Write the following comparison as a ratio reduced to lowest terms. 36 nickels to 20 dimes
Answer:
0.9
Step-by-step explanation:
i) 1 nickel is equal to 5 cents
ii) 36 nickels will equal to = 36 × 5 = 180 cents
iii) 1 dime is equal to 10 cents
iv) 20 dimes will equal to = 20 × 10 = 200 cents
v) the ratio of 36 nickels to 20 dimes will equal to
= 36 nickels ÷ 20 dimes
= 180 cents ÷ 200 cents
= [tex]\frac{9}{10}[/tex]
= 0.9
To express the comparison of 36 nickels to 20 dimes as a ratio in lowest terms, calculate the value of nickels and dimes in pennies, then simplify the ratio. By converting to pennies and reducing, the ratio of 36 nickels to 20 dimes is 9:10.
Explanation:The question asks to write the comparison of 36 nickels to 20 dimes as a ratio reduced to lowest terms. To compare the value of nickels and dimes, we must know their value in pennies, the smallest unit of US currency. Since 1 nickel is worth 5 pennies and 1 dime is worth 10 pennies, we can express 36 nickels and 20 dimes in terms of pennies.
36 nickels = 36 x 5 pennies = 180 pennies
20 dimes = 20 x 10 pennies = 200 pennies
Now, we write the comparison as a ratio:
180 pennies : 200 pennies
Next, we reduce this ratio to lowest terms by dividing both numbers by their greatest common divisor, which is 20 in this case:
180 ÷ 20 : 200 ÷ 20
9 : 10
Therefore, the ratio of 36 nickels to 20 dimes reduced to lowest terms is 9:10.
At the yard sale,3\4 of items for sale were toys and 5\6 of the items for sale were books Were there more toys of books for sale explain
Answer:
No, the books had more sales by 5/6 being bigger (Greater Than) than 3/4.
By converting both fractions to have a common denominator of 12, it becomes clear that there were more books than toys for sale, as 10/12 (books) is greater than 9/12 (toys).
To determine whether there were more toys or books for sale, we need to compare the fractions ⅓ (representing toys) and ⅗ (representing books). To compare these fractions, they must have a common denominator. The least common denominator for 4 and 6 is 12. Converting both fractions to have the denominator of 12, you would get:
Toys: ⅓ = 3/4 = 9/12Books: ⅗ = 5/6 = 10/12When comparing 9/12 (toys) to 10/12 (books), it is clear that there were more books than toys for sale since 10/12 is greater than 9/12.

Step-by-step explanation:
Will ran the diagonal distance across a square field measuring 40 yards on each side. James ran the diagonal distance across a rectangular field with a length of 25 yards and a width of 35 yards. Will ran a longer distance. How much longer did he run?
Step-by-step explanation:
Given Will ran the diagonal distance across a square field measuring 40 yards each sides .
∴The distance covered by Will was =[tex]\sqrt{40^{2}+40^2 }[/tex] yards
= [tex]40\sqrt{2}[/tex] yards=56.56 yards
Again James ran diagonal distance across a rectangle field with a length of 25 yards and a width of 35 yards.
So,distance covered by James was =[tex]\sqrt{25^2+35^2}[/tex] yards
=[tex]5\sqrt{74}[/tex] yards = 43.01 yards
∴Will ran longer distance.
∴Will ran 13.55 yards more than James.
To calculate the longer distance Will ran compared to James, find the diagonal distances each ran. Will ran approximately 13.56 yards longer.
To determine how much longer Will ran compared to James, we need to calculate the diagonal distances for each run.
For the square field, diagonal = 40√2 ≈ 56.57 yards.The diagonal for the rectangular field = √(25² + 35²) = √(625 + 1225) = √1850 ≈ 43.01 yards.Will ran 56.57 - 43.01 ≈ 13.56 yards longer than James. Thus, Will ran around 13.56 yards longer than James, as determined by subtracting the diagonal of the rectangular field from that of the square field. This calculation offers a quantitative measure of the difference in running distances, providing insight into their comparative performances.
3(x-4)+5x=4x+4(x-3) is this conditional
The given equation is not the conditional equation.
Step-by-step explanation:
A conditional equation is true only certain values of the numbers present in it.
for example x + 3 = 9 is true only, if x = 6
3x - 5 = 10 is true only, if x = 5
The given equation is an Identity equation in which both sides of the equation is equal.
3(x - 4) + 5x = 4x + 4(x - 3)
3x - 12 + 5x = 4x + 4x - 12

