Lisa purchased a hat for $10, a purse for $20, and a book for $23. The sales tax rate was 7.2 percent. What was the total amount she paid?
Answer:
$56.82
Step-by-step explanation:
The sum of all the stuff she bought is 10+20+23, so 53.
Now you need to find the tax, so you multiply 53 x 7.2%, and to change a % to a number you move the decimal place two to the left, so you get .072
$53 x .072 = $3.816 sales tax
$53 for the stuff plus $3.816 tax = $56.816
and since money is only two decimal places and the 6 is higher than 5, you have to round up to the nearest penny, so $56.82!
Answer:
56.81$ she paid
Step-by-step explanation:

Mark made a business trip of 259.5 miles. He averaged 59 mph for the first part of the trip and 57 mph for the second part. If the trip took 4.5 hours, how long did he
travel at each rate?
Answer: He spends 1.5 hours on the first part of trip and 3 hours on the second part of trip
Step-by-step explanation:
Let x = the number of hours for first part
Let y = the number of hours for second part
Concept: speed × time = distance
----------------------------------------------------------------
x+y=4.5
59x+57y=259.5
-----
y=4.5-x
59x+57y=259.5
-----
59x+57(4.5-x)=259.5
59x+256.5-57x=259.5
2x+256.5=259.5
2x=3
x=1.5
4.5-1.5=3 hrs
When finding all the roots of polynomials, how do you find the possible rational zeros to know which numbers you plug back into the function to get the number you synthetically divide by?
Answer:
You would have to break the polynomial down into smaller binomials or monomials. Take x^2-6x-9 for instance. It would break down into (x+3)(x-3) through the a^2+2ab+b^2 formula. After that set the two nomials equal to zero and solve for x. After that, you would plug back in x to see whatever x works. You may more than two nomials after breaking it apart so keep that in mind.
Write the equation of the line with slope = -3 and passes through (2,7)
Answer:
Step-by-step explanation:
y - 7 = -3(x - 2)
y - 7 = -3x + 6
y = -3x + 13
Evaluate the expression when a=-7. a^2+4a-2
Plug in the value to solve the expression.
[tex](-7)^2+4(-7)-2[/tex]
[tex]49-28-2[/tex]
[tex]19[/tex]
Hope this helps.
頑張って!
Hey there!
a^2 + 4a - 2
= -7^2 + 4(-7) - 2
= -49 - 28 - 2
= -77 - 2
= -79
Therefore, your answer is: -79
Therefore, your answer is: -79

Answer : The equation for 'h' is [tex]h=\frac{2A}{b}[/tex]
Step-by-step explanation :
The given equation is:
[tex]A=\frac{1}{2}bh[/tex]
Now we have to determine the equation for 'h'.
[tex]A=\frac{1}{2}bh[/tex]
Multiplying the equation by 2.
[tex]2\times A=2\times \frac{1}{2}\times bh[/tex]
on simplifying, we get:
[tex]2\times A=bh[/tex]
Dividing the equation by 'b'.
[tex]\frac{2\times A}{b}=\frac{bh}{b}[/tex]
[tex]\frac{2\times A}{b}=h[/tex]
or,
[tex]h=\frac{2A}{b}[/tex]
Therefore, the equation for 'h' is [tex]h=\frac{2A}{b}[/tex]
Answer: B
Step-by-step explanation:
Find the slope of the given line, if it is defined. 2x + 1 = 0
Given :
A line 2x + 1 =0 .
To Find :
The slope of the given line .
Solution :
We know , slope of line is given by the tangent of the angle between the x-axis and the line .
Now, for line 2x + 1 =0 i.e [tex]x=\dfrac{-1}{2}[/tex] .
The line is perpendicular to x-axis and cuts the x-axis at [tex]\dfrac{-1}{2}[/tex] .
Therefore , the angle between the line and x-axis is [tex]90^o[/tex] .
So , slope [tex]m=\tan\ 90^o[/tex] i.e undefined .
Therefore , the slope of given line is not defined .
Hence , this is the required solution .

