Answer:
4.8
Step-by-step explanation:
1% of 40 is 0.4.
So, just multiply 0.4 by 12 to get 4.8
The class 4S because you divide each number by its mean mark and standard division and 4S is the highest.
A=Pe^(rt)
P = 800g
t = 8 years
A = 450g
r = This is what we will try and find to start with
450=800e^(r*8)
After running the math through a calculator, we end with r = -0.07192
Now we just re-input this information into our equation: A=800e^(-0.07192*16)
A=800e^(1.15072)
Now we will re-write the equation using the negative exponent rule:
A = 800 1/e^1.15072
Combine right side:
A = 800/e^1.15072
Then do the math:
A = 253.12709836......
That will give us A = 253 (rounded to the whole number)
I hope this helps! :)
Answer:
2.3 hours because 18/60=.3 and add the 2 hours
Applying the midsegment theorem, the <u>value of x = 5</u>
<em><u>Recall:</u></em>
- The midsegment theorem of a triangle states that the length of the mid-segment (DE) which is parallel to the third side (AC), is half the length of the third side AC of triangle BAC.
<em><u>Thus:</u></em>
DE = 1/2(AC)
2x - 3 = 1/2(x + 9)
2(2x - 3) = x + 9
4x - 6 = x + 9
4x - x = 6 + 9
3x = 15
x = 5
Therefore, applying the midsegment theorem, the <u>value of x = 5</u>
