Answer:
3159.853 km
Step-by-step explanation:
The question says a square has an area of 9,984,670 km^2, which means that all sides are the same length. So you can use the equation:
9984670 = (x)(x) which rearranges to 998470 = x^2
get the square root and you get:
x = 3159.853 km
Answer:
33.3% decrease or 33%
Step-by-step explanation: 1/3 of 18 is 6. 1/3=33.3% it moved down by six people so 33% is your answer
Answer:
Yes, the two ratios are proportional because they are the same ratio
Step-by-step explanation:
10/2=5
24/2=12
10/24=5/12
Answer:
1.5
Step-by-step explanation:
base x height x 0.5
Pythagorean theorem: c^2 - a^2 = b^2
b = square root of (2.5)^2 - (1.5)^2
= 2
b = height
area = 0.5 x 1.5 x 2 = 1.5
9u+39=6(u+2)
multiply 6 by u and 2
9u+39=6u+12
9u-6u=12-39
3u=-27
u=-27/3
u=-9
hope this helped :)
