Additive inverse of 125 is – 125, option C is correct.
<u>Solution:</u>
Given that , a number is 125
We have to find the additive inverse for the above given number from the above given set of options.
Now, we know that, <em>sum of a number and its additive inverse equals to 0.
</em>
So, let us check option by option.
<em><u>Option A:</u></em>
Given number is -(-125)
-(-125) ⇒ 125 + ( - ( - 125 ) )
⇒ 125 + 125
⇒ 250 ⇒ wrong option
<em><u>Option B:</u></em>
Given number is 125
⇒ 125 + 125 ⇒ 250 ⇒ wrong option
<em><u>Option C:</u></em>
Given number is -125
125 + ( - 125 ) ⇒ 125 – 125 ⇒ 0 ⇒ correct option
Hence, additive inverse of 125 is – 125, option C is correct
Answer:
1 3/4 or 1.75
Step-by-step explanation:
An easy way to do this is to convert to decimals
1/4 = 0.25
2/4 = 0.5
3/4 = 0.75
Now, for the numbers for this problem.
2 3/4 would be equal to 2.75
3 1/2 would be equal to 3.5
Add those two numbers together and you get 6.25
Subtract that from 8 and you get 1.75 or 1 3/4
Answer:
47.0
Step-by-step explanation:
In this right angle triangle, we are faced with a challenge of two sides. The opposite side and the adjacent side, hence the tangent is used.
Where it is the opposite side and hypothenus side, the sine is used and when it is the hypothenus side and adjacent side, the cosine is used.
Hence, we have tan62°=x/25
We cross multiply, to have
25(tan 62°)= x
x = 47.01816
In rounding up numbers, number 1 to 4 will be rounded up to zero, while numbers 5 to 9 will be rounded up to 1.
Rounding up 47.01816 to the nearest tenth. The tenth value is the figure is 0, before it we have 1, which is to hundredth. 1 will be rounded up to zero.
So we have 47.0
Answer:
last option is the answer; all values greater than 12
Step-by-step explanation:
2/3x - 5 > 3
2/3x > 8
x > 24/2
x > 12
