Answer:
1/4, or 4 times smaller
Step-by-step explanation:
Since the surface area of a cube is just the combination of the area of all of the square sides, and the formula for those is s^2, if the side length was decreased by 1/2 then the surface area would decrease by (1/2)^2=1/4. Hope this helps!
Answer:
a) -7 & b) -6
Step-by-step explanation:
Here,
a) x = 0
Solution ↦
b) x = -1

8 because 24 divided by 3 is eight
Answer:
Wendy leaves school to go home. She walks 60 yards north and then 80 yards west. She is 10 yards from the school.
Step-by-step explanation:
The trigonometric ratios have been determined and the angles T and U are complementary.
<h3>What are Trigonometric Ratios?</h3>
Trigonometric Ratios are ratios of the side of a right-angled triangle. These are used to find the missing sides and angles of a right-angled triangle.
A right-angled triangle is a triangle with a measure of one of the angles as 90 degrees.
The triangle TUV is a right-angled triangle, the sides of the triangle are t, u, and v.
Part 1:
The angle T is not equal to angle U.
But by the angle sum property,
T + U + V = 180
T + U = 90
Both the angles are complementary.
Part 2:
The trigonometric ratios are as follows:
sin T = t/v
cos T = u/v
sin U = u/v
cos U = t/v
Part 3:
From the data in part 2,
Options C and D are the correct statements.
sin T = cos U
cos T = sin U
Part 4:
sin 37 = cos ( 90-37)
sin 37 = cos 53
