The ratio of Zoey's money to Andrew's money is 4:5. If Zoey has $28, how much do they have altogether?

Answer: 1. 63; 2. 84; 3. 104 4. 1:2

Step-by-step explanation: Since Zoey has $28, and the ratio is 4:5, we can multiply the ratio by 7 on both sides so that it is 28:35, giving $35  for andrew, and this $28+$35=$63. Since the ratio of red to white marbles has a sum of 10, but there are 120, we multiply the ratio by 120/10=12, to make the ratio applicable to the scenario, so 7 times 12 = 84 red marbles. Same way for the theater question, 195/15=13, so 8 times 13= 104, and so 104 people are boys. For the last question you can simply divide both sides by 5 (or think of it as a fraction, 5/10=1/2).

Thx, 5 star and brainliest for first
Anastaziya [24]

In calculating this, you would have to find the unit price first.

$13 per 3 1/4 yards is also equal to $4 per yard.

Then you would have to find out the other ones' unit prices.

a) $16 per 4 2/3 yards is equal to around $2.82 per yard, so <u>No</u>

b) $11 per 2 3/4 yards is equal to $4 per yard, so <u>Yes</u>

c) $26 per 6 1/2 yards is equal to $4 per yard, so <u>Yes</u>

I solved these by dividing the amount of money by the amount of string.

Find an autonomous differential equation with all of the following properties:
tresset_1 [31]

Answer:

dy/dt = y ( 3 - y )

Step-by-step explanation:

Given data:

Determine an autonomous differential equation with the following properties

y = 0 and Y = 3

y' > 0 for  0 < y < 3

y' < 0 for  -∞ < y < 0  and  3 < y < ∞

considering an autonomous differential equation

dy/dt = y ( 3 - y )

y = 0 and 3 represents equilibrium solutions

if 0 < y < 3  then y ( 3 - y ) > 0  for   0 < y < 3

hence : dy / dt = y' > 0  for 0 < y < 3

y ( 3 - y ) <  0  for -∞ < y < 0 and  3 < y < ∞

hence : dy / dt = y' < 0  for  -∞ < y < 0  and  3 < y < ∞

this shows that the autonomous differential equation satisfies every condition hence the autonomous differential equation is :

dy/dt = y ( 3 - y )
