Rectangle divided into four rectangles. The perimeters of rectangle #1, #2, #3, #4 are 10 cm, 20 cm, 28 cm and 18 cm respectively. Find the perimeter of the big rectangle.
Answer:
Perimeter of big rectangle = 38 units
Step-by-step explanation:
Let the sides of rectangle (1) = a and c cm
Sides of rectangle (2) = b and c cm
Sides of rectangle (3) = b and d cm
Sides of rectangle (4) = a and d cm
Perimeter of (1) = 2(length + width)
2(a + c) = 10
a + c = 5 ---------(1)
Perimeter of (2) = 2(b + c)
2(b + c) = 20
b + c = 10 -------(2)
Perimeter of (3) =2(b + d)
2(b + d) = 28
b + d = 14 --------(3)
Perimeter of (4) = 2(a + d)
2(a + d) = 18
a + d = 9 -------(4)
Since perimeter of the big rectangle = 2(a + b + c + d)
By adding equations (1) + (2) + (3) + (4),
(a + c) + (b + c) + (b + d) + (a + d) = 5 + 10 + 14 + 9
2(a + b + c + d) = 38
Therefore, perimeter of the rectangle ABCD = 38 units

In 1000 sq. meter of land a farmer cultivated 765 kg of rice with the wastage of 23.5%.I) Find the weight of the wastage. II) Find the weight and percentage of rice cultivated.
Answer:
i. weight of wastage(kg) = 179.775 kg
ii. weight of rice cultivated = 765 kg - 179. 775 kg = 585.225 kg
percentage of rice cultivated = 100 - 23.5 = 76.5%
Step-by-step explanation:
A land of 1000 sq. meter is used to cultivate 765 kg of rice with wastage of 23.5%.
i. The wastage in percentage is 23.5% but the weight of the wastage in weight is 23.5% of 765 kg
weight of wastage = 23.5/100 × 765
weight of wastage = 17977.5/100
weight of wastage(kg) = 179.775 kg
ii. weight and percentage of rice cultivated.
weight of rice cultivated = 765 kg - 179. 775 kg = 585.225 kg
percentage of rice cultivated = 100 - 23.5 = 76.5%

if U is the midpoint of CB, CU=18, and CB= 2x-10, then find x
Answer:
x = 23
Step-by-step explanation:
CU + UB = CB
Since U is the midpoint that means CU = UB = 18
18+ 18 = 2x-10
36 = 2x-10
Add 10 to each side
36+10 = 2x
46 =2x
Divide by 2
23 = x
Answer:
x = 23Step-by-step explanation:
CB/2 = CU
CB = (2)CU
2x - 10 = (2)18
2x - 10 = 36
Add 10 on both sides.
2x = 46
Divide both sides by 2.
x = 23

There are d black and brown horses in a field. There are 16 more black horses than brown horses. Of the horses in the field, only 25% of them are brown. How many are black?
Answer: 24 black horses
Step-by-step explanation:
Let the number of black horses = bl and
The number of Brown horses = br
Total number of horses = d
Of the horses in the field, only 25% of them are brown. That is,
25% of d = br
0.25d = br ........ (1)
The remaining horses are black. Which will be 100% - 25% = 75%. That is,
75% of d = bl
0.75d = bl ........(2)
But according to the question, there are 16 more black horses than brown horses. That is,
bl = br + 16 ..... (3)
The total number of horses d will be
d = br + bl ...... (4)
Substitute bl in equation 3 into equation 4
d = br + br + 16
d = 2br + 16 ..... (5)
Substitutes equation (1) into the equation (5)
d = 2( 0.25d ) + 16
d = 0.5d + 16
Collect the like terms
d - 0.5d = 16
0.5d = 16
d = 16/0.5
d = 32
Substitute 32 for d in equation (2).
bl = 0.75 × 32
bl = 24 horses.
Therefore, 24 horses are black.

