Write 0.00005974 in scientific notation.
Answer:
Step-by-step explanation:
For correct scientific notation, we need to have 1 number to the left of the decimal, and everything else to the right. Since our number is already less than 1, the exponent representing the number of places we move the decimal will be negative. We have to move the decimal 5 places to the right to get the 5 to the left of the decimal and everything else to the right, making this:

The yearbook has 12 pages for ads. Each page measures 6 in. By 12 in. Each ad measures 6 in. By 3 in. If all the ad space sells at $10 per ad, how much money will this raise for the yearbook?
Answer:
$480
Step-by-step explanation:
Each page measures 6 in. By 12 in. Each ad measures 6 in. By 3 in
based on the dimensions, there would be 4 ads per page
total ads in 12 pages = 4 x 12 = 48
total cost of ads = 48 x 10 = 480

( x^6 -2x^5 –x^3 — 7) – (3x^6 - 3x^5 -2x^ 2 – 5)
Answer: -2x^6+x^5-x^3-2+2x^2 Hope that helps!
Step-by-step explanation:
1. Remove Parentheses x^6-2x^5-x^3-7-3x^6+3x^5+2x^2+5
2. Collect like terms (x^6-3x^6)+(-2x^5+3x^5)-x^3+(-7+5)+2x^2
3. Simplify and your answer would be -2x^6+x^5-x^3-2+2x^2

2x + 3y = 12
15x -3y = 39
Answer:
x=3 y=2
Step-by-step explanation:
Step one:
Add both equation
2x+3y=12
+ 15x-3y=39
___________
17x=51
x=3
Step 2: After finding the answer for x, plug it into the first equation to find the value of y
2(3)+3y=12

Answer:
118°
Step-by-step explanation:
Don't think the answer is 62° this time both 118° and angle x are congruent.
What do I mean by that? Both angles measure the exact same thing.
The only difference is their line length (n) and (m).

WILL AWARD BRAINLIEST
Answer:
a₂₇ = -81
Step-by-step explanation:
Given that,
The first term of an AP is, a₁ = 49
8th term of the AP, a₈ = 14
nth term of an AP is given by :
[tex]a_n=a_1+(n-1)d\\\\a_8=49+7d\\\\14=49+7d\\\\7d=-35\\\\d=-5[/tex]
27th term of the AP is given by :
[tex]a_{27}=a_1+26d\\\\=49+26(-5)\\\\=-81[/tex]
So, 27th term of the AP is -81.

Solve the following equation for x: 3x - 8 = 25
Answer:
x = 11
Step-by-step explanation:
First you isolate the 3x to one side by adding 8 to both sides, this then gives us the equation 3x = 33, then you divide 33/3 which equals 11
Find the slope-intercept equation of the line that passes through (2,-5) and has a slope of 1/3
Answer:
y = 1/3x - 17/3
Step-by-step explanation:
Given:
Passes through (2, -5)
m = 1/3
Slope-intercept:
y - y1 = m(x - x1)
y - (-5) = 1/3(x - 2)
y + 5 = 1/3x - 2/3
y = 1/3x - 17/3
