Geneva treated her parents to dinner at their favorite restaurant the bill was $74.25 Geneva wants to leave 16% of the total tip
Tanya [424]

Answer: The tip would be $11.88.

Step-by-step explanation: Basically, to find the tip of the bill you need to multiply the total, $74.25 by the tip amount which is 16%. To do this you will first need to convert 16% to a decimal. To find the decimal, divide 16 by 100 to get 0.16. Next, you will need to multiply the total of the bill $74.25 by the decimal 0.16. 74.25 multiplied by 0.16 is 11.88. So, the tip would be $11.88.

Kryger [21]

Answer:

for #1 it's 1, 4, 5, 6

for #2 it's both lines have the same slope

for #3 it's both lines have a different y-intercept

Step-by-step explanation:

#1 explanation: all of them have the y-intercept of -8

ex. y = 3x (- 8) y = 5x (-8) y = 2x (-8) y = (1/3)x (-8)

#2 explanation: both have a slope of (1/4)

#3 explanation: y = (1/4)x there is not y-intercept that we know of and y = (1/4)x - 5 the y-intercept is at -5 therefore the y-intercepts are different

What is the vertex of the quadratic function y=-x²+6x+7? ​
vichka [17]

Answer:

(3,16)

Step-by-step explanation:

Factor the equation to find out that the roots are 7 and -1. The vertex's x will be in the center of these two points, so the center point between 7 and -1 is 3. Continue to substitute the x in the equation with 3 to get the other coordinate for vertex.

Carlos uses a food delivery service to order lunch. He paid $13.75 for lunch, which included the cost of the food and a delivery
Ilya [14]

Answer:

$12.50

Step-by-step explanation:

Let x = the cost of the food without the delivery fee.

The delivery fee can be represented as 0.10x.

Keep in mind that the cost of the food plus the delivery fee equals $13.75.

Therefore, your equation will look like: 13.75 = x + 0.10x

x + 0.1x = 1.10x

So, 13.75 = 1.10x

This means that x = 13.75/1.10

x = 12.5 = $12.50