3. You can ride your bike 1/5 of a mile per minute. If it takes you 3 1/3 minutes to get
to your friend's house, how many miles away does your friend live?
Answer:
(1/5)(10/3) = 10/15 = 2/3 mile
The friend lives [tex]$\frac{2}{5}$[/tex] of a mile away.
To solve this problem, we need to calculate the total distance based on the speed at which the bike is ridden and the time it takes to reach the friend's house.
First, we determine the speed at which the bike is ridden, which is given as [tex]$\frac{1}{5}$[/tex] of a mile per minute.
Next, we calculate the time it takes to reach the friend's house, which is [tex]$3\frac{1}{3}$[/tex] minutes. To work with this mixed number easily, we convert it to an improper fraction. [tex]$3\frac{1}{3}$[/tex] minutes is the same as [tex]$\frac{10}{3}$[/tex] minutes because [tex]$3\frac{1}{3} = 3 + \frac{1}{3} = \frac{9}{3} + \frac{1}{3} = \frac{10}{3}$[/tex].
Now, we can find the total distance by multiplying the speed by the time:
[tex]\[ \text{Distance} = \text{Speed} \times \text{Time} \][/tex]
[tex]\[ \text{Distance} = \frac{1}{5} \text{ mile/minute} \times \frac{10}{3} \text{ minutes} \][/tex]
When we multiply these two fractions, we multiply the numerators together and the denominators together:
[tex]\[ \text{Distance} = \frac{1}{5} \times \frac{10}{3} \][/tex]
[tex]\[ \text{Distance} = \frac{1 \times 10}{5 \times 3} \][/tex]
[tex]\[ \text{Distance} = \frac{10}{15} \][/tex]
We can simplify this fraction by dividing both the numerator and the denominator by their greatest common divisor, which is 5:
[tex]\[ \text{Distance} = \frac{10 \div 5}{15 \div 5} \][/tex]
[tex]\[ \text{Distance} = \frac{2}{3} \][/tex]
Therefore, the friend lives [tex]$\frac{2}{5}$[/tex] of a mile away.
Which equation represents the line with a slope of 5/6 that passes through the point (-2, 1)?
5x - 6y = -17
5x - 6y = -16
5x - 6y = 16
5x - 6y = 17
Answer:
Step-by-step explanation:
Slope m = 5/6
The points (-2,1)
So; y1 = 1 and x1 = -2
The equation is y - y1 = m(x - x1)
y - 1 = 5/6(x + 2)
Multiply each term by 6
6y - 6 = 5(x + 2)
6y - 6 = 5x + 10
6y = 5x + 10 + 6
6y = 5x + 16
- 5x + 6y = 16
Multiplying by minus
5x - 6y = -16
Answer:
5x - 6y = -16
Step-by-step explanation:
5/6 = (y - 1)/(x - 2)
cross multiplying,
5x + 10 = 6y - 6
5x - 6y = -16
simplify the expression 2(x-6)+2(8)
Answer:
2x+4
Step-by-step explanation:
Distribute:
=(2)(x)+(2)(−6)+(2)(8)
=2x+−12+16
Combine Like Terms:
=2x+−12+16
=(2x)+(−12+16)
=2x+4
Final answer:
The simplified expression of 2(x-6)+2(8) is 2x + 4 after distributing the 2 and combining like terms.
Explanation:
To simplify the expression 2(x-6)+2(8), you need to distribute the 2 into the parentheses and then combine like terms. Distributing the 2 into the first set of parentheses gives us 2x - 12.
For the second set, multiplying 2 by 8 gives us 16. So the expression becomes 2x - 12 + 16. Adding together the numerical terms (-12 + 16) gives us 2x + 4. Therefore, the simplified expression is 2x + 4.

How many gallons of 90% antifreeze must be mixed with 60 gallons of 10% antifreeze to get mixture that is 80% antifreeze?
420 gallons of 90% antifreeze must be mixed with 60 gallons of 10% antifreeze to get mixture that is 80% antifreeze
Solution:
Let "x" be the gallons of 90% antifreeze
The, final mixture would contain (x + 60) gallons
Then by given question, we can say,
"x" be the gallons of 90% antifreeze must be mixed with 60 gallons of 10% antifreeze to get 80 % of (x + 60) gallons
Thus we frame a equation as:
[tex]x \times 90 \% + 60 \times 10 \% = (x + 60) \times 80 \%[/tex]
Solve the above equation for "x"
[tex]x \times \frac{90}{100} + 60 \times \frac{10}{100} = (x + 60) \times \frac{80}{100}\\\\0.9x + 6 = (x+60) \times 0.8\\\\0.9x + 6 = 0.8x + 48\\\\\text{Combine the like terms }\\\\0.9x - 0.8x = 48 - 6\\\\0.1x = 42\\\\x = \frac{42}{0.1} = 420[/tex]
Thus, 420 gallons of 90% antifreeze is used

