Answer:
N=+24,-24
Step-by-step explanation:
Well this is a quadratic equation and we can make further deductions using it's discriminant
b²-4ac=0
N²-4(1×144)=0
N²-576=0
N²=576
N=√576
N=+24,-24
The possible values of N are +24, and -24 if both roots of x² + Nx + 144 are equal to each other.
What is a quadratic equation?Any equation of the form [tex]\rm ax^2+bx+c=0[/tex] where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic equation.
It is given that:
The quadratic equation is:
x² + Nx + 144 = 0
Discriminant will be zero:
D = 0
b²-4ac=0
N²-4(1×144)=0
N²=576
N=√576
N=+24,-24
Thus, the possible values of N are +24, and -24 if both roots of x² + Nx + 144 are equal to each other.

Step-by-step explanation:
1760 upper primary pupils took part in a sports meet in 2014. This was decreased of 20% when compared to 2015. The number of the upper primary pupils who took part in 2016 increased by 5% when compared to 2015. How many upper primary pupils took part in the sports meet in 2016?
Answer:
Number of upper primary pupils who took part in the sports meet in 2016 is 1478.
Step-by-step explanation:
Total number of upper primary pupils who took part in the sports meet in 2014 is 1760. It was decreased of 20% compared to 2015.
So that,
20% of 1760 = [tex]\frac{20}{100}[/tex] x 1760
= 0.2 x 1760
= 352
Number of upper primary pupils who took part in the sports meet in 2015 = 1760 - 352
= 1408
Also,
5% of 1408 = [tex]\frac{5}{100}[/tex] x 1408
= 0.05 x 1408
= 70.4
Number of upper primary pupils who took part in the sports meet in 2016 = 1408 + 70.4
= 1478.4
With an increase of 5% compared to 2015, the number of upper primary pupils who took part in the sports meet in 2016 is 1478.

Answer:
For the second question, 4 busses and 3 cars.
Step-by-step explanation:
It's really simple actually, but sorry I can't come up with an equation. You can just add or multiply students per bus and students per car until you get to 195. Each bus can hold 45 students, so 45 x 4 = 180. Each car can hold 5 students, so 5 x 3 = 15. In total, 15 + 180 = 195 students.

Colin was helping his uncle clean up a construction site. Colin's job was to make a neat stack of scrap wood. Each piece of wood was 1 3/8 inches thick. At the end if the day, Colin's stack was 57 3/4 inches tall. How many pieces of wood were in Colin's stack?
Answer:
a) 1/2 of an energy bar
b) 42 pieces
Step-by-step explanation:
a) Here, Franklin are 3/4 of an energy bar while Trey are 2/3 of what Franklin ate
The fraction are by Trey is 2/3 * 3/4 = 6/12 = 1/2
b) To find the number of pieces of wood present, we will need to divide the height of Colin’s stack by the thickness of each piece of wood
Mathematically, that will be;
57 3/4 divided by 1 3/8
= 231/4 * 8/11 = 42 pieces

can the sides of triangle have lengths 4, 10, and 1? yes or no
Answer:
Yah, it can as long as it has three sides
Answer:
Yes because..... (see explanation)
Step-by-step explanation:
Triangle Inequality Theorem. The sum of the lengths of any two sides of a triangle is greater than the length of the third side.
According to the first triangle inequality theorem, the lengths of any two sides of a triangle must add up to more than the length of the third side. This means that you cannot draw a triangle that has side lengths 2, 7 and 12, for instance, since 2 + 7 is less than 12.

On Saturdays, Eve earns $14 per hour for yard work and an extra amount for dog walking. Look at the table. Choose the linear function f Eve can use to determine her pay.
Hours 1 2 3 4 5
Pay 26 40 54 68 82
A. f(x) = x + 14
B. f(x) = 12x + 16
C. f(x) = 12x + 14
D. f(x) = 14x + 12
The linear function f Eve can use to determine her pay would be; D. f(x) = 14x + 12
What is a linear equation?A linear equation is an equation that has the variable of the highest power of 1. The standard form of a linear equation is the form Ax + B = 0.
Given that Eve earns $14 per hour for yard work and an extra amount for dog walking on Saturdays.
The table shows the data;
Hours 1 2 3 4 5
Pay 26 40 54 68 82
Thus, the linear function f Eve can use to determine her pay is;
f(x) = 14x + 12
To check;
f(x) = 14x + 12
f(x) = 14(1) + 12
f(x) = 14 + 12 = 26
Hence, The linear function f Eve can use to determine her pay would be; D. f(x) = 14x + 12
