find three consecutive integers such that the sum of twice the second and three times the third is five less than six times the first.
Answers
Answer:
13, 14, 15
Step-by-step explanation:
The three integers are consecutive so let those integers be x, (x+1), (x+2)
As per the question,
2(x+1) + 3(x+2) = 6x-5
or, 2x+1+3x+6 = 6x-5
or, 8+5 = 6x-5x
or, x = 13
So, x+1 = 13+1 = 14
x+2 = 13+2 = 15

The probability of at least one boy named Jack is (c) 1 - (9/10 x 9/10 x 9/10 x 9/10 x 9/10 x 9/10)
How to determine the probability of at least one boy named JackFrom the question, we have the following parameters that can be used in our computation:
P(Jack) = 1/10
Number of boys = 6
Using the complement rule of probabilities, we have
P(At least one Jack) = 1 - P(No jack)
Where
P(No jack) = (1 - P(Jack))⁶
So, we have
P(No jack) = (1 - 1/10)⁶
Evaluate
P(No jack) = (9/10)⁶
Substitute the known values in the above equation, so, we have the following representation
P(At least one Jack) = 1 - (9/10)⁶
Evaluate
P(At least one Jack) = 1 - (9/10 x 9/10 x 9/10 x 9/10 x 9/10 x 9/10)
Hence, the probability is (c) 1 - (9/10 x 9/10 x 9/10 x 9/10 x 9/10 x 9/10)

given the vector a⃗ =3.0i^+1.5j^, find a vector b⃗ that is perpendicular to a⃗ .
Answers
1.5i^- 3j^ is the perpendicular vector to the vector 3.0i^+1.5j^
What is perpendicular vector?Whenever there is a 90 degree angle between two vectors, they are said to be perpendicular. Two perpendicular vectors dot product is zero. and dot product is scaler product of 2 vectors.
Let b = xi^+ yj^ be the perpendicular vector to a vector
and we know that 2 vectors are perpendicular if thier dot product is 0
so it implies that
b.a(dot product) =0
=> (3i^+1.5j^) . (xi^+yj^)=0
=> 3xi^.i^+ 3y i^.j^ +1.5xj^.i^+1.5yj^j^=0
=>3x+1.5y=0 ----(i)
becaus i^.j^=0 and j^.i^0
=> x= 1.5 and y=-3 satisfies equation (i).
so the perpendicular vector is 1.5i^- 3j^

Carly took a total of 15 quizzes over the course of 5 weeks. How many weeks of school will Carly have to attend this quarter before she will have taken a total of 24 quizzes? Assume the relationship is directly proportional.
Answers
Answer:
Carly will have to attend school for 8 weeks before she takes a total of 24 quizzes.
Step-by-step explanation:
To determine the number of weeks Carly will have to attend school before she takes a total of 24 quizzes, we need to first calculate the proportion of quizzes taken to weeks attended by dividing the number of quizzes taken by the number of weeks attended:
Proportion = Number of quizzes taken / Number of weeks attended
Proportion = 15 quizzes / 5 weeks
Proportion = 3 quizzes / week
Next, we can use this proportion to calculate the number of weeks Carly will have to attend school before she takes 24 quizzes by multiplying the number of quizzes Carly wants to take by the reciprocal of the proportion:
Number of weeks = Number of quizzes / Proportion
Number of weeks = 24 quizzes / 3 quizzes/week
Number of weeks = 8 weeks
Therefore, Carly will have to attend school for 8 weeks before she takes a total of 24 quizzes.

a roof has a 5:12 pitch and the roof is 175" horizontally from the ridge to the edge , what is the height of the roof from the lowest point to the highest point?
Answers
When a roof has a pitch of 5 : 12 and the roof is 175'' horizontally the height of the roof from the lowest point to the highest point is solved to be 73''
How to determine the roof's heightThe idea of the slope is represented in the form 5: 12 when calculating the height of the roof.
This indicates that there is a 5 increase for every 12 units.
The rise is equal to 5, and the run is 12.
The vertical is the ascent, and the run is the horizontal.
It is possible to compare using the provided ratio as follows.
Let x represent the rise so that
x / 175" = rise / run = 5 / 12
x / 175" = 5 / 12
cross multiplying
175 * 5 = 12x
12x = 875
x = 875 /12
x = 72.92 ''
The height of the roof, measured from its lowest to its highest point, is calculated to be 73 inches.

It’s a hot summer day. Darius is babysitting and has promised his sweet little sister that he will fill her wading pool. He plans to soak his feet in the water as he sips a cool soda and watch little sister as she plays in the water. Sounds great, right? All he needs to do is get the pool filled. Unfortunately, little sister is impatient and starting to whine. Darius has a hose ready in the backyard to fill the pool, but he decides he will also drag the hose from the front-yard, so the two hoses can work together to fill the pool faster. Nobody wants their darling little sister to be unhappy!
Darius knows from experience that if he only uses one hose at a time, the front-yard hose takes 10 minutes longer to the fill the pool than the back-yard hose. With the two hoses working together, the pool is filled in 12 minutes. Once Darius is comfortable with his toes dangling in the water, he starts to wonder how long it would have taken to fill the pool if he had only used one of the hoses.
Darius thinks, “Hmmm. Usually when I think about how long it takes to do something I have to think about the rate it is going.”

The graph of g is the graph of f translated 3 units right. Option C is the answer
How determine how the graphs of f(x) = 2x + 1, and g(x) = 2(x + 3) + 1 compare?In geometry, a translation is a type of transformation that involves moving a geometric figure from one location to another without changing its size, shape, or orientation.
Remember, in the cartesian plane or graph, the movement in x-axis is either to the left (negative) or right (positive).
Since f(x) = 2x + 1, looking at g(x) = 2(x + 3) + 1, you will notice that 3 is added to the value x. This is a movement in the positive x-axis (right translation) and the translation is by 3 units.
