Step-by-step explanation:
2/9n = -6
divide both sides by 2/9
n = -27
What is the theoretical probability of rolling a 3?
Answer:
1/6
Step-by-step explanation:
the number on the bottom of the fraction (denominator) is equal to the total number of possibilities (in this case there are 6 possibilities). for the number on top (the numerator) we are trying to work out the probability of rolling a 3. a 3 is only 1 of the 6 options (1, 2, 3, 4, 5, 6) so the number on top is 1.
I hope this was helpful :-)

An equilateral triangle has a perimeter of 12 x + 18 units. Which expression can be used to show the length of one side of the triangle?
6 (2 x + 3): Each side length is 2 x + 3 units.
3 (4 x + 6): Each side length is 4 x + 6 units.
2 (6 x + 9): Each side length is 6 x + 9 units.
x (12 + 18): Each side length is 12 + 18 units.
Answer:
3 (4 x + 6): Each side length is 4 x + 6 units.

Lauren is sewing a quilt using fabric squares.
The length of a side of a fabric square is represented by the expression x + 4.
Which expression represents the area of a fabric square?
4x + 6
2x + 8
x + 4
x2 + 8x + 16
Answer:
x^2 + 8x + 16
Step-by-step explanation:
Given length of square x + 4.
Area of square with side S is given by [tex]S^2[/tex].
Therefore are of square with side x + 4 is given by [tex](x + 4)^2[/tex]
Area of square = [tex](x + 4)^2\\=>(x + 4)*(x + 4)\\=> x(x + 4) + 4(x + 4)\\=> x^2 + 4x + 4x + 4*4\\=> x^2 + 8x + 16[/tex]
Thus, x2 + 8x + 16 expression represents the area of a fabric square.
A bag contains 1p, 2p and 5p coins
3/8 of the bag are 1p coins.
There are as many 5p coins than 1p coins in the bag.
There are 640 coins in total.
Work out the number of 2p coins in the bag.
Answer:
160 2p coins
Step-by-step explanation:
3/8 x 640 = 240 = 1p coins
240 = 5p coins
240 + 240 = 480
640 - 480 = 160

Find the area of the following parallelogram
Answer:
3.375 cm²
Step-by-step explanation:
The area (A) of a parallelogram is calculated as
A = bh ( b is the base and h the perpendicular height )
Here b = 2.25 and h = 1.5, thus
A = 2.25 × 1.5 = 3.375 cm²
Answer:
Step-by-step explanation:
A = base * height
= 2.25 * 1.5 = 3.38 cm^2 (ANS)

B
Answer:
B = 41.81
Step-by-step explanation:
sin B = opposite/ hyp
sin B = 2/3
Take the inverse sin of each side
sin ^-1 sin (B) =sin ^-1 (2/3)
B =41.8103149
To the nearest hundredth
B = 41.81
Park View Apartments has 2 buildings. Each building has 3 floors. Each floor has
16 windows. What is the total number of windows in the Park View Apartment
buildings?
What Is The Answer
Step-by-step explanation:
2 Buildings : 3 Floors Each : 16 Windows per Floor
Multiply 2 and 3 to get the total amount of floors.
2 times 3 equals 6
Then, multiply 6 and 16 to get the total amount of windows in the Park View Buildings.
6 times 16 equals 96
Therefore, there are 96 windows in total or 48 windows per building

Jan and Wayne went to the store to buy some groceries. Jan bought 2 cans of corn beef hash and 3 cans of creamed chipped beef for $4.95. Wayne bought 3 cans of corn beef hash and 2 cans of creamed chipped beef for $5.45.
Answer:
Corn Beef = x
Creamed Chipped beef = y
Jan:
2x + 3y = 4.95
Wayne:
3x +2y = 5.95
Graph two equation and find the point where two lines cross and that will be solution.
Point where two lines cross: (1.29, 0.79)
Corn Beef = $1.29
Creamed Chipped Beef = $0.79

Find the equation of the line shown.
HELP PLEASEEE
Answer:
y = x+6
Step-by-step explanation:
The y intercept is 6 ( where it crosses the y axis)
We need to find the slope
For each y unit it goes up, it goes to the right 1 x unit
m = 1/1 = 1
We can use the slope intercept form of the equation
y = mx+b where m is the slope and b is the y intercept
y = 1x+6
y = x+6

Cam rode her bike 5 times as far as Dante did. Dante rode 197 meters farther than Michael did. Cam rode 10.25 kilometers. How many meters did Michael ride? Complete the explanation of how you got your answer.
Answer:
1853metre
Step-by-step explanation:
Taking Danta distant as x
While Cam's will be 5x because he cover distance 5 time more than dante
I.e. Cam rode 10.25 km, to get what dante covers
5x=10.25
x=10.25/5
x=2.05km
Dante rode 2.05 km as calculated above
We must remember 1km=1000m. Hence, 2.05 km=2050 m
From the question, "Dante rod 197 m more than Michael", the distance Michael will ride then will be:
2050 metre - 197 metre
=1853 metre
Michael have rode 2863 metre
Four families are travelling. Order their speeds from least to greatest.
Sapons
80 km in 2 h
Silvers
180 km in 3 h
Johns
50 km in 1 h
Cunninghams
35 km in 30 min
(please help)
Step-by-step explanation:
We're going to convert all of these to km/h.
Sapons: 80km/2h => 40kmh
Silvers: 180km/3h => 60kmh
Johns: 50kmh
Cunninghams: (to get the 30 mins to 60 mins, multiply the top and the bottom by 2) 35km/30min => 70kmh
Now that they're all in the same form we can put them from least to greatest.
Answer:
(Least) - Sapons
- Johns
-Silvers
(Greatest) - Cunninghams

Answer:
[tex]\dfrac{108}{329}[/tex]
Step-by-step explanation:
From the table above
Total Number of commuters who used public transportation=329
Number of commuters who spent 60 or more minutes on public transportation=108
Therefore:
Given that a commuter used public transportation, the probability that the commuter had a commute of 60 or more minutes:
P ( 60 + minutes ∣ public transportation ) = [tex]\dfrac{108}{329}[/tex]
