4.0081 x 10 to the 4th power. I know because I did this one.
Answer:
She has 11 dimes and 17 nickels
Step-by-step explanation:
dimes --- d
nickels -- n
Equation with number of coins: 

Divide by 5

sub in the other equation:

She has 11 dimes and 17 nickels
check:
total = 11 + 17 = 28 , check!
value: 10(11) = 5(17) = 195 , check!
Answer:
y=12
x=48
Step-by-step explanation:
Relationship shows that
y=1/4x
if we put y=12 and x=48 it holds.
The distance traveled to the top of the escalator to the bottom is 52 ft
Here, we want to calculate the distance a person on the escalator travel from the bottom to the top of the escalator
Firstly, we need a diagrammatic representation to understand this
We can form a right-angled triangle with the information given in the question.
The diagram is shown as below;
From the question, by simply calculating the hypotenuse of the right-angled triangle, we can get the distance traveled from the bottom of the escalator to the top
Let us call this distance d
We can now use the appropriate trigonometric ratio
The trigonometric ratio to use here is the sine since we have the opposite and we want to calculate the hypotenuse
Mathematically;
Answer:
157 - 70x
