Answer:
Well this is kinda confusing
Step-by-step explanation:
im explaining the best way I can.
for exp 10 to the power of four = 40
but 10 to the power of 0 is 10
This is because your not multiplying by anything. it's just a normal number. I'm sorry I don't know what I got at here but I hope it helps a little. I'm honestly really sorry.
B:
Explanation that equation is the B
Answer:
C. $30
Step-by-step explanation:
Given
Cost = $240
down payment = $60
remainder = $240 - $60 = $180
given that the remainder is to be split into 6 equal paments
each payment = $180 ÷ 6 = $30
248,700
682 is closer to 700 than to 600
Let 'x' denote the length of the base and let 'y' denote the length of the legs.
We know that isosceles triangles have one base and two legs that are the same length. So, the perimeter is:
x+y+y
= x+2y = 50
The problem tells us that the base is half as long as a leg, so that means:
y=2x
We can use the method of substitution here. Let's substitute the 2nd given equation into the first one. The work follows:
x+2y=50
x+2(2x)=50
x+4x=50
5x=50
x=50/5
x=10
To work out what the length of our legs are, we can use our found 'x' value to solve either of our previously established equations. Let's use the second one:
y=2x
y=2(10)
y=20
Just to confirm our answer is correct, let's verify it with our first equation.
x+y+y=50
10+20+20=50
50=50
Our answer is consistent, so the base has length 10, and each leg has length 20.
