Answer:
<em>1,860</em>
Step-by-step explanation:
FIRST:
we divide 124 by 4 because in 4 minutes he can type 124 words, and we need to figure out how many he can type in a minute.
124 divided by 4 is 31. (they can type 31 wpm)
NEXT: now we know they can type 31 wpm, we need to multiply that number by 60 because there are 60 minutes in an hour.
31 x 60 = 1,860
therefore, they can type 1860 words per hour
hope i helped have a great day/night! :'')
Answer:
49.4 degrees
Step-by-step explanation:
In Triangle AXY,
We want to determine the angle of elevation from the point Vera is standing to the top of the flagpole, which is the angle at V in the diagram.
In Triangle XVY
|VY|=36 feet
Therefore, the angle of elevation from the point Vera is standing to the top of the flagpole is 49.4 degree to the nearest tenth of a degree.
The 1905 was 3.0 inches while 2004 was 4.2 inches since they are 1.2 apart and they add up to 7.2
X=-8,3.
divide all terms by the two in the first term to get x^2+5x-24=0. Then find the factors. To do so, find what two numbers can be multiplied to get 24, and whether those two numbers can be added or subtracted to get the middle term (5). Since 8x(-3)=24 and 8-3=5, (x+8) and (x-3) are the factors. Then set the factors equal to zero. Add or subtract these numbers to the other side of the equation and you then get x=-8,3. These are the roots.
