Answer:

38.5

Step-by-step explanation:

Lets say, first number = x


Second number = 3x+7


Total = 49



(x)+(3x+7)= 49


4x+7 = 49


4x = 42


x = 42/4


x= 10.5



x= 10.5


3x+7 = 3(10.5)+7 = 38.5

Circle 1 has a diameter of 18 and circle 2 has a diameter of 20.
borishaifa [10]

Answer:

D. 59.66

Step-by-step explanation:

The formula is <em>A = \pi r^{2}[/tex\ Also the radius is half of the diameter. and [tex]\pi = 3.14</em>

so we need to find the area's

9 x 9 = 81

81 x 3.14 = 254.34

Next circle.

10 x 10 = 100

100 x 3.14 = 314

How does adding a solute ( use only one - salt or sugar) effect the time of water to change from a liquid to a solid?
Kruka [31]

Answer:

adding salt makes the water freeze slower and evaporate slower too.

Step-by-step explanation:

While pure water freezes at 0°C (32°F), salt water needs to be colder before it freezes and so it usually takes longer to freeze. The more salt in the water, the lower the freezing point.
