Answer 1

Answer:

1)13/3 2)-1/2 3)5/6

Step-by-step explanation:

1) Determine the sign(since there is 2 negatives it turns positive)

Then you simplify the complex fraction to 4/3+3

Then you calculate

2) Determine the signs you get to -6+4/-1+5

calculate -2/4

then solve

3) multiply everything to get 8-(5+(-12))/16+2

Then you calculate 8-(5-12)/18

Calculate again8-(-7)/18

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)

Answers

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

Relate a vertical line test to understanding functions.
a.
Each horizontal line drawn through the graph will intersect a function in only one location
c.
Each vertical line drawn through the graph will intersect a relation in only one location
b.
Each vertical line drawn through the graph will intersect a function in many locations
d.
Each vertical line drawn through the graph will intersect a function in only one location


Please select the best answer from the choices provided

A
B
C
D

Answers

Answer: Choice D

Each vertical line drawn through the graph will intersect a function in only one location.

This is another way of saying that for any input x, there is exactly one output y. If you had a vertical line cross through a curve at multiple points, then this would mean that x input produces multiple y outputs, and we won't have a function. A function must produce one output whatever the input is (assuming the input is in the domain of course).

I think it’s D hope it helps! 1

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?

Answers

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:

There are 213 calories in three ounces of a certain ice cream. How many calories are there in one pound?
1 pound = 16 ounces
Before you try that problem, answer the question below.
How many ounces will you need to find the number of calories for? ( don;t forget Convert the given number of pounds to ounces)

Answers

Answer:

1. considering that there are 16 ounces in one pound, and the question is asking for one pound, I would think that there would only need to be 16 ounces observed.

2. Through calculations of the given number of oz, there are 71 calories per oz. By multiplying that by 16 (the number of oz in a lb) there are a total of 1,136 calories in a lb.

I believe the answer is 1,163 calories, I could be totally wrong..

1/a^2+a+1 put in fraction form

Answer:

1/36

Step-by-step explanation:

notice the first equation is the second equation squared.

For instance, look at the numerator: a squared is a^2

Look at the denominator: a^2 squared is a^4 and so on.

So if the second equation is 1/6, then you need to square it to have it equal the second equation: (1/6)^2 = 1/36

Answers

Answer: n=−36

Step-by-step explanation: When a fraction equals zero ...

Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.

Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.

Here's how:

 n+36

 ———— • 3 = 0 • 3

  3  

Now, on the left hand side, the  3  cancels out the denominator, while, on the right hand side, zero times anything is still zero.

The equation now takes the shape :

  n+36  = 0

 Solve  :    n+36 = 0  

Subtract  36  from both sides of the equation :  

                     n = -36

1. Distribute to clear out parentheses
2. Subtract 2 from both sides
3. Multiply by 3 on both sides

Answer:

Step-by-step explanation:

Working days : 5

Working hours : 3.5 + 4 = 7.5 Hours

Earning in a day = 7.5 * 18.75 = 140.625

Earning in the week (working days only): 140.625 * 5 = 703.125

In the last week Mrs. Rodriguez earned $703.125

How to know how much money did she make for the entire week's work ?

According to the problem,

Mrs. Rodriguez worked 5 days last week. She worked 3.5 hours before and 4 hours after lunch. Mrs. Rodriguez earned $18.75 per hour.

Total hours of work = (3.5 + 4) hours = 7.5 hours in one day

In 5 days she worked (7.5 x 5) hours = 37.5 hours

In the last week Mrs. Rodriguez worked 37.5 hours.

∴ Amount of money she earned =  $ (37.5 x 18.75) = $703.125
