Pecan trees yield 45 pounds per acre and hazelnut trees yield 25 pounds per acre. Suppose Jenna's farm has p acres of pecan trees, h acres of hazelnut trees, and yields 900 pounds of nuts. What is the equation that represents this scenario? 70n = 900 25p + 45h = 900 a + m = 900 45p + 25h = 900
Let P = Pecan trees and H = Hazelnut trees.
Multiply the number of acres of each by the number of pounds of each acre:
45 pounds per acre of Pecan trees would be 45p
25 pounds per acre of hazelnut trees would be 25h
You would then add those together to get the total pounds of nuts:
45p + 25h = 900
The answer would be D, 45p + 25h = 900
What is the value of f? 6f − 12 = −4f + 6

C. 1 4/5
D. 9
The answer is D! Aight hope it helped
The value of f in the equation 6f − 12 = −4f + 6 is 1 4/5.
Explanation:To answer the student's question, we need to solve the algebraic equation 6f − 12 = −4f + 6 for the unknown variable f. First, we want to get all terms with f on one side of the equation, and all constant terms on the other side. Thus, we'll add 4f to each side of the equation to eliminate -4f from the right side of the equation and get 6f + 4f = 6 + 12. This simplifies to 10f = 18, then we divide each side by 10, and we get f = 18/10 which reduces to f = 1 4/5 (Option C).

the low temperature yesterday was -5 degrees F. the temperature rose as many degreese above zero as the low temperature was below zero to reach the high temperature. wich expression could be used to find the number of degrees between the low and high temperatures? A. 0-5
B. -5+5
C. 5+5
D. -5+0
it is b i know it -5-5=0
Final answer:
The correct expression to find the temperature difference between the low and high temperatures when the temperature rose as much above zero as it was below zero is 5 + 5 degrees, which equals 10 degrees in total.
Explanation:
The question involves finding the difference in temperature from a low of -5 degrees Fahrenheit to a high that is as many degrees above zero as the low was below zero. To calculate the difference, we consider the increase in temperature from the low to 0 degrees, which is 5 degrees, and then the additional increase to the high temperature, which is also 5 degrees above zero. Therefore, the total change in temperature is 5 degrees (to get to zero) plus another 5 degrees (to reach the high), totaling 10 degrees.
The correct expression to find the number of degrees between the low and high temperatures would be C. 5 + 5, representing the increase from -5 degrees to 0, and from 0 to +5 degrees, respectively.

A ladybug's length is 2cm. Measure it in meters. And Explain your thinking.
1m = 100cm.
so since the ladybug is 2cm.
you divide 2 by 100, which you will get 0.02m (divide by 100 means moving the dot two times to the left. thats why it leaves you 0.02m)
0.02 meters would be the length of the lady bug because 1 cm is equal to 0.01 meters
Shane and Karen want to measure the length of a soccer field. Should they use centimeters or meters to measure it. Explain
Hello!
They should most definitely use meters. Meters are much bigger than centimeters as centimeters are 1/100th of a meter. Meaning, it will take 100 centimeters to get 1 meter. A soccer field is a large surface, and to get a simpler number, you should use meters.

You have a normal distribution of hours per week that music students practice. The mean of the values is 8 and the standard deviation of the values is 4. According to the normal distribution model that corresponds to this population, what percentage of the students practice between 6 to 10 hours per week? Use the graph of the standard normal distribution given below to find the percentage. 19% 30% 34% 38%
Answer:
38%
Step-by-step explanation:
Given that X,the hours per week the music student practice follow a normal distribution.
X:N(8,4)
We have to find the percentage of students who practice between 6 and 10 hours.
6<x<10 implies converting to z
We know z = (x-mean)/sigma = (x-8)/4
Hence 6<x<10 is equivalent to (6-8/4)<Z<(10-8/4)
= |z|<0.5
From std normal table we find this area equals = 0.1915+0.1915
=0.3830 = 0.38 (rounded off)
Hence required percentage = 0.38x100 = 38%
Final answer:
To determine the percentage of music students practicing between 6 to 10 hours, we convert these hours to z-scores and use the standard normal distribution table, which reveals that approximately 38.2% of students practice within this range.
Explanation:
To find the percentage of music students who practice between 6 to 10 hours per week, we can use the properties of the normal distribution. We first need to convert the range values to z-scores using the formula Z = (X - μ) / σ, where X is the value from the data set, μ is the mean, and σ is the standard deviation.
Converting 6 hours to a z-score:
Z = (6 - 8) / 4 = -0.5
Converting 10 hours to a z-score:
Z = (10 - 8) / 4 = 0.5
Now we use the standard normal distribution table to find the probability corresponding to these z-scores. The area under the curve between z-scores -0.5 and 0.5 gives us the desired percentage. Looking up the z-scores in the standard normal distribution table, we find that the area between these scores is approximately 38.2%. Thus, 38% is the closest option provided.

