Answer:
f(100) = 160.
Step-by-step explanation:
Linear function:
The equation of a linear function has the following format:
[tex]y = mx + b[/tex]
In which m is the slope(how much f(x) changes when x changes by 1) and b is the y-intercept(value of f(x) when x = 0).
Finding the slope:
Suppose we have two points. The slope is the change in the output divided by the change in the input.
In this question, we have points (45,50) and (60,80).
Change in the output: 80 - 50 = 30
Change in the slope: 60 - 45 = 15
Slope: 30/15 = 2
So
[tex]y = 2x + b[/tex]
Point (45,50)
This means that when [tex]x = 45, y = 50[/tex]. We use this to find the value of b.
[tex]y = 2x + b[/tex]
[tex]50 = 2(45) + b[/tex]
[tex]b = -40[/tex]
So
[tex]y = 2x - 40[/tex]
With y = f(x)
What is the value of f(100)?
This is y when x = 100. So
[tex]f(100) = 2(100) - 40 = 200 - 40 = 160[/tex]
f(100) = 160.
Is this 40%? If not, what's the answer? Thanks!

It is!

A family dines in a popular franchise restaurant. At the end of the meal, they decide to leave their server a monetary tip that is equal to 20% of the total bill amount, $60.50. How much will the family leave their server as a tip?
A family dines in a popular franchise restaurant. They plan to use a coupon that will give them a discount of 15% off of their total dinner bill, not including applicable sales tax or their server’s tip. If the family’s dinner bill totaled $34.00 before tax and tip, how much money will they save by using the coupon?
A family dines in a popular franchise restaurant. They plan to use a coupon that will give them a discount of 10% off of their total dinner bill, not including applicable sales tax or their server’s tip. The bill totals $157.30 before tax and tip. What is the new total after the server applies the 10% off coupon?
A family of eight dines in a popular franchise restaurant. The restaurant has a policy of automatically including a standard tip to the final bill for parties larger than six people. The bill for the meal included a total of $58.25 in food and beverage sales, plus a standard tip of $10.49. What percent of the food and beverage sales does the restaurant consider to be a standard tip for parties larger than six?
A family dines in a popular franchise restaurant that has a policy of automatically including a 20% tip on all food and beverage sales before coupon discounts are applied. What is the family’s total bill amount if their food and beverages totaled $94.20 and they used a 15% off coupon? (HINT: Create more than one model.) DONT ANSWER THE QUESTION JUST PUT THE EQUATIONS
Answer:
A) t=0.2(60.5)
B) d=0.15(34)
C) t=0.9(157.3)
D) p=100(10.49/58.25)
E) t=0.85(94.2+0.2(94.2))
Step-by-step explanation:
A)
Let the tip be represented by t. The tip is 20% of $60.50:
t=0.2(60.5)
B)
Let the money they save be represented by d. Their discount is 15% of $34:
d=0.15(34)
C)
Let the new total be represented by t. Their discount is 10%, so they will only be paying 90% of $157.30t:
t=0.9(157.3)
D)
Let the percentage be represented by p. The tip is $10.49, to find this as a precent of the $58.25 bill, divide the tip by the bill and multiply by 100:
p=100(10.49/58.25)
E)
First find the total after the tip but before the coupon.
Their tip is 20% of $94.20, and their total before the coupon is $94.20 plus the tip: 94.2+0.2(94.2)
Now find their final total.
Let the final total be represented by t. The discount is 15%, so they will only be paying 85% of the total after tip:
t=0.85(94.2+0.2(94.2))

Lowest common multiple for 3ab; 6b2; 7a3b
Answer:
L.C.M = 2 × 7 = 14
Step-by-step explanation:
3ab = 3 × a × b
6b² = 2 × 3 × b × b
7a³b = 7 × a × a × a × b
L.C.M = 2 × 7 = 14
Thus, Lowest common multiple for 3ab; 6b²; 7a³b is 14

Convert 49° Celsius to degrees Fahrenheit using the following formula: F = {C+32 O A. 506.5°F OB. 196.2°F C. 94.6°F OD. 2237°F O E. 120.2°F
Answer:
Step-by-step explanation:
F = 9/5C + 32
Putting value
9/5(49) + 32
88.2 + 32
= 120.2°F
Option E is the correct answer
The Celsius temperature 49 in Fahrenheit is 120 F.
To convert Celsius to Fahrenheit, you can use the formula:
F = (C × 9/5) + 32
Let's calculate the conversion using the given Celsius value:
C = Celsius temperature
F = (C × 9/5) + 32
F= (49 x 9/5)+ 32
F= 88.2 + 32
F = 120.2 F
Thus, Celsius temperature 49 in Fahrenheit is 120 F.

Answer:
1.6
Step-by-step explanation:
So, first, write down the number of jokers in each deck of cards.
That would be: 0, 1, 2, 2, 3

Answer:
d. √74 units
Step-by-step explanation:
The distance formula is useful for finding the length of a line segment.
d = √((x2 -x1)^2 +(y2 -y1)^2)
Filling in the point coordinates L(-5, -3) and M(0, 4), we find the length of LM to be ...
LM = √((0-(-5))^2 +(4 -(-3))^2) = √(25 +49)

Answer:
Probability in Maths:-
Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one. Probability has been introduced in Maths to predict how likely events are to happen.
Formula for Probability:-
The probability formula is defined as the possibility of an event to happen is equal to the ratio of the number of favourable outcomes and the total number of outcomes.
Probability of event to happen P(E) = Number of favourable outcomes/Total Number of outcomes
Probability refers to a possibility that deals with the occurrence of random events also can be state as all the events occurring need to be 1.
