nydimaria [60]

Answer:

Slope of the line = 2

Step-by-step explanation:

Slope of a line through two points lying on the line (x_1,y_1) and (x_2,y_2) is given by,

Slope = \frac{y_2-y_1}{x_2-x_1}

From the figure attached,

Given line is passing through two points (0, 1) and (1, 3).

Therefore, slope of the line will be,

Slope = \frac{3-1}{1-0}

          = 2

A person of height 1.6m up to the eye level is standing at a point 2m away from the bank of the river and found an angle of elev
natima [27]

Step-by-step explanation:

tan30° = Height of person / (Distance away from river bank + river's width) = 1/√3.

Therefore 1.6m / (2m + x) = 1/√3

By cross multiplication, 1.6√3 = 2 + x.

Hence, x ≈ 0.77m.

A pineapple is 7 times as heavy as an orange. the pineapple also weighs 870 grams more than the orange. what is the total weight
san4es73 [151]
Let's translate each sentence into "Math".

Pineapple = p

Orange = x

is means equal

 

Pineapple is 7 times as heavy as an orange:  p = 7x

Pineapple weighs 870 grams more than orange. p = 870 + x

 

Substitute  p = 7x  into the second equation:

7x = 870 + x

Subtract  x from both sides

6x = 870

divide by 6

x = 145

 

The orange weighs 145 grams.

The pineapple weights 7 times the orange = 7(145) = 1015 grams.

Answer:

  • 90

Step-by-step explanation:

<u>Factorize both numbers:</u>

  • 900 = 2*2*3*3*5*5
  • 270 = 2*3*3*3*5

<u>Common factors are:</u>

  • 2*3*3*5

<u>So HCF is:</u>

  • HCF(900, 270) = 2*3*3*5 = 90
