Answer:
£12
Step-by-step explanation:
9.60 = 80% times y.
9.60 = 0.8y
Then, divide each side by 0.8 to get the equation in shape to solve for y.
y = 9.60/0.8
y=12
1,348 is 1000 and 2,332 is 2,300
<span>f(x) = 2x – 4
</span><span>inverse
x = 2y - 4
2y = x + 4
y = x/2 + 2
answer
inverse
f-1(x) = </span>x/2 + 2
Answer:
-1
Step-by-step explanation:
f of 3 is the same thing of f of x which is y. The questions is saying if x is equal to 3, then what is y. x is represented by domain and y is represented by range. If you find x which is 3 in the domain, then the arrow points to negative 1 in the range circle.
Answer:
56 cm^2
Step-by-step explanation:
Surface area is just finding the areas of each face in a figure. As we are given a net of a figure, it is much easier for us to calculate it.
Area of square base (side^2)
4^2 = 16 cm^2
Area of ONE triangular face (1/2 x b x h):
1/2 x 4 x 5 = 10 cm^2
Multiply that by 4 because we have 4 triangular faces: 10 cm^2 x 4 = 40 cm^2
ADD all the areas of triangles and square:
16 cm^2 + 40 cm^2 = 56 cm^2
HOPE THIS HELPS
Have a nice day!
