Answer:
The first one, 2.2289<2.297
Step-by-step explanation:
Answer:
The answer is 2.2289<2.297 because if you look in the hundredths place there is a 9 in 2.297 but in 2.2289 there is an 2 and 9>2 so that is your answer.

In a stationary store,pencils have one price and pens have another price.Two pencils and three pens cost 78 cents.However, 3 pencils and 2 pens cost 72 cents . How much does one pencil cost?
Answer:
12¢
Step-by-step explanation:
Let the unit price of a pencil be x and the unit price of a pen be y.
2x+3y=78¢
3x+2y=72¢
(2x)+3y=78¢
(3x)+2y=72¢
=2x=78¢-3y
=2x/2=78¢/2+3y/2
=x=36¢-1.5y
You then use the equation 3x+2y=72¢.
3(36¢-1.5y)+2y=72¢
=117¢-4.5y+2y=72¢
=117¢-72¢=4.5y-2y
=45¢=2.5y
=45¢/2.5=y
=18¢=y
So a pen costs 18¢.
You then use x=36¢-1.5y
x=36¢-1.5(18¢)
=x=36¢-27¢
=x=12¢
Therefore, a pencil costs 12¢.
Point E is on line segment DF. Given DE = 2x, EF = 2x – 6, and
DF = 3x + 5, determine the numerical length of EF.
Answer: EF =
Answer:
EF is 16.
Step-by-step explanation:
So we know that Point E is somewhere on Line DF. In other words, DE plus EF must equal DF. In an equation, this is:
[tex]DF=DE+EF[/tex]
We are given that DE is 2x, EF is 2x-6, and DF is 3x+5. So, substitute:
[tex](3x+5)=(2x)+(2x-6)[/tex]
Now, solve for x.
On the right, combine like terms:
[tex]3x+5=4x-6[/tex]
Subtract 4x from both sides:
[tex]-x+5=-6[/tex]
Subtract 5 from both sides:
[tex]-x=-11[/tex]
Divide both sides by -1:
[tex]x=11[/tex]
Now that we know x is 11, substitute this back into the equation for EF to find EF.
[tex]EF=2x-6[/tex]
Substitute 11 for x:
[tex]EF=2(11)-6[/tex]
Multiply:
[tex]EF=22-6[/tex]
Subtract:
[tex]EF=16[/tex]
And we're done!

Nax)
a. $6,824.60
b. $6,355.10
c. $6,324.00
d. $6,220.00
Answer:
Option c.
Step-by-step explanation:
It is given that the piecewise function represents the Social Security taxes for 2009.
[tex]Tax=\begin{cases}0.062x & \text{ when } 0< x < 106,800 \\ \$6,621.60 & \text{ when } x > 106,800 \end{cases}[/tex]
We need to find Rachel's security tax if she earned $102,000 in 2009.
Since 102,000 lies in [tex]0<x<106,800[/tex], therefore
[tex]Tax=0.062x[/tex]
Put x=102000.
[tex]Tax=0.062(102000)[/tex]
[tex]Tax=6324[/tex]
So, the Social Security tax is $6324.
Therefore, the correct option is c.

one-half the cube of m subtracted by 4 *
Answer:
[tex]\frac{m^3}{2} - 4[/tex]
Step-by-step explanation:
Required
Determine an expression for the given statement
The expression can be rewritten as:
one-half * the cube of m subtracted by 4
Convert each statement to mathematical expressions:
One half = [tex]\frac{1}{2}[/tex]
The cube of m = [tex]m^3[/tex]
one-half * the cube of m = [tex]\frac{1}{2} * m^3[/tex]
At this stage, we have:
[tex]\frac{1}{2} * m^3[/tex] subtracted by 4
This gives:
[tex]\frac{1}{2} * m^3 - 4[/tex]
[tex]\frac{m^3}{2} - 4[/tex]
Hence, The corresponding expression is [tex]\frac{m^3}{2} - 4[/tex]
One-half the cube of m subtracted by 4 is [tex]0.5\sqrt[3]{m} -4[/tex]
Based on the information given, one-half the cube of m subtracted by 4 is expressed as:
[tex]0.5\sqrt[3]{m} -4[/tex]Note that the cube of m is expressed as [tex]\sqrt[3]{m}[/tex]The half of the cube of m will be given as [tex]0.5\sqrt[3]{m}[/tex]Subtracting 4 from the result will give the final expression as [tex]0.5\sqrt[3]{m} -4[/tex]

Square root 8 over three, (square root of 4)/2, and pi/3.
Step-by-step explanation:
First of all, square the radicals to make solving this easier. Squarer root 8 over three will become 8/9, and square root 4 over 2 will now become 4/4, which is 1. Pi/3 is greater than 1, so we can now order this from least to greatest. 8/9 is the least, 1 is the second greatest value, and pi/3 is the greatest value.

81*9 = 729, add in decimal and that's 72.9
Cross-multiplication:
90 100
? 81
This is read as 90 to 100, (as a ratio) so how many to 81? To solve, cross-multiply - 81*90=7290, then divide by 100 to get 72.9.
