Answer:
25
Step-by-step explanation:
First of all let's rearrange the equation for the given line:
4x + 7y + 3 = 0
7y = -4x - 3
y = (-4/7)x - 3/7
Now we know that the gradient of the line is -4/7
The gradients of two perpendicular lines multiply by each other to give -1, ie.
(-4/7)*m = -1
m = -1/(-4/7)
= 7/4, therefor the gradient of the perpendicular line is 7/4
Now we can substitute this and the point (-2, 1) into the equation y - y1 = m(x - x1)
y - 1 = 7/4(x - (-2))
y = 7/4x + 7/2 + 1
y = 7/4x + 9/2
If we look at the given answers then C is correct, since 9/2 = 18/4 and so the equation may also be written as y = 7/4x + 18/4
Answer:
21 inches
Step-by-step explanation:
We can write a ratio to solve
7 inches x inches
------------- = -------------------
1 bracelet 3 bracelets
Using cross products
7*3 = 1x
21 = x
21 inches

Answer:
the amount of ferrous sulphate child will digest = 213.3 mg
Step-by-step explanation:
Given,
Amount of FEOSOL Elixir swallowed by child = 1.6 Fluid ounces
= 1.6 x 29.57 ml
= 47.312 ml
= 0.2133 gram
= 213.3 mg
So, the amount of ferrous sulphate child will digest = 213.3 mg
