PLEASE HELPPP!! Triangle HJK and triangle PMK are similar right triangles.

# of guests   waitstaff gratuity
10                      18
20                      36
30                      54
40                      72
50                      90

<span>If the gratuity changes directly with the number of guests, which formula outlines the connection between the gratuity, t, and the number of guests, g? 
t = 1.8g t = g/18 g = 1.8t g = t/18
</span>
18/10 = 1.8
36/20 = 1.8
54/30 = 1.8

direct variation: <span>t = 1.8g</span>

Answer: Step-by-step explanation: Provided Required Identify the depth of the aquarium. Volume is computed as follows: Substitute values for Volume, Length, and Width. Solve for Depth. Therefore, the depth is 14cm.

Your response is C!

Answer:

4:5

Step-by-step explanation:

Start with the equation:

2(3/4m)=D+1/4m

Then, simplify to solve:

5/4m=D

Answer:

Upper limit: 3.116

Lower limit: 3.125

Step-by-step breakdown:

The random circle drawn by Hellen has a circumference of C=405 mm, measured to 3 significant figures, leading to a diameter, d, of 130 mm, accurate to 2 significant figures.

We utilize the formula

Substituting in the figures provides:

Consequently, Hellen’s value for π is recorded as 3.115 to three decimal places.

To find both limits, we divide the specified level of precision by two.

This figure is then added to the rounded number to determine the upper limit:

3.115+0.0005=3.1155

The lower limit calculates as 3.115-0.0005=3.1145
