Use rounding to estimate the product
sdas [7]

Answer:

The estimate of the product is about 35 answer C

Step-by-step explanation:

- We use rounding to estimate the product of two fractions

- The mixed number has whole number and fraction

- To round the mixed number we look to the fraction

- If the numerator is half or greater than half the denominator, then we

  add the whole number by 1 and cancel the fraction

- If the numerator is less than half the denominator, then we keep the

  whole number as it and cancel the fraction

- Ex: If the mixed number is 2\frac{3}{4}, 3 is more than

 half 4 then we will add 2 by 1 and cancel the fraction part, the

 mixed number 2\frac{3}{4} after rounding is 3

- Ex: If the mixed number is 5\frac{1}{4}, 1 is less than

 half 4 then we will keep 5 as it and cancel the fraction part, the

 mixed number 5\frac{1}{4} after rounding is 5

* Lets solve the problem

∵ In the part 4\frac{3}{4} 3 is more than half 4

∴ The rounding value of 4\frac{3}{4} is 5

∵ In the part 7\frac{2}{17} 2 is less than half 17

∴ The rounding value of 7\frac{2}{17} is 7

∴ 4\frac{3}{4}*7\frac{2}{17}=5*7=35

* <em>The estimate of the product is about 35</em>

C. Tan k=31/24<br> D. Cos k= 31/24
lubasha [3.4K]

Hello!

The sin of D would be the opposite side divided by the hypotenuse. As we have no hypotenuse length, neither A or D would work, as the cosine also involves the hypotenuse.

The tangent is the opposite divided by the adjacent. This would be, in terms of D, 24/31. This does not match our option.

In terms of K, the tangent is 31/24.

Therefore, our answer is C) tanK= 31/24

I hope this helps!
