find the surface area of a square based pyramid with a side length of 5cm and a slant height of 5cm
Answers
Answer:
Step-by-step explanation:
The surface area of a square pyramid = 1/2 * slant height * base perimeter + area of base
The slant height is 5 cm
The base perimeter is 4 * 5 cm = 20 cm
The area of the base is 5 cm * 5 cm = 25 cm**2
Plugging into the formula the area =
1/2 * 5 cm * 20 cm + 25 cm**2 =
5 cm * 10 cm + 25 cm**2 =
50 cm**2 + 25 cm**2 = 75 cm**2

Explanation:
Area of square = s x s = 11 x 11 = 121 cm2
Area of triangle = 1/2 x b x h = 1/2 x 11 x 13.2 = 72.6 cm2
Area of 4 triangles = 72.6 x 4 = 290.4 cm2
Total surface area = 121 + 290.4 = 411.4 cm2
Check the following pair of linear equations is consistent or inconsistent
5x - 3y = 11, -10x + 6y = -22
Answers
Answer:
Consistent
Step-by-step explanation:
It was a solution.
So first you need to switch -3y with 11 first because the the formula is y=mx+c
So, 5x -11= 3y
Now make y as the subject: 3y= 5x-11
Now divide both of the numbers by 3 to make it y=mx+c
So, y=3/5x-11
y=1.67x-3.67
Now try the another one by yourself by using my steps and remember that when you are switching the side. suppose if 3=5x if I will switch the side for this it will move from positive to negative so it will be -5x=-3.
If you want to switch from negative to positive it will be 3=5x (this is just an example)
I hope you understood my explanation. Thank me later.

In another right angle triangle the hypotenuse is 53, and the one of the side lengths is
28. Please find the missing side length,
Answers
A is 28 (side.) And C (hypotenuse) is 53.
So, 28^2+B^2=58^2 (^2 is squared)
We dont know what the other side is, so we keep it “B.”
28 squared is 784. 53 squared is 2,809.
So now, we take away ^2 since it was already squared. 784+B^2=2,809
Now, we subtract 784 from both sides
784+B^2=2,809
-784 -784
B^2= 2,025
Then you do the opposite of squaring, you square root
45. the missing side is 45

Jimmy and Jennifer are selling pies for a school fundraiser. Customers can buy apple pies and blackberry pies. Jimmy sold 10
apple pies and 2 blackberry pies for a total of $80. Jennifer sold 10 apple pies and 3 blackberry pies for a total of $100. Find the
cost each of one apple pie and one blackberry pie.
Answers
Answer:
One apple pie is $4 and one blackberry pie is $20
Step-by-step explanation:
Create a system of equations where a is the cost of one apple pie and b is the cost of one blackberry pie:
10a + 2b = 80
10a + 3b = 100
Solve by elimination by multiplying the top equation by -1, then adding the equations together:
-10a - 2b = -80
10a + 3b = 100
Add these together:
b = 20
So, one blackberry pie is $20. Plug in 20 as b into one of the equations, and solve for a:
10a + 2b = 80
10a + 2(20) = 80
10a + 40 = 80
10a = 40
a = 4
So, one apple pie is $4.
One apple pie is $4 and one blackberry pie is $20
express 450 g as a percentage of 20 kg
Answers
Answer:
Step-by-step explanation:
convert either gram into kg or kg into gram
lets convert kg into g
1 kg=1000g
20kg=1000*24g
=20000g
450/20000*100%
450/200%
2.25%
first convert 450 g to kg = 0.45 kg
Now 0.45 kg as a. percentage of 20 kg = 0.45/20×100= 2.25%

A. Same distance and different direction
В. Same distance and same direction
C. Different distance and different direction
D. Different distance and same direction
plz help!!!!!
Answers
Answer: В. Same distance and same direction
Step-by-step explanation:
A translation is a rigid transformation that maps each point of the original figure to a new position by the same distance and in the same direction.
It does not change the size or shape of the image.
Thus the correct statement relates to translation is "Same distance and same direction"
Hence, the correct option is B.

(i) 0 cups = 0.275
(ii) 4 cups = 0.125
(iii) 8 cups = 0.025
Step-by-step explanation:
(a) The frequency and relative frequency table has been attached to this response.
i. The first column, labelled x, is the number of cups of coffee consumed per day.
ii. The second column, labelled f, is the number of people that consumed x cups of coffee per day. It is found by counting the number of occurrences (i.e frequency) of the numbers of the first column, x, in the given data.
For example, 0 in first column appears 11 times in the given data. Also, 5 in the first column appears 4 times in the given data.
iii. The third column, labelled r, is the relative relative frequency of the number of cups of coffee. It is calculated by dividing the frequency of the cups of coffee by the total number of people that consumed it. As shown on the table, it is calculated by dividing the each of the values on the second column by the sum of the values on that same column (second column).
For example, the relative frequency of 2 cups of coffee is given by:
r = 7 ÷ 40 = 0.175
Also, the relative frequency of 4 cups of coffee is given by;
r = 5 ÷ 40 = 0.125
(b) The probability (Pₓ) that a randomly selected person consumed x cups of coffee is given by;
Pₓ = frequency of x ÷ total frequency
This is also the relative frequency of x
Therefore,
(i) The probability (P₀) that a randomly selected person consumed 0 cups of coffee is given by;
the relative frequency of 0 = 0.275
(ii) The probability (P₄) that a randomly selected person consumed 4 cups of coffee is given by;
the relative frequency of 4 = 0.125
(iii) The probability (P₈) that a randomly selected person consumed 8 cups of coffee is given by;
the relative frequency of 8 = 0.025
