Answer:
$7 for the first question
$6.50 for the last one
Answer:
(x2 , y2) = (22,50)
Step-by-step explanation:
Given:
m1 : m2 = 1:4
(x1 , y1) = (7 , 5)
(X ,Y) = (10 ,14)
Find:
(x2 , y2)
Computation:
X = (m1x2 + m2x1) / (m1+m2)
10 = [(1)(x2) + (4)(7)]/(1+4)
10 = [x2 + 28]/5
22 = x2
Y = (m1y2 + m2y1) / (m1+m2)
14 = [(1)(y2) + (4)(5)]/(1+4)
14 = [y2 + 20]/5
70 = y2 + 20
50 = y2
(x2 , y2) = (22,50)
Answer:
D. 
Step-by-step explanation:
Given the inequality 
simply the expression operating the common terms (the terms are common when have the same variables and exponents).
In our occasion the common terms are 
and 
and 3 and 7. So operate this two term for simply in one.
Now substract -10 in both sides of the inequality and get the result:
In this question the main trick lies in the fact that Umesh is getting paid at the rate of 75 cents per kilometer. It has to be converted to dollars for getting to the correct answer. Now let us get down to the problem in hand
75 cents = 0.75 dollars
Then
For 1 kilometer of travel Umesh gets paid = 0.75 dollars
So
For 120 kilometers of travel in a day, Umesh will get paid = 120 * 0.75 dollars
= 90 dollars
From the above deduction we can easily conclude that the travel allowance for Umesh for the day will be $90. I hope this has helped you.
