Can a triangle have side measurements of 1, 4 and 5? Why or why not
Vladimir79 [104]

Answer:

A triangle cannot have side measurements of 1, 4 and 5.

As the sum of two sides i.e. '1+4' of a triangle is not greater than the measure of the third side i.e. '5'.

Step-by-step explanation:

The Triangle Inequality Theorem states that the sum of any two sides of a triangle must be greater than the measure of the third side.

For example, a triangle ΔABC must follow the three conditions which are as follows:

  • A + B > C
  • B + C > A
  • A + C > B

For example, a triangle ΔABC with side lengths:

A = 1

B = 4

C = 5

  • A + B > C    →   1 + 4 > 5      (FALSE)
  • B + C > A    →   4 + 5 > 1      (TRUE)
  • A + C > B    →    1 + 5 > 4     (TRUE)

As the condition i.e. A + B > C    →   1 + 4 > 5  is not satisfied, as 1 + 4 > 5 is False.

Therefore, a triangle cannot have side measurements of 1, 4 and 5.

nexus9112 [7]

Answer:

Child ticket

Step-by-step explanation:

Cost per senior citizen = $10.50

Cost per adult = $15.75

Cost per child = $8.25

Since the cost of the 2 additional ticket is $16.50

Then the only ticket of which two can be purchased with that amount is :

$16.50 / 2

= $8.25

Cost of children ticket.

A square has a perimeter of 38 inches we want to know the length of each side? Chose the best model for this problem. (Side leng
MakcuM [25]

Answer:

perimeter above side length four times

Step-by-step explanation:

we know that

The perimeter of a square is equal to

P=4b

where

b is the length side of the square

Solve the formula by b

That means----> isolate the variable b

Divide by 4 both sides

b=\frac{P}{4}

we have

P=38\ in

substitute

b=\frac{38}{4}=9.5\ in

Rewrite the expression  b=\frac{P}{4}

\frac{P}{b}=4

so

perimeter above side length four times

Two people meet for the first time. What is the probability that they both have the same birthday?
Alenkinab [10]
<span>The first person can have any birthday. That gives him 365 possible birthdays out of 365 days, so the probability of the first person having the "right" birthday is 365/365, or 100%.The chance that the second person has the same birthday is 1/365. To find the probability that both people have this birthday, we have to multiply their separate probabilities. (365/365) * (1/365) = 1/365, or about 0.27%.</span>
