A car care company sells 45-in. Upholstery fabric for car restoration. Art bought 9 7/12 yd and 11 13/16 yd for two car projects

kvv77 [185]

Answer:

$21\frac{19}{48}\ yards$

Step-by-step explanation:

Art bought $9\frac{7}{12}$ and $11\frac{13}{16}$ yards of fabric.

Total fabric bought: $9\frac{7}{12} + 11\frac{13}{16}$

To add both fractions, we convert them into improper fractions (multiply denominator with whole number, then add the numerator) and then we find the LCM of the two denominators: 12 and 16

LCM of 12 and 16 = 48

$\frac{115}{12} + \frac{189}{16}\\\\\frac{460}{48} + \frac{567}{48}\\\\\frac{460 + 567}{48}\\\\\frac{1027}{48}$

We reduce this fraction to mixed fraction (or reduce if possible), since 1027 and 48 have no common factors.

= $21\frac{19}{48}$ yards

Which relationship between x and y in the equation shows a proportional relationship?

denis23 [38]

Yap,

It seems to me that there are two answers. Both y = .5x and y = 12x. Direct variation is what I'm thinking of so hopefully this helps.

BTW - with Direct Variation, the line will go through (0, 0).

How long would you need to earn interest on $350 invested at 5.5% in order to earn $154 in interest

Fed [463]

Answer:

8 years.

Step-by-step explanation:

The simple interest formula is principal × rate (as a decimal) × time = interest. In this question, you want to find the time.

First, plug in your numbers. 350 × .055 × t = 154. Then, to find t, divide to get t one side.

t = 154 / 350 × .055

Then solve.

350 × .055 is 19.25. 154 / 19.25 is 8.

So, your answer is 8 years.

154/350*.055 = t

Which of the following expression is equivalent to (x+y)^2 ? There more than one correct answer.

Sedbober [7]

Answer:

B, C, E

Step-by-step explanation:

$Option A,\\x^2 + y^2$

If we were to consider expanding the expression ( x + y )^2, take a look at the procedure below;

$( x + y )^2 =\\( x + y )( x + y ) =\\x^2 + xy + yx + y^2 =\\\\x^2 + 2xy + y^2 \neq x^2 + y^2$

Thus, the first option is incorrect

$Option B,\\( y + x )^2 =\\( y + x )( y + x ) =\\y^2 + yx + xy + x^2 =\\\\x^2 + 2xy + y^2$

x^2 + 2xy + y^2 is similar to the result of the expansion of ( x + y )^2, so the second option is correct

$Option C,\\x( x + y ) + y ( x + y ) =\\( x + y )( x + y ) =\\\\( x + y )^2$

Grouping like terms, x( x + y ) + y( x + y ) = ( x + y )^2, and thus the third option is correct

$Option D,\\( x - y )^2 =\\( x - y )( x - y ) =\\x^2 - xy - yx + y^2 =\\\\x^2 - 2xy + y^2 \neq x^2 + 2xy + y^2$

As noted before, x^2 - 2xy + y^2 is not x^2 + 2xy + y^2, so the fourth option is incorrect

$Option E,\\( x + y )^2 = ( x + y )( x + y )$

And thus, Option E is correct!
