"Find The Total Area Of The Shape"How Should I Solve This? The Answer Is 31.9 Cm

Answers

Answer 1

Answer:

31.9 cm² (3 s.f.)

Step-by-step explanation:

[tex]\boxed{area \: of \: sector = \frac{θ}{360º} \times \pi {r}^{2} }[/tex]

∠AOD

= 360° -60° - 120° -45° (∠s at a pt.)

= 135°

Area of shape

[tex] = \frac{60°}{360°} (\pi)({2}^{2}) + \frac{120°}{360°} (\pi)(3^{2} )+ \frac{45°}{360°}(\pi)( 5 {}^{2}) + \frac{135°}{360°} (\pi)(3 {}^{2} )[/tex]

[tex] = \frac{1}{6} (4\pi) + \frac{1}{3} (9\pi) + \frac{1}{8} (25\pi) + \frac{3}{8} (9\pi)[/tex]

[tex] = \frac{4}{6} \pi + \frac{9}{3} \pi + \frac{25}{8} \pi + \frac{27}{8} \pi[/tex]

[tex] = \frac{61}{6} \pi[/tex]

= 31.9 cm² (3 s.f.)

The fifth part of a number when increased by 5 equals its fourth part decreased by 5. Find the number.​

Answers

Question :-

The fifth part of a number when increased by 5 equals its fourth part decreased by 5. Find the number.

Required Solution :-

The number will be 200.

Explanation :-

Let the number be " x "

[tex]\qquad[/tex] ☀️It's given, the fifth part of a number when increased by 5 equals its fourth part decreased by 5.

[tex]\qquad[/tex] According to the question :-

[tex]\qquad \pmb{\sf\longrightarrow \dfrac{x}{5} + 5 = \dfrac{x}{4} - 5}[/tex]

[tex]\qquad \pmb{\sf\longrightarrow \dfrac{x}{5 }- \dfrac{x}{4} = -5 -5}[/tex]

[tex]\qquad \pmb{\sf\longrightarrow \dfrac{(4x - 5x)}{20} = -10}[/tex]

[tex]\qquad \pmb{\sf\longrightarrow \dfrac{-x}{20} = -10}[/tex]

[tex]\qquad \pmb{\sf\longrightarrow -x = -10 \times 20}[/tex]

[tex]\qquad \pmb{\sf\longrightarrow -x = -200}[/tex]

[tex]\qquad \longrightarrow {\pink{\underline{\underline{\pmb{\sf{ x= 200}}}}}}[/tex]

Therefore

The number will be 200.

A farmer wants to fence in a rectangular area that is mile wide by mile long, as shown in the picture.

Which of the following proportions can the farmer use to calculate how many feet of fencing he will need?

No links pls 100 pts

Answers

Answer:

its number four the last one

Step-by-step explanation:

Answer:

[tex]\frac{\frac{3}{4} mi}{x}[/tex]=[tex]\frac{1 mi}{5,280 ft}[/tex]

Step-by-step explanation:

First find the perimeter of the rectangle to see the total length

2([tex]\frac{1}{8}[/tex])+2([tex]\frac{1}{4}[/tex])

[tex]\frac{3}{4}[/tex]

Then, because you are converting from miles to ft, you can use the ratio of miles/feet to determinte the correct ratio for the perimeter.

The correct ratio is [tex]\frac{1 mi}{5,280 ft}[/tex]

To set these ratios equal to eachother, first see that one side of the equation has miles as the unit, the other side has miles/feet, so you must divide the perimeter by feet to set the ratios equal to eachother.

Therefore, the correct equation is [tex]\frac{\frac{3}{4} mi}{x}[/tex]=[tex]\frac{1 mi}{5,280 ft}[/tex]

Assume that adults have iq scores that are normally distributed with a mean of u = 105 and a standard deviation =20 find the probability that a randomly selected adult has an iq less than 129

Answers

Answer:

P(X<129) ≈ 0.8849

Step-by-step explanation:

I've attached a graph of the normal distribution to help you visualize the problem. To calculate this on a TI-84, we can use the normalcdf function to find the area between the end of the left-tail of the normal distribution to x=129, hence, we are finding P(X<129). We can write this as normalcdf(-1e99,129,105,20) ≈ 0.8849, therefore, the probability that a randomly selected adult has an IQ less than 129 is about 0.8849 or about 88.49% likely to occur.

Which equation represents a constant of proportionality of 25? *

12 points

F. x + 25 = y

G. 25x = y

H. x − 25 = y

J. 5x = y

Answers

Answer:

G

Step-by-step explanation:

An equation of proportionality has the form

y = kx ← k is the constant of proportionality

y = 25x ← has this form with k = 25

y = 5x ← has this form with k = 5

The required equation is y = 25x with k = 25 → G
