Answer:
Area of circle A =113.14 mm²
Area of circle b = 314.29 mm²
Area of circle C = 452.57 mm²
Area of circle A = 254.57 mm²
2.25 times
Step-by-step explanation:
Area of a circle = nr²
where n = 22/7
r = radius
Circle A's radius = 6mm
Circle B's radius = 6mm + 4mm = 10mm
Circle C's radius = 10mm + 2mm = 12mm
Circle D's radius = 12mm - 3mm = 9mm
Area of circle A = (22/7) x 6² = 113.14 mm²
Area of circle b = (22/7) x 10² = 314.29 mm²
Area of circle C = (22/7) x 12² = 452.57 mm²
Area of circle A = (22/7) x 9² = 254.57 mm²
Number of times the area of circle D is greater than that circle A = Area of circle D / Area of circle A
254.57 mm² / 113.14 mm² = 2.25 times

An Ice cube right triangle prism. Use the dimensions shown to find the surface area of this ice cube
A) 24 cm²
B) 27 cm²
C) 36 cm²
D) 54 cm²
Answer:
i think its A
Step-by-step explanation:
solve algebraically
1. y = x^2+ 3x - 5
y = x + 3
2. y = x^2- 4x + 6
y = x + 2
3. y = x^2- 10x + 14
y = 7x - 16
4. y = x^2-24
y = x - 12
5. y = x^2- 8x + 28
y = 4x + 8

Answer: The distance from the center of the circle to the edge is
inches,
Answer:
the distance is the radius, so all we have to do is divide 34.8 by 2= 17.4
17.4 inches!

Answer:
170
Step-by-step explanation:
If you look at the other angle it says 20 and a whole circle would be 360 so subtract 360-130 then after that since the angle takes 2 part or however you may say that means u subtract 60 (20+20+20 thee open angle) this means you get 170 (i think im unsure but you can try)
Jim gives the cashier a $20 bill at the pharmacy.
Write an equation that relates the change c he gets back in dollars to the cost b, in dollars, of his purchases. Which variable represents the independent variable? How much change does he get back if his purchases total $12.83?
Answer:
b= 12.83
c= 7.17
Variable "c" is independent because it does not change. Jim receives $7.17 back.

The letters in the word JANUARY were put in a bag and drawn randomly. What is the probability of picking an a?
Answer: 2/7
Step-by-step explanation:
There are 7 letters in January, and 2 "a"s in order to find the probability, simply take 2/7. You can either leave it in the fraction form, or use the calculator, showing you have a 0.2857% chance of picking an "a"
2/7
there are 7 letters in jAnuAry and as you can see there are 2 A's so there is a 2/7 chance which is higher of a chance than the rest of the letters which are 1/7 each so it is most likely you would draw A although I can't fully say that because there is a 5/7 chance of drawing the other letters. Another way to say it is there is a 0.28571428571% chance of drawing A but there is a 0.71428571428% chance of drawing any other letter.
Hope this helps :3

The volume of a cube is 216 cubic meters. What is the length (in meters) of one edge of the cube?
Answer: 6 meters
Step-by-step explanation: 6 is also what we call a cube root of a number. A cube root is a number you multiply by itself 3 times to get the product.
6 times 6 equals 36. 36 times 6 equals 216.
(6 times 6 times 6 = 216)
Look at the question below.
Which equation represents the line that passes through the point (-3, 2) and has a slope of 2?
O y = 2x + 1
O
y = 2x - 4
O y = 2x - 7
y = 2x + 8
Answer:
y = 2x + 8
Step-by-step explanation:
To find the line, use the equation y = mx + b.
Plug in the slope and given point, then solve for b:
y = mx + b
2 = 2(-3) + b
2 = -6 + b
8 = b
Plug in the slope and b into the equation:
y = 2x + 8
So, the equation of the line is y = 2x + 8

The center of a circle is (0, -8). The radius is 9. What is the equation of the circle? Select all that apply.
A. x2 + (y + 8)2 = 3
B. x2 + (y + 8)2 = 9
C. x2 + (y + 8)2 = 81
D. x2 + y2 + 16y = 17
E. x2 + y2 + 16y = -55
Answer:
x² + (y + 8)² = 81
Step-by-step explanation:
Centre (h,k) = (0,-8)
radius (r) = 9
(x - h)² + (y - k)² = r²
(x - 0)² + (y + 8)² = 9²
x² + (y + 8)² = 81

Step-by-step explanation:
AKS 19 -- Dan is driving with an average speed of s. He is driving a total distance of d. What formula represents the total time of his trip? Question 2 options: t=ds t = d s t=ds t=d-s t=sd
Answer:
[tex]t=\dfrac{d}{s}[/tex]
Step-by-step explanation:
Dan is driving with an average speed of s. He is driving a total distance of d.
The average speed of an object is given by :
Average speed = total distance/total time
Let b the time of his trip
So,
[tex]s=\dfrac{d}{t}\\\\or\\\\t=\dfrac{d}{s}[/tex]
So, the formula for the total time of his trip is [tex]\dfrac{d}{s}[/tex].
