Mark and Tony share a sum of money in the ratio 3:5. What fraction of the money did Tony ratio receive?

1 answer:

4 0

Answer:

Part A is 3/8 of the whole
Part B is 5/8 of the whole

Solution:
Assuming there are no other parts,
the Whole = A + B is the denominator:
Whole = 3 + 5 = 8

Part A = 3 and Part B = 5 are numerators for each fraction.

The fractions are then:
3/8 and 5/8

Meaning:
Part A is 3/8 of the whole
Part B is 5/8 of the whole

If a wheel with a radius of 50 inches spins at a rate of 500 revolutions per minute, find the approximate linear velocity in mil

Artyom0805 [142]

Answer:

The linear velocity in miles per our is 14789400 mph .

Step-by-step explanation:

Given as :

The radius of wheel = 50 inches

So, the diameter of wheel = 2 × radius = 2×50 = 100 inches

Or, Diameter = 100 × 1.57 miles = 157 miles

The number of revolution per minutes = 500 RPM

or, The number of revolution per hours = 500 × 60 = 30,000 RPH

Now, Circumference of wheel = $\pi$ ×diameter

Or, C = 3.14 × 157 = 492.98 miles

So, Distance cover by wheel = C × RPH × Time in hour

or, D = 492.98 × 30,000 × Time in hour

And Velocity = $\dfrac{\textrm Distance in miles }{\textrm Time in hour}$

or, V = $\dfrac{\textrm 492.98 × 30,000 × Time in hour }{\textrm Time in hour}$

or, V = 14789400 miles per hour

Hence The linear velocity in miles per our is 14789400 mph . Answer

Resolve into factor.. Please solve this by step by step ...

lys-0071 [83]

Answer:

9x^4 + 2x²y² + y^4

Arrange the terms

9x^4 + y^4 + 2x²y²

making the first two terms into a² + b²

(3x²)² + (y²)² + 2x²y²

use the formula of a² + b² = (a+b)² - 2ab

(3x² + y²)² - 2.3x².y² + 2x²y²

(3x² + y²)² - 6x²y² + 2x²y²

(3x² + y²)² - 4x²y²

(3x² + y²)² - (2xy)²

use the formula a² - b²

(3x² + 2xy + y²) (3x² - 2xy + y²)
