Answer:
The original price of the dress before the reduction was 90 pound.
Step-by-step explanation:
This question can be solved using a rule of three. The current price, which is 63 pound, is 100 - 30 = 70% = 0.7.
The original price is x pound, and is 100% = 1. So
x pound - 1
63 pound - 0.7
The original price of the dress before the reduction was 90 pound.
A quadrilateral with only 2 right angles could be a trapezoid so Balavan is wrong. Denna is right because if 3 angles are right angles the the fourth angle must also be a right angle and has to be a square or rectangle.
Explain whether the points (−3,8), (−2,3), (−1,−2), (0,−7), (1,−12), and (2,−17) represent the set of all the solutions for the
Volgvan
Answer:
D
Step-by-step explanation:
We simply put each of the points to test
For a point to be correct, if we substitute the x-coordinate value, we should get the value of the y-coordinate
So let’s proceed
(-3,8)
8 = -5(-3) - 7
8 = 15 -7
8 = 8
(-2,3)
3 = -5(-2) - 7
3 = 10 -7
3 = 3
(-1,-2)
-2 = -5(-1) - 7
-2 = 5-7
-2 = -2
(0,-7)
y = -5x -7
y = -5(0) - 7
y = 0-7 = -7
(1,-12)
y = -5(1) -7
-12 = -5 -7
-12 = -12
(2,-17)
-17 = -5(2) -7
-17 = -10-7
-17 = -17
We can see that all the listed points are on the given line
Although all these points lie on the line, we cannot say they represent the set of all solutions
The set of all solutions can simply be represented by the line of the equation
1 nickel = 5 cents
1 dollar = 20 nickels
You can make 13 dollars plus 16 nickels left over
20 * 13 = 260
then 260 + 16 = 276
we have that
Part c)
the probability is equal to
P=0.14+0.27+0.58
<h2>P=0.99</h2>
because is the sum of
x=1, x=2 and x=3
Part D
the probability is
P=0.01+0.14+0.27
<h2>P=0.42</h2>
because is less than or equal 2
