Triangle P Q R is shown. Angle P Q R is a right angle. The length of hypotenuse P R is q, the length of P Q is r, and the length

of Q R is p.,
Which cosine ratios are correct for ΔPQR? Check all that apply.

cos (P) = StartFraction r Over q EndFraction
cos (P) = StartFraction p Over q EndFraction
cos (Q) = StartFraction r Over p EndFraction
cos (R) = StartFraction r Over p EndFraction
cos (R) = StartFraction p Over q EndFraction

Answer:

<em>1</em><em>.</em><em> </em>cos (P) = StartFraction r Over q EndFraction

<em>2</em><em>.</em>cos (R) = StartFraction p Over q EndFraction

Step-by-step explanation:

1.

\cos(p)  =  \frac{r}{q}

2.

\cos(r)  =  \frac{p}{q}

You are hiring a limousine. One company charges a $60 reservation fee plus another $15 per hour. A second company charges a $25
anzhelika [568]

Answer:

7 hours

Step-by-step explanation:

Step one:

given data

let the total charges be y and the number of hours be x

Company A charges

$60 reservation fee plus another $15 per hour.

so

y=60+15x----------1

Company B charges

$25 reservation fee plus another $20 per hour

y=25+20x------------2

Step two:

equate the 2 expressions above we have

60+15x=25+20x

collect like terms

60-25=20x-15x

35=5x

divide both sides by 5

x= 35/5

x= 7 hours

A woman walks 5 rounds along the border of a square field of area 49². Find the total distance she walks in m.​
Luba_88 [7]
You need to estimate the square root of 200 ft². Rewrite 200 as 2 x 100, then square root of (2*100) is:

10*sqrt(2). The sqrt(2) = 1.414, so the length of each side of the square will be 10*1.414 = 14.14 ft or about 14 ft.

7x-4=3x+ 8

-3x of both sides 4x-4=8
plus 4 to both sides 4x=12

12 divide by 4 = 3
