hali invested money into an account that is guaranteed to grow$28 each year. she graphs a line that represents the growth of the account. with x representing the number of years since she first opened the account and y representing the number of dollars in it. what is the slope of the line?

Answers

Answer 1

if we take the graph with x as number of years and y as amount of dollars in it as mentioned in the equation;
gradient of the graph/ slope (m) = Change in y / change in x
so if we take a certain portion of the graph
x is the number of years, since we know the growth for one year,
lets take change in x as 1 year
y is amount of dollars, the change in amount of dollars for one year is 28
therefore change in y is 28
m(slope) = 28(change in y) / 1 (change in x)
= 28

Which equation represents the following word sentence? Five more than three times x is twenty. 5x + 3 = 20 3x + 5 +20 3(x + 5) = 20 3x + 5 = 20 Description

Answers

Final answer:

The equation that represents the word sentence 'Five more than three times x is twenty' is 3x + 5 = 20. To solve this equation, subtract 5 from both sides and divide both sides by 3 to find the value of x.

Explanation:

The equation that represents the word sentence 'Five more than three times x is twenty' is 3x + 5 = 20.

In this equation, '3x' represents three times x, and '5' represents five more than that. The equation states that the sum of three times x and five is equal to twenty.

To solve this equation, you can subtract 5 from both sides to isolate '3x', and then divide both sides by 3 to find the value of x.

A restaurant has 26 tables in its dining room. It takes the waitstaff 10 minutes to clear and set 4 tables. At this rate, how long will it take the waitstaff to clear and set all the tables in the dining room?

Answers

well, its 10 for 4. so 8 is 20, 12 is 30, 16 is 40 20 is 50, and 24 is 1 hour, 2 tabels is half the time so 5 min... so it would take -1 hour and 5 min

The time it will take the waitstaff to clear and set all the 26 tables in the dining room is;

1 hour 5 minutes

We are told that the waitstaff takes 10 minutes to clear and set 4 tables.

Thus, rate of clearing and setting 1 table = 10/4

rate of clearing and setting 1 table = 2.5 minutes per table

Now, we want to find out how long it will take her to clear and set 26 tables at the rate we got above.

By use of proportions, we can find it as;

Time it takes to clear and set 26 tables = 2.5 × 26

Time it takes to clear and set 26 tables = 65 minutes

We know that 60 minutes make 1 hour, thus converting the time to hour and minute gives us;

1 hour 5 minutes

For this case what you should see is the behavior of each function to find the correct answer.
We have functions of the type:
f (t) = a * (b) ^ t
Thus,
For I, we have:
f (t) = 30 * (1.05) ^ t
For V we have:
f (t) = 30 * (0.95) ^ t
For VI we have:
f (t) = 30 * (0.85) ^ t
Answer:
option c.

Answer:

Option: c is the correct answer.

c. φ, ε and δ

Step-by-step explanation:

From the graph given to us we see that the graph passes through the same initial point that is the starting point is same i.e. when t=0.

Also, they attain the maximum value at t=0.

α: [tex]10(1.2)^t[/tex]

Now when t=0 we have:

Value=10

β : [tex]10(1.5)^t[/tex]

Now when t=0 we have:

Value=10

χ: [tex]20(1.2)^t[/tex]

Now when t=0 we have:

Value=10

δ: [tex]30(0.85)^t[/tex]

Now when t=0 we have:

Value=30

ε: [tex]30(0.95)^t[/tex]

Now when t=0 we have:

Value=30

φ: [tex]30(1.05)^t[/tex]

Now when t=0 we have:

Value=30

Hence, we see that δ , ε and φ are the three functions such that they have the same initial value.

Juan lives 2.5 miles from the park. It took him 12 minutes to ride his bicycle to the park. What was Juan’s average speed in miles per hour?

Answers

2.5/12 = x/60

12x = 150

x = 12.5 mph

Juan's average speed was found to be 12.5 mph, calculated by dividing the distance of 2.5 miles by the time of 0.2 hours.

Juan lives 2.5 miles from the park, and it took him 12 minutes to ride his bicycle there. To find Juan's average speed in miles per hour, we need to follow a few steps. First, we convert the time taken into hours because speed is often expressed in miles per hour (mph).

