Answer:

3 1/2

Step-by-step explanation:

-3 1/6+6 2/3

We need to get a common denominator of 6

-3 1/6 + 6 2/3 *2/2

-3 1/6 + 6 4/6

Since the signs are different, we subtract and take the sign of the larger number

6 4/6 - 3 1/6 = 3 3/6 = 3 1/2

The sign of the larger number was positive so the answer is positive

3 1/2

You divide both numbers by the greatest common factor, which in this case is the number 8 so the equation would look some what like this
16/8=2
8/8=1
The ratio is 2:1

Wally wants to determine the height of a statue that casts a 164-inch shadow by comparing it to his own height and shadow length

nataly862011 [7]

We have been given that Wally wants to determine the height of a statue that casts a 164-inch shadow by comparing it to his own height and shadow length. Wally is 68 inches tall, casts a shadow that is 41 inches in length.

We will use proportions to solve for the height of the statue because proportions state that ratio between two proportional quantities is same.

$\frac{\text{Height of statue}}{\text{Shadow of statue}}=\frac{\text{Height of Wally}}{\text{Shadow of Wally}}$

Upon substituting our given values in above equation, we will get:

$\frac{\text{Height of statue}}{\text{164 cm}}=\frac{\text{68 inch}}{\text{41 inch}}$

$\frac{\text{Height of statue}}{\text{164 cm}}\times \text{164 cm}=\frac{\text{68 inch}}{\text{41 inch}}\times \text{164 cm}$

$\text{Height of statue}=\frac{\text{68 inch}}{1}\times 4$

$\text{Height of statue}=272\text{ inches}$

Therefore, the height of the statue is 272 inches.

PLEASE HELP, THANK YOU!:

The answer to question 1 is $8.10.

I got this by finding 18% of $45, which I assume is what the server's tax/tip is.

The answer to question 2 is 7.99.

I got this by finding 8.5 percent of 94 dollars, which is the tax.

Hope this helps, if not, comment below please!!!

You can focus on the two sub-triangles ABC and ACD

We know that they are both right triangles, because we're given that AC and BD are perpendicular.

The sides AB and AD are the hypothenuses of these triangles, so we know their length through the pythagorean theorem:

$AD^2 = AC^2+CD^2$

$AB^2 = AC^2+BC^2$

But since we're given $BC=CD$ , the expressions for AD and AB are actually the same expression. This proves that AD=AB, and thus that the triangle is isosceles.
