Answer:

40%

Step-by-step explanation:

a percentage can also be written as something over 100. x/100. to find the percentage you would set up the proportions as 12/30=x/100. then you cross multiply 12x100 and divide by 30. (this is called the bat and ball method). you end up with 40.

kolbaska11 [484]

Answer:

1:6 or 1/6

Step-by-step explanation:

Because the question asks for the goats to the total number of animals, you have to write the ratio in the same order. So, there are 4 goats, and to find the total number of animals, you just add every number.

5+11+4+4=24

The result would be 4:24, and because you need the ratio in the simplest form, you just divide both sides by the same greatest number. Both 4 and 24 can be divided evenly by 4. So, when you simplify, the answer comes out as 1:6. (Ratios can also be written as fractions, just so you know!! For example, the ratio 1:6 can be written as 1/6; both answers would be correct.)

Hope this helps!!!! Have an amazing day :3

If Hunter scored 1/5th of 50 points then:

Hunter = 1/5 × 50 = 10 points

Difference in points between Jenny and Hunter = 30 - 10 = 20 points

T=h+kg isolate g rearrange the formula above
Westkost [7]

Answer:

\frac{\left(t-h\right)}{k}\\ = g

Step-by-step explanation:

Subtract the h

t = h+kg

-h  -h

you get:

t-h=kg

now divide the k from both sides

\frac{\left(t-h\right)}{k}\\ = \frac{\left(kg\right)}{k}

so,

\frac{\left(t-h\right)}{k}\\=g
