lora16 [44]

Answer:

x = 16

Step-by-step explanation:

We know that:

∠1 = ∠2 (Corresponding Angles)
∠1 = 63 - 2x
∠2 = 79 - 3x

Solution:

63 - 2x = 79 - 3x
=> 3x - 2x = 79 - 63
=> x = 16

Hence, the measure of x is 16.

Jin needs 0.8 gram of carbon for an experiment. She needs 4.15 times as much water. Jins says that she needs less than 4.15 gram

natima [27]

Answer:

That is a correct statement.

Step-by-step explanation:

This is because to find the appropriate amount, we would multiply the two numbers together. Since we are multiplying 4.15 by a number less than 1 (0.8), the number can only be lower. The number would only be higher if the number was greater than 1.

What is the area of this circle ( express your answer by using pi)

Leona [35]

Answer: option C

Step-by-step explanation:

You need to use the formula for calculate the area of a circle:

$A_{(circle)}=\pi r^2$

Where the radius of the circle is "r".

You can see in the figure that the diameter of the circle is 6 meters. Then you need to find the radius of the circle with the formula:

$r=\frac{d}{2}$

Where "d" is the diameter of the circle.

Then, the radius is:

$r=\frac{6m}{2}=3m$

Finally, substitute the radius into the formula. Then, the area of the circle is:

$A_{circle}=\pi (3m)^2=9\pi m^2$
