An equivalent expression in scientific notation is,
⇒ 6.45 × 10³
Option C is true.
What is Scientific notation?Scientific notation is a way of writing a very large or very small numbers. For example; 230,000,000 can be written in scientific notation as 2.3 x 10⁸.
Given that;
The expression is,
⇒ (4.5×10²) + (6.0×10³)
Now, We can simplify the expression as;
⇒ (4.5×10²) + (6.0×10³)
⇒ (4.5×10²) + (60×10²)
⇒ (4.5 + 60) × 10²
⇒ 64.5 × 10²
⇒ 6.45 × 10³

The rectangle below has an area of x^2-7x+10square meters and a width of x - 5 meters. What expression represents the length of the rectangle below? length=_____ meters.
Answer:
L = (x - 2) meters
Step-by-step explanation:
The area of the rectangle = (x² - 7x + 10) m²
The width = (x - 5) m
length = ?
Area of a rectangle = length × width
x² - 7x + 10 = L(x -5)
note L = length
divide both sides by (x-5)
(x² - 7x + 10)/(x - 5) = L
L = x² - 7x + 10 / (x -5)
Factorize x² - 7x + 10
find the numbers you can multiply to give you 10 and also add to give you -7
The numbers are -2 and -5. Therefore,
x² - 2x - 5x + 10 = 0
x(x - 2) - 5(x - 2) = 0
(x-5)(x-2) = 0
Let us go back to our division
L = x² - 7x + 10 / (x -5)
x² - 7x + 10 = (x-5)(x-2)
L = (x-5)(x-2) / (x -5)
L = (x - 2) meters
the quotient of a number and 3 is 8
Answer:
The number is 24
Step-by-step explanation:
The quotient is the answer of a division problem. If a number is divided by 3 and the answer is 8, then the number would be 24. You could set it up into an equation.
x/3=8
then you multiply both sides by 3 and you will get
x=24
The quotient is indeed the number generated by dividing one integer by the other. Whenever a fraction is simplified, the division is the whole amount that results.
The quotient is the solution to a division issue. Whenever a number is divided by three and the answer is eight, the amount is twenty-four.Calculation of the equation:
[tex]\to \bold{\frac{x}{3}=8}\\\\\to \bold{x=8\times 3} \\\\\to \bold{x=24}[/tex]
Therefore, the final answer is "24".

Analyze Leslie’s work. Is she correct? If not, what was her mistake?
Yes, she is correct.
No, the radius is twice the diameter, so she needed to multiply by two instead of dividing.
No, the value of 62 is 6 times 2, or 12.

Find the 96th term of the arithmetic sequence
-3, -14, -25, ...
Answer:
-1059
Step-by-step explanation:
Katelyn, this is super easy to understand.
Anyways, to find the 96th term of the sequence, first subtract -14 and -3. You may be thinking it is -17, but it is not. -17 is only if you are subtracting -14 and 3.
(-14) - (-3) = -14 + 3 = -11.
That means the difference between each number is -11.
Now all you have to do is take the -11 and multiply it by 96, which is -1056. Then, add the -1056 to -3, which is -1059. That should be your answer.

Each brick is 13 inches long,5 inches wide,and 4 inches tall.of they used 11,700in3 of concrete how many Bricks did they make.
Answer:
45 bricks
Step-by-step explanation:
- With the knowledge of the 11,700 in^3 being used. We would need to have the measurements of the brick in that form as well. So in order to find the volume, we must multiply all sides. (13*5*4) = 260 in^3
- Now we have both numbers, we can just divide 11,700 by 260. This will give us 45. Meaning that 45 bricks are made.

