Tell whether the ratios form a proportion. 25/16 , 65/56

Mathematics

Answer:

The two ratios given: 25/15 and 65/56 do not form a proportion.

Step-by-step explanation:

A proportion is formed when two ratios (or fractions) are equal.  When you set the two ratios equal to each other:

\frac{25}{56} = \frac{65}{56}

You can then determine if they are equal by a few different methods.  (1) You can cross-multiply the numbers and see if they are equal:

25 x 56 = 16 x 65   or 1040 ≠  1400

You can also see if the numerators and denominators can be divided to form a common factor:

65 ÷ 25 = 2.6  and 56 ÷  16 = 3.5

Since neither the products of cross-multiplication or the factors by division are equal, these two ratios do not form a proportion.

PLEASE SOLVE DUE RIGHT NOW!!!!!!!!!!!!
erma4kov [3.2K]

Solution:

<u>We know that:</u>

Area \ of \ triangle = \dfrac{1}{2} \times Base \times Height

<em>Since we are already given the base and the height, we can substitute them into the formula to find the area of the triangle.</em>

Area \ of \ triangle = \dfrac{1}{2} \times 18 \times24

<u>Cancel out the "2" by dividing it by 18.</u>

Area \ of \ triangle =  9 \times24

<u>Simplify the multiplication.</u>

\bold{Area \ of \ triangle =  216 \ ft^{2}}

The volume of a gas is 10.0 liters and its pressure is 1.5 atm. If the pressure is decreased to 0.75 atm,
JulsSmile [24]

Answer:

The new volume is 20litres

Step-by-step explanation:

This problem bothers on the expansion of gases

According to Boyle's law

The volume of a given mass of gas at constant temperature is inversely proportional to the pressure

P∝1/v

Pv= constant

Given data

P1= 1.5atm

v1 = 10 litter

P2=0.75atm

v2=?

Applying P1v1= P2v2

v2= P1v1/P2

v2= 1.5*10/0.75

v2= 15/0.75

v2= 20litres
