The ratio of the sides of a triangle is 2:4:9. If the perimeter is 165 inches, what is the length of the longest side?

Answers

Answer:

99inches

Step-by-step explanation:

The ratio of the sides of a triangle =2:4:9.

perimeter = 165 inches,

Total ratio= 2+4+9=15

perimeter = 165

Divide the perimeter by total ratio

165/15=11

Each of the sides

= (2×11) =22

(4×11) =44

(9×11)=99

the length of the longest side= 99inches

Is 3(5x - 4) = 15x - 12 a one solution , no solution or infinite solutions

Answers

Answer:

Infinite Solutions

Step-by-step explanation:

3(5x - 4) needs to be simplified

So we multiply 5x by 3

So 3 x 5x = 15x

Then we multiply -4 by 3

3 x -4 = - 12

Put those together we get 15x - 12

The same equation as the one on the right side

So since 15x - 12 = 15x - 12, the x variable can be any number

Studies show that people who live in very cold climates have a 30% chance of getting influenza and a 15% chance of getting appendicitis during the winter. What is the probability a person has both diagnoses, rounded to the nearest percent?

Answers

Answer: The probability a person has both diagnoses = 4.5%

Step-by-step explanation:

Given: Chances of getting influenza = 30% = 0.30

Chances of getting appendicitis  = 15% = 0.15

Since both the events are independent , so the probability a person has both diagnoses will be

P(influenza and appendicitis) =P(influenza) x P(appendicitis)

[tex]=0.30\times0.15\\\\=0.045\\\\=4.5\%[/tex]

Hence, the probability a person has both diagnoses = 4.5%

A ABC is isosceles. Find AC.
Please help): I’m not good at geometry

Answers

Answer:

x = 5

Step-by-step explanation:

As it is an isosceles triangle so two sides BA and BC are equal. So,

BA = BC

3x + 3 = 2x + 8

3x - 2x = 8 - 3

x = 5

Therefore AC = 5

In a pair of complementary angles, the measure of the larger angle is twice that of the smaller
angle. What is the measure of the larger angle?
A 30°
B 60°
C 90°
D 120°

Answers

Answer:

D. 120°

Step-by-step explanation:

Complementary angles have a sum of 180 and since its twice the measure of the smaller one so the smaller one would have to be 60 in order for the bigger one to be 120 because you then add your two angles and it should make 180

Answer:

Step-by-step explanation:

Supplementary angles sum to 90. We are told the larger angle is twice the smaller.

L=2S, S=L/2

S+L=90, using S=L/2 we have

L/2+L=90

(3L)/2=90

3L=180

L=60

find the zeros of p(x)= (x-3)(x+3)(2x+1) HELP PLEAEE

Answers

Answer:

3, -3, -1/2

Step-by-step explanation:

There is no need to distribute, just set each parenthesis to equal to zero.

p(x)= (x-3)(x+3)(2x+1)

         X-3=0                     x+3=0                      2X+1=0

           +3  +3                     -3  -3                           -1  -1

             X=3                        X=-3                          2x=-1

                                                                                x=-1/2

So your answers are 3, -3, -1/2

Think About the Process A jar contains only​ pennies, nickels,​ dimes, and quarters. There are 17 pennies, ​12 dimes, and 26 quarters. The rest of the coins are nickels. There are 66 coins in all. How many of the coins are not​ nickels? If n represents the number of nickels in the​ jar, what equation could you use to find​ n?
_____ of the coins are not nickels.

Answers

Answer:

Number of coins that are not nickels = 55 coins

66 = 55 + n

number of nickels in the​ jar = 11

Step-by-step explanation:

Pennies = 17

Dimes = 12

Quarters = 26

Nickels = n

Total coins = 66

How many of the coins are not​ nickels?

= Pennies + Dimes + Quarters

= 17 + 12 + 26

= 55 coins

Number of coins that are not nickels = 55 coins

what equation could you use to find​ n?

Total coins = Pennies + Dimes + Quarters + nickels

66 = 17 + 12 + 26 + n

66 = 55 + n

n = 66 - 55

n = 11

number of nickels in the​ jar = 11
