Last week John’s hamster drank 45 mL of water. This week he drank 25 mL of water. By what percent did the hamster’s intake of water decreased?
Answers
Answer:
Percentage decrease is 55%.
Step-by-step explanation:
Given the following data;
Original (old) number = 45mL
New number = 20mL
[tex] Percentage \; decrease = \frac{change\; in \;amount}{original\;number} * 100[/tex]
Change in amount = 45 - 20 = 25
Substituting into the equation, we have;
[tex] Percentage \; decrease = \frac{25}{45} * 100[/tex]
[tex] Percentage \; decrease = 0.55 * 100[/tex]
[tex] Percentage \; decrease = 55%[/tex]
Therefore, the hamster’s intake of water decreased by 55%.

10. Six cases of paper cost $159.98. How much does one
case cost? explain
HELP!!!
Answers
Answer:
$26.6633333333
Step-by-step explanation:
You divide $159.98 by 6 lol
$26.66 per case
Explanation:
We want to find the cost per case. Therefore we must divide the cost by the number of cases.
cost per case= cost/cases
We know that it costs $159.98 for 6 cases of paper.
cost per case= $159.98/6 cases
Divide.
cost per case= $26.66333333333333/case
Round to the nearest cent or hundredth. The 3 in the thousandth place tells us to leave the 6 in the hundredth place.
cost per case ≈$26.66
It costs about $26.66 per case of paper.

Samir begins riding his bike at a rate of 6 miles per hour. Twelve minutes later, Chris leaves from the same point and bikes along the same route at 9 miles per hour. How long after Chris begins riding does he catch up to Samir? 4 min 12 min 24 min 40 min
Answers
Answer:
The correct option is C) 24 min.
Step-by-step explanation:
It is given that:
Speed of Samir riding his bike = 6mph
Speed of Chris riding his bike = 9 mph
Let the time taken by Chris be x min. Then the time was taken by Samir be x+12
We know that the formula for the distance is
Where d is the distance, t is the time and r is the rate.
According to the question:
[tex]9x=6(x+12)\\9x=6x+72\\9x-6x=72\\3x=72\\x=24[/tex]
Hence, after 24 minutes Chris will catch up to Samir.
Therefore the correct option is C) 24 min.

Step-by-step explanation:
Step 1: Write equation
15 - 5(4c - 7) = 50
Step 2: Solve for c
Distribute -5: 15 - 20c + 35 = 50Combine like terms: -20c + 50 = 50Subtract 50 on both sides: -20c = 0Divide both sides by -20: c = 0Step 3: Check
Plug in c to verify it's a solution.
15 - 5(4(0) - 7) = 50
15 - 5(-7) = 50
15 + 35 = 50
50 = 50
15 - 20c + 35 = 50
50 - 20c = 50
-20c = 0

Working together ,Ann and Jane painted a total of 480 square feet in 3 hours they each painted the same num of sq feet what is the average rate that ann and Jane each painted in square feet per hour
Answers
The average rate that Ann and Jane each painted is 80 square feet per hour.
What is rate of change?A rate of change is a rate that describes how one quantity changes in relation to another quantity.
Now it is given that,
Total area painted by Ann and Jane = 480 square feet
Time taken in painting 480 square feet = 3 hours
Now let x and y be the amount painted by Ann and Jane.
Since,they each painted the same number of sq feet
⇒ x = y
Therefore, Total area painted = x + y = 2x
or, 2x = 480 square feet
⇒ x = 240 square feet
So, the same num of sq feet painted by both is 240 sq feet each
Now average rate = num of sq feet painted by each/time taken
⇒ average rate = 240/3 square feet per hour
or, average rate = 80 square feet per hour
Thus, The average rate that Ann and Jane each painted is 80 square feet per hour.

Answer:
x = 21
Step-by-step explanation:
By the corresponding angle theorem, we can find that the measure of the smaller angle made by transversal and m is 54°.
Using the vertical angle theorem, we can find that the missing angle is the triangle, the two known angles are 4x and 2x, is also 54°.
Since the sum of the interior angles of a triangle is always equal to 180°, we can make the equation:
2x + 4x + 54 = 180
Now we solve for x. Subtract 54 from both sides and combine like terms.
6x = 126
Divide both sides by 6.
x = 21
and now we have found the value of x. x = 21.
I hope you find my answer and explanation to be helpful. Happy studying.
Answer:
x=21°
Step-by-step explanation:
Relations Between Angles
We need to recall two basic relations:
* Two angles opposite by crossing lines are always equal.
* The sum of angles in a triangle is 180°
We'll add some variables to the image, so x is easier found. Please check the image below.
The angles U and 54° are opposite and they must be equal, thus U=54°
Since m and n are parallel and they are crossed by a line, the angles V and U are equal, thus V=54°
Finally, The sum of the angles inside the triangle RST must be equal to 180°:
2x+4x+54=180
Joining like terms:
6x=180-54=126
Solving:
x=126/6
x=21°