the change will be 1.50 because 7.50 minus 9.00 is 1.50
The percent change between $7.50 and $9.00 is calculated by subtracting the initial value from the final value, dividing that by the initial value, and multiplying by 100%. This results in a percent change of 20%.
Explanation:The percent change between two values is calculated by subtracting the initial value from the final value, dividing the result by the initial value, and then multiplying by 100%. In your case, you want to find the percent change between $7.50 and $9.00.
Start by subtracting the initial value ($7.50) from the final value ($9.00). This gives us $1.50.
Then, divide $1.50 by the initial value ($7.50), giving us 0.2.

Solve for x 5a/x = 5b/ x-1
If you cancel out the denominators by multiplying both sides by the bottom, you can then factor to find X= a / (a-b)
To solve the equation 5a/x = 5b/(x-1) for x, multiply both sides of the equation by x(x-1) to clear the fractions. Simplify and solve for x by isolating it on one side of the equation.
Explanation:To solve the equation 5a/x = 5b/(x-1) for x, we need to clear the fractions by multiplying both sides of the equation by the common denominator, x(x-1). This gives us 5a(x-1) = 5bx. Expanding the equation, we get 5ax - 5a = 5bx. Rearranging the terms, we have 5ax - 5bx = 5a. Factoring out x, we get x(5a-5b) = 5a. Finally, dividing both sides by (5a-5b), we can solve for x as x = 5a/(5a-5b).

The scale on the map is 1 cm to 10 km. The distance from Clevend to Cincinnati is 40cm. The scale on the second map is 1 cm to 50 km. What is the distance from Clevend to Cincinnati on the second map? Explain your reasoning
Using the concept of scale, we find that the distance between Cleveland and Cincinnati on the first map (1 cm to 10 km) is 40 cm, equivalent to 400 km in real-world distance. On the second map with a scale of 1 cm to 50 km, the equivalent distance is calculated to be 8 cm.
To calculate the distance between Cleveland and Cincinnati on the second map, we use the concept of scale. On the first map, the scale is 1 cm to 10 km, and the distance is represented as 40 cm. Scaling this to the real-world distance gives us 40 cm × 10 km/cm = 400 km between the two cities.
Now, let's apply the second map's scale of 1 cm to 50 km. To find the corresponding map distance, we set up a proportion: 10 km/cm (first map) / 50 km/cm (second map) = 40 cm (distance on the first map) / X cm (distance on the second map). Simplifying this, we find that X = 40 cm ×(10 km/cm) / (50 km/cm) = 40 cm × 1/5 = 8 cm.
Therefore, the distance between Cleveland and Cincinnati on the second map, which has a scale of 1 cm to 50 km, would be 8 cm.

Hope this helps.
Final answer:
The two numbers that multiply to -120 and add to -2 are 10 and -12. These satisfy the given conditions of multiplication and addition.
Explanation:
To find two numbers that multiply to -120 and add to -2, we can set up a system of equations based on the factors of -120. We know that if two numbers multiply to a negative number, one must be positive and the other negative. So we look for two factors of 120 with a difference of 2, given that one will be negative and the other positive.
Considering the factor pairs of 120: (1, 120), (2, 60), (3, 40), (4, 30), (5, 24), (6, 20), (8, 15), (10, 12), we find that 10 and -12 satisfy both conditions: 10 * -12 = -120 and 10 + (-12) = -2.
