if a+b+1.5 is an even integer what is the next consecutive integer
The next consecutive even integer represented by the statement is a + b + 3.5
How to determine the next consecutive integers?The statement in the question is represented as
a+b+1.5 is an even integer
As a general rule of numbering;
Consecutive integers are integers that have a difference of 1These numbers can be negative or positiveIn this case, the integers have a difference of 2
This is so because, they are even integers and even integers have a difference of 2
Solving further, we can represent the integer with x
So, we have
Current integer = a+b+1.5
Rewrite properly
This gives
Current integer = a + b + 1.5
Recall that:
even integers have a difference of 2
This means that
Next consecutive integer = Current integer + 2
Substitute the known values in the above equation, so, we have the following representation
Next consecutive integer = a + b + 1.5 + 2
Evaluate the sum in the above equation
Next consecutive integer = a + b + 3.5
Hence, the next integer is a + b + 3.5

The correct answer to inequality is option A .
What is inequality equation?
The mathematical expressions with inequalities area unit those with unequal sides on each side.
Main body:
For this case we have the following inequality:
-4(x+3)≤ -2 -2x
Applying distributive property on the left side we have:
-4x - 12≤ -2 -2x
Adding 2x to both sides of the inequality we have:
-4x +2x -12 ≤-2
-2x-12≤-2
Adding 12 to both sides of the inequality we have:
-2x-12 +12≤ -2 +12
Dividing by 2 to both sides of the inequality:
-2x ≤ 10
Multiplying by -1 on both sides, taking into account that the sense of inequality changes:
x≥ -10/2
x ≥ -5
hence, the solutions are given by all values greater than or equal to -5.
so , option A is correct.

What is full answer for density?
A material substance's density is defined as its mass per unit volume. Density is defined as d = M/V, where M stands for mass, and V for volume. The unit of density that is most frequently used is grams per cubic centimeter.We determine the volume, V, corresponding to the given amount of gold. We do this by dividing the given mass, m, by the density, d, such that
V = m/d
m = 31.03 g
d = 19.3 g/ml
We proceed with the solution
V = m/d
= 31.03/19.3

If he only has $300 to spend, how many people can he invite to his party? Write and solve the equation for the above problem. What is the maximum number of people Eddy can invite?
The maximum number of people Eddy can invite is 37.
How to illustrate the equationThe equation is simply used to show the relationship between the variables given.
In this case, it is going to cost him $150 to cater the party, plus $4 per person for drinks and he only has $300 to spend.
Let the number of persons be represented by p
The equation will be:
150 + (4 × p) = 300
150 + 4p = 300
Collect like terms
4p = 300 - 150
4p = 150
Divide
p = 150 / 4
p = 37.5

What is the equation in point slope form of the line that passes through the point (−1, −3) and has a slope of 4?
A. y+3=4(x+1)
B. y−1=4(x−3)
C. y+1=4(x+3)
D. y−3=4(x−1)
Answer:
A. y+3=4(x+1)
Step-by-step explanation:
Lets find an equation having the form y=mx+b, where m is the slope and b the y-intercept. We are given the slope, so let's add that first:
y = 4x + b
That was easy. No how can we find the value for b? We are given a point that the line passes through: (-1,-3). If the line gors through this point, then it must be a valid solution to the equation. Let's use that point in the equation and solve for b:
y = 4x + b
-3 = 4*(-1) + b for point (-1,-3)
-3 = -4 + b
b = 1
The equation becomes y = 4x + 1
Put this into point slope form:
y = 4x + 1
y+3 = 4x + 1 + 3
y+3 = 4x + 4
y+3 = 4(x + 1)

In this figure, AB∥CD and m∠3 = 114°.
What is m∠6?
Answer:
66
Step-by-step explanation:
180 - 114) These angles are supplemental. They add to 180
66
Answer:
m<6=66°
Step-by-step explanation:
Because m<2 and m<3 are both on a straight line, we know they must add to 180°:
m<2 + m<3 =180
We know m<3=114°, so:
m<2 +114 = 180
m<2 = 66
Since AB|CD, m<2 and m<6 are corresponding angels, making them equal, and so m<6=66°.
Lance is a part-time employee at Subway. One M-W & Friday he works from 4pm-9pm with a non paid 30 minute lunch. On Saturday he works from 12pm til 6pmwith a non paid thirty minute lunch. If he earns $11.75 per hour, how many hours and minutes has he worked and what is his gross pay.
Lance had a gross pay of $117.5 working on Friday and Saturday
How is his gross payTo determine his gross pay, we have to find the number of hours he worked and multiply it by his hourly wage.
This can be done by;
4pm - 9pm = 5 hours.
But he had a non-paid 30 minutes break which will give us his work hours on Friday as 4 hours 30 minutes or 4.5 hours.
On Saturday, he worked from 12pm - 6pm which will give us a work time of 6 hours. He also took a non-paid 30 minutes lunch and his total work time on Saturday is 5 hours 30 minutes or 5.5 hours.
If we add the total numbers of hours worked, we will get
4.5 + 5.5 = 10 hours.
Now we can multiply this by the hourly wage.
10 * 11.75 = 117.5
His gross pay is $117.5

The uniform rate of water flowing of a certain pipe is 75 litres per minute. Find the time taken in minute fill a tank having the capacity of 1.5m³
The time taken in minutes to fill a tank having a capacity or work of 1.5m³ is 1.2 minutes;
What are Time and Work?
According to fundamental mathematical concepts, time may be described as the amount of time that a specific activity occurs, whereas work can be described as the collection of actions carried out in order to attain a specific activity or outcome. It should go without saying that time is needed to accomplish a task. It implies that time and work have a certain relationship.
The task completed is calculated as the sum of the number of people participating in the work and the number of days it took to finish. The fundamental time and work equation is W = N X D.
W is the amount of work done.
N is the number of people.
D is the number of days or hours needed.
In the question, It is given that:
water flowing off a certain pipe is 75 liters per minute;
and;
the tank has a capacity of 1.5m³
First converting the Efficiency in liters per second,
So,
water flowing off a certain pipe is 75 liters per minute;
So, dividing it by 60 ;
Water flowing off the pipe = 1.25;
Now using the work-time relationship:
Efficiency × Time = work;
So,
1.25×Time = 1.5
⇒Time = 1.2
So, the time taken in minutes to fill a tank having a capacity of 1.5m³ is 1.2 minutes;
Hence,
the time taken in minutes to fill a tank having a capacity of 1.5m³ is 1.2 minutes;

Any piece of luggage must have a length, width, and height combined that is less than or equal to 150 cm. A traveler requests to take a package with the maximum permitted volume. if the length and width are to be equal, then the dimensions would be 48*96*72
Any piece of luggage must have a length, breadth, and height combined that is 216 cm or less.
L+W+H=216 (because we want the max volume, we may ignore the "less than part" and set them equal) (since we want the max volume, we can ignore the "less than part" and set them equal)
L = W if the length and width are equal.
Let's construct this new equation by swapping L for W.
