How to change a precent to a decimals

To change a percent to a decimal, you must move the decimal point inwards two places. For example, say you have 45%. To change 45% to a decimal, move the decimal point in two places, and you will have 0.45. Once you’ve moved the decimal, don’t add the percent symbol, because it’s no longer a percent.

Grab your percentage like 100% then move the invisible decimal two places to the right 1.00 making it 1

In the figure, mZRPZ = 95 and TU ||RQ|| VW. Find the measure of angle YSV.

madreJ [45]

Answer:

$m\angle YSV=85^o$

Step-by-step explanation:

The complete question in the attached figure

step 1

Find the measure of angle QPZ

we kno that

$m\angle RPZ+m\angle QPZ=180^o$ ---> by supplementary angles (form a linear pair)

we have

$m\angle RPZ=95^o$ ---> given value

substitute

$95^o+m\angle QPZ=180^o$

$m\angle QPZ=180^o-95^o$

$m\angle QPZ=85^o$

step 2

Find the measure of angle YSV

we know that

When two lines are crossed by another line, <em><u>Alternate Exterior Angles</u></em> are a pair of angles on the outer side of each of those two lines but on opposite sides of the transversal. If the two lines are parallel then the alternate exterior angles are congruent.

In this problem

The transversal is the line XY

The two parallel lines are RQ and VW

therefore

$m\angle YSV=m\angle QPZ$ ---> by alternate exterior angle

we have

$m\angle QPZ=85^o$

therefore

$m\angle YSV=85^o$

Which of the following equations has a slope of -2 and passes through the point (3,-4)?

Mashutka [201]

Answer:

B

Step-by-step explanation:

y=-2x+2

y=mx+b

m is slope so.here m is -2

y=-2+10.passes through the point (3,-4)

because -4=-2*3+2

-4=-6+2

-4=-4
