Answer:
Option A= 250
Step-by-step explanation:
Coterminal angles are angles in standard positions having thesame terminal .
Coterminal angles are always negative and positive.
For example:
The coterminal angle of 30° is-
30 - 360 = -330
30 + 360 = 390
Therefore, -330 and 390 are coterminal.
So, to the question:
The angles between 0 -360 coterminal to -110 is 250.
Prove:
250 - 360 = -110
250 + 360 = 610
Option A is correct
To solve this problem, we must first find the discount amount, and then subtract this amount from the total price of the item.
To find the discount amount, we must find 35% of $40. To do this, we must first convert 35% to its decimal equivalent by dividing 35/100. We do this because percentages are parts out of a total 100 percent, thus this fraction represents an equivalent value that we can multiply by other numbers. Using our knowledge that 35/100 = 0.35, we can now set up our expression:
35% of $40 (keep in mind that the word "of" refers to multiplication in math)
0.35 * 40
To solve, we just multiply these two numbers together, which gives us 14.
This means that Kala got a discount of $14 off of the original price of $40. To find out how much she paid for it, we must subtract $14 from $40, as modeled below:
$40 - $14 = $26
Therefore, Kala paid $26 for the item.
Hope this helps!
X+y=2(x-y)
x+y=2x-2y
3y=x
x-2y=2
then,substitute
(3y)-2y=2
y=2
so,x=3(2)
x=6
x the largest
y the smallest
Answer:
A=9in,b =9in
Step-by-step explanation:
This is a right angled triangle
Formula = a2×b2=c2 (ie sq of both adj sides equals the sq of the longest side)
So, a2 × b2 = c2
But both sides are equal, so we can as well say 2(a2) = (9|2)^2
2a^2 = 162
Divide through by 2
A^2 = 81
So, a = |81
A = 9
And since both sides are equal, a = b = 9
Answer:
It isn't?
Step-by-step explanation:
Step 1:
x + 8y = 21
x + 8y - 8y = 21 - 8y
x = -8y + 21
Step 2:
(-8y + 21) + 8y = 21
-8y + 21 + 8y = 21
21 = 21
