Below are the rates of travel of 4 shipping trucks. Which truck drove the fastest rate? Truck A: 300 miles in 4 hours Truck B: 2
Tasya [4]

Answer:

Truck D.

Step-by-step explanation:

Below are the rates of travel of 4 shipping trucks.

Truck A: 300 miles in 4 hours Truck B: 240 miles in 3 hours Truck C: 325 miles in 5 hours Truck D: 170 miles in 2 hours.

Speed = distance/time

Speed of Truck A,

v_A=\dfrac{300}{4}\\\\v_A=75\ mph

Speed of Truck B,

v_B=\dfrac{240}{3}\\\\v_B=80\ mph

Speed of Truck C,

v_C=\dfrac{325}{5}\\\\v_C=65\ mph

Speed of Truck D,

v_D=\dfrac{170}{2}\\\\v_D=85\ mph

It can be seen that the speed of Truck D is more out of Trucks A,B and C. Hence, Truck D is moving at a faster rate.

(Evaluate each logarithm. Use the change of base formula when necessary) helpppp y’all
Dmitry [639]

The value of \log _{6}(36) is 2.

Solution:

Given expression is \log _{6}(36).

<u>To evaluate the expression:</u>

\log _{6}(36)

36 can be written as 6².

       =\log _{6}\left(6^{2}\right)

Using log rule: \log _{a}\left(x^{b}\right)=b \cdot \log _{a}(x)

       =2 \log _{6}(6)

Using log rule: \log _{a}(a)=1 so that \log _{6}(6)=1

       = 2(1)

       = 2

\log _{6}(36)=2

Hence the value of \log _{6}(36) is 2.

(Use Solving Systems by Graphing to find a solution for this question)
Ray Of Light [21]

Answer:

5 months

Step-by-step explanation:

One cellphone provider charges AED10 per month plus an activation fee of AED20.

If I used the services of this cellphone provider for x months, total charges for the services,

y = 10x + 20 --------(1)

Similarly, charges for the second cellphone provider for x months of uses will be,

y = 11x + 15 -------(2)

Input-output table for equation (1)

x      1           2            3            4            5

y     30        40         50          60          70

Input output table for equation (2)

x      1           2            3            4            5

y     26        37          48          59         70

From these tables, we find (5, 70) is a common point for both.

It reveals that after the uses of 5 months charges for both the cellphone providers will be same (y = $70)
