Answer:

10\sqrt 2 iN and 10\sqrt 2 jN

Step-by-step explanation:

We are given that

Force =F=20 N

\theta=\frac{\pi}{4}

We have to find the horizontal and vertical component of the force.

Horizontal component of the force =F_x=Fcos\theta i

Horizontal component of the force=F_x=20cos\frac{\pi}{4}i=10\sqrt 2 iN

Vertical component of the force,F_y=Fsin\theta j

Vertical component of the force,F_y=20sin\frac{\pi}{4}j=10\sqrt 2 jN

Force,F=F_x+F_y

F=10\sqrt 2i N+10\sqrt 2j N

I'm a sample bag of m&amp;m's there are 5 brown, 6 yellow, 4 blue, 3 green, and 2 orange. What is the probability of getting 3 y
Vsevolod [243]
There are a total of 5+6+4+3+2=20 M&Ms in the bag.  Since there are 6 yellow M&Ms in the bag, there's a 6/20 probability that the first M&M will be yellow.  Then, there are 5 more yellow M&Ms and 19 more total M&Ms in the bag, so there is a 5/19 chance the next M&M will be yellow.  Finally, there are 4 more yellow M&Ms in the bag and 18 total M&Ms, so there is a 4/18 chance the last M&M will be yellow.

Multiplying these together, we have:

(6*5*4)/(20*19*18)

This simplifies to:

1/57

Therefore, there is a 1/57 probability that all M&Ms will be yellow.

You have in your cash register a 10 dollar bill, 3 five dollar bills, 8 one dollar bills, and 12 quarters, 5 dimes and 10 nickel
nydimaria [60]
First, see how much money you have:

10 + 3(5) + 8(1) + 12(0.25) + 5(0.1) + 10(0.05) =

10 + 15 + 8 + 3 + 0.5 + 0.5 =

37

You need to deposit $7 into the safe, since 37 - 7 = 30.

1 - Qual a solução da equação 3x – 4 = 14? * 1 ponto a) 10 b) 7 c) 6 d) 15 2 - A idade de um pai é igual ao triplo da idade do f
topjm [15]

Responda:

1.) 6;

2.) d) O pai tem 36 anos e o filho tem 12 anos.

Explicação passo a passo:

1.)

Dada a equação: 3x - 4 = 14

3x = 14 + 4

3x = 18

Divida os dois lados por 3

x = 6

2) Dado que ;

Idade do pai = 3 vezes a idade do filho

Idade do pai + idade do filho = 48

Deixe a idade do pai = f; idade da criança = c

Matematicamente ;

f = 3c - - - (1)

f + c = 48 - - - - (2)

Substitua f = 3c em (2)

3c + c = 48

4c = 48

c = 48/4

c = 12

Substitua c = 12 em (2)

f + 12 = 48

f = 48 - 12

f = 36

Portanto ;

Idade do pai = 36 Idade da criança = 12
