Answer: 3.90125×10⁻³
Step-by-step explanation:
The scientific notation consists of two parts
the number based: a, where 0<a<10the exponent based: 10ˣ, which is determined by how we change the number based "a"So the final version should be: a×10ˣ
-------------------------------------------------------------------
STEP ONE. Number based
We are given 3,901.25
In order to make it within the range of a, we should move the decimal to the left three places, or divide the number by 10³, which is times 10⁻³
We get 3.90125
STEP TWO: Exponent based
Since we changed the number by 10⁻³, this will be our exponent-based.
Therefore, it is 3.90125×10⁻³
Hope this helps!! :)
Please let me know if you have any questions
Me and my friends have been arguing over this for a long time since we can't do math-
What's the answer to 10-10x100-23? I got -1013, and the one is screaming that it's wrong.
Answer:
ur right
it's -1013
bc you need to do multiplication first so the equation turns out to be
10 - 1000 - 23
so then that turns to -1013 if you calculate left to right

hi can someone help me with this?
Answer:
h = 4.5 units
Step-by-step explanation:
The area (A) of a triangle is calculated as
A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the height )
Here A = 6.75 and b = 3 , then
[tex]\frac{1}{2}[/tex] × 3h = 6.75
1.5h = 6.75 ( divide both sides by 1.5 )
h = 4.5
we have
base [b]=3 units
height [h]=x units
area of triangle =6.75 square units
we have
area of triangle =1/2 b×h
6.75 square units =1/2×3×x
x=6.75×2/3=4.5units
so height is 4.5 units.
please help !!!!!!!!!
Answer:
The angle between the ramp and the horizontal is 11.54 degrees
Step-by-step explanation:
Here, we want to get the angle between the ramp and the horizontal
What we have to do here is to bring the measure of 2 m near to the edge leftwards, so we can have a right triangle
Now, the angle we want to calculate is the angle that faces the measure 2 m
The given measure of 10 m will represent the hypotenuse of the right triangle
The trigonometric ratio that links the hypotenuse and the opposite is the sine
The sine is the ratio of the opposite to the hypotenuse
Thus, we have it that;
sin theta = opp/hyp
sin theta = 2/10
sin theta = 0.2
theta = sin^-1 0.2
theta = 11.54

Answer:32
Step-by-step explanation: The volume of A is 32:)
HELP IM DOIN A MATH TEST AND IM STUCK!!!!! Tim knows the volume In bass area of a wooden chest that is in the shape of a rectangular prism. If the volume is 5/24 Of a cubic unit and the base area is 1/5 of a square unit, What is the height of the chest?
Answer:
Height is 1 1/24 unit.
Step-by-step explanation:
Given:
volume = 5/24 unit³
base area = 1/5 unit²
Rectangular prism:
volume = length * width * height
base area = length * width
Volume = base area * height
height = volume / base area
h = 5/24 ÷ 1/5
h = 5/24 * 5/1 = 5*5 /24*1 = 25/24 = 1 1/24 unit

After 20,% discount a mobile set is bought at rupees 13920 find the marked price of the mobile set. Maths question
Step-by-step explanation:
First of all, let us lay down the clues;
●There is a 20% discount on the mobile set.
●The price after the discount is Rs 13 920
●We need to find the original price.ie.(100% stands for original price)
Now let's start;As there is a 20% Discount on the m.Set, we need to find the exact percentage decrease.
So,
100%-20%= 80%
Now let's do Direct Proportion,
80%= Rs 13 920
1%= 13 920/80
100%= 13 920/80*100=Rs 17 400

Use substitution to solve the
following system of equations.
9x + 5y = 32 AND y = -3x + 4
Answer:
x = -2
y = 10
Step-by-step explanation:
Since they already gave y as -3x +4, you will then have to substitute that amount into the formula
9x + 5y = 32
By doing that you get
9x +5(-3x+4) = 32
9x -15x +20 = 32
Then, you ill take 20 to the other side to subtract 32, which will get you
-6x = 12
Then, you will get x = -2
Then substitute that for the equation
y = -3x + 4
You will get
y = -3(-2) + 4,
You will get y as 10
SO then your final answer is x = -2, y = 10

