Mult 2 by x you'll get 2x then 2 by 3 you'll get 6 and add 6 to 5, after that you'll get 11 it should look like this 2x+11.

Log (4x-1)+5=8<br><br> Please help me!

nordsb [41]

log (4x-1) + 5 = 8

log (4x-1) = 8 - 5

log (4x-1) = 3

4x - 1 = 10³

4x - 1 = 1000

4x = 1001

x = 1001/4

ok done. Thank to me :>

A motion sensor has a range of 65 meters as shown. The ultrasonic waves sweeping out from the sensor span an angle of 135°.

VMariaS [17]

The approximate area that is within range of the motion sensor is 4975 square meters

<h3>How to determine the area of the range?</h3>

The figure is not given, however the area of the range can be calculated without the figure.

The given parameters are:

Angle, ⊕ = 135°

Radius, r = 65 meters

The area of the range is calculated using the following sector area

$A = \frac{\theta}{360} * \pi r^2$

This gives

$A = \frac{135}{360} * 3.14 * 65^2$

Evaluate

A = 4974.9375

Approximate

A = 4975

Hence, the approximate area that is within range of the motion sensor is 4975 square meters

Customers at an ice cream shop took a survey. The results showed that 144 customers rated the shop as being "very satisfactory."

stepladder [879]

Answer:

320 customers is the answer

Step-by-step explanation:

1. You have to divide 144 by 45% to find one percent of the customers (you get 3.2).

2. Once you get one percent of all of the customers (3.2) you multiply it by 100 to get 100 percent of the customers (or total number of customers).

So, 320 total customers

Have a great day, I hope you like the explination.
