Mathematics

Answer:

Approx. 59% increase.

Step-by-step explanation:

Today - 221

Yesterday - 139

difference (today - yesterday) = 82

How to find percent:

((part)/(whole)) = ((x)/(100))

In this case, the part is the difference, and the whole is the value of an item yesterday, so the equation is:

82/139 = x/100

cross multiply

8200 = 139x

Inverse operations

8200 = 139x

/139       /139

8200/139 = x

approx. 59 = x

What is the area of the shaded sector? (Round to the nearest tenth)<br> 10<br> 38
masya89 [10]

Answer:

33.1

Step-by-step explanation:

First you need to find the area of the circle. The radius is 10 which means that the area is 314. Since a circle has 360 degrees, and the shaded area is 38 degrees, you need to divide 314 by 360 which is 0.87. Then multiply by 38 because the shaded sector is 38. 0.87 x 38 = 33.1.

That is the answer.

7nadin3 [17]

Answer:

Katie needs to pay $27.9.

Step-by-step explanation:

Given;

Cost of per foot = $2.25

Number of  flowers in her yard = 12.4 square foot

We need to find how much she needs to pay.

Solution:

Now we know that;

1\ ft^2 = \$2.25

So for 12.4 ft^2 = Cost for 12.4 ft^2 .

By using Unitary method we get;

Cost for 12.4 ft^2 = 2.25\times12.4= \$27.9

Hence Katie needs to pay $27.9.
