Answer: 29.2%
Step-by-step explanation:
The total surface area is 196.9 million square miles and out of this, land occupies 57.5 million square miles.
The probability that a meteorite would hit land is the percentage of and out of the entire planet area:
= Land area/ Total earth surface area
= 57.5/ 196.9
= 29.2%
Answer:
x=-4 and y=4
Step-by-step explanation:
(6x+9y)-(6x+7y)=12-4=8
--> 9y-7y=8
-->2y=8-->y=4
-->6x+7×4=4 -->x=-4
If we write y=f(x)=(x-h)²+k, then y-k=(x-h)². This is vertex form where the vertex is (h,k)=(3,3) so h and k are both 3. We can see this if we put x=3 in the shifted function. This is a minimum point for the function because for every other x f(x) is greater then 3. The minimum point is the vertex.
Answer:
yes because a is the answer
Step-by-step explanation:
Answer:
7x + 34 = 90
-34 -34
7x = 56
Divide by 7 on both sides:
X = 8 degrees
A right angle equals 90 degrees so that must mean angle 7x + 34 must equal to 90 so we solve for x.
A triangle equals = 180 degrees
A quadrilateral equals = 360 degrees
A right angle equals = 90 degrees
A straight line equals = 180 degrees
