Find (8.4×108) ÷ (1.2×103). Express your answer in scientific notation.
Answer: 7.33980582 x 10^0
Step-by-step explanation:
Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10. The sign of the exponent will depend on the direction you are moving the decimal.
The expression in scientific notation is 7 ×10^5
What is the basic arithmetic operations?The four basic mathematical operations are Addition, subtraction, multiplication, and division.
Given that the terms are;
(8.4×10^8) ÷ (1.2×10^3)
Step 1: Divide the numerical parts:
8.4 ÷ 1.2 = 7
Step 2: Subtract the exponents:
10^8 /10^3 = 10^5
Now Putting the numerical part and the exponent together, we get:
7 ×10^5
Hence, the result of the expression in scientific notation is; 7 ×10^5

Ahmad run 5 kilometres. If he completed 15% of the race. How many kilometres is the race?
Answer:
x = 33.33 kilometers
Step-by-step explanation:
you could make use of the percent, base, and rate formula here. we know that 15% is the rate, 5 kilometers is the percent, therefore what we are looking for is our base.
[tex]\frac{percent}{base} =\frac{rate}{100}[/tex]
[tex]\frac{5}{x}=\frac{15}{100}[/tex] ; cross multiply.
15x = 500
x = 33.33 kilometers
therefore, the race is 33.33 kilometers.
Answer:
33.33
Step-by-step explanation:
15%/100 and 15%=5KM 5=15% so make it 1% 5÷15=0.3333..... = 1% therefore time it to 100×0.3333 (1%) = 33.33KM is the total race KM

y = 2x + 2Step-by-step explanation:
Find the y-intercept first, then, from that point, go tide over run to find your slope. This line has a positive slope, so count up two and over one (2/1). After that, input what data you've collected into your equation (y = mx + b) and you'll have your answer.

On what intervals are the function's values positive?
10.
What are the zeros of the function?
Answer:
See step by step
Step-by-step explanation:
To find if a function intervals are possible, make sure the points are above the x axis.
The graph is getting positve around x=-3 but it isn't positive yet.
The graph is positve until x=-1
The graph becomes positive again again at x=2 and is positive infinitely forever.
So let set up our interval
We are going to start at -3 since that where it start getting positive, we then going to use the greater than sign since it get positve as we go to the right as of right now. We use the greater than becuase we are not going to include -3 as our solutions.
We then use a less than sign since the answer must be less than -1 becuase around-1 it start getting negative.
It becomes positive again at x=2 so since we going to left to right use the greater than sign becuase we are not including 2.
It infinitely becomes positive so our interval is x must be cause greater than w becuase it can be any interval greater than two.
[tex] - 4 > x < - 1[/tex]
and
[tex] 2 < x[/tex]
The roots or zeroes are the x intercept of the graph,(when y=0, what is the x value.)
The x intercepts are -3 and 2.

The semi-circle has a diameter of 8. What is the perimeter of the semi-circle?
Answer:
roughly 12.56 units
Step-by-step explanation:
Since the perimeter of a circle is 2*pi*r, we can divide it by two or multiply by half in order to find the perimeter of a semicircle
half of the diameter is the radius, so 8/2 =4, r=4
Plug in what we know...
C=2*pi*4
Solve
2*3.14*4
25.12
divide by 2
25.12/2=12.56
12.56 units is the perimeter
Answer:
Approx. 20.566 units
Step-by-step explanation:
Find the circumference of the whole circle first by doing:
C = 2πr
r = 4 (8 divided by 2)
C ≈ 25.133
Then divide that by two because a semi-circle is half a circle:
12.566
Then add 8 (diameter) to that number for the open side.

Answer:
y = - x - 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + b ( m is the slope and b the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 2, 1) and (x₂, y₂ ) = (0, - 1) ← 2 points on the line
m = [tex]\frac{-1-1}{0+2}[/tex] = [tex]\frac{-2}{2}[/tex] = - 1
The line crosses the y- axis at (0, - 1 ) ⇒ b = - 1
y = - x - 1 ← equation of line
Answer:
y= - x -1
Step-by-step explanation:
ran it through Desmos
I can't find a way to expllain
it if i would put y= - 1 (becaues remember -1 is where the lines intersected with the y axis)
all there would be was a straight

Points A, B, C, and D are vertices of a square. Point E is inside the square. Explain how to tell whether point E is closer to A, B, C, or D.
Answer:
To determine if a point E inside a square is closer to any of the vertices of the square we have to determine the length of the diagonals between the point E and the vertices of the square i.e. AE, BE, CE, DE
The diagonal can be determined by applying Pythagorean's theorem

Ryan has a toy car collection consisting of 160 toy cars he keeps on the wall and 340 he keeps in a display case. What percentage of Ryan's toy car collection does he keep on his wall?
Answer:
32%
Step-by-step explanation:
First find the whole, the total number of toy cars:
160 on the wall} + 340 \text{ in display case} = }{500} total toy cars}
160 on the wall+340 in display case=500 total toy cars
Method 1: Set up a proportion
Set up an equation of the form:
whole
part
= }{100}
100
percent
Assign the variable xx to the unknown value:x}=
x=
percent
The question asks what }percent of all the toy cars is 160
Substitute the known values with the numbers given in the problem, and the unknown value with xx:
\frac{\color{red}{160}}{\color{orange}{500}}=
500
160
={100}
100
x
Solve for xx:
100}{160}=
100⋅160=
{500}
500⋅x
Cross multiply
16000}{500}=
500
16000
=
{500x}{500}
500
500x
Divide both sides by 25
{32\%}=
32%={x}
x
Simplify
Method 2: Find percent directly
Find \(160\) out of \(500\) as a decimal:}
Find 160 out of 500 as a decimal:
{160} {500}}=
500
160
=
\,\,0.32
0.32
\text{Convert decimal to percent:}
Convert decimal to percent:
0.32\times100=
0.32×100=

32%
Move decimal 2 places to the right
number

160
32%

100%
The percentage of Ryan's toy car collection does he keep on his wall should be considered as the 32%.
Calculation of the percentage:Since Ryan has a toy car collection consisting of 160 toy cars he keeps on the wall and 340 he keeps in a display case.
So here the percentage be like
[tex]= 160 / (160 + 340)[/tex]
= 32%
Hence, The percentage of Ryan's toy car collection does he keep on his wall should be considered as the 32%.

What is Probability?Probability is a branch of mathematics which deals with the occurrence of a random event.
Drawing a certain card from a deck probability depends on whether or not another card has been drawn previously, as it changes the number of cards remaining in the deck and the likelihood of drawing a certain card.
Drawing a pair of cards from a deck is the pair of events which are dependent on one another.
Hence, putting on a pair of pants and a shirt without looking at them are pair of events which are dependent on one another
