Photons of red light have a wavelength of approximately $7\times 10^{-7}$ meters. The energy of a photon is inversely proportional to its wavelength. A photon with 2000 times the energy as a photon of red light will have a wavelength that can be written as $a\cdot 10^b$ meters, where $1\le a < 10$. (In other words, in scientific notation.) What is $a+b$ written as a decimal?

The folding chair has different settings that change the angles formed by its parts. Suppose m∠2 is 31 and m∠3 is 65. Find m∠1. The diagram is not to scale.
Answer:
m∠2=31
m∠3=65
m∠1=?
Notice that measure of angle 2,3 and the angle that's next to angle 1 will form a triangle. Let's name the angle next to 1 to be x.
31+65+x = 180
96+x = 180
x = 180-96
x = 84
Now, you can easily find the m∠1.
84+m∠1 = 180 (REASON: Linear pair)
m∠1 = 180-84
m∠1 = 96
What are rational numbers
Answer:
In mathematics, a rational number is a number that can be expressed as the quotient or fraction p/q of two integers, a numerator p and a non-zero denominator q. Since q may be equal to 1, every integer is a rational number.
Any number that can be written as a fraction with integers is called a rational number . For example, 17 and −34 are rational numbers

Insect is crawling in a straight line at a speed of 12cm/s how far will the insect travel in 35 seconds
Answer:
420cm
Step-by-step explanation:
speedxtime=distance
12x35=420
Answer:
Distance = 420cm/s
Step-by-step explanation:
We have been given that Insect is crawling in a straight line at a speed of 12cm/s.
We have the following outcomes from the question.
Speed of insect = 12cm/sSo, We need to find the distance which can be reached out by insect in next 35 Seconds.
We are familiar with distance formula which is given by , Distance = Speed × Time
Distance = Speed × Time
Or, Distance = 12cm/s × 35
Or, Distance = 420 cm/s
Therefore, Insect is crawling in a straight line at a speed of 12cm/s, 420cm/s will the insect travel in 35 seconds.

Jane and Jillian are hiking around a hill and one complete circle is 8 miles long. They start together but hike in opposite directions. Both start to hike at 8:00 AM. Jane's hiking speed is 3 mph and Jillian's hiking speed is 5 mph. How long will it take before they meet? At what time will they meet? In how many hours? What time will they meet at?
Answer:
It will tale 1 hour before they meet and they will meet agin at 9 :00 AM.
Step-by-step explanation:
Speed of Jane, [tex]v_1=3[/tex] mph
and the speed of Jillian, [tex]v_2= 5[/tex] mph.
Length of one complete circle = 8 miles.
Both are moving in the opposite direction, let the starting point is at O, and met at the point P after time, t, as shown in the figure.
Let the length covered by Jane via path OAP= x miles.
[tex]\Rightarrow x= 3t[/tex] [as distance= speed x time]
[tex]\Rightarrow t=x/3 \cdots(i)[/tex]
The length covered by Jillian via path OBP [tex]= 8-x[/tex] miles
[tex]\Rightarrow 8-x= 5t[/tex] [as distance = speed x time]
[tex]\Rightarrow t=(8-x)/5 \cdots(i)[/tex]
Now from equation (i) and (ii),
[tex]\frac{x}{3} = \frac{8-x}{3}[/tex]
[tex]\Rightarrow 5x=3(8-x)[/tex]
[tex]\Rightarrow 5x+3x=24[/tex]
[tex]\Rightarrow x=3[/tex]
So, the distanc covered by Jane = 3 miles and
the distanc covered by Jillian = 8-3=5 miles
From equation (i), time taken, t = 3/3= 1 hour.
So, it will tale 1 hour before they meet.
As the startion time was 8:00 AM, so the will agin meet at 9 :00 AM.

The triangles shown below must be congruent.
Answer:
The question asks if they must be congruent, so the answer is false
Step-by-step explanation:
All the angles are equal
47 = 47
62=62
71=71
The side between the 62 and 71 equals 7 on the left, we are not given the side between the 62 and the 71 on the right so we do not know if the triangles are congruent. We need to have one of the sides be equal for the triangles to be congruent.
The question asks if they must be congruent, so the answer is false
Answer:
FALSE

When you flip a biased coin the probability of getting a tail is 0.46.
Find the probability of getting a head.
Answer:
54%
Step-by-step explanation:
Getting a head or a tail are two mutually exclusive events. Thus, given that probability of getting a tail is 0.46, the probability of getting a head is 0.54.
What are mutually exclusive events?Two events are mutually exclusive or disjoint if they cannot both occur at the same time.
P(getting a head) + P(getting a tail) = 1
(Getting a head and getting a tail are mutually exclusive events. This implies that when we toss a coin, we either get a head or a tail.)
P(getting a head) + 0.46 = 1
P(getting a head) = 1 - 0.46 = 0.54

Answer:
Step-by-step explanation:
Ist method - Area of the triangle + Area of the trapezium
Area of triangle = 1/2 × b × h
here, b = 8 cm but h is not given
so we will find h by pythagoras theorem
AC^2 = AB^2 + BC^2
10^2 = 8^2 + BC^2
100 = 64 + BC^2
BC^2 = 36
BC = √36
BC = 6
∴ h = 6cm
area of triangle = 1/2 × b × h
= 1/2 × 8 × 6
= 24 cm^2
Area of trapezium = 1/2 ( a + b ) h
Here a = 13cm
b = 25 - 8 = 17 cm
h = 6 cm
So area = 1/2 ( a + b ) h
= 1/2 ( 13 + 17 ) 6
= 90 cm^2
So total area = Area of the triangle + Area of the trapezium
= 24 cm^2 + 90 cm^2 = 114 cm^2
2nd method - Area of the entire figure
Since the figure is a trapezium,
Area of trapezium = 1/2 ( a + b ) h
here, a = 13cm
b = 25 cm
h = 6 cm
Area of trapezium = 1/2 ( a + b ) h
= 1/2 ( 13 + 25 ) 6
= 114 cm^2

step-by-step explanation:
A poll conducted the day before the student- body presidential election at a midwestern university showed that 53.9 percent favored Mario, the rest favoring Yin Ling. The margin of error was 4.2 percentage points. Should Yin Ling have conceded the election?
Answer:
No
Step-by-step explanation:
The confidence interval of the percentage of people that favored Mario = number of votes favoring Mario ± Margin of error
The confidence interval = 53.9% ± 4.2% = (49.7%, 58.1%)
This means that between 49.7% to 58.1% of the people would have voted for Mario.
Hence Yin Ling would not have won the election, since there is a probability that 50% would have voted for Mario

the circle shows the radius of 12mm what is the circumference
Answer:
24π or about 75.4 mm
Step-by-step explanation:
The circumference of a circle is denoted by C = 2πr, where r is the radius.
Here, we see that r = 12, so plugging this in:
C = 2πr
C = 2π * 12 = 24π ≈ 75.4 mm
The answer is thus 24π or about 75.4 mm.

Answer:
