Answer:
900π m2
Step-by-step explanation:
surface are of a sphere is 4π(r)^2
now diameter is 30m,so radius will be 15 m
how, 4π(15)^2=900π (m2)
Answer:
x= 4, -1
Step-by-step explanation:
-2x - 2 + x^2 + x + 180 - 2x - 2 = 180
add like terms and put in descending order
x^2 - 3x + 176 = 180
subtract 180 from both sides
x^2 - 3x - 4 = 0
factor out the equation
(x-4)(x+1)=0
solve for x
x-4=0 x+1=0
x=4 x=-1
7 red, 8 yellow, 9 white......total = 24 roses
probability first pick is white : 9/24
probability second pick is yellow : 8/23
probability of both : 9/24 * 8/23 = 72/552 reduces 3/23 <====
1 yard = 36 inches
3 * 36 = 108
1 foot = 12 inches
108 + 12 = 120
So 3 yards and 1 foot is equal to 120 inches.
120 is greater than 100 so 3 yards and 1 foot is greater than 100 inches.
Answer:
A) Reflection.
Step-by-step explanation:
From the figure shown, we can see that the blue triangle is flipped about the x-axis to form the red triangle.
When an object is flipped about a line, then this transformation is called reflection about that line.
Thus, we can say that reflection is taking place in the figure shown in which the x-axis is acting like a mirror. The blue triangle is the pre-image and the red triangle is the image after reflection.
The reflection about x-axis is given by:
We can check the co-ordinates of the triangles and confirm the the transformation occurring
Points of pre-image triangle:

Points of image triangle

Thus, the transformation is reflection.
