The product of 8 and 5/7 is 5.7
<u>Step-by-step explanation:</u>
The given product is .
<u>In the product, two terms are given :</u>
- The first term 8 is a whole number.
- The second term 5/7 is a fraction.
1) So, to find the product of the first term and the second term, one method is to simplify the fraction into decimal number and then perform multiplication operation.
2) Either you can multiply the two terms in the first step and then the division operation is performed at the final step.
<u>First method :</u>
<u><em>Step 1 :</em></u> Convert the fraction into decimal
⇒ 5/7 = 0.71
<u><em>Step 2 :</em></u> Multiply the result with the other term.
⇒ 8 × 0.71
⇒ 5.68 (approximately 5.7)
<u>Second method :</u>
<u><em>Step 1 :</em></u> Multiply both the terms
⇒ 8 ×(5/7) = 40/7
<u><em>Step 2 :</em></u> divide 40 by 7
⇒ 40÷ 7 = 5.7
Therefore, the product of 8 and 5/7 is 5.7
Answer:
A.
Step-by-step explanation:
We have, the dimensions of the living room are 30 ft and 20 ft.
Thus, area of the living room = length × width = 30 × 20 = 600 ft².
Now, it is given that the cabinet takes 6% of the living room i.e. 6% of 600 ft² = 0.06 × 600 = 36 ft².
As, the triangle has dimensions (2x+3) ft and (3x+6) ft.
So, the area of the triangle =
i.e. Area of cabinet =
i.e. Area of cabinet =
i.e. Area of cabinet =
Since, the cabinet takes 6% of the living room, we have,
= 36
i.e.
i.e.
i.e.
Further, as the solution of a quadratic equation is given by
On comparing we have, a=2, b=7, c= -18.
Thus,
i.e.
i.e.
i.e. and
So, according to the options, we have,
A. is the correct value of x.
