First, we'll find the area of the large section, including the smaller section that is white.
Area of a circle: pi x r^2
A = pi x 7^2
A = 49pi x 120/360
A = 49/3 pi cm^2
Now, we'll find the area of the small section.
A = pi x 3^2
A = 9 pi x 120/360
A = 3pi cm^2
All that's left to do now is subtract.
49/3 pi - 3 pi
40/3 pi cm^2
(or 13 1/3 = 13.33 cm^2)
Hope this helps!
Answer:
2x + y = 3.75
3x + 2y = 6
Step-by-step explanation:
x = cost of 1 hot dog
y = cost of 1 drink
Neveah: 2x + y = 3.75
Jason: 3x + 2y = 6
Answer:
0.09 OR 9% is her tax
Step-by-step explanation:
Deborah has to pay 9% for tax. So is someone worked on her computer for two hours then she pays 9% on $120 worth of work. So her tax amount would be $10.800 and her total amount would be 10.8 +120 = $130.80.
Since you know x is between 4 and 5, lets start in the middle using 4.5 for x
4.5^3 - 5(4.5) = 68.625 ( this is larger than 59, so we know the number is less than 4.5)
lets try 4.2: 4.2^3 -5(4.2) = 53.088 ( this is smaller than 59, so we know the number is larger than 4.2)
4.3: 4.3^3 -5(4.3) = 58.007
4.4: 4.4^4 -5(4.4) = 63.184
so we know the answer is between 4.3 and 4.4
4.32: 4.32^3 - 5(4.32) = 59.02 round to 59.0 ( to 1 decimal place)
I think this is what the teacher wants for an answer.
