a ferry shuttles people from one side of a river to the other. the speed of the ferry is still water is 25 mi/h. the river flows
Anarel [89]

Answer:

The Terry's resultant speed is 27mi/h

Direction of ferry=20°

Step-by-step explanation:

(-25,0) + ( 0, 9)= (-25, -9) is the vector representing the movement of the ferry

Speed of ferry = sqrt[(-25)^2 + (-9)^2]

Speed= sqrt (-625 + (-81))

Speed= sqrt(-706)

Speed=26.57mi/h

Nearest tenth,speed= 27mi/h

Tanz° = (-9/-25)

Tanz°= 0.36

Z°= tan^-1 0.36

Z= 19.80°

Nearest tenth,z=20°

What is the surface area
anygoal [31]
Bear in mind that the area of a "parallelogram" is base * height.

notice the picture, the front and back parallelograms, have an altitude/height of 3 cm, and  a base of 8 cm, so the area of one of those two is 3*8.

as far as the left and right parallelograms, they have a base of 7 cm, but the altitude is also 3 cm, so the area of one of those is 3 *7.

bear in mind the altitude/height is the distance from the base to the top, and in this case is just 3 cm.

anyway, you have 4 parallelograms, get the area of each, add them up, and that's the surface area of the figure.

2(3*8) + 2(3*7).

Susan is buying three different colors of tiles for her kitchen floor. She is buying 25 more red tiles than beige tiles, and thr
Vanyuwa [196]
Let us assume that the number of beige tiles bought by Susan = B
Number of red tiles bought by Susan = R
Number of navy-blue tiles bought by Susan =N
Number of tiles bought altogether = 435
Now from the given question we know:
Number of red tiles bought is 25 more than the number of beige tiles.
So
 R = 25 + B
Number of navy blue tiles bought is 3 times that of the number of beige tile bought
So
N = 3B
We already know that the total number of tiles bought is 435
Hence
B + R + N = 435
B + (25 + B) + 3B = 435
5B + 25 = 435
5B = 435 -25
5B = 410
B = 82
R = 25 + B
   = 25 + 82
   = 107
N = 3B
   = 3 * 82
   = 246
So the number of Beige tiles  bought by Susan = 82
The number of red tiles bought by Susan = 107
The number of navy-blue tiles bought by Susan = 246
