Answer:
= 9
Step-by-step explanation:
The given parameters are;
The point of intersection of the perpendicular bisectors of the sides , , and intersect (meet) at point G
Let D represent the point of intersection of the perpendicular bisector from G to , we have for ΔBGD and ΔCGD;
≅ by reflexive property
∠GDB = ∠GDC = 90° given that is the perpendicular bisector of
Similarly, ≅ , also given that is the perpendicular bisector of
Therefore;
ΔBGD ≅ ΔCGD by Side-Angle-Side (SAS) rule of congruency
≅ by Congruent Parts of Congruent Triangles are Congruent, (CPCTC)
= = 9 by definition of congruency
∴ = 9.
Answer:
13 nickels and 8 dimes
Step-by-step explanation:
okay, we know that he has $1.45
we know $1= 100 cents.
so we know he has 145 cents
we know one nickel= $0.05
we know one dime=$0.10
we know he has twice as many minuses 3 nickels compared to dimes.
with this information we can make an equation d=dimes n= nickels
145= (5x(n-3)) + (10xd)
we know whatever we plug in for n, d will be half as much. so plug in even numbers that can easily be decided by 2 for n. then take whatever number you put for n and divide it by 2 to get d. for example, if you put 10 for n you would put 5 for d.
eventually you'll end up with an equation that looks like this
145=(5×(16-3))-(10×8)
meaning you have
16-3= 13 nickels
and. 8 dimes
33.3333333333 that should be the answer
