Answer:
3.6cm cubed
Step-by-step explanation:
First solve for both glasses' volumes.
Use l×w×h to plug in the numbers:
3.1×2×3=18.6
3.7×2×3=22.2
then subtract= 3.6
Answer:
20x - 16
Step-by-step explanation:
We can first do 1/2 (36x - 14), getting 18x - 7.
Then our expression becomes 18x - 7 + 2x - 9.
We can combine like terms, getting 20x - 16.
Answer:
Step-by-step explanation:
#include <stdio.h>
int main()
{
int num1, num2, flag_var, i, j;
/* Ask user to input the from/to range
* like 1 to 100, 10 to 1000 etc.
*/
printf("Enter two range(input integer numbers only):");
//Store the range in variables using scanf
scanf("%d %d", &num1, &num2);
//Display prime numbers for input range
printf("Prime numbers from %d and %d are:\n", num1, num2);
for(i=num1+1; i<num2; ++i)
{
flag_var=0;
for(j=2; j<=i/2; ++j)
{
if(i%j==0)
{
flag_var=1;
break;
}
}
if(flag_var==0)
printf("%d\n",i);
}
return 0;
}
Hello!
To solve this, we need to use some trigonometry. We will want to find the length of the bottom. To do so we will need to find those two sides.
First of all, let's find the base of the left triangle. Let's find the tangent of 45.
tan45=1
Therefore, 30/x=1. Just from this, we can see that the base of this triangle is 30.
Now for the other one. Here we have the hypotenuse. As we are looking for the adjacent side, we can use the cosine.
cos60=0.5
This gives us the equation x/80=0.5
From here, we can see that x=40.
Now we add our lengths.
30+40=70
Therefore, the length between the walls is 70 meters.
I hope this helps!
Answer:
15
Step-by-step explanation:
5a-10b=45, b=3
- 5a-10*3=45
- 5a= 45+30
- 5a= 75
- a= 75/5
- a=15
