Priya drew a circle whose area is 25 cm. Dan drew a circle whose diameter is 4 times the radius of Priya's circle. How many time

Vitek1552 [10]

Answer:

400

Step-by-step explanation:

first work out the radius of priya's circle with the equation a = $\pi r^{2}$

$25 = \pi r^{2}$

$\frac{25}{\pi } = r^{2}$

$r = \sqrt{\frac{25}{\pi } }$

we know the diameter of a circle is 2 times the radius so the diameter of priya's circle is 2x $\sqrt{\frac{25}{\pi } }$

this means that if the diameter of dan's circle is 4 times bigger it must be

8x $\sqrt{\frac{25}{\pi } }$

to find the radius of dan's circle we divide the diameter by to 2 to give

4x $\sqrt{\frac{25}{\pi } }$

then use the a= $\pi r^{2}$ equation again

$a= (4 \sqrt{\frac{25}{\pi } })^{2} \pi$

which equals 400

hope that helped

Solve each system of equation by substitution y=-x+5 x+2y=2

Likurg_2 [28]

Answer:

$x = 8$

$y = -3$

Step-by-step explanation:

Given :

$y = -x + 5$ ...................... equation 1

$x + 2y = 2$ ........................ equation 2

solving the system of linear equation by substitution method , substitute equation 1 into equation 2 , that is

$x + 2(-x+5) = 2$

$x - 2x + 10 = 2$

$-x + 10 = 2$

collect the like terms

$10 - 2 = x$

therefore :

$x = 8$

substitute $x = 8$ into equation 1 to find the value of y , that is

$y = -8 + 5$

$y = -3$

Therefore :

$x = 8$

$y = -3$

What are like terms? Provide an example with your description. Choose the correct answer below. A. Like terms are terms that ha

ExtremeBDS [4]

Answer:

Option C.

Step-by-step explanation:

We need to find the correct definition of like terms.

Like terms :Two or more terms are called like terms if they have the same variables and same powers.

For example : 4xy and 9xy are like terms.

Option A is incorrect because 3x and 3 are not like terms.

Option B is incorrect because 6x and 9 are not like terms.

Option C is correct because like terms are terms that have the same variable factors as well as the same number of factors of each type. For example, 3x and 5x are like terms.

Option D is incorrect because 3x and 5 are not like terms.

Therefore, the correct option is C.
