Hey there! I'm happy to help!

To find the number halfway between two numbers, you simply add them and then divide by two.

1.4142133+1.41422=2.8284333

2.8284333/2=1.41421665

That is one number in between these two. Now, we can find the number in between the middle number and the second number. This is another number in between our two numbers.

(1.41421665+1.41422)/2=1.414218325

You could keep on doing this and find tons of numbers in between these two.

Therefore, two numbers between 1.4142133 and 1.41422 are 1.41421665 and 1.414218325.

Have a wonderful day! :D

Answer:

The product of the square root of a prime number and a nonzero rational number is a irrational number.

Step-by-step explanation:

Given that,

When is the product of the square root of a prime number and a nonzero rational number a irrational number.

We know that,

Prime number :

Prime number is that number whose has a two factor. first factor is one and second is themselves.

The square root of a prime number is irrational number.

Rational number :

Rational number is that number which is in fraction form.

For example : [tex]\dfrac{p}{q}[/tex]

Here, p and q are integers

We need to proof the product of  the square root of a prime number and a nonzero rational number is a rational number

Using given data

Suppose, the square root = √5

Rational number  = [tex]\dfrac{2}{3}[/tex]

We need to calculate the product of the square root of a prime number and a rational number

Using formula of product

[tex]R=P\timesQ[/tex]

Where, P = square root of a prime number

Q= rational number

Put the value into the formula

[tex]R=\sqrt{5}\times\dfrac{2}{3}[/tex]

[tex]R=\dfrac{2\sqrt{5}}{3}[/tex]

Hence, The product of the square root of a prime number and a nonzero rational number is a irrational number.

Let the number of cards equal x.

Set up an equation for both companies, set equal to each other and solve for x.

0.10x + 12 = 0.12x + 10

Subtractb0.10x from both sides:

12 = 0.02x + 10

Subtract 10 from both sides:

2 = 0.02x

Divide both sides by 0.02:

X = 2/0.02

X = 100

100 cards would be the same price for both companies.

Answer:

C

Step-by-step explanation:

40+20=60

A.10(4+2) = 60

B.5(8+4) = 60

C.4(10+16) = 104

D.2(20+10) = 60

Answer:C

Step-by-step explanation:

First we find out what 40+20 is which is 60

So now we go through each choice to see if any doesn’t equal 60

A.10(4+2)

10*6=60

B.5(8+4)

5*12=60

C.4(10+16)

4*26=104

D.2(20+10)

2*30=60

As you can see C is 104 not 60 so c is the answer

Step-by-step explanation:

sorry if its wrong

Answer:

By using the energy conservation law, the input energy must be equivalent to the output energy.  If you measured output energy is lower than your input energy, you have lost that difference of energy either in mechanical inefficiency (friction, heat, etc.) or an energy sink.

Thus, the energy not output by the machine is lost in the process within the machine.

Answer:

6 markers

Step-by-step explanation:

5000/800 = 6.25

We can't have a quarter of a marker

If we were to round up it would have to be 5.6 km to fit 7 so we have to round down, and the answer is 6

In addition, along the 5000 m trail there will be one at 800, 1600, 2400, 3200, 4000, and 4800

We can only fit 6 of them along the trail if they are spaced 800 m apart so 6 markers will be able to fit on a 5k trail

Answer:

We need to calculate how many times there are 800 meters on 5000 meters.

To know so, we can divide 5000 by 800:

5000/800 = 6.25

So now, we know there are 800 meters 6.25 times on this trail.

So, how many markers have to be used? There have to be used 6, as the other 0.25 times will be the last 200 meters of the trail (800*0.25) and we only have to put a mark each 800.

We can also do this manually, from the start:

First mark would be at 800, next at 1600, next at 2400, next at 3200, next at 4000 and the last one at 4800. As we have said, 6 markers.

Answer:

The conditional form of this statement is false.

Step-by-step explanation:

Angles that are less than 90°, also known as right angle, are known as acute angles.

So, any angle that has a measure between 0° and 90° are known as acute angles.

The statement provided is:

"An angle with a measure of 88° is an acute angle."

The conditional form of this statement provided is:

"If an angle is an acute angle, then its measure is 88°."

This statement is false.

This is because an acute angle can measure between 0° and 90°.

It is not necessary that the measure of an acute angle is 88°.

Thus, the conditional form of this statement is false.

Answer:

this angle would be acute

Step-by-step explanation:

why? because its less than 90 in which means it acute.

