Answer:

∠ p ≈ 59°

Step-by-step explanation:

Using Pythagoras' identity in right triangle ABD to find DB

DB² = 5² + 6² = 25 + 36 = 61 ( take square root of both sides )

DB = \sqrt{61}

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

Using the cosine ratio in right triangle DBC

cos p = \frac{adjacent}{hypotenuse} = \frac{DC}{DB} = \frac{4}{\sqrt{61} } , thus

p = cos^{-1} ( \frac{4}{\sqrt{61} } ) ≈ 59°

Maria-Jose is a math tutor. She charges a one-time introduction fee of $25.00 and the cost of the tutoring sessions is shown bel
Feliz [49]

Answer:

y=6x+25

Step-by-step explanation:

y will be the whole cost. 6 is how many sessions you have and x is the cost of each of those sessions. The one time introduction fee is 25. you would add 25 plus 6 times the cost of sessions (x) and you would get your answer (y).

Help me plz. The sides of a rectangular terrain are given by the expressions (x - 5) y
tatyana61 [14]

Area = (x - 5)(x – 7)

Area = x(x - 7) - 5(x - 7)

Area = x^2 -7x -5x + 35

Area = x^2 -12x + 35

algebraic expression that represents its area: x^2 -12x + 35

x^2 - 12x + 35 = 195

x^2 - 12x + 35 - 195 = 0

x^2 - 12x - 160 = 0

x^2 - 8x - 20x - 160 = 0

x (x + 8) - 20 (x + 8) = 0

(x + 8) (x - 20) = 0

(x + 8) = 0

(x - 20) = 0

x = - 8 (not a solution)

x = 20

hence,

length = x - 5

length = 20 - 5

length = 15 m

width = x - 7

width = 20 - 7

width = 13 m

perimeter = 2(13) + 2(15)

perimeter = 26 + 30

perimeter = 56 m²

What am I doing wrong here?
Yanka [14]

Answer:

$879.19

Step-by-step explanation:

I'm not sure how you got that, but here's what I did.

To calculate tax:

Cost before tax * Tax% = Tax

$815.95 * 7.75% = $63.24

To calculate cost after tax:

Tax + Cost before tax = Cost after tax

$63.24 + $815.95 = $879.19
