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
Answers
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.

Answers
The answer is a and b.
Here's the way to check:
Since all the numbers follow a constant sequence, it is possible to use division. Minus the first term, then divide it by the pattern of the sequence.
For a, 512 - 8 = 504
The pattern from a is each number is increased by 7. So,
504 ÷ 7 = 72
The number itself you count is not important. The point is that the number could be divided fully without remainder. This means 512 will appear in the sequence.
Repeat the above steps for b and c:
512 - 23 = 489
489 ÷ 3 = 163
It can be divided without remainder, 512 appears in this sequence.
512 - 12 = 500
500 ÷ 12 = 41.66666
Since C is a decimal ( there is remainder ), the number 512 does NOT appear in the sequence.
However, if you want to know the logic of WHY this works, I won't be able to give you a satisfying answer. Hope this helps you.

How to define a linear function?The slope-intercept representation of a linear function is given by the equation presented as follows:
y = mx + b
The coefficients of the function and their meaning are described as follows:
m is the slope of the function, representing the change in the output variable y when the input variable x is increased by one.b is the y-intercept of the function, which is the initial value of the function, i.e., the numeric value of the function when the input variable x assumes a value of 0. On a graph, it is the value of y when the graph of the function crosses the y-axis.The slope and the intercept for the function in this problem are given as follows:
Slope of -1.22, meaning that for an increase of one degree Fahrenheit, the predicted decrease in the cost is of $1.22.Intercept of 96.2, meaning that the predicted heating cost for a month with temperature of 0 ºF is of $96.20.Hence, the predicted cost for a month with temperature of 25ºF is given as follows:
y = -1.22(25) + 96.20 = $65.70.

pls help me
Answers
Answer:
D is the right choice and no you cannot fit the pizza inside the box.
Step-by-step explanation:
D is the answer because to turn 2/3 into a decimal you would divide 2 by 3 and the answer you would get would be 0.66666666666...You would then add 12 to the answer and get 12.6666... Once you get this answer you would round it to the hundredths to get 12.67 but since that is not an option you could use D, 12.66 inches.

I believe the answer is D.

Mean = 16
Step-by-step explanation:
MEAN can be find bg the sum of all score divided by the amount of the score.
Mean = total amount / number of amount
Total amount = 2 + 3 + 5 + 9 + 17+ 22 + 31 + 39
= 128
number of amount = 2, 3, 5, 9, 17, 22, 31, 39
= 8
Then we can calculate mean as
Mean = 128/8
Mean = 16
2+3+5+9+17+22+31+39=128
128/8=16

(5/2)² < 12.06 but
If y is supposed to be a factor, like multiply by 2, then
(5/2)²y > 12.06
Step-by-step explanation: substitute 2 for y
20y - 5² = 2
20(2) - 25 =
40 - 25 = 15
__________
(5/2)² = 5²/2²
25/4 = 6.25 . So that is less than 12.06
But if y is supposed to be a factor, like multiply by 2, then
(5/2)²y > 12.06
