Atotal of $4.80 consisting of dimes and quarters was collected from a soft drink vending machine. if there's one more quarter than there are dimes, find the number of dimes and the number of quarters.
a. 18 dimes; 12 quarters
b. 12 dimes; 13 quarters
c. 13 dimes; 14 quarters
d. 14 dimes; 15 quarters

Step-by-step explanation:

multipy .10 by 18 and you get 1.80$ then 12 quarters is 3.00 so 1.80+ 3.00= 4.80

make sure you have version 2.50

try looking in the very back of the book : )

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
