Vesna [10]

Answer: the third one down

26 miles times 5,280 feet

The base of an isosceles triangle is 2 cm. The perimeter of the triangle is 10 cm.
cluponka [151]

Answer and Step-by-step explanation:

Greetings!

Let's~solve~your~question!

To~find~the~length~of~equal~sides~of~an~isosceles~triangle,~we~use~the~following\\formula.

\boxed{~P=2a+b~}

Now,~solving~for~``a":

P=\frac{P}{2} -\frac{b}{2}

=\frac{10}{2}-\frac{2}{2}

=5-1

=4

Thus,~each~equal~sides~of~an~isosceles~triangle~is~4cm.

Hope~my~answer~helps~and~have~a~blessed~day~ahead!

Answer:

P = 25 + (15)n

Total amount paid by David = $100

Step-by-step explanation:

Given:

Fixed cost of renting chain saw =  $25

Variable cost of renting chain saw =  $15 per hour

Time taken = 5 hour

Find;

Total amount paid by David

Computation:

Assume;

Total amount paid by David = P

Time taken = n

So,

P = 25 + (15)n

P = 25 + (15)(5)

P = 25 + 75

P = 100

Total amount paid by David = $100
