Freida drove 50 miles in 15 minutes. At this rate, how many miles did she drive in 9

siniylev [52]

Answer:

30 miles

Step-by-step explanation:

The rate is distance /time

50 /15 =10/3 miles per hour

To find the distance traveled in 9 minutes, multiply the rate by the time

distance = 10/3 *9 = 30

30 miles

If a,b, and c are prime numbers, do (a+b)(a+b) and cc have a common factor that is greater than 1?

Answer:

1. Information is not sufficient

2. Information is not sufficient

Step-by-step explanation:

Question Modified

If a,b, and c are prime numbers, do (a+b) and c have a common factor that is greater than 1?

(1) a,b, and c are all different prime numbers

(2) c≠2

Explanation

1. Let's assume values of 1,3 and 5 to a, b, and c respectively

a + b = 1+3 = 4

4 and 5 do not have any common factor aside 1

Let's assume values of 1,3 and 2 to a,b and c respectively

a + b = 1+3 = 4

4 and 2 have a common factor of 2

So, the available information is not sufficient

Let's assume values of 2,7 and 3 to a b and c response

a + b = 2 + 7 = 9

9 and 3 have a common factor of 3

Also, let's assume values of 2,7 and 5 to a, b and c

a + b = 2 + 7 = 9

9 and 5 do not have a common factor

So, the available information is also not sufficient to answer the question.

Find the area: (I will give brainliest) +50 points.

scZoUnD [109]

Answer:

$A_{total} = 16\ cm^2$

Step-by-step explanation:

Step 1: Determine the area of the top rectangle

We can tell that the total shape seems like two rectangles glued together. We can separate the top rectangle and determine the area of it and then determine the area of the bottom rectangle and combine them. Lets first solve the left rectangle.

$A=l*w$

$A_{top\ rectangle}=6\ cm * 2\ cm$

$A_{top\ rectangle}=12\ cm^2$

Step 2: Determine the area of the bottom rectangle

$A=l*w$

$A_{bottom\ rectangle}=2\ cm * 2\ cm$

$A_{bottom\ rectangle}=4\ cm^2$

Step 3: Determine the total area

$A_{total}=A_{top\ rectangle}+A_{bottom\ rectangle}$

$A_{total}=12\ cm^2+4\ cm^2$

$A_{total} = 16\ cm^2$

Answer: $A_{total} = 16\ cm^2$
