Answer:
Let x and y be the two numbers. Then
yx=57 and x−y=20
Cross multiplying the proportion
5x=7y or y=75x
So, x−y=20
x−75x=20⇒77x−5x=72x=20
⇒x=2140=70
y=75x=75×70=50
So smaller number is 50.
Check :yx=5070=57 and 70−50=20
Answer:

Step-by-step explanation:
Let be
and
, we plot each curve with the help of graphic tool. In this case, we use Desmos and outcome is presented in the image attached below. Mathematically speaking, a solution to the system of equation exists when
. Graphically speaking, it means that a solution exists when both curves pass through each other.
According to the graphic tool, we conclude that the only solution to the system of equations is
.
Answer:
0.6 probability.
Step-by-step explanation:
Probability of an equally likely situation is measured by # of successes/total # of possibilities.
Thus, there are 3 different values of success(2,3,4)
On the other hand, there are 5 possible different values on the list as per the question(0,1,2,3,4).
Therefore, our probability is equal to 3/5 = 0.60 = 60%
total surface area Stot = 688 mm2
lateral surface area Slat = 324 mm2
top surface area Stop = 182 mm2
bottom surface area Sbot = 182 mm2
10x=20 would be the equation
