A bag contains 4 white tiles and 8 black tiles. You select one tile at random from the bag. What is the probability that you select a black tile?
Answer:
p( black) = 2/3
Step-by-step explanation:

151 3/16 divided by 10 1/4
Answer: 59/4 or 14 3/4
Step-by-step explanation:
151 3 /16 ÷ 10 1 /4
2419 /16 ÷ 41 /4
2419/16 × 4/41
2419 × 4 /16 × 41
9676 /656
Divide both sides by 164
9676 ÷ 164 / 656 ÷ 164
59 /4 = 14 3 /4

3x−y=1?
Step-by-step explanation:
We wish to express 3x - y = 1
in slope-intercept form.
3x - y = 1
=> y = 3x - 1
Slope of line = 3, therefore
Slope of parallel line is also 3.
We have y = 3x + c.
When x = 1, y = 7.
=> (7) = 3(1) + c, c = 4
Hence the answer is y = 3x + 4.

Answer:cool
Step-by-step explanation:
what is the distance, in units, between the y-intercept of f(x) = x^2 +7x - 18 and the y-intercept of the linear function that passes through the points shown on the table below
x g(x)
-5 2
10 11
25 20
60 41
Answer:
13
Step-by-step explanation:
f(x) = x² +7x - 18
y interception: x=0 y = -18 (0 , -18)
line g(x): --- the data of (60,47) to make a linear function
y = mx + b
m = (11-2) / (10 - -5) = 9/15 = 0.6
b = mx - y = 0.6 * (-5) - 2 = - 5 ... y intercept: (0 , -5)
distance between 2 y intercept: 18-5 = 13
y = 0.6x - 5
Answer:
23
Step-by-step explanation:
f(x) (y intercept ) = -18
g(x) (y intercept) = 5
difference so f(x)-g(x)
-18-5 = -23
the answer cannot be negative

Find the value of X. Show your work.
Congruent triangle
Answer:
x = 3
Step-by-step explanation:
exterior angle of a triangle is equal to the sum of the measures of the two remote interior angles
97 + x = 64 + 27
x = 97 - 64 - 27 = 6
Answer: x=-6
you know that the interior angles of a triangle equal 180°. so lets find the remaining angle measure
64 + 27 = 91
180 - 91 = 89
so 89 is the third interior angle of the triangle. now let's find the exterior angle.
you know that the extended angle is supplementary; which means it will equal 180° as well. so lets add the third interior angle we just found and let's add it to the unknown expression:
89 + 97 + x = 180
186 + x = 180
-186 -186
x = -6
now it might seem wrong because x is negative and it feels like it should be positive. but let's check our answer.
64+27+89 does equal 180
and 97+(-6)+89 does equal 180
i hope this helps!

If the perimeter is 374 units, find the value of x and the area of the triangle.
The value of x is
The area is
square units.
Answer:
x = 17
Area = 10,362units²
Step-by-step explanation
Given the sides of the triangle
S1 = 9x+4
s2 = 8x-4
S3 = 4x+17
Perimeter of the triangle is the sum of all the sides
P = S1+S2+S3
374 = 9x+4+8x-4+4x+17
374 = 21x+17
21x = 374-17
21x = 357
x = 357/21
x = 17
Hence the value of x is 17
Area of the triangle is 1/2bh
A = 1/2bh
b is the base
h is the height
Let the base be 9x + 4 and height be 8x-4
b = 9x+4
b = 9(17)+4
b = 153+4
b = 157units
h = 8x-4
h =8(17)-4
h = 136-4
h = 132
Area = 1/2 * 157 * 132
Area = 157*66
Area = 10,362units²
A store receives customer satisfaction ratings that range between 0 and 100. In the first 13 ratings the store received, the average customer satisfaction rating was 75. What is the least value the store can receive for the 14th rating and still be able to have an average of at least 84 for the first 21 ratings?
Answer:
Step-by-step explanation:
From the given information:
For the first 10 ratings, the average value is 75.
For maintaining the average of 84 ratings for the first 21st rating, we have:
Total rating for 21 units = 84 * 21 = 1764
For 10 units = 84 *10 = 840
Now, the initial 10 unit average = 75 * 10 =750
The first 10 unit + last 10 unit = 840 + 750 = 1590
The difference = 1764 - 1590 =174 unit
So, in the 14th rating, he has to go with 174 units.

Movie tickets cost $6 for adults and $2 for children under the age of 12. If 175 movie tickets were sold with cash receipts of $750, how many children’s tickets were sold?
Answer:
75 child tickets and 100 adult tickets were sold.
Step-by-step explanation:
Given that adult tickets cost $ 6 and children's tickets cost $ 2, knowing that 175 tickets were sold for $ 750, to determine how many child tickets were sold the following calculation must be performed:
2 x 175 = 350
750 - 350 = 400
6 - 2 = 4
400/4 = 100
175 - 100 = 75
100 x 6 = 600
75 x 2 = 150
Therefore, 75 child tickets and 100 adult tickets were sold.
