Jasmine reduced the size of a triangle to a height of 4 in. What is the new width if it was originally 12 in wide and 16 in tall

cupoosta [38]

Answer:

The new width is 3 in.

Step-by-step explanation:

We can use the ratio of w/h, the origal width and height should have the same ratio as the new width and height.

12 = x

16 4

Then solve for x:

x = 4 (12/16)

x = 3

To check:

12/16 = 3/4

3/4 = 3/4

Y = 1.6x + 48

jekas [21]

Answer:

7.5

Step-by-step explanation:

y=1.6x + 48

so you put 60 where y is

60=1.6x + 48

then you subtract 48 from both sides

60-48=1.6x + 48-48

12=1.6x

then you divide 1.6 by both sides

12/1.6=1.6/1.6x

so your answer will be

7.5=x

and also if you put 7.5 where x is in the equation you will get 60 just so you know that.

A pair of fair dice is cast. what is the probabiliy that the sum of the numbers falling uppermost is 9, given that at least one

WITCHER [35]

If a pair of fair dice is cast, the probability that the sum of the numbers falling uppermost is 9, given that at least one of the numbers falling uppermost is a 3 is given by:

$\frac{P(sum\, of\, 9\, \cup\,3)}{P(3)}$

The number of outcomes of sum of 9 where at last one is 3 is (3, 6) and (6, 3) = 2.

The number of outcomes of last one of the numbers falling uppermost is a 3 is (3, 1), (3, 2), (3, 3), (3, 4), (3, 5), (3, 6), (1, 3), (2, 3), (4, 3), (5, 3) and (6, 3) = 11.

Therefore, the probabiliy that the sum of the numbers falling uppermost is 9, given that at least one of the numbers falling uppermost is a 3 is 2 / 11.
