givi [52]

Given :

Brianna is a waitress in an upscale restaurant. On Friday she waited on 12 groups of customers who spent an average of $186 per group.

Her tips averaged 18% of the total amount spent by all the groups of customers that day.

To Find :

Brianna's tip income earnings on Friday.

Solution :

Total amount of money spent by 12 groups :

P = $ 12×186 = $2232 .

She got tip of 18% of the total amount spent by all the groups of customers.

T = P\times \dfrac{20}{100}\\\\T= 2232\times \dfrac{20}{100}\\\\T=\$446.4

Brianna's tip income earnings on Friday is $446.4 .

Hence, this is the required solution.

Given that ABCD is a rhombus, what is the value of x?
SashulF [63]

Answer:

B

Step-by-step explanation:

A rhombus is divided into four congruent triangles. The two given angles are complementary, meaning they add up to 90 degrees. Set up an equation:

(4x-25)+x=90

4x-25+x=90   Take out the parentheses

5x-25=90   Combine like terms

5x=115   Add 25 to both sides so as to isolate the variable

x=23   Divide both sides by 5
