Choose which expression doesn’t belong? State your reasoning.
Answer:
Step-by-step explanation:
This warm-up prompts students to carefully analyze and compare quadratic expressions. In making comparisons, students need to look for common structure and have a reason to use language precisely (MP7, MP6). The activity also enables the teacher to hear the terminology students know and how they talk about characteristics of the different forms of expressions.
As students discuss in groups, listen for rationales that are based on the structure of the expressions. Select those students or groups to share their thinking during class discussion.
Launch
Arrange students in groups of 2–4. Display the expressions for all to see. Give students 1 minute of quiet think time and then time to share their thinking with their small group. In their small groups, ask each student to share their reasoning about why a particular item does not belong, and together find at least one reason each item doesn't belong.

what is the anser to the equation 2^{2x+2} = 2^{3x}
A) x = 2.5
B) x = 1
C) x = 2
D) x = -2
Answer: C) x = 2
2^{2x + 2} = 2^{3x}
Since both terms (above) have the same base, set the exponents to be equal:
2x + 2 = 3x (Rearrange to solve for x)
x = 2
∴ x = 2

Find c.
Round to the nearest tenth:
2 cm
15°
105
Answer:
0.5cm
Step-by-step explanation:
Using the sine rule
Answer:
c = 0.5 cm
Step-by-step explanation:
Using the Sine rule in the triangle, then
[tex]\frac{c}{sin15}[/tex] = [tex]\frac{2}{sin105}[/tex] ( cross- multiply )
c × sin105° = 2 × sin15° ( divide both sides by sin105°
c = [tex]\frac{2sin15}{sin105}[/tex] ≈ 0.5 cm ( to the nearest tenth )
At a gas station, all chips are marked down 10%. A customer brings a bag of chips with a regular price of $2.19 to the register. After the 7% sales tax on the final price, how much does the customer pay for the bag of chips ?
Answer: $2.11
Step-by-step explanation:
A customer brings a bag of chips with a regular price of $2.19 to the register which is marked down 10% the price to pay will be:
= $2.19 - (10% × $2.19)
= $2.19 - $0.219
= $1.971
After a 7% sales tax on the final price, the amount paid by the customer will be:
= $1.971 + (7% × $1.971)
= $1.971 + $0.13797
= $2.11

Noah says that to find 20% of a number he divides the number by 5. For example, 20% of 60 is 12, because . Does Noah's method always work? Explain why or why not.
Answer:
Yes Noah's method will always work
Step-by-step explanation:
Noah's method states that:
To find 20% of a number he divides the number by 5. For example, 20% of 60 is 12.
Noah's method will always work because:
20% = 20/100
Simplifying 20/100 to the least fraction = 20/100 = 1/5
20% of x = 1/5 × x
= x/5 = x ÷ 5
Applying this to the examples
20% of 60 = 1/5 × 60
= 60/5 = 12.
Therefore, Noah's method will always work.

Mr. Ellis owns a landscaping company. He sends two crews to mow grass. Crew A mows 6 acres in 7.5 hours. Crew B mows 4.5 acres in 6 hours. Which crew is faster?
Hey there!
The answer to your question is Crew A
We can find this by first finding the unit rate, or acres per hour. We can divide the amount of acres by the amount of hours.
Crew A : 6/7.5 = 0.8 acres per hour
Crew B : 4.5/6 = 0.75 acres per hour
With the data above, we can see that Crew A is faster.
Hope it helps and have an amazing day! Remember, You've got this!
Answer:
A crew

Answer:
Step-by-step explanation:
1. Fig.2 is harder to drive on. Because the gravity is pulling you to opposite direction. Thats why there's no such roads on hills, they always go round and round to make the roads easier to drive on.
2. Fig.2 will build up more speed, because gravity will pull unidirectional from you.
3. (Realitiscally) no, DONT TEXT AND DRIVE. Even if you are driving on a flat ground.
4. No, of course not. In situation no.1 and 2, you can drive like that because there is gravitational pull coming from x and y axis. But from situation no.4, the gravitational pull is from y axis only, so it will only pull you down.
The perimeter of a square can be expressed by the function f(s) = 4s, where s is the length of the side in inches.
How do the mathematical domain and reasonable domain compare?
Answer:
Mathematical domain is all numbers, as all numbers can be multiplied by 4. However, this is not reasonable as negative lengths don't exist, so the reasonable domain would be all positive numbers.
