1 answer:

4 0

Use the Pythagorean theorem:

C = √[a^2 + b^2] 
C = √[(20^2 + 15^2] 
C =√[400 + 225] 
C = √(625) 
C = 25 inches 

Answer: 3.25 inches ✔️

. A pair of shoes are $98.75,

djyliett [7]

Answer:

a. saletax = 98.75

100

5 = 98.75

100 1

we cross multiple

5(1) = 100(98.75)

5 = 100(98.75)

divide both side by 5

5 = 100(98.75)

5 5

since 100 can divide 5 so we divide them

= 20(98.75)

amount sale tax = 1975

b. 98.75 × 5 =493.75$

Find the exact angular velocity in radians per hour wind W= 4.1 rpm

nataly862011 [7]

Answer:

1545.66 rad/h

Step-by-step explanation:

We need to find the angular velocity in rad/hour when wind is moving with a speed of 4.1 rpm.

We know that,

1 revolution = 2π rad

1 hour = 60 minute

So,

$4.1\ rmm = 4.1\times \dfrac{2\pi }{(\dfrac{1}{60})}\ rad/h\\\\=1545.66\ rad/h$

So, the required angular velocity is 1545.66 rad/h.
