670 If a die is rolled 3 times, what is the total number of possible outcomes?

Triss [41]

There is to say, for each first roll, we start out with six possibilities; for each of these, there are six possibilities for the second roll; finally, for each second roll, there are six possibilities for the third. So, 6 cubed. So, 216 is our denominator, i.e., the number of all possible outcomes.

Answer: 216

What is the area of a triangle whose side is 17 meters long

Lunna [17]

Answer:

125.141

Step-by-step explanation:

Assuming that this is an equilateral triangle, I am going to divide this triangle in half to get a right triangle.

17 is our hypotenuse

17/2 = 8.5, this is one of our legs

The other leg is our height, which we will find.

We use Pythagoras Theorem to find the height/leg: $a^{2} +b^{2} =c^{2}$

$17^{2} -8.5^{2} = 216.75$

$\sqrt{216.75}$ = 14.72243186

Now, we use another formula to find the area of the triangle: $\frac{Base*Height}{2}$

14.72243186 × 17 = 250.2813416

250.2813416 ÷ 2 = 125.1406708

jesse has 18 cups of flour to make 78 pancakes . how many pancakes can jesse make with 12 cups of flour

Lynna [10]

78÷18=4.3333333
so it's 4.33333 many pancakes with one cup
so then you multiply 4.33333... by 12 which equals 52

So you can make 52 pancakes with 12 cups of flour

Plz, answer! 34 + 2 ⋅ 5 =

8_murik_8 [283]

$3^{4}$ + 2 × 5

To evaluate apply the rules of PEMDAS (Parentheses, Exponent, Multiplication, Division, Addition, Subtraction)

Parentheses

There are none for this steps so go on to the next step

Exponent:

$3^{4}$

so...

81 + 2 × 5

Multiplication:

81 + 2 × 5

2 × 5

so...

81 + 10

No division in this equation so skip this step and go to the next one

Addition:

81 + 10

Hope this helped!
