Answer:
Step-by-step explanation:
Figure Skates:
f(x)=1.50(3) + 2.00
f(x)=4.5 + 2.00
f(x)= 6.5
Hockey Skates:
f(x)=2.00(3) + 1.50
f(x)=6.00 + 1.50
f(x)= 7.50
Figure skates are $1 cheaper than hockey skates.
A prepaid phone card has a balance of $22.40 remaining. If calls are $0.035 per minute, which equation represents the number of minutes, m, you may talk using the card?
Answer:
The equation that represents the number of minutes that Imay talk using the card is [tex]m =28.571\cdot C[/tex].
Step-by-step explanation:
From statement we know that balance ([tex]C[/tex]), measured in US dollars, is directly proportional to remaining call time ([tex]m[/tex]), measured in minutes. That is:
[tex]C \propto m[/tex]
[tex]C = k\cdot m[/tex] (Eq. 1)
Where [tex]k[/tex] is the proportionality ratio, measured in US dollars per minute.
If we know that [tex]k = 0.035\,\frac{USD}{min}[/tex], then the equation is:
[tex]C = 0.035\cdot m[/tex]
Now we clear remaining call time within equation:
[tex]m =28.571\cdot C[/tex]
The equation that represents the number of minutes that Imay talk using the card is [tex]m =28.571\cdot C[/tex].
1/2(10k - 16) + 11 = -2 solve for k and show your work in rows
Answer:
k= -1
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
(10k-16)+11= -2
[tex](\frac{1}{2} ) (10k)+(\frac{1}{2} )(-16)+11 = -2[/tex]
(5k)+(-8+11)= -2
5k+ 3= -2
Step 2: Subtract 3 from both sides.
5k+3−3=−2−3
5k=−5
Step 3: Divide both sides by 5.
[tex]\frac{5k}{5} = \frac{-5}{5}[/tex]
k= -1
Anthony has 260 cars and sells them at a rate of 5 cards a day. Ben has 100 cards and buys them at a rate of 3 cards per day. After how many days will they have the same number of cards
Answer:
After 20 days, they will have the same number of cards
Step-by-step explanation:
Given;
number of cards with Anthony, = 260 cards
rate of his sale = 5 cards/day
number of cards with Ben, = 100 cards
rate of his purchase, = 3 cards/day
let the number of days when they will have the same number of card = n
set up the linear equation, consider sale as subtraction from the initial value and also consider purchase as an addition to the initial value.
260 - 5n = 100 + 3n
260 -100 = 3n + 5n
160 = 8n
n = 160 / 8
n = 20 days
Therefore, after 20 days, they will have the same number of cards
Prenell is filling his car with gasoline. Regular unleaded gas costs $1.89 per gallon. Which two equations show the proportional relationship between the total cost, c, and the price per gallon, p, of gasoline?
(more than one answer)
a. p=1.89c
b. c=1.89/p
c. pc=1.89
d. c=1.89p
e. p/c=1.89
f. c/p=1.89
Answer:
Step-by-step explanation:
For all Plato users.
c = 1.89p and c/p = 1.89 these two equation shows the proportional relationship between the cost c, and price p.
What is Proportionality Constant?Two sequences of numbers, often experimental data, are proportional or directly proportional if their corresponding elements have a constant ratio, which is called the coefficient of proportionality or proportionality constant.
Here, Total cost = $c
Price per gallon = $ 1.89
Total cost = Price per gallon X total units
c = 1.89 X p
c = 1.89p
or, c/p = 1.89
Thus, c = 1.89p and c/p = 1.89 these two equation shows the proportional relationship between the cost c, and price p.

