There are 14 apples in a basket. 8 of these are green. The rest of them are red. (a) what is the ratio of green apples to red apples? (b) what is the ratio of red apples to all apples in the basket?
6:8 - 6 red apples to 8 green apples. 1:1.33 - 1 red apple for every 1.33 green apples. 43% of the apples are red and 57% of the apples are green.
Final answer:
The ratio of green apples to red apples is 4:3, and the ratio of red apples to all apples in the basket is 3:7 after simplification.
Explanation:
To solve the student's question:
First, we find the ratio of green apples to red apples. There are 14 apples in total, 8 of which are green, so 14 - 8 = 6 red apples. The ratio of green to red apples is therefore 8:6, which can be simplified by dividing both sides by 2, resulting in a simplified ratio of 4:3.
Next, we calculate the ratio of red apples to all apples in the basket. Since there are 6 red apples and 14 apples in total, the ratio is 6:14, which simplifies to 3:7 when both sides are divided by 2.
Therefore, the answer for part (a) is a ratio of 4:3, and for part (b) is a ratio of 3:7.

please help me
Answer:
Your answer would be 36
Step-by-step explanation:
You can figure this out by multiplying B by C to get A or
4 x 9 = 36
Then you can check by going
36 ÷ 4 = 9
9 = 9
This is the right answer
Answer:
36
Step-by-step explanation:
You are solving for ?. Let ? become the variable (x).
x ÷ 4 = 9
Note the equal sign, what you do to one side, you do to the other. Isolate the variable, x. To do so, multiply 4 to both sides:
x ÷ 4 (* 4) = 9 (* 4)
x = 9 * 4
x = 36
36 is your answer.

Six students eat 6 apples in 33 seconds. How long will it take nine students to eat 19 apples, if they don't cut apples into parts?
Answer:
99
Step-by-step explanation:
It takes each student 33 seconds to eat an apple. This is done in parallel.
The time it would take if each person ate the exact same amount of apples is 69.6 repeating (calculated by (19 * 33) / 9). However, the apples cannot be cut into parts, so we need to round up to the next multiple of 33. Therefore 99 is the answer.

A student has a container with a volume of 2.5 liters. She estimates the volume to be 2.8 liters. By
what percent is the student's estimate off?
Answer:
12 percent
Step-by-step explanation:
2.5 ÷ 100 = 0.025
2.8 - 2.5 = 0.3
0.3 ÷ 0.025 = 12
The percent change is 12%.
What is Percent Change?When you want to analyse how a value has evolved over time, percentage increase is helpful. Although percentage increase and absolute increase are fairly comparable, the former is more helpful when contrasting different data sets.
Given:
A student has a container with a volume of 2.5 liters.
She estimates the volume to be 2.8 liters.
Change in Amount
= 2.8-2.5
= 0.3
So, percent increase
= 0.3 / 2.5 x 100
= 0.12 x 100
= 12%
Hence, the percent change is 12%.

A region with a 15-mile diameter has a population density of about 5000 people
per square mile. Find the number of people who live in the region.
Answer:
Approximately 883,572 people
Step-by-step explanation:
I'm assuming the region is a circle.
The formula for finding the area of a circle is A=πr².
Since we know that the diameter of the region is 15 miles, and a diameter is 2 times the radius, the radius must be 7.5 miles. We also know that π is equal to 3.14159265359.
A=πr²
A= 3.14159265359×7.5²
A= 3.14159265359×56.25
A= 176.714586764
The region has an area of 176.714586764 square miles.
176.714586764×5000=883572.933822
We can round this number to the nearest whole, but since we cannot have part of a person, the answer is approximately 883,572 people.
Final answer:
To find the number of people who live in a region with a 15-mile diameter and a population density of 5000 people per square mile, we can calculate the area of the region and then multiply it by the population density.
Explanation:
To find the number of people who live in the region, we need to calculate the area of the region and then multiply it by the population density. The region has a 15-mile diameter, so the radius is half of that, which is 7.5 miles. The formula for the area of a circle is A = πr^2, where π is approximately 3.14. Plugging in the values, the area of the region is A = 3.14 × (7.5)^2 = 176.625 square miles.
Next, we multiply the area by the population density of 5000 people per square mile: 176.625 × 5000 = 883,125 people.
Therefore, there are approximately 883,125 people who live in the region.

