2 answers:

7 0

If you would like to write 45 minutes to 1 hour in the simplest form, you can do this using the following step:

1 hour = 60 minutes
45 minutes : 60 minutes = 45 : 60 = 3 : 4 (divide both numbers by 15)

The correct result would be 3 : 4.

4. Tests are performed to determine the Tool Life of a high speed steel single edge cutting tool. At a cutting speeds (v) of 180

podryga [215]

Answer:(a) n=0.233

Step-by-step explanation:

Given

We Know according to Taylor tool life

$VT^n=c$

V=cutting speed

T=tool life

n=tool life exponent

c=constant

$180\times \left ( 4.25\right )^n=110\times \left ( 35\right )^n$

$\frac{180}{110}=\left ( \frac{35}{4.25}\right )^n$

$1.636=\left ( 8.235\right )^n$

taking log both side

$\ln \left ( 1.636\right )=n\ln \left ( 8.235\right )$

n=0.233

What is the greatest possible quotient of any two distinct members of the set $\left\{\frac{2}{5}, \frac{1}{2},5,10\right\}$

MA_775_DIABLO [31]

The greatest possible quotient of two distinct members of the set is 25.

<h3>What is the Quotient?</h3>

A quotient is defined as the outcome of dividing an integer by any divisor that can be said to be a quotient. The dividend contains the divisor a specific number of times.

We are given the set of numbers as :

2/5, 1/2, 5, 10

We must choose p as the biggest number from the set and q as the smallest number from the set in order to the greatest possible quotient .

Comparing the fractions we determine :

⇒ 2/5 = 0.4,

⇒ 1/2 = 0.5

So, the smallest number is 2/5

Select p = 10, q = 2/5

To determine the quotient.

So, p/q = 10/(2/5)

⇒ p/q = 10×5/2

⇒ p/q = 50/2

⇒ p/q = 25

Hence, the greatest possible quotient is 25 in the set.

A ramp 12 feet long is leaning against a raised platform which is 5 feet above the ground. What is the distance from the ramp's

anygoal [31]

Answer:

The distance from the ramp's contact point with the ground and the base of the platform is 10.90 feet.

Step-by-step explanation:

A ramp 12 feet long is leaning against a raised platform which is 5 feet above the ground.

And

We have to determine the distance from the ramp's contact point with the ground and the base of the platform.

Since we are looking for the side of 'b' right triangle.

Please check the attached figure.

So using the Pythagorean formula:

Fora right angled triangle with sides a, and b the hypotenuse c is defined as

$c^2=a^2+b^2$

$b=\sqrt{c^2-a^2}$

$a=5$

$c=12$

$b=?$

$b=\sqrt{12^2-5^2}$

$b=\sqrt{119}$

$b=10.90$ feet

Therefore, the distance from the ramp's contact point with the ground and the base of the platform is 10.90 feet.

Karl starts the engine on his small private airplane. The engine drives a propeller with a radius of 9 feet and its centerline 1

Volgvan

Answer: The height of one propeller tip is 3.68 feet when t= 3.5 minutes.

Step-by-step explanation:

Given: The height of one propeller tip as a function of time is given by $h = 12.5 + 9 sin(750t)$ ), where h is the height in feet and t is the time in minutes.

Put t = 3.5 , we get

$h=12.5 +9 \sin (750\times3.5)\\\\=12.5+9\sin (2625)\\\\=12.5+9(-0.9802)\\\\=12.5-8.8218=3.6782\approx3.68$

Hence, The height of one propeller tip is 3.68 feet when t= 3.5 minutes.

You buy 6 apples for $33. WHat is the cost of 10 pounds of apples

Mariana [72]

10 lbs of apples will cost $55

How? Well...

First, you would need to find the unit rate, which is 5.5
You find the unit rate by simply dividing 33 by 6. Next, after you found your unit rate, you're going to multiply that by 10. We now know that 10 x 5.5= 55. Therefore, you will need $55 for 10 lbs of apples.
