Tammy brought 3 apps for $2.40. At the same price, how much would 10 apps cost

vitfil [10]

Answer:

The answer is $8.00.

Step-by-step explanation:

First, you have to find how much for each app so you have to divide by 3 :

3 apps = $2.40

1 app = $2.40 ÷ 3

1 app = $0.80

Next, you have to multiply it by 10 :

1 app = $0.80

10 apps = $0.80 × 10

10 apps = $8.00

The circular area covered by a cell phone tower can be represented by the expression 225π miles2. What is the approximate length

Irina18 [472]

Answer:

The length of the diameter of this circular area is of 30 miles.

Step-by-step explanation:

The area of a circular region can be represented by the following equation:

$A = \pi r^{2}$

In which r is the radius. The diameter is twice the radius.

In this question:

$A = 225\pi$

$A = \pi r^{2}$

$225\pi = \pi r^{2}$

$r^{2} = 225$

$r = \pm \sqrt{225}$

The radius is a positive measure, so

$r = 15$

Area in squared miles, so the radius in miles.

What is the approximate length of the diameter of this circular area

D = 2r = 2*15 = 30 miles

The length of the diameter of this circular area is of 30 miles.

One-quarter of the sum of 2 consecutive odd numbers is 14. Find the numbers.

aalyn [17]

Answer:

27 and 29

Step-by-step explanation:

let A and B the expected numbers

assuming B = A + 2, the problem can be written as follows

¼(A + A + 2) = 14

4*¼(A + A + 2) = 4*14

(A + A + 2) = 56

2A + 2 = 56

A + 1 = 28

A = 27

B = 27 + 2 = 29
