Andrews [41]3 years ago
8 0

Answer:

41cm

Step-by-step explanation:

The circumference of a circle is 82π

Therefore r can be calculated as follows

2 × π × r= 82× π

2πr= 82π

r = 82π/2π

r= 41

Hence r is 41cm

Bob had 20 apples, if he gave away 14 how many would he have left?
vodka [1.7K]
6, Bob will have 6 apples after he gives 14 away. 

To solve this problem, we must first understand what it is asking. Since Bob is giving away apples, he is subtracting them from his total amount. So, now we do the subtraction.

20 - 14 = 6, so Bob will have 6 apples after he gives 14 away.

yanalaym [24]

Answer:

94cm

Step-by-step explanation:

wingspan         length

60 meters        70.5 m

----------------- = ----------------

80 cm                   x

Cross multiply

(60 m)x = (70.5 m)(80 cm)

Solve for x by dividing both sides of equation by 60 m:

x = (70.5 m)(80 cm) / (60 m) = 94 cm

The length of the model is 94 cm.

-8(7x+8)=-8x+34 i need help solving this equation .
Anarel [89]

Answer:

x = -49/24

Step-by-step explanation:

The first step in solving this equation is to use the distributive property to eliminate the parentheses on the left side of the equation.

-8(7x+8) = -8x + 34

-56x - 64 = -8x + 34

Next, we should add 8x to both sides of the equation.

-48x - 64 = 34

Next, we can add 64 to both sides of the equation.

-48x = 98

Finally, we can divide both sides of the equation by -48 to get the variable x alone on the left side of the equation.

x = -98/48 = -49/24

Therefore, the correct answer is -49/24.

Hope this helps!
