Shawn has a budget of $50 per month to spend on bus fare. He made a table showing the total amount of bus money he will have left after the given number of rides.
Number of rides 0 9 18 27
Total amount of bus money left ($) 50 41 32 23
Which equation, in standard form, represents the relationship between the number of bus rides, x, and the amount of bus money Shawn will have left, y?
50x = y
x + y = 50
50y = x
Answers
Answer:
x+y = 50
Step-by-step explanation:
We can find the slope of the line
m = (y2-y1)/(x2-x1)
= (50-41)/(0-9)
= 9/-9
=-1
We can use the point slope form of the equation to make an equation for a line
y-y1 = m(x-x1)
y-50 = -1(x-0)
y-50 = -x
To get it in standard from, subtract y from each side
y-y-50 = -x-y
-50 = -x-y
Multiply each side by -1
50 = x+y
x+y = 50
The equation representing the relationship between the number of bus rides and the amount of bus money is [tex]\( x + y = 50 \)[/tex]. The option (a) is correct.
The amount of bus money Shawn will have left is [tex]y[/tex].
Representing the relationship between the number of bus rides [tex]\( x \)[/tex] .
We can see that for every 9 rides, Shawn's remaining bus money decreases by $9.
This suggests that the cost of each ride is $1 (since $9 divided by 9 rides equals $1 per ride).
We know that Shawn starts with $50 and each ride costs $1.
So, after [tex]\( x \)[/tex] rides, Shawn will have spent [tex]\( x \)[/tex] dollars.
So, the equation is :
[tex]\[ y = \text{Initial amount} - \text{Cost per ride} \times \text{Number of rides} \][/tex]
[tex]\[ y = 50 - 1 \times x \][/tex]
[tex]\[ y = 50 - x \][/tex]
This equation can be rearranged to standard form, which is [tex]\( Ax + By = C \)[/tex] , where [tex]\( A \), \( B \), and \( C[/tex] are constants.
For our equation,[tex]\( A = -1 \), \( B = 1 \) , and \( C = 50 \)[/tex] , so in standard form, it is :[tex]\[ -x + y = 50 \][/tex] .
We can multiply the entire equation by -1 to get :
[tex]\[ x - y = -50 \][/tex]
[tex]\[ x + y = 50 \][/tex]
This is the equation in standard form that represents the relationship between the number of bus rides, [tex]\( x \)[/tex], and the amount of bus money Shawn will have left, [tex]\( y \)[/tex].
Therefore, the correct answer is [tex]\( x + y = 50 \)[/tex] .
The complete question is:

Identify an equation in point slope form for the line perpendicular to y = -1/3 x - 6 that passes through (-1,5)
Answers
Answer:
y + 1 = 3(x - 5) Answer
Step-by-step explanation:
Find the slope of the perpendicular line.
m1 * m2 = - 1
m1 = - 1/3
m2 is the slope of the perpendicular
(-1/3) * m2 = - 1 Multiply both sides by -3
-(3)(-1/3) * m2 = -1 * -3
m2 = 3
The slope of the perpendicular line is 3
Find the equation of the line.
m = (y - y1)/(x -x1)
y - y1 = m(x - x1) is the equation of the line.
y1 =5
x1 = - 1
(y - - 1) = 3(x - 5)
y + 1 = 3(x - 5) Answer
Ben, Cam, and Justin are lumberjacks. The number of trees they chop down is given by b+2c+3jb+2c+3j where b is the number of hours Ben spends chopping, c is the number of hours Cam spends chopping, and j is the number of hours Justin spends chopping.
How many trees do they chop down after Ben spends 88 hours chopping, Cam spends 33 hours chopping, and Justin spends 44 hours chopping?
Answers
Answer:
748 trees PLEASE GIVE BRAINLIEST
Step-by-step explanation:
b + 2c + 3jb + 2c + 3j =
88 + 2(33) + 3(44)(88) + 2(33) + 3(44) =
88 + 66 + 396 + 66 + 132 = 748 trees
After Ben spends 88 hours chopping, Cam spends 33 hours chopping, and Justin spends 44 hours chopping, they chop down a total of 286 trees.
To find the total number of trees chopped down, we'll use the given formula: ( b + 2c + 3j ), where ( b ) is the number of hours Ben spends chopping, ( c ) is the number of hours Cam spends chopping, and ( j ) is the number of hours Justin spends chopping.
Given that Ben spends 88 hours chopping ( b = 88 ), Cam spends 33 hours chopping ( c = 33 ), and Justin spends 44 hours chopping ( j = 44), we can substitute these values into the formula.
Plugging in the values:
[tex]\[ \text{Total trees} = 88 + 2(33) + 3(44) \][/tex]
Now, we calculate each term:
[tex]\[ 2(33) = 66 \][/tex]
[tex]\[ 3(44) = 132 \][/tex]
Then, we add up all the terms:
[tex]\[ \text{Total trees} = 88 + 66 + 132 \][/tex]
[tex]\[ \text{Total trees} = 286 \][/tex]
So, after Ben spends 88 hours chopping, Cam spends 33 hours chopping, and Justin spends 44 hours chopping, they chop down a total of 286 trees.

