if the sides of a triangle are in the ratio 3:4:5, prove that it is
right-angled triangle​

Answers

Answer 1

Answer:

hope this helps

Step-by-step explanation:

Let a , b , c are three sides of a triangle

a : b : c = 3 : 4 : 5

a = 3x ,

b = 4x ,

c = 5x

a² = 9x²

b² = 16x²,

c² = 25x².

c² = a² + b²

by the pythagorean theorem,

a , b , c forms a right angled Triangle.

Answer 2

Answer:

yes it's a right angle triangle

Step-by-step explanation:

Given the sides are in the ratio 3:4:5.

Let ABC be the given triangle.

Let the sides be 3x,4x and hypotenuse be 5x.

According to Pythagoras theorem,

A box is filled with 9 brown cards, 2 yellow cards, and 3 blue cards. A card is chosen at random from the box. What is the probability that it is a brown or a blue
card?

Answers

Answer:

9 / 14 for a brown , 3 / 14 for a blue

Step-by-step explanation:

1) summarize all cards 9 (brown) + 2 (yellow) + 3 (blue)= 14 cards.

2) probability depends on how many cards of a particular color, how more cards, then more probability.  

3) 9 brown cards, so probability = 9 brown cards to divide all cards 14.

The proportion is given by the equation c = pg where the value of p is

p = 0.75

What is Proportion?

The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.

The proportional equation is given as y ∝ x

And , y = kx where k is the proportionality constant

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Given data ,

Let the proportion be represented as p

Now , the equation will be

Jaiden mixed 6 cups chocolate chips with 8 cups of granola to make trail mix

So , for 6 cups chocolate chips = p x 8 cups of granola

So , the proportion will be

Substituting the values in the equation , we get

6 = p x 8

Divide by 8 on both sides of the equation , we get

p = 6/8

On simplifying the equation , we get

p = 0.75

Therefore , the value of p is 0.75

Hence , the proportion equation is c = 0.75g

Aldo made 12 of 18 baskets during the first half of the basketball game. What is the experimental probability that he will make the next basket?

Answers

Answer:

I think that the answer is 66%

Step-by-step explanation:

12/18

divide both numbers by 6

2/3

turn this fraction into a percentage

66%

The experimental probability that he will make the next basket will be 66.66%.

What is Probability?

The formula to calculate the probability of occurrence of an event 'A' can be written as -  

P(A)  = n(A)/n(S)  

where -

n(A) = Number of outcomes favorable to event A.

n(S) = Total number of outcomes.

Given is Aldo made 12 of 18 baskets during the first half of the basketball game.

If Aldo made 12 of 18 baskets during the first half of the basketball game, then we can write the experimental probability as -

P(E) = 12/18 = 2/3

P(E) = 2/3 x 100 = 66.66%

Hence, the experimental probability that he will make the next basket will be 66.66%.

Triangle inequality

Answers

Answer:

DF

EF

DE

Step-by-step explanation:

First, we need to figure out the third angle.

Angles in a triangle add up to 180, so

180 = 61 + 59 + DEF

DEF = 180 - (61 + 59) = 180 - 120 = 60

In a triangle, the smallest angle is always opposite the shortest side, and the largest angle opposite the longest.

The three angles are 61, 60, and 59.

Since DEF(61) is the largest, DF is the longest.

Next is EDF(60), so EF is the next.

Finally, DFE(59) is the smallest angle, so DE is the shortest.

Colton's mini-van is depreciating at a rate of 5.5% per year. He paid $22,250 for it in 2019. How much will the car be worth in 2025 to nearest cent?

Answers

Answer:

$1584.2

Step-by-step explanation:

Given data

R= 5.5%

T= 2025-- 2019=  6years

P=  $22,25

Let us apply Compound interest formula

A=P(1-r)^r ------------Note negative for  depreciation

A= 2225(1-0.055)^6

A= 2225(0.945)^6

A= 2225*0.712

A=$1584.2

Answers

Answer:

See Explanation

Step-by-step explanation:

The question has missing details; as the radius or an attachment of the hemisphere is not given.

However, I'll solve on a general terms.

The volume of a hemisphere is: [tex]V = \frac{2}{3}\pi r^3[/tex]

Take for instance

[tex]r = 14.9cm[/tex]

The volume becomes:

[tex]V = \frac{2}{3} * 3.142 * 14.9^3[/tex]

[tex]V = \frac{2 * 3.142 * 14.9^3}{3}[/tex]

[tex]V = \frac{20787.151516}{3}[/tex]

[tex]V = 6929.051cm^3[/tex]

So, all you need to do is plug in the value of radius in the formula.
