Answer:
The first 4 are correct and the last one is incorrect
Step-by-step explanation:
1. The diameter of the circle is 30.8 m ( Correct )
Radius = 15.4 so diameter is 2 times the radius which is 30.8 m
2. The circumference in terms of π is 30.8 π ( Correct )
Circumference = π × Diameter
Circumference = π × 30.8
Circumference = 30.8 π
3 . The circumference of the circle can be found using 2 × π × 15 . 4 ( Correct )
Circumference = π × Diameter
Circumference = π × 30.8
Circumference = 30.8 π
4 . The approximate circumference of the circle rounded to the nearest tenth is 96.7 m ( Correct )
Circumference = 30.8 π = 96.7610537306
5 . A little more than 6 diameters could be wrapped around the circle
( False )
Circumference = 96.7610537306
Diameter = 30 . 8
96.7610537306 ÷ 30 . 8 = 3.14
I can’t write a fraction correctly by typing but the answer is 8/5x
Answer:
40%
Step-by-step explanation:
As a Fraction your answer would be 
.
However we are looking for it as a percentage.
In order to calculate, this you can simply find 10%, and 5% of 120.
10% = 12
5% = 6
48 is divisible by 12, therefore 48 / 12 = 4
Giving you your answer which is 40%.
10/9 is equivalent to 9 parts out of 10 or simply 0.9
There is 2 solutions:
x = 6
x = -7
Step by step solutions-
Reformatting the input :
Changes made to your input should not affect the solution:
(1): "x2" was replaced by "x^2". 1 more similar replacement(s).
Equation at the end of step 1-
(((x3) - 5x2) - 48x) + 252 = 0
Checking for a perfect cube step 2-
2.1 x3-5x2-48x+252 is not a perfect cube
Trying to factor by pulling out :
2.2 Factoring: x3-5x2-48x+252
Thoughtfully split the expression at hand into groups, each group having two terms :
Group 1: x3-5x2
Group 2: -48x+252
Pull out from each group separately :
Group 1: (x-5) • (x2)
Group 2: (4x-21) • (-12)
Bad news !! Factoring by pulling out fails :
The groups have no common factor and can not be added up to form a multiplication.
