Answer:

$128

Step-by-step explanation:

1. We need to find how much 1 yard of material cost.

If needed, use a calculator*

120/75=1.6

2. Now we need to know how much 15 yards of material cost.

1.6 times 15=24

3. The buyer ordered an additional 90 yards. If we know how much 75 yards cost, and 15 yards, all you have to do is...

120+24=144

90 yards=$144

4. The additional cost is $144

(Note: the total cost would be $264 (120+144=264))

Dario bakes a lasagna containing $\frac 23$ pound of parmesan cheese, $1\frac 14$ pounds of ricotta cheese, and $1\frac 13$ poun

svp [43]

Answer: There are 13 slices when Dario cuts .

Explanation :

Since we have given that

Quantity of parmesan cheese is given by

$\frac{2}{3}$

Quantity of ricotta cheese is given by

$1\frac{1}{4}$

Quantity of mozzarella cheese is given by

$1\frac{1}{3}$

Now, total quantity of cheese Dario have

$\frac{2}{3}+\frac{5}{4}+\frac{4}{3}=2+\frac{5}{4}=\frac{8+5}{4}=\frac{13}{4}$

Now,

According to question, Dario cuts the lasagna into several equal slices and each containing exactly

$\frac{1}{4}\ pounds\ of\ cheese$

So,

Number of slices is given by

$\frac{\frac{13}{4}}{\frac{1}{4}}=13$

Hence, there are 13 slices when Dario cuts .

Solve the rational equation x divided by 6 equals x squared divided by quantity x minus 1 end quantity, and check for extraneous

Dmitriy789 [7]

Answer:

Solution: $x=-\frac{1}{5}$ , $x=0$

Step-by-step explanation:

Given:

The rational equation to solve is given as:

$\frac{x}{6}=\frac{x^2}{x-1}$

Doing cross product, we get:

$x\times (x-1)=6\times x^2\\x^2-x=6x^2\\\textrm{Bringing all variables to the right side, we get:}\\6x^2-x^2+x=0\\5x^2+x=0\\x(5x+1)=0\\x=0\ or\ 5x+1=0\\x=0\ or\ x=-\frac{1}{5}$

Now, for $x=0$ , the rational equation is equal to 0. So, $x=0$ is a solution.

Also, $x=-\frac{1}{5}$ is also a solution.

So, no extraneous solution.

4 + 12/13 = 64/13
4 + 19/20 = 99/20
4 + 26/27 = 134/27
4 + 33/34 = 169/34
4 + 40/41 = 204/41

top: 64, 99, 134, 169, 204
bottom: 13, 20, 27, 34, 41

top:
35(1) + 29 = 64
35(2) + 29 = 99
35(3) + 29 = 134
35(4) + 29 = 169
35(5) + 29 = 204

bottom:
7(1) + 6 = 13
7(2) + 6 = 20
7(3) + 6 = 27
7(4) + 6 = 34
7(5) + 6 = 41

answer is C.

35n + 29
