Which comparison is NOT correct?
2 > -3
-7 < -5
-9 < 1
0 < -4
2 > -3 (2 is greater than -3, this is true)
-7 < -5 (-7 is less than -5, this is true because -7 is more negative than -5)
-9 < 1 (-9 is less than 1, this is true)
0 < -4 (0 is less than -4, this is false because 0 is greater than -4)
Among the comparisons given, "0 < -4" is incorrect.
The student is asking which comparison is not correct. After evaluating each comparison, it becomes clear that 0 < -4 is not correct because 0 is not less than -4; in fact, 0 is greater. Other comparisons such as 2 > -3, -7 < -5, and -9 < 1 are all correct, as in each case, the number on the left side of the inequality is indeed larger (or smaller, for negative numbers) than the number on the right side as the symbol indicates.
To understand why 0 < -4 is incorrect, consider the number line where any number to the right is greater than the number to the left. Zero (0) lies to the right of any negative number, including -4, which means it is greater, not less.
Each person in the vale family drinks 481/2 ounces of water a day how much water will each person drink in 7 days
Each person in the Vale family will drink a total of 339.5 ounces of water over the course of 7 days.
The student is asking how much water in ounces each person in the Vale family will drink over the span of 7 days if each person drinks 48.5 ounces of water daily.
To find the total amount of water consumed by one person in 7 days, we multiply the daily intake by the number of days:
48.5 ounces/day imes 7 days = 339.5 ounces
So, each person will drink a total of 339.5 ounces of water in 7 days.
Given: Ray BC bisects angle ABD.
Which pair of angles must be congruent?
A) ∠ABD & ∠EBD
B) ∠ABC & ∠DBE
C) ∠ABC & ∠DBC
D) ∠ABD & ∠CBDill mark brainliest if correct and give 50 pts.
Congruent is the same size and same shape. When a ray bisects an angle, the two newly created angles will be congruent, since the ray went right in the middle of the first angle (so in this case, ABC and DBC will be congruent)
Answer: C) ∠ABC & ∠DBC
Step-by-step explanation:
When a ray bisect an angle , then it divided the original angle into two congruent angles.
We are given that Ray BC bisects angle ABD.
Then, Ray BC divides ∠ABD into two congruent angles.
From the picture, The angle formed by it : ∠ABC & ∠DBC
So ∠ABC & ∠DBC must be congruent.
Hence, the pair of angles must be congruent : ∠ABC & ∠DBC

Is (1, 2) a solution of the system y > 2x and x+y<3?
Select one:
a. Yes, because (1, 2) is a solution to both inequalities.
b. Yes, because (1, 2) is the point of intersection of the two boundary lines of
this system.
c. No, because (1, 2) is a solution to only one of these inequalities.
d. No, because (1, 2) is not a solution to either inequality.
Answer:
d
Step-by-step explanation:
To determine if (1, 2) is a solution to the system
Substitute x = 1, y = 2 into the inequalities and check their validity.
y > 2x → 2 > 2 ← incorrect statement
x + y < 3
1 + 2 < 3 → 3 < 3 ← incorrect statement
(1, 2) is not a solution to either inequality → d

tents hold 2, 3, 5, 6, or 12 people. how many combinations of tents are possible to sleep 32 all tents are fully occupied and exactly one 12 person tent is used.
there would be 12 combinations
Answer:
12
Step-by-step explanation:
We are given that tent hold 2,3,5,6 or 12 people.
We have to find the combinations of tents are possible to sleep 32 all tents are fully occupied and exactly one 12 person tent is used.
If one 12 person tents is used then remaining people=32-12=20
Therefore, 20 people that must be in other tents.
To place 20 persons in combination of 2,3,5 and 6.
20=5+5+5+5
20=5+5+5+2+3
20=6+6+6+2
20=2(10)=2+2+....+2(10 times)
20=5+5+2(5)(5 times add 2)
20=6+6+2(4) (4 times add 2)
20=3+3+3+3+3+3+2
20=3+3+3+3+3+5
20=3+2+6+5+2+2
20=3+3+3+3+6+2
20=3+3+5+5+2+2
20=6+6+3+5
Hence, there are 12 possible combination of tents to sleep 32 all tents are fully occupied and exactly one 12 person tents is used.
15. Divide the polynomial x^3 + x^2 - 2x + 3 by (x - 1).
Answer:
x² + 2x + [3\x - 1]
Step-by-step explanation:
Since the divisor is in the form of x - c, use what is called Synthetic Division. Remember, in this formula, -c gives you the OPPOSITE terms of what they really are, so do not forget it. Anyway, here is how it is done:
1| 1 1 -2 3
↓ 1 2 0
------------------
1 2 0 3 → x² + 2x + [3\x - 1]
You start by placing the c in the top left corner, then list all the coefficients of your dividend [x² + 5x - 36]. You bring down the original term closest to c then begin your multiplication. Now depending on what symbol your result is tells you whether the next step is to subtract or add, then you continue this process starting with multiplication all the way up until you reach the end. Now, when the last term is 0, that means you have no remainder, which in this case is a 3, so what you is set the divisor underneath the remainder of 3. Finally, your quotient is one degree less than your dividend, so that 1 in your quotient can be an x², 2 becomes 2x, and the remainder of 3 is set over the divisor, giving you the other factor of x² + 2x + [3\x - 1].

