Acereal mixture contains rice, wheat and corn in the ratio of 3: 7: 9. how many kilograms of mixture are there if it contains 2.1 kg of wheat?

Total cereal mixture is 5·7 kg

Step-by-step explanation:

A cereal mixture contains in rice , wheat and corn

In a ratio of rice, wheat and corn is  

let the number be x

Rice    3x

Wheat    7x

Corn  9x

Total cereal mixture is 19x

Wheat 2·1 kg

So, Wheat 7x equals to 2·1 kg

7x 2·1 kg

x kg

x 0·3 kg

Total cereal mixture is 19x

19 ₓ 0·3  5·7 kg

2 & 7

step-by-step explanation:

he climbs 300 ft/hr at a constant rate. the peak is at 1,500 ft.

when going up, he reaches 600 ft in 2 hours. remember, that he is going in a constant rate. divide 600 with 300:

600/300 = 2

assuming that he takes the same route back (meaning that it's a 1500 ft route back, you can solve.

note also that you are solving when he gets back to 600 ft after he reaches the peak.

first, find the amount of hours it takes to get up the peak. divide the total amount (1500), with the ft/her (300) to get the amount of hours (x):

1500/300 = x

x = 5

it takes jamie 5 hours to get up. now, he is returning down, and reaches 600 (his current destination). remember that he climbs at a constant 300 ft/hr. divide 600 with 300:

600/300 = x

x = 2

now add the two numbers together.

x = 5 + 2 = 7

jamie takes 7 hours to go up the mountain and reach his current position when descending.

(total amount/constant rate) = (time).

remember that it is a constant rate, so in total, when he gets back down the mountain, it will take the same amount of time as when he goes up. the total amount for the round trip is: 5 + 5 = 10.
