Mathematics
1 answer:
Butoxors [25]3 years ago
3 0

Answer:

Perimeter = 54.6 cm

Area = 173 cm²

Step-by-step explanation:

sin 30 = x/20

x = 10

cos 30 = y /20

y = 17.3

perimeter = 10 + 17.3 + 10 + 17.3 = 54.6 cm

area = 10 * 17.3 = 173 cm²

Solve for w p=1.2w/h^2
andreyandreev [35.5K]
Solve for w:
p = (1.2 w)/h^2
(1.2 w)/h^2 = (6 w)/(5 h^2):
p = (6 w)/(5 h^2)
p = (6 w)/(5 h^2) is equivalent to (6 w)/(5 h^2) = p:
(6 w)/(5 h^2) = p
Multiply both sides by (5 h^2)/6:
Answer:  w = (5 h^2 p)/6

Which number is a solution of the inequality 8 - 1/4 b &gt; 27
Brrunno [24]

The inequality is 8-1/4x>27. The solution of the inequality is b<-76.

Given that,

The inequality is 8-1/4x>27

We must determine how to address the inequity.

Take,

8-1/4x>27

Multiply the inequality's two sides by its lowest common denominator,

4×8-4×1/4b>27×4

Reduce the expression to the lowers term,

4×8-b>4×27

Calculate the product or quotient,

32-b>4×27

Calculate the product or quotient,

32-b>108

Rearrange unknown terms to the left side of the equation,

-b>108-32

Calculate the sum or difference,

-b>76

Divide the inequality's two sides by the variable's coefficient,

b<-76

Therefore, the solution of the inequality is b<-76.

Rom4ik [11]
Turn both fractions into mixed fractions resulting in 75/2 and 5/2. Then turn them into decimals. 75/2= 37.5 and 5/2= 2.5. Then divide each other  37.5 / 2.5= 15. 15 is your answer. Hope it helped :)
