10
Because if you do 5•2 you get 10
More in depth explanation:
Though there are 25 possible configurations the question asks for two different toppings together. It also asks for unique combinations. So AB and BA are the same combination in this context. The only unique possibilities are
AB
AC
AD
AE
BC
BD
BE
CD
CE
DE
It is easy to simplify this into 5•2 for this situation. And if the question asked for three toppings you would do 5•3.
However if the question asked for the configurations for two toppings then you would do 5•5 and if it asked for the configurations of 3 toppings you would do 5•5•5
Length= 2*width
area=l*w=2*width*width=2*width^2
area+160=(2*width+1)*(width+1)
A+160=2w^2+2w+w+1
A+160=2w^2+3w+1
putting value of a
2w^2+160=2w^2+3w+1
160=3w+1
w=53m
l=106m
Answer:
57:43
Step-by-step explanation:
1000 babies - 430 baby boys = 570 baby girls
570 girls to 430 boys
570:430
simplify
57:43
The answer is y-x because there are y seats and x people leave and the key word is leave. When there is words like leave or less those give you hints that mean you are subtracting.
Answer is
C. it's one half the area of rectangle of length 4 units and 3 units
because
Area of rectangle = 4 x 3 = 12
Area of triangle = 1/2(4)(3) = 6
so Area of triangle is one half the area of rectangle of 4 and 3 units
