a 15 foot building casts a 9 foot shadow. How tall is the building that casts a 30 ft shadow at the same time

1 answer:

4 0

9 + 9 = 18 + 9 = 27. 1/3 of 9 is 3 27 + 3 = 30
15 x 3 = 45. 1/3 of 15 is 5. So, 45 + 5 = 50.
The building is 50 feet tall.

What is a whole number between the square root of 27 and the square root of 39

Vinvika [58]

That number would be 6.
Since 5^2 = 25 and 6^2 = 36, we can see that the only possible whole number between sqrt(27) and sqrt(39) has to be 6.

Michael earns $900 per month, plus 5% commission on all his sales over $750. what is the minimum amount of sales Michael must ha

Alina [70]

<h3>The minimum amount of sales Michael must have to earn at least $2500 in a month is $ 32000</h3>

Solution:

The expression to Michael earnings is:

$b + (c \times s)$

Where,

b is the base salary, which is $ 900 in this sum

c is the commission rate

Given that commission rate is 5%

s is the sales

Michael must have to earn at least $2500 in a month

Here, at least means, "greater than or equal to" 2500

The inequality is framed as:

base salary + 5 % on sales $\geq$ 2500

$900 + \frac{5}{100} \times s \geq 2500\\\\\ 900 + 0.05s\geq 2500$

Solve the inequality

$0.05s\geq 2500-900\\\\0.05s \geq 1600\\\\Divide\ both\ sides\ by\ 0.05\\\\s\geq 32000$

Thus, minimum amount of sales Michael must have to earn at least $2500 in a month is $ 32000
