Answer:
True
Step-by-step explanation:
The <em>first power</em> of the variable is what makes it a <em>linear</em> term.
Answer:
362 kilometre
Step-by-step explanation:
Let a be the total cost of a journey
let b represent the total distance of a journey
$1.75 is a fixed charge of a journey
the additional charge is $0.10 for b distance ,hence total of additional charge is $.10 multiplied by b i.e 0.1 b
a=1.75+0.1b
a =37.90
37.90=1.75+0.1b
0.1b=37.90-1.75
0.1 b=36.15
b=36.15
/0.10
b=361.5
b=362 kilometre
For the journey that cost 21.80
21.80=1.75+0.1 b
0.1 b=21.80-1.75
0.1 b=20.05
b=20.05
/0.1
b=200.5
b =201 kilometre
Answer:
9sqrt(3) in.
Step-by-step explanation:
The ratio of the lengths of the sides of a 30-60-90 triangle is:
short leg : long leg : hypotenuse
1 : sqrt(3) : 2
If the short leg measures 1, then the hypotenuse measures 2.
The length of the hypotenuse is twice the length of the short leg.
The length of the long leg is sqrt(3) times the length of the short leg.
If the hypotenuse measures 18 in., then the short leg measures 9 in.
Then the long leg measures 9sqrt(3) in.
Answer:
for a book that have less than 100 pages, first publishing company is better choice, but for a book with more than 100 pages, second company is cheaper.
Step-by-step explanation:
total pages=p
2p = p+100 -» p=100
FOR EXAMPLE:
for a book with 55 pages: first company cost 100$ and second company cost 155$
for a book with 300 pages: first company cost's 600$ but second company cost's 400$
