Answers
Answer:
Option (c) is correct.
Step-by-step explanation:
The four pieces of wood are 36 in., 36 in., 37 in. and z in.
The mean length of the pieces of woods are 36 in
We need to find the length of the fourth piece of wood.
Mean = sum of data/total no of data
[tex]36=\dfrac{36+36+37+z}{4}\\\\144=109+z\\\\z=144-109\\\\z=35\ in.[/tex]
So, the length of fourth piece is 35 inches. Hence, the correct option is (c).

Step-by-step explanation:
the smallest is x
the second is x+2
the 3rd is x+4
next is x+6
the last is x+8
x + (x+2) + (x+4) = (x+6) + (x+8) +3
3x + 6 = 2x + 17
3x - 2x = 17 - 6
x = 11

First, Area of Small rectangle
= l w
= 4 x 2
= 8 square meter
Now, area of Big rectangle
= l w
= 5 x 10
= 50 square meter
Thus, the Area of Figure = 8 + 50 = 58 square meter

Find the principal that will yield an interest of Rs 367.75 in 4½ years at 3½% per annum.
Answers
Answer:
The principle amount = P = $ 2334.92
Step-by-step explanation:
Given
Interest amount I = Rs 367.75
Time period t = 4½ = 9/2 = 4.5 years
Interest rate r = 3½ % = 7/2% = 3.5% = 0.035
To determine
Principal P = ?
Using the simple interest formula
I = Prt
where
I = Interest amount
r = Interest rate
t = time in years
substituting I = Rs 367.75, t = 4.5 years, r = 0.035 in the equation
I = Prt
P = I / rt
= [367.75] / [(0.035)(4.5)]
P = $ 2334.92
Therefore, the principle amount = P = $ 2334.92

Step-by-step explanation:
The formula for the area of a cuboid can be written as ...
A = 2(LW +H(L +W))
When the area of the missing top is subtracted, this becomes ...
A = LW +2H(L +W)
Then the area of 10 boxes will be ...
A = 10×(20×16 +2×14(20+16)) = 10(320 +28(36)) = 13,280 cm²

The ratio of the measures of the three angles in a triangle is 14:5:11. Find the value of x
Answers
Answer:
The three angles are 84º, 30º, and 66º. You multiply the ratio 14:5:11 by 6º.
Step-by-step explanation:
The sum of a triangle's interior angles is 180º. From the information we know:
14xº+5xº+11xº=180ºCombine like terms, 30xº=180ºDivide, xº=6ºNow we can say that the three angles are 14(6)=84º, 5(6)=30º, 11(6)=66º.

Answer: [tex]r=\dfrac{4}{\theta}\text{ cm}[/tex] .
Step-by-step explanation:
We know that , [tex]l= r\theta[/tex] , where l = length of arc , r= radius , [tex]\theta=[/tex] central angle ( in radians).
Here , l= 4 cm
Substitute this value in the formula , we get
[tex]4=r\theta \\\\\Rightarrow\ r=\dfrac{4}{\theta}[/tex]
Hence, the formula of r in terms of [tex]\theta[/tex] is [tex]r=\dfrac{4}{\theta}\text{ cm}[/tex] , where [tex]\theta=[/tex] central angle ( in radians).
