Answer:

87.96 meters to the nearest cm.

Step-by-step explanation:

First find the circumference of the wheel

= 2 π r

= 2 π * 28

= 175.929 cm.

So one revolution is equivalent to travelling 175.929 cm.

50 revolutions = 175.929 * 50

= 8796.46 cm.

= 8796.46 / 100

= 87.96 m (answer).

Q= 4(a+b) solve for d

alukav5142 [94]

Answer:

$b= \frac{q - 4a}{4}$

Step-by-step explanation:

ill suppose that you mean : "solve for b" not for d, since there is no d term in the formula given. So:

$q = 4(a + b) \\ q = 4a + 4b \\ 4a + 4b = q \\ 4a + 4b - 4a = q - 4a \\ 4b = q - 4a \\ b = \frac{q - 4a}{4}$

How do I identify the congruent triangles in each figure

Virty [35]

Congruent triangles have the exact same three sides and the exact same angles. They are identical. So if you look at your triangles carefully, they are congruent. :)
