The formula for the money multiplier is :
1/ Reserve rate
so, the answer would be :
1/0.05

The sides OP and RO of triangle POR are produced to points S and T respectively. If ∠SPR = 145° and ∠POT = 115° , find ∠PRO

Margarita [4]

Answer:

$\angle PRQ = 80$

Step-by-step explanation:

Given

$\angle SPR = 145^o$

$\angle POT = 115^o$

See attachment

Required

Find $\angle PRO$

First, calculate $\angle RPO$

$\angle RPO + \angle SPR = 180$ --- angle on a straight line

So, we have:

$\angle RPO + 145 = 180$

Collect like terms

$\angle RPO = 180 - 145$

$\angle RPO = 35$

Next, calculate PQR

$\angle POR + \angle POT = 180$

So, we have:

$\angle POR + 115 = 180$

Collect like terms

$\angle POR = 180-115$

$\angle POR = 65$

So, PRO is calculated as:

$\angle PRO + \angle POR + \angle RPO = 180$ --- angles in a triangle

So, we have:

$\angle PRO + 65 + 35= 180$

$\angle PRO + 100= 180$

Collect like terms

$\angle PRO = 180-100$

$\angle PRO = 80$

Answer:

${x}^{2} + 4x - 9 = 5x + 3 \\ {x }^{2} - x - 12 \\ {x}^{2} - 4x + 3x - 12 \\ x(x - 4) + 3(x - 4) \\ (x - 4)(x + 3) \\ x = 4 \: and - 3$

In a sample of 800 U.S. adults, 219 think that most celebrities are good role models. Two U.S. adults are selected from this sa

shutvik [7]

Answer:

Step-by-step explanation:

P=(219/800)×(218/799)≈0.0747≈0.075

800-219=581

P=(581/800)×(580/799)≈0.527

P( 1 think role models and one thinks not role models)+P(both thinks they are role models)=(219/800)×(581/799)+(219/800)×(218/799)=(219×581+219×218)/(800×799)

=[219(581+218)]/(800×799)

=(219×799)/(800×799)

=219/800

=0.27375

=0.274
