Answer:
A. EDHG is congruent to PRLQ ; the simplified fraction scale of EDHG to this polygon is 1.5
(Multiply the values of the sides by 1.5 and you will see that you will get the same values of the polygon EDHG)
B. cannot be because the angles are the same .
C. cannot be because the corresponding sides are congruent
D. cannot be because the corresponding side are proportional
E. cannot be because corresponding angles are proportional
Answer:
$55
Step-by-step explanation:
Let b represent the original bill. The problem statement tells us ...
20% × (b -6) = 9.80
Dividing by 20% gives ...
b -6 = 49.00
b = 55.00 . . . . . . . add 6
Their bill before the discount was $55.00.
___
<em>Comment on the tip</em>
It is generally considered better form to tip on the basis of the original bill before coupons and discounts.
Answer:
0.15%
Step-by-step explanation:
3 standard deviations encompasses 99.7% of the data symmetrically around the mean with 0.15% on each side that is above and below. so above would be 0.15%
well you have to see how far they have gotten after 4 hours. so 4*40=160 50*4=200. since it was opposite directions you add. so 160+200=360.
Answer:
y=2
-7x-4
three linear equations
c=-4 ;4a+b=1 ; 9=a-b
Step-by-step explanation:
Simply assume a standard parabola equation y=a +bx +c
(here a, b, c are three independent variables)
Three coordinates as shown in graph are (0,4), (4,0) ,(-1,5)
Now put these points in the equation of parabola and get three linear equations.
[1] c=-4
[2] 4a+b=1
[3] 9=a-b
Now substitute value of a from equation 2 into 3 in terms of b
a= 
9=-b
b=-7
a=2
y=2 -7x-4
