<h3>You can make a square by two congruent right angles triangle. </h3>
1 dozen of calculators = 12 calculators
Selling calculators at $20 for every 3 calculators is the same as selling calculators at $80 for every 12 calculators, or 1 dozen.
b=number of dozen of calculators bought, or 6
s=number of dozen of calculators sold, or 6
p=amount of profit
65(b)-80(s)=|p|
65(6)-80(6)=|p|
390-480=|p|
-90=|p|
90=p
The profit on six dozen calculators is $90.
Answer:
C=50t+150
Step-by-step explanation:
From the information given, the equation will need to show that the total cost of the electrician services would be equal to 50 that is the hourly rate for the number of hours spent working plus the fixed fee:
Fixed fee=250-(50*2)=250-100=150
According to this, the equation would be:
C=50t+150, where C is the total cost of the electrician's services and t is the number of hours spent working.
Hello :
1 )
<span>number cube : a^3 = a×a×a
for exempl : 4^3 = 4</span>×4×4 = 64
2)
<span>a number that is a cube root is : </span>
![\sqrt[3]{b}](https://tex.z-dn.net/?f=%20%5Csqrt%5B3%5D%7Bb%7D%20)
( a number x : <span> b^3 =x )
</span>for exempel :
![\sqrt[3]{8}](https://tex.z-dn.net/?f=%20%5Csqrt%5B3%5D%7B8%7D%20)
= 2 because : 2^3 =8)