Answer:

The time it would take to inflate the balloon to approximately two-thirds of its maximum volume is approximately 46.90 minutes

Step-by-step explanation:

The given parameters are;

The diameter of  the balloon  = 55 feet

The rate of increase of the radius of the balloon when inflated = 1.5 feet per minute

We have;

dr/dt = 1.5 feet per minute = 1.5 ft/min

V = 4/3·π·r³

The maximum volume of the balloon = 4/3 × 3.14 × 55³ = 696556.67 ft³

When the volume is two-thirds the maximum volume, we have;

2/3 × 696556.67 ft³ = 464371.11 ft³

The value of the radius, r₂ at that point is found as follows;

4/3·π·r₂³ = 464371.11 ft³

r₂³ = 464371.11 ft³ × 3/4 = 348278.33 ft³

348278.333333

r₂ = ∛(348278.33 ft³) ≈ 70.36 ft

The time for the radius to increase to the above length = Length/(Rate of increase of length of the radius)

The time for the radius to increase to the above length ≈ 70.369 ft/(1.5 ft/min) ≈ 46.90 minutes

The time it would take to inflate the balloon to approximately two-thirds of its maximum volume ≈ 46.90 minutes.

Answer:

c.) x = -3

Step-by-step explanation:

Solve for x:

-10 x = 2 (9 - 2 x)

Hint: | Write the linear polynomial on the left hand side in standard form.

Expand out terms of the right hand side:

-10 x = 18 - 4 x

Hint: | Move terms with x to the left hand side.

Add 4 x to both sides:

4 x - 10 x = (4 x - 4 x) + 18

Hint: | Look for the difference of two identical terms.

4 x - 4 x = 0:

4 x - 10 x = 18

Hint: | Combine like terms in 4 x - 10 x.

4 x - 10 x = -6 x:

-6 x = 18

Hint: | Divide both sides by a constant to simplify the equation.

Divide both sides of -6 x = 18 by -6:

(-6 x)/(-6) = 18/(-6)

Hint: | Any nonzero number divided by itself is one.

(-6)/(-6) = 1:

x = 18/(-6)

Hint: | Reduce 18/(-6) to lowest terms. Start by finding the GCD of 18 and -6.

The gcd of 18 and -6 is 6, so 18/(-6) = (6×3)/(6 (-1)) = 6/6×3/(-1) = 3/(-1):

x = 3/(-1)

Hint: | Simplify the sign of 3/(-1).

Multiply numerator and denominator of 3/(-1) by -1:

Answer: x = -3

The length of the other leg is 13.1

Given.

The length of the hypotenuse of a right triangle is 30 inches.

The length of one leg is 27 inches.

To the nearest tenth, we need to find the length of the other leg.

It states that in a right-angled triangle the square of the hypotenuse is equal to the square of the other two sides.

We have,

Length of the hypotenuse = 30 inches.

Length of One leg = 27 inches.

Let the length of the other leg be x.

Now,

Applying the Pythagorean theorem.

30² = 27² + x²

900 = 729 + x²

Subtracting 729 on both sides

900 - 729 = 729 + x² - 729

171 = x²

x² = 171

x = 13.07669

Rounding to the nearest tenth

We get,

x = 13.1

Thus the length of the other leg is 13.1

Answer:

Step-by-step explanation:

360 - (76×2) = 208

208 ÷ 2 = 104°

Answer:

1.  y = (-5x/2) + -3

2. y = (3x/2) + 7

Step-by-step explanation:

For both these problems, we simply need to apply point-slope form.

1.  The point (0, -3) and the slope that is perpendicular to the line is the reciprocal of the coefficient, slope = -5/2.

From here, we simply apply the formula:

y - y0 = m ( x - x0)

y - -3 = -5/2 ( x - 0 )

y + 3 = -5/2 x

y = (-5x / 2) + -3

2.  The point (0, 7) and the slope that is parallel to the line must maintain the same slope.  First, we need to rewrite the equation into slope-intercept:

-3x + 2y = 10

2y = 3x + 10

y = 3x/2 + 5

Now we want to apply the point-slope form

y - y0 = m ( x - x0 )

y - 7 = (3/2) (x - 0)

y - 7 = 3x / 2

y = 3x/2 + 7

Answer:

a. y(t) = - 1/2gt² + y₀ b. [tex]t = \frac{v_{0} +/- \sqrt{v_{0} ^{2} + 2 y_{0}g } }{g }[/tex]

Step-by-step explanation:

Let the quadratic function y(t) = v₀t - 1/2gt² + y₀ represent the quadratic function that models the height above the ground of the projectile.

a. Maximum Height

At maximum height, the velocity, v₀ = 0, so substituting v₀ = 0 into the equation, we have

y(t) = v₀t - 1/2gt² + y₀

y(t) = 0 × t - 1/2gt² + y₀

y(t) = 0 - 1/2gt² + y₀

y(t) = - 1/2gt² + y₀

b. Time when the projectile reaches the ground

The time when the projectile reaches the ground is gotten when y(t) = 0, So

y(t) = v₀t - 1/2gt² + y₀

0 = v₀t - 1/2gt² + y₀

re-arranging, we have

1/2gt² - v₀t - y₀ = 0

Using the quadratic formula,

[tex]t = \frac{-(-v_{0}) +/- \sqrt{(-v_{0}) ^{2} - 4 X (-y_{0}) X\frac{g}{2} } }{2 X \frac{g}{2} } \\= \frac{v_{0} +/- \sqrt{v_{0} ^{2} + 2 y_{0}g } }{g }[/tex]
