First look at the factors of 140
140: 1,2,4,5,7,10,14,20,28,35,70,140
35 + 4= 39
35 x 4= 140
Answers are 35 and 4
Answer:
36.25 is equal to the 45.5% of 79.67
Step-by-step explanation:
To solve this you just have to find the value that represents the 100%.
To do this, you can use the Rule of Three that allows you to solve problems of proportions.
In this case, you know that the 45.5% of the magnitude <em>X </em>is 36.25, now you have to find the value which corresponds to the 100%.
Mathematically it will be:
Then you have to solve the equation to find <em>X</em>:
And finally, the answer is:
If they're asking the distance between the tree and the man's shadow, that would be 12ft and if they're asking the distance between the tree and the actually man, that would be 15ft :).
Answer:
14.44
Step-by-step explanation:
The formula says
A=p(1+r)^t
A 7800
P 3600
R 0.055
T ?
7800=3600(1+0.055)^t
7800/3600=(1.055)^t
Log(7800/3600)= t × log(1.055)
T=log(7800/3600)/log(1.055)
T= 14.44 years
Hi,
The answer would be D. Here's why.
You could just do trial and error or like an equation but to make it simple, use trial and error since it is only small number.
If x was 5 and y was -4, just replace them into the equations...
4x+y=16. if x=5 and y=-4, then the equation would be 4*5 +(-4)=16 then it would be 20-4=16. 16=16. There first equation solved. Now lets do the next one. 2x+3y=-2. If x=5 and y=-4, then the equation would 2*5+3*(-4)=-2. Simplify and you get 10+(-12)= -2. 10-12=-2. -2=-2
This is why the answer is D (5, -4)
Hope this helps!
