Haley got a 93% on her first math test and an 86% on her second test. What is her percent decrease from test 1 to test 2 to the
zhenek [66]

Haley’s Percentage Decrease from Test 1 to Test 2 to the nearest tenth is 7.5%

Nearest tenth can be defined as , Look at the hundredth number to round the decimal number to the nearest tenth. If it's more than 5, add one to the tenth value. Remove all the numbers that are present after the tenth place and leave the tenth place value alone if it is less than 5

Given that,

Haley’s Percent score in Test 1 = 93 %

Haley’s Percent score in Test 2 = 86%

Formula For calculating the Percentage Decrease is :

(Beginning Percentage – Final Percentage) / Beginning Percentage * 100

So, by using this formula we can calculate the percentage decrease of Haley’s Test

Percentage Decrease = (93% - 86%)/93% * 100

                 = 7.5%

Y/x^2 + y/x^3<br><br>perform the operation and express your answer as a single fraction​
umka2103 [35]

Answer:

\frac{y}{x^2}+\frac{y}{x^3}=\frac{yx+y}{x^3}

Step-by-step explanation:

Given the expression

\frac{y}{x^2}+\frac{y}{x^3}

Let us perform the operation and express your answer as a single fraction​

\frac{y}{x^2}+\frac{y}{x^3}=\frac{x^3y+x^2y}{x^5}

            =\:\frac{x^2\left(xy+y\right)}{x^5}

            =\frac{\left(xy+y\right)}{x^3}

Therefore, we conclude that:

\frac{y}{x^2}+\frac{y}{x^3}=\frac{yx+y}{x^3}
