Mrs. Jones decided to buy some pencils for her class. She bought 4 packages of pencils, and each package contained 57 pencils. There are 19 students in her class and she divided up the pencils so that each student had the same amount of pencils. If there were no pencils left over, how many pencils did each student get?
Answer:
The correct answer is 19 pencils.
Step-by-step explanation:
First, we have to multiply
57 x 4 = 228
Second, we have to divide
228 ÷ 19 = 12
Lastly, we write the answer in a complete sentence.
Each student got 19 pencils if there were no pencils left over.
Hope This Helps!
Answer:
Each student got 12 pencils
Step-by-step explanation:
57 times 4 = 228

Step-by-step explanation:
1. Write a quadratic equation for the parabola that passes through the
point (2, -3) with roots (-6, 0) and (4,0).
The quadratic equation with the given conditions is:
[tex]f(x) = \frac{3}{16}(x^2 + 2x - 24)[/tex]
The standard form of a quadratic equation with roots [tex](x_1,0)[/tex] and [tex](x_2,0)[/tex] is given by:
[tex]f(x) = a(x - x_1)(x - x_2)[/tex]
In which a is the leading coefficient.
In this problem, the roots are [tex]x_1 = -6, x_2 = 4[/tex], thus:
[tex]f(x) = a(x - (-6))(x - 4)[/tex]
[tex]f(x) = a(x + 6)(x - 4)[/tex]
[tex]f(x) = a(x^2 + 2x - 24)[/tex]
It passes through point (2,-3), which means that when [tex]x = 2, f(x) = -3[/tex], and this is used to find a.
[tex]a(2^2 + (2)(2) - 24) = -3[/tex]
[tex]-16a = -3[/tex]
[tex]a = \frac{3}{16}[/tex]
Thus, the equation is:
[tex]f(x) = \frac{3}{16}(x^2 + 2x - 24)[/tex]

javeria left home at 7:10, she walked for 15 mins to the station and walked for 10 mins for a train. she then travelled by train for 45 mins.
at what time did javeria get off the train?
a) 8:25
b) 8:20
c) 8:15
d) 8:10
Answer: Its B 8:20
Step-by-step explanation:
U get this by adding the 15 minutes to the 7:10 and then u get 7:25 then you add the 10 and u get 7:35 then you add the 45 and you get 8:20
The time at which Javeria gets off the train is 8:20 thus option (b) is correct.
What are work and time?Work is the completion of any task for example if you have done your homework in 5 hours then you have done 5 hours.
Another example of work is that if you have done your food by 1 hour it means your work duration is 1 hour so work is basically the time duration of any task which you have done.
As per the given,
Javeria left home at 7:10.
Add 15 + 10 + 45 = 70 minutes.
70 minutes = 1 hour + 10 minutes or 1:10
Add into 7:10 as
7 + 1:10 + 10
8:20
Hence "The time at which Javeria gets off the train is 8:20".

Use the figure to find the measures of the numbered angle.
Answer:
angle 1 = 61°
angle 2 = 119°
angle 3 = 61°
angle 4 = 119°
angle 5 = 119°
angle 6 = 61°
angle 7 = 119°
Step-by-step explanation:
angle 1 = 61° (corresponding angles are always equal)
angle 1 + angle 2 = 180° (linear pair)
=> 61° + angle 2 = 180°
=> angle 2 = 180° - 61° = 119°
angle 2 = 119
angle 1 = angle 3 = 61° (vertically opposite angles are equal)
angle 2 = angle 4 = 119° (vertically opposite angle are equal)
angle 4 = angle 5 = 119° (interior opposite angles are equal)
angle 6 = 61° (vertically opposite angles are equal)
angle 5 = angle 7 = 119° (vertically opposite angles are equal)

Maria added 45,273 and 35,687 and got a sum of 70,960 is Maria’s answer reasonable? Explain.
Answer: No
Step-by-step explanation: Tell Maria to do the problem again.
If Maria added 45,273 and 35,687 and got a sum of 70,960 : Yes, Maria's answer is reasonable.
What is sum?When we add 45,273 and 35,687 we have:
45,273 + 35,687 = 80,960
Maria's response, however, is 70,960, which is 10,000 below the accurate total. This indicates that Maria most likely added incorrectly.
The rationality of the response is demonstrated by the fact that Maria's answer is considerably less than the right answer. This 10,000-difference discrepancy is not a trivial error and suggests that an addition error most likely occurred.
