the ratio of the number of oranges to apples to bananas is 8:5:2. if there are 120 fruits in total, how many bananas are there
Answer:
Step-by-step explanation:
To find the number of bananas, we need to determine the proportion of bananas in the total number of fruits based on the given ratio.
Let's assume that the ratio of oranges, apples, and bananas can be represented by 8x, 5x, and 2x, respectively, where x is a common multiplier.
The sum of the parts in the ratio is 8x + 5x + 2x = 15x.
We know that the total number of fruits is 120. Therefore, we can set up the following equation:
15x = 120
To solve for x, we divide both sides of the equation by 15:
x = 120 / 15
x = 8
Now that we know the value of x, we can find the number of bananas by multiplying it by the corresponding part of the ratio:
Number of bananas = 2x = 2 * 8 = 16
So, there are 16 bananas in total.
We can add all the parts to the ratio and get 15. Out of 15 parts, 2 are bananas. Now we can calculate how many fruits are in one part. One fifteenth of 120 is 8, so there are 8 fruits in one part. 2 parts are bananas, so multiplying 8 with 2 gives us our answer, 16.

Solve for x.
4 (x − 20) = −20
Enter your answer in the box.
x = ?
Answer:
the solution for x is 15.
Step-by-step explanation:
First, we can simplify the equation by dividing both sides by 4:
x - 20 = -5
Then we can solve for x by adding 20 to both sides of the equation:
x - 20 + 20 = -5 + 20

1. A straight fence is constructed from posts 6 inches wide and separated by lengths of chain 5 feet long. A certain fence begins and ends with a post. If there are 7 posts, what is the total length of the fence?
Answer:
72
Step-by-step explanation:
First, we will multiply the number of posts (7) by the posts' width (6) to get 42.
Since there is a chain between each post, there are 6 chains.
Multiplying the number of chains (6) by the chains' length (5), we get 30.
The question asks us to find the total length of the fence, so we add 42 and 30 and get 72.

Answer:
\(\huge\boxed{l = \frac{p}{2} - 2}\)
Step-by-step explanation:
If we have the equation \(p=2(l+w)\) and we want to solve for l, our goal is to isolate l on one side of the equation.
We can do this by reversing the equation - looking at what is stopping l from being alone on one side.
First lets divide both sides by 2:
\(p \div 2 = 2(l+w) \div 2\\\frac{p}{2}=l+w\)
Now we can subtract w from both sides.
\(\frac{p}{2} - w = l+w-w\\\\\frac{p}{2} - w = l\)

$26, S37. S48, $57, $68, $75
PLS HELP.
Answer: your answer is 75 7 people is 10 dollars
Step-by-step explanation:
If a movie ticket costs S4 for children, $6 for senior citizens, and $10 for all others. If 7 people buy tickets, then possible total sales is $48.
What is equation?Two or more equations with an equal sign is called as Equation.
Given that
A movie ticket costs S4 for children
For senior citizens it costs $6
and $10 for all others.
If 7 people buy tickets
Then the possible total sale is $48.
3 Children tickets, 1 senior citizens and 3 other people.
3(4)+6+3(10)
Three times of four plus six plus three times of ten
Three times of four is twelve and three times of ten is thirty
So 12+6+30

Answer:
\(13.5 m^{2}\)
Step-by-step explanation:
area = length × width
= 15m × 9/10m
= 15m × 0.9m
= \(13.5 m^{2}\)
Answer:
\(\Huge \fbox{Area = 13.5 m^{2}$}\)
Step-by-step explanation:
To find the area of the baseboard, we need to multiply the length by the width:
The length of the baseboard is given as 15 metres. The width of the baseboard is given as \(\frac{9}{10}\) metre.To multiply these values, we can convert the width to a decimal by dividing the numerator (9) by the denominator (10):
\(\frac{9}{10} = 0.9\)Now we can multiply the length and width:
\(\text{Area = Length $\times$ Width}\)\(\text{Area = 15 m $\times$ 0.9 m}\)\(\text{Area = 13.5 m^{2}$}\)Therefore, the area of the baseboard is 13.5 m².

