Step One

Change to improper fractions.

1 3/11 = 14/11

1 3/4 = 7/4

Step Two

Find the common denominator

11 = 11 * 1

4 = 2 * 2

The common denominator = 11 * 2 * 2 = 44

Step 3

change the improper fractions to the common denominator.

$\dfrac{14}{11} = \dfrac{14 * 4}{11 * 4} = \dfrac{56}{44}$

$\dfrac{7}{4} = \dfrac{7 * 11}{11 * 4} = \dfrac{77}{44}$

$\dfrac{56}{44}-\dfrac{77}{44} = \dfrac{-21}{44}$

-21/44 That has to be your final answer.

1. Suppose y varies directly with x, and y = 14 when x = -4. What is the value of y when x = -6

In-s [12.5K]

direct variation

y = kx

substitute in and solve for k

14 = k(-4)

14/-4 =k

k = -7/2

y = -7/2 x

y = -7/2 * -6

y = 42/2 = 21

(8CQ) Find the sum of the geometric series. <br> 20-10+5-5/2+...

Ivahew [28]

Answer:

b. $\frac{40}{3}$

Step-by-step explanation:

The given geometric series is;

$20-10+5-\frac{5}{2}+...$

The first term of this series is

$a_1=20$

The common ratio is

$r=\frac{-10}{20}=-\frac{1}{2}$

The sum to infinity of this series is

$S_{\infty}=\frac{a_1}{1-r}$

Substitute the given values to obtain;

$S_{\infty}=\frac{20}{1--\frac{1}{2}}$

This implies that;

$S_{\infty}=\frac{20}{\frac{3}{2}}$

$S_{\infty}=\frac{40}{3}$

John wants to measure the height of a tree. He walks exactly 100 feet from the base of the tree and looks up. The angle from the

kenny6666 [7]

Answer:

The height of the tree is $64.94\ ft$

Step-by-step explanation:

Let

y ----> the height of the tree

we know that

$tan(33\°)=y/100$ ----> the function tangent is equal to divide the opposite side angle of 33 degrees by the adjacent side angle of 33 degrees

Solve for y

$y=(100)tan(33\°)=64.94\ ft$
