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

Answer:

72 mins

Step-by-step explanation:

The number of minutes Sam spent on exercising is 72 minutes. Therefore, option B is the correct answer.

Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.

The given function is y = -0.78x + 95

Let x be the number of minutes of television Sam watched each day and y the number of minutes she spent exercising.

Here, x=30

Substitute x=30 in the given function, we get

y = -0.78(30)+95

= -23.4+95

= 71.6

≈ 72 minutes

Therefore, option B is the correct answer.

Step-by-step explanation:

Giving the following information:

iTones charges $10 per month, and $1 per song.

Music Mine charges $7 per month and $1.50 per song.

To calculate the total cost for each option, we need to use the following formulas:

iTones:

Total cost= 10 + 1x

x= number of songs

Music Mine:

Total cost= 7 + 1.5x

x= number of songs

Answer:y=4x+2

Step-by-step explanation:m= rise and b=run rise /run when u look at the graph start at the pount to a count how many u rise to get to 2 then cout how many u run to get to 2 again so that would be y=4x+2.

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

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.

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.

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
