Devante has a lunch account in the school cafeteria His starting balance at the beginning of the month is $35.50. The first wook, Davante bought 3 lunches and his account balance was $28.00. The second week. Devante
bought 5 lunches and his account balance was 515 50
In a model that relates the balance of his lunch account as a function of the number of lunches he buys, what does the rate of change represent?
A: the number of lunches he purchases
B: the starting balance of his lunch account
C: the amount of money in his lunch account
D: the amount of money he pays for each lunch
Answer:
D the amount of money he pays for each lunch
Step-by-step explanation:
In each lunch Devante has, he pays 2,50 $ according to:
Money in t = t₀ he has 35,50 $ paid 3 lunches and spent
35,50 - 28 = 7,5
Then the cost of each lunch is 7,5 / 3 = 2,5 $
After that
bought 5 lunches and spent 28 - 15,5 = 12,50
Again 12,5 / 5 = 2,5 $
Now the model for the situation is a straight line with a slope 2,5
In an x , y cartesian system in which y is money in the account and x is the number of lunches, such a straight line will be
y = b - m*x ( b the intercept on y and m the negative slope)
y = 35,50 - 2,5*x
So answering the question is lyrics D the amount of money he pays for each lunch

Step-by-step explanation:
solve the question below
Answer:
The answer is below
Step-by-step explanation:
1) A triangle is a polygon with three sides and three angles. There are different types of triangles such as obtuse, scalene, right angle, equilateral and isosceles triangle.
Given that triangle ABC is right angled and AC = 25 cm = hypotenuse and BC = 15 cm. Using Pythagoras:
AC² = BC² + AB²
25² = AB² + 15²
AB² = 25² - 15²
AB² = 400
AB = √400
AB = 20 cm
Using sine rule:
[tex]\frac{sin(B)}{AC}=\frac{sin(A)}{BC}=\frac{sin(C)}{AB}\\\\But\ \angle B= 90^o(right\ angle)\ hence:\\\\ \frac{sin(B)}{AC}=\frac{sin(A)}{BC}\\\\\frac{sin(90)}{25}=\frac{sin(A)}{15}\\\\sin(A)=\frac{sin(90)}{25}*15\\\\sin(A)=0.6\\\\A=sin^{-1}(0.6)\\\\A=36.87^o[/tex]
2)
Using Pythagoras:
hypotenuse² = 8² + 6²
hypotenuse² = 100
hypotenuse = √100
hypotenuse = 10
Using sine rule:
[tex]\frac{sin(x)}{8}=\frac{sin(90)}{10}\\\\sin(x)=\frac{sin(90)}{10}*8\\\\sin(x)=0.8\\\\x=sin^{-1}(0.8)\\\\x=53.13 ^o[/tex]

What percent of their total goal did Bethany's family donate? F 0.75% G 75% H 2.5% J 0.25%
Answer:
0.75%
Step-by-step explanation:
Total amount to generate at fundraiser = $8000
Amount donated by Bethany family = $60
The percentage of Bethany's donation towards the fundraiser is :
Let percentage = x
x% of 8000 = 60
x/100 * 8000 = 60
0.01x * 8000 = 60
80x = 60
Divide both sides by des by 80
80x / 80 = 60 / 80
x = 0.75

Please answer this correctly without making mistakes
Answer:
16
Step-by-step explanation:
The distance is given by
d = sqrt( (x2-x1) ^2 + ( y2-y1) ^2)
Since the x values are the same
d = sqrt( ( y2-y1) ^2)
d = sqrt( (( -6 - 10)^2))
d = sqrt((-16) ^2)
d = 16
We can also just find the number of squares between the points since the x value is the same.

Answer:

Step-by-step explanation:
10 - -6 = 10 + 6 = 16
John's family visited his grandmother over the weekend. The drive to her house took 2 hours at their usual speed. The trip took 15 minutes longer because traffic was bad and they had to drive 5 mph slower. How many miles away is Johns grandmother's house?
Let the normal speed = x mph
The way to his grandmothers they drove 2x miles
Return trip was 2.25(x-5)
Set those equal and solve for x:
2x = 2.25(x-5)
Simplify:
2x = 2.25x -11.25
Subtract 2.25x from both sides:
-0.25x = -11.25
Divide both sides by-0.25:
X = 45
The usual speed is 45 mph.
So now 2 hours at 45 mph = 90 miles to his grandmothers house
Answer:
90 miles

At soccer practice, Tracey's best kick traveled a distance of 1,200 inches. For how many yards did she kick the ball? Express your answer as a
fraction written in simplest form.
Answer:
100/3 yards
Step-by-step explanation:
36 inches=1 yard, so 1200/36 will equal how many yards 1200 inches is.
Simplify:
1200/36
divide numerator and denominator by 12 and you get 100/3
100/3 yards
Tracey kicks the ball for 100/3 yards.
Given that, at soccer practice, Tracey's best kick travelled a distance of 1,200 inches.
We need to find out for how many yards did she kick the ball.
How to convert inches to yards?Inch-to-yard conversion explanation
So to convert from a value in inches to one in yards, we need to divide by 36. To convert a value in yards to inches, we need to multiply by 36.
Now, the number of yards =1200/36=100/3
Hence, Tracey kicks the ball for 100/3 yards.

The student council needs posters for the Winter Carnival. The print shop charges $15 for each print job. Each poster will cost an additional
$1.35.
Which equation shows the relationship between the number of posters, n, and the total cost, c, in dollars?
O A. c = 1.35n + 15
O B. n = 1.35n + 15
O C. c = 16.35n
O D. n = 16.35c
Answer: A. c = 1.35n + 15
Step-by-step explanation:
Given: Charge for each job = $15
Additional cost per poster = $ 1.35
Total cost = Charge for each job + (Additional cost per poster) (Number of posters) ...(i)
Varaibles:
c= Tota; cost for n posters.
Substitute all values in (i), we get
[tex]c=15+1.35n[/tex]
Hence, the required equation : c = 1.35n + 15
Hence, the correct option is A. c = 1.35n + 15.
