Answer:
The 9th and 11th students are also boys.
Step-by-step explanation:
Every other student is a boy. Since the 7th student is a boy this means the 8th student is a girl.
You can also think of it with odd numbers. Every odd numbered student is a boy.
Answer: C(t) = 0.4t + 4
Step-by-step explanation:
Let t represent the total number of minutes of using a computer at the internet cafe.
The cafe charges an initial fee to use the computer and then an additional price per minute of usage. The initial charge to use the computers is $4 and the total charge would be $6 for 5 minutes of use. This is expressed as
5t + 4 = 6
5t = 6 - 4 = 2
t = 2/5 = 0.4
It means that the charge per minute would be $0.4
Therefore, the equation for the function C(t), representing the total cost of using a computer for t minutes at the internet cafe is
C(t) = 0.4t + 4
Answer:
A
Step-by-step explanation:
surface area is solving for the entire surface. Thus, you find the area of the triangles and the square base.
The single transformation that can be used to map T₁ onto T₂ is Rotate T₁ 180° about the origin.
<h3>What transformation would map T₁ onto T₂?</h3>
When a shape is rotated 180° about the origin, it means that the points go from (x, y) to (-x, -y).
The points on T₁ if rotated 180° about the origin would go from:
(-2, -2) to (2, 2)
(5, -6) to (-5, 6)
(5,0) to (-5, 0)
These are the points of T₂ so the way to map T₁ on T₂ is to use a 180° about the origin.
