40/16 = 24/x
16*24 = 384
x = 384 / 40
x =9.6
it cast a shadow 9.6 feet long
Answer:
35 quarters
Step-by-step explanation:
This situation has two unknowns - the total number of dimes and the total number of quarters. Because we have two unknowns, we will write a system of equations with two equations using the two unknowns.
is an equation representing the total number of coins
is an equation representing the total value in money based on the number of coin. 0.10 and 0.25 come from the value of a dime and quarter individually.
We write the first equation in terms of q by subtracting it across the equal sign to get 
. We now substitute this for d in the second equation.
After simplifying, we subtract 6 across and divide by the coefficient of q.
We now know of the 60 coins that 35 are quarters. To find the total value of the quarters, we multiply 35 by 0.25 and find 8.75.
Answer:
6/10 ; 3/5 (simplified form)
Step-by-step explanation:
To solve, note the decimal place value. Move the decimal point to the right two place values, and set it over 100
0.6 = 60/100
Simplify the fraction. Divide common factors from the numerator & denominator (20 in this case)
(60/100)/(20/20) = 3/5
3/5 is your answer

Answer:
C. 32
Step-by-step explanation:
There are 16 lines of symmetry passing through the vertex's and another 16 passing through the mid points of the sides
When it doesn’t look like a U anymore and is upside down
Looking at an equation than when x is negative
