So rounding to the nearest unit means replacing the number and taking the closest integer it is to. For example 0.96 is 1, and 5.45 is 5. So doing this in this prob. is 1 × 10 × 5, or 50.
1) Cancel out the common factor which in this case is 8 
2)First apply exponent rule
now cancel out the common factors which are n and n+7 leaving you with 
3)Factorize
cancel out the common factor in this case x+2 leaving you with 
4) Factorize
cancel out the common factor in this case 3w-1 leaving you with

Answer:94.2 m
Step-by-step explanation:
Answer:
Each golf ball costs about <u>$2</u>.
Step-by-step explanation:
Given:
Donald bought a box of golf balls for $9.27. There were 18 golf balls in the box.
Rename the decimal dividend as a whole number that is compatible with the divisor to estimate the quotient.
Now, to find the cost of each golf ball.
<u>As given:</u>
<em>Rename the decimal dividend as a whole number that is compatible with the divisor to estimate the quotient.</em>
As, the cost of golf ball box = $9.27.
So, 9.27 nearest to whole number is 9.
Thus to get the cost of each ball:
18 golf balls cost = $9.
So, 1 golf ball cost = 
Therefore, each golf ball costs about $2.
Answer:
9feet
Step-by-step explanation:
Given the path of the toy modeled by the function f(x)=−x^2+4x+5, where x is the number of feet the toy is from Emmy and f(x) is the height of the toy.
AT maximum height, the velocity of the toy will be zero. Hence;
df(x)/dx = 0
-2x + 4 = 0
-2x = -4
x = -4/-2
x = 2
Get the maximum height;
Substitute x = 2 into the given function;
f(x)=−x^2+4x+5
f(2)=−2^2+4(2)+5
f(2) = -4+8+5
f(2) = 9feet
Hence the maximum height of the toy is 9feet
