Choose the correct simplification of the expression (12x2y3z4)(3x9y6z8).
36x18y18z32
15x18y18z32
36x11y9z12
15x11y9z12
Answers
36x¹¹y⁹z¹²
Explanation:
Before we begin, remember the following rules:
xᵃ * xᵇ = xᵃ⁺ᵇ
xᵃyᵇ * xⁿy° = xᵃ⁺ⁿ yᵇ⁺°
Now, for the given we have:
(12x²y³z⁴)(3x⁹y⁶z⁸)
Combining like terms and applying the above rules:
(12)(3) * x²⁺⁹ * y³⁺⁶ * z⁴⁺⁸
36x¹¹y⁹z¹²
Checking the options we have, we would find that this corresponds to the third option.

where a and b are the legs and c is the hypotenuse
so a = 6 and c = 8
lets solve for b
6^2 + b^2 = 8^2
36 + b^2 = 64
b^2 = 64 - 36
b^2 = 28
b = sqrt(28)
b = 5.29

Kid's name Height before the summer Height after the summer Henry 120 cm cm Lisa 130 cm cm Kate 140 cm cm Erik cm 151.2 cm Matt cm 105 cm There is a 5 percent increase
Answers
The following chart is completed below;
Henry = 126 cm
Lisa = 136.5 cm
Kate = 147 cm
Erik = 144 cm
Matt = 100 cm
Copy and complete the table?
Kid's name: Henry
Height before the summer: 120 cm
Height after the summer: 126 cm
Height after the summer = 120 + 5% of 120
= 120 + 0.05×120
= 120 + 6
= 126 cm
Kid's name: Lisa
Height before the summer: 130 cm
Height after the summer: 136.5 cm
Height after the summer = 130 + 5% of 130
= 130 + 0.05×130
= 130 + 6.5
= 136.5 cm
Kid's name: Kate
Height before the summer: 140 cm
Height after the summer: 147 cm
Height after the summer = 140 + 5% of 140
= 140 + 0.05×140
= 140 + 7
= 147 cm
Kid's name: Erik
Height before the summer: 144 cm
Height after the summer:151.2 cm
Height after the summer = x + 5% of x
151.2 = x + 0.05x
151.2 = 1.05x
x = 151.2/1.05
x = 144
Kid's name: Matt
Height before the summer: 100 cm
Height after the summer: 105 cm
Height after the summer = x + 5% of x
105 = x + 0.05x
105 = 1.05x
x = 105/1.05
x = 100

Jed figures the promwill cost hin $160. He has saved $46 and can earn $6 an hour at his job. How many hours will he have to work?
Answers
6x + 46 = 160
Now that we have our equation,, we can start solving by moving our constant to the right side of the equation and changing the sign.
6x = 160 - 46
Now subtract the numbers on the right side.
6x = 144
Finally,, divide both sides of the equation by 6 to get your final answer.
x = 19
This means that Jed needs to work 19 hours to pay for prom.

Answers
volume of box = 312.375 in²
Explanation:
The volume of a rectangular box can be measured as follows:
volume = length* width * height
From the givens we have:
length = 8.5 in
width = 5.25 in
height = 7 in
Substitute with the givens in the above equation to get the volume as follows:
volume = length * width * height
volume = 8.5 * 5.25 * 7
volume = 312.375 in²

400 hamburgers
2) The difference between these temperatures 212-32=180
180
Any number that is more than 32 and less than 212 is between this temperatures.
For example 40, and 136 lie between 32 and 212.
3) 1000, 100, 10, 1...
We can see that every next number 10 times less than previous number,
so after 1 should be 1/10=0.1
If it is written as fraction 1/10, if it is written as decimal 0.1.
2.If this is for the halfway point between the two, it is 122 degrees. If it is difference, it is 180 degrees.

