Answer:
8.9 × 10^{4}
Step-by-step explanation:
Calculating scientific notation for a positive integer is simple, as it always follows this notation: a x 10b.
Follow the steps below to see how 89,000 is written in scientific notation.
Step 1
To find a, take the number and move a decimal place to the right one position.
Original Number: 89,000
New Number: 8.9000
Step 2
Now, to find b, count how many places to the right of the decimal.
New Number: 8 . 9 0 0 0
Decimal Count: 1 2 3 4
There are 4 places to the right of the decimal place.
Step 3
Building upon what we know above, we can now reconstruct the number into scientific notation.
Remember, the notation is: a x 10b
a = 8.9 (Please notice any zeroes on the end have been removed)
b = 4
Now the whole thing:
8.9 x 10^{4}
Step 4
Check your work:
10^{4} = 10,000 x 8.9 = 89,000

Step-by-step explanation:
a pile of sand has a weight of 90 kg the sand is put into a small bag a medium bag and a large bag in the ratio 2:3:7
work out the wight of sand in each bag
Answer:
15 kg, 22.5 kg, 52.5 kg
Step-by-step explanation:
Let the common multiplier of the given ratios be x. Therefore, weights of each bag would be 2x, 3x and 7x
According to the given information:
[tex]2x + 3x + 7x = 90 \\ 12x = 90 \\ x = \frac{90}{12} \\ x = 7.5 \: \\ \implies \\ 2x = 2 \times 7.5 = 15 \: kg \\ 3x = 3 \times 7.5 = 22.5 \: kg \\ 7x = 7 \times 7.5 = 52.5 \: kg[/tex]
Hence the weight of sand in bag would be 15 kg, 22.5 kg and 52.5 kg
Draw Conclusions Suppose that A and C are real numbers and A is not 0. What are the x- and y-intercepts of the equation Ay = C? Explain.
Answer:
Horizontal line which goes through the y -axis at the coordinate ( 0, C/A ).
Step-by-step explanation:
Since A is not 0 then C can not be 0 This is a logical deduction from the given formula Ay = C
The equation of any line is y = ax + b, where a is the incline and b is the intercept between the line and the y- axis.
Ay = C
Divide left and right of the = sign by A and you get:
y = C/A
This is the formula for a horizontal line which goes through the y -axis at the coordinate ( 0, C/A ).
Because it is a horizontal line it has an incline of 0.
So a = 0
y = ax + b
a = 0 and b = C/A
y = 0*x + C/A
y = 0 + C/A
y = C/A
What do you know about Scientific Notation
Answer:
Scientific notation is a way of expressing, and handling, a mathematical expression used to represent a decimal number between 1 and 10 (multiplied by ten), so large numbers can be made with using less digits. An example would be writing 4 x 10³ for 4,000.

Step-by-step explanation:
On an actual basketball court, the bench area is 9 meters long. How long should the bench be on the scale drawing?
Step-by-step explanation:
Note: It is not given that, 1 cm represents 2m
The bench area on an actual basketball court is 9 meters long.
We need to find how long should the bench be on the scale drawing. Since 1 cm represents 2m. It means 1 m represents 0.5 cm
9 meters will represent,
[tex]\dfrac{9}{0.5}\ cm\\\\=18\ cm[/tex]
Hence, the bench is 18 cm long.
is 0.65 repeating greater than or less than 13/20?
Answer:
its equal
Step-by-step explanation:
Answer:
Since 13/20 is exactly 0.65, then 0.6565656565......(repeating) is greater than 13/20.

X - 6 - 8 = -19 + x
Answer: infinite solutions, one solution, zero, no solution
Answer:
No solution.
Step-by-step explanation:
[tex]x-6-8=-19+x[/tex]
Subtract x from both sides:
[tex]x-6-8-x=-19+x-x[/tex]
[tex]-6-8=-19[/tex]
[tex]-14=-19[/tex]
Since both sides are not equal, there is no solution.
