Bonus Problem 2. A pump fills an empty pool at a rate of 500 cubic meters per hour. If one liter is equivalent to one cubic decimeter and 1 meter is equal to 10 decimeters, how many liters of water are in the pool half an hour after the pump starts?
Guys im begging you this is why i joined brainly :C
I'll mark brainliest I promise
Answer:
250,000 L
Step-by-step explanation:
we are given the fill rate of 500 m³ per hour , i.e.
in 1 hour ------> 500 m³ would have been added
if the fill rate is constant, then it reasons that in 1/2 hour, we would expect to see only 1/2 volume of water compared to a full hour , hence:
in 1/2 hour ------> 1/2 x 500 m³ = 250m³ would have been added
The question wants the answer in liters, however we have just calculated the volume in m³ above. Hence we need to convert 250m³ into liters
We note that 1 m³
= 1 m x 1 m x 1 m ( we are given that 1 meter is equal to 10 decimeters. substitute this into the equation,)
= 10 dm x 10 dm x 10 dm
= 1000 dm³
therefore 250m³ = 250 m³ x 1000 dm³ per m³= 250,000 dm³
we are further given that:
1 dm³ = 1 L, hence
250,000 dm³ = 250,000L
Answer:
Answer:
250,000 L
Step-by-step explanation:
As infants grow from a toddler to a young adult, there may be times when they are ill and medication is needed. It is extremely important that medication be administered in the exact dose so the child receives the correct amount. Too little or too much medication could have serious side effects. A popular children’s fever medicine manufacturer recommends the following dosage information to parents and pediatricians.
Children’s Fever Medicine
(given every 4–6 hours, as needed)
Weight
24+ lbs
36+ lbs
48+ lbs
60+ lbs
72+ lbs
Dosage
5 mL
7.5 mL
10 mL
12.5 mL
15 mL
a) Evaluate the data and find the rate of change from one age group to the next. Explain how you found the rate of change. (2 points)
b) Is the relationship between weight and the amount of medicine linear? Explain
Answer:
Every weight range goes up 2.5mL
24+=5mL
+2.5 in the 36+=7.5mL
I am not sure the second answer
Step-by-step explanation:
Using function concepts, it is found that:
a) The rate of change is of 0.2083 ml/lb.
b) Since the rate of change is constant, the function is linear.
Item a:
The input is the weight.The output is the dosage.The rate of change is given by the change in the output divided by the change in the input.From the table, when the weight changes by 12 lbs, the dosage changes by 2.5 mL, hence:
[tex]r = \frac{2.5}{12} = 0.2083[/tex]
The rate of change is of 0.2083 ml/lb.
Item b:
Linear functions have constant rate of change, hence, since the rate of change is constant(0.2083 ml/lb), the function is linear.

Roberto Clemente, born in Puerto Rico, became the first Latino baseball player to be inducted in the National Baseball Hall of Fame in 1973. He held many records including reaching 3,000 career hits. During that game, the umpire briefly stopped the game to give the ball to Clemente, who tossed it from second base to the first base coach. If the first base coach was standing 3 feet behind first base and Clemente was standing on second base, which is 90 feet from first base, which expression describes the distance between Clemente and the first base coach?

Step-by-step explanation:

Have a nice day :]
The equation in vertex form is [tex]y = (x + 3)^2 + 1[/tex], and the values of h & k are -3 and 1
What is the vertex form?The vertex form of an equation is a quadratic equation, written in the form of a parabola
The equation is given as:
[tex]y = x^2 + 6x + 10[/tex]
Write out the constant
[tex]y = (x^2 + 6x) + 10[/tex]
Take the coefficient of x
[tex]k = 6[/tex]
Divide by 2
[tex]k/2 = 3[/tex]
Square the expression
[tex](k/2)^2 = 9[/tex]
So, we have:
[tex]y = (x^2 + 6x + 9 - 9) + 10[/tex]
Rewrite as:
[tex]y = (x^2 + 6x + 9) -9+ 10[/tex]
[tex]y = (x^2 + 6x + 9) + 1[/tex]
Express as a perfect square
[tex]y = (x + 3)^2 + 1[/tex]
Hence, the equation in vertex form is [tex]y = (x + 3)^2 + 1[/tex], and the values of h & k are -3 and 1

Explain why when you reflect a point across the line y=x, the x−coordinate and the y−coordinate change places, and when you reflect a point across the line y = −x, the x−coordinate and the y−coordinate change places and their signs are changed.
Answer:
The (x,y) is like a mirror reflecting across the plane. When it moves it goes opposite (y,x). We move over the y axis and we get a negitive because of the negative cordinate plane.

The Bernards are trying to determine their babysitter's rates but are to embarrassed to just ask her. They were charged $20 for 2 hours last week, but only $31 for 4 hours this week. What is the formula to determine A(Amount) given t(time in hours)?
Answer:
A = 5.5t + 9
Step-by-step explanation:
We assume that the relationship between t and A is linear.
We have two points on a line: (2, 20) and (4, 31).
We now find the equation of the line.
A = mt + b
m = (31 - 20)/(4 - 2) = 11/2 = 5.5
20 = 5.5(2) + b
20 = 11 + b
b = 9
A = 5.5t + 9
Which angle measures are correct? Select three options. mAngle2 = 125° mAngle3 = 55° mAngle8= 55° mAngle12 = 100° mAngle14 = 100°
Answer:
m<2 = 125°, m<8 = 55° and m<14 = 100°
Step-by-step explanation:
The question is incomplete.
Lines e and f are parallel. The mAngle9 = 80° and mAngle5 = 55°. Parallel lines e and f are cut by transversal c and d. All angles are described clockwise, from uppercase left. Where lines e and c intersect, the angles are: 1, 2, 4, 3. Where lines f and c intersect, the angles are 5, 6, 8, 7. Where lines e and d intersect, the angles are 9, 10, 12, 11. Where lines f and d intersect, the angles are 13, 14, 16, 15. Which angle measures are correct? Select three options. mAngle2 = 125° mAngle3 = 55° mAngle8= 55° mAngle12 = 100° mAngle14 = 100
Given
m<9 = 80°
m<5 = 55°
From the diagram, m<5+m<6 = 180°
Substitute m<5 = 55° into the formula, to get m<6
55+m<6 = 180
m<6 = 180-55
m<6 = 125°
From the diagram m<6 = m<2 = 125° (corresponding angles)
Also on line e, m<9 = m<12 = 80° (vertically opposite angles)
On line f, m<14+m<16 = 180° and m<12 = m<16 = 80
m<14+80° = 180°
m<14 = 180-80
m<14 = 100°
Also on line f, m<5 = m<8 (vertically opposite angles)
Since m<5 = 55°, m<8 = 55°
Also on line e, m<10 + m<12 = 180
Since m<2 = m<10 = 125° (corresponding angle)
To get m<12,
125+m<12 = 180
m<12 = 180-125
m<12 = 55°
Also m<10 = m<14 = 125° (corresponding angle)
On line e, m<10 = m<11 = 125° (vertically opposite angle)
Also on line e, m<3 = m<11 (corresponding angle)
This shows that m<10 = m<11 = m<3 = 125°
From the above calculation the angle measure that are correct are:
m<2 = 125°, m<8 = 55° and m<14 = 100°
