Answer:
Perimeter of a square that measure 5.35 on one side is, 21.4 cm
Step-by-step explanation:
Perimeter of a square is the total length of the boundary of a square.
It is given by:
......[1] where
P represents the perimeter of square,
a represents the side of square.
Given: a = 5.35 cm
Substitute this value in [1] we get;
P = 4(5.35) = 21.4 cm
therefore, the perimeter of a square is, 21.4 cm
Answer:
Step-by-step explanation:
There are 3 blue, 5 red and the total of 8 marbles.
<u>Two different colored marbles are:</u>
- blue, then red or red, then blue
<u>Find the probability of each case:</u>
- P(b, r) = 3/8*5/7 = 15/56
- P(r, b) = 5/8*3/7 = 15/56
<u>Required probability is:</u>
- P(different color) = 15/56*2 = 15/28
2 -> z
5 -> 15
We can see from 5 changing to 15, that multiplying 5 by 3 gives you 15, so multiplying 2 by 3 will give you z.
2 x 3 = 6
A. 6
The answer is 19y – 9.
First, distribute the -3 to ( -4y + 3 ). So:
= ( 12y – 9 ) + 7y
Then, combine like terms. In this case, the like terms are 12y and 7y. So:
= 12y – 9 + 7y
= 19y – 9
