Step-by-step explanation:
a polynomial is an expression consisting of variables (also called indeterminates) and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponentiation of variables. An example of a polynomial of a single indeterminate x is x2 − 4x + 7.

pls help find the value of x
Use the table below to find what the out put will be when the input is 54. Explain
Answer:
The answer is 15
Step-by-step explanation:
adding 3 to y for each time 1 is added to y. since you start with a base of 9, we can conclude this answer by taking 3 times 15, which is 45, then adding 9, which makes 54. Like this:
0 | 9
1 | 12
2 | 15
...
13 | 48
14 | 51
15 | 54

round to the nearest tenth
Answer:
Step-by-step explanation:
Say you wanted to round the number 838.274. Depending on which place value you'll round to, the final result will vary. Rounding 838.274:
Rounding to the nearest hundred is 800
Rounding to the nearest ten is 840
Rounding to the nearest one is 838
Rounding to the nearest tenth is 838.3
Rounding to the nearest hundredth is 838.27
Basic Rules of Rounding
When you "round to the nearest _____" regardless of what goes in the blank the steps are nearly always the same:
Identify which place value you are rounding to. The smaller the place value, the more accurate the final result will be.
Look to the next smallest place value, the digit to the right of the place value you're rounding to. For example, if you want to round to the nearest ten you'd look at the ones place.
If the digit in the next smallest place value is less than five (0, 1, 2, 3, or 4), you leave the digit you want to round to as-is. Any digits after that number (including the next smallest place value you just looked at) become zeros, or drop-off if they're located after the decimal point. This is called rounding down.
If the next smallest place value is greater than or equal to five (5, 6, 7, 8, or 9), you increase the value of the digit you're rounding to by one (+1). Just like before, any remaining digits before the decimal point become zeros, and any that are after the decimal point are dropped. This is called rounding up.
Round to the Nearest Hundred: 3250
Identify the hundreds digit: the 2 in 3250
Identify the next smallest place value: the 5 in 3250
Is that digit greater than or equal to five? Yes, so round up.
Increase the hundreds digit by one, so 2 becomes 3. Every digit after becomes a zero.
3250 rounded to the nearest hundred is 3300
Round to the Nearest Ten: 323.5
Identify the tens digit: the 2 in 323.5
Identify the next smallest place value: the 3 in 323.5
Is that digit greater than or equal to five? No, so round down.
The tens digit stays the same at 2. Every digit after becomes a zero. Digits after the decimal point are dropped.
323.5 rounded to the nearest ten is 320
Round to the Nearest Ten: 499
Identify the tens digit: the first 9 in 499
Identify the next smallest place value: the second 9 in 499
Is that digit greater than or equal to five? Yes, so round up.
The tens digit increases by one. Since 9+1=10, you need to carry the 1 and add it to the digit in the hundreds place. Each digit after becomes a zero.
499 rounded to the nearest ten is 500
Round to the Nearest Tenth: 0.74
Identify the tenths digit: 7 in 0.74
Identify the next smallest place value: the 4 in 0.74
Is that digit greater than or equal to five? No, so round down.
The tenths digit stays the same at 7. Since the remaining digits are after the decimal point you just drop them.
0.74 rounded to the nearest tenth is 0.7
Round to the Nearest Hundredth: 3.141
Identify the hundredths digit: the 4 in 3.141
Identify the next smallest place value: the second 1 in 3.141
Is that digit greater than or equal to five? No, so round down.
The hundredths digit stays the same at 4. Drop the digits to the right of 4.
3.141 rounded to the nearest hundredth is 3.14

What is the area of the figure?
Answer:

Step-by-step explanation:
Area of the shaded region = Area of exterior circle with radius (3 +2 = 5) units - Area of interior circle with radius 3 units
[tex] = \pi {(5)}^{2} - \pi {(3)}^{2} \\ \\ = \pi( {(5)}^{2} - {(3)}^{2} ) \\ \\ = 3.14 \times (25 - 9) \\ \\ = 3.14 \times 16 \\ \\ = 50.24\\ \\ \approx 50.2 \: {units}^{2} [/tex]

