Q - A vehicle with an empty fuel tank has a mass of 1050kg. One litre of petrol has a mass of 737g. What is the minimum amount of whole litres of petrol that would cause the total mass to exceed 1100kg?
Please help me.
Answer:
The minimum balance is 68 liters
Step-by-step explanation:
Let the number of liters of petrol required be x
Given that One litre of petrol has a mass of 737g, x liters will have a mass
= 0.737x kg
Recall that 1 kg = 1000g
Since the empty fuel tank has a mass of 1050kg
The total mass = 1050 + 0.737x IN kg
For the total mass to exceed 1100kg, then
1050 + 0.737x > 1100
0.737x > 1100 - 1050
0.737x > 50
Divide both sides by 0.737
x > 50/0.737
x > 67.84260516

Answer:
13.21148134 meters
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
cos theta = adj/ hyp
cos 39 = x /17
17 cos 39 = x
13.21148134 = x
Answer:
Step-by-step explanation:
take 39 degree as reference angle
using cos rule
cos 39=adjacent/hypotenuse
0.77=x/17
0.77*17=x
13.09=x

In a class of students, the following data table summarizes how many students have a
brother or a sister. What is the probability that a student chosen randomly from the
class does not have a sister?
Has a brother Does not have a brother
Has a sister
3
12
Does not have a sister
2.
Answer:
Step-by-step explanation:
total students = 27
students do not have a brother probability = 13/27
students do not have a sister probability = 12/27
= 4/9
Hope this is correct :)
The probability that a student is chosen randomly from the class does not have a sister is 0.375.
The probability that a student is chosen randomly from the class Has a brother is 0.208.
The probability that a student is chosen randomly from the class does not have a brother is 0.7916.
The probability that a student is chosen randomly from the class Has a sister is 0.625.
What is the probability?Probability is the branch of mathematics, which discusses the occurrence of a random experiment.
First, we need to calculate how many total students there are.
Once we have the total we have to divide the number in the category that we want by the total number of students to calculate the probability of randomly getting a student in that category.
Total Students = 3 + 12 + 2 + 7 = 24 students
The probability that a student is chosen randomly from the class does not have a sister is;
[tex]= \dfrac{2+7}{24}\\\\=\dfrac{9}{24}\\\\=0.375[/tex]
The probability that a student is chosen randomly from the class Has a brother is;
[tex]= \dfrac{3+2}{24}\\\\=\dfrac{5}{24}\\\\= 0.208[/tex]
The probability that a student is chosen randomly from the class does not have a brother is;
[tex]= \dfrac{7+12}{24}\\\\=\dfrac{19}{24}\\\\= 0.7916[/tex]
The probability that a student is chosen randomly from the class Has a sister is;

Answer:
46 ≥ 2m + 4
m ≥ 21
Step-by-step explanation:
At least is ≥
Karen's age = 46 years old
Mary's age = m years old
Karen is at least 4 years more than twice mary's age (m).
46 ≥ 2m + 4
46 - 4 ≥ 2m

As apart of her physical fitness training, Kaylee cycled at 30km/h and then jogged at 8 km/h. She spent 2 hours working out and covered a distance of 49 km. How long did Kaylee spend at each activity?
Answer:
for cycling, time is 1.5 hours
for hogging time is 0.5 hour.
Step-by-step explanation:
speed of cycling = 30 km/h
speed of jogging = 8 km/h
total time = 2 hrs
total distance, D = 49 km
Let the time for cycling is t, so that time time for jogging is 2 - t .
distance = speed x time
49 = 30 x t + 8 (2 - t)
49 = 30 t + 16 - 8 t
33 = 22 t
t = 1.5 hour
So, time for cycling is 1.5 hours and time for jogging s 0.5 hr.
Solve the equation
1 . J + -2 = -22
J + -2 = -22
Adding a negative number changes the equation to subtract ruin:
J - 2 = -22
Now add 2 to both sides to get the answer:
J = -20
Collect like term
J= -22 - 2
J= - 20
These two lines represent a system of equations.

Vertex of a quadratic function:
Suppose we have a quadratic function in the following format:
[tex]f(x) = ax^{2} + bx + c[/tex]
It's vertex is the point [tex](x_{v}, y_{v})[/tex]
In which
[tex]x_{v} = -\frac{b}{2a}[/tex]
[tex]y_{v} = -\frac{\Delta}{4a}[/tex]
Where
[tex]\Delta = b^2-4ac[/tex]
If a<0, the vertex is a maximum point, that is, the maximum value happens at [tex]x_{v}[/tex], and it's value is [tex]y_{v}[/tex].
y = -2x2 + 8x + 5
Quadratic function with [tex]a = -2, b = 8, c = 5[/tex]
What is the maximum height that the stone reaches?
y value of the vertex. So
[tex]\Delta = 8^2-4(-2)(5) = 64 + 40 = 104[/tex]
[tex]y_{v} = -\frac{104}{4(-2)} = 26[/tex]
The maximum height that the stone reaches is of 26 feet.

Johnny wants to buy a lottery ticket, so he decides on the ones that give him a 1 in 3 chance of winning! If Johnny buys 15 lottery tickets, how many times would you expect him to win?
Answer:
5 or less chances.
Step-by-step explanation:
well because if he buys 15, 1 in 3 chance tickets, the highest amount of times he would win would be 5 because 15 is the chances of winning multiplied by the tickets he could win.

Step-by-step explanation:
(f-g)(x) simply means to subtract both expressions. really literally.
and we go through it power by power of x.
the highest power/exponent of x is 3 (x³). only f(x) has one.
so, -7x³ is the first part of f-g.
next is x².
11x² - 6x² = 5x², which is the second part of f-g.
next is x.
-8x - (-14x) = -8x + 14x = 6x, which is the third part of f-g.
next is x⁰ (in other words, no x, just a constant).
4 - (-3) = 4 + 3 = 7, which is the 4th part of f-g.
we have no x to the power of -1 or -2, so we have -3
0 - (-4x‐³) = 4x‐³, which is the last part of f-g.
so, it is clearly the first answer option.

In the circle below, EG is a diameter and EF is tangent at E. Suppose mEF = 124°. Find the following. Does anyone know this?
Answer:
Step-by-step explanation:
If EG is a diameter, then arc EFG is a semicircle and its measure is 180. Arc FG then is 180 - 124 = 56. Since angle FEG is an inscribed angle and the arc it cuts off is arc FG, then the measure of the inscribed angle is half the measure of the arc it cuts off...so angle FEG is 28 degrees. Keep that in mind; we'll need it in a sec.
If HE is tangent to the circle at E, then angle HEG is a 90 degree angle. Adding that to angle FEG will give you angle FEH. Angle FEH = 90 + 28 = 118
