if you normally sell 72 tacos for every 50 people that stop by your taco truck, how many tacos would you sell if 275 people came to your truck?
Answers
Answer:
396 formula 72/50 x 275 please give brainliest
Step-by-step explanation:
Answer:
396 tacos
Step-by-step explanation:
for 50 people 72 tacos were sold
for 275 people a tacos were sold
50 people = 72 tacos
275 people= a tacos
cross multiplying
50 × a = 72 × 275
50a = 19800
diving both sides by 50
50a ÷ 50= 19800÷50
a=396 tacos
therefore if 275 people came,396 tacos will be sold

The independent variable is found to be d.
What is an independent variable?An independent variable can be defined as a variable that can take any value which implies it is not dependent on any other variables.
The example can be given as y = x + 2, here x is an independent variable.
The given algebraic expression w = 7d + 13
There are two terms 7d and 13.
Here, the variable term is 7d.
And, the value of w depends on d which implies that d is the independent variable.
Hence, in the given expression the independent variable is d.

If seven people meet each other and each shake hands only once with each of the others, how many handshakes happened?
Answers
Answer:
alright so every person shook 7 people's hands so 7x and there are 7 people so 7(7) and that is 49
There are 21 handshakes happened.
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
There are 7 people meet each other and each shake hands only once with each of the others.
Now,
We know that;
Number of handshakes = n (n - 1) / 2
Here, Number of people = 7
So, we can formulate;
Number of handshakes = n (n - 1) / 2
= 7 (7 - 1) / 2
= 7 × 6 / 2
= 7 × 3
= 21
Thus, There are 21 handshakes happened.

8th/9th-95 POINTS+BRAINLIEST!!!!!!!! How do you write a quadratic equation in vertex form? Please explain the steps in simple language and use y=x²+6x+16 as an example.
Answers
Answer:
In vertex form: y = 1(x - (-3))² + 7
Vertex: Minimum (-3, 7)
Explanation:
Vertex form: y = a(x - h)² + k
Completing square (rules) :
1st rule: (x + d)² = x² + 2dx + d² and (x - d)² = x² - 2dx + d²
2nd rule: x² + 2dx = (x + d)² - d² and x² - 2dx = (x - d)² - d²
Given equation:
y = x² + 6x + 16
y = x² + 2(3)x + 3² + 7
y = (x + 3)² + 7
Into vertex form:
y = 1(x - (-3))² + 7
From this identify:
a = 1, h = -3, k = 7
Solution, vertex of this equation: Minimum (-3, 7)

Answers
Simplify 64/52
64/52=16/13
To get 16/13, you have to cancel out the common factor which is 4.

13•16=208
208 / 104 = 2
Therefore,
x=2
Answer: 2
Step-by-step explanation: This is incredibly simple first we can match the denominators, 4*13 = 52 and that means we have to do that to numerators to, 8x*4 = 32x so now our equation is 32x/52 = 64/52 and as we know 32*2 = 64 so that means x = 2.

For each ride, a taxi service charges an initial fee plus an additional fee based on the number of kilometers of the trip. The graph shows the cost for taxi rides. Select a true statement. The rise is 4 while the run is 2. The selection of answers are:
A: The slope is 2.1. This means that each kilometer costs $2.10.
B: The slope is 5. This means that each kilometer costs $5.
C: The y-intercept is 2.1. This means that the initial fee is $2.10.
D: The y-intercept is 5. This means that the ride lasts 5. kilometers.
Which one is right and why?
Answers
THIS MIGHT NOT BE WHAT YOU ARE LOOKING FOR AND MIGHT NOT BE CORRECT! READ FIRST!
The answer is A. The slope of the line is rise/run = 4/2 = 2.1. This means that each kilometer costs $2.10. The y-intercept is 2.1, which means that the initial fee is $2.10. So the correct statement is: The slope is 2.1. This means that each kilometer costs $2.10.
The other statements are incorrect. The slope is not 5, so each kilometer does not cost $5. The y-intercept is not 5, so the ride does not last 5 kilometers. The y-intercept is the value of the function when the input is 0, which in this case is the initial fee of $2.10.
