A large jar contains 500 marbles. All of the marbles in the jar are either blue or yellow, and there are 3 times as many blue marbles as yellow marbles. Which equation can be solved to find the number of yellow marbles in the jar?
Answer:
The equation to solve to find the number of yellow marbles =
3y + y = 500
4y = 500
The number of yellow marbles = 125
Step-by-step explanation:
Let the number of
Blue marbles = x
Yellow marbles = y
A large jar contains 500 marbles.
x + y = 500
All of the marbles in the jar are either blue or yellow, and there are 3 times as many blue marbles as yellow marbles.
3y = x
Hence, we substitute 3y for ymx in the above equation
3y + y = 500
4y = 500
y = 500/4
y = 125
The number of yellow marbles = 125

solve graphically this linear system of equations[tex]\left \{ {{x=3} \atop {y+1=0}} \right.[/tex]
Answer:
(3,-1)
Step-by-step explanation:
The given equations are :
x = 3 ..(1)
y+1 = 0 ....(2)
We need to solve the equations graphically. x = 3 means draw a line parallel to y axis.
For y+1=0
y = -1
Draw a line parallel to the negative x axis. The attached figure shows the graph for the given equations. The solution is (3,-1).

In △PQS, m∠Q=22°, m∠S=65°, and s=176. Identify q rounded to the nearest tenth.
Using the law of sines, the value of q is: D. 72.7.
What is the Law of Sines?The law of sines is given as: sin A/a = sin B/b = sin C/c.
Thus, given △PQS, where:
m∠Q = 22°
m∠S = 65°
s = 176
Applying the law of sines, we have:
sin Q/q = sin S/s
Substitute
sin 22/q = sin 65/176
q = (sin 22 × 176)/sin 65
q = 72.7
Therefore, using the law of sines, the value of q is: D. 72.7.

1 3/4 cups of flour for one batch but he wants to make 1 1/2 batches. How many more cups of flour will he need
Answer:
[tex]2\frac{5}{8} cups = 1\frac{1}{2}\ batches[/tex]
Step-by-step explanation:
Given
[tex]1\frac{3}{4} cups = 1\ batch[/tex]
Required
Number of cups for [tex]1\frac{1}{2}[/tex] batches
[tex]1\frac{3}{4} cups = 1\ batch[/tex]
Multiply both sides by [tex]1\frac{1}{2}[/tex]
[tex]1\frac{1}{2} * 1\frac{3}{4} cups = 1\ batch * 1\frac{1}{2}[/tex]
[tex]1\frac{1}{2} * 1\frac{3}{4} cups = 1\frac{1}{2}\ batches[/tex]

Describe the sequence of transformations that maps PQR into P'Q'R' use the drop-down menus to explain your answer
Answer:
Rotation of 180° clockwise around the origin
Step-by-step explanation: if you rotate the first triangle 90 degrees, it will be in the lower quarter, so you need to rotate it 1 more time.
The transformations are clockwise rotation 180° and translation down by 1 unit.
What is rotation?Rotations are transformations that turn a shape around a fixed point. To rotate a shape we need: a centre of rotation. an angle of rotation (given in degrees) a direction of rotation – either clockwise or anti-clockwise.
From the given graph, the coordinates of triangle PQR are P(2, 1), Q(4, 6) and R(4, 1).
Rotating a point that has the coordinates (x,y) 180° about the origin in a clockwise direction, we have (-x,-y).
Here,
P(2, 1) → P'(-2, -1)
Q(4, 6) → Q'(-4, -6)
R(4, 1) → R'(-4, -1)
The translation down by 1 unit, we get (x, y-k)
P'(-2, -1) → P'(-2, -2)
Q'(-4, -6) → Q'(-4, -7)
R'(-4, -1) → R'(-4, -2)
The coordinates of triangle P'Q'R' are P'(-2, -2), Q(-4, -7) and R'(-4, -2)
Therefore, the transformations are clockwise rotation 180° and translation down by 1 unit.

if a trail runner zig-zags 15m to the west and then 15m to the east:
what is the runner's total distance?
what is the runner's total displacement?
Answer:
Total distance = 30m
Total displacement = 0m
Step-by-step explanation:
a) Distance is a scalar quantity that does not specify direction
Hence if a trail runner zig-zags 15m to the west and then 15m to the east, the total distance will be the sum of the distance travelled both to the west and east.
total distance = distance through west + distance through east
total distance = 15m + 15m
total distance = 30m
Hence the runner's total distance is 30m
b) Displacement is a vector quantity and it specifies direction. Hence we will take into consideration the direction taken
Since East direction is positive, the displacement through east is +15m
Since West direction is negative, the displacement through west is -15m
Total displacement = +15 - 15
Total displacement = 0m
Hence the runner's total displacement is 0m
