Answer:
132 square units
Step-by-step explanation:
We are to find the surface area of a square pyramid.
From the diagram above, we are given:
Slant height = 6 units
Base = 8 units
The formula is given as:
= 2bs + b²
= 2 × 8 × 6 + 6²
= 96 + 36
= 132 square units
Can someone find the surface area
Answer:
front triangle: (6x4)/2 = 12
back triangle: (6x4)/2 = 12
side: 12x5 = 60
other side: 12x5 = 60
bottom: 12x6 = 72
12 + 12 + 60 + 60 + 72 = 216

A person's height is 5-ft 3-in. Their shadow has a length of 3-ft 6-in. If a nearby tree has a shadow of length 10-ft 4-in, what is the approximate height of the tree?
Answer: The height of tree = 15 ft. 6 inches
Step-by-step explanation:
Given: A person's height is 5-ft 3-in = [5 x (12 )+3 ] inches [ 1 ft= 12 inches]
= 63 inches
Their shadow has a length of 3-ft 6-in = [3 x 12+6] inches
= 42 inches
If a nearby tree has a shadow of length 10-ft 4-in = [10 x 12+4] inches
= 124 inches.
At the same time,
[tex]\dfrac{\text{Height of tree}}{\text{Height of person}}=\dfrac{\text{Length person's shadow}}{\text{Length of tree's shadow}}\\\\\dfrac{\text{Height of tree}}{63}=\dfrac{124}{42}\\\\\Rightarrow\ \text{Height of tree}=\dfrac{124}{42}\times63=186\ inches\\\\=\dfrac{186}{12}= 15.5 ft\ or\ 15 ft.\ 6\ inches.[/tex]
Hence, the height of tree = 15 ft. 6 inches

The eight-digit number ppppqqqq, where p and q are digits, is a multiple
of 45. What are the possible values of the eight-digit number? multiples
Answer:
There are two possible numbers: 99 990 000 and 44 445 555
Step-by-step explanation:
The multiples of 45 are 5 and 9
There are two possible numbers: 99 990 000 and 44 445 555.
What will be the two numbers?
Numbers are the numerical values like 1,2,3 etc.It is given that The eight-digit number ppppqqqq, where p and q are digits, is a multiple of 45.
Every multiple of 45 is a multiple of both 5 and 9 here P and Q are single-digit integers.
By using the rules of divisibility we can see that if q=0 or q =5 so 4P+4q is a multiple of 9.
If q=0 4P is a multiple of 9 P=9
If q =5 ( 4p + 5 ) is a multiple of 9
Hence p + 5 = 9 and p =4
Therefore there are two possible numbers: 99 990 000 and 44 445 555.

The mean age of 5 people in a room is 39 years.
A person enters the room.
The mean age is now 36.
What is the age of the person who entered the room?
Answer:
fast multiply 5 by 39 to get the total age of the five people now as you are told those per 5 so imagine the six person being you if you enter you're going to add to their ages so they mean is going to be for six people so take the six people x their mean age now we have two different total ages for the five people and for the six people subtract the total age of the 5 from the 6th total ages to get the age of the person who entered the room if you don't understand please ask me and be willing to help
Answer:
The age of the person who entered the room is 21.
Step-by-step explanation:
Mean of 5 peoples = 39
i.e.
Sum / 5 = 39
Sum = 39 x 5
Sum = 195
Mean after one person enters the room = 36
Let x be the age of the new person.
Then
Mean = (Sum + x)/ 6
36 = (195 + x)/6
36 x 6 = 195 + x
216 = 195 + x
x = 216 - 195
x = 21

Find the area of each shaded region in each figure.
Answer:
Step-by-step explanation:
Area of Yellow Rectangle
Area = L * W
Area = 25 * 11
Area = 275
Area of Parallelogram
Area = Base * height
Area = 12 * 4
Area = 48
Area of shaded area
Area = rectangle - Parallelogram
Area = 275 - 48 = 227 square feet
