Answer:

x = 13.75 units

Step-by-step explanation:

Right triangle

tan 58 = opposite side / adjacent side

tan 58 = 22/x

x = 22/ (tan 58) = 13.75

A new Youth Activity Center is being built in Hadleyville. The perimeter of the rectangular playing field is 430 yards. The leng

scoundrel [369]

Answer:

Width = 44 yards

Length = 171 yards

Step-by-step explanation:

Given:

<em>Perimeter of the rectangular field = 430 yards.</em>

Let:

<em>The length of the field be L</em>

<em>The width of the field be W.</em>

From the question:

<em>The length of the field is 5yards less than quadruple the width. This implies that;</em>

L = 4W - 5

But.

Perimeter (P) of a rectangle is given by:

P = 2(L + W) ---------------(i)

Substitute the values of P = 430, L = 4W - 5 and W into equation (i) as follows;

430 = 2(4W - 5 + W)

430 = 2(5W - 5)

430 = 10W - 10

10W = 430 + 10

10W = 440

Divide both sides by 10

W = 44

Therefore, the width of the field is 44 yards.

Remember that,

L = 4W - 5

[Now substitute W = 44]

L = 4(44) - 5

L = 176 - 5

L = 171

Therefore, the length of the field is 171 yards

74% of freshmen entering public high schools in 2006 graduated with their class in 2010. A random sample of 81 freshmen is selec

Assoli18 [71]

Answer: Probability that the proportion of students who graduated is greater than 0.743 is P = 0.4755

Step-by-step explanation:

Given that,

Probability of freshmen entering public high schools in 2006 graduated with their class in 2010, p = 0.74

Random sample of freshman, n = 81

Utilizing central limit theorem,

$P(\hat{p}$

So,

$(P(\hat{p}>0.743) = P(Z>0.743 - \frac{0.74}{\sqrt{\frac{0.74(1-0.74)}{81} } } )$

= P( Z > 0.0616)

= 0.4755 ⇒ probability that the proportion of students who graduated is greater than 0.743.

SOMEONE, PLEASE HELP ME OUT!!!!!! WILL MARK BRAINLIEST

Hitman42 [59]

Answer:

see below

Step-by-step explanation:

19. (4x + 8x² - 8) + (x² + 7 - 4x)

= 4x + 8x² - 8 + x² + 7 - 4x

= 8x² + x² + 4x - 4x -8 + 7

20. (7x² - 11 + 16x) + (5x - 3x² - 7)

= 7x² - 11 + 16x + 5x - 3x² - 7

22. (4x² - 12x - 10) - (2x² + x - 3)

= 4x² - 12x - 10 - 2x² - x + 3

23. (7x³ - 9x² - 14x) - (4x³ - 4 - x)

= 7x³ - 9x² - 14x - 4x³ + 4 + x

= 7x³ - 4x³ - 9x² - 14x + x + 4

25. (9x² + 24x - 8) - (5x² + 3x + 10)

= 9x² + 24x - 8 - 5x² - 3x - 10

26. (5x - 12x² + 9x³) - (5x³ + 6x - 3)

= 5x - 12x² + 9x³ - 5x³ - 6x + 3

28. (2x² - 1 + 3x³) + (5 - 13x - 11x²)

= 2x² - 1 + 3x³ + 5 - 13x - 11x²

30. (10x - x² + 8) + (5x² + 1 - 22x)

= 10x - x² + 8 + 5x² + 1 - 22x
