Answer: Around 1000 students would buy a schoo lunch.
Step-by-step explanation:
We know that in one class, 14 students bring lunch from home, and 20 buy lunch in the school. This will be our sample.
In total we have 20 + 14 = 34 students, this will be our 100%.
The percentage of students that bring lunch from home can be estimated as the quotient between the number of students that bring lunch from home and the total number of students, times 100%.
p1 = (14/34)*100% = 41.18%
And the percentage of students that buy lunch at school can be computed in the same way:
p2= (20/34)*100% = 58.82%
Then, out of the 1700 students in middle school, we can estimate that around 58.82% of them will buy lunch in the school.
Then the exact number will be:
N = (58.82%/100%)*1700 = 1000
Around 1000 students would buy a schoo lunch.
Paul Smith pays $50.00 a month for group health insurance. There is a $300 deductible. His medical bills for the last year were $2,600.00. Paul’s insurance company provided payment of 80% of the bills less the deductible. What was Paul’s total cost (including the monthly premium)?
Answer:
$1,360
Step-by-step explanation:
Take the monthly payment of $50 and multiply it by 12 because there is 12 months in a year which is $600. Next subtract $2,600 by your deduction of $300 which is $2,300. Then multiply by 20% because the insurance pays 80% leaving you with 20%, you get $460. Add $460 and $300 because those are the amounts you paid and you get $760. Now add the $600 to the $760 because of the monthly payment. The total comes out to $1,360.

What is the slope?
Simplify your answer and write it as a proper fraction, improper fraction, or integer.
A)1/2
B)7
C)0/4
Answer:
Your answer is A 1/2
Step-by-step explanation:
if we know that y=mx+b and that m is the slope and also that m = rise over run then we see that the rise of this line is 1 and that the run 2.

Answer:
-16/7
Step-by-step explanation:
3(x-2) + 4x = 10(x + 1)
3x-6+4x=10x+10
3x+4x-10x=10+6
-7x=16
X=-16/7
So the answer is -16/7

Answer:
[tex]1.872 \times {10}^{13} [/tex]
Step-by-step explanation:
Simply multiple the values listed
[tex]3.12 \times {10}^{5} \\ \times 6 \times {10}^{7} [/tex]
You can just multiply the values and keep it in scientific notation. No reason to multiply all if it to find the answer.
[tex]18.72 \times {10}^{12} [/tex]
Now we have to put it into scientific notation, simply move the decimal to the left by 1 and add to the exponenet by 1.
[tex]1.872 \times {10}^{13} [/tex]

y-intercept is 1500 and represents the fixed cost.
slope is 100 and represents the number of wristbands sold.
Step-by-step explanation:
Slope is rise over run.
100 up, 1 over.
y-intercept is where the line meets the y-axis, this case 1500. 1500 represents the payment Appleseed spent without selling any wristbands.

kayla is tracking the progress of her plants growth. today the plant is 8 cm high. the plant grows 2 cm per day.
a. write a linear model that represents the height of the plant after d days
b. when will the plant be at a height of 20 cm?
Answer:
30 cm
Step-by-step explanation:
A. Multiply daily rate by number of days and add that to the starting height:
Height = 2d + 8
B. Set height to 20 and solve for d:
20 = 2d +8
Subtract 8 from both sides
12 = 2d
Divide both sides by 2
D = 6
It wall take 6 days.

2.5 x 2.5 x 2.5 - 1.4 x 1.4 x 1.4
(2.5)2+ 2.5 X 1.4 + (1.4)2
Answer:
a) 2.5×2.5×2.5-1.4×1.4×1.4=12.881
b) (2.5)2+2.5×1.4+(1.4)2=31.5
Step-by-step explanation:
yuh multiple 2.5 three times and subtract 1.4 multiple three times. 2.5×2.5×2.5-1.4×1.4×1.4
15.625-2.744=12.881.
b) when opening bracket Yuh multiple the number in the bracket by the number outside the bracket. when bracket is open Yuh can now add, multiple to obtain your answer please
(2.5)2+2.5×1.4+(1.4)2
5+2.5×1.4+2.8
7.5×4.2=31.5

Answer:
60
Step-by-step explanation:
The exterior angles of the polygon are the supplement of the interior angles, so are ...
180° -174° = 6° . . . . measure of each exterior angle
The sum of exterior angles is 360°, so ...
n(6°) = 360°
n = 360°/6° = 60
The polygon has 60 sides.
Answer:
The polygon has 60 sides.
Step-by-step explanation:
Each interior angle = 174°
Each exterior angle = 180° - 174° = 6°
Sum of all exterior angles = 360°
6x = 360° (x = no. of exterior angles)
x = 360°/6
x = 60
If it has 60 exterior angles it has 60 interior angles.

Martha wants to go to band camp this summer that costs $103.50 she has $10 and plans to save $5.50 each week. How many weeks will it take her to save the money? In algebra pls
Answer:
19 weeks
Step-by-step explanation:
You'll be looking for an equation the form of
y=mx+b
Given:
b = $103.50
m = $5.50
x = ? (where x is in weeks)
Next, set y = 0
--> mx+b = 0
Rearrange
x = (-b/m)
Plug in b and m:
x = (-(-103.5)/5.5) = 18.818
Rounding up, it will Martha 19 weeks to save enough money.

Lin has a pet German shepherd that weighs 38 when measured in one unit and 84 when measured in a different unit. which measurement is in pounds, and which is in kilograms?
Given :
Lin has a pet German shepherd that weighs 38 when measured in one unit and 84 when measured in a different unit.
To Find :
Which measurement is in pounds, and which is in kilograms.
Solution :
We know, mass in kg and pounds are related as :
[tex]m_P = 2.2m_{kg}[/tex]
Putting, [tex]m_{kg}=38[/tex] and [tex]m_P=84[/tex] , we get :
LHS = 84
RHS = 2.2 × 38 = 83.6 ≈ 84
Since, LHS = RHS .
Therefore, 38 units is Kg and 84 units in Pounds.
Hence, this is the required solution.
Find the y - intercept of the following equation. Simplify your answer. Y = -10x - 1
Answer
y = 10
Step-by-step explanation:
if they are both negative they cancel each other out so -10 x -1 are both negative it would be 10 so y = 10
