Water flows from a tank with a rectangular base measuring 80cm by 70cm into another tank with a squarebase of side 60cm. If the

defon

Answer:

70cm

Step-by-step explanation:

Since, both of the tank posses the same quantity of water then there volume is the same thing

For rectangular base

Volume= (Lenght × breadth × hheight)

If we substitute values

Lenght= 80 cm

Breadth= 70 cm

height= 45 cm

Volume= 80cm × 70cm × 45cm

Volume= 252000cm^3

For square base

Volume= (side)^2 × height

side =60cm.

But volume of square base= volume of

rectangular base

252000cm^3= 60^2 × height

Height= (252000cm^3)/(60^2 )

Height= 70 cm

Hence, the second tank is 70 cm deep

HLEPPPPPP!!!!!

Ksenya-84 [330]

Answer:

Solutions:-5,0,9,6

Not solutions: 12.5,10

Explanation:

The inequality that was given is:

20 > 5 + 3x

First, group similar terms;

20 - 5 < 3x

15 < 3x

x = 5

Thus, the solutions are:-3.5, 5, 4 3/4, -15

The not solutions are:-10 2/3, 129,

Hope this helps! :)

L'età media di Aldo, Bruno, Carlo e Davide è 16 anni. Se non si tiene conto di Davide, l'età media dei tre rimanenti sale a 18.

photoshop1234 [79]

Answer:

Davide's age is 10.

L'età di Davide è 10.

Step-by-step explanation:

The average age of Aldo, Bruno, Carlo and Davide is 16 years.

I am going to say that:

x is Aldo's age.

y is Bruno's age.

z is Carlo's age.

w is Davide's age.

Average of the 4 is 16 years.

This means that:

$16 = \frac{x + y + z + w}{4}$

$x + y + z + w = 64$

If we do not consider Davide, the mean is 18. So

$18 = \frac{x + y + z}{3}$

$x + y + z = 54$

Replacing in the first equation:

$x + y + z + w = 64$

$54 + w = 64$

$w = 10$

Davide's age is 10.

L'età di Davide è 10.

What is an equation of the line that contains the point (3,-1) and is perpendicular to the line whose equation is y=-3x+2

yanalaym [24]

Answer:

Equation of the line: $3y=x+10$

Step-by-step explanation:

If an equation of a line is perpendicular, its gradient will be such that: $m_1 \times m_2 = -1$

Since the gradient /slope of the given equation can be inferred as -3, the gradient of the perpendicular line will be $\frac{1}{3}$ .

Coordinates of a point on the line are (3,-1)

$(y-y_1) = m(x-x_1)\\\\(y-3) = \frac{1}{3} (x+1)\\\\3(y-3) = (x+1)\\3y -9= x+1\\3y = x+1+9\\3y = x+10$
