Answer:
27.1
Step-by-step explanation:
Rounding off to the nearest tenths = the value should be written correctly to <u>one</u> decimal place. The tenth place value in a decimal number is the first number which comes first after the decimal point. For this, we need to observe the hundredth number (the number which comes second after the decimal point). If this number is greater than or equal to 5, we add 1 to the tenth value. If it is less than 5, we leave the tenth place value as it is, and remove all the numbers present after this number.
Answer:
x = 
Step-by-step explanation:
The question states that it is the square root of the sum of both n and 6. That means n and 6 are added first before square rooted. Between B and C, choose the answer that has the parenthesis around x and 6, like (x + 6).
2^6=2*2*2*2*2*2=64
Since the exponent is negative, we put the 64 over 1
1/64
a. If you double both sides, you'll get a rectangle with dimensions 20 feet wide and 30 feet long, therefore the area will be 20 × 30 = 600 feet².
b. The area of the old rectangle was 10 × 15 = 150 feet², so no the area is not twice as large, it is 4 times as large. This is because if the area is base × height, then doubling both of these gets you (2 × base) × (2 × height) = 4 × (base × height).
I hope this helps!
Answer:
Below in bold.
Step-by-step explanation:
Radius of the pizza = 1/2 * 8 = 4 in.
Area of the whole pizza = π r^2
= π * 4^2
= 8 π
So if you take 1/8 away
the area left = 7/8 * 8 * π
= 7π
Taking π to be 22/7:
= 7 * 22/7
= approximately 22 in^2.