If sin (13y-5) = cos (2y+5), then what is the value of y?
Answers
Given sin (13y-5) = cos (2y+5)
We have a formula regarding complementary angles that is given as follows :-
If sin(A) = cos(B), then A + B = 90 degrees.
where A and B are complementary angles.
Comparing it with given information, we get A = (13y-5) and B = (2y+5).
So the sum of two angles A = (13y-5) and B = (2y+5) would be 90 degrees.
(13y-5)° + (2y+5)° = 90°
13y + 2y - 5 + 5 = 90°
15y = 90°
y = 6°
Hence, final answer is y = 6 degrees.
Jamie’s dad put 12 gallons of gasoline in his car the gasoline costs 3.25$ a gallon how much did Jamie’s dad pay for the gasoline
Answers
To find out how much Jamie's dad paid for the gasoline, we need to multiply the amount of gasoline he bought by the cost per gallon.
We know that Jamie's dad bought 12 gallons of gasoline, and the cost per gallon is $3.25.
So, let's multiply these two numbers together.
First, take the 12 gallons of gasoline.
Then, multiply that number by the cost per gallon, which is $3.25.
So, 12 × $3.25 equals $39.00.
Therefore, Jamie's dad paid for the gasoline.
answer: $39.00

What kinds of symmetry do these letters and numbers have? Choosing best answer? What kind(s) of symmetry do these have? F 3 E Point, line, plane, or none?
Answers
Letter F: none
Number 3: line and plane simmetry
Letter E: line and plane simmetry
Explanation:
1) point symmetry means that a rotation of 180° returns the same original figure.
None of the objects given result the same when you rotate them 180°, so none has point symmetry.
2) line simmetry is when the reflection accross a line returns the same original figure.
Both number 3 and letter E have symmetry accros a horizontal line that crosses them by the middle, which F does not.
3) Plane simmetry: exactly as with the line,number 3 and letter E have simmetry accross a plane that crosses them by the middle.

What expressions are equivalent to 6-10/6-4
Answers
To simplify the expression 6 - 10/6 - 4, divide 10 by 6 and subtract the result from 6, then subtract 4 from the previous result. The simplified expression is 0.33.
Explanation:To simplify the expression 6 - 10/6 - 4, you need to follow the order of operations which is Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).
To simplify the expression, we can perform the division first: 10/6 = 1.67.
Substituting the result back into the expression, we have: 6 - 1.67 - 4.
Next, we can perform the subtraction from left to right: 6 - 1.67 = 4.33, then 4.33 - 4 = 0.33.
Therefore, the expression 6 - 10/6 - 4 simplifies to 0.33.

Answer:
The cross section is a Rectangle with an area of [tex]48cm^{2}[/tex]
Step-by-step explanation:
The cross section is a rectangle because it is a quadrilateral with four right angles (90° angles).
The area of a rectangle is the product of the length and width. In this case is [tex]8cm[/tex] and [tex]6cm[/tex] because the cross section is perpendicular to to is base therefore parallel to the side with this measures. We calculate it:

Final answer:
Mrs. Graham used an observational study design to record students' activities during study halls, observing without intervening or manipulating the environment.
Explanation:
The research design that Mrs. Graham used by recording what each student did during study hall for one month is best described as an observational study. In this type of research, the observer does not intervene or manipulate the environment or subjects but simply records observations of what is occurring naturally. Consequently, Mrs. Graham's study aimed to systematically identify and examine how students use their time without altering their behavior intentionally, which is different from an experimental study where the investigator would manipulate a variable to see its effect.
Annie Mae collects snow globes that come in cube-shaped boxes as shown.
Please contact your teacher immediately if you do not see the diagram.How does the change in the length of the sides from the smaller cube to the larger cube affect the volume?
Question 3 options:
The volume increases by a factor of 64.
The volume increases by a factor of 27.
The volume increases by a factor of 9.
The volume increases by a factor of 16.
Answers
First find the volume of both cubes and then take the ratio of lager to smaller cube to the factor of increase.
volume of smaller cube= v= 4³ = 64 in³
volume of larger cube= V= 12³ = 1728 in³
Now find the factor= V/v =1728/64 =27
So volume increase by the factor of 27

Answers
There were 16 penguins on the ice at the start.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
Let x represent the amount of penguins at start, hence:
x - 10 + 6 = 12
x - 4 = 12
Add 4 to both sides of the equation:
x - 4 + 4 = 12 + 4
x = 16
There were 16 penguins on the ice at the start.
