a x 10b
Follow the steps below to see how 843 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: 843New Number: 8.43Step 2
Now, to find b, count how many places to the right of the decimal.
New Number:8.43Decimal Count:12
There are 2 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 = 8.43
b = 2
Now the whole thing:
8.43 x 102
Step 4
Check your work:
102 = 100 x 8.43 = 843

6≥−6(a+2) solve and find the awnser
Answer:
[tex] - 3 \geqslant a[/tex]
Step-by-step explanation:
[tex]6 \geqslant - 6(a + 2)[/tex]
distribute -6 inside the parentheses
[tex]6 \geqslant - 6a - 12[/tex]
add 12 to both sides
[tex]18 \geqslant - 6a[/tex]
divide by -6 to isolate the variable
[tex] - 3 \geqslant a[/tex]
Answer:
-3<=a
Step-by-step explanation:
1. Get the -6 away, so multiply everything by -6. 6*-6 >= -6*-6(a+2)
2. This becomes -1 <= a+2 Since if you multiply or divide anything by a negative number, you have to reverse the inequality sign.
3. Subtract 2 to get a by itself -1-2 >= a
4. This becomes -3 >= a which is the right answer.
(Just so you know >= and <= means less than or equal to and more than or equal to.)

A book has 240 pages and each day 10 pages are
read. The number of pages left, p, is given as a
function of d, the time in days, where
p = 240 – 10d . Graph the equation, then use its
x-intercept to determine when the book will be
finished?
Answer:
24 days is the answer
Step-by-step explanation:
If the book is 240 pages and each day 10 pages are read you could easily divide 240 by 10 and get 24. However, you need to use the formulas for your answer I suppose. So, to get the x-intercept this is what you do. You have to use the slope-intercept form y = mx+b where m=-10 and b = 240 so you end up with y = -10x+240
So now you solve for x-intercept
0 = -10d+240
subtract 240 from both sides so 0 = -10d + 240
-240 -240
you are left with -240 = -10d. Now simplify and divide each term by -10 -240/-10 = 24 and -10d/-10 = d
you are left with d = 24 or 24 = d
You graph the equation by placing a point at 240 on the y axis and 24 on your X-axis.

-12x+(-4)=56
-2.1x+(-3.9)=10.8
Answer:
X=-5
X=-7
Step-by-step explanation:
-12x+(-4)=56
rewrite the equation to -12x-4=56
add 4 to both sides
-12x=60
Divide by -12 on both sides
x=-5
-2.1x+(-3.9)=10.8
-2.1x-3.9=10.8
-2.1x=14.7
divide by -2.1 on both sides
x=-7
Solve the following literal equation for x.
ax-b/c=d
Answer:
x = (d + b/c)/a
or x = d/a + ba/c
Step-by-step explanation:
1. ax - b/c = d
2. ax = d + b/c
3. x = (d + b/c)/a (can also be written as x = (d + b/c)*1/a)
4. x = d/a + ba/c
Step 1 is given.
In step 2, b/c was added to both sides of the equation. This works because division is ahead of subtraction in the order of operations.
In step 3, both sides were divided by a.
(optional) In step 4, 1/a was multiplied by the values inside the parenthesis as a means to further simplify the equation.

A grocer reports that the store has sold 72 of the 90 boxes of apples delivered this week. What percentage of the delivered apples have been sold?
Answer:
80%
Step-by-step explanation:
Total boxes of apples delivered = 90
Total boxes sold = 72
What percentage of the delivered apples have been sold?
Percentage sold = Total boxes sold / total boxes delivered × 100
= 72 / 90 × 100
= 0.8 × 100
= 80%
The percentage of the delivered apples have been sold is 80%
Percentage unsold = (total boxes delivered - total boxes sold) / total boxes delivered × 100
= (90 - 72) / 90 × 100
= 18 / 90 × 100
= 0.2 × 100
= 20%
The percentage of the delivered apples have been sold is 80% and this can be determined by using the unitary method.
Given :
A grocer reports that the store has sold 72 of the 90 boxes of apples delivered this week.
The following steps can be used in order to determine the percentage of the delivered apples that have been sold:
Step 1 - The unitary method can be used in order to determine the percentage of the delivered apples that have been sold.
Step 2 - According to the given data, 90 boxes are 100% boxes of apples.
Step 3 - Now, let the percentage of the delivered apples that have been sold be 'x'. So, the value of 'x' is:
[tex]x = \dfrac{72}{90}\times 100[/tex]
Step 4 - Simplify the above expression.
[tex]x = 80\%[/tex]
Therefore, the percentage of the delivered apples have been sold is 80%.

What is the value of b in the equation

una dintre fetele laterale ale unei piramide patrulatere regulate este triunghi echilateral cu latura de 7cm. Calculati aria bazei piramidei consideratei
Answer:
21.27 cm^2
Step-by-step explanation:
Pentru a calcula aria bazei, putem folosi formula lui Heron Matematic aceasta este;
A = √s (s-a) (s-b) (s-c)
Unde s = (a + b + c) / 2
a, b, c se referă la laturile triunghiului
A = (7 + 7 + 7) / 2 = 21/2 = 10,5
A = √10,5 (10,5-7) (10,5-7) (10,5-7)
A = √10,5 (3,5) (3,5) (3,5)
A = √450.1875
A = 21.2176 cm ^ 2, care este de aproximativ

Given f(x) = -6(4 - x), what is the value of f(-0.6)?
A)-30
B) -27.6
C) -60
D) -24.6
Step-by-step explanation:
f(x) = -6(4-x) which f(-0.6)
therefore:
we multiple -6×4= -24 and -×- =+ this implies +6×x = 6x
we add:
-24 + 6x which we already know x is = -0.6
-24 + 6 (-0.6)
-24 + 3.6
= the big number always carry the sign
the answer is = -27.6

7. Movers, Not Shakers moving company charges $800 plus $16 per hour. Hernia Movers
charges $720 plus $21 per hour.
a. After how many hours, h, would the two moving companies cost the same amount?
b. What would that amount be?
Answer:
a.16
b.1056
Step-by-step explanation:
a. So we know that Not Shakers charges 800 dollars + 16 per hour, so we can call that 800 + 16h. We also know that Hernia Movers charges 720 dollars + 21 per hour, so we can call that 720 + 21h.
Now in order to find when they will have the same amount, we have to solve for h.
Equation:
800 + 16h= 720+21h
800=720+5h
5h=80
h=16
The two companies will have the same amount after 16 hours.
b. Now we have to find that amount, so all we have to do is replace h with 16. so 720 + 21(16) = 1056.
Therefore, the amount will be 1056 dollars.

Make a table of ordered pairs for the equation.
y=−1/3x+4
Then plot two points to graph the equation.
Let's pose x as 0, 1, 2, and 3, substituting for y to receive the "ordered pairs"
y = - 1/3(0) + 4 = 0 + 4 = 4
y = - 1/3(1) + 4 = - 1/3 + 4 = - 1/7
y = - 1/3(2) + 4 = - 2/3 + 4 = 10/3
y = - 1/3(3) + 4 = - 1 + 4 = 3
