Add the 3 ratio portions together: 1 + 4 + 7 = 12

Divide total length by 12:

84/12 = 7

Multiply each ratio portion by 7:

1 x 7 = 7

4 x 7 = 28

7 x 7 = 49

The longest piece is 49 cm

A koala weighs 20 pounds. In her pouch she carries her joy that weighs 20 ounces. What is the combined weigth of the adult koala
sdas [7]

Answer: The answer is 21.25 pounds.


Step-by-step explanation:  Given that the weight of Akoala is 20 pounds. Also, she is carrying her joey with her having weight 20 ounces. We need to find the combined weight of the adult Akoala and her joey in ounces.

For that, first we need to conver ounces to pounds.

We know

1~\textup{pound}=16~\textup{ounces}\\\\\Rightarrow 1~\textup{ounce}=\dfrac{1}{16}~\textup{pounds}\\\\\Rightarrow 20~\textup{ounces}=\dfrac{1}{16}\times 20=\dfrac{5}{4}=1.25~\textup{pounds.}

Therefore, the combined weight is given by

W=20+1.25=21.25~\textup{pounds.}

Thus, the answer is 21.25 pounds.

In the diagram, AB = 10 and AC = . What is the perimeter of △ABC?
Mamont248 [21]

<u>Answer</u>

20 + units


<u>Explanation</u>

Perimeter is the distance all round a figure.

AB = 10. This is given in the question

AC = √((3-5)²+(4--2)²

= √(4+36)

=√40 = 6.32 units

BC = 5 - -5 = 10 units


Perimeter = AB+AC+BC

= 10+6.32+10

= 26.32 units

From the choices, we do not have an exact answer. The one that mosts suits the perimeter is 20 + units.