21. In 1960, the average speed of passenger
aircraft within the U.S. was 235 miles per
hour. By 1978 the average speed was 1.74
times that amount. To the nearest whole
number, what was the average speed in 1978?
Help mepleaee
Answer:
Average speed of passenger aircraft in 1978 is 408.9 mph
Step-by-step explanation:
Here, in the question, we are tasked with giving the value of the average speed of the passenger aircraft in the US for the year 1978, given that it is a certain multiple of the value in 1960.
So what we will be doing here is to get the value of the average speed and it can be gotten by multiplying the average speed in 1960 by the multiple to which the speed is, now in 1978.
From the question, we can write a formula for this;
Average speed of passenger aircraft in 1978 = 1.74 * average speed of passenger aircraft in 1960
From the question, we have that the average speed of passenger aircraft in 1960 = 235 mph
Thus,
Average speed of passenger aircraft in 1978 = 1.74 * 235 = 408.9 mph
Identify the Minimum value of the function y=x^2+6x+ 9
====================================================
Explanation:
You can factor x^2+6x+9 into (x+3)^2, which turns into 1(x - (-3) )^2 + 0
So y = x^2+6x+9 becomes y = 1(x - (-3) )^2 + 0
That matches with vertex form y = a(x-h)^2 + k
The vertex is (-3,0). The y coordinate of the vertex directly tells us the minimum value. We know we have a minimum because a = 1 is positive. If a < 0, then we'd have a max y value instead.
-------------------
Alternatively, compare y = x^2+6x+9 to the form y = ax^2+bx+c
We see that a = 1, b = 6, c = 9
The x coordinate of the vertex is
h = -b/(2a)
h = -6/(2*1)
h = -3
The x coordinate of the vertex is x = -3. Plug this into the original equation to find the y coordinate of the vertex
y = x^2 + 6x + 9
y = (-3)^2 + 6(-3) + 9
y = 9 - 18 + 9
y = -9 + 9
y = 0
The y coordinate of the vertex is y = 0. This is the smallest y output possible.
An empty container has a capacity of 60000 litres to 1 significant figure Tony pours in 5400 litres of water to 1 significant figure He says “I have filled more than 10% of the container” Is he correct
Answer:
The container's capacity could be anything from 55,000 to 65,000. Exactly 10% of that is anything from 5500 to 6500.
The amount of water poured in could be anything from 5350 or 5450. That is NOT in the range above, so the answer is NO.
No, Tony is not correct.
The following information should be considered:
The container capacity could be varied from 55,000 to 65,000. Now if do exactly 10% so it should be 5,500 to 6,000.But the amount of water poured could be 5,350 or 5,450.Based on the above information we can conclude that tony is not correct.

Answer:
See Explanation
Step-by-step explanation:
(a)For matrices A and D, given that: [tex]AD=I_m[/tex].
We want to show that [tex]\forall b \in R^m[/tex], Ax=b has a solution.
If Ax=b
Multiply both sides by D
[tex](Ax)D=b \times D\\\implies (AD)x=bD$ (Recall: AD=I_m)\\\implies I_mx=Db $ (Since I_m$ is the m\times m$ identity matrix)\\\implies x=Db[/tex]
This means that the system Ax=b has a solution.
(b)Matrix A has a pivot position in each row where each pivot is a different column. Therefore, A must have at least as many columns as rows.
This means A cannot have more rows than columns.

Hannah wants to display all the possible outcomes when rolling two fair 6-sided dice. By drawing a sample space, find the probability of the scores on the two dice adding to 11.
Answer:
1/18
Step-by-step explanation:
First list all the 2 answers that may add up to 11:
5 and 6
6 and 5
There are no more.
Next how many possible outcomes can se get?:
6 x 6 = 36
Thus, the probability = 2/36 = 1/18
The odds of the two dice's results adding up to 11 are 1/18.
What is probability?Probability is a number that expresses the likelihood or chance that a specific event will take place. Both proportions ranging from 0 to 1 and percentages ranging from 0% to 100% can be used to describe probabilities.
given, Hannah wants to display all the possible outcomes when rolling two fair 6-sided dice.
From the general formula of probability:
Probability = desired outcomes / total possible outcomes
in our case desired outcome = scores on the two dice adding to 11
the desired outcome is getting 6, 5 and 5,6
thus desired outcome = 2
since the dice is 6-sided
total outcome = 6*6 = 36
probability = 2/36
Probability = 1/18
therefore, the probability of the scores on the two dice adding to 11 is 1/18.
