Answer:

1.6y+y-4/15y+7/6y=21/3

We move all terms to the left:

1.6y+y-4/15y+7/6y-(21/3)=0

Domain of the equation: 15y!=0

y!=0/15

y!=0

y∈R

Domain of the equation: 6y!=0

y!=0/6

y!=0

y∈R

We add all the numbers together, and all the variables

1.6y+y-4/15y+7/6y-7=0

We add all the numbers together, and all the variables

2.6y-4/15y+7/6y-7=0

We calculate fractions

2.6y+(-24y)/90y^2+105y/90y^2-7=0

We multiply all the terms by the denominator

(2.6y)*90y^2+(-24y)+105y-7*90y^2=0

We add all the numbers together, and all the variables

(+2.6y)*90y^2+(-24y)+105y-7*90y^2=0

We add all the numbers together, and all the variables

105y+(+2.6y)*90y^2+(-24y)-7*90y^2=0

Wy multiply elements

-630y^2+105y+(+2.6y)*90y^2+(-24y)=0

We get rid of parentheses

-630y^2+105y+(+2.6y)*90y^2-24y=0

We add all the numbers together, and all the variables

-630y^2+81y+(+2.6y)*90y^2=0

And DVD cost $26.75 before sale tax sale tax is 7.5% what is the total of cost of DVDs

blondinia [14]

First let's convert 7.5% into a decimal by doing Beyoncé on it and move the decimal two places to the left.

$7.5\% = 0.075$

Now let's multiply the cost of the DVD by the converted percent,

$26.75 \times 0.075 = 2.00$
Now let's add the above number to the original price, remember, $2 is not exact.

$26.75 + 2.00 = 28.75$

(8v3-80v2+6)\(v-10)

Leto [7]

$\frac{(8v^3-80v^2+6)}{v-10}$

Use long division for dividing

$(8v^3-80v^2+6)$ Here 'v' term is missing so we use 0vW

Divide $(8v^3-80v^2+0v+6)$ by v-10 using long division

Step 1: Put 8v^2 at the top

step 2: multiply 8v^2 with v-10 and put it at the bottom

step 3: subtract it

We will get remainder 6

so quotient is $8v^2$

Remainder is 6

Solve and simplify<br> 3. (y^2-7y-5)-(-3y^2+3y-4)

yKpoI14uk [10]

$(y^2-7y-5)-(-3y^2+3y-4)=y^2-7y-5-(-3y^2)-3y-(-4)\\\\=y^2-7y-5+3y^2-3y+4$

<em>combine like terms</em>

$=(y^2+3y^2)+(-7y-3y)+(-5+4)=\boxed{4y^2-10y-1}$

A company plans to build a wheelchair ramp with the following

Liono4ka [1.6K]

9514 1404 393

Answer:

yes

Step-by-step explanation:

The height that would be allowed with a ramp 43.5 feet long is ...

h = (43.5 ft)·sin(4.8°) ≈ 3.64 ft

The proposed height is less than 3.64 ft, so the ramp angle is less than 4.8°.

__

The ramp angle is actually arcsin(3/43.5) ≈ 3.95°, which is less than 4.8°.
