We can use logic along with 3 linear equations to solve this problem.

For the three types of candies, we will write a slope-intercept form equation. We know what m (slope) is for each equation, and there is no y-intercept because there is no starting point.

Equations:

Mints: y=.96x
Chocolates: y=4.70x
Lollipops: y=.07x

Using the given information, we can use the equations in function form. We know what x (input) is for all three types of candy, and that will give us y (output), which is the total for that candy type.

Solving:

Mints: y=.96(.75)
Chocolates: y=4.70(1.5)
Lollipops: y=.07(15)
We just input our information into the equations. Using logic, we know that we will have to multiply the cost of the candy by the number of candies to get the total of the three types.

Totals:

Mints: y=.72
Chocolates: y=7.05
Lollipops: y=1.05.
*Recall that y=total cost of candy for each type.

Now, we just simply add the three costs up to get the total sum that the candy will cost:

.72+7.05+1.05=8.82

Therefore, all the candy will cost $8.82.

Marcia has a licorice rope that is 28 inches long. She wants to cut it into 3,-inch pieces to share with friends. How many piece
diamong [38]

Answer:

9 pieces

Step-by-step explanation:

28 inches rope cut into 3-inch pieces

  • 28/3 = 9 1/3

There is no matching answer choice, if given numbers are correct then the answer is 9 full pieces

---------

<u>Note:</u>

  • The close answer choice is 8
  • 28/8 = 3 1/2 or 3.5
  • So if cut into 3.5 inch pieces then it is 8 full pieces
  • just in case it was typo 3 instead of 3.5

the sum of two numbers is 104. the larger is one less than twice the smaller number. find the numbers
exis [7]

Answer:

The larger number is 69 and the smaller number is 35.

Step-by-step explanation:

Find the equations. Here x will be the larger number and y will be the smaller number.

x + y = 104

x = 2y -1

Substitute:

(2y -1) + y = 104

3y = 105

y = 35

x = 2(35) - 1

x = 70 - 1

x = 69

The larger number is 69 and the smaller number is 35.

The average weight of full-grown beef cows is 1,470 pounds with a standard deviation of 230 pounds. if the weights are normally
creativ13 [48]

Answer: The percentile is 89

Step-by-step explanation:

This question can be solved using concept for t tables

In a normal distribution the curve. \mu= 1470 ,  \sigma = 230, x=1750

The relationship between z score, mean and standard deviation is given by

x = \mu+z\sigma

So the z value according to this is given by the formula

1750=1470+z(230)\\ z=\frac{280}{230} \\\\z = 1.217

From the z table we can infer that p value for z=+1.217 is 88.82

So 1750 is 89th percentile
