Answer:
41 units
Step-by-step explanation:
Rectangles have right angles, so we can use Pythagorean theorem to find the diagonal.
c² = a² + b²
c² = 9² + 40²
c² = 81 + 1600
c² = 1681
c = 41
X=is the number looked for.
x/2=is the half of "x".
x/3=is the one-third of the "x".
We suggest this equation:
x+(x/2)+(x/3)=22
Least common multiple=6
6x+3x+2x=132
11x=132
x=132/11=12
Te number is 12
To check:
A number (12)+ half of that number (6)+ the one-htird of that number(4) is:22
12+6+4=22
Answer:
$345 : whichever is closest
Step-by-step explanation:
Pants were $20 each and she bought 9 of them so multiply:
9x20=180
She paid $180 for 9 pants.
Shirts cost $15 each and she bought 11 of them so Mulitply:
15x11=165
She paid $165 for 11 shirts
Add both totals from pants and shirts
165+180=$345
Mathematics and science go hand in hand. The branches of science which include: Physics, astronomy, chemistry, biology, etc. In all these fields you will find that you will have to use the mathematical principles and formulae to solve the numerical problems. So, science needs maths but maths does not need science.
