21+1.7+0.25=22.95
You add 21+1.7, which equals 22.7, then add 0.25 to get 22.95.
Answer:
angle A is 63 degrees,
angle B is 57 degrees
Step-by-step explanation:
first, let's create the equation. Pretty simple, because angles a and b become 120 degrees when added up, this this will become:
2x+3+2x-3=120
now, we make it simpler. In this case, just add up the numbers that we can add up. this eventually becomes:
4x=120
now, all we need to do is divide 120 by 4, which becomes 30. So, x=30.
substitute the 30 into the x in the original equation, and this becomes:
60+3+60-3=120
63+57=120
thus, angle A is 63 degrees, and angle b is 57 degrees.
Let
x=12 in------------- > the longest of the three sides
y=6 in
z= 9 in
if x< (y+z)----------- > one unique triangle <span>can be made
if x> (y+z)----------- > </span><span>no triangle can be made
</span>This is a Triangle Inequality Theorem
therefore
x=12
(y+z)=15
12<15------------ >one unique triangle can be made
the answer is the option <span>B. 1</span>
Answer:
No, It is not equal to a 60% discount.
Step-by-step explanation:
Think of this. I go into a store and everything is 50% off and I have a coupon myself that is a 50% off discount for a specific item. It may seem like the item is now free, but it isn't. Imagine the item was $1 before any discount. Then the store took 50% off of the $1, leaving it at $0.50. So now with my discount of 50% off the item I will be taking this 50% off of $0.50 = my final discounted cost of $0.25.
Hope I helped you understand :)
