Answer:

10/20 or 1/2

Step-by-step explanation:

There are 10 pink balls out of 20. (add all the numbers together)

So that means there is a 10/20 chance to get a pink ball.

Answer:

[tex]\frac{1}{2}[/tex]

Step-by-step explanation:

So, the probability is the number of favored outcomes/ number of possible outcomes.

In this case, the favored outcomes is pink, which is 10.

The number of possible outcomes is 2+1+10+2+5 = 20

This gives us 10/20, which is 1/2 when simplified

If the runner travels 8 miles in 2 hours then the speed of the runner is 4 miles per hour.

The runner traveled 8 miles in 2 hours.

To find the runner's speed, we can use the formula:

Speed (in miles per hour) = Distance / Time

In this case, the distance is 8 miles and the time is 2 hours:

Speed = 8 miles / 2 hours

= 4 miles per hour

So, the runner's speed is 4 miles per hour which means that the runner covers a distance of 4 miles for every hour they run.

Answer:

  less

Step-by-step explanation:

We can answer the question about relative sizes of a square and a circle by finding the area of each.

__

The area of the square is ...

  A = s²

  A = (2 in)² = 4 in²

The area of the circle is ...

  A = πr²

  A = π(1.2 in)² = 1.44π in² ≈ 4.524 in²

The area of the square is less than the area of the circle.

_____

Additional comment

The area of a circle is π/4 times the area of the square in which it is inscribed. If the diameter of the circle is 1.2 times the side length of the square, its area ratio to the square will be (1.2²)(π/4) = 0.36π ≈ 1.13. That is, the circle is larger and the square is smaller.

Answer:

area= 22cm× 14cm= 308cm²

L=√81

L=9ft

By using the first two points on the graph, we conclude that exponential equation is:

y = 200*(0.4)^t

We assume that the equation is an exponential decay of the form:

y = A*(r)^t

When t = 0 we have:

y = A

On the graph we can see that the initial value is 200, then A = 200, so we have:

y = 200*(r)^t

By looking at the graph we can see that:

80 = 200*(r)^1    (this is the second point graphed).

Solving for r we get:

80 = 200*(r)

80/200 = r = 0.4

Then the exponential equation is:

y = 200*(0.4)^t

Answer:

Only one triangle is possible.

Step-by-step explanation:

Triangle inequality says that if sum of any two sides of the traingle is greater than the third side, then the triangle is possible.

Here,

,

Therefore, a triangle is possible with the given measurements,

Let us assume there is another triangle with same measurement with same measurements 7 cm, 6 cm, and 9 cm.,

By SSS congruency criteria both the triangles will be congruent.

Thus, all triangles with same measurement will be congruent to each other.

Hence, only one triangle is possible.

Answer: the greatist value is 30,000

Step-by-step explanation:

The exponent rules are given below.

We are given that;

To state exponent rules

Now,

Exponent rules are the laws or principles that govern the operations on numbers or variables with exponents. An exponent is a number or a variable that tells how many times to use the base in a multiplication.

There are different exponent rules for different situations, such as multiplying, dividing, raising to another power, or having a negative or fractional exponent. Here is a table of some common exponent rules with examples:

| Rule | Example |

[tex]| x^1 = x | 6^1 = 6 |[/tex]

[tex]| x^0 = 1 | 7^0 = 1 |[/tex]

[tex]| x^-1 = 1/x | 4^-1 = 1/4 |[/tex]

[tex]| x^m * x^n = x^(m+n) | 2^3 * 2^4 = 2^(3+4) = 2^7 |[/tex]

[tex]| x^m / x^n = x^(m-n) | 2^5 / 2^3 = 2^(5-3) = 2^2 |[/tex]

[tex]| (x^m)^n = x^(mn) | (2^3)^2 = 2^(3*2) = 2^6 |[/tex]

[tex]| (xy)^n = x^n * y^n | (3*4)^2 = 3^2 * 4^2 |[/tex]

[tex]| (x/y)^n = x^n / y^n | (4/2)^3 = 4^3 / 2^3 |[/tex]

[tex]| x^(m/n) = n-th root of x^m | 2^(6/3) = cube root of 2^6 |[/tex]

We can use these rules to simplify expressions with exponents or to perform calculations with them.
