Mathematics
1 answer:
Mkey [24]2 years ago
4 0

Answer:

48 and 75

Step-by-step explanation:

Given data

We are given that the ratio is 4:5

we have two numbers, the bigger and the smaller number

case one: bigger= 60

the smaller is

4/5= x/60

5x= 60*4

5x= 240

x= 48

case two: smaller number = 60

4/5=60/x

4x= 60*5

4x= 300

x= 300/4

x= 75

Hence the two possible numbers are 48 and 75

Round 0.5289 to the nearest thousandth.
Anit [1.1K]

Answer:

0.5289 to the nearest thousandth is 0.529.

Step-by-step explanation: If a number is less than 5, round down, but if a number is 5 or more, round up. The digit after the thousandths place is the digit we should look at to answer the question and it is 9, so we round up from 0.528 or 0.529. So, the answer is 0.529.

(w-w^2)^4=?<br>.......................​
Setler [38]

Answer:

w^8 - 4w^7 + 6w^6  - 4w^5 + w^4 .

Step-by-step explanation:

(w - w^2)^4

= w^4 ( 1 - w)^4

By the binomial theorem:

= w^4( 1  - 4w + 6w^2 - 4w^3 + w^4)

= w^4 - 4w^5 + 6w^6 - 4w^7 + w^8

=  w^8 - 4w^7 + 6w^6  - 4w^5 + w^4 ( Standard form).

What is the unit rate of 15 laps in 3 days
Ivanshal [37]
The answer is going to be 5 laps per day because I did 15 laps/3days and divided each side by 3 which the answer is going to be 5/1 but it’s basically 5 since it’s going to be a whole number in this set. Therefore the unit rate of 15 laps in 3 days is going to be 5 laps per day.

Alla and balla together drink 750ML of water. Of alla drinks 50% more than balla how much does Alla drink
Akimi4 [234]

Answer:

450 ml.

Step-by-step explanation:

Let x be the amount of water drank by Alla and y be the amount of water drank by Balla.

We have been given that Alla and Balla together drink 750 ML of water. We can represent this information as:

x+y=750...(1)  

We are also told that Alla drinks 50% more than Balla. We can represent this information as:

x=1.5y...(2)

From equation (1) we will get,

y=750-x  

Upon substituting this value in equation (2) we will get,

x=1.5(750-x)

Upon distributing 1.5 to right hand side of the equation we will get,

x=1125-1.5x

Upon adding 1.5x to both sides of equation we will get,

x+1.5x=1125-1.5x+1.5x

2.5x=1125

Let us divide both sides of our equation by 2.5.

\frac{2.5x}{2.5}=\frac{1125}{2.5}

x=450

Therefore, Alla drank 450 ml of water.
