Please help find the percent of decrease?!

Greeley [361]

decrease = 9%

percent decrease = $\frac{decrease}{original cost}$ × 100%

decrease = $98 - $89 = $9

percent decrease = $\frac{9}{98}$ × 100% = 9% (to nearest whole percent )

What is the slope of a line perpendicular to a line with slope –9?

7nadin3 [17]

Answer:

The answer is 1/9.

Step-by-step explanation:

When solving for the slope of a perpendicular line to a given, you have to flip the opposite reciprocal.

First take the number and flip the reciprocal, in this case -9 turns into -1/9.

Then flip the sign, like making a negative to a positive or a positive to a negative. In this case make -1/9 into 1/9

Therefore the answer is 1/9.

X - 35 > 15 i need answer IMEDIATLEY

SIZIF [17.4K]

I'm assuming you want us to solve this inequality for x, since the question wasn't too clear on that.

$x - 35 > 15$

Add 35 to both sides to remove the "-35" on the left side so we can isolate the x

$x-35+35>15+35$

$x>50$

The solution to this inequality is x>50. Let me know if you need any clarifications, thanks!

Quadrilateral ABCD has congruent angles and opposite sides that are congruent. What classification can be given to ABCD? (5 poin

fgiga [73]

All angles are congruent.
The sum of the measures of the interior angles of a quadrilateral is 360.
Since all angles are congruent, then each angle must measure 360/4 = 90.
Every angle measures 90 degrees.
The quadrilateral must be a rectangle.
Is the quadrilateral also a square?
We are told "opposite sides that are congruent." Since only opposites sides are congruent, and not all sides are congruent, then it is a rectangle, but not necessarily a square.

Answer: B. rectangle
