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.

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

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

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

Answer:
-25x + 50y = 19
Step-by-step explanation: So sorry if I'm wrong
Answer:
x=3
y=2
Step-by-step explanation:
you can either use substitution or elimination method
I find substitution method better
substitute x with 3 and in this method u use one of the equation
10(2)-20y=-10
20-20y=-10=2
y=2
now use y=2 with the same equation
10x-40=-10=30
10x=30
x=3
therefore
x=3
y=2
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.

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].

The price of a baseball glove is $8 more than half the price of spikes. The glove costs $54. Solve the equation 5/2+ 8 = 54 to find out how much the spikes cost.
Answer:

1/2 + 8 = 54
subtract 8 from both sides: 1/2 = 46
divide 46 by 1/2: 23
check your answer: 23 * 2 + 8= 54

Step-by-step explanation:
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]The value of group therapy for the treatment of mental health disorders is that an individual can __________.
