denzel wants to work out the density,in g/cm cubed, of a block of wood,The block of wood is in the shape of a cuboid.His measurements are
length 17.7cm
width of 8.3cm and
height 13.0cm .]
He also measured the mass at 2090g.By considering bounds,work out the density of the wood.Give your answer to a suitable degree of accuracy Show all your working and give full reason for your answer
Answer:
Density of cuboid box = 1.09 g/cm cubed
Step-by-step explanation:
Given that:
Length of cuboid box = 17.7 cm
Width of box = 8.3 cm
Height of box = 13.0 cm
Mass of box = 2090 grams
Density = Mass/Volume
We will find the volume first.
Volume of box = Length * Width * Height
Volume of box = 17.7 * 8.3 * 13.0 = 1909.8 cm cubed
Density = [tex]\frac{2090}{1909.8}[/tex]
Density = 1.09 g/cm cubed
Hence,
Density of cuboid box = 1.09 g/cm cubed

Answer:
x=8
KN=24
LK is congruent to LM
LN is congruent to NL
Answer: x = 8
MN = 52
LK is congruent to LM
LN is congruent to NL
ΔKLN and ΔMLN have:
LN ≅ LN
∠K = ∠M = 90°
∠KLN = ∠MLN
=> ΔKLN ≅ ΔMLN
=> KN = MN
=> 7x -4 = 5x + 12
⇔ 2x = 16
⇔ x = 8
=> KN = MN = 7.8 - 4 = 52

P, Q, and R form the vertices of a triangle. QR = 7.8 RP = 15.7 and PQ = 11.6 Find the angle PRQ rounded to 1 DP
Answer:
45.1°
Step-by-step explanation:
A triangle is a polygon with three sides and three angles. The types of triangles are scalene triangle, equilateral triangle, right angled triangle and obtuse triangle.
Cosine rule states that given a triangle with sides a, b, c and their corresponding angles opposite to the sides as A, B, C. Then:
[tex]a^2=b^2+c^2-2bc*cosA\\[/tex]
Given triangle PQR, let ∠PQR = x, to find angle PQR, we use cosine rule:
[tex]PQ^2=QR^2+RP^2-2(QR)(RP)*cos(x)\\\\substituting:\\\\11.6^2=7.8^2+15.7^2-2(7.8)(15.7)cos(x)\\\\134.56=60.84+246.48-244.92cos(x)\\\\244.92cos(x)=60.84+246.48-134.56\\\\244.92cos(x)=172.76\\\\cos(x)=0.7054\\\\x=cos^{-1}(0.7054)\\\\x=45.1^o[/tex]
x = ∠PQR = 45.1°

What is Composition of functions?
Evaluation of a function at the value of another function is known as Composition of function. A function composition is a process in which two functions, f and g, form a new function, h, in such a way that h(x) = g(f(x)). This signifies that function g is being applied to the function x. So, in essence, a function is applied to the output of another function.
Given data ,
Let the equation for the function f ( x ) = x + 3
Let the equation for function g ( x ) = 2x² + 3
Now , the composition of function is calculated by
( f . g ) ( x ) = f ( x ) . g ( x )
So , the equation for the new composed function will be
( f . g ) ( x ) = ( x + 3 ) ( 2x² + 3 )
= 2x³ + 6x² - 4x - 12
Therefore , the value of ( f . g ) ( x ) is 2x³ + 6x² - 4x - 12
Hence , the composition function ( f . g ) ( x ) is 2x³ + 6x² - 4x - 12

7 Tacos and 3 burritos cost $22
3 tacos and 1 burrito cost $8
Define x and y:
Write a system (2) equations to model the
situation:
What is the cost of a taco? What is the cost of
a burrito?
Answer:
System of Equations:
let x be the cost of a taco
let y be the cost of a burrito
7x + 3y = 22
3x + y = 8
The cost of a taco is $1
The cost of a burrito is $5
Step-by-step explanation:
Please let me know if you want me to add an explanation as to why this is the answer. I can definitely do that, I just wouldn’t want to write it if you don’t want me to :)
Answers:
Equations: 7x+3y=22
3x+y=8
The cost of tacos is $1 and the cost of burrito is $ 5.
Step-by-step explanation:
Let the cost of tacos be x and the cost of burrito be y.
Equations: 7x+3y=22
3x+y=8
3x+y=8, y=8-3x
sub y=8-3x into 7x+3y=22, 7x+3(8-3x)=22
-2x=-2
x=1
sub x=1 into 3x+y=8, 3(1)+y=8
y=5
∴The cost of tacos is $1 and the cost of burrito is $5.

What is Trigonometry?The area of mathematics that deals with particular angles' functions and how to use those functions in calculations. There are six popular trigonometric functions for an angle. Sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant are their respective names and acronyms (csc). T
Given :
60° angle of elevation from the ground.
Height of the monument = 555 ft.
Now, using trigonometry function
sin [tex]\theta[/tex] = P/H
sin 60 = 555/ H
√3/2= 555/ H
Hypotenuse = 640.858 ft.
Again, cos [tex]\theta[/tex] = B/H
1/2 = B/640.858
Base = 320.42 ft.
Hence, the distance between the man's feet to the base of the monument is 320.42 ft.
