Answer:
A. The Fabric
Step-by-step explanation:
By definition and experimental unit is the entity which is subjected to different types of treatments during the experiment.
Here the fabric has been stained with different types of stains and and then have been treated with baking soda and bleach under different temperature environments. In the experiment each time the fabric has been given different treatment than the previous one. That's why the fabric is experimental unit in the experiment mentioned in the question.
1. Multiply 5 by 2 since the piece is twice as long. That is 10.
Multiply 4 by 3 since the piece is 3 times as long. That is 12.
Her piece is 10 x 12.
2 sides of 10 & 2 sides of 12.
Multiply 10 & 12 by 2 to get 20 and 24. Add them together to get 44 inches, which is the perimeter.
2. Multiply 4 x 2 since length is twice width. That is 8.
Multiply 8 x 4 to get the area of the red paper. That is 32.
Multiply 3 x 7 to get the area of the blue paper. That is 21.
Subtract 21 from 32 to get the amount of red paper that wasn't covered up.
11 square cm were not covered up.
Hope this helps!
Answer:
x = 16
Step-by-step explanation:
The sum of measures of these three angles of any triangle is equal to 180 °
54 + 90 + (2x + 4) = 180
144 + 2x + 4 = 180
148 + 2x = 180
2x = 180 - 148
2x = 32
The function that takes three decimal numbers as inputs and finds the sum of those inputs and returns the sum has been given below
What is programming?
Program is the set of instructions given to the computer so that the computer can execute those instructions. The act of writing program is called programming.
The program has been shown below
#include<stdio.h>
using namespace std;
int main()
{
double n1, n2, n3;
double s;
printf("Enter first numbers");
scanf(%lf, &n1);
printf("Enter second numbers");
scanf(%lf, &n2);
printf("Enter third numbers");
scanf(%lf, &n3);
s = n1 + n2 + n3;
printf("Sum = %f", s);
return 0;
}