Simplify the rational expression x^2-4/x^2+5x+6. State any restrictions on the variable.
Answer:
The correct answer is option B.
Step-by-step explanation:
The given rational expression is:
[tex]\frac{x^2-4}{x^2+5x+6}[/tex]
Factor the numerator and the denominator:
[tex]\frac{x^2-2^2}{x^2+2x+3x+6}[/tex]
Factor the numerator using difference of two squares and the denominator using factorization by grouping.
[tex]\frac{(x-2)}{x(x+2)+3(x+2)}[/tex]
[tex]\frac{(x-2)(x+2)}{(x+2)(x+3)}[/tex]
This function is defined if and only if the denominator is not zero.
That is: (x+3)(x+2)≠0.
x≠-2,x≠-3
We simplify now to obtain:
[tex]\frac{x-2}{x+3}[/tex]
The correct choice is the second option.
Option B is correct.

At a local company, the ages of all new employees hired during the last 10 years are normally distributed. The mean age is 31 years old, with a standard deviation of 10 years. If you were to take a sampling of 10 employees, what is the probability your mean age will be at least 28? Round to the nearest percent.
Answer:
The probability your mean age will be at least 28 is 83%
Step-by-step explanation:
Let X denote the ages of all new employees hired during the last 10 years , then X is normally distributed with;
a mean of 31
a standard deviation of 10.
The sample size obtained is 10 employees. This implies that the sampling distribution of the sample mean will be normal with;
a mean of 31
a standard deviation of [tex]\sqrt{10}[/tex]
The sample mean is a statistic and thus has its own distribution. Its mean is equal to the population mean, 31 and its standard deviation is equal to [tex]\frac{sigma}{\sqrt{n} }[/tex]
where sigma is the population standard deviation, 10 and n the sample size which in this case is 10. [tex]\frac{10}{\sqrt{10} }=\sqrt{10}[/tex]
We are required to find the probability that this sample mean age will be at least 28;
P(sample mean ≥ 28)
Since we know the distribution of the sample mean we simply standardize it to obtain the z-score associated with it;
P(sample mean ≥ 28)
= [tex]P(Z\geq \frac{28-31}{\sqrt{10} } )=P(Z\geq -0.9487)[/tex]
=0.8286
As a percentage this is equivalent to, 83%

An elevator in a hotel moves at 20 feet per second. leaving from the ground floor, its height in feet after t seconds is given by the formula h(t)=20t. A bolt comes loose in the elevator shaft above, and its height in feet after falling for t seconds is given by h(t)=-16t^2+200. At what time and at what height does the bolt hit the elevator?
Answer:
After 7.5 seconds and a height of 0
Step-by-step explanation:
The time taken for the bolt to hit the elevator is 3 seconds, at a height of 60 feet.
Given that the elevator height is h(t)=20t while the bolt height is given by h(t)=-16t² + 200.
At the point when the bolt hit the elevator, they would be at the same height, hence:
-16t² + 200 = 20t
16t² + 20t - 200 = 0
t = -4.2 or t = 3
Therefore the time taken for the bolt to hit the elevator is 3 seconds, the height is:
h(3) = 20(3) = 60 feet
The time taken for the bolt to hit the elevator is 3 seconds, at a height of 60 feet.

Percent Increase
Example 1: Ann works in a supermarket for $10.00 per hour. If her pay is increased to $12.00, then what is her percent increase in pay?
Analysis: When finding the percent increase, we take the absolute value of the difference and divide it by the original value. The resulting decimal is then converted to a percent.
Answer:
20% increase
Step-by-step explanation:
Percent increase = (difference) / original *100 percent
= (12-10)/10 * 100percent
= 2/10 *100 percent
= 1/5 * 100 percent
=.2 * 100 percent
= 20%
The numbers 4 through 14 are placed in a
bowel and drawn at random then replaced
after being drawn. What is the probability of
drawing the number 14 and then a number
less than 12?
The probability of drawing the number 14 is 1/10 (because there are 10 different numbers to pick from). The probability of drawing a number less than 12 is 8/10 (or 4/5 simplified). Multiply the fractions: 1/10 *4/5 = 4/50. Simplify to 2/25. The probability of drawing 14 and then a number less than 12 is 2/25.
The lions little league team drinks a gallon of Gatorade each game. Every player gets a cup as a serving. 1 cup =1/16 gallon. The last game, The lions only used 1/2 gallon of Gatorade. How many cups of Gatorade were served to the players during the last game?
Answer:
8 cups
Step-by-step explanation:
8/16 equals 1/2 gallonThe number of cups of Gatorade served to the players during the last game was 8 cups.
To solve the problem, we need to determine how many cups are in half a gallon, given that 1 cup is equal to 1/16 of a gallon.
First, we establish the conversion factor between cups and gallons:
1 cup = 1/16 gallon
Now, we need to find out how many cups are in 1/2 gallon. To do this, we multiply the amount of Gatorade used in the last game by the conversion factor:
Cups served = (1/2 gallon) * (16 cups / 1 gallon)
Performing the multiplication:
Cups served = 1/2 * 16
Cups served = 8 cups
Therefore, 8 cups of Gatorade were served to the players during the last game.

