Answer: 2.5
Step-by-step explanation:
y = rx
substitute numbers in and solve for r
if
y = 10
x = 4
then
10 = r4
r = 10/4 = 2.5
this works for all the other numbers and always gives r = 2.5
Answer:
The inequality that comes from this equation is -2 < x < 0
Step-by-step explanation:
In order to solve this equation, we need to start by solving for the absolute value portion of the equation.
-5l2x + 2l + 7 > -3
-5l2x + 2l > -10
l2x + 2l < 2
Now we need to split the equation into two different portions. One with the absolute value symbol taken away. Then we do it again with the symbol flipped and the answer negated.
2x + 2 < 2
2x < 0
x < 0
And the negated version.
2x + 2 > -2
2x > -4
x > -2
Answer:
91,000 Liters
Step-by-step explanation:
1 Kiloliters = 1,000 liters
91 times 1,000 = 91,000
Answer:
136 units²
Step-by-step explanation:
The surface area (SA) is calculated as
SA = area of base + area of 2 congruent sloping faces + area of 2 triangular ends
area of base = 6 × 7 = 42 units²
area of sloping faces = 2 (7 × 5) = 2 × 35 = 70 units²
area of triangular faces = 2 × 
× 6 × 4 = 6 × 4 = 24 units²
SA = 42 + 70 + 24 = 136 units²
<u>Answer</u>
1/6
<u>Explanation</u>
Probability is a chance of an event taking place.
Probability = (favorable outcome)/(total outcome)
There are 3 even sides in a dice.
P(even) = 3/6
= 1/2
There are 2 numbers that are greater than 4 in a dice.
P(x>4) = 2/6
= 1/3
P(even and x>4) = 1/2 × 1/3
= 1/6
