Four times the larger of two numbers is equal to seven times the smaller. The sum of the number is 22. Fine the number

GenaCL600 [577]

4y=7x
The sum of the numbers is 22
so, x+y=22
x=(22-y)
by substitute (22-y) for x in the first equation.

if i want the track to have a circumference of 400 feet what does the diameter of the track need to be?

natta225 [31]

Answer:

The diameter of the track needs to be 127.27 feet

Step-by-step explanation:

* Lets explain how to solve the problem

- The circumference of any circle is C = 2πr, where r is the radius

of the circle and π is the constant ratio between the

circumference and the diameter of the circle which

approximately is 22/7 or 3.14

- The diameter of any circle is twice its radius

* Lets solve the problem

- The circumference of the track is 400 feet

∵ The circumference = 2πr

∵ π = 22/7

∴ 400 = 2 × 22/7 × r

∴ 400 = 44/7 r

- Divide both sides by 44/7 to find r

∴ r = 63.63

∵ The diameter of the circle = 2r

∵ The radius = 63.63 feet

∴ The diameter = 63.63 × 2 = 127.27 feet

* The diameter of the track needs to be 127.27 feet

368.54 = ( _ x 100) + ( _ x 10) + ( _ x 1/10) + ( _ x 1/100)

SCORPION-xisa [38]

Answer:

$368.54 = 3*100 + 6.8*10 +5*1/10 + 4*100$

Step-by-step explanation:

Given

$368.54 = ( [\ ] * 100) + ( [\ ] * 10) + ( [\ ] * 1/10) + ( [\ ] * 1/100)$

Required

Fill in the gap

The number can be expressed as:

$368.54 = 300 + 60 + 8 +0.5 + 0.04$

Factorize:

$368.54 = 3*100 + 6*10 + 0.8*10 +5*1/10 + 4*100$

Factor out 10 in 6 * 10 + 0.8 * 10

$368.54 = 3*100 + [6 + 0.8]*10 +5*1/10 + 4*100$

$368.54 = 3*100 + 6.8*10 +5*1/10 + 4*100$
