Answer:
The answer is 7 cups
Step-by-step explanation:
1 cake-2 2/6 cups
Which can also be written as
1 cake-14/6 cups
3 cakes-x cup
Cross multiply
x=14/2
x=7
Therefore Karen needs 7 cups of flour to make 3 cakes
Answer:
301.42 ft from base
Step-by-step explanation:
We can look at this situation as a triangle, the cliff is straight up and we're looking for the lowest side of the triangle. So to figure this out we use tangent, tangent is equal to Opposite over adjacent. So the tangent(37)= bear from base/height of cliff. We then multiply tan(37) by 400 to get the answer
Answer:
Step-by-step explanation:
Base + 4 triangles
(18.4)(27.6) + 2(½×27.7×17.6) + 2(½×18.4×20.4)
Answer:
The length of the rectangle is 6cm while the width is 9cm
Step-by-step explanation:
Here, we are interested in calculating the length and width of the rectangle.
Let the length of the rectangle be x cm
We are told that the length is 3 cm
less than the width, this means that the width is (x + 3) cm
The area of the rectangle is 54cm^2
Mathematically;
Area of rectangle = L * B
Thus;
x(x + 3) = 54
x^2 + 3x = 54
x^2 + 3x -54 = 0
x^2 + 9x -6x -54 = 0
x(x + 9 ) -6(x + 9) = 0
(x -6)(x + 9) = 0
x -6 = 0 or x+ 9 = 0
x = 6 or -9
Since length cannot be negative we choose x = 6cm
But width = x + 3 = 6 + 3 = 9cm
