Since it arrived at a zoo, a rhinoceros's weight has increased from 1 1/4 tons to 2 1/4 tons. By what percent has the rhinoceros's weight increased?
Answer:
80 percent increase in weight
Step-by-step explanation:
(2 1/4 - 1 1/4)/ 1 1/4 = 1/ (1 1/4) = .8 80 % increase
The combined area of a square and a rectangle is 225 square yards. the length of the rectangle is 8 times the width of the rectangle and the length of a side of the square is the same as the width of the rectangle. find the dimensions of the square and the rectangle.
Answer:
The rectangle: L = 40 yards. W = 5 yards
The square: The length and width are both 5 yards.
Step-by-step explanation:
Let L and W be the length and width of the rectangle.
Let l and w be the length and width of the square.
Area for each is:
Rectangle: L*W
Square: l*w
We are told that L*W + l*w = 225 yards^2
We are also told that
L = 8W
and that
l = W
Since the sides of a square are all equal, w is also W: w=W
Summarizing and substituting:
L*W + l*w = 225 yards^2
(8W)*W + W*W = 225 yards^2
8W^2 + W^2 = 225 yards^2
9W^2 = 225 yards^2
W^2 = 25
W = 5 feet
---------------------
Therefore, since L = 8W , L = 40 yards. W = 5 yards for the rectangle.
The square: l=W, so l = 5 yards, and thus w=5 yards
--------------------------
Check:
Do a rectangle of 40' x 5' plus a square of 5' x 5' have a total combined area of 225 yards^2?
40yd x 5yd + 5yd x 5yd = 225 yards^2?
200 yd^2 + 25 yd^2 = 225 yards^2?

What is the balance of the savings account?
Net worth is total assets less liabilities. Assets are items owned by a person that creates benefits in the future to the person. Liabilities are what are owed to another person.
Net worth = assets - liabilities
6760 = (2540 + 6000 + savings) - (880 + 1500)
6760 = 8540 + savings - 2380
Savings = 6760 - 8540 + 2380

Joe wants to make a epecial cleaning mixturefor his hardwood floors. He needs 3/4 cup of vinegar,2/4cup of clorox and 1/4 cups of water. How much cleaner does Joe have when he is finished makeing the mixture?
Answer: 1 1/2.
Step-by-step explanation: Joe is using 3/4 cup of vinegar, 2/4 cup of Clorox, and 1/4 cup of water to make a special cleaning mixture right? He's going to mix all of those ingredients together, which means that this is an addition problem. When we add 3/4, 2/4, and 1/4 cups, we add the numerators to get our answer:
3/4 + 2/4 + 1/4 = 6/4, or 1 2/4, or 1 1/2 cups of cleaner in total when we simplify.
Therefore, the total amount of cleaner he makes is 1 1/2 cups.
Let me know if this is right! :)
Study the following chemical equation. Identify the total number of atoms before and after the reaction. N₂ + 3H₂ → 2NH3
Before reaction, total number of nitrogen atoms is 2, also the total hydrogen atoms is 6. After the reaction, still, we have the same number of nitrogen atoms as 2, and hydrogen atoms as 6. This therefore obeys the law of conservation of mass that during a chemical reaction, matter is neither created nor destroyed.

what is the answer to this equation 4x + 5y =6
Answer:
Step-by-step explanation:
This equation has no solution. You have one equation with two variables, so it cannot be solved. If you have another equation having the same variables x and y, then by using simultaneous equations, values of x and y can be solved. But to this equation 4x + 5y = 6, there is no solution for the reason mentioned above.

What is the area of the semicircle (use 3.14 for p)?
Please help! Will mark brainlyest.
Answer:
127.17 cm²
Step-by-step explanation:
Area of a semicircle: 1/2*π*r²π (pi) = 3.14r (radius) = d (diamater) / 2 => 18/2 = 9 cmA = 1/2*π*r²
A = 1/2*3.14*9²
A = 1/2*3.14*81
A = 3.14*40.5
A = 127.17 cm²
Therefore, the area of the semicircle is 127.17 cm²
Hope this helps!
Answer: the first option: 127.17cm2
Step-by-step explanation:
1. divide the diameter in half to get the radius.
2. multiply the radius squared by pie
3. divide that answer in half
so:
9*9=81
81*3.14= 254.34
254.34/2= 127.17

what distance is travelled by a bus that travels at 105kph in 5 hours
Answer:
21mph = 33.80 km/h
Step-by-step explanation:
Speed = Distance / Time = 105 kph / 5 hours = 21 mph = 33.80 km/h
What is the distance traveled by the bus at a speed of 105 kph in 5 hours?
Answer:The distance traveled by the bus is 525 kilometers.
Step-by-step explanation:As per the provided information in the given question, we know that the speed is given by 105 kph. The time is given by 5 hours. In this problem, we are tasked to find the distance traveled by the bus.
To do this, we will use the formula below:
[tex]\large\begin{aligned}\bigstar\:\boxed{\rm{\: Distance = Speed \times Time \:}} \end{aligned}[/tex]
Substitute the given values into the formula given above and solve for Distance:
[tex]\large\begin{aligned}\rm:\implies{Distance}& = \rm{Speed \times Time} \\\rm:\implies{Distance} & =\rm{105\: kph \times 5\: hrs} \\\rm:\implies{Distance} & =\rm{525\: km} \end{aligned}[/tex]

Show that KLPQ is a parallelogram
for m = 14 and n = 12. 5. .
L
(5m + 36)
P
(6n – 1)º
(4m + 50)
K
Step-by-step explanation:
m = 14, n = 12.5
m<L = (5m + 36)° = (5(14) + 36)°
L = 106°
m<p= (6n-1°)=(6x12.5-1°)
p=74°
m<Q = (4m + 50)° = (4(14) + 50)°
Q = 106°
k=360°-(106°+74+°106°)=360°-286°
k=74°
The sum of the interior angle of a parallelogram is 360°
The opposite side of a parallelogram are equal.
You are forming words in which the first letter is either P, B, or M; the second letter is either A or E; and the third letter is either N or T. If each possible word is written on a slip of paper and you choose one slip at random, what is the probability that the second letter is an A?
Using it's concept, it is found that there is a 0.5 = 50% probability that the second letter is an A.
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
In this problem, we consider that:
For the first letter, there are 3 outcomes.For the second letter, there are 2 outcomesFor the third letter, there are 2 outcomes.Hence, the total number of words is:
T = 3 x 2 x 2 = 12.
With the second letter being A, the number of words is:
D = 3 x 1 x 2 = 6.
Hence, the probability is given by:
p = 6/12 = 0.5.
