Ralph chase invested $85000 at an interest of 10% and $70000 at an interest of 8%
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
An independent variable is a variable that does not depends on other variable while a dependent variable is a variable that depends on other variable.
Let a represent the amount invested at interest of 10% and b represent the amount invested at 8%, hence:
a + b = 155000 (1)
Also:
0.1a + 0.08b = 14100 (2)
From both equations:
a = 85000, b = 70000

Answer:
The infant should be given 700 mg of Claforan every 8 hours.
Step-by-step explanation:
This question involves proportional measures, and asks how many mg of Claforan the infant should be given every 8 hours.
For each kg, the infant should be given 50 mg of Clarofan. The infant weighs 14 kg, so he should be given 14*50 = 700 mg of Claforan every 8 hours.
Answer:
The sector given in the figure is a semi-circle because the degree measure of the chord is 180 degrees.
Area of semicircle = 0.5π
= 0.5π×4.5 = 6.75 sq. inches
