Answer:
9
Step-by-step explanation:
60/(v+3）=30/(v-3)
2(v-3)=v+3
2v-6=v+3
v=9
Speed is the ratio of distance and time.
It shows how fast an object is moving at a given time.
Speed = Distance / Time
The rate of the rowing team in still water is 9 miles per hour.
What is speed?Speed is the ratio of distance and time.
It shows how fast an object is moving at a given time.
Speed = Distance / Time
We have,
The speed of the current:
V = 3 miles per hour
Rowed with the current:
Speed = V + 3
Distance = 60 miles
Rowing against the current:
Speed = V - 3
Distance = 30 miles
Rowing with the current and against the current took the same time.
Speed = Distance / Time
Time = Distance / Speed
Now,
Time for rowing with the current = Time for rowing against the current
60 / (V + 3) = 30 / (V - 3)
2 / (V + 3) = 1 / (V - 3)
2 (V - 3) = V + 3
2V - 6 = V + 3
2V - V = 3 + 6
V = 9
Thus,
The rate of the rowing team in still water is 9 miles per hour.

Which events are independent? Select three options.
Roll a number cube, and then roll the same number cube again.
Flip a coin, and then flip the coin a second time.
Remove a card from a deck, and then remove a second card.
Draw a card from a deck, replace it, and then draw a second card.
Take a marble out of a bag, and then take a second marble out of the bag.
Answer: The first, second, and fourth.
Step-by-step explanation:
1). When you roll a cube twice, the number you get on the first roll doesn’t impact the second. As a result, it’s independent.
2). When you flip a coin twice, what you get on the first flip doesn’t impact what you get on the second. As a result, it’s independent.
3). When you remove a card from a deck, then remove a second one WITHOUT replacing the first, the first card impacts the second draw. For example, when I draw the first card, my chances of drawing a two are 1/13. If I draw a two the first time, my chances of drawing a two the second time are 1/17 (3/51. The total is fifty-one since one card is missing). Since the first draw impacted the probability of the second, the events are NOT independent.
4). When you remove a card, replace it, then draw again, your chances of drawing the same card doesn’t change. For example, my odds of drawing a three are 1/13 (or 4/52). If I draw a three the first time, then put it back and draw again, my odds are still 1/13 because I put the card back in the deck. As a result, the event is independent.
5). If I take a marble from a bag, and then take a second marble, the first draw impacts the second. For example, if a bag has three blue marbles and three green marbles, my chances of getting a blue marble the first time are 1/2 (or 3/6). If I get a blue marble and choose again, WITHOUT replacing it, my chances of choosing another blue marble are 2/5 (since one marble is missing). Since the first draw impacting the probability of the second, the events are NOT independent.

Carlos is three times as old his son. The sum of Carlos age and his sons age is 52. How old is Carlo
Answer:
39
Step-by-step explanation:
Let x = son's age
Then 3x = Carlos' age
So, x + 3x = 52
4x=52
x=13
So the son is 13 and Carlos is 3x13=39

half of 50 games= 25 games
They already won 10
So they need to win 15 more games to have 25 games (half of the 50 games)

What is an expression?Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between.
Given that, two expressions, -3y² and (-4y³+y-9) we need to find their products,
So,
= -3y² x (-4y³+y-9)
= -3y²(-4y³) -3y²(y) -3y²(-9)
= 12y⁵-3y³+27y²
Hence, the product of the expressions is 12y⁵-3y³+27y²

HOURS WORKED
Answer:
B is false.
Step-by-step explanation:
So based offf the graph, he earns about 7.50 per hour, so A is true, because 7.50(14)= 105.00 or 105, add the dollar. Meaning B has to be false.
If he works 14 hours then he will earn the amount of $105 which is true and if he works 16 hours then he will earn $120 which is true.
What is the Linear equation?A linear equation is defined as an equation in which the highest power of the variable is always one.
The given graph represents Cody's work and the amount of money he earns at his job.
According to the given graph,
We can see two points are (4, 30) and (8, 60)
The linear equation will be
⇒ y - 30 = (60-30)/(8-4)(x-4)
⇒ y - 30 = (30)/(4)(x-4)
⇒ y - 30 = 7.5(x-4)
⇒ y = 7.5x - 30 + 30
⇒ y = 7.5x
Cody's work = 14 hours then we verify the response by substituting x = 14 in the above equation,
⇒ y = 7.5(14)
⇒ y = 105
Thus, if he works 14 hours then he will earn $105
Cody's work = 16 hours then we verify the response by substituting x = 16 in the above equation,
⇒ y = 7.5(16)
⇒ y = 120
Thus, if he works 16 hours then he will earn $120.

Answer:
5b - 0.9b, distributive property
Step-by-step explanation:
The expression that is used to find the price of 5 loaves of bread is given by :
5(b-0.18b)
We need to rewrite the above expression.
Distributive property : a(b+c) = ab + ac
Here, a = 5, b = b and c = -0.18b
5(b-0.18b) = 5(b) + 5(-0.18b)
= 5b - 0.9b
So, the equivalent expression is 5b - 0.9b. The distributive property was used to rewrite the expression.
