Answer:
610.5
Step-by-step explanation:
First, we have to organize the data. We know that:
Mary the Manager slept for 999 hours,
Cam the Cashier slept for 333 hours,
Teddy the Truck Driver slept for 777 hours,
Sierra the Security Guard slept for 444 hours.
Next, we have to the the median number of hours of sleep.
To find the median:
First, we have to order the numbers from least to greatest. In this problem that is 333, 444, 777, 999. in an odd amount of numbers, like 5, the middle number is the median. In this case, however, there is not an odd amount of numbers, there are 4 numbers. Which means, we have to do the odd number equation:
We have to add the two middle numbers, which are 444, and 777 together, which results in 1,221. Finally, we must divide the result in half, which gives us out final total of 610.5
Hope this helped!

A. (x+1, y+1)
B. (x+0, y+1)
C. (x+2, y-1)
D. (x+1, y-1)
Answer: C
Step-by-step explanation:
We can test point A.
After the dilation, A has coordinates (0, 0).
After the reflection, A has coordinates (0, 0).
Since we know that after the translation, (0,0) has to map onto (2,-1), we know the translation is 2 units right and 1 unit down.

if a smaller square of side 3 cm is cut out from a bigger square of side 9 cm to form a new shape ,What is the perimeter of the new shape formed?
Need to find:
Perimeter of new square formed?[tex]~[/tex]
Solution:
Side of smaller square = 3cm.Side of Bigger square = 9cm[tex]~[/tex]
Using formula:
Perimeter of square = 4 × side[tex]~[/tex]
Perimeter of smaller square:
⟹ 4 × 3
⟹ 12 cm
[tex]~[/tex]
Perimeter of Bigger square:
⟹ 4 × 9
⟹ 36cm
[tex]~[/tex]
Perimeter of new square = Perimeter of Bigger square - Perimeter of smaller square
⟹ 36 - 12
⟹ 24 cm
[tex]~[/tex]
∴ Perimeter of new square formed is 24 cm.

Which equation represents the graph of f(x) = 4x3 - 3x² + 8x - 6 after a reflection over the x-axis?
Step-by-step explanation:
If we have a function,
[tex]f(x)[/tex]
We can rotate the function across the x axis using the rule
[tex] - f(x)[/tex]
So we have function
[tex]f(x) = 4 {x}^{3} - 3 {x}^{2} + 8x - 6[/tex]
[tex]f(x) = - ( {4x}^{3} - 3 {x}^{2} + 8x - 6)[/tex]
[tex]f(x) = - 4x {}^{3} + 3 {x}^{2} - 8x + 6[/tex]

Olivia purchases gift for her mom and grandma for Mother's Day the first is a pair of sunglasses for $16.35and the second is a bracelet her total is $39.75 how much did she spend on the bracelet
Answer:
$23.40
Step-by-step explanation:
Since we know that the pair of glasses is $16.35 and the total of both the items is $39.75, we have to subtract the costs to get the cost of the bracelet. (39.75-16.35) Take your time to subtract and the answer is 23.4. Since we are dealing with money, make sure to add a 0 after the 4, there has to be 2 digits in money after the decimal point and if needed add the dollar sign.
(a+b)(a-b)(b-a)
help please :)
Answer:
a^2b -a^3 +b^3 +ab^2 - 2a^2b
Step-by-step explanation:
(a+b)(a+b) = a^2 + ab + ab + b^2 which simplifies to a^2 + b^2 + 2ab
(a^2 + b^2 + 2ab)(b-a) = a^2b + -a^3 + b^3 -ab^2 + 2ab^2 -2a^2b which simplifies to a^2b -a^3 +b^3 +ab^2 - 2a^2b

