Answer: 9x-3x and 5x+x
Step-by-step explanation:
1. Brianna's thinking is incorrect because of course, when x is 0, the expression will equal whatever value isn't an x term. To find equivalent expression, you actually need to find which expressions have the same amount of x terms and the same value.
2. Expressions A and C are equivalent.
3. Expression A can be simplified, as you can do 9x - 3x = 6x, so your final expression would be 6x - 4. Expression C can also be simplified with 5x + x = 6x, which can then also be written as 6x - 4. This means both expressions have the same amount of x terms, and the same value, so they are equivalent.
Answer:
Below
Step-by-step explanation:
Brianna's teacher asks her which of these three expressions are equivalent to each other
Expression A: 9x−3x−4 Expression B: 12x−4 Expression C: 5x+x−4
Brianna says that all three expressions are equivalent because the value of each one is −4 when x=0.
Brianna's thinking is incorrect. Identify the error in Brianna's thinking. Determine which of the three expressions are equivalent. Explain or show your process in determining which expressions are equivalent. Enter your answers and your explanation or process in the space provided.
So let's just simplify A and C. B is already simplified.
9x-3x-4
6x-4
5x+x-4
6x-4
So yes, Brianna is incorrect. She added 3x and 9x, instead of subtracting 3x from 9x. A and C are equivalent, but B is all alone.

Answer:
18 1/12 ft = base length
Step-by-step explanation:
The area of a triangle of base b and height h is A = (1/2)(b)(h).
Since we want the measure of the base we solve this formula for b:
2A = (b)(h)
2A
and then divide both sides to obtain a formula for b: b = -----------
h
Substituting 217 ft^2 for A and 24 ft for h, we get:
b = 2*217 ft^2 / 24 ft = 18.0833.... ft
If the answer must contain a fraction, take the 18 and hold it and convert the remaining 0.08333... to a fraction. One way of doing this is to use a calculator. On my old TI calculator, I would type in 0.0833333333..
and then press the MATH key and then select Option 1: Decimal to fraction.
Doing this yields 1/12. You can check this result by dividing: 1/12 = 0.08333...
Then the final answer, converted from 18.08333... ft, is
18 1/12 ft = base length
Given: circle k(O), diameter US, measure of arc RU=50, measure of arc UT=30
Find: measure of angle RUS and measure of angle UST
Answer:
angle RUS = 65 degrees
angle STU = 90 degrees
Step-by-step explanation:
(a) find angle RUS
Given arc RU = 50 degrees, so angle RSU = 50/2 = 25 degrees
Since US is the diameter,
angle URS is a right-angle.
Consider triangle RUS,
sum of angles of a triangle = 25+90+RUS = 180
solve for
RUS = 180 - 25 - 90 = 65 degrees.
(b) Find STU
All diameters span a right angle at the circumference,
since we're given US is a diameter, this means that
angle STU is a right angle.
The measure of the ∠RUS is 65°, while the measure of ∠UST is 15°.
What is Thales theorem?The angle ABC is a right angle if A, B, and C are different points on a circle where the line AC is a diameter, according to Thales' theorem.
We know that when an angle is made by the diameter of a circle at its circumference, then the measure of that angle is 90°.
In ΔUST,
The angle made by the diameter is ∠UST, therefore, the measure of this angle will be 90°. Since the measure of the arcRU=50°, therefore,
arcRU = ∠ROU = 50°, Also,
[tex]\angle RSU=\dfrac{\angle ROU}2 =\dfrac{50^o}2 = 25^o[/tex]
Now, the sum of the angles of a triangle is 180°.
∠R+∠U+∠S=180°
90°+∠RUS+25°=180°
∠RUS = 65°
In ΔRUS,
The angle made by the diameter is ∠URS, therefore, the measure of this angle will be 90°. Since the measure of the arcUT=30°, therefore,
arcUT = ∠UOT = 30°, Also,
[tex]\angle UST=\dfrac{\angle UOT}2 =\dfrac{30^o}2 = 15^o[/tex]
Thus, the measure of the ∠RUS is 65°, while the measure of ∠UST is 15°.

Answer:

Step-by-step explanation:
Step-by-step explanation:
First, you need to know some terms related to probability. When working with probability, a random action or series of actions is called a trial. An outcome is the result of a trial, and an event is a particular collection of outcomes. Events are usually described using a common characteristic of the outcomes.
Let's apply this language to see how the terms work in practice. Some games require rolling a die with six sides, numbered from 1 to 6. (Dice is the plural of the die.) The chart below illustrates the use of trial, outcome, and event for such a game:
Trial
Outcomes
Examples of Events
Rolling a die
There are 6 possible outcomes:
{1, 2, 3, 4, 5, 6}
Rolling an even number: {2, 4, 6}
Rolling a 3: {3}
Rolling a 1 or a 3: {1, 3}
Rolling a 1 and a 3: { } (Only one number can be rolled, so this outcome is impossible. The event has no outcomes in it.)
Notice that a collection of outcomes is put in braces and separated by commas.
A simple event is an event with only one outcome. Rolling a 1 would be a simple event because there is only one outcome that works—1! Rolling more than a 5 would also be a simple event because the event includes only 6 as a valid outcome. A compound event is an event with more than one outcome. For example, in rolling one six-sided die, rolling an even number could occur with one of three outcomes: 2, 4, and 6.
When you roll a six-sided die many times, you should not expect any outcome to happen more often than another (assuming that it is a fair die). The outcomes in a situation like this are said to be equally likely. It’s very important to recognize when outcomes are equally likely when calculating probability. Since each outcome in the die-rolling trial is equally likely, you would expect to get each outcome of the rolls. That is, you'd expect the rolls to be 1, of the rolls to be 2, of the rolls to be 3, and so on.
A spinner is divided into four equal parts, each colored with a different color as shown below. When this spinner is spun, the arrow points to one of the colors. Are the outcomes equally likely?
A) Yes, they are equally likely.
B) No, they are not equally likely.
Answer:
All the outcomes are equally likely. Each color provides a different outcome, and each color takes up the circle. You would expect the arrow to point to each color of the time.

A block of iron has dimensions of 1 cm x 2 cm x 5 cm and has a
mass of 799
What is its density? (V=lxwxh)
Answer:
79.9 units
Step-by-step explanation:
Hi there,
Before solving this problem, it is important to know the formula:
D = [tex]\frac{m}{v}[/tex].
D = density
m = mass
v = volume
Since we are given the mass and volume, we can simply enter these values into the formula to find the density of the block.
D = [tex]\frac{799}{10}[/tex]
D = 79.9
Therefore, the density of the block of iron is 79.9 units. I wrote units since you did not specify the unit for the mass. Hope this answer and explanation helps.
Cheers.

Answer:
triangle side = 0.54
so both triangle sides = 1.08
and then the sides (1.5 * 3.5) * 2 = 10.5
the last side = 0.9 * 3.5 = 3.15
so add it all 3.15 + 10.5 + 1.08
total area = 14.73 m^2
