14/15

5/15 + (3x3 / 3x5) = 5/15 + 9/15 = 14/25

Answer 14/15

Step-by-step explanation:You want to get a common denominator for both fractions so you multiply 3/5 by 3 to get 9/15. Now you add 5/15 and 9/15 to get the answer. 5+9=14. And since the denominators are the same you leave them alone.

If your starting salary were $40,000 and you received a 3% increase at the end of every year for 15 years, what will be the amou

Valentin [98]

Answer:

<u>The salary during the 16th year will be US$ 62,318.70</u>

Step-by-step explanation:

Starting salary = US$ 40,000

Duration of the job contract = 15 years

Salary increase rate = 3% compounded annually

2. Let's find the future value of this starting salary after 15 years, using the following formula:

FV = PV * (1 + r) ⁿ

PV = Starting salary = US$ 40,000

number of periods (n) = 15 (15 years compounded annually)

Salary increase rate (r) = 3% = 0.03

Replacing with the real values, we have:

FV = 40,000 * (1 + 0.03) ¹⁵

FV = 40,000 * (1.03) ¹⁵

FV = 40,000 * 1.558

FV = US$ 62,318.70

<u>The salary during the 16th year will be US$ 62,318.70</u>

What is the simplified base of the function f(x) = One-fourth (Root Index 3 StartRoot 108 EndRoot) Superscript x?

son4ous [18]

Answer:

Simplified base would be 3∛4

Step-by-step explanation:

Given exponential function,

$f(x)=\frac{1}{4}(\sqrt[3]{108})^x$

Since, in an exponential function $f(x)=ab^x$

b is called base.

∵ 108 = 2 × 2 × 3 × 3 × 3,

Or 108 = 4 × 3³,

$\implies \sqrt[3]{108} = \sqrt[3]{4\times 3^3}$

$\sqrt[3]{108}=\sqrt[3]{4}\times \sqrt[3](3^3)$ ( Using $\sqrt[n]{ab}=\sqrt[n]{a}\times \sqrt[n]{b}$ )

$\sqrt[3]{108}=\sqrt[3]{4}\times (3^3)^\frac{1}{3}$

$\sqrt[3]{108}=\sqrt[3]{4}\times 3^{3\times \frac{1}{3}}$ ( Using power of power property of exponent )

$\sqrt[3]{108}=3\sqrt[3]{4}$

Hence, the required simplified base would be 3∛4

i.e. SECOND option is correct.

Summer school math problem

Ronch [10]

Hello!

4/18 = 6/27 ?

4 × 27 = 18 × 6

108 = 18 × 6

108 = 108 => 4/18 = 6/27

4/6 = 16/36 ?

4 × 36 = 6 × 16

144 = 6 × 16

144 ≠ 96 => 4/6 ≠ 16/36

3/4 = 9/12 ?

3 × 12 = 4 × 9

36 = 4 × 9

36 = 36 => 3/4 = 9/12

5/9 = 8/12 ?

5 × 12 = 9 × 8

60 = 9 × 8

60 ≠ 72 => 5/9 ≠ 8/12

Good luck! :)
