Step-by-step explanation

(9).

ΔXYZ ≅ ΔRST

XZ = RS

XZ = 60

RS = 60

(10).

ΔABC ≅ ΔEDC

AC = EC

EC = 56

AC = 56

(11).

ΔJKL ≅ ΔMKN

JL = MN

3x - 2 = x + 1

2x = 3

x = 3/2 ⇒ x = 1.5

(12).

ΔBCD ≅ GEF

BD = GF

BD = 57

(13).

ΔPQR ≅ SQT

PQ = SQ

x + 5 = 8

x = 8 - 5

x = 3

(14).

ΔCDE ≅ GDF

ED = FD

ED = 4

A greedy hamster hoarded 2 piles of sunflower seeds. Yesterday the ratio of the seeds in these piles 3:4; but today the greedy h
poizon [28]

The weight of each pie will be 6 and 8 pounds respectively if the ratio of the seeds in these piles 3:4

<h3>What is the ratio?</h3>

It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.

We have:

A greedy hamster hoarded 2 piles of sunflower seeds. Yesterday the ratio of the seeds in these piles was 3:4

Let 3x and 4x are the seeds from the smaller and bigger pile.

= 4x + 2  (greedy hamster placed another 2 pounds of seeds in the bigger pile)

= 3x - 1/4 (ate 1/4 pound from the smaller pile)

4x + 2 = 5x

Because the quantities of seeds in those piles is in the ratio of 5:16

After solving:

x = 2

Smaller pile weight = 3x = 3(2) = 6

Bigger pile wieght = 4x = 4(2) = 8

Thus, the weight of each pie will be 6 and 8 pounds respectively if the ratio of the seeds in these piles 3:4
