The lengths of the sides of a triangle are in the ratio 5: 6: 7. describe the length of the longest side if the perimeter is less than 54cm.

length of the longest side is  less than 21

Step-by-step explanation:

5n+6n+7n=18n

18n<54

n<54/18

n<3

7*3=21( longest side. )

Less than 21 cm.

Step-by-step explanation:

Let x represent the multiplier.

We have been given that the lengths of the sides of a triangle are in the ratio 5:6:7. The perimeter of all sides of the triangle would be .

We have been given that the perimeter is less than 54 cm.

We can set this information in an inequality as:

Since the length of longest side is , so:

Therefore, the length of the longest side will be less than 21 cm.

a) 0.25x times 3. (could be wrong on equation.)

b) 2.25 pound of dark chocolate. (can i eat all the chocolate? plz? anyway, again, could be wrong, but i hope im right. all the chocolate together should be 5.25 pounds)

have a good day!

answer: c, the green line

step-by-step explanation:

there is no black line, eliminate b.

simple interest implies periodic payments, but the red line shows no payments, eliminate d.

simple interest has equal payments. if paid say every day, the graph is about a straight line (actually a stairstep).

the yellow line is not straight, eliminate a.

check: the green line is straight, answer is c.

simple interest with positive interest rate gives a straight line sloping up to the right. green line:

g(t) = $100 + ($200-$100) ÷ (20 years) × (t years)

= $100 + (4%/year) × ($100)(t years)

incidentally, the yellow line curving upward represents continuously compounded interest

y = $100 × 2^(t years / (14 assuming the yellow line hits $200 at 14 years. 2^0 is 1, so y(0) = $100; 2^(14/14) is 2, so y(14) = $200.
