Henry grabs one shoe at a time at random without replacement from a box of ten shoes in his closet. The box contains 4 brown shoes, 2 black shoes, and 4 sneakers. What is the probability that the first two shoes he chooses will be brown? Round to the nearest percent if necessary.?A) twelve percent

B) thirteen percent

C) sixteen percent

D) eighteen percent

Answer:

Option "A" is the correct answer to the following question.

Step-by-step explanation:

Complementary angles ⇒ If the sum of two angles becomes 90 degrees, we can say that this is a complementary pair of angles.

In the given situation angle ∠RST and ∠TSU are a pair of complementary angles.

∠RST + ∠TSU = 90° (Complementary angles)

So, we say that the option "A" is the correct answer.

Answer:

Option A

Step-by-step explanation: I took the test

96 fluid ounces is lessthan 13 cups.

What is unit conversion?

It is the conversion of one unit to another unit with its standard conversion.

Examples:

1 hour = 60 minutes

1 minute = 60 seconds

1 km = 1000 m

We have,

To compare 96 fluidounces and 13 cups, we need to convert one of the quantities so that they are in the same units.

One cup is equal to 8 fluidounces.

So,

13 cups is equal to:

13 cups x 8 fluid ounces/cup

= 104 fluidounces

Now,

We can compare 96 fluid ounces and 104 fluid ounces.

Since 104 is greater than 96.

Thus,

96 fluid ounces is lessthan 13 cups.

The method to solve an equation is

There are three methods used to solve systems of equations: graphing, substitution, and elimination

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

The three methods used to solve systems of equations: graphing, substitution, and elimination

Solving an equation by Graphing :

Simply graph the provided equations and discover the point(s) where they all cross to solve a system. The coordinate of this point will provide you with the values of the variables you are attempting to solve for. This works well when the equations are already in slope-intercept form.

Solving an equation by Substitution:

Substitution is best used when one of the equations is in terms of one of the variables. Once an expression for the variable has been found, substitute or plug it into the other equation where the original variable was to solve for the next variable's integer value. The final step is to substitute the discovered number value for its corresponding variable in the original equation.

Solving an equation by Elimination:

Elimination is the process of combining the equations to obtain an equation with only one variable. This is only possible if the coefficients of one variable in both equations are diametrically opposed and will cancel each other out when put together.

The next step would be to use the equation we devised to determine the variable's value, and then plug that value back into the original equation to determine the remaining variable.

Hence , There are three methods used to solve systems of equations: graphing, substitution, and elimination
