Answer:the number of hot dogs that were sold is 11

the number of hamburgers that were sold is 16

Step-by-step explanation:

Let x represent the number of hot dogs that were sold.

Let y represent the number of hamburgers that were sold.

At a snack stand, hot dogs cost $3.50 and hamburgers cost $5. If the snack stand sold 27 snacks and made $118.50 in revenue, this means that

x + y = 27 - - - - - - - - - -1

3.5x + 5y = 118.5 - - - - - - - 2

Substituting x = 27 - y into equation 2, it becomes

3.5(27 - y) + 5y = 118.5

94.5 - 3.5y + 5y = 118.5

- 3.5y + 5y = 118.5 - 94.5

1.5y = 24

y = 24/1.5 = 16

x = 27 - y = 27 - 16 = 11

Use the table of reciprocals to find the reciprocal of these numbers:<br> 0.000 080 25 <br> 0.9596
Licemer1 [7]

Answer:

1000000/8025 = 40000/321 (simplified)

1000/9596

Step-by-step explanation:

Hi there,

There is an alternative way to do this....

First it is important to understand what a reciprocal is. The reciprocal of any number x is the number 1/x. The reciprocal of a number is also its multiplicative inverse, which means that the number times its reciprocal must equal 1. For a number such as 2, the reciprocal would be 1/2. For a fraction such as 2/5, the reciprocal would be 5/2.

Finding the reciprocal of a decimal can be done in a number of ways.

Change the decimal to a fraction first.

Ex. 0.25 is 25/100 and is equivalent to the fraction 1/4. Therefore Its reciprocal would be 4/1 or 4.

Keep the decimal and form the fraction 1/?? which can then be or converted to a decimal.

Ex. 0.75 The reciprocal is 1/0.75. Using a calculator, the decimal form can be found by performing the operation: 1 divided by 0.75. The decimal reciprocal in this case is a repeating decimal, 1.33333....

After finding a reciprocal of a number, perform a quick check by multiplying your original number and the reciprocal to determine that the product is 1:

(0.25)(4) = 1.00

(0.75)(1.33....) = 1 but it is easier to see for sure with repeating decimals if you use the fractions instead of the decimals.

(3/4)(4/3) = 12/12 = 1

Hope this helps, Mark as brainliest if liked it! thanks!

A regular hexagon is rotated 360° about its center. How many times does the image of the hexagon coincide with the pre image dur
lianna [129]

The image of the regular hexagon coincides with the pre-image 6 times during rotation.

A regular hexagon is a polygon that has six equal sides and six equal angles.

In a single rotation which is usually the rotation of an object at 360°, the number of times in which the regular hexagon coincides with its pre-image is 6 times, this is because it has 6 equal sides and 6 equal angles.

Devon made a scale drawing of a triangle. He used a scale factor of 1/4 to draw the new triangle. How does each side of the new
Charra [1.4K]
The answer is Option A.
Scale Factors
If the Scale Factor IS 1, the polygon stays the SAME.
(If an equilateral triangle has a side length of 8 and the scale factor is 1, the sides will stay at 8)
If the Scale Factor is MORE THAN 1, the polygon's sides INCREASE depending on what the scale factor is.
(If a square has a side length of 3 and the scale factor is 4, the sides will increase to 12)
If the Scale Factor is LESS THAN 1, the polygon's sides DECREASE depending on what the scale factor is.
(If a square has a side length of 5 and the scale factor is 1/2, the side lengths will decrease down to 0.5)
Therefore each side length of the new triangle is 4 times shorter than the original (Option A)
