Answer: 6*(13+7) = 60
Step-by-step explanation:
6*13+6*7
6*(13+7) = 6*10 =60
Answer:
38π cm
Step-by-step explanation:
The area of a circle of radius r is A = 2πr.
If the radius is 19 cm, then the area is A = 2π(19 cm), or 38π cm.
Answer:
a) 
b) 
Dividing both sides by 0.448 we got:

We can appy the exponent
in both sides of the equation and we got:

Step-by-step explanation:
For this case we know the following function:

The notation is: x is the weight of the crab in grams, and the output f(x) is the weight of the claws in grams.
Part a
For this case we just need to replace x = 2 gram in the function and we got:

Part b
For this case we know tha value for
and we want to find the value of x who satisfy this condition:

Dividing both sides by 0.448 we got:

We can appy the exponent
in both sides of the equation and we got:

I’m not too sure if I did it correct, but the answer I got was -6x^2+36. I just assumed you’d solve it as usual and then multiply (-3) after distributing-2 to x^2-6. Hope this helps.
Answer:
27 degrees
Step-by-step explanation:
We are given that Angle AEF is 63. We can also see that EAF is a right angle. Since angles in a triangle add up to 180, we can use this to solve for AFE:
Angle AEF + EAF + AFE = 180
63 + 90 + AFE = 180
153 + AFE = 180
AFE = 27
<em>Or we can solve it another way</em>
Since EAF is a right angle, the other angles are complementary (they add up to 90) so...
Angle AEF + AFE = 90
63 + AFE = 90
AFE = 27
