What is the quotient of 4.29 x 10^5 and 9.75 x 10^2 expressed in scientific notation?
The quotient by dividing the given numbers is required.
The quotient is 0.44 x 10³.
DivisionThe given numbers are
4.29 x 10⁵
9.75 x 10²
Let us make the numbers into whole numbers
4.29 x 10² x 10³ = 429 x 10³
9.75 x 10² = 975
So,
(429 x 10³) ÷ 975 = (39 x 11 x 10³) ÷ (39 x 25)
= (11/25) x 10³
= 0.44 x 10³

A pair of perpendicular lines intersect at the point (5,9). Write
the equation of the line that is perpendicular to the line that
also passes through the point (-4,4)
Answer:
The equation of the line that is perpendicular to the line that passes through the point (-4, 2) is y = -9·x/5 + 18
Step-by-step explanation:
The coordinates of the point of intersection of the two lines = (5, 9)
The coordinates of a point on one of the two lines, line 1 = (-4, 4)
The slope of a line perpendicular to another line with slope, m = -1/m
Therefore, we have;
The slope, m₁, of the line 1 with the known point = (9 - 4)/(5 - (-4)) = 5/9
Therefore, the slope, m₂, of the line 2 perpendicular to the line that passes through the point (-4, 4) = -9/5
The equation of the line 2 is given as follows;
y - 9 = -9/5×(x - 5)
y - 9 = -9·x/5 + 9
y = -9·x/5 + 9 + 9
y = -9·x/5 + 18
Therefore, the equation of the line that is perpendicular to the line that passes through the point (-4, 2) is y = -9·x/5 + 18.

What makes -36 in multiplication?
Answer:
Basically the factors of 36 but one number will be negative.
Step-by-step explanation:
negative number x positive number = negative number
-1 x 36 = -36
-2 x 18 = -36
-3 x 12 = -36
-4 x 9 = -36
-6 x 6 = -36
-9 x 4 = -36
-12 x 3 = -36
-18 x 2 = -36
Hope this helps :)
The presence value of a negative sign in the multiplication operation contributes to the final result being -36.
In multiplication, the value -36 can be obtained by multiplying a positive number by a negative number or by multiplying two negative numbers.
For example:
-36 = (-1) × 36
This means that multiplying -1 by 36 gives us -36.
Similarly:
-36 = 6 × (-6)
Here, multiplying 6 by -6 also results in -36.

287 = 78.2 + .5x
208.8 = .5x
x = 417.6
Hope this helps
Answer:
0.5x + 78.2 = 287
0.5x = 287 - 78.2
0.5x = 208.8
0.5x ÷ 0.5 = 208.8 ÷ 0.5

There are 3,785 milliliters in 1 gallon, and there are 4 quarts in 1 gallon. For each question, explain or show reasoning.
1. How many milliliters are in 3 gallons?
2. How many milliliters are in 1 quart?
(Note) Please keep reasonings simple
Answer:
There are 11,355 milliliters in 3 gallons, and 946.25 milliliters in 1 quart.
Step-by-step explanation:
If there are 3,785 milliliters in 1 gallon, multiply each side by 3 because you want the product to equal 3 gallons.3,785 times 3 is equal to 11,355, and 1 times 3 is 3. So, 3 gallons are equal to 11,355 milliliters. If there are 3,785 milliliters in 1 gallon, and there are 4 quarts in 1 gallon, that means that there are 3,785 milliliters in 4 quarts. Now, you want to find the amount of milliliters in 1 quart so you should divide both the 3,785 and the 4 by 4. So, there are 946.25 milliliters in 1 quart.

Answer:
a=3
Step-by-step explanation:
p(x)=x^2-x-6 and f(x)=x^2+3x-18
they have a common factor x=a
so, when they are devided by x-a leave 0 as the remainder ( by remainder theorem)
p(a) =0
f(a)=0
SO, p(a) =f(a)
a^2-a-6=a^2+3a-18
a^2-a^-a-3a= -18+6
-4a= - 12
a=3

A box has four cards numbered 1 to 3 and four Hong will toss a coin wants and record the toss as heads or tails then he will randomly pick a card from the box and record the number chosen give the sample space describing all possible outcomes then give all of the outcomes for the event that the number chosen is three use the format H1 to mean that the coin tosses heads in the number chosen is one if there is more than one element in the set separate them with commas
Answer:
Sample Space = {H1, H2, H3, Hfour, T1, T2, T3, Tfour}
O(Card 3 Chosen) = {H3, T3}
Step-by-step explanation:
A sample space is the set containing all the possible outcomes or results that can occur during an event. In this case the sample space will contain 8 outcomes, and it will be as follows:
Sample Space = {H1, H2, H3, Hfour, T1, T2, T3, Tfour}
Now, it is clear from the sample space that there are total two outcomes in sample space, in which the card numbered 3 is chosen. They are:
O(Card 3 Chosen) = {H3, T3}
where, O represents Outcomes.
The boiling point of water is 212∘F. In degrees Celsius, how much heat do I have to add to boil water that is already 194∘F? Use the formula C = 59(F − 32), where C represents the temperature in degrees Celsius and F represents the temperature in degrees Fahrenheit.
The amount of heat to add to boil the water is 42000J
What is specific heat capacity?The specific heat capacity of a substance is the energy required to raise the temperature of of the substance by 1°C or 1k. It is measured in J/kg/k
The amount of heat to raise temperature is given as
H= mck
where k is the temperature change.
converting 212°f to Celsius
C = 5/9( 212 -32) = 5/9 × 180
= 100°C
converting 194°f to Celsius
C = 5/9( 194 -32)
C = 5/9 × 162
C = 90°C
Therefore;
H = 4200 × 100-90
H = 42000J
Therefore, the amount of heat to boil the water is 42000J.
