Answer:
2000
Hope this helps :)
Step-by-step explanation:
Since the exponent of the scientific notation is positive, move the decimal point 3 places to the right.
The standard notation of the expression is 2 x 10³ is 2000.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
2 x 10³
Standard notation means writing an expression without any base and exponents.
Now,
10³ can be written as 1000.
So,
2 x 10³
= 2 x 1000
= 2000
Thus,
The standard notation is 2000.

Speedie ran the 200 meter race in 25.5 seconds. How much of an hour did it take Speedie to run
the race? 1.0 hour = 3600.0 seconds
Answers
Answer:
Speedie ran the race in 0.708(3)% of an hour, the 3 in the parentheses means the 3 repeats forever
Step-by-step explanation:
We have 25.5/3600, and when we convert it to a decimal, we have 0.00708(3), the 3 in the parentheses means the 3 repeats forever. To convert it to percentage, we multiply it by 100, to get 0.708(3). Hope it helps!

Jasmine paid $64.50 for a bracelet, after tax, and the tax rate is 7.5%. What was the original price of the bracelet?
Answers
Answer:
About $59.66
Step-by-step explanation:
To find the amount of tax was paid, multiply 64.50 by 0.075 (because 0.075 = 7.5%). This would be 4.8375, which when rounded is 4.84. You subtract 64.50 by 4.84 to get 59.66, but because I rounded, it is about $59.66.
Answer:
60
Step-by-step explanation:
First, change the percentage to a decimal and write the equivalence of the sales tax amount. Let x be the original cost of the item.
Sales tax amount =x⋅0.075
Next, substitute the value into the equation:
Original Cost + Sales Tax Amount = Total Cost
x+0.075x=64.50
Add like terms.
1.075x=64.50
Divide both sides by 1.075 to isolate the unknown value.
x=$60

9x+2y=-10
Explanation:
First, we would need to organize the information given into slope-intercept form.
Slope-intercept form: y=mx+b
Here’s what the variables mean:
Y=the y coordinate
M=the slope
X=the x coordinate
B=the y-intercept (the point on the line that intercepts the y-axis)
When a linear equation in slope-intercept form is complete, the x and y variables are left just as they are. Knowing this, we just have to plug in the values given for the coordinate and solve for b, the y-intercept.
(-2,4),
y=mx+b
4=m(-2)+b
4=-2(-9/2)+b
4=9+b
Subtract 9 on both sides
4-9=9+b-9
-5=b
Awesome! Now, we know that the equation in slope-intercept form is:
y=-9/2x-5
To organize it into standard form, we need to move some things around.
Standard form: Ax+By=C
(A, B and C don’t have any kind of direct interpretation on a graph.)
y=-9/2x-5
Move the x variable to the other side
9/2x+y=-9/2x-5+9/2
9/2x+y=-5
It may look like we’ve finished here, but A, B and C need to be integers, meaning we cannot have any fractional values in these places.
9/2x+y=-5
Multiply both sides by 2 since it is the denominator
9x+2y=-10

The graph of the reciprocal parent function f(x)=1/x, is shifted 6 units down and 1 unit to the right to create the graph of g(x). What function is g(x)?
A. g(x)=1/x+6-1
B. g(x)=1/x-1-6
C. g(x)=1/x-6-1
D. g(x)=1/x+1-6
Answers
Transformations are used to move a function from one position to another. The new function g(x) is [tex]g(x) = \frac{1}{x-1} - 6[/tex]
Given that
[tex]f(x) = \frac 1x[/tex]
When shifted 6 units down. the rule of transformation is:
[tex](x,f(x)) \to (x,f(x) - 6)[/tex]
So, we have:
[tex]f'(x) = f(x) - 6[/tex]
[tex]f'(x) = \frac 1x - 6[/tex]
When shifted 1 unit left. the rule of transformation is:
[tex](x,g(x)) \to (x -1,f'(x))[/tex]
So, we have:
[tex]g(x) = f'(x - 1)[/tex]
[tex]g(x) = \frac{1}{x-1} - 6[/tex]
Hence, the new function g(x) is [tex]g(x) = \frac{1}{x-1} - 6[/tex]

