Answer:
C= 25
B and D= 65
Step-by-step explanation:
The whole thing equals 180, and if one side (A) is 25 then the other side (C) is 25 too. 180-50= 130. 130/2 is 65 and that's B and D.
Answer:
140
Step-by-step explanation:
After Assuming a tax percentage of 3.5%, the tax amount gotten is $0.7
and the total cost of a double room, including tax is $20.7
<h3>Tax Calculation</h3>
Given Data
- Cost of double Room = $20
Amount of Tax paid = 3.5/100 * 20
= 0.035* 20
= $0.7
The total cost of a double room, including tax
= Cost of double + Amount of Tax
= 20+0.7
= $20.7

For all of them just use the Pythagorean theorem which is a squared plus b squared equals c squared where c is the hypotenuse (length of the side opposite the right angle) and a and b are legs. Just plug it in and solve for the missing length. For example, 1 would be (12) squared plus (5) squared equals c squared
Simplify to get 144 plus 25=c squared
169 equals c squared
Find the square root of both sides
c=13
Answer:
A.
Step-by-step explanation:
Both equations are solved for y so I'm just going to substitute
the 1st y (the 2x+4) into the second equation's y.
I'm going to get everything on one side so I have 0=ax^2+bx+c.
Subtract 2x and subtract 4 on both sides:
Since the coefficient of x^2 is 1, all we have to do is find two numbers that multiply to be -6 and add up to be -1.
These numbers are -3 and 2.
So the factored form of our equation is:
This means we have x-3=0 or x+2=0.
x-3=0
Add 3 on both sides:
x=3
x+2=0
Subtract 2 on both sides:
x=-2
So now we need to find y. I'm going to choose to use the easier equation:
y=2x+4.
If x=3, then y=2(3)+4=6+4=10. The ordered pair (3,10) is a solution.
If x=-2, then y=2(-2)+4=-4+4=0. The orded pair (-2,0) is a solution.
