The lengths of three
True [87]

Answer:

90 cm, 180 cm, 240 cm

Step-by-step explanation:

Let the lengths of sides of the triangle be 3x, 6x and 8x

\therefore \: 3x + 6x + 8x = 5.1 \: m \\ \therefore \: 17x = 510 \: cm \\ \therefore \: x =  \frac{510}{17}  \\  \therefore \:x = 30 \: cm \\  \implies \\ 3x = 3 \times 30 = 90 \: cm \\ 6x = 6 \times 30 = 180 \: cm \\ 8x = 8 \times 30 = 240 \: cm

Hence, lengths of the sides of the triangle are 90 cm, 180 cm and 240 cm.

Francois earns a weekly salary of$475 a5.5%commission on sales at a gift shop how much would he earn in a week if he sold $700 g
Ganezh [65]

Answer:

$513.50

Step-by-step explanation:

Francois earns $475 plus 5.5% or 0.055 of whatever sales he makes. If he sells $700 then he makes 0.055(700) = $38.50 in commission.

$475 + $38.50 = $513.50

Amy used a total of 7 1/4 gallons of gas while driving her car. Each hour she was driving, she used 5/6 gallons of gas. What was
nika2105 [10]

Answer:  8  7/10  hours

whole part = 8

fractional part = 7/10

========================================================

Work Shown:

x = number of hours driving

(5/6)x = total number of gallons of gas used

(5/6)x = 7 & 1/4

(5/6)x = 7 + 1/4

(5/6)x = 28/4 + 1/4

(5/6)x = 29/4

x = (29/4)*(6/5)

x = (29*6)/(4*5)

x = 174/20

x = 87/10

x = (80+7)/10

x = 80/10 + 7/10

x = 8 + 7/10

x = 8 & 7/10

This is the same as writing 8  7/10

Amy drove 8 full hours, plus an additional 7/10 of an hour.

That mixed number converts to the decimal value 8.7

What is the leading coefficient of the polynomial x^5-198x+5x^12+4-2x^6 and explain why please
forsale [732]

The given expression is

x^5-198x+5x^{12}+4-2x^6

And we can also write it as

5x^{12}-2x^6+x^5 -198x+4

Leading coefficient is the number or the constant that is with the term with the degree. And here degree is 12, and the constant or the number that is with the term is 5 .

So the leading coefficient is 5 here.
