<span>1. The problem says that the is ratio 1:3:5 by weight and Talil wants to make 180 kg of concrete mix.

 2. Therefore, you have:

 1+3+5=9

 180 kg/9=20 kg

 3. Each of the 9 parts of the ratio weights 20 kg. So, to make 180 kg of concrete mix, he needs:

 1x20 kg=20 kg of cement
 3x20 kg=60 kg of sand
 5x20 kg=100 kg of gravel

 4. Talil has:

 15kg of cement (Not enough)
 85kg of sand (More than enough)
 100kg of gravel (Enough)
</span><span>
 Does Talil have enough cement , sand and gravel to make concrete mix?
</span><span>
 The answer is: No, she does no have </span>enough cement , sand and gravel to make concrete mix.

Geometric or arithmetic<br> 4,10,16,22
skad [1K]

Answer:

arithmetic

Step-by-step explanation:

An arithmetic sequence has a common difference d between consecutive terms.

22 - 16 = 6

16 - 10 = 6

10 - 4 = 6

A common difference of 6 exists between consecutive terms.

Thus the sequence is arithmetic.

City A's population of 1115000 is decreasing at a rate of 15000 per year. City B's population of 698000 is increasing at a rate
vredina [299]

Answer:

7 years

Step-by-step explanation:

Let x  be number of years the populations be equal

City A's population of 1115000 is decreasing at a rate of 15000 per year.

The population is decreasing at a constant rate so we use equation

y= mx + b

where m is the slope(rate), b is the initial population

m= -15000 (decreasing) , b= 1115000

y= -15000 x + 1115000

City B's population of 698000 is increasing at a rate of 45000 per year.

m= 45000 (increasing) , b= 698000

y= 45000 x + 698000

Now we set the equations equal and solve for x

45000 x + 698000 = -15000 x + 1115000

Add 15000 on both sides

60000 x + 698000 = 1115000

Subtract 689000 on both sides

60000 x = 417000

Divide by 60000 on both sides

x= 6.95

So after 7 years the population will be equal.

Help anyone? please?
ValentinkaMS [17]

Answer:

x=11.2

Step-by-step explanation:

Set up a proportion:

x+11/36 = 37/60

Cross multiply:

1332=60(x+11)

Distribute:

1332=60x+660

Subtract 660 from 1332

672=60x

Divide:

x=11.2

I'm not sure if this is the correct answer but I hope this helps! :)

Correct me if I'm wrong!
