(Hurry giving brainliest) Which idea does Arnold need to correct? In specular reflection, reflected rays move in the same direction. In scattering, light strikes particles in the atmosphere. In diffuse reflection, reflected rays move in different directions. In scattering, long wavelengths are scattered the most.
Answer:
D. In scattering, long wavelengths are scattered the most.
Step-by-step explanation:
Scattering of light is the effect observed when there is an interaction between light energy and some particles. This occurs often in the earth's atmosphere which consists of different sizes of particles that interacts with the sunlight.
In scattering, light of shorter wavelengths are scattered by small sized particles compared to those with longer wavelengths. Example is the scattering of the sunlight by the atmospheric particles where colors with short wavelengths are scattered the most.
Arnold need to correct the statement; In scattering, long wavelengths are scattered the most. To read; In scattering, short wavelengths are scattered the most.

6 – x + = 6 minus StartFraction 3 Over 4 EndFraction x plus StartFraction 1 Over 3 EndFraction equals StartFraction one-half EndFraction x plus 5.X + 5 2 3 6 12
Answer:
x = 16/15
Step-by-step explanation:
Given:
6 - 3/4x + 1/3 = 1/2x + 5
Collect like terms
6 + 1/3 - 5 = 1/2x + 3/4x
(18+1-15)/3 = (2x+3x)/4
4/3 = 5/4x
x = 4/3 ÷ 5/4
x = 4/3 × 4/5
x = (4 * 4) / (3 * 5)
x = 16/15
If a 750 ml bottle of juice costs £1.90 and a 1 litre bottle of the same juice costs £2.50 then the 750 ml bottle is better value.
Answer:
The 1 liter bottle is better value
Step-by-step explanation:
Cost of 750 ml = £1.90
Cost of 1 liter = £2.50
1000 ml = 1 liter
Cost per 250 ml
750 ml / 3 = £1.90 / 3
250 ml = £0.6333333333333
Approximately,
£ 0.633
Cost per 250 ml
1 liter / 4 = £2.50 / 4
250 ml = £0.625
The 750 ml bottle is not a better value
The 1 liter bottle is better value
Which of the following is the solution to the equation x + 8.6 = 36.2?
10.4
17.2

44.8
Answer:
27.6
Step-by-step explanation:
x+8.6=36.2
Subtract 8.6 from both sides.
x=36.2-8.6
Subtract 8.6 from 36.2 to get 27.6.

The length of a rectangular-shaped patio is 3 feet shorter than four times its width.
A. Write an equation to represent the area of the patio.
B. If the patio has an area of 370ft square, find the dimensions of the patio
Answer:
A. A = 4x² – 3x
B. Dimension = 37 ft × 10 ft
Step-by-step explanation:
A. Writing an equation to represent the area of the patio.
From the question given above,
Length (L) = (4x – 3) ft
Width (W) = x ft
Area (A) =?
Area of a rectangle is given by:
Area (A) = Length (L) × Width (W)
A = L × W
A = (4x – 3)x
Clear bracket
A = 4x² – 3x
B. Determination of the dimensions of the patio.
Area (A) = 370 ft²
Dimensions =?
Next, we shall determine the width and length. This can be obtained as follow:
From (A) above,
A = 4x² – 3x .... (1)
A = 370 ....... (2)
Equating equation 1 and 2, we have
4x² – 3x = 370
Rearrange
4x² – 3x – 370 = 0
Solving by formula method:
4x² – 3x – 370 = 0
Coefficient of x² (a) = 4
Coefficient of x (b) = –3
Constant (c) = –370
x = –b ± √(b² – 4ac) / 2a
x = –(–3) ± √(–3² – (4×4×–370)) / 2×4
x = 3 ± √(9 + 5920) / 8
x = 3 ± √(5929) / 8
x = 3 ± 77 / 8
x = (3 + 77) / 8 or (3 – 77) / 8
x = 80/8 or –74/8
x = 10 or –37/4
Since measurement can not be negative, thus,
x = 10
Width (W) = x ft
x = 10
W = 10 ft
Length (L) = 4x – 3 ft
x = 10 ft
L = 4(10) – 3
L = 40 – 3
L = 37 ft
Finally, we shall determine the dimensions. This is illustrated below:
W = 10 ft
L = 37 ft
Dimension =?
Dimension = L × W
Dimension = 37 ft × 10 ft
juans pencil box measures 6 cm long. if the length of the diagonal is 10 cm what is the width of the pencil box
Answer:
8 cm
Step-by-step explanation:
We can use the Pythagorean theorem to solve since we have a right triangle
a^2 +b^2 = c^2 where a and b are the legs and c is the hypotenuse
a^2 +6^2 = 10^2
a^2 +36 = 100
a^2 = 100-36
a^2 = 64
Taking the square root of each side
sqrt(a^2) = sqrt(64)
a =8
Answer:
8 cm
Step-by-step explanation:
Use the Pythagorean theorem- [tex]a^{2} +b^{2} =c^{2}[/tex]
leg a: 6cm
leg b: unknown
hypotenuse: 10cm
Therefore [tex]6^{2} +x^{2} =10^{2} = 36+x^{2} =100[/tex]
Subtract 36 to 100 to isolate the [tex]x^{2}[/tex]. [tex]x^{2} =64[/tex]
Square root both sides and get your answer of 8cm

