Answers:
a) 75ml/hr
b) 0ml left
Explanation:
a) 750ml - 450ml = 300ml (This is how much we know the bag drained within 4hrs)
300ml/4=75ml
so now we know the rate of drain is 75ml/hr
b) since rate is 75ml/hr:
75*6=450
450-450=0
Hence there will be no fluid left for the patient.
Answer:
$41000
Step-by-step explanation:
If her salary was $1,000 more than the previous year and she save $4,200, $4,200 was 10% of her salary. So we should create an equation. (x being her salary from the previous year)
0.1(x+1000)=4200 (divide 4200 by .01)
x+100=42000
42000-1000= 41000

Answer:
0.7
Step-by-step explanation:
The shorter side of the triangle is 18 cm and each of the longer sides are 54 cm
<u>Solution:</u>
Given that triangle has perimeter of 126 cm
Let the length of the shorter side of the triangle be "a"
The 2 longer sides are 3 times as long as the shortest side
So length of 2 longer sides = 3(length of the shorter side)
length of 2 longer sides = 3a
<em><u>The perimeter of triangle is given as:</u></em>
perimeter of triangle = length of the shorter side + length of 2 longer sides
perimeter of triangle = a + 3a + 3a
126 = a + 3a + 3a
7a = 126
a = 18
So length of shorter side = 18 cm
length of 2 longer sides are each = 3a = 3(18) = 54 cm
Thus, the shorter side of the triangle is 18 cm and each of the longer sides is 54 cm