12 minutes is equal to 12 / 60 hours, which is 0.2 hours. Then, we use the formula for average speed:

Average speed = Total distance / Total time

So for Juan's trip, we get:

Average speed = 2.5 miles / 0.2 hours = 12.5 mph.

Therefore, Juan's average speed was 12.5 mph.

Subtract the $10 from the amount of money Aliyah had to spend because we already know that she will NOT use the $10 towards the pencils.

24 - 10 = 14

This is how much money Aliyah spent on seven pencils. Now, we must find the cost of each individual pencil.

Next, divide this by the amount of pencils Aliyah bought (7):

Kim paycheck was $257.20. She put 1/4 of her paycheck into a savings account and used 1/3 of what was left to pay bills. How much money does she have remaining from her paycheck

Answers

To determine how much of her paycheck she put into her savings account, divide the total amount by 4:

257.2 / 4 = 64.3

A fourth of Kim's paycheck is $64.30; this is the amount she put into her savings account.

Since Kim now has 1/3 of her paycheck, we know that the 1/3 of what was left which she used to pay bills is equal to the amount she put into her savings account: $64.30.

Now, since we know that Kim had took out two equal amounts of money from her paycheck which were fourths, we know that whatever she has left will be half of that:

257.2 / 2 = 128.6

Answer:
Sue has $128.60 remaining from her paycheck.

What is the exact surface area of this right cone

A.1944 pi cm sq
B.5346 pi cm sq
C.1701 pi cm sq
D. 1215 pi cm sq

Answers

The correct answer is: [A]:  " 1944 pi cm sq" .
______________________________________________________
The exact surface area of the given "right cylinder" is:  " 1,944 π cm² " .
_______________________________________________________

Explanation:
______________________________________________________
The formula for the "surface area, S.A." of a right cone is:
______________________________________________________
→ S. A. = π r [ r + √(h² + r²) ]
______________________________________________________
in which: "S. A." is the "surface area" (in units of "cm² " ; in our case) ;
  → for which we shall solve;

  π = π ; (Note, we are asked to solve for the EXACT surface area of the given "right cone" ; so we shall solve in terms of "π" ; & we note that the answer choices provided are all "in terms of π" ;

" r = "radius" of the [circular base] = diameter / 2 ;

= 54 cm / 2 = 27 cm ;

" h = perpendicular height = 36 cm " ;
____________________________________________________

→ Plug in our known values into the formula/equation ;
for the "surface area, S.A." of a right cone to solve:
____________________________________________________

   → S. A. = π r [ r + √(h² + r²) ] ;

→ S.A. = π * (27 cm) * [ 27 cm + √[ (36 cm)² + (27 cm)² ] ;

= π * (27 cm) * [ 27 cm + √[ (36² * cm²) + (27² cm²) ] ;

= π * (27 cm) * [ 27 cm + √[ (1296 cm²) + (729 cm²) ] ;

= π * (27 cm) * [ 27 cm + √ [ (1296 + 729) cm² ] ;

= π * (27 cm) * [ 27 cm + √ [ (1296 + 729) cm² ] ;

= π * (27 cm) * [ 27 cm + √ [ (1296 + 729) cm² ] ;

= π * (27 cm) * [ 27 cm + √ (2025 cm² ] ;

= π * (27 cm) * [ 27 cm + √ (2025 cm² ] ;

= π * (27 cm) * [ 27 cm + 45 cm ] ;

= π * (27 cm) * [ 27 cm + 45 cm ] ;

= π * (27 cm) * [ 72 cm ] ;

= π * (27 cm) * [ 72 cm ] ;

= (27 * 72) * π cm² ;

= (27 * 72) * π cm² ;

= " 1,944 π cm² " .

A restaurant buys a freezer in the shape of a rectangular prism. The dimensions of the freezer are shown. What is the volume of the freezer?

Dimensions- 36 in, 24 1/2 in, 72 1/2 in.

Please explain clearly how you got your answer

Answers

To answer this question you will use the formula for finding volume of a rectangular prism. V=lwh, where V stands for volume, l stands for the length, w stands for the width, and h stands for the height. What you are really doing is finding the area of the base of the rectangular prism by multiplying the length by the width. Once you have this you then multiply it by the height which takes you all the way through the prism to create the third dimension of volume. The answer is 63,945 cubic inches.
