A right-angled triangle has an area of
45 cm².
The width of the triangle is n + 3 cm.
The height is 9 cm less than the width.
45 cm²
n + 3
Find the value of n.
n =
Answer:
A = 1/2 width × height
width = n + 3 cm
height = width - 9 cm
height = n + 3cm - 9cm
height = n - 6cm
A = 1/2 width × height
= 1/2 (n + 3cm) × (n - 6cm)
45cm^2 ×2 = n^2 - 3ncm - 18cm^2
n^2 - 3ncm - 18cm^2 - 90cm^2 = 0
n^2 - 3ncm - 108cm^2 = 0
Find two numbers that their sum is -3 and their product is 108. Therefore, the numbers could be -12 and 9
n^2 - 3ncm - 108cm^2 = 0
n^2 - 12ncm + 9ncm - 108cm^2 = 0
n(n - 12cm) + 9cm(n - 12cm) = 0
(n - 12cm) (n + 9cm) = 0
Either (n - 12cm) = 0 or (n + 9cm) = 0
n = 12cm or n = -9cm
but n = -9cm is invalid because there is no negative distance.
n = 12cm is the answer

The expression is not factorable with rational numbers.
Except if you made a typo in your equation and it's x^2-4x-12
calculation:
-6x2=12

how to solve 4.56x1,000
Answer:
4560
Step-by-step explanation:
There are 3 zeros in 1000. If you are multiplying, move the decimal place over however many places to the right that there are zeros. For example,
4.56 x 1000
45.6 x 100
456 x 10
4560 x 1
We moved the decimal place to the right one every time we removed a zero.
This method is extremely useful for multiplying by 1, 10, 100, etc.
Hope this helps!
(This method is an easy yet complicated way to multiply by)

James and Michael are the partners in a local business. They needed $480,000 to start the
business. They invested in the ratio 1:2, respectively. How much did James invest?
$140,000
$150,000
$160,000
$170,000
Answer:
James invested $160,000
Step-by-step explanation:
- In total, they needed $480,000 to start the business
- 1:2 ratio means one of them payed double the amount than the other
so the expression would be,
2x + x = 480,000
Let x represent how much they each need to invest
the expression can be simplified to,
3x = 480,000
now you need to get x alone, this would be done be dividing both sides by 3
[tex]\frac{3x}{3} = \frac{480,000}{3}\\x = 160,000[/tex]
James invest $160,000
Michael invest $160,000 x 2 = $320,000
and if you add them together, you get the total amount
$320,000 + $160,000 = $480,000

Answer:
Step-by-step explanation:
The equilateral triangle shown is rotated about line a. each side of the triangle measures 20 mm. an equilateral triangle is shown. line of rotation a goes through one point and the midpoint of the opposite side. what shape is created by the rotation and what is the approximate circumference of the base? circumference of a circle: c = 2πr a cylinder with a circumference of about 63 mm a cylinder with a circumference of about 126 mm a cone with a base circumference of about 63 mm a cone with a base circumference of about 126 mm
The circumference of the circle based on the equilateral triangle is 63mm.
How to calculate the circumference?The side of the triangle is 20mm. The radius will be:
= 20/2 = 10
The circumference of the circle will be:
= 2πr
= 2 × 3.14 × 10
= 63
In conclusion, the circumference is 63mm.

Answer:
a cone with a circumference of about 63 mm
Step-by-step explanation:
By imagining the triangle rotating around the line in the middle, we can see that the triangle will create a cone, not a cylinder.
If one side of the triangle measures 20 mm, then the radius at the base of our cone will be 10 mm. (20 mm is the diameter and the radius is half of that.)
Use 2πr to solve for the circumference and it comes out to 63.
Thus, the rotated triangle will created a cone with a base circumference of about 63 mm.
Factor the algebraic expression.

What is the slope of the line through the points (-2, -1) and (4, 3)?
Ans: 2/3
Step-by-step explanation:
Formula : [tex]m = \frac{y2 - y1}{x2- x1}[/tex] (Then replace the number in )
= 3- (-1) / 4 - (-2) = 4 / 6 = 2 / 3
Step-by-step explanation:
the slope is always the ratio "y coordinate change / x coordinate change" when going from one point on the line to another.
so, when going from (-2, -1) to (4, 3)
x changes by +6 (from -2 to 4).
y changes by +4 (from -1 to 3).
therefore, the slope is
+4/+6 = 4/6 = 2/3
The radius is 10 units, and each layer is one unit high. What is the volume of the cylinder in cubed units?
Answer:
Volume of cylinder is 6285.71 square units.
Step-by-step explanation:
Given the radius of cylinder 10 units. The height is twice its radius. we have to find its volume.
r=10 units
⇒ Diameter, d = 20 units
Also given height is twice its radius.
⇒ Height=2(r)=2(10)=20 units
Volume of cylinder=πr^2h= 22/7 × 100×20
=22/7 × 2000
= 44000/7
= 6285.71square units.
hence, volume of cylinder is 6285.71 square units.
