Let x be the number of pennies which is also equal to the number of dimes. By this representation, the number of quarters is equal 46 - 2x. The total amount is $4.87 or 487 cents. The equation that best represent the given is,
x + 10x + 25(46 - 2x) = 487
The value of x from the equation is 17. Therefore, there are 17 of both pennies and dimes and 12 quarters.
Answer:
b
Step-by-step explanation:
6^2+8^2=100
sqrt of 100 = 10 so it would form a right triangle
Divide the amount donated by total sales then multiply by 100.
350 / 8750 = 0.04
0.04 x 100 = 4%
Answer:
it is 803.84 centimeters squared
Step-by-step explanation:
area of a circle is r^2* 3.14
=16*16*3.14
=803.84
The answer should be b¹². You add the exponents of each constant. In the case of the simple b the exponent would be one.