Women athletes at the a certain university have a long-term graduation rate of 67%. Over the past several years, a random sample of 42 women athletes at the school showed that 23 eventually graduated. Does this indicate that the population proportion of women athletes who graduate from the university is now less than 67%? Use a 1% level of significance.
Answers
Answer:
The null and alternative hypotheses are:
[tex]H_{0}: p=0.67[/tex]
[tex]H_{a} : p <0.67[/tex]
Under the null hypothesis, the test statistic is:
[tex]z=\frac{\hat{p}-p}{\sqrt{\frac{p(1-p)}{n} } }[/tex]
Where:
[tex]\hat{p}= \frac{23}{42} = 0.5476[/tex]
[tex]\therefore z = \frac{ 0.5476 -0.67}{\sqrt{\frac{0.67(1-0.67)}{42} }}[/tex]
[tex]=\frac{-0.1224}{0.072555398}[/tex]
[tex]=-1.69[/tex]
Now, we have to find the left tailed z critical value at 0.01 significance level using the standard normal table. The z critical value at 0.01 significance level is:
[tex]z_{critical} = -2.33[/tex]
Conclusion: Since the test statistic does not fall in the critical region, therefore, we fail to reject the null hypothesis, and conclude that there is not sufficient evidence to say that the population proportion of women athletes who graduate from the university is now less than 67%.
Answer: No
Step-by-step explanation:By considering the given information , the null and the alternative hypotheses will be :-
[tex]H_0: p=0.67\\\\H_a: p<0.67[/tex]
Since the alternative hypotheses is left-tailed , so the test applied here is left-tailed.
Sample size : n= 42
The sample proportion of graduated : [tex]\hat{p}=\dfrac{23}{42}\approx0.55[/tex]
The test statistic for population proportion :-
[tex]z=\dfrac{\hat{p}-p}{\sqrt{\dfrac{p(1-p)}{n}}}[/tex]
i.e. [tex]z=\dfrac{0.55-0.67}{\sqrt{\dfrac{0.67(1-0.67)}{42}}}\approx-1.65[/tex]
The p-value : [tex]P(z<-1.645)=0.0494715[/tex]
Since the p-value is greater than the significance level, then we do not reject the null hypothesis.
Hence, it does not give enough evidence to indicate that the population proportion of women athletes who graduate from the university is now less than 67%.

Jasmine borrowed $15,000 for 8 years and she paid $6,600 in interest. What was the interest rate for Jasmine's loan?
A) .055%
B) 6%
C) 3.25%
D) 5.5%
Answers
Answer:
D) 5.5%
Step-by-step explanation:
To find the interest rate, use the equation: I = prt
I = Interest = $6,600
p = principal = $15,000
r = rate = unknown
t = time = 8 years
Now plug the numbers into the equation.
6,600 = 15,000 * r * 8
6,600 = 120,000 * r
Now isolate the variable by dividing both sides of the equation by 120,000.
0.055 = r
Now change the rate to a percent by moving the decimal point 2 digits to the right.
5.5% = r OR r = 5.5%

what two numbers have 90 as their lcm and 810 as their product
Answers
Answer:
9,90
Step-by-step explanation:
Since their lack is 90, we can divide 810 by 90 and get 9. So 9 is their common factor. So 9 and 90.
To find two numbers with 90 as their LCM and 810 as their product, prime factorize 810, and choose two numbers from the prime factors that satisfy the conditions.
Explanation:The question asks to find two numbers that have 90 as their lowest common multiple (LCM) and 810 as their product.
To find these numbers, we need to first prime factorize 810. The prime factorization of 810 is 2 x 3 x 3 x 3 x 3 x 5.
Now, we need to choose two numbers from these prime factors such that their product is 810 and their LCM is 90. Since 90 = 2 x 3 x 3 x 5, we can choose 3 x 3 x 2 = 18 and 5 as the two numbers.

Suppose you had $100 in a savings account and the interest rate was 2% per year. After 5 years, how much do you think you would have in the account if you left the money to grow?
Answers
Answer:
$110
Step-by-step explanation:
A = P(1 + r/n)ⁿ⁺
A = 100(1 + .02/1)¹⁽⁵⁾
A = 100(1.10)
A = $110
Using the simple interest formula, you can calculate that after 5 years at an annual interest rate of 2%, an initial deposit of $100 in a savings account would grow to $110.
Explanation:The subject of this question is simple interest, which is important in Mathematics. To calculate how much money would be in your account after 5 years with an interest rate of 2% per annum, you would utilize the simple interest formula:
Interest = Principal x Rate x Time (I = PRT)
The principal (P) is the initial amount of money, which is $100. The rate (R) is the interest rate per period. The time (T) represents the number of periods.
In our case: The principal is $100, the rate is 2% (or 0.02 in decimal form), and the time is 5 years. Substituting these values into the formula gives. Interest = $100 x 0.02 x 5 = $10. After 5 years, you are entitled to $10 interest. This means the total amount in your account will be your initial principal plus the earned interest: $100 + $10 = $110.

