You are playing a board game with your little sister. Moves are determined by rolling 2 six-sided dice. The red die tells you the direction of your move, and has 4 faces
that say "forward and 2 faces that say backward." The green die tells you how far to move, and has 1. 1. 2.2.3, and 4 on the faces. On your turn, what is the
probability that you move backward 2 spaces
Answer: The probability is 1/9.
Step-by-step explanation:
First, let's define the possible outcomes of each dice:
Red: Forward (4 times), Backward (2 times)
Green : {1, 1, 2, 2, 3, 4}
We want to find the probability of moving backward 2 spaces.
Then we need to find the probability of rolling a "backward" in the red dice, and a 2 in the green dice.
First, the probability of rolling a backward in the red dice is equal to the quotient between the number of outcomes that are "backward", and the total number of outcomes in the dice (there are 2 backwards and 6 outcomes in total), this is:
p1 = 2/6 = 1/3.
And the probability of rolling a 2 in the green dice is equal to the quotient between the number of outcomes with a 2, and the total number of outcomes. (The 2 appears two times, and there are 6 possible outcomes):
p2 = 2/6 = 1/3.
Now, the probability of both events happening at the same time is equal to the product of the individual probabilities, then the probability of moving backwards 2 spaces is:
P = p1*p2 = (1/3)*(1/3) = 1/9.

On Wednesday Mr. Miles walked in right at 9/10 of the trail then he walked one eights of the trail back and you stop to rest what fraction of the course with Mr. Miles from the beginning of the trail when he stopped
Answer:
31/40
Step-by-step explanation:
Given that:
Fraction of the trail walked intulally = 9/10
Fraction of the trail walked back = 1/8 before stopping to rest
His current distance from the beginning :
Distance walked initially - distance walked back
9/10 - 1/8
The L. C. M of 10 and 8 = 80
Hence,
9/10 - 1/8
= (72 - 10) / 80
= 62 / 80
= 31 / 40
Hence, his rest point or position is 31/40 from the beginning of the trail
The graph shows the relationship between the number of gallons of gas that are purchased and the total cost
Answer:
962.5 is the answer
Step-by-step explanation:
One gallon cost 2.5 dollars and according to this 1*2.5=2.5+2*5=10........
The relationship between no. of gallons and the total cost of purchasing is in a linear relationship.
What is a linear relationship ?A linear relationship between two variable is when one variable is increased or decreased by some constant this results in same amount of increase or decrease in the another variable.
According to the given data
The relationship between the number of gallons of gas that are purchased and the total cost is in linear relationship.
A linear relationship forms when increasing a variable k times results in increase of k times on the another variable and same is for decrease.
We can observe when x = 1, y = 2.5.
Now suppose k is 10
∴ x = 1k and y = 2.5k
x = 10 and y = 25. Which is already given in the diagram showing a linear relationship.

Ben has a collection of baseball cards. He has a total of 1,600 cards. Of the baseball cards, 35% are dated before 1980, 25% are dated from 1980 to 2000, and
the rest are dated after 2000.
How many baseball cards in Ben's collection are dated after 2000?
Answer:
640 cards
Step-by-step explanation:
If the rest are dated after 2000, that means that 40% are dated after 2000, since 25% + 35% = 60%
To find how many are dated after 2000, multiply 1,600 by 0.4:
1,600(0.6) = 640
So, 640 of the baseball cards are dated after 2000

Answer:a
Step-by-step explanation:
In December of 2003, the average price for a gallon of regular gas in the United States was $1.50.
b. Is the relationship between number of gallons and cost proportional? Explain.
Answer:
yes
Step-by-step explanation:
because the cost stays the same and you would multiply blank gallons of gas by 1.50 every time so it is proportional. For example: it would be $1.50 to 1 gallon, $3 to 2 gallons, $4.50 to 3 gallons and would keep going like that, adding the same amount every time
Molly is making a quilt for her mother. The quilt will have several designs. One of the designs is shown below. What is the total perimeter of this design, in inches? A. B. C. D.
Answer: A. 12 + 12√12
Step-by-step explanation:
The perimeter of a triangle is acquired by adding up all the sides of the triangle.
In this case therefore the perimeter is;
= 2√2 + 2√2 + 4
= 4√4 + 4
There are 3 triangles so the total perimeter is;
= 3 * (4√4 + 4)
= 12√12 + 12
= 12 + 12√12

