Answer:

30/169

Step-by-step explanation:

We need to know how many marbles in the bag

6 red marbles + 2 white marbles + 5 blue marbles = 13 marbles

P (red) = red / total = 6/13

We then put the marble bad so there are still 13 marbles in the bag

P(blue) = blue /total = 5/13

P (red then blue ) = P(red) *P(blue)

                             = 6/13 * 5/13 = 30/169

The perimeter of a rectangular field is 336 m. If the length of the field is 89 m, what is its width?​
exis [7]
The length of the field will be calculated as:
P=2(L+W)
P=376
W=89
thus substituting the values in the equation we get;
376=2(L+89)
376/2=(L+89)
solving for L;
188=L+89
L=188-89
L=99 yards
therefore the length is 99 yards

Hope it helps!

The slant height of a regular square pyramid is longer than its altitude.
andrezito [222]
Always

Because the slant length is the longest length when looking at the Pythagoras theorm

In this case the slant is y, with x and y as the height and base
y²=x^{2}+y^{2}

Hence y the slant is the sum of the height and and base and will always be larger
