Answer:

15/8 simplified = 1 7/8

Step-by-step explanation:

an easier way to divide fractions is to convert all into a improper fraction like this 1 1/4 > 1x4+1= 5/4 since 2/3 isnt mixed keep it ok so now you have 5/4 divided by 2/3 next you take the fraction on the right and flip then multiply it to get 5/4 x 3/2 then you multiply across to get 15/8 then change that to a mixed number by dividing 15 by 8 to get 1 with a remainder of 7 so 1 7/8 is your answer

hope this helps you in the future have a blessed day!

Evaluate for x = 3 and y = 4: x^-2y^2/x^0y^3 1/36 4/9 1024/9

GrogVix [38]

Answer:

$\frac{1}{36}$

Step-by-step explanation:

Evaluating the numerator and denominator before evaluating

Using the rule of exponents

$a^{-n}$ ⇔ $\frac{1}{a^{n} }$ , $a^{0}$ = 1

Thus

$x^{-2}$ y² ← substitute values into expression

= $3^{-2}$ × 4² = $\frac{1}{9}$ × 16 = $\frac{16}{9}$

and denominator

$x^{0}$ $y^{3}$ = 1 × 4³ = 1 × 64 = 64

Now dividing

$\frac{16}{9}$ ÷ 64

= $\frac{16}{9}$ × $\frac{1}{64}$ ( cancel 16 and 64 )

= $\frac{1}{9(4)}$ = $\frac{1}{36}$

Kirti has developed formulas to help her determine the size of her rectangular flower garden each spring. If she wants to plant

Ksju [112]

Answer:

A(n) = L(n) × W(n) and $A(n)=0.5n^{2} +2n+2$

Step-by-step explanation:

We are given that the length of the rectangular garden is L and width is W.

Also, in terms of 'n',

Length is given by, L(n) = n + 2

Width is given by, W(n) = 0.5n + 1.

Now, we know that, Area of rectangle = Length × Width.

Therefore, area of Kirti's garden is given by, A(n) = L(n) × W(n).

Thus, formula of area in terms of L(n) and W(n) is A(n) = L(n) × W(n).

Moreover, as A(n) = L(n) × W(n).

i.e. A(n) = (n+2) × (0.5n+1)

i.e. $A(n)=0.5n^{2} +n+2 \times 0.5n+2$

i.e. $A(n)=0.5n^{2} +n+n+2$

i.e. $A(n)=0.5n^{2} +2n+2$

Hence, the formula for area in terms of 'n' is $A(n)=0.5n^{2} +2n+2$ .

What is n (6.5=-3+n) plz help

Tresset [83]

Answer:

n=−0.545455

Step-by-step explanation:

n(6.5)=−3+n

Simplify both sides of the equation.

n(6.5)=−3+n

6.5n=−3+n

6.5n=n−3

Subtract n from both sides.

6.5n−n=n−3−n

5.5n=−3

Divide both sides by 5.5.

5.5n

5.5

=

−3

5.5
