Misha's test score decreased from 80% to 60%. What was the approximate percent decrease of Misha's test score?

Elina [12.6K]

**IF YOU WANT TO KNOW WHAT THE DIFFERENCE IS BETWEEN 80% AND 60%
80% - 60 % is the same as 80 - 60.

80 - 60 = 20

So 20% is the answer.

She gave 1/3 of cookies for her husband 1/4 of the cookies to her son and 1/6 of a cookies to her neighbor she ate the remaining

beks73 [17]

She made 15 cookies

Solution:

Let "x" be the number of cookies she made

She gave 1/3 of cookies for her husband

Therefore,

$Husband = \frac{1}{3}x$

Find the remaining

$Remaining = x - \frac{x}{3} = \frac{3x-x}{3} = \frac{2x}{3}$

1/4 of the cookies to her son

Therefore,

$son = \frac{1}{4} \times \frac{2x}{3} = \frac{x}{6}$

Now again find the remaining

$Remaining = \frac{2x}{3} - \frac{x}{6} = \frac{x}{2}$

1/6 of a cookies to her neighbor

$Neighbor = \frac{1}{6} \times \frac{x}{2} = \frac{x}{12}$

Now again find the remaining

$Remaining = \frac{x}{2} - \frac{x}{12} = \frac{5x}{12}$

She ate the remaining six cookies

Therefore,

$\frac{5x}{12} = 6\\\\5x = 72\\\\x = 14.4$

Thus she made approximately 15 cookies

Identify the sequence as arithmetic, geometric, both, or neither. 50, –50, 50, –50, . . . both arithmetic geometric neither desc

stellarik [79]

Answer:

The sequence is geometric.

Step-by-step explanation:

In Arithmetic sequence, there is a common difference between any two consecutive terms but in Geometric sequence, there is a common ratio between any two consecutive terms.

Given sequence is: 50, -50, 50, -50,.................

Lets assume, the terms as $a_{1}, a_{2}, a_{3}, a_{4},...........$

Checking for common difference:

$a_{2}-a_{1}= (-50)-(50)= -100\\ \\ a_{3}-a_{2}=(50)-(-50)=100\\ \\ a_{4}-a_{3}=(-50)-(50)=-100$

As there is no common difference, so it's not an arithmetic sequence.

Checking for common ratio

$\frac{a_{2}}{a_{1}}=\frac{-50}{50}=-1\\ \\ \frac{a_{3}}{a_{2}}=\frac{50}{-50}=-1\\ \\ \frac{a_{4}}{a_{3}}=\frac{-50}{50}=-1$

As there is a common ratio, so it's a geometric sequence.

Find the coordinate of X if XY=1 and the coordinate of Y is 0.

rosijanka [135]

X is undefined.

XY = 1

Plug in 0 for Y. X(0) = 1

X = 1/0

So the answer is that X is undefined.