The account after 20 years is $73798.8.
Step-by-step explanation:
Given : James and Terry open a savings account that has a 2.75% annual interest rate, compounded monthly. They despoit $400. Into the account each month.
To find : How much will be in the account after 20 years ?
Solution :
Using monthly payment formula,
[tex]M=\frac{\text{Amount}}{\text{Discount factor}}[/tex]
Discount factor is [tex]D=\frac{1-(1+i)^{-n}}{i}[/tex]
Substitute in the formula,
[tex]\text{Amount}=M\times \frac{1-(1+i)^{-n}}{i}[/tex]
Where, M=$400 amount deposited monthly
r= 2.75%=0.0275 is the interest rate
[tex]i=\frac{0.0275}{12} =0.00229[/tex]
t=20 years is the time
[tex]n=12\times 20=240[/tex]
Substitute the value,
[tex]\text{Amount}=400\times \frac{1-(1+0.00229)^{-240}}{0.00229}[/tex]
[tex]\text{Amount}=400\times \frac{1-0.5775}{0.00229}[/tex]
[tex]\text{Amount}=400\times 184.497[/tex]
[tex]\text{Amount}=73798.8[/tex]
Therefore, the account after 20 years is $73798.8.

There is 5 gallons of sap produced that day.
Hope this helped!
Answer:
5 gallons
Step-by-step explanation:
Number of x's on 1/4 = 3
So, amount of sap trees produce that day = 3/4
Number of x's on 3/8 = 2
So, amount of sap trees produce that day = 2 × 3/8 = 3/4
Number of x's on 5/8 = 4
So, amount of sap trees produce that day = 4 ×5/8 = 5/2
Number of x's on 1 = 1
So, amount of sap trees produce that day = 1 × 1 =1
Therefore,
total amount of sap the trees produce = amount of sap trees produce based on number of x's on 1/4 + amount of sap trees produce based on number of x's on 3/8 + amount of sap trees based on number of x's on 5/8 + amount of sap trees based on number of x's on 1 = [tex]\frac{5}{2}+\frac{3}{4}+\frac{3}{4}+1=\frac{10+3+3+4}{4}=\frac{20}{4}=5\,\,gallons[/tex]
Which of the following angles is not coterminal with the other three? Question 15 options: 231° 51° –129° 591°
Answers
Answer:
51
Step-by-step explanation
Given angles can break like this :
231 = 180 +51
51= 0+51
-129= -180+51
591= 360+180+51
so angles 231, -129 and 591 corresponds to the same terminal while 51 is not related to the particular quadrant . so 51 is not co-terminal with the other three angles .
if the formula for the perimeter of a rectangle is p=2l+2w, what is the formula for w in terms of p and l
Answers
Answer:
(p-2l)/2 = w
Step-by-step explanation:
p=2l+2w
We want to solve for w.
The first step is to subtract 2l from each side
p-2l=2l-2l+2w
p-2l=2w
Then we will divide each side by 2 to isolate w
(p-2l)/2 = 2w/2
(p-2l)/2 = w
Myron is cooking meat. The double number line shows that he needs 1 2 12 hours to cook 5 5 kilograms of meat. 0 0 5 5 Meat Meat (kg) (kg) 0 0 1 2 12 Time Time (hours) (hours) Based on the ratio shown in the double number line, how long does Myron need to cook 3 3 kilograms of meat?
Answers
Answer: 7 hours 12 minutes
Step-by-step explanation:
Let he needs x hours to make 1 kg of meat.
Therefore, time taken in making 5 kg of meat = 5 × x = 5x hours.
But, According to the question,
He needs 12 hour to cook 5 kg of meat.
Thus, 5 x = 12
⇒ [tex]x = \frac{12}{5}[/tex] ( By dividing both sides by 5 )
⇒ He needs [tex] \frac{12}{5}[/tex] hours to make 1 kg of meat.
⇒ The time taken to cook 3 kg of meat = [tex]3\times \frac{12}{5}=\frac{36}{5} [/tex]
= [tex]7\frac{1}{5}[/tex] hours ⇒ 7 hours 12 minutes
Hence, He needs 7 hours 12 minutes time to cook 3 kg of meat.
After calculating, we determined that Myron needs 54 minutes to cook 3 kilograms of meat.
This problem can be solved by setting up a proportion since it involves a direct ratio between the weight of meat and the cooking time.
The given ratio is 1 1⁄2 hours for 5 kilograms of meat (1:5 ratio). To find the time needed for 3 kilograms of meat, use the proportion:
5 kg :- 1 1⁄2 hours
3 kg :- x hours
Solving for x yields the following:
5 kg / 3 kg = 1 1⁄2 hours / x hours
x = (1 1⁄2 hours × 3 kg) / 5 kg
Converting 1 1⁄2 hours to minutes (90 minutes) and then performing the multiplication and division:
x = (90 minutes × 3) / 5
x = 270 minutes / 5
x = 54 minutes
Thus, Myron needs to cook 3 kilograms of meat for 54 minutes.