Step-by-step explanation:
Part 1) Solve the system by elimination
Let
x----> the cost per can of grape juice
y----> the cost per can of apple juice
we know that
[tex]6x+4y=13.10[/tex] -----> equation A
[tex]4x+6y=13.10+0.60[/tex]
[tex]4x+6y=13.70[/tex] -----> equation B
Solve the system by elimination
Multiply the equation A by -6 both sides

Multiply the equation B by 4 both sides
[tex]16x+24y=54.8[/tex] -------> equation D
Adds equation C and equation D
[tex]-36x-24y=-78.6\\16x+24y=54.8\\----------\\-36x+16x=-78.6+54.5\\-20x=-23.8\\x=1.19[/tex]
Substitute the value of x in the equation A
[tex]6(1.19)+4y=13.10[/tex]
[tex]4y=5.96[/tex]
[tex]y=1.49[/tex]
therefore
The cost per can of grape juice is [tex]\$1.19[/tex]
The cost per can of apple juice is [tex]\$1.49[/tex]
Part 2) Solve the system by substitution
Let
x----> the cost per can of grape juice

[tex]4x+6y=13.70[/tex]
[tex]6y=-4x+13.70[/tex]
[tex]y=-(4/6)x+13.70/6[/tex]
[tex]y=--0.67x+2.28[/tex] -----> equation B
Substitute equation B in equation A and solve for x
[tex]-0.67x+2.28=-1.5x+3.275[/tex]
[tex]1.5x-0.67x=3.275-2.28[/tex]
[tex]0.83x=0.995[/tex]
[tex]x=1.19[/tex]
Find the value of y

Type the correct answer in each box. Use pi= 22/7, and round your answers to the nearest interger. The perimeter of the largest cross section of a sphere is 88 centimeters. The radius is 14 cm. The volume of the sphere is __ cm^3
Answer:
11,499 cm^3
Step-by-step explanation:
The volume of a sphere is given by the formula [tex]V=\frac{4}{3}\pi r^3[/tex]
The radius is given as 14, we plug it into the formula and find the volume:
[tex]V=\frac{4}{3}\pi r^3\\V=\frac{4}{3}(\frac{22}{7}) (14)^3\\V=11498.66[/tex]
rounded to nearest integer, the volume is 11,499
Answer:
r=14 cm
V=11499 cubic cm
Step-by-step explanation:
If the radius of the sphere is r cm, then the perimeter of the largest cross section is the circumference of the circle qith radius r. Thus,
[tex]88=2\pi r,\\ \\r=\dfrac{88}{2\pi}=\dfrac{44}{\pi}=\dfrac{44}{\frac{22}{7}}=\dfrac{44}{1}\cdot \dfrac{7}{22}=14\ cm.[/tex]
Thvolume of the sphere can be calculated using formula
[tex]V=\dfrac{4}{3}\pi r^3.[/tex]
Since r=14 cm, we get
[tex]V=\dfrac{4}{3}\cdot \dfrac{22}{7}\cdot 14^3=\dfrac{4\cdot 22\cdot 2\cdot 14^2}{3}=\dfrac{34496}{3}\approx 11499\ cm^3.[/tex]
g(r)=−(r+11)(r+14)
1) What are the zeros of the function?
Write the smaller r first, and the larger r second.
smaller r____
larger r_____
2) What is the vertex of the parabola
(___,____)
1) What are the zeros of the function?
smaller r: -11, larger r: -14
2) What is the vertex of the parabola
Vertex: (-12.5, 3)
1. Zeros:
The zeros of the function occur when G(r) = 0. So we need to solve the equation:
-(r + 11)(r + 14) = 0
Since the product of two factors is zero when one or both factors are zero, we can set each factor equal to zero and solve for r:
r + 11 = 0 --> r = -11 (smaller r)
r + 14 = 0 --> r = -14 (larger r)
2. Vertex:
The function is given in factored form, which makes finding the vertex a bit easier. The vertex of a parabola in factored form is exactly between the two zeros.
Therefore, the x-coordinate of the vertex is:
(smaller r + larger r) / 2 = (-11 - 14) / 2 = -12.5
To find the y-coordinate (i.e., the function's value at the vertex), we can plug the x-coordinate of the vertex back into the function (G(r)). However, since the function is multiplied by -1, it might be easier to use one of the original zeros (say, r = -11).
G(-11) = -(-11 + 11)(-11 + 14) = 3 (notice how the negative sign cancels out)
