.
5 red
4 yellow
3 black
2 white
Nico will randomly choose one marble. What is
the probability that he will choose a white
marble?
B.
c.
Answer:
2/14
Step-by-step explanation:
See there is a total of 14 marbles overall. the question is asking what is the chance that you will pick a white marble out of the 14 marbles in total. Therefore you only have a 2/14 or 1/7 of a chance that you will pick that white marble.

Answer:
a) x = -2+√3 and -2-√3
b) x = -1 + 2√3/3 and -1 - 2√3/3
c) x = 3.185 and 0.315
Step-by-step explanation:
To solve the following quadratic equation, we will use the general formula
x = -b±√b²-4ac/2a
a) x²+4x+1 = 0
a = 1, b = 4 and c = 1
Substitute into the formula
x = -4±√4²-4(1)(1)/2(1)
x = -4±√16-4/2
x = -4±√12/2
x = -4±2√3/2
x = (-4+2√3)/2 and (-4-2√3)/2
x = -2+√3 and -2-√3
b) 3x²+6x-1 = 0
a = 3, b = 6 and c = -1
Substitute into the formula
x = -6±√6²-4(3)(-1)/2(3)
x = -6±√36+12/6
x = -6±√48/6
x = -6±4√3/6
x = (-6+4√3)/6 and (-6-4√3)/6
x = -1 + 2√3/3 and -1 - 2√3/3
c) 2x² - 7x + 2 = 0
a = 2, b = -7 and c = 2
x = -(-7)±√(-7)²-4(2)(2)/2(2)
x = 7±√49-16/4
x =7±√33/4
x = 7±5.74/4
x = 7+5.74/4 and 7-5.74/4
x = 12.74/4 and 1.26/4
x = 3.185 and 0.315

Washington High School has a total of 625 students. There are 250 girls in the school. What is the ratio of girls to boys at Washington High School?
A) 2:3
B) 2:5
C) 3.1
D) 3.2
Answer:
B)
Step-by-step explanation:
625:250=2.5
so i think it is B
Answer:
A 2:3
Step-by-step explanation:
625-250= 375 which is the number of boys in the school now it's 375 and 250
250:375
= 250/375
Dividing by 5/5, we have,
50/75
Again, Dividing by 5/5, we have,
10/15
Again, Dividing by 5, we have,
2/3
Hence, the ratio 250:375 in the simplest form will be 2:3

Ms. Fry started walking as her New Year's resolution. She calculated that she can walk ½ mile in ¼ of an hour. What is her walking rate in miles per hour?
Answer:
the walking rate miles per hour is 2 miles per hour
Step-by-step explanation:
The computation of the walking rate miles per hour is shown below;
Given that
She can walk half mile in one-fourth of an hour
= Miles ÷ hours
= (1÷ 2) ÷ (1 ÷4)
= 0.50 ÷ 0.25
= 2 miles per hour
Hence, the walking rate miles per hour is 2 miles per hour

Use intercepts to graph the linear equation -2x+7y=-21 Question 2
Identify the points corresponding to the intercepts
Answer:
The point representing the y-intercept is: (0, -3)
The black dot represents the y-intercept on the attached graph. It is very clear at y = 0, x = -3.
The point representing the x-intercept is: (10.5, 0)
The red dot represents the x-intercept on the attached graph. It is very clear at x = 0, y = 10.5
Step-by-step explanation:
Given the linear equation
-2x+7y=-21
Determining the y-intercept
We know that the value of y-intercept can be determined by setting x = 0, and determining the corresponding value of y.
substituting x = 0 in the equation
-2x+7y=-21
-2(0) + 7y = -21
0+7y = -21
7y = -21
divide both sides by 7
7y/7 = -21/7
y = -3
Therefore, the point representing the y-intercept is: (0, -3)
The black dot represents the y-intercept on the attached graph. It is very clear at y = 0, x = -3.
Determining the x-intercept
We know that the value of x-intercept can be determined by setting y = 0, and determining the corresponding value of x.
substituting y = 0 in the equation
-2x+7y=-21
-2x+7(0) = -21
-2x + 0 = -21
-2x = -21
divide both sides by -2
-2x / -2 = -21 / -2
x = 21/2
x = 10.5
Therefore, the point representing the x-intercept is: (10.5, 0)
The graph of the linear equation containing the y-intercept (0, -3) and x-intercept (10.5, 0) is shown and attached below.
The red dot represents the x-intercept on the attached graph. It is very clear at x = 0, y = 10.5
Please check the attached graph.

