Answer:
D. 15G > 9
Step-by-step explanation:
Given: G = 3/5
Here we have to check each options and find which is true.
Let's start from A.
G - 1 > 2/5
G > 2/5 + 1
G > 7/5 is not true.
B. -10G > 6
Dividing both sides by -10 , we get
G < -6/10
G < -3/5 Is not true.
C. 1 2/5 + G > 3
Now convert 1 2/5 to improper fraction.
1 2/5 = 7/5
7/5 + G > 3
G > 3 - 7/5
G > (15 - 7)/5
G > 8/5 is not rule.
D. 15G > 9
Dividing both sides by 15, we get
G > 9/15
Now we have to simplify 9/15
G > 3/5 which is true.
Answer: D. 15G > 9
Thank you.
Answer:
26
Step-by-step explanation:
here,
the lower angle when sumed,
it is like: 154+a=180 (let angle be a) being supplementary angle sum is 180
so value of a becomes 26
then,
the above angle x is corresponding to angle a (a=x)
So value x is 26
B. 1/30
Explanation: First you find the probability of picking a yellow marble, 1/6. Then you multiply the probability of picking a blue marble, 1/5 since there are now only five marbles total. Then multiply those to see what the final probability is, 1/6*1/5=1/30.
Answer:
-7 4/5 or -7.8
Step-by-step explanation:
Product means multiplication
( - 13/8 )( 24/5)
= (-13 · 24)/(8 · 5) negative · positive = negative
= - 312/40
= -7 32/ 40 = -7 4/5 or 7.8
Answer:
0.8989
Step-by-step explanation:
Using the Newton's Raphson approximation formula.
Xn+1 = Xn - f(Xn)/f'(Xn)
Given f(x) = x³-2x+2
f'(x) = 3x²-2
If the initial value X1 = 2
X2 = X1 - f(X1)/f'(X1)
X2 = 2 - f(2)/f'(2)
f(2) = 2³-2(2)+2
f(2) = 8-4+2
f(2) = 6
f'(2) = 3(2)²-2
f'(2) = 10
X2 = 2- 6/10
X2 = 14/10
X2 = 1.4
X3 = X2 - f(X2)/f'(X2)
X3 = 1.4 - f(1.4)/f'(1.4)
f(1.4) = 1.4³-2(1.4)+2
f(1.4) = 2.744-2.8+2
f(1.4) = 1.944
f'(1.4) = 3(1.4)²-2
f'(1.4) = 3.880
X3 = 1.4- 1.944/3.880
X3 = 1.4 - 0.5010
X3 = 0.8989
Hence the value of X3 is 0.8989