.. Find the unit rate of the
situation below:
It costs $21.25 to buy lunch
for 5 days.
The unit rate is $4.25 per day for lunch.
To find the unit rate of how much it costs to buy lunch for one day, we divide the total cost by the number of days. In this case, the total cost is $21.25 for 5 days of lunch.
Here's the calculation to find the unit rate:
Divide the total cost by the number of days: $21.25 / 5 = $4.25
Hence, the unit rate is $4.25 per day for lunch.
Devin was born in Minnesota, but now he lives in lowa, close to where lowa, Wisconsin, and Illinois meet. He works in Wisconsin, but he buys all of his
clothes at a store in Illinois. If the sales tax rates for the four states are as
shown in the following table, which sales tax rate does Devin pay on the
clothes he buys?
State Sales tax
Illinois 6.25%
lowa 6%
Minnesota 6.875%
Wisconsin 5%
A. 5%
B. 6%
C. 6.875%
D6.25%
Devin buys his clothes in Illinois, so he would pay the sales tax rate of Illinois, which is 6.25%. Therefore, the correct answer is D. 6.25%.
Certainly! Devin buys his clothes in Illinois, where the sales tax rate is 6.25%. This means that for every dollar he spends on clothes, he pays an additional 6.25 cents as tax.
To calculate how much tax Devin pays on a $100 purchase, you can use the formula:
[tex]\[ \text{Tax Amount} = \text{Purchase Amount} \times \text{Tax Rate} \][/tex]
Substitute the values:
[tex]\[ \text{Tax Amount} = \$100 \times 0.0625 \][/tex]
[tex]\[ \text{Tax Amount} = \$6.25 \][/tex]
So, if Devin buys clothes worth $100 in Illinois, he would pay $6.25 as sales tax, which corresponds to the 6.25% tax rate of Illinois.
Owen and Bella shared a granola bar. Bella ate 1/4 of the granola bar. Owen ate 1/3 of the bar. How much of the granola bar did Owen and Bella leave uneaten?
A. 5/7
B . 1/24
C . 3/8
D . 5/12
I will mark brainlist if correct :)))
Answer:
D. 5/12
Step-by-step explanation:
I will have a picture attached to the answer. But I will explain it overall.
So let's start off with what information we have: Bella ate 1/4 of the bar and Owen at 1/3 of the same bar.
So how much overall was gone by the two? Well, in this part we will add the two fractions.
1/3 + 1/4 =?
Yet, here's the thing, these two fractions have different denominators. What we have to do is make them the same denominator. In order to do so we have to find the Least Common Multiple of the denominators.
So with that in mind...
Multiples of 3: 3,6,9,12,15,18,21,...
Multiples of 4: 4,8,12,16,20,24...
Do you see a number that 3 and 4 have? Welp, I do! It's 12! So here is what going to happen! We will set up the problem like this!
1/3 times ? equal x/12
+ 1/4 times ? equal x/12
Now you may be wondering what is the question mark for and what is "x"? Here's the thing, since we know the new fraction we have to figure out what times the original denominators equal the new denominator! So with 1/3, what or how do we make the 3 into 12? Well 3 times 4 equals 12! So that is ?. The ? will be 4/4. Because whatever you do to the bottom you do to the top.
1/3 times 4/4 equals 4/12
Now we do the same thing for the 1/4 fraction. Except the question mark will be 3/3 since 4 times 3 equals 12
1/4 times 3/3 equals 3/12
Okay, now we have 4/12 + 3/12= x/12. Let's add the fractions. 4+3=7 and the 12 of the denominator will stay the same. So 1/3+1/4 or 4/12+3/12 now equals 7/12.
The real question is what is LEFTOVER of the granola bar? So we have what was devoured of the bar, so now we can subtract the part that was gone with the whole bar. So...
1 whole bar equals 12/12
- the devoured part equals 7/12
left over or untouched = 5/12
So the answer to the question is D. 5/12
I hope this helps you, I'm sorry this took me a long time, I again do have a picture attached to the answer. If you need any help or have a question please don't be afraid to ask! Have a good day!
Answer: option D.
The total amount of the granola bar is = 1.
Given that they have eaten 1/4 and 1/3 of the bar.
So they have eaten a total of [tex]\frac{1}{4}+\frac{1}{3}=\frac{7}{12}[/tex] of the bar.
So the remaining amount is = [tex]1-\frac{7}{12}=\frac{12}{12}-\frac{7}{12}=\frac{5}{12}[/tex].
So option D is right.

