Na casa de Isabel, a leitura do hidrômetro, feita no dia 20 de março, indicava 2431 metros cúbicos. Uma nova leitura, feita um mês depois, indicou 2 590 metros cúbicos. Quantos metros cúbicos de água Isabel e seus familiares consumiram nesse período?

Answers

Answer 1

Answer:

159 metros cúbicos

Step-by-step explanation:

Os metros cúbicos de água que Isabel e sua família consumiram durante este período são calculados como:

Nova leitura - primeira leitura

Primeira leitura = 2.431 metros cúbicos

Nova leitura = 2590 metros cúbicos

Conseqüentemente:

2.590 metros cúbicos - 2.431 metros cúbicos

= 159 metros cúbicos

Answer:

A) 6 square meters

Step-by-step explanation:

To find the area of a triangle you must multiple the base and the height, but in this question the base isn't given. Using the Pythagorean theorem to find the base you get 4 as the base. Now you multiply 3 and 4 to get 12 (square area), then divide it by two and get 6 (triangle area)

Steps:

b^2 = 5^2 - 3^2

b^2 = 16

[tex]\sqrt{b} = 4[/tex]

3*4 = 12

12/2 = 6 square meters

find the 50ty term if the nth term is 5n-3

Answers

Answer:

247

Step-by-step explanation:

From the question given above, the following data were obtained:

nth term (Tₙ) = 5n – 3

Number of term (n) = 50

50th term (T₅₀) =?

The 50th term can be obtained as follow:

Tₙ = 5n – 3

T₅₀ = 5(50) – 3

T₅₀ = 250 – 3

T₅₀ = 247

Therefore, the 50th term is 247.

Answer:

A. Rectangle

Step-by-step explanation:

Shown in the attachment are the four points graphed on a coordinate plane.

We can see that the opposite sides are parallel to each other and have the same length.

The answer cannot be B. Square because the side lengths of this quadrilateral are not all equal to each other.

The answer cannot be C. Rhombus because of the same reason as above.

The answer cannot be D. Trapezoid because the bases of the quadrilateral are not of different lengths.

Therefore, the answer must be A. Rectangle since the angles are 90° angles, and the opposite sides are parallel and equal.

Write an equation that relates the number of tennis balls (y), with the number of cans (x). (Do not put spaces between numbers, variables, and operations)

Answers

Answer:

y = 3x

Step-by-step explanation:

Since, line given in the graph passes through origin (0, 0), relation between the number of tennis balls (y) and the number of cans (x) will be proportional.

y ∝ x

y = kx

Here 'k' = proportionality constant

Since the given line is passing through (1, 3),

3 = k(1)

k = 3

Therefore, equation of the line will be,

y = 3x