Ms. Smith bought 30 boxes of pencils at the beginning of the year. Each box costs $2.15 including tax. 6/15 of the boxes she bought have been used. How much money did she spend on the remaining boxes?
Answer:
She spent $38.7 on the remaining boxes.
Step-by-step explanation:
total number of boxes of pencil bought by Ms. Smith, = 30 boxes
cost of each box = $2.15
fraction of boxes of pencil used = 6 / 15
number of boxes of pencil used = [tex]\frac{6}{15} *30 \ boxes = 12 \ boxes[/tex]
number of boxes of pencil remaining = 30 boxes - 12 boxes = 18 boxes
Cost of the 18 boxes remaining = 18 x $2.15
= $38.7
Therefore, she spent $38.7 on the remaining boxes.

Some spiders can spin a web at 3 cm per second. Convert this rate to meters per minute. (100 cm = 1 m)
Answer:
1.8m per minute
Step-by-step explanation:
Answer:
[tex]\frac{1.8 \ m}{1 \ min}[/tex] ; (1.8 meters per minute)
Step-by-step explanation:
Use dimensional analysis to solve this problem.
The proper units of conversion are given in parentheses on this question: 100 cm = 1 m.
Start with the given value, 3 centimeters/1 second.
[tex]\frac{3 \ cm}{1\ sec}[/tex]Convert this rate to meters/minute by multiplying 3 cm/1 sec by 1 m/100 cm.
[tex]\frac{3 \ cm}{1 \ sec} * \frac{1 \ m}{100 \ cm}[/tex]The top and bottom units should cancel out, so that's how you know to put the cm units on the bottom to cancel out with the 3 cm on the top.
Multiply the fractions together. The "cm" units cancel out.
[tex]\frac{3\ m}{100 \ sec}[/tex]Now you want to make the bottom units = minutes. There are 60 seconds in 1 minute, so you can use [tex]\frac{60 \ sec}{1 \ min}[/tex] to multiply with [tex]\frac{3\ m}{100 \ sec}[/tex].
[tex]\frac{3\ m}{100 \ sec} * \frac{60 \ sec}{1 \ min}[/tex]The "seconds" unit cancels out, so you are left with meters on the top and minutes on the bottom. Multiply the fractions together.
[tex]\frac{180 \ m}{100 \ min}[/tex]We want the rate to be meters per minute (1), so completely simplify this fraction and divide the fraction by (100/100), so the denominator is 1 min.
[tex]\frac{180 \ m}{100 \ min} \div \frac{100}{100}= \frac{1.8 \ m}{1 \ min}[/tex]If m7 is 100 find m3
Answer:
m3 is 100 degrees
Step-by-step explanation:
In this case, angle 7 is congruent to angle 5 because both their angles are located on the same place in different lines. Another rule you need to know is that angles across from each other are equal. So, if angle 5 is 100 degrees, then angle 3 is also 100 degrees because they are across from each other.

Hayley is buying herbs. She wants to buy 5/6 ounce of basil. The scale she is using to weigh the basil displays the weight as a decimal. How will she know when the display on the scale is correct to the tenths place? Explain your reasoning.
Answer:
0.8 ounces
Step-by-step explanation:
Given that:
Ounce of basil Hayley wishes to purchase = 5/6 ounces
Since the scale is displaying as decimal, then the fraction of basil to be purchased will be could be converted to decimal;
5/6 = 0.83333
To the nearest tenth ;
5/6 = 0.8 ounces
Once the display on the scale shows 0.8, then it is equivalent to 5/6 ounces of basil.

a) 2x -1.5 = 2x - 1.5
-
b) 2v + 4 = -1
Answer:
a) all real numbers
b) v = -2.5
Step-by-step explanation:
a) 2x - 1.5 = 2x - 1.5
subtract 2x from both sides of the equation
2x - 1.5 - 2x = 2x - 1.5 - 2x
1.5 = 1.5
since 1.5 will always equal 1.5 regardless of what x is,
the solution is all real numbers
b) 2v + 4 = -1
subtract 4 from both sides of the equation
2v + 4 - 4 = - 1 - 4
2v = -5
divide both sides of the equation by 2
2v/2 = -5/2
v = -2.5