Answer:
Part 1) The sum of the two angles equals 70 degrees
Part 2) The complementary angle is 19 degrees and the supplementary angle is 109 degrees
Step-by-step explanation:
Part 1) we know that
The sum of the interior angles in any triangle must be equal to 180 degrees
so
In the triangle JKL
[tex]m\angle JKL+m\angle KLJ+m\angle LJK=180^o[/tex]
we have
[tex]m\angle JKL=110^o[/tex]
substitute
[tex]110^o+m\angle KLJ+m\angle LJK=180^o[/tex]
[tex]m\angle KLJ+m\angle LJK=180^o-110^o[/tex]
[tex]m\angle KLJ+m\angle LJK=70^o[/tex]
therefore
The sum of the two angles equals 70 degrees
Part 2) we know that
If two angles are complementary, then their sum is equal to 90 degrees
If two angles are supplementary, then their sum is equal to 180 degrees
step 1
Find the complementary
Let
c ----> the complementary angle
[tex]m\angle c+71^o=90^o[/tex]
[tex]m\angle c=90^o-71^o=19^o[/tex]
step 2
Find the supplementary
Let
s ----> the supplementary angle
step 1
Find the complementary
Let
c ----> the complementary angle
[tex]m\angle s+71^o=180^o[/tex]
[tex]m\angle s=180^o-71^o[/tex]
[tex]m\angle s=109^o[/tex]
therefore
The complementary angle is 19 degrees and the supplementary angle is 109 degrees

At winstead elementary school 10.2% of the 88 boys have blue eyes and 5.3% of the 75 girls have blue eyes. What percent of the school as a whole had blue eyed students
Answer: ≈ 8%
Step-by-step explanation:
Total number of students = total number of boys + total number of girls
Total number of students = 88 + 75
Total number of students = 163
10.2% of the boys have blue eyes , this means that 10.2% of 88 have blue eyes
[tex]\frac{10.2}{100}[/tex] x 88 = 8.976
Since we are dealing with humans , therefore , this means that 9 boys have blue eyes.
Also , 5.3% of the girls have blue eyes means that 5.3% of 75 have blue eyes. That is
[tex]\frac{5.3}{100}[/tex] x 75 = 3.975 , therefore : 4 girls have blue eyes.
In total , 13 students have blue eyes
Therefore , to calculate the % of students that have blue eyes , we have :
13/163 x 100 = 7.975460123
Therefore : ≈ 8% of the students have blue eyes

Please show the steps so I can learn too. Thank you!
Question 1:
For this case we must solve the following system of equations by the method of elimination:
[tex]8x-6y=-20\\-16x+17y=30[/tex]
We multiply the first equation by 2:
[tex]16x-12y = -40[/tex]
We have the equivalent system:
[tex]16x-12y = -40\\-16x + 17y = 30[/tex]
We add the equations:
[tex]5y = -10[/tex]
We divide between 5 on both sides of the equation:
[tex]y = - \frac {10} {5}\\y = -2[/tex]
We find the value of the variable "x":
[tex]8x-6 (-2) = - 20\\8x + 12 = -20\\8x = -20-12\\8x = -32[/tex]
We divide by 8 on both sides of the equation:
[tex]x = - \frac {32} {8}\\x = -4[/tex]
Thus, the solution of the system is:
[tex](x, y): (- 4, -2)[/tex]
Answer:
[tex](x, y): (- 4, -2)[/tex]
Question 2:
For this case we must solve the following system of equations by the method of elimination:
[tex]-4y-11x = 36\\20 = -10x-10y[/tex]
We multiply the first equation by 10:
[tex]-40y-110x = 360[/tex]
We multiply the second equation by -4:
[tex]40y + 40x = -80[/tex]
We have the equivalent system:
[tex]-40y-110x = 360\\40y + 40x = -80[/tex]
We add the equations:[tex]-70x = 280[/tex]
We divide by -70 on both sides of the equation:
[tex]x = \frac {280} {- 70}\\x = -4[/tex]
We find the value of the variable "y":
[tex]-4y-11 (-4) = 36\\-4y + 44 = 36\\-4y = 36-44\\-4y = -8[/tex]
We divide between -4 on both sides of the equation:
[tex]y = - \frac {8} {- 4}\\y = 2[/tex]
Thus, the solution of the system is:
[tex](x, y): (- 4,2)[/tex]
Answer:
[tex](x, y): (- 4,2)[/tex]
