Answer:
I only know the first question, If you leave that money for 1 year it would equal $480 basically, $300 x 1.6 = $480.
Step-by-step explanation:
See this is what you should do ask
When a line is perpendicular to another line, the gradient becomes the “negative reciprocal” which basically means flip the gradient and change the sign. In this instance the negative reciprocal of 5x has to be -1/5 as it has been flipped and made negative. At this point the answer can only be B or C.
After this you can use the point given to work out the y-intercept:
y-y1 = m(x-x1)
y-3 = -1/5(x+10)
y-3 = -1/5x - 2
y = -1/5x -1
And there’s your answer: C
To find this answer multiply the cost of the ice cream by 18%/100, or .18
$154 x .18 = $27.72
Answer:
No, it is not a magic square.
Step-by-step explanation:
A magic square is when whatever way you add it from, it is always the same answer (the magic sum). As you can clearly tell, it doesn't add up to the same number.
