Answer: D
Step-by-step explanation:
12 and 14 share the factor 2 so the furthest it can be simplified to is 6/7. this is not equal to 4/7
The 2nd one or either the last one, I suggest the last one hope this helps!!
We are to write the expression for:
<span>The product of two and The sum of a number and eight
</span>
This means 2 is to be multiplied with the sum of 8 and the number. The number is n. So sum of 8 and number is 8 + n
Product of 2 and the sum is 2 (8 + n)
Therefore, the correct answer is option D
Answer:
20.16 meters
82.77º
Step-by-step explanation:
We have that the ramp would have the shape of a rectangular triangle, where the height and width would be the legs and the slope the hypotenuse.
We can solve it by means of the Pythagorean theorem that tells us:
c ^ 2 = a ^ 2 + b ^ 2
a = 2.5 and b = 20, replacing:
c ^ 2 = 2.5 ^ 2 + 20 ^ 2
c ^ 2 = 406.25
c = 20.16
Therefore the slope would be 20.16 meters.
The angle, we will do it using the function: Sin A ° = opposite / hypotenuse
where the opposite is the height, that is to say 20 and the hypotenuse that is the slope is equal to 20.16, replacing:
Without Aº = 20 / 20.16
Without Aº = 0.992
Aº = arc sin (0.992)
Aº = 82.77
Which means that the angle is of the slope with the horizontal is 82.77º
Answer:
Step-by-step explanation:
(17×25)×4=n×(25×4)
or 17×(25×4)=n×(25×4)
17=n
∵ (a×b)×c=a×(b×c) [by associative law of multiplication.]