What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.
WE have been given that 67.9 is ten times as much as unknown number;
Let the unknown number be z;
Z x 10 = 67.9
Now divide by 10 on both sides, we get;
Z = 67.9/10
Z = 6.79
Therefore,
6.79 x 10 = 67.9
Hence, the unknown number z would be 6.79

Rewrite the following expression as a single logarithm: log7(x2+5x−14)−log7(x+7)
Answer:
log7(x-2)
Step-by-step explanation:
Use of property: log(ab) = log(a) + log(b)
log7(x²+5x−14)−log7(x+7) = log7(x+7)(x-2) - log7(x+7) =log7(x+7) + log7(x-2) - log7(x+7) = log7(x-2)Simplify 0.5x-2y > 3
I will assume you want it in the form of y>mx+b
0.5x-2y>3
0.5x-3>2y
0.25x-1.5>y
Answer:
[tex]x>4y+6[/tex]
Step-by-step explanation:
[tex]0.5x-2y>3[/tex]
First, we will have to add 2 to both sides.
[tex]0.5x-2y+2y>3+2y[/tex]
This equals to
[tex]0.5x>2y+3[/tex]
Now, we will make this into a fraction and divide. We will divide by 0.5.
[tex]\frac{0.5x}{0.5} >\frac{2y+3}{0.5}[/tex]
Now that we divided, we got our answer!
[tex]x>4y+6[/tex]

Which number has an 8 that is 1/10 the value of the 8 in 78?
Step-by-step explanation:
Step one:
Firstly we need to determine the place value of 8 in the term 78
in the term, we have 7 tens and 8 units
hence the place value of 8 in 78 is the units
Step two:
Now 1/10 of 8 is given as
0.1*8= 0.8
According to the problem statement, we are expected to find a number that has an 8 that is the same as 0.8.
Say 5.8, 6.8, 9.8
we cannot say exactly, but any number that has an 8 that is one decimal away is an equivalent

Diego and Anya live 72 miles apart. They both meet at
their favorite restaurant, which is (16x – 3) miles from
Diego's house and (5x + 2) miles from Anya's house.
Diego argues that in a straight line distance, the restaurant
is halfway between his house and Anya's house. Is Diego
right? Justify your reasoning.
Answer:
The restaurant is not at half way
Step-by-step explanation:
Given
[tex]Total\ Distance = 72[/tex]
[tex]Diego = 16x - 3[/tex]
[tex]Anya = 5x + 2[/tex]
Required
Accept or reject Diego's claim
To do that, we need to determine the value of x by:
Diego + Anya =Total Distance
Substitute values for each parameter
[tex]16x - 3 + 5x + 2 = 72[/tex]
Collect Like Terms
[tex]16x + 5x = 72 + 3 - 2[/tex]
[tex]21x = 73[/tex]
Divide both sides by 21
[tex]x = \frac{73}{21}[/tex]
Substitute the value of x in Diego and Anya's distance
[tex]Diego = 16x - 3[/tex]
[tex]Diego = 16 * \frac{73}{21} - 3[/tex]
[tex]Diego = \frac{1168}{21} - 3[/tex]
[tex]Diego = \frac{1168 - 63}{21}[/tex]
[tex]Diego = \frac{1105}{21}[/tex]
[tex]Diego = 52\frac{13}{21}[/tex]
[tex]Anya = 5x + 2[/tex]
[tex]Anya = 5 * \frac{73}{21} + 2[/tex]
[tex]Anya = \frac{365}{21} + 2[/tex]
[tex]Anya = \frac{365 + 42}{21}[/tex]
[tex]Anya = \frac{407}{21}[/tex]
[tex]Anya = 19\frac{8}{21}[/tex]
Since, both distances are not equal,
Then Diego's claim is false and incorrect

A research team aboard an underwater research vessel descends 1,500 feet beneath the surface of the water. They then rise 525 feet and descend again 350 feet. Where are they currently located?
Answer:
-1,325 ft below sea level
Step-by-step explanation:
0(surface level) - 1,500 = -1,500
-1,500 + 525 = -975
-975 - 350 = -1,325
Answer:
they are currently at -1325 ft.
Step-by-step explanation:
first yo go up or in other words you subtract 525 to 1500 which gives you 973 then they descend 350 so they are going back down so you add 350 onto 975
