Answer:

30

Step-by-step explanation:

12/? = 40/100

Butterfly method and we get 30

Also if 12 cats are 40 percent then that means that 24 cats would be 80 percent. And 6 cats would 20 percent. So 12 plus 12 plus six equals 30.

Find the volume and show work to be brainliest
stiks02 [169]

Answer:

(7) 1482 in³

(8) 216 yd³

Step-by-step explanation:

Formulas

<u>Volume</u><u> </u><u>of</u><u> </u><u>prism</u>

= base × height/length

<u>Area of parallelogram</u>

= base × height

<u>Area of trapezium</u>

= (upper base + lower base) × height ÷ 2

(7)

Area of the base = 19×6

= 114 in²

Length = 13 in

Volume = 144×13

= <u>1482 </u><u>in</u><u>³</u>

(8)

Area of the base = (11+7)×12÷2

= 108 yd²

Length = 2 yd

Volume = 108×2

= <u>216 yd³</u>

Rose is fishing from a small boat. A fish swimming at the same depth as the hook at the end of her fishing line is 8 meters away
tensa zangetsu [6.8K]

The question is incomplete, as the depth of the hook isn't given in the question. However, using a proposed depth for the hook, we could give a stepwise solution to the exercise.

Answer:

Kindly check explanation

Step-by-step explanation:

If given a hook depth of 6 meters, and a distance of 8 m(fishing line from hook) at the the Same depth, then the distance between rose and the fish, x can be calculated, using the relation.

Hypotenus² = opposite² + adjacent²

(refer to attached picture)

x² = 6² + 8²

x² = 36 +. 64

x² = 100

x = sqrt(100)

x = 10 meters

You can use the actual depth value to obtain the actual solution to your question.