This shows an equation.
5(4 + 2x) + 5 = 3(2x + 5) + 4x + 10
How many solutions does this equation have?
check if the resulting expression is always true, sometimes true, or never true for all values of x.
We can simplify the given equation as follows:
5(4 + 2x) + 5 = 3(2x + 5) + 4x + 10
20 + 10x + 5 = 6x + 15 + 4x + 10 (distribute)
30 + 10x = 10x + 25 (combine like terms)
10x - 10x = 25 - 30 (move terms)
0 = -5
The simplified equation is always false, regardless of the value of x. Therefore, there are no solutions to this equation. In other words, there is no value of x that would make the original equation true.
So the answer is zero solutions.
Answer:
5(4+2x)+5 =3(2x+5)4x+10
20+10x+5=6x+15+4x+10
25+10x=10x+25
10x-10x=25-25
0=0
This equation has zero solution.

The graph is Jumping Jacks Completed, and the line is labeled Number of Jumping Jacks. Which of the following lists the range and IQR for this data? The range is 23, and the IQR is 37. The range is 40, and the IQR is 37. The range is 40, and the IQR is 23. The range is 37, and the IQR is 23.
Answer:
The range is 37, and the IQR is 23.
Step-by-step explanation:
A box plot (also known as a "box and whisker plot"), is a graph displaying the distribution of a set of data based on a five-number summary.
Five-number summaryMinimum value is at the end of the left whisker.Lower quartile (Q₁) is the left side of the box.Median (Q₂) is the vertical line inside the box.Upper quartile (Q₃) is the right side of the boxMaximum value is at the end of the right whisker.From the given information, the five-number summary of the Jumping Jacks box plot is:
Minimum = 15Lower quartile (Q₁) = 26Median (Q₂) = 40Upper quartile (Q₃) = 49Maximum = 52RangeThe range is the difference between the maximum and minimum values. Therefore, the range for the data is:
\(\sf Range = 52 - 15 = \boxed{\sf 37}\)
Interquartile range (IQR)The IQR is the difference between the upper quartile and the lower quartile. Therefore, the IQR for the data is:
\(\sf IQR = Q_3 - Q_1 = 49 - 26 = \boxed{\sf 23}\)
SummaryThe range is 37, and the IQR is 23.
Calvin can’t decide if he should use 6 or 12 as the common denominator for adding . Which should he choose and why.
Answer:
Calvin should choose 12 as a common denominator for adding, because if 6 is the denominator it will be a mixed number or improper fraction.
Answer:
You really would not know. Common denominator is used to add fractions, and without the equation, you would not know whether 6 or 12 would be a better help. The equation determines whether 6 or 12 would be a better choice.

A.) 3
B.) 4
C.) 5
D.) 6
First Person who gets it right and EXPLAINS will get branliest! :-)
5 is the answer.
Review:What is a cuboid?
A cuboid is a rectangle, but in 3D form.
Do we calculate area or volume in a cuboid?
We calculate the volume for 3D shapes. For 2D shapes, area is used.
If/Then:
Now, if the volume of the cuboid is 24 units³ then:
x × x × y
Now, lets fit all our options to see which one is NOT the dimensions.
Option A:
x × x × 3 = 24 units³
x × x = 12 units³ ✔
This is possible.
Option B:
x × x × 4 = 24 units³
=> x × x = 6 units³ ✔
This is possible.
Option C:
x × x × 5 = 24 units³
=> x × x = 24/5 units³ ❌
This is not possible. This will be our answer.
Option D:
x × x × 6 = 24 units³
=> x × x = 4 units³✔
This is possible.
Conclusion:
So after working on our problem, we can conclude that C is our answer. Hoped this helped.
