Answer:
length = 115 cm
width = 108 cm
Step-by-step explanation:
The perimeter of a rectangular swimming pool is 446 centimeters
LEt L be the length of the pool
The width of the pool is 7 centimeters less than the length of the pool.
width = length - 7
W= L-7
Given perimeter = 446
Perimeter of rectangle = 2(length)+2(width)
446 = 2(L) + 2(W) we know W = L-7
446 = 2(L) + 2(L-7)
446 = 2L + 2L - 14
Add 14 on both sides
460 = 4L
divide by 4 on both sides
L= 115
Length L= 115
Width W = L - 7 = 115 - 7= 108
Answer:
6%
Step-by-step explanation:
6 divided by 100 is 0.06.
then you multiply 0.06 by 135 and that is 8.1
then add 8.1 to 135 and you get 143.1 or 143.10
Answer:
Answer:
44 = 12 + M
Step-by-step explanation:
Start with your final amount that everything else is going to equal
44 =
Then, add the $12 that is already saved to the other side\
44 = 12
But, that equation is not true yet, so we have to add the amount of money that she still needs to save
44 = 12 + M
That equation shows that the money she has saved ($12), plus the amount she still has to save will equal the amount she needs.
Total number of marbles = 10
Number of red marbles = 4
Number of blue marbles = 6
Probability = 
The probability that the first marble is blue = 
The probability that the first marble is red = 
; 9 because 1 marble has already been taken out.
