This is showing a corresponding pair of angles. So x would equal 34 degrees. (If it was a linear pair, it would be 180-34)

Westfalls is 7 miles south of edenville and Concord is 13 mile west of westfalls. What is the distance from edenville to Concord

Lelu [443]

Answer:

$D_x\approx14.8mile$

Step-by-step explanation:

From the question we are told that

Distance between Edenville and Westfalls $D_1=7$

Distance between Westfalls and Concord $D_2=13$

Generally the equation for Pythagoras is mathematically given by

$D_x^2=D_1^2+D_2^2$

$D_x^2=7^2+13^2$

$D_x=\sqrt{ 7^2+13^2}$

$D_x=14.76482306mile$

The distance b/w Edenville to Concord is

$D_x\approx14.8mile$

The Hendersons went on a driving vacation. They decided to travel 1/3 of the distance on the first day. Owing to bad weather, th

Sloan [31]

Answer:

$\displaystyle \frac{1}{12}$

$\displaystyle \frac{3}{5}$

$\displaystyle \frac{17}{24}$

Step-by-step explanation:

Part A)

The Hendersons were traveling 1/3 of the distance on the first day.

However, they had to stop, having only traveled 1/4 of the 1/3 distance.

So, we can multiply the two fractions together.

Therefore, the fraction of the total distance they traveled is given by:

$\displaystyle \frac{1}{4}\times\frac{1}{3}=\frac{1}{12}$

The Hendersons traveled 1/12 of the total distance.

Part B)

We are assuming the bottle of milk was full at the beginning.

So, at the beginning, there were 1/1 bottle of milk left.

Howie fed a piglet 1/5 of the bottle. So, there is now:

$\displaystyle 1-\frac{1}{5}$

Of the bottle left.

Making common denominators and subtracting yields:

$\displaystyle =\frac{5}{5}-\frac{1}{5}=\frac{4}{5}$

So, after feeding the piglet, 4/5 of the bottle of milk was still there.

3/4 of the remainder was fed to a calf.

So, the amount that was fed to the calf is 3/4 times 4/5. Therefore:

$\displaystyle \frac{3}{4}\times\frac{4}{5}$

Multiply:

$\displaystyle =\frac{12}{20}=\frac{3}{5}$

So, the calf drank 3/5 of the bottle of milk.

Part C)

Nathan used 2 (5/6) loaves of bread to make 4 sandwiches.

First, convert 2 (5/6) to an improper fraction. So:

$\displaystyle 2\frac{5}{6}=\frac{12+5}{6}=\frac{17}{6}$

Nathan made 4 sandwiches using this. So, we will divide this by 4. Note that this is the same as multiplying by 1/4. Therefore:

$\displaystyle \frac{17}{6}\times\frac{1}{4}=\frac{17}{24}$

So, Nathan used 17/24 loaves of bread per sandwich.
