Step-by-step explanation:
so, she spent 25-16.39 = $8.61 on the ribbon.
1 yard of the ribbon costs $0.21.
how many yards did she buy with that amount of money ?
well, as many times as 0.21 fits into 8.61 :
8.61 / 0.21 = 41
so, she bought 41 yards of ribbon.
I'm happy to help you today!
Answer:
41 yards is correct
Step-by-step explanation:
Step 1. The information we have is:
Originally Jane had $25 on her debit card.
She made a purchase of bulk ribbon for 21 cents per yard.
And after that she ended up with $16.39 on the card.
Step 2. Make an equation to describe the situation.
The equation that describes this situation is:
[tex]\tt 25-0.21y=16.39[/tex]
Where 25 is the initial amount and to that, we subtract 0.21y, where y is the number of yards that she bought of ribbon. And all of this has to be equal to the final amount of 16.39.
Step 3. Solve the equation for y:
To solve for y, we subtract 25 to both sides of the equation:
⇒ [tex]\tt-0.21y=16.39-25[/tex]
⇒ [tex]\tt -0.21y=-8.61[/tex]
Then, divide both sides of the equation by -0.21:
[tex]\tt y=\frac{-8.61}{-0.21}[/tex]
The result is:
[tex]\tt y=41[/tex]
The answer is 41 yards of ribbon.
Hope this helps you!Have an awesome day! :)[tex]-Nature-[/tex]

solve the fraction -2/5 + 1/8=
Answer:
-11/40
Step-by-step explanation:
-2/5+1/8=?
Turn the fractions into the same denominators:
-2/5 x 8/8= -16/40
1/8x 5/5= 5/40
-16/40+5/40=
now just add the numerators
-16+5= -11

A town with a population of 5,000 grows 3% per year. Find the population at the end of two years using the Growth and Decay method.
Answer:
5304 people
Step-by-step explanation:
So, we have a population of 5000 people and it grows 3% per year. This problem wants us to find how much it will grow to at the end of 2 years.
With this, we have values that follow:
The formula: f(t) = a(1 + r)^t
a = 5000
r = 0.03
t = 2
Plugging it the values in the formula,
f(2) = 5000(1 + 0.03)^2
= 5000(1.03)^2
= 5304.5
Since there can't be a half person, we will have to reduce it down to 5304
f(2) = 5304

Alice passes through four tra¢ c lights on her way to work, and each light is equally likely to be green or red, independent of the others. Suppose that each red light delays Alice by exactly two minutes. What is the variance of Aliceís commuting time?
Using the binomial distribution, it is found that the variance of Alice's commuting time is of 2 minutes squared.
For each light, there are only two possible outcomes, either it is red, or it is green. The lights are independent of others, hence the binomial distribution is used to solve this question.
What is the binomial probability distribution?It is the probability of exactly x successes on n repeated trials, with p probability of a success on each trial.
The variance of the binomial distribution is:
[tex]V(X) = np(1 - p)[/tex].
In this problem:
She passes through four lights, hence n = 4.The lights are equally as likely to be red or green, hence p = 0.5.The variance for the number of red lights is:
V(X) = 4(0.5)(0.5) = 1
Since each red light delays Alice by exactly two minutes, the variance of Alice's commuting time is of:
2 x 1 = 2 minutes squared.

Answer:
x° = 100°y° = 80°z° = 85°Step-by-step explanation:
The relations that you need to know to solve this are ...
vertical angles are congruentconsecutive interior angles are supplementary__
The angle marked x° and the one marked 100° are vertical angles, so have the same measure:
x° = 100°
__
The angle marked y° is supplementary to the one marked x°, so its value is ...
y° = 180° -100° = 80°
__
The two angles marked z° and (z+10)° are also supplementary, so ...
z° +z° +10° = 180°
2z° = 170°
z° = 85°

Mr. Chen must wear a dress shirt and a tie to work. Each day he picks
one of his 6 ties at random, Design a simulation that could be used to
model this situation
Answer:
54 kilometers per hour
step-by-step explanation:
according to rules:
1 km = 1000 meter
which means that 1 meter = 1/1000 km
1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]
which means that 1 second = 1/3600 hour
therefore, 1 kilometer/hour = (1/1000)/(1/3600)=3600/1000=18/5=3.6 kilometer/hour
thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.
15 meter/second= 15*3.6=54 kilometer/hour which is the required answer.

Answer:
William has 24 cans of fruit and 60 cans of vegetables that he will be putting into bags for a food drive.
Factor number 24 and 60:
Find the greatest common factor
Hence, the greatest number of bags William can make is 12.
Each of these bags will have cans of fruit and cans of vegetables.
If he made fewer bags, 6 bags, each of these bags will have cans of fruit and cans of vegetables.
If he made fewer bags, 4 bags, each of these bags will have cans of fruit and cans of vegetables.
If he made fewer bags, 3 bags, each of these bags will have cans of fruit and cans of vegetables.
If he made fewer bags, 2 bags, each of these bags will have cans of fruit and cans of vegetables.

if n = 11 and p = 5 what is the value of the expression 18 - n - 2 + p
Answer:
10
Step-by-step explanation:
If n = 11 and p = 5, we can just substitute the values in for n and p in the equation 18 - n - 2 + p.
The new equation would be 18 - 11 - 2 + 5.
Using PEMDAS, we get the answer of 10.
18 - 11 = 7
7 - 2 = 5
5 + 5 = 10

Please help me it’s math iready for a 7th grader
Answer:
m - 7.50 = 12.50
and
m = 7.50 + 12.50
Step-by-step explanation:
The best answers would be:
m - 7.50 = 12.50
and
m = 7.50 + 12.50
First of all, let's figure out what the question is asking us:
The question is asking us to find the amount of money on the gift card
It tells us to use "m" for "the amount of money on the gift card"
Now that we know the following, we can put together the equation
m = the amount of money on the gift card
$7.50 = cost of the book
$12.50 = amount remaining
Since he receives the gift card and then buys a book that costs $7.50, we are going to "have to subtract $7.50 from m". And we know that $12.50 is remaining, so we "make the equation equal to 12.50".
So, let's set up the equation:
m - 7.50 = 12.50
Now that we know the equation, we can solve for "m"
m - 7.50 = 12.50
Step 1: Add 7.50 to both sides.
m − 7.50 7.50 = 12.50 + 7.50
Step 2: Simplify
Answer: m = 20
Another way you can set up this equation is:
m = 7.50 + 12.50
Because we want to find "m", we set it equal to the equation. Since Salim bought a book for $7.50 and had $12.50 remaining, we want to find how much he had on the gift card that made him have $12.50 remaining when he bought the book. So, we have to add 7.50 and 12.50, to find how much is on the gift card.
So, the equation "m = 7.50 + 12.50", makes sense when solving for "m"
Hint: Once you have realized that the equation has Like Terms on the same side you must Combine the Like Terms by either adding them together or subtracting them.
Now that we know the equation, let's solve it
m = 7.50 + 12.50
Step 1: Combine like terms
m = (7.50 + 12.50)
m = 20
Since both equations equal $20 and both make sense, we can conclude that these are the best options.

Answer:
A = 56 in²
Step-by-step explanation:
the area (A) of a trapezoid is calculated as
A = [tex]\frac{1}{2}[/tex] h (b₁ + b₂ )
h is the perpendicular height between bases and b₁, b₂ the bases
here h = 7 , b₁ = 10 , b₂ = 6 , then
A = [tex]\frac{1}{2}[/tex] × 7 × (10 + 6) = 3.5 × 16 = 56 in²
