Answer:
9 feets
Step-by-step explanation:
From the question, we have our scale factor as:
4:9 = 4/9
Smaller circle /Bigger circle = 4/9
A circle has a radius of 4 feet. What is the radius of a bigger circle?
Let the radius of the bigger circle = x
This is calculated as:
4/9 = 4/x
Cross Multiply
4x = 9 × 4
x = 36/4
x = 9 feet
Therefore, the radius of the bigger circle is 9 feet

In a video game, Clare scored 50% more points than Tyler. If c is the number of points that Clare scored and t is the number of points that Tyler scored, which equations are correct? Select all that apply.
c = 1.5t
c = t + 0.5
c = t + 0.5t
c = t + 50
c = (1 + 0.5)t
Answer:
c = t + 0.5t
c = (1 + 0.5)t

(20x^2 – 3x – 9)/(4x – 3)
Answer:
5x+3
Step-by-step explanation:
Rewrite the expression to 20x^2-3x-9/4x-3
Factor 20x^2+12x-15x-9/4x-3
Factor 4x*5x+3-3(5x+3)/4x-3
Factor (5x+3)*(4x-3)/4x-3
Solution then becomes 5x+3 as stated above

Hey please help, I'm pretty sure it's C, but I'm not sure if it's a also
Answer:
It is only C
Step-by-step explanation:
The only answer for this is C
The correct option is option C i.e. "If the ratio of the arc length to r is 1, then the measure of θ is 1 radians".
What is Arc length?The arc length is defined as the interspace between the two points along a section of a curve.
Here, we know that,
angle = arc length / radius ............(i)
If arc length / radius = 1 ............(ii)
then from eq. (i) and (ii), we get
angle = 1
θ = 1
Thus, The correct option is option C i.e. "If the ratio of the arc length to r is 1, then the measure of θ is 1 radians".

Calculate the perimeter of the shape to the nearest whole number
Answer:
Option B
Step-by-step explanation:
Perimeter of the given figure = Sum of measures of all sides
= AB + BC + CA
Since, AB = BC = 9 cm (Radii)
CA = Length of arc CA which is the quarter of the circumference of a circle with radius 9 cm
CA = [tex]\frac{1}{4}(\text{Circumference of the circle})[/tex]
= [tex]\frac{1}{4}(2\pi r)[/tex]
= [tex]\frac{1}{2}(\pi )(9)[/tex]
= 14.14 cm
Now perimeter of the shape = 9 + 9 + 14.14
= 32.14 cm
≈ 32 cm
Therefore, Option B will be the correct option.

What is the domain and range of the inverse of: f (x)= (x + 2)² - 1
Answer:
The inverse of this function is a parabola that has been rotated 90 degrees clockwise, with it's vertex at point 1, 0.
So it's domain is x ≥ 1
And it's range is y ≥ -2
Step-by-step explanation:
Given:
f(x) = (x + 2)² - 1
First we find the inverse:
x = (f(x) + 2)² - 1
x - 1 = (f(x) + 2)²
√(x - 1) = f(x) + 2
f(x) = -2 ± √(x - 1)
PLEASE HELP ME WITH THIS GUYS!!
Answer:
C
Step-by-step explanation:
So they bought 2 sneakers. A pair of sneakers cost $6.49. Multiply that by 2, and you get $12.98.
Then they bought a pair of flip flops. So one pair is $0.99. Add that to the $12.98 you got and now you have $13.97.
They also got a pair of flats. One pair is $7.19, so add that to your $13.97 and you now have $21.16.
They also have to pay $1.75 tax, meaning you add that to the $21.16 you have which makes $22.91 total.
But they said how much change they would get from $30 so we're not done yet. So subtract $22.91 from $30 and your answer will be $7.09 which is C.
8x+ 7y =39
8x + 2y = 34
What is x and y
Answer:
y= 1 and X=4
Step-by-step explanation:
8x +7y =39
8x +2y =34
elimination method(we multiply 8x+7y=39 or 8x + 2y= 34 by -1 to eliminate 8x)
lets multiply 8x+7y = 39 by - 1
-8x -7y = -39
8x +2y = 34
(8x-8x)+(2y-7y)= (-39+34)
0 + (-5y) = -5
-5y= -5......dividing both sides by -5
y = 1
8x +2y =34....... substituting y by 1
8x +2(1)= 34
8x + 2= 34
8x = 34-2
8x = 32.....dividing both sides by 8
x = 4
Lets check;
8x +2y = 34
8(4) +2(1) = 34
32 + 2 =34
34 = 34
8x + 7y = 39
8(4) + 7(1) = 39
32 + 7 =39
39 = 39

Answer:
Unless I am an idiot here (think I am) it is AE s the length between A and E, so it is 8
Step-by-step explanation:
Every side of the square is 16.
A to E is half of a side of the square, not a full side.
So you divide 16 by 2, getting 8.

Answer:
m=-2 b=0
Step-by-step explanation:
first, in order to understand anything, you gotta know what y=mx+b means :)
first, m is just there so you can substitute it for a number. x represents the slope, and b represents the y-intercept, which you also substitute for a number.
so in y= -2x, there's no y intercept, because there is no number that represents the y intercept.
so if we use y=mx+b, we can just substitute the numbers.
which would be, y= -2.
