Answer:
2.537 x 10¹⁵ miles
Step-by-step explanation:
We are given the following:
1 light year = 5.9 x 10¹² miles
Distance of the star = 4.3 x 10² light years
To get this we just convert the distance of the star in light years into miles.
We cancel out the light years and then we are left with:
In dealing with scientific notation, when we multiply them we can treat the coefficients and exponents of 10 separately.
Coefficients:
4.3 x 5.9 = 25.37
Exponents of 10:
10² x 10¹² = 10⁽²⁺¹²⁾=10¹⁴
Then we combine them again to form a scientific notation:
25.37 x 10¹⁴
But since the standard in writing a scientific notation, the coefficient needs to be a number from 1-9, we need to move the decimal. When we move the decimal to the right or left, we change the exponent of the power of 10. Since we will move it once to the left, we add 1.
The answer will then be:
2.537 x 10¹⁵ miles

A vitamin C tablet contains 140 of a gram of vitamin C. You take 112 tablets every day. In simplest form, how many grams of vitamin C do you take every day?
17808 grams of vitamin c taken everyday
dann that's a lot of vitamin c
Answer:
3/80 of vitamin C everyday
Step-by-step explanation:
Given :A vitamin c tablet contains 1/40 of a gram of vitamin c
To Find : how many many grams of vitamin c do you take everyday
Solution :
A vitamin c tablet contains a gram of vitamin c = 1/40
You take 1 1/2 = 3/2 tablets everyday
1 tablet contain vitamin C = 1/40
contain vitamin C = 1/40 x 3/2
that means you take 3/80 grams a day

Write the following expression in simplest form.
(3 + 16.4a) − (9 + 5.7a)
22.1a + (−12)
1.07a + (−12)
22.1a + (−6)
10.7a + (−6)
Answer:
10.7a + (−6)
Step-by-step explanation:
Let's simplify step-by-step.
3+16.4a−(9+5.7a)
Distribute the Negative Sign:
=3+16.4a+−1(9+5.7a)
=3+16.4a+(−1)(9)+−1(5.7a)
=3+16.4a+−9+−5.7a
Combine Like Terms:
=3+16.4a+−9+−5.7a
=(16.4a+−5.7a)+(3+−9)
=10.7a+−6
Option D is correct. The expression in its simplest form is: 10.7a - 6.
Let's simplify the given expression:
(3 + 16.4a) − (9 + 5.7a)
Distribute the negative sign to the terms inside the second parentheses:
(3 + 16.4a) − 9 − 5.7a
Combine like terms:
(16.4a - 5.7a) + (3 - 9)
Perform the subtraction and subtraction of coefficients:
(16.4a - 5.7a) + (-6)
Simplify the expression:
(10.7a) - 6
So, the expression in its simplest form is: 10.7a - 6. Option D is correct.

Which expression is equivalent to 4(2.61y − 3.08)?
A - 10.44y + 3.08
B - 10.44y − 3.08
C - 10.44y + 12.32
D - 10.44y − 12.32
Answer: B
I am like 99% sure this is correct if not let me know
The equivalent expression is indeed 10.44y - 12.32 (option d).
let's break down the process of distributing the 4 to both terms inside the parentheses step by step:
Given expression: 4(2.61y - 3.08)
Distribute the 4 to both terms inside the parentheses:
4 * 2.61y - 4 * 3.08
Multiply 4 by 2.61y:
10.44y
Multiply 4 by 3.08:
-12.32
Now, putting it all together, the distributed expression becomes:
10.44y - 12.32
Therefore, after distributing the 4 to both terms inside the parentheses, the equivalent expression is indeed 10.44y - 12.32. This matches option D - "10.44y - 12.32".

This is a scale drawing of a deck. The actual deck has a perimeter of 120 ft. Draw another scale drawing of the deck using the scale 15 ft to 1 unit from the deck to the drawing. Explain your reasoning.
The scale 15 ft to 1 unit from the deck to the drawing will give a perimeter of 8 units.
How to calculate the scale?From the information, the actual deck has a perimeter of 120 ft.
Therefore, another scale drawing of the deck using the scale 15 ft to 1 unit from the deck to the drawing will be:
= Normal perimeter / Scale used
= 120 / 15
= 8
Therefore, the scale 15 ft to 1 unit from the deck to the drawing will give a perimeter of 8 units.

Step-by-step explanation:
The average number of viewers over the two weeks is 3.85 x 10 ^4
The given parameters are:
Week 1 = 3.6 x 10 ^4 viewers
Week 2 = 4.1 x 10 ^4 viewers
The average is calculated as:
Average = (Week 1 + Week 2)/2
This gives-
Average = (3.6 x 10 ^4 + 4.1 x 10 ^4)/2
Evaluate the sum:
Average = (7.7 x 10 ^4)/2

You have been hired by your neighbor to babysit their children on Friday night. You are paid $8 per hour.
Based on the table, is the pay proportional to the hours worked?
Yes
No
Answer:
Yes
Step-by-step explanation:
For every hour you will be earning $8.
On the table if you divide the dollars by the hour worked you will receive $8.
Therefore it must be correct
Answer:
Yes
Step-by-step explanation:
Divide the Pay by the Hours Worked to solve how many dollars you are earning per hour.
8/1 = 8 dollar per hour
16/2 = 8 dollars per hour
24/3 = 8 dollars per hour
32/4 = 8 dollars per hour
36/4.5 = 8 dollars per hour
40/5 = 8 dollars per hour
48/6 = 8 dollars per hour
52/6.5 = 8 dollars per hour

Answer: The answer for 4 is 7 and for 6 it's 14 and the slash means to divide
Step-by-step explanation: (14-9)+2 first solve the parentheses then the outside so 14-9 would be 5 and you would 5+2 which then equals 7. then for the second we do the same solve within the parentheses 8+6 equals 14/ 2-1 then we subtract and have 14/1 and anything divided by 1 stays the same which equals 14.
