Perimiter=x+y+z
x is 9 times as long as y
z is 1 longer than x

translate
x=9 times y or x=9y
z=1+x
subsitute 9y for x in the z=1+x equation
z=1+9y
subsitute z=1+9y and x=9y in the equation
9y+y+1+9y=39
add like terms
19y+1=39
subtract 1 from both sides
19y=38
divide by 19
y=2
subsitute
x=9y
x=9(2)
x=18

z=1+9y
z=1+9(2)
z=1+18
z=19

the side legnths are
first side: 2 in
second side: 18 in
third side: 19 in

A new car is available with standard or automatic transmission, two or four doors, and it is available in 10 exterior colors. Wh
dezoksy [38]

Answer:

<em>40</em>

Step-by-step explanation:

Given that:

Number of options available for transmission = 2 (Standard or Automatic)

Number of options for doors = 2 (2 doors or 4 doors)

Number of exterior colors available = 10

To find:

Total number of outcomes = ?

Solution:

First of all, let us calculate the number of outcomes for the transmission mode and number of doors options.

1. Standard - 2 doors

2. Standard - 4 doors

3. Automatic - 2 doors

4. Automatic - 4 doors

Number of outcomes possible = 4 (which is equal to number of transmission mode available multiplied by number of doors options i.e. 2\times 2)

Now, these 4 will be mapped with 10 different exterior colors.

Therefore total number of outcomes possible :

Number of transmission modes \times Number of doors options  \times Number of exterior colors

2 \times 2 \times 10 = <em>40</em>

Olin [163]

Step-by-step explanation:

as you know, there are 12 months per year.

also, the word "annual" means "per year" (of again 12 months).

each worker gets 7,576 per month.

that means each worker gets an annual salary of

7,576 × 12 = 90,912

the salaries/wages of all 53 workers together in a year are then

90,912 × 53 = 4,818,336
