To measure the height of a tree, feet would be the most suitable unit .
When determining which unit you would need fewer of to measure a tree, it's important to consider units that are an appropriate scale for the object in question. Since a tree is typically more than a few feet tall, but significantly less than a mile tall, we would use feet as the unit of measurement. Using yards would require us to measure in much smaller segments than a whole yard, and using inches would take a long time to measure the full height. Therefore, the most suitable unit to measure the height of a tree would be feet, as this unit provides a balance between precision and efficiency. For fieldwork where estimation of tree density is needed, aspects like basal area might be measured using a factor prism in a defined plot area, such as a 0.04-ha (0.1-acre) plot, to estimate the density of trees in a larger area.
louis and valentina have 60 toys to build louis builds 1/2of the toys while valentina builds 2/5 how many toys are left
Answer:
6
Step-by-step explanation:
1/2 = 0.5
2/5 = 0.4
60 × 0.5 = 30
60 × 0.4 = 24
30 + 24 = 54
60 - 54 = 6
Answer:
6
Step-by-step explanation:
Louis build 1/2 of the toy and the total of the toy is 60
Which means
1/2×60=30
Valentina build 2/5 toy
2/5×60
120/5
24
So to determine the amount left
It will be
Total-(Louis+Valentina)
60-(30+24)
60-(54)
60-54
6
So the amount left is 6
Albert wants to buys some pens. He is comparing 4 different packs of pens. The number of pens in each pack and the cost of the pack is shown in the table below. Which two packs of pens have the same cost per pen?
Answer:
There are 2 red pens in each pack
There are 3 blue pens in each pack
Step-by-step explanation:
we know that
270=2*3^{3} *5
180=2^{2}*3^{2}*5
Find the Greatest Common Factor (GCF)
The GCF is equal to------> 2*3^{2}*5=90
the greatest number of packs she can make is 90
Find the number of red pens in each pack 180/90=2 red pens
Divide the total number of red pens by the total number of packs
Find the number of blue pens in each pack 270/90=3 blue pens
Divide the total number of blue pens by the total number of packs

What is Venn Diagram?Venn diagram is a diagram denoting two or more sets which is drawn using circles inside a rectangle where the part where the two circle meet denotes the intersection of two sets.
Given is a Venn diagram.
The blue portion of the circle is A.
Pink portion is B.
Green portion is C.
x is inside the blue circle.
So x belongs to A. x ∈ A
So the statement 1 is not true.
x is also inside the pink portion.
So, x ∈ B
x is not inside the green portion.
So, x ∉ C
A ∪ B consists of all the elements inside A and all the elements inside B.
So x ∈ A∪B
Since x ∈ A, x will be included in A ∪ C.
So, x ∈ A∪C
A ∩ B consists of elements which are both in A and B.
Since, x ∈ A and x ∈ B, x ∈ A∩B
Hence all the statements other than first are true.

Given:
Right triangle.
Base = 10
Hypotenuse = 26
To find:
The missing side length
Solution:
Let the missing side length be x.
Using Pythagoras theorem:
In right triangle, square of the hypotenuse is equal to the sum of the squares of the other two sides.
[tex]10^2+x^2=26^2[/tex]
[tex]100+x^2=676[/tex]
Subtract 100 from both sides.
[tex]100+x^2-100=676-100[/tex]
[tex]x^2=576[/tex]
Taking square root on both sides.
[tex]x=24[/tex]
The missing side length of the right triangle is 24.

What is 351.68 rounded to the nearest tenth?
Answer:
351.7
Step-by-step explanation:
The first number after the decimal is the tenth. Round up if the second number is 5 or above, round down if the second number is below 5.
Answer:
351.7
Step-by-step explanation:
Look at the tenths space which is one place to the right of the decimal. It is a 6.
Then look at the number behind it: if the number behind is is 4 or less the number in front stays the same, if the number behind it is 5 or more the number in front goes up one more
so there is an 8 behind the 6, so you round the 6 to a 7

