Answer:
416 in²
Step-by-step explanation:
Given that:
Height. h = 4 in
Length = 12 in
Width = 10 in
The surface area of a rectangular prism is obtained using the relation :
Surface Area, S = 2(lw + lh + wh)
S = 2[(10*12) + (10*4) + (12*4))
S = 2(120 + 40 + 48)
S = 2(208)
S = 416 in²

the ratio of doors to windows is 1:5 . There are 186 doors and windows in a building . HOw many doors and windows are there?
Answer:
a. Doors = 31 doors
b. Windows =155 windows
Step-by-step explanation:
Given the following data;
Ratio D:W = 1:5 = 1 + 5 = 6
Total number of doors and windows = 186
Ratio of doors to windows = 1/6
Ratio of windows to doors = 5/6
To find the ratio of the doors;
Doors = 1/6 * 186
Doors = 186/6
Doors =31 doors
To find the ratio of windows;
Windows = 5/6 * 186
Windows = 930/6
Windows =155 windows
A highway inspector needs an estimate of the mean weight of trucks crossing a bridge on the interstate highway system. she selects a random sample of 49 trucks and finds a mean of 15.8 tons with a sample standard deviation of 3.85 tons. the 90 percent confidence interval for the population mean is:
Answer:
14.90 to 16.70 tons
Step-by-step explanation:
We are given;
Sample size; n = 49
Mean; x¯ = 15.8
Sample standard deviation; s = 3.85
At 90% Confidence interval, z = 1.645
Formula for confidence interval is;
CI = x¯ ± z(s/√n)
Thus;
CI = 15.8 ± 1.645(3.85/√49)
CI = 15.8 ± 0.90
CI = 14.90 to 16.70 tons
Write the fraction 46/90 in its simplest form

Tell whether the orthocenter is inside, on, or outside the triangle. Then find the coordinates of the orthocenter.
L(0,5), M(3,1), N(8,1): Is it outside, inside or on?
The orthocenter is ( , )
Answer:
see explanation
Step-by-step explanation:
The orthocentre is
• Inside all acute triangles
• Outside all obtuse triangles
• On all right triangles
To determine if the triangle is any of the above, we require the lengths of the 3 sides of the triangle.
Calculate the lengths using the distance formula
d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]
L(0, 5) and M(3, 1)
LM = [tex]\sqrt{(3-0)^2+(1-5)^2}[/tex] = [tex]\sqrt{3^2+(-4)^2}[/tex] = [tex]\sqrt{9+16}[/tex] = [tex]\sqrt{25}[/tex] = 5
L(0, 5) and (N(8, 1)
LN = [tex]\sqrt{(8-0)^2+(1-5)^2}[/tex] = [tex]\sqrt{8^2+(-4)^2}[/tex] = [tex]\sqrt{64+16}[/tex] = [tex]\sqrt{80}[/tex] = 4[tex]\sqrt{5}[/tex]
M(3, 1) and (N(8, 1)
MN = [tex]\sqrt{(8-3)^2+(1-1)^2}[/tex] = [tex]\sqrt{5^2+0^2}[/tex] = [tex]\sqrt{25}[/tex] = 5
Given 3 sides of a triangle a, b, c where c is the longest side, then
• a² + b² = c² ⇒ right triangle
• a² + b² < c² ⇒ acute triangle
• a² + b² > c² ⇒ obtuse triangle
Here a = 5, b = 5, c = 4[tex]\sqrt{5}[/tex]
a² + b² = 5² + 5² = 25 + 25 = 50
c² = (4[tex]\sqrt{5}[/tex] )² = 80
Since a² + b² < c² then triangle is obtuse and the orthocentre is outside the triangle.
The orthocentre is the point of intersection of the 3 Altitudes of the triangle.
We only require to find the equation of 2 of the altitudes and solve them simultaneously to obtain the coordinates of the orthocentre.
An Altitude is a line from a vertex at right angles to the opposite side
Altitude from M to LN
Calculate the slope of LN using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex] = [tex]\frac{1-5}{8-0}[/tex] = [tex]\frac{-4}{8}[/tex] = - [tex]\frac{1}{2}[/tex] ⇒ [tex]m_{perpendicular}[/tex] = 2
Equation of altitude
y - 1 = 2(x - 3)
y - 1 = 2x - 6
y = 2x - 5 → (1)
Altitude from N to LM
m = [tex]\frac{1-5}{3-0}[/tex] = - [tex]\frac{4}{3}[/tex] ⇒ [tex]m_{perpendicular }[/tex] = [tex]\frac{3}{4}[/tex]
Equation of altitude
y - 1 = [tex]\frac{3}{4}[/tex](x - 8)
y - 1 = [tex]\frac{3}{4}[/tex] x - 6
y = [tex]\frac{3}{4}[/tex] x - 5 → (2)
Equating (1) and (2)
2x - 5 = [tex]\frac{3}{4}[/tex] x - 5 ( multiply through by 4 )
8x - 20 = 3x - 20
5x - 20 = - 20 ( add 20 to both sides )
5x = 0 ⇒ x = 0
Substitute x = 0 into (1)
y = 0 - 5 = - 5
The orthocentre is (0, - 5 )
Answer:
The orthocenter is outside the triangle, at (0, -5)
Step-by-step explanation:
The orthocenter is the intersection of the altitudes. So let's find the slope-intercept equation of "LM" "MN" and "LN" then determine it's perpendicular:
LM: slope = m = 1-5/3-0 = -4/3, equation => y = -4/3x + 5, perpendicular => y = 3/4x + b
this line passes through the opposite point, (8, 1)...therefore we can find b:
y = 3/4x + b
1 = 3/4(8) + b, b = -5, equation => y = 3/4x - 5
______________________________________
MN: slope = m = 1-1/8-5 = 0, equation => y = 1, perpendicular => x = ?
the line passes through the opposite point (0, 5)...so we can find ? or b:
x = ?, equation => x = 0
______________________________________
LN: slope = m = 1-5/8-0 = -4/8 = -1/2, equation => y = -1/2x + 5, perpendicular => y = 2x + b
the line passes through the opposite point (3, 1)...so we can find b:
1 = 2(3) + b, b = 1-6 = -5, equation => y = 2x - 5
______________________________________
System of Equations:
[tex]\begin{bmatrix}y=\frac{3}{4}x-5\\ y=2x-5\\ x=0\end{bmatrix}[/tex]
[tex]\mathrm{Substitute\:}y=\frac{3}{4}x-5: \begin{bmatrix}x=0\\ \frac{3}{4}x-5=2x-5\end{bmatrix}[/tex]
[tex]\mathrm{Substitute\:}x=0: \begin{bmatrix}\frac{3}{4}\cdot \:0-5=2\cdot \:0-5\end{bmatrix}[/tex]
[tex]\mathrm{Simplify\:}: \begin{bmatrix}-5=-5\end{bmatrix}[/tex]
[tex]\mathrm{For\:}y=\frac{3}{4}x-5,\\\mathrm{Substitute\:}x=0,\\y=\frac{3}{4}\cdot \:0-5 = -5[/tex]
[tex]y=-5,\:x=0[/tex]
