find two consecutive even integers such that twice the smaller is 16 more than the larger

Answers

Answer 1

Define x:
Let one of the numbers be x.
The other number is x + 2

Construct equation:
twice the smaller is 16 more than the larger
⇒2x = x + 2 - 16

Solve x:
2x = x + 2 - 16
x = -14

Find the two numbers:
Smaller number = x = -14
Larger number = x + 2 = -12

Answer: The two numbers are -14 and -12

Answer 2

Let's make an equation. X will be the smaller number while y is the bigger.
x+2=y; since they're consecutive even numbers. We will use that equation to represent y.
Twice the smaller; 2x
16 more than the larger; 16+x+2
2x=16+x+2; let's add like terms.
2x=18+x
Let's subtract x from both sides.
x=18
If the smaller number is 18, the bigger number is 20.

The two numbers are 18 and 20.

x=selling price of each soccer ball
y=daily profit from soccer balls

The vertex is located at (8.33, 236.67). What does this point represent in context?

Answers

In the figure we have the graphic of this equation. So, the vertex is the maximum of this function. This point means that the maximum daily profit from soccer balls is:

[tex]y = 236.67[/tex]

And this happens when the selling price of each soccer ball is:

[tex]x = 8.33[/tex]

So if you want to get the best daily profit, this is the price you must sell each soccer ball.

Refer the below solution for better understanding.

Step-by-step explanation:

Given :

[tex]y = -6x^2+100x-180[/tex]

where,

x = selling price of each soccer ball.

y = daily profit from soccer balls.

Solution :

The vertex shows the maximum value of y and x.

y = 236.67 shows the maximum daily profit and this happens when selling price of each soccer ball is x = 8.33.

The first painter can finish a paint job in 2 hours. The second painter can finish the same job in 8 hours. How long would it take them to finish the job if they were working together?

Answers

Final answer:

If two painters who can individually finish a painting job in 2 hours and 8 hours respectively work together, they will be able to finish the job in 1.6 hours.

Explanation:

The question is about determining how fast two painters can finish a paint job if they work together, given their individual working speeds. This is related to the field of mathematics and specifically to the concept of rates. The first painter can finish the job in 2 hours, so, his rate of working is 1/2 of the job per hour. The second painter can finish the job in 8 hours, so his rate of working is 1/8 of the job per hour. When they work together, their rates are added together. So, the combined rate of both painters is 1/2 + 1/8 = 5/8 of the job per hour. To find out how long it would take them to finish the job together, we take the reciprocal of this, which gives us 8/5 or 1.6 hours.

https://brainly.com/question/30354032

#SPJ12

Final answer:

Working together, the two painters would take approximately 1.6 hours or 1 hour and 36 minutes to finish the job.

Explanation:

To find how long it would take the two painters to finish the job together, we can use the concept of work rates. The first painter can finish the job in 2 hours, so they have a work rate of 1/2 job per hour. Similarly, the second painter can finish the job in 8 hours, so their work rate is 1/8 job per hour.

When the two painters work together, their combined work rate is the sum of their individual work rates. So, the total work rate when they work together is 1/2 + 1/8 = 5/8 job per hour.

To find the time it would take them to finish the job, we can use the formula time = 1 / work rate. Substituting in the combined work rate of 5/8 job per hour, we get:

time = 1 / (5/8) = 8/5 = 1.6

Therefore, it would take the two painters approximately 1.6 hours or 1 hour and 36 minutes to finish the job if they were working together.

the determinant is

so we have
a=-3
b=1
c=-4

so the determinant is
[tex] {1}^{2} - 4( - 3)( - 4) = 1 - 48 = - 47[/tex]
now we know if d=0 there is 1 real solution if d<0 there are complex solutions and if d>0 there are 2 real solutions.
since d=-47<0 there are no real solutions only complex ones

Final answer:

The equation has no real number solutions.

Explanation:

To find the number of real number solutions to the equation 0 = –3x² + x – 4, we can use the discriminant of the quadratic equation. The discriminant is calculated as b² - 4ac, where a, b, and c are coefficients of the equation in the form ax² + bx + c = 0. If the discriminant is positive, the equation has two distinct real solutions. If the discriminant is zero, the equation has one real solution. And if the discriminant is negative, the equation has no real solutions.

In this case, a = -3, b = 1, and c = -4. Let's calculate the discriminant:

b² - 4ac = (1)² - 4(-3)(-4) = 1 - 48 = -47

Since the discriminant is negative, the equation 0 = –3x² + x – 4 has no real number solutions.

If EFGH is a parallelogram, what is the value of x?

Answers

to be a parallogram the 2 angles shown need to equal 180 degrees

so we have: 34 + (4x-2) = 180

now we can solve for x

34 + 4x -2 = 180

simplify the left side by subtracting 2 from 34

32+4x =180

subtract 32 from each side:

4x = 148

divide both sides by 4 to get x

x = 148 / 4

x = 37

The answer is B

A quadrilateral in which opposite sides are parallel is called a parallelogram. The value of x is 37.

What is a parallelogram?

That quadrilateral in which opposite sides are parallel is called a parallelogram.

Thus, a parallelogram is always a quadrilateral but a quadrilateral can or cannot be a parallelogram.

For a parallelogram, any two adjacent angles are always supplementary. Therefore, we can write the sum of the two angles as,

(4x-2)° + 34° = 180°

4x - 2 + 34 =180

4x + 32 =180

4x = 180 - 32

4x = 148

x = 37

Hence, the value of x is 37.

The hemisphere is half the volume of a sphere. Since we are given the circumference, we can solve for the radius of the sphere. That is

[tex]116\:cm=2\pi r[/tex]

[tex]r=\frac{116}{2\pi }=18.462\:cm[/tex]

Part A
We can now compute for the volume of the hemisphere.
[tex]V=\frac{1}{2}\times \frac{4}{3}\pi r^3=\frac{1}{2}\times \frac{4}{3}\pi \left(18.462\right)^3=13179\:cm^3[/tex]
