Dr. Piegan treated 440 dogs. The percentage of obese dogs increased from 52.5 percent in 2010 to 55.0 percent in 2011. What was the percent increase?

Answers

Well, the formula for finding percent change is (amount of change)/(original amount) . So, the amount of change is 2.5 and original amount is 52.5. Then, to get the percent increase, you divide 2.5 by 52.5 which is 0.047619048. You multiply by 100 since its percent and get 4.7619048. But you should probably round to the nearest tenth ≈ 4.8%.

BRAINLIEST!!!!The table shows the high temperatures (in degrees Fahrenheit) of four different cities on a specific day. Which cities reach a warmer temperature than Snowville?

City Temperature (°F)
Breezetown −3.2
Arcticville −11/2
Iceburgh −9/4
Snowville −3 1/2

Breezetown

Arcticville

Iceburgh

Answers

Breezetown and Icebrugh because Snowville is -3 1/2 which turns to -3.5 and if you divide 9 by 4 you will get -2.25 which is higher than -3.5. -3.2 is also higher than -3.5. Arcticville is not one becuase if you divide 11 and 2 you end up with -5.5.

It is Iceburg

Because of the unexpected cold weather,the cost of tomatoes increased 50 percent in one month.If the cost after the increase was 60 cent per pond,what was the cost before the increase?

Answers

A 50% increase is just taking the original amount and adding half of that towards the amount.

Example : 50% of 100 is 50 so a 50% increase to 100 would be 150

a formula for this would be X + (1/2×X) = Y

in your case we're working backwards with the known being 60

We can just plug in reasonable values for X until we get 60

50% of 40 is 20

40 + 20 = 60

so the original amount was 40

A girl is 6 years older than her brother than her brother. In 3 years she will be 2 years older than twice what his age will be then. What are their ages now?

Answers

Answer:

1 = brother's age now.

4 = brothers age in 3 years.

7 = girls age now.

10 = girls age in 3 years.

Step-by-step explanation:

You want to get x by itself first.

(x + 6) + 3 = 2(x + 3) + 2

x +9 = 2x + 8

-x + 9 = 8

-x = -1

x = 1

This is her brothers age when she is 6 years older than him.

Now you will take the 1 and put it in the x +3 = brother's age in 3 years.

The brother will be 4 in 3 years.

The girl will be 7 when her brother is born.

Then you will take the 1 and put it into (x + 6) +3 = 10.

The girl will be 10 in 3 years.

1 = brother's age now.

4 = brothers age in 3 years.

7 = girls age now.

10 = girls age in 3 years.
