Answer:

56 degrees

Step-by-step explanation:

The consecutive angles in a parallelogram add up to 180

3x + 8 + 7x + 12 = 180

Then simplify

10x +20 = 180

10x = 160

x = 16

angle q = 3x + 8 = 3(16) + 8 = 48 + 8 = 56

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 )

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

Nutka1998 [239]

Answer:

squaare root of 70<pi squared<10

Step-by-step explanation:

Talking about square root of 70, you can take the answer by approximation. u know square of eight is sixty four and square of nine is eighty one. so 70's square root shluld be between eight and nine. And as the value of pi is 3.14... when square of pi is considerd it should be >9 but <10 as pi>3. So 10 become te greatest

Knowing that the result of expanding (x+a)(x-6) is x²+mx-48, find the values of a and m.

Citrus2011 [14]

We know -48 came from (a)(-6), the "L" in "FOIL".

If -48 = -6a, then a = 8.

Now with a=8, go ahead and FOIL (x+8)(x-6) to find m.
