Answer:

The total surface area of the figure is approximately 10.2 m²

Step-by-step explanation:

The dimensions of the solid are;

The shape of the solid = An half cylinder

The diameter of the cylinder, D = 1.6 m

The length of the cylinder, l = 2 m

The surface area of the curved part of the solid = π × D × l ÷ 2

Therefore;

The surface area of the curved part of the solid = π × (1.6 m) × 2 m/2 ≈ 5.03 m²

The area of the curved surface, V = 5.03 m²

The area of the rectangular top, A = 1.6 m × 2 m = 3.2 m²

The area surface of the semi-circular sides of the figure = 2 × π·D²/4 ÷ 2

Therefore;

The area surface of the semi-circular sides of the figure = 2 ×π × (1.6 m)²/4 ÷ 2 ≈ 2.01 m²

The total surface area of the figure, A = 5.03 m² + 3.2 m² + 2.01 m² = 10.24 m²

The total surface area of the figure ≈ 10.2 m² (rounding to 1 decimal place)

Answer: 25%

Step-by-step explanation:

Given

Initial Cost of share [tex]C.P.=16\$[/tex]

After a month, its selling price is [tex]S.P.=20\$\ \text{per share}[/tex]

The gain percentage is given by

[tex]\Rightarrow \text{Gain }\ \%=\dfrac{\text{S.P.-C.P.}}{\text{C.P.}}\times 100[/tex]

[tex]\Rightarrow \text{Gain}\ \%=\dfrac{20-16}{16}\times 100=25\%[/tex]

Answer:

the dimensions of the rectangle are 10 and 7.

Step-by-step explanation:

Given;

area of the rectangle, A = 70 m²

dimensions of the rectangle, = x - 11 and x - 8

The area of rectangle is calculated as;

A = L x B

70 = (x - 11)(x - 8)

70 = x² - 8x - 11x + 88

0 = x² - 8x - 11x + 88 - 70

0 = x² - 19x + 18

0 = x² - x - 18x + 18

0 = x(x - 1) -18(x - 1)

0 = (x - 18)(x - 1)

0 = x - 18     or    

0 = x - 1

x = 18 or 1

The dimensions of the rectangle are calculated as;

L = 18 - 11  = 7

B = 18 - 8 = 10

Therefore, the dimensions of the rectangle are 10 and 7.

Answer: [tex]\frac{1}{27}[/tex]

Step-by-step explanation:

Anything to the third power means it is multiplied by itself 3 times.

   --> [tex](\frac{1}{3})^{3} =(\frac{1}{3})(\frac{1}{3})(\frac{1}{3})=\frac{1}{27}[/tex]

Answer: 4,84,920

Step-by-step explanation:

Given

The rent per month is 1347

for a year it is 12 months

for 30 years it is [tex]30\times 12=360\ \text{months}[/tex]

Rent for 30 years it is

[tex]\Rightarrow \text{rent}=1347\times 360=484,920[/tex]

Answer:

The standard error between the sample mean is approximately 0.3412

Step-by-step explanation:

The equation for the standard error of a difference in sample mean of equal sample sizes is given as follows;

[tex]SE(\overline x_1 - \overline x_2)={\sqrt{\dfrac{s_{1}^{2} }{n_{1}}+\dfrac{s _{2}^{2}}{n_{2}}}}[/tex]

The given parameters are;

The number of sample of southern grass cicadas, n₁ = 20

The mean body length of the southern grass cicadas, [tex]\overline x _1[/tex] = 16.22 mm

The standard deviation, s₁ = 1.34 mm

The number of sample of citrus cicadas, n₂ = 20

The mean body length of the citrus cicadas, [tex]\overline x _2[/tex] = 13.41 mm

The standard deviation, s₂ = 0.73 mm

[tex]SE(16.22 - 13.41)={\sqrt{\dfrac{1.34^{2} }{20}+\dfrac{0.73^{2}}{20}}} \approx 0.3412[/tex]

The standard error between the sample mean, SE ≈ 0.3412

Answer: 4.6

Step-by-step explanation:

Answer:

a. 5,040 ways

b. 210 ways

Step-by-step explanation:

a) We want to pick 4 numbers out of 10 given that orders matter

If orders do matter, it will be a permutation problem

Mathematically;

n P r = n!/(n-r)!

In this case, n is 10 and r is 4

Thus, we have it that;

10 P 4 = 10!/(10-4)! = 5,040

b) if orders do not matter

It will be a combination problem

n C r = n!/(n-r)!r!

n = 10 and r = 4

10 C 4 = 10! /(10-4)!4!

= 210

Answer: 347.01

Step-by-step explanation:

Larger figure lxwxh= 7.5*3.95*7.5=222.1875

Smaller figure lxwxh= 8*3.95*3.95=124.82

Add 222.1875+124.82= 347.0075 rounded= 347.01

Answer:

1) x = 18 2) x = 7

Step-by-step explanation:

Edit: Decided to solve the second too! :)

1)

12/16 = x/(x+6)

12x + 72 = 16x

72 = 4x

x = 18

2)

(-4 + 4x)/64 = 27/72

-288 + 288x = 1,728

288x = 2,016

x = 7

Answer: H(-3 , 6)

X increase is horizontal

Y increase is vertical

Answer:

add 3.99 + 6.99 + 5.99 = 16.97 divide 14.50 by 16.97 you will get .854 multiply by 100 it is %85.4 that is the percentage he paid then he saves 100 - 85.4 = %14.6

Answer:

50.27

Step-by-step explanation:

A= π r^2

The radius is equal to half of the diameter.Which in this case would be 4 since your diameter is 8.

A = π * 4 ^2

A = 50.27

[tex]3.27*10^{5}=327000[/tex]

Since 2 inches = 6 ft and length of room in the place = 7 inches,

(2x3.5) inches = 6x3.5 ft

7 inches = 21ft

Actual Length of Room = 21 ft.

Width of Room in plane = 3 inches

(2x1.5) inches = 6 x 1.5 ft

= 9 ft

Actual Length of Rook = 9 ft.

Actual Area of Room = Actual Length of Room x Actual Width of Room = 21 x 9 = 189 ft^2

Step-by-step explanation:

Answer:

C. 48 lizards and 24 frogs

Step-by-step explanation:

Let F = number of frog lures, and let L = number of lizard lures.

Marion bought 14 packages of plastic frog and lizard fishing lures.

She bought frog lures in packages of 4 and lizard lures in packages of 6 for a total of 72 lures.

F + L = 72

F/4 + L/6 = 14

12 * F/4 + 12 * L/6 = 12 * 14

         3F + 2L = 168

(+)      -3F - 3L = -216

------------------------------

                   -L = -48

L = 48

F + L = 72

F + 48 = 72

F = 24
