True [87]

Answer:

B

Step-by-step explanation:

The question is:

<em>What percent of time did Nik spend with clients on Thursday? </em>

<em>a. 10% </em>

<em>b. 70% </em>

<em>c. 30 % </em>

<em>d. 80%</em>

<em />

<u>Solution:</u>

c means client meetings and o means other work.

The hours are shown in the table.

We want % of time on Thursday that he spent on clients.

In Thursday:

7c and 3o

Means 7 hours with clients and 3 hours with office work.

Total time spent = 7 + 3 =  10 hours

Client time spent = 7 hours

% time spent with clients on Thursday: 7/10 = 0.7 * 100 = <u>70%</u>

<u>Answer choice B is right.</u>

For the following problem state the objective function and the constraints. DO NOT solve:
Mama L [17]

Answer:

If we define S as the number Sprinkle's umbrellas, and H as the Hurricane's umbrellas, the profit P can be expressed as:

P=3S+5H

The restriction for cloth can be written as:

S+2H\leq500

The restriction for metal can be written as:

2S+3H\leq600

The restriction for wood can be written as:

4S+7H\leq800

The condition for S and H to be positive is:

S, H \geq0

Step-by-step explanation:

We have an objective function that, in this case, we want ot maximize.

This function is the Profit (P).

If we define S as the number Sprinkle's umbrellas, and H as the Hurricane's umbrellas, the profit can be expressed as:

P=3S+5H

We have 3 restrictions, plus the condition that both S and H are positive.

The restriction for cloth can be written as:

S+2H\leq500

The restriction for metal can be written as:

2S+3H\leq600

The restriction for wood can be written as:

4S+7H\leq800

The condition for S and H to be positive is:

S, H \geq0

a yard width is 2 less than it's length. If the perimeter of the yard is 20 feet determine the length and the width of the yard
Arte-miy333 [17]

Answer:

The length is 6 feet and the width is 4 feet

Step-by-step explanation:

Let x represent the length of the yard

The width can be represented by x - 2, since it is 2 less than the length.

Use the perimeter formula, P = 2l + 2w, where l is the length and w is width

Plug in the expressions and perimeter:

20 = 2x + 2(x - 2)

Solve for x:

20 = 2x + 2x - 4

20 = 4x - 4

24 = 4x

6 = x

So, the length is 6. Plug this into x - 2 to find the width

x - 2

6 - 2

= 4

So, the length is 6 feet and the width is 4 feet
