The histogram displays the tree growth in one year for a sample of trees measured at Shady Farms.
How many trees measured grew 10 or more inches over the year?
How many trees are represented in the histogram?
Answer:
1.48 2.100
Step-by-step explanation:
To find out how many trees grew 10 or more inches, you should look at the '10 or more inches' section of the histogram and check the frequency, which represents the tree count. To find the total number of trees represented, you should add up the frequencies of all growth rate sections.
Explanation:To determine how many trees measured grew 10 or more inches over the year, you need to look at the histogram for the section that represents 10 or more inches. The y-axis of a histogram indicates frequency, which in this case, means the number of trees. Count the number of instances within the section for 10 or more inches. The total number of trees represented in the histogram can be found by adding the frequency (tree counts) for each section which corresponds to tree growth rates.
For example, if the '10 or more inches' section shows a frequency of 20, it means 20 trees grew 10 or more inches over the year. If the frequencies corresponding to all growth rates total up to 50, it means the histogram represents 50 trees.

Answer:
12y + 11
Step-by-step explanation:
To add them you would add like terms. That means you would add those with y together and those without together.
8y + 4y + 6 + 5 = 12y + 11
If you want to solve for y, subtract 11 from both sides then divide both sides by 12.

Then to find the Volume of the square with the hole in it you would subtract 2,000 and 125 which = 1,875 cm^3
The length of the shortest side of a 30-60-90 triangle is 2 cm. Which of the following is the length of the hypotenuse?
2cm
√3cm
4cm
2 √3cm
Answer:
4 cm
Step-by-step explanation:
The ratios of sides in a 30-60-90 triangle are ...
1 : √3 : 2
The hypotenuse is double the length of the shortest side, so is 4 cm in your triangle.
Final answer:
In a 30-60-90 triangle, if the shortest side is 2 cm, the hypotenuse is twice that length, resulting in a hypotenuse of 4 cm.
Explanation:
The 30-60-90 right triangle has sides in a specific ratio. The lengths of the sides opposite the 30°, 60°, and 90° angles are in the ratio 1:√3:2. If the shortest side is 2 cm, which is opposite the 30° angle, the hypotenuse is twice the length of the shortest side because it is opposite the 90° angle. Therefore, the length of the hypotenuse is 4 cm.

Which of the following is a property of all squares?
A
No sides are parallel.
B
Opposite sides are not congruent.
C
Opposite vertex angles are not congruent.
D
The diagonals bisect each other.
Answer:
D. the diagonals bisect each other
Final answer:
The property of all squares is that their diagonals bisect each other. Other options are incorrect as squares have parallel and congruent sides as well as congruent angles. Therefore, the correct answer is D.
Explanation:
The question asks which of the following is a property of all squares. The correct answer is option D: The diagonals bisect each other. In every square, this property holds true, as squares are a type of rectangle, and in rectangles, the diagonals are congruent and bisect each other. We know that a square has four equal sides and four equal angles, which are right angles.
This implies that not only are the diagonals congruent, but they also divide the square into four congruent right triangles, bisecting one another at their midpoint. Options A, B, and C describe properties that are incorrect for squares, as all sides of a square are parallel and congruent, and all angles are congruent as well.

at2 + vit + hi models the rocket's height as a function of time. The acceleration due to gravity a is 32 ft/s2.
We are to find how long will it take to return to the ground?
Answer:
t = 0.48 sec
Step-by-step explanation:
We are given;
initial velocity; vi = 40 ft/s
hi = 70 ft
acceleration due to gravity; a = 32 ft/s²
Now, we are given that the rocket's height as a function of time is;
h = -12at² + vit + hi
At ground, h = 0
Plugging in the relevant values to obtain ;
0 = -12(32)t² + 40t + 70
-384t² + 40t + 70 = 0
The roots of the equation gives; t = 0.48 sec
Find the length of the missing side
The length of the missing side is
Answer:
52 m
Step-by-step explanation:
a^2 + b^2 = c^2
a^2 + 39^2 = 65^2
a^2 + 1521 = 4225
4225 - 1521 = 2704
Square root of 2704 = 52
Answer:
52m
Step-by-step explanation:
as this is a right angled triangle (has a 90° angle), you can use the Pythagoras theorem to work out the missing side.
Pythagoras theorem:
[tex]a^{2} + b^{2} = c^{2}[/tex]
side A squared (labeled on diagram below)
+ side B squared
= side C squared
for this example though, we don't know the length of side B so we need to swap around the formula.
[tex]c^{2} - a^{2} = b^{2}[/tex]
replace the letters for their numbers,
[tex]65^{2} - 39^{2} = b^{2}[/tex] (calculate)
[tex]65^{2} - 39^{2} = 2704[/tex]
2704 = b² but we want b by itself so we will square root b² (2704)
[tex]\sqrt{2704} = 52[/tex]
∴ side B = 52m (remember we were calculating in meters)
I hope this was helpful :-)

68 is 17% of what number?
Enter
Answer:
400
Step-by-step explanation:
Is means equals and of means multiply
68 = 17% * what number
Change to decimal form
68 = .17 * what number
Divide each side by .17
68/.17 = .17/.17 what number
400 = what number
The number is 400
68 is approximately 17 percent of 400.
To find out what number 68 is 17% of, we can use the following formula:
(17 / 100) x = 68
Let's solve for x:
(17 / 100) x = 68
To isolate x, we can multiply both sides of the equation by (100 / 17):
x = (68 × 100) / 17
x ≈ 400
Therefore, 68 is approximately 17% of 400.
To understand this calculation, think of the percentage as a proportion or ratio. In this case, we are trying to find the ratio of 68 to the unknown number. The result, 0.17, represents how much of the unknown number 68 comprises. By multiplying this ratio by the unknown number, we obtain the value of x, which is approximately 400. Thus, 68 is roughly 17% of 400, indicating that 68 represents 17% of the value 400.

Answer:
x=85
Step-by-step explanation:
The angles are vertical angles, therefore they are congruent. This means we can set them equal to each other.
x+5=90
Solve for x by isolating x. To do this, subtract 5 from both sides
x+5-5=90-5
x=85
So, x=85, and the second choice is correct.
Answer:
It is 85.
Step-by-step explanation:
The angles are vertical from each other so they are equal. 85+5=90.

Point R was rotated about the origin (0,0) by 90° clockwise.
Which figure is the image of R?
The mapping rule for a 90° clockwise rotation is (x, y) → (–y, –x), so R ( 2, -5) becomes (-5, -2).
Answer:Point C is the image of R.
The point C is the image of R.
Here,
Point R was rotated about the origin (0,0) by 90° clockwise.
We have to find the image of R.
What is 90 degree Clockwise rotation?
To rotate the figure 90 degrees clockwise about a point, every point (x,y) will rotate to (y, -x).
Now,
By figure;
Point R is ( 2, -5 )
Now, Point R was rotated about the origin (0,0) by 90° clockwise.
The image of point (x, y) = (y, -x)
Hence, the image of R = (-5, -2 ) = Point C
So, by graph;
Point C is image of Point R.
