Answer:
its 3.45 x 10^5
Step-by-step explanation:
The solution of the given expression will be 3.84 x 10⁻².
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that the expression is 3.99 x 10⁻² - 1.5 x 10⁻³. The expression will be solved as below:-
E = 3.99 x 10⁻² - 1.5 x 10⁻³
E = ( 3.99 x 0.15 ) x 10⁻²
E = 3.85 x 10⁻²
Therefore, the solution of the expression is 10⁻².

What is the slope of a line that is perpendicular to the line 3y - 4x = -8?
♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️
[tex]3y - 4x = - 8[/tex]
Add sides 4x
[tex]3y - 4x + 4x = 4x - 8[/tex]
[tex]3y = 4x - 8[/tex]
Divide sides by 3
[tex] \frac{3}{3} y = \frac{4}{3} x - \frac{8}{3} \\ [/tex]
[tex]y = \frac{4}{3} x - 8 \\ [/tex]
This is the slope-intercept form of the line.
We that the coefficient of the x in slope-intercept form , is the slope of the line.
Thus ;
[tex]slope = \frac{4}{3} \\ [/tex]
_________________________________
Remember from now on ;
Multiply of the slopes of the lines which are perpendicular to each other equal -1 .
Suppose the slope of the line which question asked is m.
So :
[tex] \frac{3}{4} \times m = - 1 \\ [/tex]
Multiply sides by 4
[tex]4 \times \frac{3}{4} \times m = 4 \times ( - 1) \\ [/tex]
[tex]3m = - 4[/tex]
Divide sides by 3
[tex] \frac{3}{3} m = \frac{ - 4}{3} \\ [/tex]
[tex]m = - \frac{4}{3} \\ [/tex]

At a sale, scarves are selling at $50.00 are sold at a loss of 60% of selling
price. What is the loss and the original cost?
Answer?
Answer: $30.00
Step-by-step explanation:
If 100% of 10.00=10.00 / 60% = $6.00
10 x 5 is 50, 6x5 is 30.
So..
60% of $10.00 = $6.00
X5 = $50.00 = $30.00

cy-5=-3d+6y for y. Only on solution
Answer:
This is the answer for your question. I hope it helps you!!!! Pls Mark as the brainliest answer!!!
Step-by-step explanation:
Simplifying
Cy + -5 = -3d + 6y
Reorder the terms:
-5 + yC = -3d + 6y
Solving
-5 + yC = -3d + 6y
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Add '-6y' to each side of the equation.
-5 + -6y + yC = -3d + 6y + -6y
Combine like terms: 6y + -6y = 0
-5 + -6y + yC = -3d + 0
-5 + -6y + yC = -3d
Add '5' to each side of the equation.
-5 + -6y + 5 + yC = 5 + -3d
Reorder the terms:
-5 + 5 + -6y + yC = 5 + -3d
Combine like terms: -5 + 5 = 0
0 + -6y + yC = 5 + -3d
-6y + yC = 5 + -3d
Reorder the terms:
-5 + 3d + -6y + yC = 5 + -3d + -5 + 3d
Reorder the terms:
-5 + 3d + -6y + yC = 5 + -5 + -3d + 3d
Combine like terms: 5 + -5 = 0
-5 + 3d + -6y + yC = 0 + -3d + 3d
-5 + 3d + -6y + yC = -3d + 3d
Combine like terms: -3d + 3d = 0
-5 + 3d + -6y + yC = 0

A ramp that is used to load a truck makes supplementary angles with the ground. The ramp has an incline (<1) of 28. What is the measure of <2?
Answer:
Step-by-step explanation:
two angles are said to be supplementary if their sum is 180 degrees
Hence <1 + <2 = 180
Given
<1 = 28
Required
<2
Substitute into the formula
28+<2 =180
<2 = 180-28
<2= 152
Hence the measure of <2 is 152 degrees

1 9/13 divided by 3/8
|
If you're dividing 9/13 by 3/8, then you have
(9/13) / (3/8) = (9/13) • (8/3) = 72/39 = 24/13
If you're dividing 1 + 9/13 by 3/8, then first write 1 + 9/13 as an improper fraction:
1 + 9/13 = 13/13 + 9/13 = 22/13
Then
(1 + 9/13) / (3/8) = (22/13) / (3/8) = (22/13) • (8/3) = 176/39
choose a linear function for the line representing by the point slope equation y-5=3(x-2)
Answer:
y=3x-1
Step-by-step explanation:
To find the linear function you first need to put the equation into standard slope intercept form which is y=mx+b. m represents the slope and b represents where the line intercepts the y axis.
To figure it out you need to solve for y.
y-5=3(x-2)
Expand 3(x-2) to 3x-6.
y-5=3x-6
Isolate the y by adding 5 to both sides, giving you y=3x-1.
The slope is 3 and the Y intercept is -1.
Mr. Allen has 2 dogs, Spike and Fido. He takes both of them outside at 6:00 a.m. He takes Spike outside every 3 hours. He takes Fido outside every 5 hours. When is the next time Mr. Allen will take both dogs outside at the same time?
Answer:
3 pm
Step-by-step explanation:
Because 3x5 = 15 and 5x3=15 so it would be at 3 pm
Answer:
Step-by-step explanation:
Spike gets taken out every 3 hrs meaning he gets taken out at :
