80+10x is the expression. To find the cost for 9 guests, simply plug in 9 for x. This becomes an equation reading 80+10(9)=170. The total cost for 9 guests is $170.00.

In the triangle below the value of h is 3/4 the side length labeled on the figure. What is the area of the triangle ?
Molodets [167]
I'm not sure if this is the answer, but this is how I solved it. 
A= 1/2 bh (area of a triangle) (1/2 times base times height)
A=1/2 * 3/4
A=3/8?
Do have the picture of the triangle by any chance?

rosijanka [135]

Answer:

5C1 (9C3) (5C3)

And replacing we got:

\frac{5!}{1! 4!} (\frac{9!}{3! (9-3)!}) (\frac{5!}{3! (5-3)!}) = 5*84*10=4200

So then we have a total of 4200 possibilities in order to have a veggle wrap

Step-by-step explanation:

For this case we can use the combinatory formula given by:

nCx= \frac{n!}{x! (n-x)!}

And for this case we have a total of 9 vegatables and 5 condiments and 5 types of tortilla. Then the total number of possibilities are:

5C1 (9C3) (5C3)

And replacing we got:

\frac{5!}{1! 4!} (\frac{9!}{3! (9-3)!}) (\frac{5!}{3! (5-3)!}) = 5*84*10=4200

So then we have a total of 4200 possibilities in order to have a veggle wrap

1. The ratios of the measures of the angles of a triangle are 3:4:11. What is the measure of the largest angle?
lora16 [44]

Answer:

1. 110 degrees.

2.  276 students.

Step-by-step explanation:

1.  Converting the ratios to fractions:

3 + 4 + 11 = 18  so the largest angle is 11/18 of 180 degrees.

Answer is 180 *  11/ 18 = 110 degrees.

2.   That would be 460 * 36 / 60

= 276 students.

Your making a mosaic design on a square table top. You have already covered half of the table top with 150 1-inch square tile pi
Luden [163]
Since this table top is a square, we would expect it to have the same sides. So if your halfway, we can add another 150 1-inch square tile pieces, which makes it 300 inches (150 + 150 = 300; then multiplied by 1 inch).

(a) The dimension can be described using length and width values. So, its dimension is 300 x 300 inches.

(b) The diagonal from one corner to the opposite corner is calculated using the formula: d= √2a, where a represents the measurement of 1 side. Using the values and formula, the diagonal therefore measures 424.26 inches.
