Answer:
49 units
Step-by-step explanation:
Given the triangles are similar then the ratios of corresponding sides are equal, that is
= 
, substitute values
= 
( cross- multiply )
22BC = 484 ( divide both sides by 22 )
BC = 22
------------------------------------------------
Similarly
= , substitute values
= ( cross- multiply )
22AC = 352 ( divide both sides by 22 )
AC = 16
Thus perimeter of Δ ABC is
perimeter = AB + BC + AC = 11 + 22 + 16 = 49 units
Answer:
She walked neighbor's dog 4 times.
Step-by-step explanation:
It is given that:
Peri earned $27 for walking the dogs 3 times.
Unit rate = 
Unit rate = $9 per dog
Now,
Peri worked at the same rate and earned $36.
Unit rate = 
d= 36/9
d = 4
Therefore,
She walked neighbor's dog 4 times.
C=2pir
A=pir^2
45=pir^2
divide both sides by pi (aprox pi=3.141592)
14.32394785=r^2
sqrt both sides
3.784699176=r
sub
C=2pir
C=(2)(pi)(3.784699176)
aprox pi=3.141592
C=23.779961311m
Naturally, any integer
larger than 127 will return
, and of course
, so we restrict the possible solutions to
.
Now,
is the same as saying there exists some integer
such that
We have
which means that any
that satisfies the modular equivalence must be a divisor of 120, of which there are 16:
.
In the cases where the modulus is smaller than the remainder 7, we can see that the equivalence still holds. For instance,
(If we're allowing
, then I see no reason we shouldn't also allow 2, 3, 4, 5, 6.)
