Answer:
B. 585
Step-by-step explanation:
A graph of the scatter plot and line of best fit is attached.
The temperature in this problem will be the independent variable, or x. This is because we are assuming that the number of ice cream cones sold depends on the temperature; this means the number of ice cream cones will be the dependent variable, or y.
This means in our graphing calculator, we will enter temperature in the first list and the number of cones in the second.
After drawing the scatter plot, we run the linear regression; we get the values for a and b in our equation, y = ax+b:
a = 5.08
b = 46.59
This gives us the equation y = 5.08x + 46.59.
Entering our temperature, 106, in for x gives us
y = 5.08(106) + 46.59 = 585.07 ≈ 585

what is the best estimate for the answer to 552.17-48.35?
round each number to the nearest tenth.
Answer:
503.7 is the best estimate when rounding each number to the nearest tenth.
Step-by-step explanation:
Round 552.17 and 48.35 to the nearest tenth. That gives us 552.1 and 48.4 (because 5 makes the number round up). Subtract that, and it gives us 503.7.
Kameko bought a home in Homewood, Illinois, for $230,000. He put down 20% and obtained a mortgage for 25 years at 8%. What's the total interest cost of the loan?
Final answer:
The total interest cost of the loan is $28,999.
Explanation:
To find the total interest cost of the loan, we need to calculate the amount of interest paid over the 25-year period. First, we need to find the amount of the mortgage by subtracting the down payment from the purchase price. 20% of $230,000 is $46,000, so the mortgage is $230,000 - $46,000 = $184,000.
To calculate the interest cost, we can use the formula: Interest Cost = Total Repayment - Principal Amount.
Principal Amount = Mortgage Amount = $184,000.
Number of Payments = Number of years x Number of payments per year = 25 x 12 = 300.
Monthly Interest Rate = Annual Interest Rate / Number of payments per year = 8% / 12 = 0.00667.
Total Repayment = Monthly Payment x Number of Payments = [(Monthly Interest Rate x Principal Amount) / (1 - (1 + Monthly Interest Rate)^(-Number of Payments)) ] x Number of Payments = [(0.00667 x $184,000) / (1 - (1 + 0.00667)^(-300))] x 300 = $526.67 x 300 = $157,001.
Interest Cost = Total Repayment - Principal Amount = $157,001 - $184,000 = $28,999.
Harvey is finding the area that can be divided into 2 trapezoids.the basis of each trapezoid is 14 and 24. The height of each is 8. What is the area of the figure?
Answer:
Area of the figure is 304 sq. units
Step-by-step explanation:
The area is divided into two identical trapezoids of height 8 units and bases 14 and 24 units.
Area of a trapezoid = (1/2) * (Sum of base lengths) * height
So, area of 1 one trapezoid = (1/2)*(14+24)*8=152
The area of the figure is twice the area of the trapezoid.
So, area of figure = 2 * 152 = 304 sq. units
∴ Area of the figure is 304 sq. units

Rose blew h bubbles in two hours. Which algebraic expressions shows how many bubbles she blew in one minute?
Answer:
I believe it is 2 / h = the amount she blew in 1 minute. Hope this helps
Answer:
h / 120
Step-by-step explanation:
2 hours equals 120 minutes.
So h bubbles in 120 minutes is h/120 per minute.
Verification: suppose she blew 240 bubbles in two hours; this would be 240/120 = 2 per minute. That makes 120 per hour and, as expected, 240 in two hours.

Which shows the correct substitution of the values a, b, and c from the equation –2 = –x + x2 – 4 into the quadratic formula?
The correct substitution of the values a, b, and c from the given equation into the quadratic formula is a = 1, b = -1, and c = -2, resulting in the formula x = [1 ± √(1 - 4(1)(-2))] / 2.
For the equation –2 = –x + x² – 4, we need to rewrite it in the standard quadratic equation form ax² + bx + c = 0.
First, rearrange the terms to get x² – x – 4 – (–2) = 0, which simplifies to x² – x – 2 = 0. Here, a = 1, b = -1, and c = -2.
Using the quadratic formula, x = [-b ± √(b2 - 4ac)] / 2a, we substitute a, b, and c:
a = 1b = -1c = -2Need help, WILL GIVE BRAINLIEST!!!
Part A: x=2
This would make both perimeters equal to 24.
Part B: No solution.
You cannot make x equivalent to anything but 2, or the square would not be real. All four sides of the square must equal 6. This would make the area 36 units squared. If x was 2 for the rectangle, the area would be 20. It is impossible to make them equal. Tell me if I'm wrong, though.

