Answer:
72 kg
Step-by-step explanation:
For concreatting a tower cement, sand, stones are in the ratio 1:2:4 For 144kg sand.. What amount of cement is required?
We are given the ratio
cement: sand:stones
= 1:2:4
The sum of proportion =
1 + 2 + 4 = 7
We are given the kg of sand = 144kg
Step 1
We find the total kg of cement, sand and stones = x
Using the proportion of sand,
2/7 of x = 144kg
2/7 × x = 144kg
2x/7 = 144kg
Cross Multiply
2x = 7 × 144kg
x = 7 × 144kg/2
x = 504kg
Therefore the total kg of cement, sand and stone = 504kg
Step 2
The amount of cement required is calculated as:
1/7 × 504 kg = 72 kg
Therefore, 72kg of cement is required.
Answer:
Option C) The data are discrete because the data can take on specific value.
Step-by-step explanation:
We are given the following in the question:
The numbers of languages spoken by different people.
The data would include points like English, Hindi, Marathi, and many more.
Thus, the data is discrete because the number of languages will always be expressed in whole numbers and thus it cannot take any value within an interval.
The value is calculated and not measured.
Thus, the correct answer is
Option C) The data are discrete because the data can take on specific value.
Answer:
A
Step-by-step explanation:
i stands for square root of negative 1. If you multiple i and square root of 23 you will end up with the original
Bria: 145 centimeters
Jayleen: 1.5 meters
I'm going to convert Jayleen's into centimeters:
1 meter has 100 centimeters
1.5 x 100 = 150 centimeters
so,
Bria:145 centimeters
Jayleen: 150 centimeters
So, Jayleen bought more fabric