Answers
Answer: (z + 2)(z - 3)
Step-by-step explanation:
First, we have 1 as a coefficient on z², so we multiply that by -6, which gives us -6. Now we must find out what two numbers when multiplied, give us -6, and when added together, give us -1 (z's coefficient). Going through -6's factors, I got -3 and 2 since we need a negative one when they are added together. Now we can input our values:
(z - 3)(z + 2).
Double checking, we get the starting equation, which means our factorization was correct, and so is the solution.
Note: it does not matter which binomial comes first because you will get the same answer regardless of its position.
A car with a mass of 1,250 kg travels at 2.24 m/s and bumps into a stopped car with a mass of 1,300 kg. After the collision, the two cars stick together and move forward. How fast will they both move forward? Round your answer to two decimal places.
0.57 m/s
0.55 m/s
1.10 m/s
1.14 m/s
Answers
Answer:
1.10
Step-by-step explanation:
The velocity of the combined cars after the collision is 1.10 m/s.
What is the velocity?Velocity is defined as the displacement of the object in a given amount of time and is referred to as velocity.
The momentum of an object is equal to its mass multiplied by its velocity.
The first car has a mass of 1,250 kg and a velocity of 2.24 m/s, its momentum is 1,250 kg x 2.24 m/s = 2,800 kgm/s.
Similarly, since the second car has a mass of 1,300 kg and a velocity of 0 m/s (it is stopped), its momentum is 0 kgm/s.
Therefore, the total momentum of the two cars before the collision is:
⇒ 2,800 kgm/s + 0 kgm/s = 2,800 kg m/s.
After the collision, the two cars stick together and move forward as one unit. We can find the velocity of the combined cars by dividing their total momentum by their total mass.
The total mass of the cars is:
⇒ 1,250 kg + 1,300 kg = 2,550 kg.
So, the velocity of the combined cars after the collision is:
⇒ 2,800 kgm/s / 2,550 kg = 1.098 kgm/s.
To two decimal places, this velocity is 1.10 m/s. Therefore, the correct answer is 1.10 m/s.

Every week I buy four 2-litre bottles of lemonade whilst shopping at my local supermarket. Last week the bottles on the shelf were limited edition “2.5 litres for the price of 2 litres” bottles, and the supermarket also had a “buy 3 bottles, get another one free” offer.
In terms of cost per litre, by what percentage was the cost of my four bottles of lemonade lower than usual last week?
Answers
Answer:
40%
Step-by-step explanation:
Every week you he buys 4 number of 2 Litres bottle of lemonade.
Thus, let's say cost of each bottle is X.
This means he total cost is 4X
Now, total litres = 4 × 2 = 8 litres
Thus, cost per litre = 4X/8 = ½X
Now, we are told that Last week the bottles on the shelf were limited edition “2.5 litres for the price of 2 litres” bottles ".
This means that now, it is cheaper.
However, the supermarket also had a “buy 3 bottles, get another one free” offer.
Now since he buys 8 litres weekly, now since it's 2.5 L bottle, he will buy 3 since he will be given 1 free for every 3 he buys.
Thus, total litres he is paying for = 2.5 × 3 = 7.5 litres
Thus, cost per bottle is; 3X
Since he is getting 1 bottle free, then total bottle he gets is; 7.5 L + 2.5 L = 10L
Thus;
cost per litre is now; 3X/10
Difference in costs per litre is;
½X - 3X/10 = X/5
percentage of the cost of four bottles of lemonade lower than usual last week = (X/5)/(½X) × 100% = 2/5 × 100% = 40%

Five girls and two boys are standing in a line randomly. What is the probability that two boys are next to each other?
Answers
========================================================
Explanation:
Let's say the teacher pulls the two boys out of the line, and stands in their place. So we have 5 girls and 1 teacher making 6 people total.
There are 6! = 6*5*4*3*2*1 = 720 different permutations here. Order matters. This involves the teacher, so let's have him/her step out of the line and have the two boys replace the teacher's position. This guarantees the boys stick together. For any permutation, we have 2 different ways to arrange the boys. So we have 2*720 = 1440 different ways to arrange the students so that the two boys are next to each other.
This is out of 7! = 7*6*5*4*3*2*1 = 5040 different permutations overall (we're arranging 5 girls+2 boys = 7 people).
The probability we're after is going to be 1440/5040 = 2/7
--------
Or you could see it like this
1440 = 2*6!
5040 = 7! = 7*6!
So,
1440/5040 = (2*6!)/(7*6!)
1440/5040 = 2/7
How many solutions to the equation: 3x + 5 = 3x - 7
Answers
Answer:
Step-by-step explanation:
Simplifying
3x + 5 = 3x + 7
Reorder the terms:
5 + 3x = 3x + 7
Reorder the terms:
5 + 3x = 7 + 3x
Add '-3x' to each side of the equation.
5 + 3x + -3x = 7 + 3x + -3x
Combine like terms: 3x + -3x = 0
5 + 0 = 7 + 3x + -3x
5 = 7 + 3x + -3x
Combine like terms: 3x + -3x = 0
5 = 7 + 0
5 = 7
Solving
5 = 7