A scuba diver dove from the surface of the ocean to an elevation of -59 9/10 feet at a rate of -18.4 feet per minute. After spending 12 minutes at that elevation, the diver ascended to an elevation of -18 9/10 feet. The total time for the dive so far was 19 1/8 minutes. What was the rate of change in the diver's elevation during the ascent? Round your answer to the nearest hundredth.
The rate of change of the diver's elevation was _______ ft/min.
Please include all of the work required to complete the mathematical problem. I would really appreciate it! <3
Answer:
The rate of change of the diver's elevation was 10 53/89 ft./min
Step-by-step explanation:
The given parameters are;
The initial elevation of the diver = 0 feet (Ocean surface level)
The depth to which the diver dove = -59 9/10 feet
The rate at which the diver descended = -18.4 feet/minute
The duration the diver spends at the elevation, t₁ = 12 minutes
The depth to which the diver ascended to = -18 9/10 feet
The total time the diver takes so far in the ocean, [tex]t_{(tot)}[/tex] = 19 1/8 minutes
Therefore, we have;
The time it takes the diver to descend to -59 9/10 feet t₂ = -59 9/10/(-18.4) = 3 47/184 minutes
The duration of the divers ascent = [tex]t_{(tot)}[/tex] - t₁ - t₂ = 19 1/8 - 12 - 3 47/184 = 3 20/23 minutes
The rate of change of the divers elevation in ascent = Distance of elevation/Time
The rate of elevation of the divers elevation in ascent = (-18 9/10 - (-59 9/10))/(3 20/23) = 41/(3 20/23) = 943/89 feet/minute = 10 53/89 feet/minute
The rate of change of the diver's elevation = 10 53/89 ft./min ≈ 10.6 ft./min.

The equation of the line is y - 3 = 2.5(x - 2) ⇒ D
Step-by-step explanation:
The rule of the slope of a line is m = [tex]\frac{y2-y1}{x2-x1}[/tex] , where
(x1, y1) and (x2, y2) are two points on the lineThe point-slope form of a line is y - y1 = m(x - x1), where
(x1, y1) is a point on the lineFrom the given figure
∵ The line passes through points (2, 3) and (0, -2)
∴ x1 = 2 and y1 = 3
∴ x2 = 0 and y2 = -2
→ Substitute them in the rule of the slope to find it
∵ m = [tex]\frac{-2-3}{0-2}=\frac{-5}{-2}=2.5[/tex]
∴ m = 2.5
→ Substitute the values of m, x1, y1 in the form of the equation above
∵ m = 2.5, x1 = 2, y1 = 3
∵ y - 3 = 2.5(x - 2)
∴ The equation of the line is y - 3 = 2.5(x - 2)

Absolute value equations are equations where the variable is within an absolute value operator, like |x-5|=9. The challenge is that the absolute value of a number depends on the number's sign: if it's positive, it's equal to the number: |9|=9. If the number is negative, then the absolute value is its opposite: |-9|=9.

O Perímetro de triângulo isósceles mede 24cm. Qual é a medida de comprimento dos lados congruentes sabendo-se que o lado não congruente mede 7cm de comprimento?
Answer:
La longitud de los lados congruentes =
B = 8.5cm
C = 8.5 cm
Step-by-step explanation:
El perímetro del triángulo isósceles mide 24 cm.
El lado no congruente mide 7 cm de largo.
Lados congruentes significa lados que son iguales o iguales entre sí.
El perímetro de un triángulo es =
Lado A + Lado B + Lado C
Por lo tanto,
24 = 7 cm + B + C
24 - 7 = B + C
17 cm = B + C
Los dos lados son congruentes,
B = C
Por lo tanto, 17 cm / 2
= 8.5 cm
La longitud de los lados congruentes =
B = 8.5 cm
C = 8.5 cm
