Answer:

the water level decreases by 5 feet per hour

Step-by-step explanation:

firstly the bar is going downwards, hence ,making a loss, decrease etc

so 1st and 3rd are out

initially we had 30ft of water

after

1 hr = 25 ft

- 5 ft decreased

2hrs = 20 ft

- 5 ft decreased again from the previous time checked

3hrs = 15 ft

- 5 ft decreased 1 hr ago

hence the water level decreases by 5 feet per hour

Choose the equation below that represents the line that passes through the point (7, -2) and has a slope of -3

Ray Of Light [21]

Answer:

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

Here m = - 3 and (a, b) = (7, - 2 ), thus

y - (- 2) = - 3(x - 7) , that is

y + 2 = - 3(x - 7) → B

I don't understand rational and irrational numbers

PSYCHO15rus [73]

A rational number is a number which can be expressed as a fraction whose numerator and denominator are both integers and whose denominator is not equal to zero. Rational numbers include all integers, fractions, mixed numbers, and some decimal numbers.

Note : All terminating and repeating decimal numbers are rational numbers because those numbers can be expressed as a fraction. On the other hand, a non repeating number and non terminating decimal, like square root of 2, is an irrational number.

$\dfrac{7}{16} \ as \ a \ decimal = 0.4375$