14x + 11 > -227 I NEED HEP
Answer: [tex]x < -27.7142857[/tex]
Step-by-step explanation:
First, you move 11 to the right side, resulting in 14x > -338
Then you divide -388 by 14, which is 27.7142857, so the final statement is
[tex]x < -27.7142857[/tex]Could you give me the brainiest please if I am right?
Answer:
x > -17
Step-by-step explanation:
1. You would subtract 11 from both sides. Like this (14x + 11 - 11 > -227-11)
2. Simplify it (14x > -227 - 11)
3. Next, you would subtract -227 by 11 which will give you -238 (14x > -238)
Isolating the X:
1. Divided both sides by 14 (14x/14) and (-238/14)
2. Simplify the fraction (x > -238/14)
3. You would have to find the GCF of the numerator and the denominator (x > -17 · 14/1 · 14)
4. You factor out and cancel the GCF (x > -17)

Solve each two-step inequality and graph the solution set on a number line -17 < 3-5x
Answer:
[tex]x < 4[/tex]
Step-by-step explanation:
Given the following question:
[tex]-17 < 3-5x[/tex]
In order to find the answer, we will solve the inequality as if it is a regular two-step equation and then we will plot the answer on the number line.
[tex]-17 < 3-5x[/tex]
[tex]-17 < 3-5x=3-5x > -17[/tex]
[tex]3-5x > -17[/tex]
[tex]3-3=0[/tex]
[tex]-17--3=-20[/tex]
[tex]5x=-20[/tex]
[tex]\frac{5x}{5}=x[/tex]
[tex]20\div5=-4[/tex]
[tex]x < 4[/tex]
When plotting inequalities on the number line keep a few things in mind:
. 4 is greater than x, so the line will go towards the opposite direction of four
. < is a greater sign, it's not a greater or equal to sign (≤) which means it will be an open dot.
Hope this helps.

A water tank is built in the form of a right rectangular prism and it can hold 136 cubic
feet of water when it is full. Its length is 8.1 ft and its width is 4.1 ft. Find the height of
the water tank in feet. Round your answer to the nearest tenth if necessary.
Answer:
4.1 ft
Step-by-step explanation:
Got it correct on delta 2023
The height of the water tank in feet is 4.1 feet to the nearest tenth.
What is Rectangular Prism?Rectangular prism is a three dimensional shape which consist of six faces. The two faces are at the top and bottom and the other faces are lateral faces.
Given that,
A water tank is built in the form of a right rectangular prism and it can hold 136 cubic feet of water.
Volume of the tank = 136 feet³
Length, l = 8.1 feet
Width, w = 4.1 feet
The formula to find the volume of a rectangular prism is,
Volume = l × w × h, where h is the height of the tank.
Substituting,
8.1 × 4.1 × h = 136
h = 136 / (8.1 × 4.1)
h = 4.095 ≈ 4.1 feet
Hence the height of the tank is 4.1 feet.

Answer:
-12, 2
Step-by-step explanation:
X may be on the left of W, then X = -5 - 7 = -12
X may be on the right of W, then X = -5 + 7 = 2
Answer:
Locations of X: 2, -12
Step-by-step explanation:
We know that W lies at -5. To figure out where the other X's are located, you need to do -5 ± 7, since the range is 7.
So let's first try -5 + 7:
-5 + 7 = 2
The first location of X can be at 2.
Now let's try -5 - 7:
-5 - 7 = -12
The second location of X is -12.
So, the answer is that X is located at 2 and -12

Answer:
Shirt costs $10.50, pants cost $27Step-by-step explanation:
Set equations as follows3s + 2p = 85.54s + 3p = 123Solve the system by eliminationMultiply the first equation by 4 and the second one by 3 and subtract equations
4(3s + 2p) - 3(4s + 3p) = 4(85.5) - 3(123)12s + 8p - 12s - 9p = 342 - 369- p = - 27p = 27Find the value of s

Keith served ice cream to his 3 children.He gave each child
4 2/3 onces.How many onces did he served altogether?
Answer:
14 ounces!
Step-by-step explanation:
It's actually quite simple, it's easy too overlook these questions but don't worry, I will help
All you really have to do is count up, what I do is temporarily forget about the fractions I focus on the main number (which in this case is 4) you want to times 4 by the amount of children so (3) 4×3=12
Now the fraction part, all you have to do is count up! 2/3, then 3/3 then 1 1/3 then 1 2/3 then 2!
Now add the original number by the result of the fraction number so 12+2= 14!
