gtnhenbr [62]

Answer:

Mrs.dean can type 150 words in a minute and a half. Mr.kovacs can type 96 words in 3/4 of a minute prove which teacher can type
slamgirl [31]
Mrs. Dean 150 words per minute, already set up nicely for us
Mr. Kovacs 96 words per 3/4 minute

So we need to adjust 96 words per 3/4 minute to what ever words PER MINUTE.

So, a simple way to do this is change 3/4 to decimal, which would be 0.75 in this case. Knowing that 96 words per 3/4 minute is 25% less than what he would type in a minute, we simply multiple 96 by 1.25 to make up for the 0.25 missing.

Which would get us: Mrs. Dean: 150 wpm
                                 Mr. Kovacs: 96(1.25)=120wpm

Therefore Mrs. Dean types at a greater rate of words per minute, 30 more words per minute to be exact.

What is the measure of the third angle in the similar triangles below?
WARRIOR [948]

Answer:

65

Step-by-step explanation:

We know that,

The Sum of all angles of the triangle is 180°.

As given in the question,

Triangle PQR is similar to Triangle WXY

Therefore ,

Let the third angle be 'x'.

35° + 80° + x = 180°

115 + x = 180°

x = 180° - 115°

x = 65°.

Hence, 65° is the appropriate answer to the question.

I hope my answer helped!!
