Answer:
SA=64
V=28
Step-by-step explanation:
formula for SA: 2(lw+hw+lh)
formula for volume: l*w*h
where
l-(length)=2
w-(width)=2
h-(height)=7
lets solve for SA first:
2(2*2+2*7+2*7)
2(4+14+14)
2(32)
64
SA=64
now lets solve 4 volume
v=lwh
v=2*2*7
v=28
(4/5) / (7/15) =
4/5 * 15/7 =
60/35 reduces to 12/7...so ratio is 12:7 or 1 5/7

Answer: The correct option is (D) P″(9, -12) and Q″(15, -3).
Step-by-step explanation: Given that triangle PQR is dilated by a scale factor of 1.5 to form triangle P′Q′R′. This triangle is then dilated by a scale factor of 2 to form triangle P″Q″R″.
The co-ordinates of vertices P and Q are (3, -4) and (5, -1) respectively.
We are to find the co-ordinates of the vertices P″ and Q″.
Case I : ΔPQR dilated to ΔP'Q'R'
The co-ordinates of P' and Q' are given by
Case II : ΔP'Q'R' dilated to ΔP''Q''R''
The co-ordinates of P'' and Q'' are given by
Thus, the co-ordinates of the vertices P'' and Q'' are (9, -12) and (15, -3).
Option (D) is CORRECT.
Step-by-step explanation:
Based on the given coordinates, the continents that are located at the coordinates are:
- North America
- Asia
- South America
- Africa
<h3>What continents are mentioned?</h3>
The coordinates, 60°N, 100°W are for a location in Canada. Canada is a nation in the continent of North America.
The coordinates 60°N, 100°E is in Russia. Russia is both in Europe and Asia but the part of Russia where these coordinates point to is in the Asian side.
20°S, 60°W is a location in Paraguay which is in South America and 20°N, 20°E is a location in Chad which is in Africa.
Rest of the question:
1. 60°N, 100°W
2. 60°N, 100°E
3. 20°S, 60°W
4. 20°N, 20°E
