The number of purple marbles in the bag are; 201 purple marbles
<h3>How to work out fraction of bar model?</h3>
We are told that Two-fifths of the marbles are green, and the rest are purple.
A) The image attached shows the bar model where the shaded parts denote the purple marble while the unshaded parts denote the green marbles.
B) We are told that there are 134 green marbles.
If the total number of marbles are x. Then;
(2/5)x = 134
x = 134 * 5/2
x = 335 marbles
Thus;
Purple Marbles = (3/5) * 335 = 201 purple marbles

Answer:
The integers could be 21 and 22
or -22 and -21
Step-by-step explanation:
If two integers are consecutive, then it means that their difference is just 1
if we have the initial value as x , then the other value could be x-1 or x + 1
let us go with x-1
So the product here is;
x(x-1) = 462
x^2-x = 462
x^2 -x -462 = 0
x^2 -22x + 21x - 462 = 0
x(x-22) + 21(x-22) = 0
(x + 21)(x-22) = 0
x = -21 or x = 22
If x = -21
x -1 = -21-1 = -22
if x = 22
x -1 = 22-1 = 21
Answer: 148
Step-by-step explanation:
Answer:
60
Step-by-step explanation:
perimeter (p) = 8 + 17 + 15 = 40
semi-perimeter (s) = p/2 = 20
Area = square root of s(s-a)(s-b)(s-c) where a,b,c are the sides of the triange by Herons formula.
Therefore, area = 20(20-8)(20-15)(20-17) = square root of 3600 = 60
