The answer is $320.
In order to solve this, you can start off by turning this word problem into an expression.
$70x → $70 per hour (x represents the amount of hours)
+40 → plus $40 for the call
Substitute the x for 4 and solve the equation.
70x+40
70(4)+40
280+40
320
The plumber charges $320 for 4 hours of work.
2/14, 4/28, 5 /35, you must divide 2÷2/14/2 = 1/7
and of this form you must divide all the other fractions
Step-by-step explanation:
1 x 1 + 20 =21
2×2+20=24
3×3+20=29
only 5 terms less than 50
Answer:
The fourth pair of statement is true.
9∈A, and 9∈B.
Step-by-step explanation:
Given that,
U={x| x is real number}
A={x| x∈ U and x+2>10}
B={x| x∈ U and 2x>10}
If 5∈ A, Then it will be satisfies x+2>10 , but 5+2<10.
Similarly, If 5∈ B, Then it will be satisfies 2x>10 , but 2.5=10.
So, 5∉A, and 5∉B.
If 6∈ A, Then it will be satisfies x+2>10 , but 6+2<10.
Similarly, If 6∈ B, Then it will be satisfies 2x>10 , and 2.6=12>10.
So, 6∉A, and 6∈B.
If 8∈ A, Then it will be satisfies x+2>10 , but 8+2=10.
Similarly, If 8∈ B, Then it will be satisfies 2x>10. 2.8=16>10.
So, 8∉A, and 8∈B.
If 9∈ A, Then it will be satisfies x+2>10 , but 9+2=11>10.
Similarly, If 9∈ B, Then it will be satisfies 2x>10. 2.9=18>10.
So, 9∈A, and 9∈B.
Yield is given by:
current yield=(annual cash flow)/(market price)
annual cashflow(coupon)= 2.9/100×4750=137.75
market price of the bond= $3940
thus the yield will be given by:
137.75/3940
=0.03496