Tickets for a choir concert cost $3 for students and $5 for adults. The choir director wants to sell at least $1500 worth of tickets to this concert. She knows that 226 students purchased a ticket. Enter the minimum number of adults that need to purchase a ticket to raise at least $1500.
Answer: 164.4 or 165
Step-by-step explanation: So, you do 226 x 3 and you get $678. So now that you know that you have $678 worth of student tickets, you want to find how much more you need for the adult tickets, so you do $1500-$678, and you get $822. Divide it by 5 and you get 164.4, so you wanna sell about 165 tickets. Check your work by multiplying 5 by 165 and you get $825, which meets your $1500 minimum
After calculating the revenue already obtained from the student tickets sold, the remaining revenue needed to reach $1500 is found. This amount is divided by $5 (the cost of an adult ticket) to find the minimum number of adult tickets needed. Since you can't sell fractions of tickets, we round up to the next whole number, which is 165 adult tickets.
Explanation:The first step to solve this problem is to calculate how much revenue has already been raised from the student tickets sold, which is $3 x 226 = $678. Then subtract this amount from the total revenue target of $1500, which gives $1500 - $678 = $822.
The choir director now needs to raise $822 from selling adult tickets. As each adult ticket costs $5, we can calculate the minimum number of adult tickets that need to be sold by dividing the amount of revenue needed by the price of an adult ticket. This is $822 / $5 = 164.4.
Since you can't sell .4 of a ticket, we'll need to round up to the next whole number, giving a minimum of 165 adult tickets that need to sell in order to reach the revenue target.

Peter had a 12:00 noon appointment that was 60 miles from his home. He drove from his home at an average rate of 40 miles per hour and arrived 15 mins late. At what time did Peter leave home
Answer:
10:45
Step-by-step explanation:
v...speed = 40 mph
s...distance = 60
t...time
if he was 15 min late he arrived at 12:15
v=s/t => t=s/v
t = 60/40 = 1.5 h = 1h and 30 min
if he arrived at 12:15 and he was driving for an hour and a half just substract
12:15 - 1:30 = 11:15 - 0:30 = 10:45

Find all the whole values of a for which the solution of the equation ax = 6 is a whole number.
Answer:
[tex]a=1,\ 2,\ 3,\ 6.[/tex]
Step-by-step explanation:
A whole number is any number of a set [tex]\{0,\ 1,\ 2,\ 3,...\}[/tex]
The equation [tex]ax=6[/tex] has a solution [tex]x=\dfrac{6}{a},\ a\neq 0.[/tex]
If [tex]a=1,[/tex] then [tex]x=\dfrac{6}{1}=6[/tex] is a whole number.
If [tex]a=2,[/tex] then [tex]x=\dfrac{6}{2}=3[/tex] is a whole number.
If [tex]a=3,[/tex] then [tex]x=\dfrac{6}{3}=2[/tex] is a whole number.
If [tex]a=6,[/tex] then [tex]x=\dfrac{6}{6}=1[/tex] is a whole number.

Line AB passes through points A(–6, 6) and B(12, 3). If the equation of the line is written in slope-intercept form, y = mx + b, then m = –1/6.
and b = ?
Put the value of slope to the equation of the function:
[tex]y=-\dfrac{1}{6}x+b[/tex]
Put the coordinates of the point B(12, 3) to the equation:
[tex]3=-\dfrac{1}{6}(12)+b[/tex]
[tex]3=-2+b[/tex] add 2 to both sides
[tex]5=b[/tex]
Answer: b = 5Answer:
The value of b is 5.
Step-by-step explanation:
Consider the provided information.
It is given that the slope intercept form is, y = mx + b
Where m is the slope and b is the y intercept.
Also, it is given that the slope of the line is -1/6.
Line AB passes through points A(–6, 6) and B(12, 3).
That means Point A and B must satisfy the equation of line.
Substitute [tex]m=\frac{-1}{6}, x=-6\ \text{and}\ y = 6[/tex] in slope intercept form:
[tex]6=\frac{-1}{6}\times(-6)+b[/tex]
[tex]6=1+b[/tex]

Step-by-step explanation:
We are given the following equation for which we have to solve for y:
[tex]7y+44=12y+11[/tex]
So first of all, we will rearrange the terms by putting the like terms together (variables on one side of the equation and constants on the other side) to get:
[tex]12y-7y=44-11[/tex]
Then solving for y:
[tex]5y=33\\\\y=\frac{33}{5}[/tex]
Therefore, the value of y is equal to [tex]y=6\frac{3}{5}[/tex] (rewriting y in a mixed fraction form).
