Answer:
Step-by-step explanation:
t is the number of hours
12.24+0.11t = 12.74-0.15t
0.11t + 0.15t = 12.74 - 12.24
0.26t = 0.5
t= 0.5/0.26
t= 1.92 hours
approx to 2 hours
The descriptions below outline different options for adding cards to your baseball card
collection. Use x to represent the number of months and y to represent the total number
of cards you have
For each equation and graph, drag the situation that can be modeled by that
relationship into the space in that row.
CLI
You start with 1 card, and the number of cards triples each month.
You collect 3 cards each month.
The total cards equals the number of months multiplied by itself and then tripled.

From a point T ,a man moves 12km due west and then moves 12km due south to another point Q. Calculate the bearing of T from Q
How to find the bearing between two points?
Let's assume that:
The point T is the point (0km, 0km).East is the positive x-axisNorth is the positive y-axis.Then, if the man moves 12 km due west and then 12 km due south, the new position is:
( 0km - 12km, 0km - 12km) = (-12 km, -12km)
This lies just in the middle of the third quadrant, so we have 90° per quadrant plus half of that:
90° + 90° + 45° = 225°
This is the angle measured from the positive x-axis, which is the east.
If we consider the negative x-axis, which is the west, the angle would be:
θ = 45°
This means that the bearing is 45° south of west.

What is the value of f?
Answer: f=78
Step-by-step explanation:
En un cuadrilatero la suma de los angulos internos es 180°
Ademas los angulos alternos internos so iguales.
Por lo tanto el angulo frente a 72° en diagonal tambien es 72°
Si sumamos esos dos angulos obrenemos 144°Si restamos este resultado de 360° obtenemos 360°-144=216 °
Finalmente debemos dividir entre dos los 216°
216/2 = 78°

so initially the paper is in full piece.
it is cut into half, which makes into 2. this is pattern 1.
then the halves is further divided in to 2.
then the total becomes 4. then the four pieces are cut into halves, which makes the total of 8 pieces, that is pattern 3..
is if we see the pattern it is a geometric progression.

[tex]6(x-1)-x=-21[/tex]
[tex]\tt Thanks! :)[/tex]
Step-by-step explanation:
Given that:
6(x - 1) - x = -21
Multiply the number outside of the brackets with numbers in the brackets on LHS.
⇛6x - 6 - x = -21
Shift constant from LHS to RHS, changing it's sign.
⇛6x - x = -21 + 6
Subtract the values on LHS and RHS.
⇛5x = -15
Shift the number 5 from LHS to RHS.
⇛x = -15/5
Therefore x = -3

3x - 3 = 15
Find The Value Of x ~
[tex] \: \: \: [/tex]
Answer:
x = 6
Explanation:
3x - 3 = 15
3x = 15 + 3
3x = 18
x = 18 ÷ 3
x = 6
The value of x from the expression is 6
Expression and equationGiven the equation
3x - 3 = 15
Add 3 to both sides
3x - 3 + 3 = 15 + 3
3x = 18
Simplify the result
3x = 18
Divide both sides by 3
3x/3 = 18/3
x = 6
Hence the value of x from the expression is 6

Answer:
if both expressions have the same value after submitting and simplifying for x = 6 and x = 2, then they are equivalent. Substitute 6 for each variable, 6 for each variable, x, in both expressions. The value on both expressions is 15. Now, substitute 2 for each variable, x, in both expressions. The value of both expressions is 7. Therefore, the expressions are equivalent.

Answer:
Distance traveled is equal to the length of wheel circumference as it “unrolls” along the ground as the wheel turns. One full turn of the wheel will move the robot one circumference's distance. Therefore, students will find the distance traveled by multiplying circumference by the number of rotations.
