Answer:
700.39cm
Step-by-step explanation:
For a horizontal distance of 30cm, the drop is 1cm, now we need to get the drop for horizontal distance of 700 cm to maintain the same slope
Using the concept of cross multiplication
30cm=1 cm drop
700 cm=x
30x=700
X=700/30=70/3=23 ⅓
Utilizing pythagoras theorem, the length of pipe will be
L=√(23⅓)²+700²
L=700.38878092417 cm
Rounded off, the length is approximately 700.39 cm
Answer:
75 in²
Step-by-step explanation:
(see attached for reference)
recall that the formula for area of a circle is given by
Area = π r²
where
π = given to be 3
r = radius given as 5 in
simply substituting the values into the equation:
Area = π r²
= 3 x 5²
= 3 x 25
= 75 in²
Answer:
C (The lizards in aquarium A vary in length more than aquarium B.)
Answer:
x = -1
Step-by-step explanation:
Subtract 3 from both sides:
6x = 2x - 4
Subtract 2x from both sides:
4x = -4
Divide both sides by 4:
x = -1
(by the way, this is an equation, not an inequality - equations use =, inequalities use < > ≤ ≥)
Answer:
2 out of every 5; 2:3; 2:5
Step-by-step explanation:
2 out of every 5 means that out of 5, he/she picks two (leftover 3)
the other choices are a ratio of if he/she has 2 of that then they will also have 5 of this
