Answer:
x × 0.1 < y × 0.2
x = 100, y = 10
Step-by-step explanation:
10% of a really large number can be bigger than 20% of a small number. 10% of 100 is 10. 20% of 10 is 2. 10 is bigger than 2 so Sergi's claim is false.

A phone company has two long distance
calling plans. The first plan is $25 per month
for unlimited long distance calling. The second
plan is $10 per month plus $0.05 per minute
of long distance calling. After how many
minutes of long distance calls will it be cheaper
for a customer to purchase the first plan?
Answer:
After 300 minutes of long distance calls it will be cheaper for a customer to purchase the first plan.
Step-by-step explanation:
With the information provided, you have to find the amount of minutes of long distance calls where it will be cheaper for the customer to purchase the first plan by stating that the price of the second plan which is calculated by adding up the fixed fee plus the result of multiplying the price per minute for the number of minutes is higher than the price of the first plan, which could be express as:
10+0.05x>25, where:
x is the number of minutes
Now, you can solve for x:
0.05x>25-10
0.05x>15
x>15/0.05
x>300
According to this, the answer is that after 300 minutes of long distance calls it will be cheaper for a customer to purchase the first plan.

Which number sentence shows one way to find the sum of 4 and 5?
Answer:
x-5=4 or simply 4+5
Step-by-step explanation:
Im not sure if this is how you mean they both have a way of showing the sum of 4 and 5.
Answer:
4 + 4 + 1 = 9
Step-by-step explanation:
to solve this, we first find the sum of 4 and 5, which is 9.
Then, we can observe our answer choices, and see that option 4.) would be correct, because the sum still is equal to nine, even though the numbers are different from the original problem.

A news reporter states that a study shows that 63% of people prefer vanilla ice cream to chocolate ice cream, plus or minus 2% points. The margin of error in this example is _____.
Answer: 21
Why: 21/2321
Using the concept of a confidence interval, it is that the margin of error in this example is of 2%.
------------------------
A confidence interval for a percentage is written in the following format:
[tex]P \pm M[/tex]
That is, the percentage is of P, plus of minus M points, in which M is the margin of error.
------------------------
In this question, the percentage is 63% plus or minus 2%, thus, the margin of error is of 2%.A similar problem is given at https://brainly.com/question/21496409

Blake needs at least $81 to buy a new phone. He saves $9 every week. Which inequality best represents this
scenario.
Answer:
9x ≥ 81
Step-by-step explanation:
Given
Total = $81 (atleast)
Required
Represent as an inequality
Let the number of weeks he x
If he saves $9 in a week, then he will save $9x in weeks
From the question we understand that he needs at least $81
At least, in inequality means ≥
So, the inequality is:.

Answer:
y² + 2 x y
Step-by-step explanation:
Given polynomials
x² + 3x y -y² and x² + 5xy
The subtract x² + 3x y -y² from x² + 5xy
x² + 5xy - ( x² + 3x y -y²)
⇒ x² + 5xy -x² - 3xy +y²

According to the triangle inequity if 20 and 25 are the lengths of two sides of a triangle then an inequality that represents all possible lengths for the third side is_____
A. 0
B. 0
C. 5_
D. 5
Answer and explanation:
The inequality theorem states that the sum of the length of two sides of a triangle is greater than the third side of a triangle.
Also the difference of two sides of a triangle is less than the third side
If we apply this theorem here,
Then we say the third side x<20+25 and x>25-20
Therefore x<45 but >5
5<x<45
Possible sides of x include: 6,7,8,9,10,11,12,13,14,15,16,17,18...not equal to 45 or more than
A circle has a radius of length 8 . A central angle, theta , cuts off an arc of 210. what is the arc length
Answer:

Mr. Martinez sells vehicles to 20% of the people that come to the dealership. If 65 people came to the dealership last month, how many vehicles did he sell?
Answer:
13 vehicles
Step-by-step explanation:
Just solve 20% of 65. "Of" means to multiply, and 20% is just 0.2
So, you would do:
0.2 × 65 = 13 vehicles

please help me asap
Answer:
Step-by-step explanation:
From the picture attached,
∠4 = 45°, ∠5 = 135° and ∠10 = ∠11
Part A
∠1 = ∠4 = 45° [Vertically opposite angles]
∠1 + ∠3 = 180° [Linear pair of angles]
∠3 = 180° - ∠1
= 180° - 45°
= 135°
∠2 = ∠3 = 135° [Vertically opposite angles]
∠8 = ∠5 = 135° [Vertically opposite angles]
∠5 + ∠6 = 180° [Linear pair of angles]
∠6 = 180° - 135°
∠6 = 45°
∠7 = ∠6 = 45° [Vertically opposite angles]
By triangle sum theorem,
m∠4 + m∠7 + m∠10 = 180°
45° + 45° + m∠10 = 180°
m∠10 = 180° - 90°
m∠10 = 90°
m∠10 = m∠12 = 90° [Vertically opposite angles]
m∠10 = m∠11 = 90° [Given]
Part B
1). ∠1 ≅ ∠4 [Vertically opposite angles]
2). ∠7 + ∠5 = 180° [Linear pair]
3). ∠9 + ∠10 = 180° [Linear pair]

How many sheets of plywood would you need for two gables in a home if the gables are 42’ wide by 5’ high?
Answer:
7 sheets
Step-by-step explanation:
Dimension of gabble = 42' by 5'
Dimension of standard plywood sheet : 4' by 8'
Area that will be covered by gabble :
Length * width :
42 * 5 = 210 in²
Area covered by 1 plywood sheet :
4 * 8 = 32 in²
Number of plywood sheets required :
Area of gabble / Area of 1 plywood sheet
210 in² / 32 in²
= 6.5625
This means the number of plywood sheets that will be required is 7

A bag contains counters that are red, black , or green . 1/3 of the counters are red 1/6 of the counters are black There are 15 green counters in the bag. How many black counters are in the bag ?
i’ll give brainliest please help
Answer:
5 black counters
Step-by-step explanation:
1/3 to sixths would equal two sixths. The problem already told us three of the siths, meaning the 15 are the other three sixths. Since 3/6 are half of the bag, then multiply 15 by two. Since there are 30 in all, and the bags are in thirds, you devide by three. Since 10 is the 1/3, you divide by 2 (10 by 2) since you multiply 1/3 to get the equivalant of 2/6. There are 5 black ones.
You could've also had done 30 divided by 6 to get 5 which is still the 1/6 of the bag.
