A brand of cereal had 1.2 milligrams of iron per serving. Then they changed their recipe so they had 1.8 mg of iron per serving.
Anvisha [2.4K]

Using it's concept, it is found that the percent increase in the amount of iron per serving was of 50%.

<h3>What is the percentage increase of a value?</h3>

It is given by the increase divided by the initial value, and subtracted by 100%.

In this problem:

  • The initial value is of 1.2 mg.
  • The increase was of 1.8 mg - 1.2 mg = 0.6 mg.

Hence the percent increase is given by:

P = 0.6/1.2 x 100% = 50%.

Identify the correct explanation and the similarity statement for the similar triangles.
Tatiana [17]

Answer:

Option B

Step-by-step explanation:

From the picture attached,

In ΔABC,

m∠B = m∠C = 75° [Isosceles triangles]

By applying triangle sum theorem,

m∠A + m∠B + mC = 180°

m∠A + 75° + 75° = 180°

m∠A = 180° - 150°

m∠A = 30°

In triangle PQR,

m∠P = m∠Q [Isosceles triangle]

By applying triangle sum theorem,

m∠P + m∠Q + m∠R = 180°

2(m∠P) + 30° = 180°

m∠P = 75°

m∠P = m∠Q = 75°

In ΔABC and ΔRPQ,

m∠B ≅ m∠Q [Given]

m∠C ≅ m∠R [Given]

Therefore, by AA property of similarity of two triangles, both the triangles will be similar.

ΔABC ~ ΔRPQ

Option B will be the answer.

The ratio of koalas to gum trees is 1 : 3. There are 252 gums trees now. Plans are being made to increase this number to 345. Fi
Advocard [28]
I would be happy to help!

To start off you need to find the amount of koalas there are at the current number of trees by using the ratio one to 3 which means there is one koala for every 3 gum trees. So you need to devide 252 by 3 giving you the answer of 84 koalas currently. Now you nees to find how many koalas there are for the future 345 trees based on the same ratio 1 to 3. This would give you 115 koalas to be expected in the future. Finally to find the amount of koalas increaed you need to subtract 84 from 115 giving you a final answer of 31 koalas.
