Answer:
132 m².
Step-by-step explanation:
What's the surface area of each lateral face of this pyramid?
Each lateral face of this pyramid is a triangle, with
- a height of 8 meters
- on a base 6 meters.
The base of this pyramid is a square. As a result, all four lateral sides are congruent. The area of each of these triangle is thus
.
The base of this pyramid is a square. The length of a side of this square is 6 meters. The area of the base will be
.
Put the five faces together to get the total surface area of this square pyramid:
.
Answer: on the first day, they hiked 9 miles.
On the second day, they hiked 16 miles.
Step-by-step explanation:
Let x represent the distance that the two hikers hiked from the first mountain to the second mountain.
Let y represent the distance that the two hikers hiked from the second mountain to the hollow.
The total distance is 25mi. This means that
x + y = 25 - - - - - - - - - - - - - -1
If the distance between the second mountain and the hollow is 7mi more than the distance from the first mountain to the second mountain, it means that
y = x + 7
Substituting y = x + 7 into equation 1, it becomes
x + x + 7 = 25
2x = 25 - 7
2x = 18
x = 18/2 = 9
y = x + 7 = 9 + 7
y = 16
Answer:
D
B
Step-by-step explanation:
1. x² - 5x = 14
x² -5x -14 = 0
x² +2x -7x -14 = 0
x(x + 2) -7(x + 2) = 0
x - 7 or x + 2 = 0
x = 7 or x = -2
2. y² + 6y + 9 = 49
y² + 6y +9 -49 = 0
y² +6y -40 = 0
y² +10y -4y -40 = 0
y(y + 10) -4(y + 10) = 0
y -4 or y + 10 = 0
y = 4 or y = -10
Answer:
Idk if its multiple choice but you can do 1 of 2 ways theres using distance formula =√(5-3)sq+(1-4)sq
=√4+9
=√13 <--
or
3.6 units
Given: The two points that are P(5,1) and Q(3,4).
To find: The distance between these two points.
Solution: It is given that there are two points that are P(5,1) and Q(3,4).
The distance between these two points can be found out as using the distance formula that is: 3.6
Thus, the distance between the given two points is 3.6 units.
So you choose 13 or 3.6 Hope this helps :)
