Answers
Answer:
58 seconds
Step-by-step explanation:
100 meters in all
Exact calculations:
There are 2 half parts and first half in 27.8 seconds and second in 30.12 seconds so in all it took 27.8+30.12 = 57.92 seconds
Best estimates
27.8 ≈ 28
30.12 ≈ 30
Lily swims a 100 meter race in about 28+30 = 58 seconds

It fell 6 degrees every minute
Since we are talking about temperature dropping, it is negative
-6 degrees each minute

The student's conclusion is incorrect because there is exactly one solution to the equation and this can be determined by using the arithmetic operations.
GIven :
A student concluded that 8x - 12 = 4( 1/2x - 6 ) has infinity many solutions.
The following steps can be used in order to determine the statement that describes the student's conclusion:
Step 1 - Write the given linear equation.
[tex]8x - 12 = 4 (\dfrac{1}{2}x-6)[/tex]
Step 2 - Simplify the above equation.
8x - 12 = 2x - 24
Step 3 - Subtract 2x on both sides in the above equation.
8x - 2x - 12 = 2x - 2x - 24
6x - 12 = -24
Step 4 - Add 12 on both sides in the above equation.
6x - 12 + 12 = 12 - 24
6x = -12
Step 5 - Divide by 6 on both sides in the above equation.
x = -2
Therefore, the correct option is B) The conclusion is incorrect because there is exactly one solution to the equation.

Prove: If two angles are supplementary, then one of the angles must be obtuse.
Which Image provides a counterexample to this statement?
Answers
Answer:
I think it is B
Step-by-step explanation:
Angle AMB is not more than 90 and less than 180 degrees, and neither is angle BMC. Therefore, neither angle is obtuse.
In [tex]\angle[/tex] A, [tex]\angle[/tex] BMC is an obtuse angle.
In [tex]\angle[/tex] B, [tex]\angle[/tex] AMB is an obtuse angle.
In [tex]\angle[/tex] D, [tex]\angle[/tex] AMB is an obtuse angle.
But, in C there are two right angles
Therefore, two right angles exist supplementary.
What is a supplementary angle?When the sum of the measures of two angles is 180°, such angles are called supplementary angles and each of them is called a supplement of the other.
Two angles exist named supplementary when their measures count up to 180 degrees. By the explanation of obtuse angles, the angles that estimate more significant than 90° exist as obtuse. If we add two obtuse angles, the sum will be more significant than 180°. It will not help the results of the supplementary angles when we add obtuse angles.
In [tex]\angle[/tex] A, [tex]\angle[/tex] BMC is an obtuse angle.
In [tex]\angle[/tex] B, [tex]\angle[/tex] AMB is an obtuse angle.
In [tex]\angle[/tex] D, [tex]\angle[/tex] AMB is an obtuse angle.
But, in C there are two right angles
The two right angles exist supplementary.
Therefore, the correct answer is option B.
