You put 15 over 65 is equal to 50 over x, then you multiply diagonally so 15x = 3250 then you divide both sides by 15 to get 216.67 which means 50 pencils equals 2.17 dollars

Citrus2011 [14]

♥ Solve:
(Arjun) 40*30=1200
(Dalia) 55*30=1650
Now subtract
1650-1200=450.
That means that Dalia will type 450 minutes more.
Final answer: 450

What is the APPROXIMATE circumference of a circle with a radius of 9 inches? Use 3.14 for π. 28.3 in. 56.5 in. 254.34 in. 113.0

Stella [2.4K]

Answer:

56.52 in

Step-by-step explanation:

Circumference Formula: C = 2πr

Since we are given radius <em>r</em> = 9, simply plug it into the formula:

C = 2π(9)

C = 18π

C = 56.5487

Point E is located at (−1, 6) and point F is located at (3, 9)

Mars2501 [29]

Answer:

$(x,y)=(\frac{7}{5},\frac{39}{5})$

Step-by-step explanation:

We have given:

E is (-1,6) and F is (3,9)

And ratios are 3:2

We will use the section formula to find the required coordinates:

section formula= $(\frac{m_1x_2+m_2x_1}{m_1+m_2},\frac{m_1y_2+m_2y_1}{m_1+m_2})$

Here, $m_1=3,m_2=2,x_1=-1,x_2=3,y_1=6,y_2=9$

On substituting the values in the formula we get:

$(x,y)=(\frac{3\cdot 3+2\cdot (-1)}{3+2},\frac{3\cdot 9+2\cdot 6}{3+2})$

$\Rightarrow (x,y)=(\frac{9-2}{5},\frac{27+12}{5}$

$\Rightarrow (x,y)=(\frac{7}{5},\frac{39}{5})$

Hence, required coordinates are: $(x,y)=(\frac{7}{5},\frac{39}{5})$
