the length of the shadow is 30m

hypotenuse = 50m

height of tree = 40 m

To solve the question, we will use an illustration:

To get the length of the shadow, we will apply pythagoras' theorem:

Hypotenuse² = opposite² + adjacent²

hypotenuse = 50m, opposite = 40m

50² = 40² + shadow²

2500 = 1600 + shadow²

2500 - 1600 = shadow²

900 = shadow²

square root both sides:

Hence, the length of the shadow is 30m

The adjacent side of the central angle is the x-coordinate and the opposite side of the central angle is the y-coordinate

A pair of numbers that use the horizontal and vertical separations from the two reference axes to define a point's location on a coordinate plane. typically expressed by the x-value and y-value pair (x,y).

The hypotenuse is the radius of a unit circle whose origin serves as its center. Allow being the central angle.

x = Adjacent Side of the central angle

y = Opposite Side of the Central angle

The x-coordinate is the central angle's adjacent side, while the y-coordinate is its opposite side.

Mathematics is a branch of science that deals with numbers, quantities and shapes. It includes arithmetic, geometric, algebra, calculus and many more. It also refers to the study of relationship between numbers or items.

One example is counting numbers which we are using almost everyday in our life.

1, 2, 3, 4 and so on.

we have that

The temperature T in degrees Celsius (°C) is equal to the temperature T in Kelvin (K) minus 273.15

so

°C=K-273.15

For T=55°C

substitute

55=k-273.15

solve for k

k=55+273.15

The number of boxes he needs to place = 279÷ 24 = 11.625 ≈ 12.

Multiplication is the opposite of division. If 3 groups of 4 add up to 12, then 12 divided into 3 groups of equal size results in 4 in each group.

Creating equal groups or determining how many people are in each group after a fair distribution is the basic objective of division.

In the aforementioned scenario, you would need to place four donuts in each group in order to divide 12 donuts into three similar groups. Thus, 12 divided by 3 will result in the number 4.

Dividend: Divisor x Quotient + Remainder

Given : Number of diners = 279

And the number of boxes = 24

Thus to find out the number of boxes he needs to place = 279÷ 24 = 11.625 ≈ 12.

Solution:

In geometry, a line segment is a part of a line that is bounded by two distinct endpoints and contains every point on the line that is between its endpoints. The angle of rotational symmetry or angle of rotation is the smallest angle for which the figure can be rotated to coincide with itself.

A rotation is a transformation in a plane that turns every point of a figure through a specified angle and direction about a fixed point. The fixed point is called the center of rotation

Rotation of a line does not change the length of the line segments

Reflection does not preserve orientation.

Dilation (scaling), rotation, and translation (shift) do preserve it.

The coordinates of endpoint J which has the midpoint M(–17, 16.5) and endpoint K(–12, 4) is (-22,29)

Mid point:

Midpoint means the point that is in the middle of the line joining two points.

Given two points A (x)1, (y)1 and B (x)2, (y)2, the midpoint between A and B is given by,

M(x)3, (y)3 = [(x)1 + (x)2]/2, [(y)1 + (y)2]/2

where, M is the midpoint between A and B, and (x)3, (y)3 are its coordinates.

Given,

JK has midpoint M(–17, 16.5) and endpoint K(–12, 4).

Here we need to find the coordinates of endpoint J.

We know that formula of mid point through the given definition,

So let us consider

(x1, y1) = (a, b)

(x2, y2) = (-12,4)

Now we have to apply the values on the formula in order to solve it,

Therefore,

(-17, 16.5) = (a + (-12))/2 , (b + 4)/2

Compare the values individually, then we get,

-17 = (a - 12) / 2

-17 x 2 = a - 12

- 34 = a - 12

a = -34 + 12

a = -22

Similarly, when we take the second part,

16.5 = (b+4)/2

16.5 x 2 = b + 4

33 = b+ 4

b = 33 - 4

b = 29

Therefore, the coordinate end points of J is (-22, 29).

The investment will be worth $7,401.22 after 10 years

Here, we want to calculate the amount the investment will be worth after 10 years

Mathematically, to get this, we will use the compound interest formula;

where A is the amount after 10 years

P is the amount invested which is $5,000

r is the interest rate which is 4%, same as 4/100 = 0.04

n is the number of terms yearly the investment will be compounded. Since the interest rate is annual, then the number of times it will be compounded yearly is 1

t is the number of years which is 10 in this case

Substituting these values, we have;

The distance between the points is 6.7 units

The distance between two points is the number of points between them

The points are given as

(0, 5) and (3, -1)

The distance formula is given as

d = √(x2 - x1)^2 + (y2 - y1)^2

Substitute the given points in the above distance formula

So, we have

d = √(0 - 3)^2 + (5 + 1)^2

Evaluate the difference and the sum

d = √(-3)^2 + 6^2

Evaluate the exponents

d = √9 + 36

Evaluate the sum

d = √45

This gives

d = 6.7

Hence, the distance is 6.7 units

It is closer to [tex]1[/tex] than [tex]0[/tex], so the statement is True.

Step-by-step explanation:

Step 1: Finding the decimal form of [tex]\frac{8}{11}[/tex]

Upon simplification on a calculator, we can see that the exact value of [tex]\frac{8}{11}[/tex] is:

[tex]0.7272727273[/tex]

Let's round this to [tex]0.73[/tex] for an easier time.

Step 2: Identifying the value's difference from 1 and 0

We have found the value of the fraction to be [tex]0.73[/tex].

If we subtract the value from [tex]1[/tex], we get:

[tex]1-0.73\\=0.27[/tex]

If we find the difference between it and [tex]0[/tex], we get:

[tex]0.73-0\\=0.73[/tex]

As we can see, the value is [tex]0.27[/tex] units away from [tex]1[/tex], but is [tex]0.73[/tex] units away from [tex]0[/tex].

We can clearly see that it is closer to [tex]1[/tex], so the statement is True.
