Do red blood cell have pseuopods
No, red blood cells do not have pseudopods. Pseudopods are temporary cytoplasmic extensions that are used for cell movement and/or capturing prey in certain types of cells, such as amoebas. Red blood cells, also known as erythrocytes, do not have a nucleus or most organelles, including pseudopods. Their main role is to transport oxygen to tissues throughout the body.
Jorelle is planning a 5-day vacation. The trip will cost him $1,300.00 for airfare, food, and itineraries. He plans to stay in a hotel room for $80.00 per night. He only has $950.00 in savings, but he earns $25.00 per hour from his online tutoring services. Create a linear inequality in one variable that would best translate the problem. Determine the minimum number of hours Jorelle must tutor so he can have enough money for the trip.
Let's let the variable "x" represent the number of hours Jorelle must tutor.
The cost of the trip is $1300.00, and he has $950.00 in savings. To figure out how much more money he needs, we subtract his savings from the cost of the trip: $1300.00 - $950.00 = $350.00
Jorelle earns $25.00 per hour tutoring, so the amount of money he earns will be 25x.
To have enough money for the trip, his earnings from tutoring must be greater than or equal to the remaining cost of the trip. So, the inequality can be written as:
25x ≥ 350
This inequality states that Jorelle must tutor for a minimum of (350/25) = 14 hours to have enough money for the trip.

950+25x≤1,300; at most 14 hours
950 plus 25 x less-than-or-equal-to 1,300 ; at most 14 hours
950+25x≤1,700; at most 30 hours
950 plus 25 x less-than-or-equal-to 1,700 ; at most 30 hours
950+25x≥1,700; at least 30 hours
950 plus 25 x greater-than-or-equal-to 1,700 ; at least 30 hours
950+25x≥1,300; at least 14 hours
The correct linear inequality in this case is:
950 + 25x ≥ 1300
This inequality states that the sum of Jorelle's savings ($950) and his earnings from tutoring ($25x) must be greater than or equal to the total cost of the trip ($1300).
To determine the minimum number of hours Jorelle must tutor, we can solve this inequality:
950 + 25x ≥ 1300
Subtracting 950 from both sides:
25x ≥ 350
Dividing both sides by 25:
x ≥ 14
So, Jorelle must tutor for a minimum of 14 hours in order to have enough money for the trip.
Mary Ann solves the inequality −3x≥12. Justify the steps Mary Ann takes to find the solution set
To solve the inequality -3x ≥ 12, Mary Ann needs to isolate the variable "x" to find the solution set. Here are the steps she takes with justifications:
1. She divides both sides of the inequality by -3:
(-3x) / -3 ≥ 12 / -3
Justification: Dividing both sides by a negative number reverses the inequality sign.
2. Simplifying, she gets:
x ≤ -4
Justification: When dividing both sides by a negative number, the inequality sign flips.
Therefore, the solution to the inequality -3x ≥ 12 is x ≤ -4. This means that any value of "x" that is less than or equal to -4 will satisfy the original inequality.
Kirk solves the inequality 5<12y−7. Which statement explains the steps he uses to find the solution set of the inequality
To find the solution set for the inequality 5 < 12y - 7, Kirk follows these steps:
1. Kirk adds 7 to both sides of the inequality:
5 + 7 < 12y - 7 + 7
Justification: By adding 7 to both sides, he isolates the term containing the variable on the right side of the inequality.
2. Simplifying both sides, he gets:
12 < 12y
Justification: By combining like terms, the equation becomes easier to work with.
3. Next, Kirk divides both sides of the inequality by 12:
12 / 12 < 12y / 12
Justification: To isolate the variable "y" on the right side, he divides both sides by the coefficient 12.
4. Simplifying further, he obtains:
1 < y
Justification: Dividing both terms by the same positive number doesn't reverse the inequality.
Therefore, the solution set for the inequality 5 < 12y - 7 is y > 1. This means any value of "y" greater than 1 will satisfy the original inequality.

Kirk adds 7 to both sides of the inequality, then divides both sides of the equivalent inequality by 12 and reverses the inequality symbol to get 1>y.
