Answer:
Circumference is equal to pi by diameter
22/7 ×4
the answer is equal to C= π×4
Answer:
x = 98°
Step-by-step explanation:
We know that in a heptagon, there are 900°. <em>So</em>,
900 - (146 + 122 + 142 + 140 + 110 + 142)
We plug that into the calc and we should get 98 as our final answer!
AB = 14
m∠F = 39°
Well the explanation here is simple.
Since the given states that the two triangles, ΔABC and ΔDEF, are congruent, they must have congruent/corresponding parts.
So AB is the same as DE which measures 14, so therefore AB must measure 14.
The same explanation goes to m∠F, ∠C is congruent to ∠F so it must measure 39° too.
Answer: 3 × 
Step-by-step explanation: To write a number in scientific notation, first write a decimal point in the number so that there is only 1 digit to the left of the decimal point. In this case, we can write 30,000 as 3.0000 and notice that there is only 1 digit to the left of the decimal point.
Next, we count the number of places the decimal point would need to move to get back to the original number which is 30,000. Since we would need to move the decimal point 4 places to the right, this gives us an exponent of positive 4. So, we can write this in scientific notation.
3.0000 ×
The exponent is positive because we would need to move the decimal point 4 places to the right in order to get back to our original number.
We can also write it as 3 × since we can drop zeroes at the end of the decimal.
Therefore, 30,000 can be written in scientific notation as 3 × .
Answer:
(-4, 14.4)
Step-by-step explanation:
The midpoint formula is expressed as;
M(X, Y) = {(ax1+bx2/a+b), ay1+by2/a+b}
Get X;
X = ax1+bx2/a+b
X = -13(2)+ 2(3)/2+3
X = -26+6/5
X = -20/5
X = -4
Get Y:
Y =ay1+by2/a+b
Y = 2(6)+3(20)/2+3
Y = 12+60/5
Y = 72/5
Y = 14.4
Hence the coordinate of point P dividing A and B in the ratio 2 to 3 is
(-4, 14.4)
