Given:
The sides of the right triangular base measures 9 cm, 12 cm and 15 cm.
The height of the prism is 20 cm.
To find:
The surface area of a triangular prism.
Solution:
We know that, the area of a triangular prism is
[tex]A=P\times h[/tex]
Where, P is the perimeter of the triangular base and h is the height of the prism.
The sides of the right triangular base measures 9 cm, 12 cm and 15 cm. So, the perimeter of the right triangular base is
[tex]P=9+12+15[/tex]
[tex]P=36[/tex]
Now, the area of the triangular prism is
[tex]A=36\times 20[/tex]
[tex]A=720[/tex]
Therefore, the surface area of a triangular prism is 720 square centimetres.

Cody's fence must have sides that are twice as long as the sides of his neigbore fence. His neigbors fence contains an area of 887.5 ft the length of the fence is
Answer: 59.58 ft
Step-by-step explanation:
Given
The area of the neighbor's fence is [tex]A=887.5\ ft^2[/tex]
Suppose the length of the fence is L and the shape of the fenced area is square
So, we can write
[tex]\Rightarrow L^2=887.5\\\Rightarrow L=\sqrt{887.5}=29.79\ ft[/tex]
According to the question, Cody's fence length must be twice of neighbor's
The length of Cody's fence is [tex]=2L=2\times 29.79=59.58\ ft[/tex]

Answer:
4.8 Liters
Step-by-step explanation:
Sundaes at her next birthday party. She thinks each person will eat 200 milliliters of ice cream, and there will be 24 people at her party. How many liters of ice cream should she buy
Step 1
1 person = 200ml of ice cream
24 persons = x
Cross Multiply
x = 24 × 200ml of ice cream
x = 4800 ml of ice cream
Step 2
How many liters of ice cream should she buy
We convert from Milliliters to Liters
1 milliliters= 0.001 liters
4800 millilitres = x
Cross Multiply
= 4800 × 0.001 liters
= 4.8 Liters
Therefore, she should buy 4.8 Liters of ice cream

facrorise 2x^2- x- 1
please explain..
Answer:
(x - 1)(2x + 1)
Step-by-step explanation:
Given
2x² - x - 1
Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.
product = 2 × - 1 = - 2 and sum = - 1
The factors are - 2 and + 1
Use these factors to split the x- term
2x² - 2x + x - 1 ( factor the first/second and third/fourth terms )
2x(x - 1) + 1 (x - 1) ← factor out (x - 1) from each term
= (x - 1)(2x + 1) ← in factored form

The measure of an angle is 119°. What is the measure of its supplementary angle?
Answer:
The supplement of 61° is 119°
Step-by-step explanation:
180 - 61 = 119° The supplement of 61° is 119°
The measure of the angle is 61 degrees
How to determine the angleTo determine the measure of the angle, we need to know the following;
Supplementary angle are angles that sum up to 180 degreesComplementary angles are angles that sum up to 90 degreesAlternate angles are equalCorresponding angles are equalAngles on a straight line is equal to 180 degreesFrom the information given, we have that;
The measure of an angle is 119°'
This is represented as;

8 Rotate the point (-3,-4) around the origin 180 degrees. State the image of the point.
A (-4,-3)
B (-4,3)
C (4, -3)
D (3, 4)
Answer: D (3,4) trust and believe
brainlyst pls I think I spelt is wrong
Step-by-step explanation:
When a line or shape or point is rotated, it must be rotated around a point.
The image of the point is D. (3,4)
The point is given as:
[tex]\mathbf{(x,y) = (-3,-4)}[/tex]
A 180-degree rotation across the origin is represented as:
[tex]\mathbf{(x,y) \to (-x,-y)}[/tex]
Substitute values for the coordinates of the point (x,y)
[tex]\mathbf{(-3,-4) \to (-(-3),-(-4))}[/tex]
Simplify
[tex]\mathbf{(-3,-4) \to (3,4)}[/tex]
Hence, the image of the point is D. (3,4)
