Yes.<span>a multiple of 3=add the numbers so 8 plus 1 is 9 and divide that by 3 it works
2.no.</span>fthe number formed by its last two digits is divisible by 4, the original number is as well.
3.no.take the last digit, double it, and subtract it from the rest of the number.
4.yes.<span>Add the digits. If that sum is divisible by nine, then the original number is as well.</span>
<span>5.no . has to work with both
</span><span>Multiple of 2 --> is even (ends with 0, 2, 4, 6 or 8) </span>
<span>Multiple of 3 --> digits add up to a multiple of 3. </span>
Answer:
x=80* y=20* and X=100*
Step-by-step explanation:
If we assume PQ || OR then by alternate interior angles x is equal to 80 degrees and y is equal to 20 degrees.
We know that a triangle adds up to 180 degrees.
Angle ROX and XRO add up to 100 degrees. Leaving RXO equal to 80 degrees. (180-100=80).
By opposite angles, QXP is equal to 80 degrees also.
Then we are left with solving for X.
Supplementary angles add up to 180 degrees.
Subtract angle OXR from 180 and we are left with angle OXP = X = 100 degrees.
Answer:
12 ft
Step-by-step explanation:
You have a right triangle with the hypotenuse = 13 and one leg = 5
Let x = distance above the ground that the ladder touches the wall
Now use the Pythagorean theorem
![x^{2} + 5^{2} = 13^{2} \\x^{2} + 25 = 169\\x^{2} = 144\\x = \sqrt{144} = 12](https://tex.z-dn.net/?f=x%5E%7B2%7D%20%20%2B%205%5E%7B2%7D%20%3D%2013%5E%7B2%7D%20%5C%5Cx%5E%7B2%7D%20%20%2B%2025%20%3D%20169%5C%5Cx%5E%7B2%7D%20%20%3D%20144%5C%5Cx%20%3D%20%5Csqrt%7B144%7D%20%3D%2012)
It looks like none of the choices are correct, because the answer is 12 ft.
By the way, it is impossible for the ladder to reach up the wall a distance longer the the length of the ladder. Think about it. OK?
Answer:
Undefined or Infinity
Step-by-step explanation:
(x1,y1)=(-11,8)
(x2,y2)=(-11,-17)
Slope = (y2-y1)/(x2-x1)
= (-17-8)/(-11-(-11))
= -25/0
= Undefined
