A rectangular water tank is 90cm wide and 40 cm deep. If it can contain 576 liters of water, what is its length?

1 answer:

6 0

Based on the given values above, in order for us to solve it, we need to make the units uniform first. So since the measurement of a rectangular water tank is in cm, we need to convert liters to centimeters cube. So 1 liter is 1000 cubic centimeter. This makes 576 liters 576,000 cubic centimeter. Now that we have the volume, let us recall the formula. V= lxwxh. Just simply plug in the values.
576,000 cm3 = l * 90cm * 40cm
576,000 = l * 3600cm2 (divide both sides by 3600cm2)
L = 160cm
Hope this answer helps.

Answer:

equation: y = 4x

graph is attached

Step-by-step explanation:

Let y represent the cost of the peaches in dollars. Let x represent their weight in pounds. Then the relation between the two variables is ...

cost = (cost per pound) × (pounds)

y = 4x

This graphs as a line through the origin with a slope of 4. In the attached, the x- and y-axes have different scales so more of the graph can be seen.

The sum of 3 consecutive integers is 27 less than the least of the integers..

zysi [14]

Answer: -13, -15

Step-by-step explanation:

If x is the smallest integer, then:

x + (x + 1) + (x + 2) = x - 27

3x + 3 = x - 27

2x = -30

x = -15

Integers: -15, -14, -13

The graph of which function has an amplitude of 3 and a right phase shift of ?

cricket20 [7]

Answer:

The first one

Step-by-step explanation:

The amplitude is usually the first number (for example, in this equation, the 3). Then you also know that the right or left shift depends on the addition or subtraction sign. Usually, the subtraction sign means to the right and the addition sign means to the left.
