Answer:
1.96
Step-by-step explanation:
A farmer sells 9.8 kl of apples and pears
4/5 of this weight is apples, while the rest are pears
Therefore the wight of pears can be calculated as follows
Let x represent the weight of pears
9.8= 4/5×9.8 + x
9.8= 0.8×9.8+x
9.8= 7.84+x
9.8-7.84= x
x= 1.96
Set up a x/100 = (14-48)/48 = -34/48 Multiply the cross 48x = -3400 x = 70.8333 so around -70.83% change
Answer:
<h3>2</h3>
Step-by-step explanation:
Given the expression -3-(-5)
This is also expressed as;
-3(-5)
= -3 + 5 (The product of two negative sign gives a positive sign)
= 5 - 3
= 2
Hence the result of the expression is 2
Answer:
2 years
Step-by-step explanation:
13000 X 0.05 = 650
13000 - 650 = 12350 year 1
12350 X 0.05 =617.5
12350 - 617.5 =11732.5 year 2
Answer:
b = (log(y^45))/log(1/y^9) + (2 i π n)/log(1/y^9) for n element Z
Step-by-step explanation:
Solve for b:
(1/y^9)^b = y^45
Take the logarithm base 1/y^9 of both sides:
Answer: b = (log(y^45))/log(1/y^9) + (2 i π n)/log(1/y^9) for n element Z
