Use prime factorization to find the LCM of 6, 25, and 30

I went to a restaurant and gave the waitress a $15 tip. If the tip was 20% of the dinner how much was the dinner?

prohojiy [21]

Answer:

Dinner only: $75

Dinner and Tip: $90

Step-by-step explanation:

If the tip was $15, and the tip was 20% of the price of dinner, then dinner was $75.

You can find this out by doing 15/20%, which should give you 75.

If the question requires you to add up the price of dinner and the tip, then the total price would be $90

A student wants to check six websites. Four of the websites are social and two are school-related. After checking just two sites

mash [69]

The approximate probability that she checked a social website first, then a school-related website is 0.267.

First step is to calculate the Total number of websites

Total number of websites=Number of school websites+Number of social websites

Total number of websites=2+4

Total number of websites=6

Second step

Probability of checking the social website first

Probability of checking social website=Number of social websites/Total number of websites

Probability of checking social website= 4/6

Third step

Since one social website is checked which means that she is left with 3 social website and 2 school websites

Total number websites=2+3

Total number websites=5

Forth step

Probability of checking social website=Number of school websites/Total number websites

Probability of checking social website=2/5

Fifth step

Probability= 4/6 x 2/5 = 0.2666

Probability=0.267(Approximately)

Inconclusion the approximate probability that she checked a social website first, then a school-related website is 0.267.

Identify the postulate that proves the triangles are congruent.

Ratling [72]

Answer:

ASA

Step-by-step explanation:

Triangle ABD is congruent to triangle BDC by ASA because angle B in ABD is 30 degrees. Then they give you BD which equals BD by the reflexive property. And finally angle D in ABD is also 30 degrees. In triangle BCD, angle B is 30 degrees, BD = BD, and angle D in BCD is 30 degress. So we have an angle (B), side (BD), and another angle (D)

Y=-3x+5 <br> 5x-4y=-3<br> Trying to solve this problem

rodikova [14]

Your answer would be y= 5x/-4 - 3/-4 because you’ll move 5x to the other side of the equal sign then divide -4 to get y by itself