Answer:
A.]A chord of a circle of diameter 40 cm subtends an angle of 70° at the centre of the circle.
Solution given;
diameter [d]=40cm
centre angle [C]=70°
(a) Find the perpendicular distance be tween the chord and the centre of the circle.
Answer:
we have
the perpendicular distance be tween the chord and the centre of the circle=[P]let
we have
P=d Sin (C/2)
=40*sin (70/2)
=22.9cm
the perpendicular distance be tween the chord and the centre of the circle is 22.9cm.
(b) Using = 3.142, find the length of the minor arc.
Solution given;
minor arc=[tex]\frac{70}{360}*πd=\frac{7}{36}*3.142*40[/tex]

the length of the minor arc. is 24.44cm.
B.]In the diagram, XZ is a diameter of the cir cle XYZW, with centre O and radius 15/2 cm.
If XY = 12 cm, find the area of triangle XYZ.
Solution given:
XY=12cm
XO=15/2cm
XZ=2*15/2=15cm
Now
In right angled triangle XOY [inscribed angle on a diameter is 90°]
By using Pythagoras law
h²=p²+b²
XZ²=XY²+YZ²
15²=12²+YZ²
YZ²=15²-12²
YZ=[tex]\sqrt{81}=9cm[/tex]
:.
base=9cm
perpendicular=12cm
Now
Area of triangle XYZ=½*perpendicular*base
=½*12*9=54cm²
the area of triangle XYZ is 54cm².
Answer:
Question 1a)
d = 40 cm ⇒ r = 20 cm
Let the perpendicular distance is x.
Connecting the center with the chord we obtain a right triangle with hypotenuse of r and leg x with adjacent angle of 70/2 = 35°.
From the given we get:
x/20 = cos 35°x = 20 cos 35°x = 16.383 cm (rounded)b)
The minor arc is 70° and r = 20
The length of the arc is:
s = 2πr*70/360° = 2*3.142*20*7/36 = 24.437 cm (rounded)Question 2Since XZ is diameter, the opposite angle is the right angle, so the triangle XYZ is a right triangle.
r = 15/2 cm ⇒ XZ = d = 2r = 2*15/2 = 15 cmFind the missing side, using Pythagorean:

This drawing would be a step in finding which point of concurrency in a triangle?
Answer:
B. Orthocenter
Step-by-step explanation:
The orthocenter of a triangle is the point of intersection of the three altitudes (the perpendicular from a vertex to the side facing the vertex) of a triangle
The steps used in constructing the orthocenter includes the steps for drawing of the perpendicular to the sides of the triangle from a point which is the vertex opposite the side of the triangle
Therefore, in the given diagram, a perpendicular to the side KS is drawn from the (vertex) point W, by drawing an arc with center at W that intersects the side KS at two points. Rom the points of intersection of the arc drawn from W intersects KS, with the compass, two arcs are drawn to intersect at a point from which a line drawn to W, is perpendicular to KS
Therefore;
The correct option is B. orthocenter
Determine the period
Answer:
3 units
Step-by-step explanation:
The period of a wave is the time taken to complete a cycle of motion of the wave
In the given figure, the graduations of the x-axis, which is the usually time axis = 1 unit
At the origin, (0, 0), the vertical displacement of the wave = 0
The maximum value of the wave function is between x = 0 and x = 1
The minimum value of the wave function is between x = 2 and x = 3
At the point (3, 0) the value of the wave function is again 0, and a cycle of the wave is completed
Therefore, the period of the wave = 3 units of the x-variable
