Alja [10]
You will first change the percentage into a decimal. This will turn out to be 0.0975. Next, you take that decimal and do 691.99 times 0.0975. You will then get 67.46902... You then add that number with 691.99. That is the answer. You should get 759.46. (This is rounded to the nearest cent.

Consider the net of a triangular prism where each unit on the coordinate plane represents five feet. If a can of spray paint cov
Lera25 [3.4K]

Answer:

B) 7 cans

Step-by-step explanation:

First task is to determine how many square units we have.

With the rectangle spanning 2 units on the X-axis and 3 unites on the Y-axis, we know that it has an area of 6 square units.

The two triangle shapes sum up to one unit total, since a triangle's area is (base * height) / 2.  Both have a base of 1 unit, and a height of 1 unit... so  (1 * 1) / 2  = 1/2 for each triangle.  Together, they occupy 1 unit.

So, total is 7 square units. Let's imagine it as a 7-unit by 1-unit rectangle, it will be easier to calculate.  Each unit is 5 feet.  So, this rectangle measures 35 (7 * 5) feet long, by 5 (1 * 5) feet wide... for a total of 175 (35 * 5) sq feet.

Since a can of paint can cover 25 sq feet, he'll need 7 cans (175 / 25).

In a survey , rajveer asked 110 people whether they were employed or unemployed.
storchak [24]

Answer:

7

Step-by-step explanation:

Create a two-way table with the given information:

\begin{array}{| c | c | c | c |}\cline{1-4} & \sf Employed & \sf Unemployed & \sf Total\\\cline{1-4} \sf Men & 40 & & 59 \\\cline{1-4} \sf Women & & &  \\\cline{1-4} \sf Total & 84 & & 110 \\\cline{1-4} \end{array}

Fill in the blanks in the table using <u>mathematical operations</u>:

⇒ Men unemployed = 59 - 40 = 19

⇒ Women employed = 84 - 40 = 44

⇒ Total women = 110 - 59 = 51

⇒ Total unemployed = 110 - 84 = 26

⇒ Women unemployed = 51 - 44 = 7

\begin{array}{| c | c | c | c |}\cline{1-4} & \sf Employed & \sf Unemployed & \sf Total\\\cline{1-4} \sf Men & 40 & 19 & 59 \\\cline{1-4} \sf Women &44 & 7& 51  \\\cline{1-4} \sf Total & 84 &26 & 110 \\\cline{1-4} \end{array}

Reading from the table, 7 women responded that they were unemployed.
