Mathematics

Alexxandr [17]3 years ago
7 0

Answer:

300

Step-by-step explanation:

Sum the parts of the ratio, 3 + 4 = 7 parts

Divide the total by 7 to find the value of one part of the ratio.

700 ÷ 7 = 100 ← value of 1 part of the ratio, thus

3 parts = 3 × 100 = 300 ← number of girls

4 parts = 4 × 100 = 400 ← number of boys

Suppose that you are asked to pick a card from a deck of 52 cards. Once you have selected a card, you place it face down on the
serg [7]

Answer:

Step-by-step explanation:

The second card is influenced by the first only in that you have not replaced the first card. That makes a difference.

1/52 is the probability for the first card.

1/51 is the probability for the second card.

They are independent events. Drawing the 7 of diamonds does not make the chances of drawing the Ace of Spades other than the 7 came first and the probability of getting the Ace is slightly larger.

Samuel takes 5 hours to make a table and a chair. He takes 9 hours to make 3 chairs
nikklg [1K]

Answer:

3 hours

Step-by-step explanation:

t = time to make a table

c = time to make a chair

t + c = 5

t+3c = 9

Subtract the second equation from the first

t+3c = 9

-(t + c = 5)

-----------------------

       2c = 4

Divide by 2

2c/2 = 4/2

c =2

2 hours for the chair

t+c = 5

t+2 = 5

t = 5-2

t = 3hours

How do you add vectors? Add the vector <3,4> to the vector that goes 7 units at an angle of 2π/3.
telo118 [61]

The sum of two vectors is (- 0.5, 10.1)

<u>Explanation:</u>

To add two vectors, add the corresponding components.

Let u =⟨u1,u2⟩ and v =⟨v1,v2⟩ be two vectors.

Then, the sum of u and v is the vector

u +v =⟨u1+v1, u2+v2⟩

(b)

Two vectors = ( 3, 4 )

angle 2π/3 = 120°

In x axis, the vector is = 7 cos 120°

                                    = 7 X -\frac{1}{2} \\\\=- \frac{7}{2}

In y axis, the vector is = 7 sin 120°

                                   = 7 X 0.866

                                   = 6.062

The second vectors are ( -3.5, 6.062)

Sum of two vectors = [( 3 + (-3.5) ), (4 + 6.062)]

                               = (- 0.5, 10.1)
