Answer:

$d=14.5$

Step-by-step explanation:

Given equation:

$d - 10 - 2d + 7 = 8 + d - 10 - 30$

To solve the equation for 'd', take the terms of 'd' to one side and the constants to the other side.

$d - 2d - d = 8 - 10 - 30- 7+10$

$-2d=8-30-7\\-2d=1-30\\-2d=-29\\ d=\frac{29}{2}\\ d=14.5$

On, solving the equation the value of 'd' is $d=14.5$

Sixty seven percent of the employees in a company have managerial positions, and 58 percent of the employees in the company have

Kazeer [188]

Answer: The proportion of employees who either have MBAs or are managers are 0.58.

Step-by-step explanation:

Since we have given that

Probability of employees having managerial positions = 67%

Probability of employees having MBA degrees = 58%

Probability of managers having MBA degrees = 67%

So, using probability formulas, we get that

$P(A\cup B)=P(A)+P(B)-P(A\cap B)\\\\P(A\cup B)=0.67+0.58-0.67\\\\P(A\cup B)=0.58$

Hence, the proportion of employees who either have MBAs or are managers are 0.58.

What’s the answer to this problem?

Allisa [31]

We can start to solve this problem by using what we know. The recipe calls for 2/3 cup of flour per 1/4 batch of cookies. Now, If we want to write the rate as a complex fraction, we can replace the per with a division sign. This makes it become (2/3)/(1/4) or
$\frac{ \frac{2}{3} }{ \frac{1}{4} }$

Of all the species in the world, 4 out of every 5 are insects what percentage of species are insects

Fiesta28 [93]

Answer:

80%

Step-by-step explanation:

So you basically, just make it a ratio. Since a percentage is out of 100, just make the 5 into 100. To get 5 to 100, you times 20. Then you do the same thing to the 4 which you get 80.

Marc is running 5 kilometers at track practice. He decides to break the run into 3 equal lengths. How long will each length be?

MrMuchimi

Divide 5 by 3.
If you do this on a calculator you will get 1.666666667.
You will then round that to 1.7
Because "4 or less let it rest, 5 or more raise the score"
