We need to find the probability that a student will winn a gift card of at leat $25.

We use probability formula:

Probability=\frac{\text{Favorable events}}{total\text{ events}}

In this case, the total number of events is: 8

this is because we have 8 possible triangles as the result.

The favorable events are the number of triangle that have a value of at least $25, which are the following:

The only two favorable events are $25 and $50, so

Favorable events = 2

Substituting this into our probability formula:

Probability=\frac{\text{Favorable events}}{total\text{ events}}=\frac{2}{8}

We can simplify this probability as 1/4, or as 0.25

Answer: 2/8=1/4=0.25

How can you find the area of diameter
sveticcg [70]
HEY THERE !!

As we know that the area of a circle (A)= πr^2

But if we know the diameter then the area is (A)= π/4× D^2 { here D is for diameter}

Here diameter is 10.5 inches.

A => π/4 × (10.5)^2
A => π/4 × 110.25
A => π/4 × 27.5625
A => 86.54625 { because the value of π = 3.14}

So the area of the cirsle whose diameter is 10.5 inches is 86.54625 inches square.

HOPE IT HELPED YOU.

How do I fine x in this problem. 4x+3y=12
RSB [31]

Answer:

Answer: It's relatively easy to find x in this problem. 4x+3y=12 means that the expression 3y needs to be 12 too, which gives us 12-6 or 6. That number divided by 4 is 2, so x=2! Congrats, you've found x!

Step-by-step explanation:

One way of solving this problem is to remove the parentheses all together and write the equation as 8x+6y = 54. Subtracting 54 from both sides would give us -8x + 6y = 18. The key point here is that when subtracting a negative number, we have to borrow one from our variable so instead our answer becomes (-8)x-6(y)=-54.
