Quantavius took a hiking with some friends.The friend started early and walked a while before stoping to each lunch.After lunch

kifflom [539]

Answer:

$7\frac{3}{8} \ miles$

Step-by-step explanation:

Given:

After lunch the friends walked 6 3/4 miles before arriving at the end of the trail.

The trail is 14 1/8 miles long.

Question asked:

How long did the friends walk before lunch ?

Solution:

Let the friends walk before lunch in miles = $x$

As total length of trail is given $14\frac{1}{8}\ miles$ , we can conclude:

Total length of trail = The friends walk before lunch in miles + The friends walk after lunch in miles

$14\frac{1}{8} =x+6\frac{3}{4} \\ \frac{14\times8+1}{8}=x+\frac{6\times4+3}{4} \\\frac{113}{8} =x+\frac{27}{4}$

Subtracting both side by $\frac{27}{4}$

$\frac{113}{8} -\frac{27}{4} =x+\frac{27}{4}-\frac{27}{4}$

Taking LCM of 4 and 8 ,we get 8

$\frac{113-54}{8} =x\\\\\frac{59}{8} =x\\\ \\7\frac{3}{8} = x$

Therefore, the friends walk before lunch is $7\frac{3}{8} \ miles$ .

Please help!! Double points! write the ratios for sin X and cos X (Image attached)

Orlov [11]

Answer:

The ratio for sin(X) is $\frac{\sqrt{119} }{12}$

The ratio for cos(X) is $\frac{5}{12}$

Step-by-step explanation:

- The ratio of the sine of a right triangle is:

$sin(\alpha)=\frac{opposite-side}{hypotenuse}$

Since we need the ratio for angle X, $\alpha =X$ . From the picture we can infer that the opposite side of X is $\sqrt{119}$ . The hypotenuse (the side opposite to the right angle) is 12, so replacing the values:

$sin(X)=\frac{\sqrt{119} }{12}$

- The ratio of the cosine is:

$cos(\alpha)=\frac{adjacent-side}{hypotenuse}$

Similarly, $\alpha =X$ , adjacent side = 5, and hypotenuse = 12, so

$cos(X)=\frac{5}{12}$

the ortiz family is building a barn on a property with a perimeter of 120 meters. what is the area of the property that Mr. Orti

DochEvi [55]

Answer:

900 square meters

Step-by-step explanation:

The property is in the shape of a square.

The perimeter of a square is given as:

P = 4L

where L = length of its side

Therefore, the length of the property is:

120 = 4 * L

L = 120 / 4 = 30 meters

The area of a square is given as:

A = L * L

Therefore, the area of the property is:

A = 30 * 30 = 900 square meters
