Answer:
Two things we need to remember:
Speed of light = c = 299,792,458 m / s
This means that the light in one second covers a distance of 299,792,458 m
And for a circle of radius R, the is:
C = 2*pi*R
where:
pi = 3.14
Then if the radius of the earth is 6,378.1 km, then the of the earth is:
C = 2*(3.14)*6,378.1 km = 40,054.468 km
And we know that 1 km = 1000m
Then the circumference of the earth is:
C = (40,054.468*1000) m = 40,054,468 m
Now we need to see how many times the light can encircle the earth per second. (we assume that the light can move in a circular path, this is not really accurate to the reality)
We know that in one second the light can cover a distance of: 299,792,458 m
And the circumference of the earth is: 40,054,468 m
The quotient between these two distances is the number of times that the light can encircle the earth:
N = (299,792,458 m)/(40,054,468 m) = 7.5
So light could encircle the earth 7.5 times per second.

In parallelogram HJKL if m<KLH=170 find m<LHJ
Answer:
bro what is even happening here
so confused but okay
Answer:
∠ LHJ = 10°
Step-by-step explanation:
Consecutive angles in a parallelogram sum to 180°
Then
∠ KLH + ∠ LHJ = 180°
170° + ∠ LHJ = 180° ( subtract 170° from both sides )
∠ LHJ = 10°

Which equation would demonstrate the identity property? A. (3 • 4) + (3 • 5) = 3(4 + 5) B. 3 • 5 = 5 • 3 C. 3 • 4 • 5 = (3• 4) • 5 D. 4 • 1 = 4
Answer:
D. 4 • 1 = 4
Step-by-step explanation:
In Mathematics, we have two kinds of Identity property
a) Identity property of Addition
This means that when you add a number to zero, it gives you that same number
Example: 6 + 0 = 6
b) Identity property of Multiplication,
This means that, when a number is multiplied by 1, it gives that same number.
Example: 8 × 1 = 8
Therefore, from the above question, the equation that demonstrates identity property is 4 • 1 = 4

A licorice rope is 7 inches long. If four 5th graders share the licorice equally amongst themselves, what length of licorice will each student get?
Answer:
1.4 Inches Each
Step-by-step explanation:
This problem is fairly simple. Just divide 7 by 5 and put the correct units(inches) with the answer.
length of licorice each student will get is 1.875 inches.
What is simplification?A mathematical expression gets simpler when it is transformed into an equivalent, frequently shorter statement. One strategy for promoting uniformity in job effort, cost, and time is procedure simplification. It lessens diversity and variation that is harmful, unwanted, or unneeded.
Given, A licorice rope is 7 inches long. If four 5th graders share the licorice equally amongst themselves.
Since every 5th grader is sharing the rope equally.
Thus everyone will get = 7/4
Every 5th grader will get = 1.875 inches
Therefore, every 5th grader will get 1.875 inches length of licorice.

3x+2x -4--6
5x-10
The expressions that are equivalent to 3x - 4 + 2x - 6 are:
5x - 2 - 6
5x - 16
To determine which expressions are equivalent to 3x - 4 + 2x - 6, we can simplify the given expression:
3x - 4 + 2x - 6
Combining like terms, we have:
(3x + 2x) + (-4 - 6)
Simplifying further:
5x - 10
Now, we can compare this simplified expression to the provided options:
a) 3x + 2x - 10
b) 5x - 2 - 6
c) 5x - 16
d) 6x - 10
By comparing the simplified expression 5x - 10 to the options, we find that options b) (5x - 2 - 6) and c) (5x - 16) are equivalent expressions.

Answer:
Length of smaller side = 15 inches
Length of bigger side = 36 inches
Length of hypotenuse = 39 inches
Step-by-step explanation:
Given:
Length of smaller side = a
Length of bigger side = (a + 21) inches
Length of hypotenuse = (a + 24) inches
Find:
Length of all side
Computation:
Using Pythagorean theorem
Hypotenuse² = Base² + Perpendicular²
(a+24)² = a² + (a+21)²
a² + 576 + 48a = a² + a² + 441 + 42a
a² - 6a - 135 = 0
(a-15)(a+7)
So
a = 15 inches a = -7 inches
So,
Length of smaller side = a = 15 inches
Length of bigger side = (a + 21) inches = 15 + 21 = 36 inches
Length of hypotenuse = (a + 24) inches = 15 + 24 = 39 inches

Answer:
hello the table related to this question is missing attached below is the missing table
answer : An exponential function is much better fit because there is no fixed rate in the table
Step-by-step explanation:
An exponential function is much better fit because there is no fixed rate in the table attached but the values in the table keeps increasing exponentially, hence an Exponential function will be a better fit, But a linear function would be preferred only if there is a fixed rate

Answer:
Step-by-step explanation:

The side BC and AC and the angle B is 108 m,180 m and 59°.
What is the triangle?A triangle is a polygon that has three sides and three angles. The sum of the angle of the triangle is 180 degrees.
[tex]\rm sin \theta = \frac{P}{H} \\\\ \rm sin 31^0= \frac{a}{210} \\\\ a=108 \ m[/tex]
[tex]\rm cos \theta = \frac{B}{H} \\\\ \rm cos 31^0 = \frac{b}{210} \\\\ b=180 \ m[/tex]
The measure of the angle of triangle is 180°
∠A+∠B+∠C=180°
31°+∠B+90°=180°
∠B=59°
Hence, the side BC and AC and the angle B is 108 m,180 m and 59°.

What are the trigonometric ratios?Trigonometric ratios for a right-angled triangle are from the perspective of a particular non-right angle.
In a right-angled triangle, two such angles are there which are not right angled(not of 90 degrees).
The slanted side is called the hypotenuse.
From the considered angle, the side opposite to it is called perpendicular, and the remaining side will be called the base.
It is given that
JLK = 72°
JM = 14

In the given diagram, the value of x is 15
Pythagorean theoremThe Pythagorean theorem states that, in a right triangle, the square of the longest side (hypotenuse) equals sum of squares of the other two sides
From the question, we are to determine the value of x.
x is the radius of the circle
Recall: Radius is any line that runs from the center to any part of the circumference
Consider the right triangle formed, x is the hypotenuse
By the Pythagorean theorem,
x² = 9² + 12²
x² = 81 + 144
x² = 225
x = √225
x = 15
Hence, the value of x is 15.

The number of bacterial cells, B, in a container after t hours is given by B=25x2t After how many hours will there be 400 bacterial cells in the container?
Answer:
8 hours
Step-by-step explanation:
We have that;
B = number of bacterial cells, B, in a container after t hours
t = time taken in hours
The function is;
B=25x2t
Where B = 400 bacterial cells
400 = 25x2t
t = 400/25x2
t = 8 hours
The fountain is made up of two semicircles and one quarter circle. Find the perimeter and area of the fountain.
Answer:
628ft²
Step-by-step explanation:
From the diagram, we are given the following
diameter of the semicircles
2semi circles = 1 circle
Area of 2semicircles = πd²/4
Area of 2semicircles = 3.14(20)²/4
Area of 2semicircles = 3.14*400/4
Area of 2semicircles = 3.14*100
Area of 2semicircles = 314ft²
Area of the quarter circle = πd²/4 * 1/4
Area of the quarter circle = πd²/16
d = 2r
d = 2*20
d = 40ft
Area of the quarter circle = 3.14(40)²/16
Area of the quarter circle = 3.14*1600/16
Area of the quarter circle = 3.14*100
Area of the quarter circle = 314ft²
Area of the fountain = 314ft²+314ft²
Area of the fountain = 628ft²