HELP i need to find area AND perimeter there is a triangle and a rectangle
Answer:
perimeter of this figure is = 54 cm
and area of traingle is = 1/2*base *height
so = 1/2*8*6
=. 24cm*cm
and area of rectangle = length * breadth
area = 112cm*cm
so total area = 112+ 24 = 136cm*cm
hope it helps and your day will full of happiness
Answer:
138 cm^2 = Area . 54 cm = Perimeter
Step-by-step explanation:
Find the area of the triangle- b * h = A
2
8 * 6 = A
2
48/2 = A
24 = A
Find the area of rectangle- l * w = A
16 * 7 = A
112 = A
Add the areas together. 24 + 112 = 136 cm^2
Perimeter is adding up all the sides. s + s + s + s + s
16 + 7 + 8 + 10 + 13 = 54 cm

An architect wants to create a rectangular sun
porch in a house. He wants it to have a total area of
144 square feet, and it should be 8 feet longer than
it is wide. Find the length and width of the
rectangular garden. Round your answers to the
nearest hundredth.
Answer:
68 +76
So we do 144/2=72
since its an 8 foot difference subtract 72-4 and 72+4 we get 68 and 76 hope this helped!
. Bryon competes on the school debate team. He won 0.40 of the debates in which he participated. Which statement is not true about Byron's debates?
Answer: See explanation
Step-by-step explanation:
You didn't give the options but let me help out.
Since Bryon won 0.40 of his debate, this means that he won 40% of his debate. 40% converted to fraction equals 40/100 = 2/5.
Since he won 40%, it means that he lost (100% - 40%) = 60%. He lost 3/5 and won 2/5.
bill paid $35.99 in tax on a laptop that cost $449.99. about what percent sales tax did bill pay
Answer:
Bill paid about 7% sales tax.
Step-by-step explanation:
First, to find the value of 1%, I divided $449.99 by 100, which gave me 4.4999. I then divided the amount paid for tax by the value of 1%. That;s $35.99 ÷ $4.4999 = 7.199439887977596. Obviously, you can't put that in your math homework, plus the question says "about," so you're going to round. Because the first number after the decimal point is less than five, you round down. Therefore, the sales tax is about 7%.

sixteen less than a number squared
Answer:
16-x^2
Step-by-step explanation:
How to solve 4 x = 16
Answer:
x=4
Step-by-step explanation:
First we Divide both sides by 4 so we can just get x
For example
4x=16
x=4 We divided both sides by 4 because we need to get x and the reason why we also divided 16 by 4 is because what you do to one side you do to the other to keep the values consistent

A photo album costs $10.49 before discount and tax.
There is a 30% off discount. After the discount, a 6%
sales tax is added.
What is the total after discount and tax?
Answer:
Total after tax and discount is $7.78
Step-by-step explanation:
(10.49×0.3)= 3.15
10.49 - 3.15 = 7.34
(7.34×0.06)= 0.44
7.34 + 0.44 = 7.78
PLEASE HELP ASAP ILL GIVE YOU 30 POINTS Jamie is excited for spring break this year. Her family is planning a vacation! She fully intends to take 20 pictures each day. checking her phone before leaving she notices she has 75 pictures already on the phone.
Given that the vacation will last a full seven days and Jamie's phone can hold a total of 200 pictures. How many pictures will she need to delete an order to make enough room in her phone for vacation photos?
Answer:
15 photos
Step-by-step explanation:
one can start off by first seeing how many photos will be taken on the vacation. We can do that by multiplying the days with how many photos will be taken for each- so 20×7= 140. Then we can take the total amount of photos the phone cam hold-200 subtract what we already have 200-75= 125 thats how much space if left but we need more (140). So the. we can start making quick guesses by taking 5 from 75 and see what we get then taking another 5 and another if needed we get 60 that finally gives when subtracted from 200- 200-60=140 the amount of space we need. Then finally we can just do 75-60 to get the total amount of photos we must delete. 75-60= 15
