Answer:
The value is 4
Step-by-step explanation:
This is because the value of an absolute number is always positive so the absolute value of 4 would remain 4.
Answer:
Step-by-step explanation:
The expression that we have to factorize in this problem is
And we have to factorize it by grouping.
First of all, we start by factorize a factor from the first two terms, we get:
Then we factorize a term -3 from the last two terms, and we get:
Now we can group the similar terms, and we get:
So the correct option is option D, the last one.
Answer:
n = -15/8
Step-by-step explanation:
You can transform this into an easier equation by performing cross-multiplication:
(ie. topleft times bottomright = bottomleft times topright)
so n = -30/16 = -15/8
Answer: (a) 80cm³ (b) 4618.14 m³
Question A
The figure is made up of a cubiod and a triangular prism.
1. Find the volume of the <span>cubiod.
</span>2. Find the volume of the triangular prism.
3. Add the two volume up to find the volume of the figure
--------------------------------------
Area of the cuboid
--------------------------------------
Volume = Length x Width x Height
Volume = 4 x 5 x 2
Volume = 40 cm³
--------------------------------------
Area of the triangular prism
--------------------------------------
Height = 6 - 2 = 4cm
Volume = 1/2 x base x height x Length
Volume = 1/2 x 4 x 4 x 5
Volume = 40 cm³
--------------------------------------
Volume of the figure
--------------------------------------
40 + 40 = 80 cm³
--------------------------------------
Answer: 100 cm³
--------------------------------------
Question B
Volume of the cylinder = πr²h
Volume of the cylinder = π x (14)² x 7.5
Volume of the cylinder = 4618.14 m³
--------------------------------------
Answer: 4618.14 m³
