The number line is a graph of the Integers
Answer:
the one complete circuit of the track is 600 meters
Step-by-step explanation:
divide the 2.4 kilometers by 4 which gives you your answer.
2.4 kilometers = 2,400 meters
2,400/4 = 600
Answer:
Step-by-step explanation:
Given
Geometric Sequence (GP)
Required
Determine T₁₂
The nth term of a GP is calculated as thus;
In this case;
; and 
Substitute these values in the above formula
Open the bracket
<em>Hence, the 12th term of the sequence is </em>
Answer:△DEF is congruent to △D′E′F′ because the rules represent a translation followed by a reflection, which is a sequence of rigid motions.
Step-by-step explanation:
A rigid motion of the plane is a motion which maintain distance.
Translation is a kind of rigid motion used in geometry to trace a function that moves an object a particular distance.
A reflection is also a kind of rigid motion . It is mainly a 'toss' of a shape across the line of reflection.
So,△DEF is mapped to △D′E′F′ using the rule (x,y)→(x,y+1) ( which is a translation.) followed by (x,y)→(x,−y)(which is reflection),therefore it is a sequence of rigid motions.
Let x = questions with 2 points and y = questions with 4 points;
We solve the equation: x + y = 40 and 2x + 4y = 100;
Then, x = 40 - y;
2( 40 - y ) + 4y = 100;
80 - 2y + 4y = 100;
80 + 2y = 100;
2y = 20;
y = 10;
x = 40 - 10;
x = 30;