The volume of a sphere is 500 3 πcm3. what is the radius? sphere v = 4 3 πr3 1. substitute value into formula: 500 3 π = 4 3 πr3 2. undo multiplication of 4 3 : 125π = πr3 3. undo multiplication of π: 125 = r3 4. undo cube: 3√125 = r the radius of the sphere is 6 ⇒ 5 cm
Answer:
about 4.9 cm
Step-by-step explanation:
The equation for the volume of a sphere is V= [tex]\frac{4}{3}\pi r^3[/tex] . So, to solve this problem we will plug in 500 for V and solve for the radius, [tex]r[/tex].
500= [tex]\frac{4}{3} \pi r^3[/tex] Multiply both sides by 3: [tex]1500=4\pi r^3[/tex] Divide both sides by 4: [tex]375=\pi r^3[/tex] Divide both sides by [tex]\pi[/tex]: [tex]\frac{375}{\pi } =r^3[/tex] Find the cubed root of both sides: [tex]4.9237=r[/tex] The radius is about 4.9 cmEvan's science class planted sunflower seeds as part of a research project. A student was sent out each week to measure the height of a flower of their choice. The data in the scatter plot shows their findings from week 2 to week 12.
Which function, h(w), approximates the height of the sunflowers after w weeks?
A) h(w) = 0.30x - 1.09
B) h(w) = 0.30x + 1.52
C) h(w) = 3.18x + 3.78
D) h(w) = 3.23x - 4.14
Answer:
D
Step-by-step explanation:
If you graph equation D you get the following graph, which is closest to the plots
It's impossible to determine the accurate function h(w) that approximates the height of the sunflowers after w weeks from the question alone. This would typically involve evaluating a scatter plot and applying linear regression to find the best fitting function. The approximating function would be understood as the one that best matches the given options, minimizing the distance between the data points and the line.
Explanation:The function that approximates the height of the sunflowers after w weeks (h(w)) cannot be determined directly from the question as it depends on the data present in the scatter plot that was mentioned. Given a scatter plot, we would aim to find a function that best approximates the trend or pattern seen in the plot.
It's an instance of linear regression, a statistical method used to model the relationship between a dependent variable (in this case, height of the sunflowers) and one or more independent variables (in this case, number of weeks). Assuming a linear relationship between weeks and the height of the sunflowers, we want to fit a linear equation (like the given options) that represents this correlation, minimizing the distance between the data points and the line.

Consider ...

Multiply both sides by -1, and it is true only if you reverse the comparison:

Calculate the Rate of Return on an initial investment of $6,000 valued at $6,500.
Answer:
8.3%
Step-by-step explanation:
The rate of return on initial investment is 8.34%.
What is the percentage?
The percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.
Given that the investment is $6,000 and valued at $6,500. The rate of the return will be calculated as,
Rate of return = ( 6500 - 6000) / 6000
Rate of return = 800 / 6000
Rate of return = 8.34%
Therefore, the rate of return on initial investment is 8.34%.

The time it takes for a canoe to go 3 miles upstream and back 3 miles downstream is 4 hours. The current in the lake is 1 mile per hour. Find the average speed of the canoe.
Final answer:
The average speed of the canoe is 1.5 mph.
Explanation:
To find the average speed of the canoe, we need to calculate the time it takes for the canoe to go both upstream and downstream. Let's start with the time it takes to go upstream:
Distance = 3 miles
Speed of canoe = Speed in still water - Speed of current = 8 mph - 1 mph = 7 mph
Time = Distance / Speed = 3 miles / 7 mph = 0.429 hours
Now, let's calculate the time it takes to go downstream:
Distance = 3 miles
Speed of canoe = Speed in still water + Speed of current = 8 mph + 1 mph = 9 mph
Time = Distance / Speed = 3 miles / 9 mph = 0.333 hours
Finally, we can find the average speed of the canoe by dividing the total distance traveled (6 miles) by the total time taken (4 hours): average speed = total distance / total time = 6 miles / 4 hours = 1.5 mph.

In ΔKLM, the measure of ∠M=90°, LK = 25, KM = 7, and ML = 24. What ratio represents the cosine of ∠L?
Answer:
24/25
Step-by-step explanation:
cosin=cah adjacent over hypotenuse
"The correct ratio representing the cosine of ∠L in ΔKLM is [tex]\(\frac{7}{25}\).[/tex]
In right-angled triangle ΔKLM, where ∠M is 90°, the cosine of ∠L is defined as the ratio of the adjacent side to the hypotenuse.
The adjacent side to ∠L is KM, and the hypotenuse is LK.
Given that LK = 25 and KM = 7, the cosine of ∠L is calculated as follows:
[tex]\[ \cos(\angle L) = \frac{\text{Adjacent side (KM)}}{\text{Hypotenuse (LK)}} = \frac{7}{25} \][/tex]
This ratio [tex]\(\frac{7}{25}\)[/tex] represents the cosine of ∠L in ΔKLM."