What is the center of the circle given by the
equation (x + 17)2 + (y − 4)2 = 23?
A. (−4, 17)
B. (−17, 4)
C. (17, −4)
D. (4, −17)
Answer:
B. (−17, 4)
Step-by-step explanation:
We can write the equation of a circle in the form
(x-h)^2 + (y-k)^2 = r^2 where (h,k) is the center and r is the radius
(x + 17)^2 + (y − 4)^2 = 23
(x - -17)^2 + (y − 4)^2 = ( sqrt (23))^2
The center is (-17,4) and the radius is (sqrt(23)

Which graph represents the function f (x) = StartFraction 2 x Over x squared minus 1 EndFraction?
Answer:
Step-by-step explanation:
f(x) = 2 / (x^2 - 1) is better written as
2
f(x) = ------------------
(x - 1)(x + 1)
This is undefined at x = -1 and x = 1; there are vertical asymptotes at x = -1 and x = 1.
The y-intercept is found by letting x = 0; we get
2
f(x) = ------------------ = -2 => (0, -2)
(0 - 1)(0 + 1)
Please, next time, share the answer choices. Thank you.
By analyzing the asymptotes we can find the graph of the rational function. Also a graph is provided below.
Which graph represents the function?We have the rational function:
f(x) = (2x)/(x^2 - 1).
First, you can see that we have two zeros on the denominator. One happens when x = 1 and the other when x = -1.
This means that the graph of this function will have two vertical asymptotes at these values. (four actually as we have one going to each end in each point).
With that description we can find the graph of the function, I will also post it so you can recognize it.

If the interest rates are the same on a CD, which compounding pays more interest?
annually
semi-annually
monthly
quarterly
The CD that compounds more frequently will pay more interest; thus, monthly compounding yields more interest than quarterly, which in turn is more than semi-annually, with annual compounding paying the least.
Explanation:When comparing the different compounding frequencies for a Certificate of Deposit (CD) with the same annual interest rate, the compounding option that pays more interest is the one that compounds more frequently. Compounding can occur on an annual, semi-annual, quarterly, or monthly basis. The more frequently the interest is compounded, the greater the amount of interest will be earned because each compounding period, the interest is calculated on the initially invested amount plus the previously earned interest.
For example, if interest is compounded monthly, it will be compounded 12 times a year, and each month's interest will begin to earn interest in subsequent months. Similarly, if interest is compounded quarterly, it will be compounded 4 times a year, and semi-annually compounding will occur twice a year. The least frequent is annually compounding, with only one compound per year.
Therefore, the CD that compounds monthly will pay the most interest, followed by the one that compounds quarterly, then semi-annually, and the least will be the CD that compounds annually, assuming the nominal interest rate is the same for all.
Clarence made a scale drawing of a classroom. The scale in the drawing is 2 inches represents
9 feet. The actual length of the classroom is 36 feet. What is the length of the classroom on the
scale drawing?
A4 inches
B 8 inches
OC 27 inches
OD 162 inches
Answer:
The answer is B
Step-by-step explanation: The reason for this is you know that 2 in = 9ft so you multiply 9 to get 36/ the height of the classroom. The times you multiply is by equal to it by you multiply by 2 because 2= 9ft not 1=9ft so you take 4 and multiply by 2 and you get 8.
Answer:
B) 8 inches
Step-by-step explanation:
Since the scale of the drawing is 2:9, we will then make this into two fractions that equal each other to make this easier. To do this we will make the ratio 2:9 into a fraction being 2/9. Then we will make the missing value which is the length of the calssroom on the scale drawing over the actual length of the classroom which is 36. We will then make the fractions equal each other. 2/9 = x/36. We can either cross multiply ( 2 x 36 and 9 * x) or we can make the denominators the same. I am going to make the denominators the same. The equation will then look like this: 8/36=x/36. Now we know the value of x is 8. This makes the answer B) 8 inches.

Parallelogram:A simple (non-self-intersecting) quadrilateral with two sets of parallel sides is known as a parallelogram in Euclidean geometry. A parallelogram's facing or opposing sides are of equal length, and its opposing angles are of similar size. The Euclidean parallel postulate or one of its equivalent formulations must be used in order to demonstrate the congruence of opposed sides and opposite angles because both conditions are a direct result of this postulate.In contrast, a quadrilateral with only one set of parallel sides is referred to as a trapezoid or trapezium in British or American English.The parallelepiped is a parallelogram's three-dimensional equivalent.
Therefore, the correct answer to the question is 7 XS.

Suppose y varies inversely with x. Write an equation if y=7 when x=-4
Answer:
y = -28 ÷ x
Step-by-step explanation:
The standard format of a inversely proportional equation goes by the format of y = k ÷ x. The question asks us to write an equation if y = 7 when x = -4 and y varies inversely with x.
So we substitute the values y = 7 and x = -4 in the equation y = k ÷ x
K = constant, we have to work this out
7 = k ÷ -4
7 × - 4 = k
k = - 4 × 7
k = -28
k = -28 So then we put this back into the original y = k ÷ x to find our final equation which is y = -28 ÷ x