Minha says triangle A with angles measuring 34 ° and 57 ° is similar to triangle B with angles measuring 57 ° and 89 ° . What Minha said is correct, but why is she correct?
A. Minha is correct because each triangle has an angle measuring 57 °
B. Minha is correct because 180 - (34 + 57) = 89
which means two angles in triangle A are congruent to two angles in triangle B
Answer:
b
Step-by-step explanation:
Answer: D./Yes, because 180
- (34 + 57) = 89 which means two angles in triangle A are congruent to two angles in triangle B

In the trapezoid below, x = [ ? ].
2x+6
I
5x=20
4r+2
Answer:
x = 12
Step-by-step explanation:
To get the value of x, we use the mid-segment theorem of trapezoid
The theorem is that the mid-segment is half the sum of the other two segments
We have this as
;
5x - 20 = 1/2(2x + 6 + 4x + 2)
2(5x-20) = 6x + 8
5x -20 = 3x + 4
5x -3x = 4 + 20
2x = 24
x = 24/2
x = 12

Answer:
16. a: (-90°, (4, 3)); b: (90°, (0, 3)); c: (-90°, (0, 0))
17. a: (down, (4, -1)); b: (right, (4, 3)); c: (up, (5, 2))
Step-by-step explanation:
We don't know what notation you're used to seeing for rotations. Here. we'll use the form [degrees CCW, (center)]. (CW angles are negative.) In any rotation, the center is the point that is invariant (remains in the same place)
16.
a) The tail is invariant, so the rotation is (-90°, (4, 3)).
b) The tip is invariant, so the rotation is (90°, (0, 3)).
c) The origin is invariant, so the rotation is (-90°, (0, 0))
__
17.
a) The tail is invariant, so the arrow is pointing down with the tip at (4, -1).
b) The center is invariant, so the arrow is reversed. It is pointing right with the tip at (4, 3).
c) Point (2, 3) is invariant, so the arrow is pointing up with the center at (5, 0). The tip is at (5, 2).
_____
Additional comment
If you have trouble visualizing these rotations, you might find it useful to trace the arrow on a piece of (semi-)transparent medium (plastic or tracing paper) so that you can move it as required to match the descriptions in the problem statement. A pin, or a dot on your tracing, can serve to fix the center of rotation. A little hands-on never hurts in math and geometry.
line v has a slope of - 5/2. line w has a slope of - 2/5. are line v and line q parallell, perpendicular, or neither?
Answer:
neither
Step-by-step explanation:
Parallel lines need to have the same slope.
Perpendicular lines have opposite reciprocal slopes.
-5/2 and -2/5 are opposite reciprocals nor are they equal.
What is the equation of the following are you sure to scroll down first to see all answer options
Answer:
Y=-3x+0 or Y=-3x
Step-by-step explanation:
Y=mx+b
m=slope
b=y-intercept (where the line crosses the y axis)
The line crosses the Y axis at (0,0), so:
Y=mx+0 or
Y=mx
Slope:
Rise/run= Change in y/Change is x= 9/-3=-3
So:
Y=-3x+0 or
Y=-3x
Answer: 3x + y = 0
Step-by-step explanation: Remember that slope is represented by
rise over run from one point to the next on our graph.
To get from the point (0, 0) to (3, -9), we go down -9 units
so our rise is -9 and we run 3 units so our run is 3.
Our slope therefore or m = -9/3 or -3.
Our y-intercept is represented by the point where this line
crosses the y-axis which in this case is up 0 units.
So our y-intercept or b = 0.
Since we have the slope and y-intercept of our line,
we can now write its equation in y = mx + b form.
Since m = -3 and b = 0, that gives us y =-3x + 0.
Now we convert this equation to standard form.
Just add 3x to both sides to get 3x + y = 0.
So the equation of this lie is 3x + y = 0.

find the measure of the missing angle
Step-by-step explanation:
given
as it is right angled triangle so
Let the unknown angle be x Then
90° + 40° + x = 180° ( being sum of angles of triangle)
130° + x = 180°
x = 180° - 130°
Therefore x = 50°
Hope it will help you :)❤
Answer:
The other angle will be 50°.
Step-by-step explanation:
Given that the diagram shows a right angle triangle (90°) and the total sum of angles of a triangle is 180°. In order to find the other angle, you have to subtract :
x + 40° + 90° = 180°
x + 130° = 180°
x = 180° - 130°
x = 50°
