The quotient of a number and 3 minus two is at least -12.
Step-by-step explanation:
The problem would translate to this:
[tex]\frac{x}{3} -2 \geq -12[/tex]
Then add 2 to both sides.
[tex]\frac{x}{3}\geq -10[/tex]
Then multiply both sides by 3.
[tex]x\geq -30[/tex]
The transformation function rule (x, y) --> (x - 1, y) is an example of which type of transformation?
Answer:
translation
Step-by-step explanation:
because it's only being moved left by one unit

A soccer player practices kicking the ball into the goal from halfway down the soccer field. The time it takes for the ball to get to the goal from the time it is kicked averages about three seconds. The soccer field is 90 meters long. The player wants to know the average velocity of the ball.
Is there enough information to calculate this?
A: No, only average speed can be calculated from the distance of 90 meters and the time of three seconds.
B: No, only average speed can be calculated from the distance of 45 meters and the time of three seconds.
C: Yes, displacement is 45 meters, elapsed time is three seconds, and the direction is toward the goal.
D: Yes, displacement is 90 meters, elapsed time is three seconds, and the direction is toward the goal.
Answer: D
Step-by-step explanation:
the distance is 90m and the time is max 3 to goal so the answer is D

Find the constant of proportionality (unit rate) for each set of values
profit per shirt sold
shirts: 5 10 15
profit: $7.50 $15.00 22.50
Answer: 1.5
Step-by-step explanation:
7.50/5 = 1.5
15/10 = 1.5
22.50/15 = 1.5
Answer:
$1.50
Step-by-step explanation:
To find the unit rate, we can divide the number of shirts to the profit that was made to find the unit cost per shirt.
7.50 / 5 = $1.50
15 / 10 = $1.50
22.50 / 15 = $1.50

2) C ( t ) = 4t =15
A) find C ( 4 ).
B) Find C ( t ) = 23.
9514 1404 393
Answer:
a) 31
b) t = 2
Step-by-step explanation:
Put the given value into the equation and solve for the unknown.
a) C(4) = 4·4 +15
C(4) = 31
__
b) 23 = 4t +15
8 = 4t
2 = t
Multiply (−4)(−2)(−5)
A −40
B -8
C 8
D 40
Answer: A. -40
Step-by-step explanation:
-4 x -2 equals 8, 8 times -5 equals -40
Any negative number times another negative number equal a positive number. That number would be 8, but then you multiply 8 which is a possitive number by -5 which is a negative number you would get a negative number again (-40). Is it a trick question or something?

Answer:
n=0
Step-by-step explanation:
both numbers have the same bases which is 5 so we can say that their exponents are equal to each other:
-2n = -2n-3
now we isolate the n variables to one side:
-2n + 2n = -3
0n = -3
n = 0

Help solve pleo
Answer:T = 0.6
Step-by-step explanation:Simplifying
3t + -5 = 0
Reorder the terms:
-5 + 3t = 0
Solving
-5 + 3t = 0
Solving for variable 't'.
Move all terms containing t to the left, all other terms to the right.
Add '5' to each side of the equation.
-5 + 5 + 3t = 0 + 5
Combine like terms: -5 + 5 = 0
0 + 3t = 0 + 5
3t = 0 + 5
Combine like terms: 0 + 5 = 5
3t = 5
Divide each side by '3'.
t = 1.666666667
Simplifying
t = 1.666666667
Answer:
t = 5/3
t = 1 2/3
Step-by-step explanation:
Hi !
3t - 5 = 0
3t = 0 + 5
3t = 5
t = 5/3
t = 1 2/3
Good luck !

Suppose 27 gallons of water came out of a pipe in 9 minutes.what was the rate in gallons per minute

Step-by-step explanation:
Hope this helps pls leave a heart c:
The exam in a course consists of 25 true/false questions, each worth two points, 35 multiple-choice questions, each worth one point, and 5 fill-in-the-blank questions, each worth three points. The probability that a student answers a true/false question correctly is 0.8, the probability that they answer a multiple-choice question correctly is 0.75, and the probability that they answer a fill-in-the-blank question correctly is 0.65. What is the expected score on the exam? Now consider the case where an incorrect answer on a true/false question results in a penalty of −1 point. 2 What is the resulting expected score?
Answer:
Expected Score (No Negative Marking) = 135 points
Expected Score (with penalty) = 130 points
Step-by-step explanation:
First we find no. of true false answered correctly:
True/False Correct = (Total No. of True/False)(Probability to correctly answer true/false)
True/False Correct = (25)(0.8)
True/False Correct = 20
Now, for points scored from true/false:
True/False Score = (True/False Correct)(Points for 1 True/False)
True/False Score = (20)(2)
True/False Score = 40 points
Now, we find no. of mcqs answered correctly:
MCQs Correct = (Total No. of MCQs)(Probability to correctly answer MCQs)
MCQs Correct = (35)(0.75)
MCQs Correct = 26.25 = 26
Now, for points scored from MCQs:
MCQ Score = (MCQs Correct)(Points for 1 MCQ)
MCQ Score = (26)(1)
MCQ Score = 26 points
Now, we find no. of fill in the blanks answered correctly:
Fill in the blanks Correct = (Total No. of Fill in the blanks)(Probability to correctly answer Fill in the blanks)
Fill in the blanks Correct = (35)(0.65)
True/False Correct = 22.75 = 23
Now, for points scored from true/false:
Fill in the blanks Score = (Fill in the blanks Correct)(Points for 1 Fill in the blanks)
Fill in the blanks Score = (23)(3)
Fill in the blanks Score = 69 points
So, the expected total score will be:
Expected Score = 40 points + 26 points + 69 points
Expected Score = 135 points
IN CASE OF PENALTY:
We know that:
Incorrect True/Flase = Total True/False - Correct True/False = 25 - 20 = 5
Therefore,
Total Penalty = (Incorrect True/False)(Penalty on one)
Total Penalty = (5)(- 1 points)
Total Penalty = - 5 points
Now, expected score will be;
Expected Score (with penalty) = 135 points - 5 points
Expected Score (with penalty) = 130 points

Answer:
D!
Step-by-step explanation:
To find the area, we multiply the length times the width to find the number of squares in each box.
A) 1 square down times 7 squares across is 1 x 7, which is 7.
B) 2 squares down times 6 squares across is 2 x 6= 12.
C) 3 squares down times 5 squares across is 3 x 5 = 15.
D) 4 squares down times 4 squares across = 4 x 4 =16.
16 is the biggest number here, so that is the greatest area!

Set a is integers and B is whole numbers which one is correct...please help
-20 and -7 are in circle A, but outside circle B
0, 9, 81 are in circle B
=====================================================
Explanation:
The set of whole numbers is
{0, 1, 2, 3, 4, ...}
While the set of integers is
{ ..., -3, -2, -1, 0, 1, 2, 3, ... }
The difference is that integers involves negative numbers.
-----------------
The upper left corner is incorrect because the "0" should be in set B since 0 is also a whole number. The lower left corner is also ruled out because of this reason.
The upper right corner (choice H) is incorrect as well because 10 and 46 are whole numbers also, so they belong in set B which is a better description/place for them.
So basically the numbers 0,1,2,3,... go in circle B. The negatives of those values will go in circle A, but outside circle B. Only choice J describes this kind of situation.
