Answer:
The 1st answer, <em>The blue whale has about 200 times more mass. </em>might be correct.
Step-by-step explanation:
9 x 10 ^2= 900 kilograms
1.8 × 10 ^5= 180000 kilograms
180000 kilograms / 900 kilograms= 200 times
Answer:
The value of k is 5.
Step-by-step explanation:
Since we know we can convert function's quadratic form to vertex form by completing the square.
f(x)=x2?6x+14
We will add and subtract 9 to our equation in order to complete the square.
Upon completing the square and combining like terms we will get,
Upon comparing Willie's vertex form with our expression we can see that k is 5.
Therefore, the value of k is 5.
Let the number be x.
x*x*x = 54
x³ = 54 Taking cube roots
x = ∛54
x ≈ 3.780
Answer:
3 million barrels
Step-by-step explanation:
Total crude oil=60 million barrels
gasoline 34% diesel 29% total crude oil -60 million barrel · =0.34 times 60
Diesel=20,400,000 and gasoline=17,400,000
Quantity of gasoline = 34% of total crude oil
=0.34 times 60 =20.4
Quantity of diesel = 29% of total crude oil
=0.29 times 60 { million barrels}
Clearly, Quantity of gasoline is more than Quantity of diesel
difference = Quantity of gasoline-Quantity of diesel
20.4 -17.4 milion barrels
Therefore,
The production of gasoline is 3 million barrels more than diesel last year.
Answer:
2 hours
Step-by-step explanation:
given that the calorie burn rates are:
swimming: 400 cal / hour
rollerblading: 600 cal / hour
If he swims for 3 hours, he will burn:
400 cal / hour x 3 hours
= 1200 cal
Since his goal is 2400 calories, the number of calories that he has left to burn after swimming is:
2400 - 1200
= 1200 calories.
Number of hours of rollerblading to burn 1200 calories
= 1200 calories ÷ 600 calories per hour
= 2 hours
