You have to solve this to get your answer. This is a case where you have to use the pythagorean theorem.
Answer:
this is a right angle triangle.
which means that we can use hypotenuse theorem to solve it.
the hypotenuse theorem:-
a^2 +b^2 =c^2
where a and b are the sides opposite to the hypotenuse.
[(the longest side) the longest side of the triangle is always opposite to the right angle]
so...
a = 24
b = 7
a^2 + b^2 = c^2
24^2 + 7^2 = c^2
576 + 49 = c^2
625 = c^2
don't stop here, you could lose marks. I have seen my classmates do this silly and small mistake and lose 1/2 a mark.
√625 = c
25 = c
thus the length of the third side is 25.

Adam takes a bus from school to his house. If Adam lives 20 km from
school and it takes him 10 minutes to get there, what was the average
velocity of the trip?
1.0 km/min
1.5 km/min
O2.0 km/min
O 2.5 km/min
Answer:
2.0 km/min
Step-by-step explanation:
20/2=10
Hope this helps!!!
Answer:
2.0 km/min
Step-by-step explanation:
To find the average velocity, divide the number of km by the number of minutes:
20/10
= 2
So, the average velocity of the trip was 2.0 km/min

What is the initial value in this question y=8x+6 8 or 6?
Answer:
it should be an 8
Step-by-step explanation:
The initial value in this question y = 8x+6 will be 8 .
What is a system of equations?A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.
The equation is given as;
y = 8x+6
We can see that the equation contains two terms that are 8x and 6.
The initial value is the first number of the first term in the equation.
Here, the first term is 8x.
Hence, the initial value in this question y = 8x+6 will be 8 .

The solution to the given system of equations will be (0, -1). which is the correct option (B).
What is the Linear equation?A linear equation is defined as an equation in which the highest power of the variable is always one.
The system of linear equations y = 2 x minus 1 and y = negative 4 x minus 1 which is given in the question.
y = 2x - 1 ....(i)
y = -4x - 1 ....(ii)
Substitute the value of equation (i) in equation (ii) and solve for variable x :
2x - 1 = -4x - 1
Rearrange the terms of variable "x" and combine them,
2x + 4x = -1 + 1
6x = 0
x = 0
Substitute the value of x = 0 in equation (ii) and solve for variable y :
y = -4(0) - 1
y = -1
Therefore, the solution to the given system of equations will be (0, -1).

A model car is built to a scale of 1 in. : 2.5 ft. If the model is 5.8 in. Long how long is the car in real life?
Answer:
14.5 ft
Step-by-step explanation:
We are told that the model car is built to a scale of 1 in. : 2.5 ft.
That means 1 inches represents 2.5 ft in actual measurement.
Thus, for a 5.8 inch long model, the real life measurement is;
(5.8 inch × 2.5 ft)/1 inch = 14.5 ft

Given:
[tex]\Delta ABC\sim \Delta QRS[/tex]
To find:
The missing value of m.
Solution:
We have,
[tex]\Delta ABC\sim \Delta QRS[/tex]
Corresponding parts of similar triangles are proportional.
[tex]\dfrac{AB}{QR}=\dfrac{AC}{QS}[/tex]
Putting the given values, we get
[tex]\dfrac{m}{10}=\dfrac{2}{4}[/tex]
[tex]\dfrac{m}{10}=\dfrac{1}{2}[/tex]
Multiply both sides by 10.
[tex]\dfrac{m}{10}\times 10=\dfrac{1}{2}\times 10[/tex]

Julie works at a pizza place in Phoenix. She receives a 15% discount on any pizza that she buys. If a large pizza costs $14.00, what is the amount of Julie’s discount? What is the final cost of her pizza?
Answer:
The final cost of her pizza is $11.90
Step-by-step explanation:
First we need to convert 15% into a decimal, which is 0.15.
Now we multiply $14 and 0.15.
$14 × 0.15 = $2.10.
Now we subtract $2.10 from $14.00.
$14.00 - $2.10 = $11.90
