38.5 centimeters squared
44.0 centimeters squared
150.0 centimeters squared
153.9 centimeters squared
The area of a circle is πr². We know r is 7, so the area is π * 7² = 49π.
Substituting, we have 49 * 3.14 = 153.86, which rounds to 153.9 centimeters squared.
The area of circle with a radius of 7 cm is,
⇒ 153.9 centimeters squared
What is mean by Circle?The circle is a closed two dimensional figure , in which the set of all points is equidistance from the center.
We have to given that;
Radius of circle = 7 cm
Now, We know that;
Area of circle is,
A = πr²
Where, 'r' is radius of circle.
Here, Radius of circle = 7 cm
Hence, The area of circle with a radius of 7 cm is,
⇒ A = πr²
⇒ A = 3.14 × 7²
⇒ A = 3.14 × 49
⇒ A = 153.9 centimeters squared
Thus, The area of circle with a radius of 7 cm is,
⇒ 153.9 centimeters squared

gently states that the distance between R(-8,-3.5) and S(-8,-12) is |-12| + |-3.5| = 15.5 units. is Bentley correct? explain your answer. if Bentley is not correct, explain how to find the correct distance between the points
Answer:
No he is not correct.
Step-by-step explanation:
Both points lie at point -8. Knowing this, we also know that to find the answer we would subtract the two coordinates not add them. We do this because they lie in the same quadrant. Therefore, | 12 | - | - 3.5 | = 8.5 units apart.

Explain hard to tell whether (2,-1) is a solution of the equation Y= 3X -2 without using the graph
Answer:
Considering the equation given:
[tex]y= 3x -2[/tex]
As a function:
[tex]f(x)= 3x -2[/tex]
[tex]$(2, -1)$[/tex] states for [tex](x, y)[/tex], which means, [tex]x=2[/tex] and [tex]y=-1[/tex]
[tex]f(2)= 3(2) -2\\f(2)= 6-2\\f(2)= 4[/tex]
[tex]4\neq -1[/tex]
Therefore, [tex]$(2, -1)$[/tex] is not a solution for the equation given and for the function.
Final answer:
To determine if (2,-1) is a solution of Y = 3X - 2, we substitute x=2 into the equation and simplify. The resulting y-value does not match the y-coordinate of the point, therefore (2,-1) is not a solution.
Explanation:
To verify whether the point (2,-1) is a solution to the equation Y = 3X - 2, we need to substitute the x-value of the point (2) into the equation and see if the resulting y-value equals the y-value of the point (-1). If they match, then the point is a solution of the equation.
Let's go through the step-by-step process:
Substitute the x-coordinate of the point into the equation: Y = 3(2) - 2.Simplify the right side of the equation: Y = 6 - 2 which equals 4.Compare this value to the y-coordinate of the point, which is -1.Since the calculated y-value (4) does not equal the y-coordinate of the point (-1), the point (2,-1) is not a solution of the equation Y = 3X - 2.
Which of the following is NOT a perfect square?
A) 49x^2
B) 64a^2
C) 121y^2
D) 125z^2
Answer:
d) 125z^2
Step-by-step explanation:
A perfect square is a number gotten by square an integer e.g. 4 = 2^2, 9 = 3^3. So, 4 and 9 are perfect squares.
lets take each option
a) 49x^2 = 7^2 * x^2 This is a perfect square
b) 64a^2 = 8^2 * a^2 This is a perfect square
c) 121y^2 = 11^2 * y^2 This is a perfect square
d) 125z^2 = (10^2 + 5^2) * z^2 This is not a perfect square

a. How much money do you have left if you ride each ride once?
You have $
left.
b. Do you have enough money to ride each ride twice? Explain.
It costs $
to ride each ride once, and you have $
left.
Question 2
response - correct
To find out how much money you have left after riding each ride once, subtract the total cost of all the rides from the amount of money you have. To find out if you have enough money to ride each ride twice, multiply the cost of each ride by 2 and check if it is less than or equal to the amount of money you have.
Explanation:a. To determine how much money you have left if you ride each ride once, you need to know the cost of each ride. Let's say each ride costs $3. To find out how much money you have left, you subtract the total cost of all the rides ($3 x number of rides) from the amount of money you have. So, in this case, you have $15 - ($3 x number of rides) left.
b. To determine if you have enough money to ride each ride twice, you multiply the cost of each ride by 2 and check if it is less than or equal to the amount of money you have. So, if each ride costs $3, you would calculate $3 x 2 = $6 to see if it is less than or equal to $15.

Simplify the expression. (x1/2y1/3)(x1/4y1/6) A) x1/2y1/2 B) x1/8y1/18 C) x2y2 D) x3/4y1/2
Answer:
[tex](D)x^{3/4}y^{1/2}[/tex]
Step-by-step explanation:
We are required to simplify the expression: [tex](x^{1/2}y^{1/3})(x^{1/4}y^{1/6})[/tex]
This is a product and the first thing we will do is to collect like terms:
[tex](x^{1/2}y^{1/3})(x^{1/4}y^{1/6})=x^{1/2}x^{1/4}y^{1/3}y^{1/6}[/tex]
Next, we apply the addition law of indices: [tex]x^a X x^b =x^{a+b}[/tex]
[tex]x^{1/2}x^{1/4}y^{1/3}y^{1/6}=x^{1/2+1/4}y^{1/3+1/6}\\\\=x^{3/4}y^{1/2}[/tex]
Therefore, [tex](x^{1/2}y^{1/3})(x^{1/4}y^{1/6})=x^{3/4}y^{1/2}[/tex]

-8 (4 - 4a) -2 = 222
Answer:
a = 8
Step-by-step explanation:
-32 + 32a -2 = 222
-34 + 32a = 222
32a = 256
a = 8
Answer:
[tex]a = 8[/tex]
Step-by-step explanation:
Step 1: Distribute
[tex](-8 * 4) + (-8 * -4a) - 2 = 22[/tex]
[tex]-32 + 32a - 2 = 222[/tex]
Step 2: Combine
[tex](-32 - 2) + 32a = 222[/tex]
[tex]-34 + 32a = 222[/tex]
Step 3: Add 34 to both sides
[tex]-34 + 32a + 34 = 222 + 34[/tex]
[tex]32a = 256[/tex]
Step 4: Divide both sides by 32
[tex]32a / 32 = 256 / 32[/tex]
[tex]a = 8[/tex]
Answer: [tex]a = 8[/tex]
