Answer:

315 minutes

Step-by-step explanation:

To solve this, we must divide the gallons of the swimming pool by the rate of gallons per minute.

7,000 gallons divided by 22.2 minutes equals 315.3 minutes.

We can round this to 315.

315 minutes is how long it will take to fill the pool.

Find the slope please

Katarina [22]

Answer:

slope is $-\frac{3}{4}$

Step-by-step explanation:

1,-1 -3,2 are two points on the graph

the equation to find slope is $\frac{y_{1}- y_{2} }{x_{1}- x_{2} }$

so $\frac{2--1}{-3-1} = -\frac{3}{4}$

or you can count how many places it changed in the equation $\frac{rise}{run}$

Find the height of the triangle by applying formulas for the area of a triangle and

lina2011 [118]

Answer:

Step-by-step explanation:

a= 12 mm ; b = 16 mm ; c = 18 mm

s = (a + b+c)/2

$=\dfrac{12 + 16 + 8}{2}\\\\= \dfrac{36}{2}\\\\= 18\\\\$

s -a = 18 - 12 = 6 mm

s -b = 18 - 16 = 2 mm

s -c = 18 - 8 = 10 mm

$area = \sqrt{s(s -a)(s-b)(s-c)}$

$= \sqrt{18*6*2*10}\\\\= \sqrt{2160 }\\\\=46.47\\\\=46 \ mm^{2}\\$

$\dfrac{1}{2}* \ base * \ height = 46\\\\\dfrac{1}{2}*16* \ height = 46\\\\height = \dfrac{46*2}{16}\\\\$

= 5.75

Height = 5.8 mm

In a group of 60 workers they get paid an average of 80$ a day per person.

hichkok12 [17]

Answer:

48 workers earn $75 a day.

Step-by-step explanation:

Let x people earn 75 a day then 60-x earn 100 dollars a day.

Average is $80 a day so total paid out to the 60 workers

= 60*80 = $4800.

So 75x + 100(60-x) = 4800

75x + 6000 - 100x = 4800

6000 - 4800 = 100x - 75x

1200 = 25x

x = 48.
