For the shower multiply the amount of water per minute by number of minutes:

10.6 x 7 = 74.2 liters.

Calculate volume of the tube and the amount of water in it:

35 x 40 x 120 = 168,000 cubic cm.

Convert to liters:

168,000/ 1000 = 168 liters.

Savings = 168 - 74.2 = 93.8 liters

Step-by-step explanation:

$a + b = 6$

$ab = 1 \times 5 = 5$

$a = 1 \: \: \: \: \: \: \: \: b = 5$

$( {x}^{2} + x) + (5x + 5)$

$x(x + 1) + 5(x + 1)$

$(x + 1)(x + 5)$

Hope this is correct and helpful

vfiekz [6]

Answer:

Step-by-step explanation:

difference of x-coordinates = 4-(-3) = 7

difference of y-coordinates = 0-(-2) = 2

length of MN = √(7²+2²) = √53 ≅ 7.28 units

tanθ = 2/7

θ = arctan(2/7) ≅ 15.9°

1.) In a department store, a $120 belt is marked 25% off.

lawyer [7]

Answer:

$30

$90

Step-by-step explanation:

Given parameters:

Selling price of belt = $120

Percentage discount = 25%

Unknown:

Discount = ?

Sale price of the dress = ?

Solution:

Discount is a reduction in the price of a commodity.

Discount = percentage discount x selling price of belt

Input the parameters and solve;

I. Discount = $\frac{25}{100}$ x 120 = $30

II. Sale price of the dress;

= selling price - discount amount

= $120 - $30

= $90