Leah is mixing peanut butter candy (p) that sells for $3.60 per pound with chocolate candy (c) that sells for $2.00 per pound. She needs 50 pounds of the mixture to sell in her store for $2.16 per pound. Which system of linear equations can Leah use to determine the number of pounds of each candy to use?
Answer:
45 pounds of the chocolate candy and 5 pounds of the peanut butter candy.
Step-by-step explanation:
let's define the variables:
p = pounds of peanut butter candy she uses
c = pounds of chocolate candy she uses.
We know that she wants to have a total of 50 pounds of the mixture, then we will have that:
p + c = 50
We also want that these 50 pounds sell for $2.16 per pound.
Then we must have that the price for the candies in the mixture must be equal to the desired price, we can write this as:
p*$3.60 + c*$2.00 = (50 )*($2.16 )
Then we have the system of equations:
p + c = 50
p*$3.60 + c*$2.00 = (50)*($2.16) = $108
To solve this, we first need to isolate one of the variables in one of the equations. I will isolate p in the first equation to get:
p = 50 - c
Now we can replace this in the other equation to get:
(50 - c)*$3.60 + c*$2.00 = $108
Now we can solve this for c.
$180 - c*$3.60 + c*$2.00 = $108
$180 - c*$1.60 = $108
$180 - $108 = c*$1.60
$72 = c*$1.60
$72/$1.60 = c = 45
This means that she should use 45 lb of the chocolate candy, and using the equation:
p + c = 50
p + 45 = 50
p = 50 - 45 = 5
p = 5
She should use 5 lb of the peanut butter candy.

Answer:
4. 12c(3a^5b - 1)
Step-by-step explanation:
Greatest common factor of 36 and 12: 12
There are variables a^5b on left term but not on right term, so there is no common factor of a or b.
Greatest common factor of c and c: c
Common factor: 12c
36a^5bc / 12c = 3a^5b
-12c / 12c = -1
Answer: 36a^5bc - 12c = 12c(3a^5b - 1)
Awad claims that when m is a negative integer and n is a positive integer, n - m is always negative. Is Awad’s claim true or false? Explain your reasoning. If it is true, give an example to support his claim. If it is false, give a counterexample. Explain your reasoning..
Answer:
False
Step-by-step explanation:
False, because whenever you subtract a negative number, you always end up adding because two negatives make a positive. Lets say n is 4 and m is -3, 4-(-3) is going to turn into 4+3=7.
The Awad'claims that "when m is a negative integer and n is a positive integer, n - m is always negative". which is false.
What is the number system?A number system is defined as a way to represent numbers on the number line using a set of symbols and approaches. These symbols, which are known as digits, are numbered 0 through 9. Based on the basic value of its digits, different types of number systems exist.
Awad claims that when m is a negative integer and n is a positive integer, n - m is always negative.
The above claim is false because subtracting a negative integer always results in an addition because two negatives equal a positive.
For example, n is 6 and m is -2; 6 -(-2) will equal 6 + 2 = 8.
Hence, the Awad'claims that "when m is a negative integer and n is a positive integer, n - m is always negative". which is false.

A 25-foot ladder is leaned against a wall. If the base of the ladder is 7 feet from the wall, how high up the wall will the ladder reach?
Answer:
24ft
Step-by-step explanation:
Pythagorean Theorem!!
[tex]a^2 + b^2 = c^2[/tex]
------------------------
In this case, the ladder is c, and the base is b.
------------------------
Plug the numbers in the formula.
[tex]a^2 + 7^2 = 25^2[/tex]
------------------------
Solve.
[tex]a^2 + 49 = 625[/tex]
[tex]a^2 -49 = 625 - 49[/tex]
[tex]a^2 = 576[/tex]
[tex]\sqrt{a^2} = \sqrt{576}[/tex]
[tex]a = 24[/tex]
Find the volume of a cone with a height of 6cm and a base radius of 4cm. Use the value 3.14 for π, and do not do any rounding.
Answer:
100.48 cm³
Step-by-step explanation:
Volume of a cone, V = 1/3 * pi * r² * h
Radius, r = 4 cm ; h = 6cm
V = 1/3 * 3.14 * 4² * 6
V = 1/3 * 3.14 * 16 * 6
V = 3.14 * 16 * 2
V = 3.14 * 32
V = 100.48 cm³
Hence, the volume of the cone is 100.48 cm³
