Answer:

37.5%

Step-by-step explanation:

100/160= 0.625

1 - 0.625 = 0.375

To get the percentage from a decimal, multiply by 100:

(0.375)100 = 37.5%

To check you work just multiply 0.375 or 37.5% with 160 and then subtract that product from 160 and it should equal 100:

(0.375) 160 = 60

160 - 60 = 100

Answer:

20%

Step-by-step explanation:

The reason it is 20% is due to the fact that if you put it in a form showing 250/250 = 100/100 and put another proportional rate underneath it showing 200/250 = x/100, you would have to multiply the numerator of the fraction on the left by the denominator of the fraction on the right to get 20000. Now you divide 250 from 20000 and get x for 80, resulting in 80/100 or 80%. All you have to do now is subtract 100-80, which equals 20, resulting in 20%.

Hope that helps!! It's my first time in answering so, ya. ;D goodluck!

How far is the little guy from the flagpole (assuming a right angle between the flagpole and the ground)? Explain how you got yo
Naya [18.7K]

Answer:

b = 9 ft

Step-by-step explanation:

Pythagorean Theorem:

a^2 + b ^2 = c^2

Given:

a = 12

b = ?

c = 15

Plug in values:

12^2 + b^2 = 12^2

Solve for b^2:

b^2 = 15^2 - 12^2

b^2 = 225 - 144

b^2 = 81

Take square root of both sides to find b:

sqrt(b^2) = sqrt(81)

b = 9


Hope this helps! :)

Write the rule of the nth term of each sequence 7,4,1,-2
Zarrin [17]

Answer:

a_{n} = 10 - 3n

Step-by-step explanation:

the terms 7, 4, 1, - 2 form an arithmetic sequence with n th term

a_{n} = a_{1} + (n - 1)d

where d is the common difference and a_{1} the first term

here d = - 2 - 1 = 1 - 4 = 4 - 7 = - 3 and a_{1} = 7, hence

a_{n} = 7 - 3(n - 1) = 7 - 3n + 3 = 10 - 3n
