The price of a dress was reduced from $40 to $30. By what percentage was the price of the dress reduced? STEP BY STEP
VARVARA [1.3K]

Answer:

The price was reduced by 25%

Step-by-step explanation:

Not sure how to go step by step on this, because it's kinda obvious once you think about it a bit. You need to find what percent of 40 that 10 equals (if that  makes sense). So really it's just what percent of 40 equals 10? and since 10 is one fourth of forty, 1/4, then you convert that to percent: 25% (sorry if this made no sense, i'm not very good at explaining things)

What is the value of z?
crimeas [40]

Answer:

23°

Step-by-step explanation:

The total of the angles in a triangle add up to 180°.

Our equation here is 62 + 95 + z = 180

Lets find what 62 + 95 is: 62 + 95 = 157

Then we can find the remainder (157 + x = 180). 180 - 157 = 23°

Therefore the missing angle (z) is 23°

What is the value of y?
Amiraneli [1.4K]

Answer:

\boxed{D. \: 40\degree}

Step-by-step explanation:

<em>Angle sum property of triangle states that the sum of interior angles of a triangle is 180°</em>

So,

=  > 2y \degree + (y + 10)\degree + 50\degree = 180\degree \\  \\  =  > 2y\degree + y\degree + 10\degree + 50\degree = 180\degree \\  \\  =  > 3y\degree + 60\degree = 180\degree \\  \\  =  > 3y\degree = 180\degree - 60\degree \\  \\  =  > 3y\degree = 120\degree \\  \\  =  > y =  \frac{120\degree}{3\degree}  \\  \\  =  > y = 40\degree
