Which number is four thousand times larger than 1.1 x 103 ? A) 1.1 x 106 B) 1.1 x 107 C) 4.4 x 106 D) 4.4 x 107
The answer to this problem is D
Answer: Hello!
I think that 1.1 x 103 is maybe bad written, and you wanted to write 1.1x10^3, i will solve this for this last one.
We are looking for a number that his four thousand times larger than 1.1x10^3, this number is equivalent to 4000*1.1x10^3
and we know that 4000 = 4x10^3, then we are looking for:
(4x10^3)*(1.1x10^3) = (4*1.1)x10^(3 + 3) = 4.4x10^6
So the correct answer is the option C : 4.4x10^6
-3a + 4 ≥ -16
Solve, and show your work.
Answer:
a ≤ 20/3
Step-by-step explanation:
Subtract 4 from both sides, obtaining:
-3a ≥ -20. Dividing both sides by -3, we get a ≤ 20/3.
Note that because this is an inequality, and because we've divided all terms by a negative number, we must change the direction of the inequality symbol from ≥ to ≤.

point b has the points (5 -2) is rotated 180 about the origin, its image has coordinates
When rotating a point 180 degrees about the origin, you are simply inverting the points.
(5, -2) rotated 180 degrees results in (-5, 2).
To rotate point B(5, -2) 180 degrees about the origin, its image would have coordinates (-5, 2).
Explanation:To rotate a point about the origin, we can use the formula (x', y') = (-x, -y). In this case, point B has coordinates (5, -2). To rotate it 180 degrees about the origin, we substitute the coordinates into the formula:
(x', y') = (-5, 2)

Answer: f(5) = 27.The value of f(5) is 27 of function f(x) = 1/9(3)ˣ
What is the function?The function is defined as mathematics expression defines a relationship between one variable and another variable. When we say that a variable quantity y is a function of a variable quantity x, we indicate that y depends on x and that value of x determines what value of y will be. This relationship can be expressed as follows: y = f (x)
What is Exponential Function?An exponential function is defined as function has a constant as its base and a variable as its exponent.
In mathematical form an exponential function is a function of form f (x) = aˣ, where “x” is a variable and “a” is a constant which is called the base of the function.
For the function f defined by f(x) given as :
f(x) = 1/9(3)ˣ ,
To determine the value of f(5).
f(x) = 1/9(3)ˣ,
Substitute the value of x = 5 in the function,
f(5) = 1/9(3)⁵ , [ 3⁵ = 243 ]
f(5) = 1/9(243),
f(5) = 27
Hence, the value of f(5) is 27.

Find the perimeter of the figure at the right.
The perimeter of the figure is 82.275cm.
In order to find this, we must first find the length of the arc portion. For this we will use circumference of a circle formula and then cut the amount in half (since it is a semi circle). The formula is below:
2[tex]\pi[/tex]r = C
We know the radius is 9 since it is half of the 18 that is the full diameter.
2[tex]\pi[/tex](9) = C
28.275 = C
Now we add that to the 3 other sides, which are all 18.
28.275 + 18 + 18 + 18 = 82.275

Well, you already know how to simplify these equations. There is nothing complicated about these, although it may look like they are. For problem 1, (2x^2)^3 is just multiplying the exponents. Add them together, and the numerator is 2x^5. The denominator is multiplying exponents again. 4x^4 * 3x^3 gives you 12x^7. The final answer is 2x^5 over 12x^7. Focus on the questions and keep your patience. You have the sheet that tells you all the rules for simplifying these equations. It shouldn't take too long. Just focus.

In January they saved $120 and recorded +$20 at the end of the month. What should they record for the month of February if they only saved $80 that month? Explain.
They should subtract $ -20 because they went behind on how much they planned to save. Now this question can be tricky because some might say they lost 0 because they already had an extra $20 but it is only asking for the month of February and is only asking for each month not the entire year.
Answer:
-$20
Step-by-step explanation:
We are given that
A family wants to save each month =$100
In January, they saved=$120
They recorded at the end of the month January=+$20
In February, they saved=$80
We have to find that what should they record at the end of month February if the saved $80.
Family wants to save each month=$100
But in February,
The family saved only=$80
Therefore, they recorded at the end of month February=80-100=-$20
Hence, they should record -$20 for the month of February if they saved $80 . Because they did not achieve their target .They have $20 lack from their monthly target.

