AB = 3 + x

strojnjashka [21]

Answer:

Option A) 4, 2

Step-by-step explanation:

We are given that quadrilateral ABCD is a parallelogram with sides:

$AB = 3 + x\\DC = 4x\\AD = y + 1\\BC = 2y$

Since the opposite sides of a parallelogram are equal, we can write:

$AB = DC\\AD=BC$

Equating the sides we get,

$\Rightarrow 3+x = 4x\\4x-x = 3\\3x = 3\\x = 1\\\Rightarrow y + 1 = 2y\\y = 1$

Putting the values of x and y, we get:

$AB = 3 + x =4\\DC = 4x =4\\AD = y + 1=2\\BC = 2y=2$

Thus, the lengths of the opposite side pairs is 4,2.

If the ratio of the triangular pyramids' surface areas is 4:9, what is F?

VladimirAG [237]

Answer:

The answer to your question is f = 10.35 in

Step-by-step explanation:

Data

Proportion = 4:9

height 1 = 4.6 in

height 2 = f

Process

1.- Write the proportion

$\frac{4}{4.5} = \frac{9}{f}$

2.- Solve for f

$f(\frac{4}{4.6}) = f(\frac{9}{f})$

$f(\frac{4}{4.6}) = 9$

$4.6\frac{4f}{4.6} = 9(4.6)$

4f = 41.4

$\frac{4f}{4} = \frac{41.4}{4}$

f = 10.35 in
