Answer:
y = -2
Step-by-step explanation:
First, we subtract 2y on both sides:
-24 = 12y
Then, we divide 12 on both sides:
y = -2
And we're done ^^ hope this helps!
Start out by finding the area of the square.
a = 4²
a = 16
Since all we have to look at is 1/4 of this square, multiply the area by 1/4.
(16)1/4
4
The area of the triangle is 4.
Now we need the area of the circle.
a = πr²
Sub: a = π(2)²
a = π(4)
Since the portion of the circle that covers the triangle is 1/4 of the circle, subtract 1/4 of the area of the circle from the area of the circle.
a = 4 - 1/4(π(4))
a = 4 - 1/4π x 1
a = 4 - 1/4π
Now this is where it's supposed to go, considering the fact that π isn't given a value.
Normally, I'd use 3.14 for π, as the entire population would, and then it would be easy, but obviously that isn't an option.
Now this answer isn't up there, so my best option is to tell you it's most likely c, and I hope I'm right.
Uhh good luck I guess this math test is weird

Answer:
27.4 km
Step-by-step explanation:
vertical line- y
17 km/y= tan 54
y= 17/tan 54= 25.2 km
25.2/x= cos 23
x= 25.2/cos 23= 27.4 km
Answer:
The regular price=$750
Step-by-step explanation:
Step 1
Let the regular price be x
regular price=x
Step 2
The expression for the price after the discount is;
price after discount=regular price-discount rate×regular price
where;
regular price=x
discount rate=25%
replacing;
price after discount=x-(25/100)×x=x-0.25 x=0.75 x
price after discount=0.75 x
Step 3
Get the expression for the final bill as shown;
final bill=price after discount-gift certificate
where;
final bill=$522.50
price after discount=0.75 x
gift certificate=$40
replacing;
522.50=0.75 x-40
0.75 x=522.50+40
0.75 x=562.50
x=562.5/0.75
x=750
The regular price=$750
