Five out of every nine pencils are yellow. You can make a fraction for this:

\frac{5}{9}

You have 45 pencils. To find the amount of yellow pencils, multiply the fraction by 45. First set up the equation:

\frac{5}{9} \times 45

Make 45 as a fraction so that you'll be multiplying fractions together. It will also make it easier.

To write a whole number as a fraction, <em>ALWAYS</em> make the whole number the denominator and 1 as the numerator.

45 \rightarrow \frac{45}{1}

Here is the "new equation":

\frac{5}{9} \times \frac{45}{1}

Multiply. You multiply the numerators and denominators together.

\frac{5}{9} \times \frac{45}{1} =\frac{225}{9} = 25

That means <u>25</u> pencils are yellow

Given the figure, find the values of x and z.
I am Lyosha [343]

Step-by-step explanation:

  • (8x-38°)=90° {because of being vertically opposite angles}
  • 8x-38°=90°
  • 8x=90°-38°
  • 8x=52°
  • x=52°/8
  • x=6.5°

  • z°+90°=180° {being linear pair}
  • z°=180°-90°
  • z°=90°

Consider F and C below. F(x, y) = x4y5i + x5y4j, C: r(t) = t3 − 2t, t3 + 2t , 0 ≤ t ≤ 1 (a) Find a function f such that F = ∇f.
vovikov84 [41]
\mathbf f(x,y)=x^4y^5\,\mathbf i+x^5y^4\,\mathbf j

We want a scalar function f(x,y) whose gradient is equivalent to the vector field. That means

\dfrac{\partial f}{\partial x}=x^4y^5\implies f(x,y)=\dfrac{x^5y^5}5+g(y)
\dfrac{\partial f}{\partial y}=x^5y^4\implies x^5y^4=x^5y^4+\dfrac{\mathrm dg}{\mathrm dy}
\implies\dfrac{\mathrm dg}{\mathrm dy}=0\implies g(y)=C

So (a)

f(x,y)=\dfrac{x^5y^5}5+C

which means (b)

\displaystyle\int_{\mathcal C}\mathbf f\cdot\mathrm d\mathbf r=f(\mathbf r(1))-f(\mathbf r(0))=f(-1,3)-f(0,0)=-\dfrac{243}5-0=-\dfrac{243}5

Here it is^ algebra 1
Kamila [148]
Is (2,4) a solution for y <= 3x -1 ??
answer : No
x = 2, replace it in the equation
y <= 3(2) - 1
y<= 5
--_(2,5)
y = 4, again replace it in equation
4 <= 3x - 1
3x <= 5
x <= 5/3
--_(5/3,4)