Geometry- Examine the diagrams below. What is the geometric relationship between the labeled angles? What is the relationship of their measures? Then, use the relationship to write an equation and solve for x.
The geometric relationship, relationship between the measure of the labelled angles, and the value of x in each case are:
a. Geometric Relationship: vertical angles
Relationship of their measures: they are equal
Equation: (3x + 5) = (5x - 5)
x = 5
b. Geometric Relation: straight line angles
Relationship of their measures: their sum equals 180
Equation: (4x + 150) + 2x = 180
x = 5
a. (3x + 5) and (5x - 5) are vertical angles opposite to each other.
The geometric relationship is "vertical angles are congruent".
This means (3x + 5) and (5x - 5) are of equal measure.Therefore equation from the geometric relation is:[tex](3x + 5) = (5x - 5)[/tex]
Solve for x[tex]3x + 5 = 5x - 5[/tex]
Collect like terms[tex]3x - 5x = -5- 5\\\\-2x = -10[/tex]
Divide both sides by -2[tex]x = 5[/tex]
b. (4x + 150) and 2x are angles that lie on a straight line.
Angles on a straight line are supplementary and will add up to give you 180 degrees.
The geometric relationship is therefore "angles on a straight line are supplementary".
Therefore equation from the geometric relation is:[tex](4x + 150) + 2x = 180[/tex]
Solve for x[tex]4x + 150 + 2x = 180[/tex]
Add like terms[tex]6x + 150 = 180[/tex]
Subtract 150 from both sides[tex]6x = 180 - 150\\\\6x = 30[/tex]
Divide both sides by 6
[tex]x = 5[/tex]
Therefore, the geometric relationship between the given measures of the angles, their equation from the relation and the x value of each are:
a. Geometric Relationship: vertical angles
Relationship of their measures: they are equal
Equation: (3x + 5) = (5x - 5)
x = 5
b. Geometric Relation: straight line angles
Relationship of their measures: their sum equals 180
Equation: (4x + 150) + 2x = 180
x = 5

What is the unknown digit
What Is 2x+50=4x+25
Can Someone Help Me Find The Answer!!!!
2x + 50 = 4x + 25
To isolate x, first subtract 50 from both sides of the equation.
2x + 50 - 50 = 4x + 25 - 50
2x = 4x - 25
Then, subtract 4x from both sides.
2x - 4x = 4x - 25 - 4x
-2x = -25
Lastly, divide both sides by -2.
x = 12.5
Check work
Substitute 12.5 for every x in the equation.
2(12.5) + 50 = 4(12.5) + 25
25 + 50 = 50 + 25
75 = 75
As you can see, the statement is true; 12.5 is correct.

a utility worker is 5.5 feet tall and is casting a shadow 4 feet long at the same time a nearby utility pole casts a shadow 20 feet long write and solve a proportion to find the height of the utility pole
So this is essentially a proportion problem. They want you to be able to recognize a relationship between the two. The easiest way to go about this is to draw a picture (I have included one). What you want to do is notice that you are given both shadow lengths. This is essentially going to be your first step to creating the proportion.
Understanding that we know the shadow lengths, we can turn these into a fraction such as so:
4ft/20ft.
Now that we know that, we need to look at are unknown. Our unknown is the height of the utility pole. We can solve this by substituting for X since we know the utility worker is 5.5 ft tall.
Your fraction for that would look like:
5.5ft/X
Make sure to always make your top to top match, such as since I put the utility worker's shadow on top, I need to put his height on top.
Now we can solve.
4ft/20ft =5.5ft/X
We need to cross multiply to get an equation we can work with. If we cross multiply, Your equation will look like:
4x = 110ft
This is a simple one step equation. Divide both sides by 4 to get your answer.
x= 27.5ft.
This means your Utility pole's height is 27.5ft.
To find the height of the utility pole, set up a proportion with the utility worker's height and shadow length as one ratio, and the utility pole's height and shadow length as the other ratio. Solve the proportion by cross-multiplying and simplifying the equation. The height of the utility pole is 27.5 feet.
Explanation:To find the height of the utility pole, we can set up a proportion with the utility worker's height and shadow length as one ratio, and the utility pole's height and shadow length as the other ratio. Let's call the height of the utility pole 'x'. The proportion can be written as:
(5.5 ft) / (4 ft) = x / (20 ft)
Cross-multiplying, we get:
(5.5 ft) * (20 ft) = 4 ft * x
Simplifying, we find:
x = (5.5 ft * 20 ft) / 4 ft = 27.5 ft
Therefore, the height of the utility pole is 27.5 feet.

Omar has 2 3/4 cups of dough to make Dumplings. If he uses 3/16 cup of dough for each dumpling,how many whole dumplings can Omar make?
Omar can make 14 whole dumplings. You change 2 3/4 cups to an improper fraction ( multiply the denominator and add the numerator ) and you get 11/4. Since you need 3/16 cups for one dumpling you have to find the greatest common denominator which is 16. You multiply 4 by 11 to get the numerator and end up with 44/16. Since you need 3/16 for one whole dumping you divide 44 by 3 and get 14.6 repeating. You cannot have a fraction of a dumpling so you round down and get the answer 14.
suppose you earn 3% on a $1200 deposit for 5 years . explain how the simple interest is affected if the rate is increaced by 1% . what happens if the time is increaced by 1 year
To calculate simple interest, use the formula Simple Interest = Principal × Rate × Time. If the rate is increased by 1%, the simple interest will increase. If the time is increased by 1 year, the simple interest will also increase.
Explanation:To calculate the simple interest on a deposit, you can use the formula:
Simple Interest = Principal × Rate × Time
Now let’s address the first part of the question. If the rate is increased by 1%, the new rate would be 3% + 1% = 4%. Using the same formula, the simple interest would now be:
Simple Interest = $1200 × 0.04 × 5 = $240
Now, let’s move on to the second part of the question. If the time is increased by 1 year, the new time would be 5 years + 1 year = 6 years. Using the same rate of 3%, the simple interest would now be:
Simple Interest = $1200 × 0.03 × 6 = $216
