Answer:

6s + 8c ≥ 900

Step-by-step explanation:

The library has <em>at least</em> 900 square feet available. It means <em>900 or more</em>.

If s is the number of study cubicles and c is the number of computer stations, the total space occupied by them is 6s+8c. That space is 900 or more square feet, so our inequality is 6s + 8c ≥ 900

Nate has an account that pays 2. 76% simple interest per year and wants to accumulate $3,090 in interest from it over the next 1

lana66690 [7]

We have given that,

interest rate = 2.76%

simple interest = 3,090

term = 15 years

<h3>What is the principle of simple interest?</h3>

$Simple Interest = Principal * interest rate * term$

$3,090 = Principal * .0276 * 15\\3,090 = Principal * 0.414\\3,090 / 0.414 = Principal\\7,463.77 = Principal$

Therefore,Nate should invest 7,463.77 to meet his goal.

HELPPPPPPPPP i have the most trouble with math what’s the answer??

lakkis [162]

Answer:

Second Option

$\frac{5\sqrt{11} +5\sqrt{3}}{8}$

Step-by-step explanation:

To simplify the expression you must multiply the numerator and the denominator of the fraction by the conjugate of the denominator.

If you have an expression of the form

$a -b$ then its conjugate will be $a + b.$

The result of that multiplication will be

$a ^ 2 -b ^ 2$

Therefore we have the expression

$\frac{5}{\sqrt{11} -\sqrt{3}}$

By multiplying by the conjugate of the denominator we have

$\frac{5}{\sqrt{11} -\sqrt{3}}*\frac{\sqrt{11} +\sqrt{3}}{\sqrt{11} +\sqrt{3}}\\\\\\\frac{5(\sqrt{11} +\sqrt{3})}{(\sqrt{11})^2 -(\sqrt{3})^2}\\\\\\\frac{5\sqrt{11} +5\sqrt{3}}{11 -3}\\\\\\\frac{5\sqrt{11} +5\sqrt{3}}{8}$
