Answer: The equation to describe the situation is p-3= 17
And, the total weight of the basket of apples was 20 pounds.
Step by step: Now, to write an equation to describe the situation. And to find the total weight of the basket of apples.
So, the basket of apples total weighed = p pounds
Liang ate apples weighed = 3 pounds.
And the apples left for the pies weighed = 17 pounds.
Now, to write an equation describing the situation:
p-3=17 .
Thus, the equation is p-3=17
Now, to get the total weight of the basket of apples:
p-3=17
adding both sides by 3 we get : p=20
Hence, the basket of apples total weighed = 20 pounds.
Therefore, the equation to describe the situation is p-3=17
And, the total weight of the basket of apples was 20 pounds.

If x4≤f(x)≤x2 for x in [−1,1] and x2≤f(x)≤x4 for x<−1 and x>1, at what points c do you automatically know limx→c f(x)? What can you say about the value of the limit at these points?
You would know that
[tex]\displaystyle\lim_{x\to\pm1}f(x)=1[/tex]
It follows from the sandwich/squeeze theorem: for instance,
[tex]x^4 \le f(x) \le x^2 \implies \displaystyle\lim_{x\to-1}x^4 \le \lim_{x\to-1}f(x) \le \lim_{x\to-1}x^2 \implies 1 \le \lim_{x\to-1}f(x) \le 1 \\\\ \implies \lim_{x\to-1}f(x)=1[/tex]
Work out an estimate for the value of
41.2 x 19.8
——————-
0.49
Answer:
820
Step-by-step explanation:
41.2 * 19.8 = 41 *20 = 820
41.2
In this tenth value is 2 which is less than 5. So ignore it and write the whole number alone. 41
19.8
In this tenth value is 8 awhich greater than 5. So add 1 to whole part and write.
19+1 = 20

.4898
Step-by-step explanation:
Just go to a ztable and match the values (I've attached the one i use below)
if it's negative subtract one
if it's z># then subtract one
so for 1.37 go to the table and find the value (.8770) and subtract 1
Go to 1.16 on the z table (.8770), subtract 1 (1-.8770) and then do it again
for the last one you need to take a z value of 0 (.5) and then the value for 2.32 (.9898) and subtract them

21.) WX 22.) VW 23.) WY 24.) VX 25.) WZ 26.) VY
Answer:
WX=10; VW=22; WY=20; VX=32; WZ=30;VY=42
Step-by-step explanation:
1)WX=XY=XZ/2=20/2=10
2)VW=VZ-WX-XY-YZ=VZ-3*WX=52-3*10=52-30=22
3)WY=WX+XY=2*WX=2*10=20
4)VX=VW+WX=22+10=32
5)WZ=WX+XY+YZ=3*WX=3*10=30
6)VY=VZ-YZ=52-10=42
The points V, W, X, Y and Z are collinear. The indicated lengths are
[tex]WX=10\\VW=22\\WY=20\\VX=32\\WZ=30\\VY=42[/tex]
Given :
points V, W, X, Y and Z are collinear, VZ= 52, XZ =20, and WX=XY=YZ
Lets make diagram using the given information
The diagram is attached below
XY=YZ
XZ=20, so [tex]XY+YZ=20\\Both XY and YZ are same\\XY+XY=20\\2XY=20\\Divide \; by \; 2\\XY=10[/tex]
[tex]WX=XY=YZ \\XY=10\\WY=10\\YZ=10\\[/tex]
Now we find out VW
[tex]VW+WX+XY+YZ=52\\VW+10+10+10=52\\VW+30=52\\Subtract \; 30\\VW=52-30\\VW=22[/tex]
Now we find the indicated length
[tex]WX =10[/tex]
[tex]VW=22\\WY=WX+XY=10+10=20\\VX=VW+WX=22+10=32\\WZ=WX+XY+YZ=10+10+10=30\\VY=VW+WX+XY=22+10+10=42[/tex]

What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The polynomial is,
⇒ x² - x - 3 = 0
Now,
We can solve the equation as;
⇒ x² - x - 3 = 0
⇒ x² - x - 3 + 3 = 3
⇒ x² - x = 3
⇒ x² - x + 1/4 = 3 + 1/4
⇒ (x - 1/2)² = 13/4
⇒ x - 1/2 = ±√13 / 2
⇒ x = ±√13 / 2 + 1/2
Hence, Bao Yu first step to solve the equation is,
⇒ adding –3 to both sides of the equation

Andrew has a coupon for 20 % off of the price of any CD. If he purchases a CD originally priced at $16, what will the discounted price be?
Solve the above problem by using decimals.
Answer:
If you want to turn a percentage into a fraction divide by 100:
20%/100 = 0.2
0.2*16 = 3.2$
and if you want to turn a decimal into a fraction multiply by 100.
His discounted price will be 3.2$.
Have a nice day! :-)
and if you have questions please ask!
Percentage is the part of a whole given as a fraction of the hundred. The discounted price of the CD is $12.8.
Given information-
Andrew has a coupon for 20 % off of the price of any CD.
The price of the CD purchased by the Andrew is $16.
PercentagePercentage is the part of a whole given as a fraction of the hundred.
As the Andrew has a coupon of 20 percent, the 20 percent will be off whatever he buys. Now the discount price for the $16 priced CD is equal to the 20 percent of the 16. Thus the discount is,
[tex]d=\dfrac{16\times20}{100} \\ [/tex]
[tex]d=3.2[/tex]
Thus the discount on the CD is 3.2.
Now the discounted price of the CD is equal to the difference of the price of the CD and the discount. Thus the discounted price of the CD is,
[tex]P=16-3.2[/tex]
[tex]P=12.8[/tex]
Thus the discounted price of the CD is $12.8.

15. A lamp is on sale at £22.05 This is a 10% reduction of the normal price. What was the price of the lamp before the reduction?
Answer:
£24.26 (rounded to 2dp) or full answ £24.255
Step-by-step explanation:
find 1% of 22.05= 0.2205
0.2205*10=2.205(10%)
add this to the 90%(£22.05+2.025)= 24.255
=24.26(rounded to 2dp)
The price of the lamp before the reduction will be £24.5.
What is mean by Percentage?
A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
To Calculate the percent of a number , divide the number by whole number and multiply by 100.
Given that;
The sale price of the lamp = £22.05
This is a 10% reduction of the normal price.
Now,
Let the price of the lamp before the reduction = x
So, We can formulate;
⇒ x - (10% of x) = £22.05
⇒ x - 10x/100 = £22.05
⇒ (100x - 10x)/100 = £22.05
⇒ 90x / 100 = £22.05
⇒ 90x = £22.05 x 100
⇒ 90x = £2205
⇒ x = £2205/90
⇒ x = £24.5
Thus, The price of the lamp before the reduction will be £24.5.

The minimum number of tiles that will be needed to completely cover the countertop to its edges is 96.
What is an area?The space occupied by any two-dimensional figure in a plane is called the area. The space occupied by the rectangle in a two-dimensional plane is called the area of the rectangle.
The number of tiles will be calculated by calculating the area of the rectangular kitchen and the area of a tile then dividing the whole area by the area of a tile.
Area of kitchen,
A(k) = 64 x 24 = 1536 Square inches
Area of a tile,
A(T) = 4 x 4 = 16 square inches.
Divide the area of the kitchen by the area of a tile.
