In Jude Company, land decreased $150,000 because of a cash sale for $150,000, the equipment account increased $60,000 as a resul
Fofino [41]

Answer:

The net cash provided by investing activities is $90,000

Step-by-step explanation:

In this question, we are asked to calculate the net cash that is provided by investing activities.

To calculate the net cash provided by investing activities, we simply subtract the cash used to purchase equipment from cash from sale of land.

Mathematically, net cash provided by investing activities = cash from sale of land - cash used to purchase equipment.

From the question, we can identify that cash from sale of land is $150,000 while cash used to purchase equipment is $90,000

We substitute these and get; $150,000 -$60,000 = $90,000

A cookie recipe calls for 1 2/3 of sugar if you plan on changing the recipe to make it 2 1/2 times as much how many cups of suga
Dimas [21]

Answer:

4\frac{1}{6}\ cups

Step-by-step explanation:

we know that

The recipe calls for 1 2/3 of sugar

To make 2 1/2 times the recipe

Multiply 2 1/2 by 1 2/3

Convert mixed numbers to an improper fraction

1\frac{2}{3}=\frac{1*3+2}{3}=\frac{5}{3}\ cups

2\frac{1}{2}=\frac{2*2+1}{2}=\frac{5}{2}

so

\frac{5}{2}(\frac{5}{3})=\frac{25}{6}\ cups

Convert to mixed number

\frac{25}{6}=\frac{24}{6}+\frac{1}{6}=4\frac{1}{6}\ cups

The manager of a grocery store wants to determine the average amount of money spent at his store as it compares to the average d
JulijaS [17]
For the manager's store

 Population size: 15
 Arithmetic mean (μ): 37.6
 Standard deviation (σ): 11,056

 For the competitor's store
 
 Population size: 15
 Arithmetic mean (μ): 48,533
 Standard deviation (σ): 28,356

 For the manager's store the average is a better representation of the data since it does not have Outlier points in the box diagram. Also the median is close to the average.

 For the competition store the average of the data collected is not as good representation of the data since they are dispersed from the mean with a standard deviation of 28.35. It also presents Outliers points in the box diagram, such as 112 which is very far from the average

For the given expression, which whole number (w) will make the expression true? 5/6
Sonja [21]

Answer:

D. 7

Step-by-step explanation:

The question is incomplete. Here is a possible complete question

For the given expression, which whole number (w) will make the expression true? 5/6 < w/6

A. 3

B. 4

C. 5

D. 7

Given the inequality expression:

5/6 < w/6

Cross multiply

5×6 < 6×w

30<6w

Divide both sides by 6

30/6 = 6w/6

5<w

Reciprocate both sides(this will change the sense of the inequality)

1/5>1/w

Cross multiply

w > 5×1

w>5

This shows that the value of w is a value greater than 5 but not 5. According to the option, the only value greater than 5 is 7. Hence the whole number (w) that will make the expression true is 7
