So the answer is B. 1, 920.

Answer:

4

Step-by-step explanation:

Answer:

y = 4[tex](2)^{x}[/tex]

Step-by-step explanation:

An exponential function in standard form is

y = a[tex]b^{x}[/tex]

Substitute points from the graph into the equation to find a and b

Using (0, 4 ), then

4 = a[tex]b^{0}[/tex] [ [tex]b^{0}[/tex] = 1 ], so

a = 4

y = 4[tex]b^{x}[/tex]

Using (1, 8 ), then

8 = 4[tex]b^{1}[/tex] = 4b ( divide both sides by 4 )

b = 2

y = 4 [tex](2)^{x}[/tex] ← exponential equation

Answer:

B. 36

Step-by-step explanation:

The pattern is multiplying by 3. You can figure this out by dividing 12 by 4 (which is 3) and 324 by 108 ( which is also 3). Then all you have to do is multiply 12 by 3 which is 36!

Answer:

Cost of one hamburger = $4.25

Step-by-step explanation:

Let,

Cost of one hot dog = x

Cost of one hamburger = y

According to given statement;

6x + 3y = 27.75      Eqn 1

y = x + 1.75             Eqn 2

Putting value of y from Eqn 2 in Eqn 1

6x + 3(x+1.75) = 27.75

6x + 3x + 5.25 = 27.75

9x = 27.75 - 5.25

9x = 22.50

Dividing both sides by 9

[tex]\frac{9x}{9}=\frac{22.50}{9}\\x=2.50[/tex]

Putting x=2.50 in Eqn 2

y = 2.50 + 1.75

y = 4.25

Hence,

Cost of one hamburger = $4.25

Answer:

400 feet

Step-by-step explanation:

real

1 feet = 12 inches

5 feet = 60 inches

scale

3 inches = 20 feet

60 inches=

60/3 = 20

20*20= 400

therefore 5 feet tall equall 400 feet

The actual length of the building will be 400 feet.

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

The scale of the model is,

⇒ 3 inches = 20 feet

Now,

Since, The scale of the model is,

⇒ 3 inches = 20 feet

And, The model is 5 feet tall.

Since, 1 feet = 12 inches

So, 5 feet = 60 inches

Here, The scale of the model is,

⇒ 3 inches = 20 feet

So, The actual length of the building = 60 × 20/3

                                                         = 400 feet

Thus, The actual length of the building = 400 feet.
