(-3.1-(-6.2))=3.1, but -1.55-3.1 is not 3.1, showing that that is not arithmetic. For the last one, 3-(-3)=6, 9-3=6, etc. proving that you add 6 every time and the sequence is therefore arithmetic.
what is the preimter and area of a rectangle that is 30 inchs long and 39 inchs wide
Answers
30 x 2 = 60
39 x 2 = 78
60 + 78 = 138
And never forget to label your units!
The perimeter of the rectangle is 138 inches.
To get the area, multiply the sides by each other.
30 x 39 = 1170
The area of the rectangle is 1170 inches^2, or 1170 inches squared.
Area is 1170 (30*39)

Rounded Total: $22
Exact Total: $21.77
B) The total on the register is reasonable because even with the rounded price at the end, it is only 23 cents off, which is good.
Answer and explanation:
Given : At the grocery store checkout, you watch at the register as it rings up your purchases and coupons.
The register gives your total bill as $21.77.
To find :
(a) Round each price and coupon to the nearest dollar and then estimate the total amount of the bill.
The prices are as follows:
$2.95 estimated to $3 as (9>5)
$1.19 estimated to $1 as (1<5)
$4.61 estimated to $5 as (6>5)
$1.74 estimated to $2 as (7>5)
$3.04 estimated to $3 as (0<5)
$8.83 estimated to $9 as (8>5)
$1.16 estimated to $1 as (1<5)
− $0.75 (coupon) estimated to -$1 as (7>5)
− $1.00 (coupon) estimated to -$1 as (0<5)
The total amount bill is $3+$1+$5+$2+$3+$9+$1-$1-$1=$22.
So, Estimated total amount of the bill is $22.
(b) Using your estimate, determine whether the total on the register is reasonable. Justify your answer.
The register gives your total bill as $21.77.
The total on the register is reasonable because even with the rounded price at the end the price became same which is reasonable.
As 21.77 estimated to 22 as (7>5).
Peaches are being sold for $2 per pound. If x represents the number of pounds of peaches bought and yrepresents the total cost of the peaches, which best describes the values of x and y?
Answers
2) y = total cost of the peaches
3) formula would be: y = $2x
but i don't understand what you'd want to know...
Let
x----------> represents the number of pounds of peaches bought
y----------> represents the total cost of the peaches
we know that
Peaches are being sold for [tex]2\frac{\$}{pound}[/tex]
so
the equation that best describes the values of x and y is equal to
[tex]y=2x[/tex] or [tex]x=y/2[/tex]
The relationship between the two variables, x, and y, represent a direct variation
therefore
the answer is
[tex]y=2x[/tex] or [tex]x=y/2[/tex]
during a football game, kevin gained 5 yards on the first play. then he lost 7 yards on the second play. how many yard does kevin need on the next play to get the team back to where when they started? show your work.
Answers
So to get back to 5 you need to first make the number positive so you will need to gain 2 points first making it equal . So then you need to get 5 more points to make it 5 .
So to sum it up I made the number positive when doing that your making it zero so then all you have to do is add the option Reginald number back in so here's my work
5-7= -2 -2 + 2= 0 0+5=5

A physicist working in a large laboratory has found that light particles traveling in a particle accelerator increase velocity in a manner that can be described by the linear function −4x + 3y = 9, where x is time and y is velocity in kilometers per hour. Use this function to determine when a certain particle will reach 50km/hr.
The particle will reach 50km/hr when x =
.
Answers
Answer:
x = 35.25 hr
Step-by-step explanation:
The velocity model is given by −4x + 3y = 9, where x is time and y is velocity in kilometers per hour.
Solve the equation for x
Add 4x to both sides of the equation
[tex]3y=4x+9[/tex]
Subtract 9 to both sides
[tex]3y-9=4x[/tex]
Divide both sides by 4
[tex]x=\frac{3}{4}y-\frac{9}{4}[/tex]
Now, we have to find x for y = 50
Replace y with 50
[tex]x=\frac{3}{4}\cdot50-\frac{9}{4}\\\\x=\frac{75}{2}-\frac{9}{4}\\\\x=\frac{141}{4}\\\\x=35.25[/tex]
Therefore, the particle will reach 50 km/hr when x = 35.25 hr
If y=-7 when x=-21, what is the value of x when y=9
Answers
So then when y=9, 9=x-21.
Solve for x.
x=9+21
x=30
If y = -7 when x = -21, then y = (1/3)x, and (1/3) is the constant of proportion.
A similar truth is that x = 3(y), as -21 = 3(-7)
So, if y=9, x = 3(9) = 27

According to the school survey, 12% of the students at Rockwood Junior High School speak Spanish. There are 36 students at the school who speak Spanish. How many students were surveyed?
Answers
36=(0.12)n
n=300
300 students were surveyed.
That's the way I answer in my country but I'm not sure about this solution is correct in your school or not.
Answer:
300 students were surveyed.
Step-by-step explanation:
We are given the following information in the question:
Percentage of students at Rockwood Junior High School who speak Spanish = 12%
Number of students at Rockwood Junior High School who speak Spanish = 36
We have to find the total number of students who surveyed:
Formula:
Let x be the total number of students who were surveyed.
[tex]12\% \text{ of }x = 36\\\\\displaystyle\frac{12}{100}\times x = 36\\\\x = \frac{36\times 100}{12}\\\\x = 300[/tex]
Thus, 300 students were surveyed.

A movie theater has 24 screens. The ratio of action films to other film is 1:2 in the summer. How many action films are shown?
Answers
Answer:
8 action films being shown
Step-by-step explanation:
Great question, it is always good to ask away and get rid of any doubts that you may be having.
Based on this question we can see that the movie theater has 1 action movie for every 2 other type of movies. We can add these two numbers together and divide by 24 to find out how many action movies are playing compared to the other types of movies.
[tex]1 + 2 = 3[/tex]
[tex]24 / 3 = 8[/tex]
8 action movies : 16 other type of movies
As we can see from the adjusted ratio above, there are 8 action films being shown

Carlos purchased an antique chair for $15 he later so this year for $27 to an antique dealer what was the percent markup of the chair
Answers
Answer: The required percent markup is 80%.
Step-by-step explanation: Given that Carlos purchased an antique chair for $15 and later he sold it this year for $27 to an antique dealer.
We are to find the percent markup of the chair.
The markup price of the chair is given by
[tex]m_p=\$(27-15)=\$12.[/tex]
Since Carlos purchased the chair for $15, so the markup percent is given by
[tex]\dfrac{m_p}{15}\times100\%\\\\\\=\dfrac{12}{15}\times100\%\\\\\\=\dfrac{4}{5}\times100\%\\\\=80\%.[/tex]
Thus, the required percent markup is 80%.
