Rewrite this single inequality as two inequalities with AND connector. -6 < x < 12 x > -6 and x < 12 x > 12 and x > -6 x < -6 and x > 12
Answer:
The single inequality -6 < x < 12, can be written as two inequalities thus
x > -6 and x < 12
Step-by-step explanation:
For the single inequality -6 < x < 12,
To write the single inequality as two inequalities, first we will separate it into two as
-6 < x and x < 12
-6 is less than x means x is greater than -6, Hence, -6 < x can be written as
x > -6.
∴-6 < x and x < 12 becomes
x > -6 and x < 12
Hence, the single inequality -6 < x < 12, can be written as two inequalities thus
x > -6 and x < 12
Therefore, the correct option is the first one
x > -6 and x < 12

27.4 m/s
40.2 m/s
17.8 m/s
30.3 m/s
30.3 m/s is the correct answer.

A number more than 12
#1. N+12
#2. 12N
#3. 12+N
#4. 12-N
Answer:
#3: 12 + N
Step-by-step explanation:
Adding a number n to 12 results in "a number more than 12."
Thus, the correct answer is #3.

Step-by-step explanation:
A certain county has a population of 34,237 people. The county hospital is interested in estimating the number of people in the county with blood-type A−. To do this, they test blood samples from 245 patients. Out of this group, 12 have blood-type A−. Use this sample to estimate the number of people in the county with blood-type A−.
Answer:
About 1677 people in the county will have blood-type A−.
Step-by-step explanation:
From the question, 12 out of 245 patients have blood-type A−.
To estimate the number of people in the county which has a population of 34,237 people with blood-type A−, we will assume that for every 245 people out of the 34,237 people, 12 of them have blood-type A−.
Let the number of people with blood-type A− in the county be x.
Now,
If 12 people out of 245 people have blood-type A−
Then, x people out of 34237 people will have blood-type A−
245 × x = 34237 × 12
245x = 410844
x = 410844/245
x = 1676.9
x ≅ 1677
Hence, about 1677 people in the county will have blood-type A−.

PLEASE MARK AS BRAINLEST Rectangle ABCD is graphed in the coordinate plane. The following are the vertices of the rectangle: A(-4, -2) B(-2, -2) C(-2, 7) and D(-4, 7).What is the area of rectangle ABCD?
A(-4,-2) B(-2,-2) C(-2, 7) D(-4, 7)
|AB| = √((-2-(-4))^2 + (-2 - (-2))
= √((2)^2 + 0^2) √4
= 2 units
|BC| = √((-2 - (-2))^2 + (7 - (-2))^2
= √5^2 = √25
= 5units.
Let |AB| = The length of the rectangle.
|BC| = The Width of the rectangle.
Hence Area = |AB| × |BC|
Area = 2 × 5 = 10 square units.

Step-by-step explanation:
Lenny makes $55,000 and is getting a $2,500 raise per year. Karl makes $62000, with a $2,000 raise per year. Which inequality shows how many years, y, will it take for Lenny to earn more than or the same salary as Karl. 55000x + 2500 ≤ 62000x + 2000 55000 + 2500x < 62000 + 2000x 55000 + 2500x ≤ 62000 + 2000x 55000 + 2500x ≥ 62000 + 2000x
Answer:
[tex]55000 + 2500x \geq 62000 + 2000x[/tex]
Step-by-step explanation:
Given
Lenny:
Base Earnings = $55000
Raise = 2500 yearly
Karl:
Base Earnings = $62000
Raise = 2000 yearly
Required
Determine the inequality that takes years for Lenny to earn more or exact as Karl
Let y represent years:
Earnings = Base Earnings + Raise * Years
First, we need to determine Lenny's earning:
[tex]Lenny: 55000 + 2500 * x[/tex]
[tex]Lenny: 55000 + 2500x[/tex]
Next, we determine Karl's earning
[tex]Karl: 62000 + 2000 * x[/tex]
[tex]Karl: 62000 + 2000x[/tex]
To determine the required inequality, we have:
[tex]Lenny \geq Karl[/tex]
This gives:
[tex]55000 + 2500x \geq 62000 + 2000x[/tex]
