Part A: The sun produces 3.9 ⋅ 1033 ergs of radiant energy per second. How many ergs of radiant energy does the sun produce in 1.55 ⋅ 107 seconds? (5 points)
Part B: Which is the more reasonable measurement of the diameter of a human hair:
1.8 ⋅ 10−2 mm or 1.8 ⋅ 102 mm? Justify your answer. (5 points)
Using the multiplication operation, the Number of ergs produced in [tex]1.55 \times 10^{7} [/tex] is [tex] 6.045 \times 10^{40} \: ergs [/tex]
Eggs produced per second = [tex]3.9 \times 10^{33} [/tex] Number of seconds = [tex]1.55 \times 10^{7} [/tex]Total number of ergs produced can be calculated thus :
Ergs per second × number of seconds[tex]3.9 \times 10^{33} \times 1.55 \times 10^{7} = 6.045 \times 10^{33+7} = 6.045 \times 10^{40} \: ergs [/tex]
Therefore, the Number of ergs produced in [tex]1.55 \times 10^{7} [/tex] is [tex] 6.045 \times 10^{40} \: ergs [/tex]
B.)
Due to the very small measure of the diameter of the human hair, a measure of [tex]1.8 \times 10^{2} mm[/tex] would be too large, Hence, the value [tex]1.8 \times 10^{-2} mm[/tex] would be more appropriate

The ratio of Maggie's age now to her brother Steven's age now is 2:3. In ten years, the ratio of their ages will be 4:5. How old in Maggie now? Do not label years old in your answer.
Answer quick please! <3
Answer:
sorry if this is wrong
Step-by-step explanation:
Maggie = X
Brother = 2X-3 <--- 3 years younger than twice her age.
2x - 3 + x = 24 <--- the sum of their ages is 24
3x - 3 = 24
3x = 27
x = 9
Maggie is 9.
Brother is 2*9 - 3 = 18 - 3 = 15

To measure the distance across a pond, a surveyor locates points A, B, C, D, and E as shown. Find the length of AB to the nearest meter. Explain how you got this answer.
Answer:
formula with a squared term.
It’s not about distance in the sense of walking diagonally across a room. It’s about any distance, like the “distance” between our movie preferences or colors.
If it can be measured, it can be compared with the Pythagorean Theorem. Let’s see why.
Understanding The Theorem
We agree the theorem works. In any right triangle:
pythagorean theorem
If a=3 and b=4, then c=5. Easy, right?
Well, a key observation is that a and b are at right angles (notice the little red box). Movement in one direction has no impact on the other.
It’s a bit like North/South vs. East/West. Moving North does not change your East/West direction, and vice-versa — the directions are independent (the geek term is orthogonal).
The Pythagorean Theorem lets you use find the shortest path distance between orthogonal directions. So it’s not really about right triangles — it’s about comparing “things” moving at right angles.
You: If I walk 3 blocks East and 4 blocks North, how far am I from my starting point?
Me: 5 blocks, as the crow flies. Be sure to bring adequate provisions for your journey.
You: Uh, ok.
So what is “c”?
Well, we could think of c as just a number, but that keeps us in boring triangle-land. I like to think of c as a combination of a and b.
But it’s not a simple combination like addition — after all, c doesn’t equal a + b. It’s more a combination of components — the Pythagorean theorem lets us combine orthogonal components in a manner similar to addition. And there’s the magic.
In our example, C is 5 blocks of “distance”. But it’s more than that: it contains a combination of 3 blocks East and 4 blocks North. Moving along C means you go East and North at the same time. Neat way to think about it, eh?
From the picture attached,
AB and ED are the parallel sides of two triangles ΔCDE and ΔCBA.Measure of sidesDE = 5 m, CD = 5 m, CE = 4 m and CA = 12 m
In ΔCDE and ΔCBA,
Two sides AB and ED are parallel and two lines AC and BC are intersecting these lines,
Therefore, ∠CDE ≅ ∠CBA and ∠CED ≅ ∠CAB [Corresponding angles]
By AA postulate of similarity,
ΔCDE ~ ΔCBA.
By using the property of two similar triangles,
"Corresponding sides of two similar triangles are proportional"
[tex]\frac{CE}{CA}= \frac{DE}{BA}[/tex]
[tex]\frac{4}{12}= \frac{5}{AB}[/tex]
[tex]AB=\frac{5\times 12}{4}[/tex]
[tex]AB=15[/tex] m
Therefore, length of AB will be 15 meters.

Answer:
Yellow = 2/3(Blue)
Step-by-step explanation:
You only really need the first row of the table since it shows the volume of yellow to the volume of blue.
Before we write the equation we have to find the ratio and to do that we divide.
Divide the amount of yellow by the amount of blue:
3.5/ 5.25 = 0.666 = 2/3
now we can write the eqaution:
Yellow = 2/3(Blue)
Erion plans to tile the floor of his kitchen. The kitchen is 11 feet by 15 feet. The tiles he will be using are square, measuring 8 inches on each side, and are sold in boxes that contain enough tile to cover 25 square feet. How many boxes of tiles must he order to complete the job?
Answer:
First, find the area for the kitchen floor: 16.5*15=247.5 squared feet
Then find the area for one tile: 0.5*0.5=0.25 squared feet
Finally, divide the mayor area between the minor: 247.5/0.25= 990 tiles.
Also you can do it in this another way:
First, divide length of the kitchen floor between the length of one tile: 16.5/0.5=33
Then, do the same for the height: 15/0.5=30
Finally multyply both results: 33*30= 990 tiles.
Step-by-step explanation:
or just 990

What is linear expression?
A linear expression is an algebraic statement where each term is either a constant or variable raised to the power one.
We have to given some steps of equation.
Now, The complete steps to solve the equation are;
1/5t + 2 - ____ = 17 - _____
Subtract 2 from both sides;
⇒ 1/5t + 2 - 2 = 17 - 2