Juliet is standing on the balcony 44 above the ground. She is looking at Romeo at an angle of depression of 6 degrees. if both star-crossed lovers were holding the end of a strong, what would the length of the string be?
Answer:
length of string ≈ 421 units (nearest whole number)
Step-by-step explanation:
Juliet is standing on the balcony 44 above the ground . The angle of depression is 6°. A string was held between Juliet and Romeo.
The illustration forms a right angle triangle. The hypotenuse of the triangle is the length of the string held by both star crossed lovers. The opposite side of the triangle is given as 44. Therefore,
using sin ratio
sin 6° = opposite/hypotenuse
sin 6° = 44/length of string
cross multiply
length of string sin 6° = 44
divide both sides by sin 6°
length of string = 44/sin 6°
length of string = 44/0.10452846326
length of string = 420.937978274
length of string ≈ 421 units(nearest whole number)

The value of a car is $23,000. It loses 11% of its value every year. Find the approximate monthly decrease in value. Round your answer to the nearest tenth.
Answer:
$210.8 monthly.
Step-by-step explanation:
There are two ways to do this. You can either find out what 11% of $23,000 is by multiplying .11 by $23,000, then subtract this from $23,000 to find the yearly increase, where you can then divide by 12, or you can divide .11 by 12 and then multiply this by $23,000. I did the former and got $210.8 as an answer.

Tony need 16 inch long pieces of gold chain to make each 3 necklaces. He has a peice of chain that is 4 1/2 long. How much chain will he have left after making the necklaces
Answer: 6 inches of chain will he have left after making the necklaces
Step-by-step explanation:
There is a missing information. The correct question is:
Tony needs 16-inch pieces of gold chain to make each of 3 necklaces. He has a piece of chain that is 4 1/2 feet long. How much chain will he have left after making the necklaces.
Solution
We would convert 4.5 feet to inches
1 foot = 12 inches
4.5 feet = 4.5 × 12 = 54 inches
Tony needs 16-inch pieces of gold chain to make each of 3 necklaces. It means that the number of the 16 inches pieces of gold chain that can be gotten to make each of 3 necklaces necklaces is 16 × 3 = 48
The length of chain left chain that will he have left after making the necklaces is
54 - 48 = 6 inches

Find m angle d for m angle b = 65
The figure is not drawn to scale
Answer:
Denote O as center of circle, draw OA, OC.
As property of tangent line from outside of circle (angle OAD = angle OCD = 90 deg):
=> AOC + D = 180
Moreover, angle AOC = 2 x angle B = 2 x 65 = 130
=> D = 180 - 130 = 50 deg
Hope this helps!

The measure of the angle d for m angle b = 65 in the figure of circle and quadrilateral is 50 degrees. Option A is correct.
What is a measure of angle?The measure of angle between the two points of a ray or line is the measure of rotation between these two points. The angles are measured in degrees or radians.
The figure given in the problem contained a circle and a quadrilateral.
In this figure, the measure of the angle b is,
[tex]m\angle d =65^o[/tex]
Here, the two tangent lines AD and DC cuts the circle at point A and C respectively.
Let the center of the circle is O. Thus the angle b is equal to the angle AOC by the tangent line theorem as,
[tex]\angle O =2m\angle b=130 ^o[/tex]
The sum of angle AOC and the angle D is equal to 180 degrees. Therefore,
[tex]\angle AOC+m\angle d=180\\130++m\angle d=180\\m\angle d=180-130\\m\angle d=50^o[/tex]
Hence, the measure of the angle d for m angle b = 65 in the figure of circle and quadrilateral is 50 degrees. Option A is correct.

Answer:
(B)
Step-by-step explanation:
We have the equation:
[tex]y-3=-2(x+5)[/tex]
Convert into Slope Intercept Form:
[tex]y-3=-2(x+5)[/tex]
[tex]-2*x=-2x\\-2*5 = -10[/tex]
[tex]y-3=-2x-10[/tex]
[tex]y-3+3=-2x-10+3\\\boxed {y=-2x-7}[/tex]
Slope-intercept form is [tex]y=mx+b[/tex].
Since '-7' is in the 'b spot', the y-intercept of the line would be -7, or option B.
Option B should be the correct answer.
Answer:
y intercept is -7
Step-by-step explanation:
y - 3 = -2 (x+5)
This is point slope form
We want to get this to slope intercept form
y=mx+b where m is the slope and b is the y intercept
Distribute
y-3 = -2x-10
Add 3 to each side
y-3+3 = -2x-10+3
y = -2x-7
The slope is -2 and the y intercept is -7
