5t+t–2t

Answers

Answer:

4t

Step-by-step explanation:

Note that teach term has the variable t in it. Also, note that if t is by itself, it actually means 1t. Combine the given constants:

5t + 1t - 2t

= (5t + 1t) - 2t

= (6t) - 2t

= 4t

4t is your answer.

Answer:

  A.  9 cubic units

Step-by-step explanation:

We interpret the smudges in your attachment to be dimensions of 1 1/2, 4, and 1 1/2. The volume is the product of these.

  V = LWH

  V = (4)(1.5)(1.5) = 9 . . . . cubic units

Determine how many people will fit in a building with a width of 105 feet and a length of 250 feet, if we use a standard of 16 people per 25 square feet.

Answers

Answer:

16,800 people

Step-by-step explanation:

105 * 250 = 26,250

p = 26250ft² * (16 people / 25ft²)

p = 16,800 people

Answer:

16800

Step-by-step explanation:

105 x 250 = 26250 and then divide it by 25 which is 1050 then multiply by 16 which is 16800

How does the distance traveled and time elapsed compare for Carrie and Kevin as they traveled from mile marker 225 to mile marker 230?

Answers

Answer:

This implies that they traveled the same distance and they spend the same amount of time from 225 to 230 mile marker

Step-by-step explanation:

Given

See attachment for graph

Required

Compare the distance and time travel

From the attached graph, we have the origin to be (0,0).

This represents the mile marker 225

Mile marker 230 is represented by point 5 on the y-axis.

Kevin's line at point 5 is represented as: (16,5)

Carrie's curve at point 5 is represented as: (16,5)

Both points are equal; i.e.

[tex](16,5) =(16,5)[/tex]

This implies that they traveled the same distance and they spend the same amount of time from 225 to 230 mile marker

(t+5)(t+2),make t the subject of the formula​

Answers

Answer:

t= 2p+5/p-1

Step-by-step explanation:

The question is not well writen

Assume p = t+5/t-2

We are to make t the subject of the formula

Cross multiply

p(t-2) = t+5

pt - 2p = t+5

pt - t = 2p+5

t(p-1) = 2p+5

t= 2p+5/p-1

Hence the value of t is 2p+5/p-1

Length of Line AC = 26 units

Step-by-step explanation:

Given:

Line AC = [3x + 1] + 8

Line BC = [x - 2] + 2

Find:

Length of Line AC

Computation:

Line AB ║ Line L

So,

Using Mid-Point theorem;

[3x + 1] / 8 = [x - 2] / 2

2[3x + 1] = 8[x - 2]

6x + 2 = 8x - 16

8x - 6x = 16 + 2

2x = 18

x = 9

So,

Line AC = [3x + 1] + 8

Line AC = [3(9) + 1] + 8

Line AC = [27 + 1] + 8

Line AC = 28 + 8

Length of Line AC = 26 units

Find the slope on the line?

Answers

Answer:

slope=0

Step-by-step explanation:

Hi there!

We're given a graph with a line and two marked points on the graph: (-1,3) and (3,3)

the formula given for slope calculated from two points is (y2-y1)/(x2-x1), where (x1,y1) and (x2,y2) are points

we have our two points: (-1,3) and (3,3) and we can label them:

x1=-1

y1=3

x2=3

y2=3

now substitute into the formula

note: Remember the formula shows SUBTRACTION, even though we have NEGATIVE numbers. When we simplify, we'll add the numbers.

slope=(3-3)/(3--1)

simplify

slope=0/4

divide

slope=0

If the above cube is a container with an inside length of 25cm, how many

litres will it hold?

Answers

Answer:

Capacity of cube in liter = 15.625 liter

Step-by-step explanation:

Given:

Side of cube = 25 cm

Find:

Capacity of cube in liter

Computation:

Volume of cube = Side³

Volume of cube = 25³

Volume of cube = 15,625 cm³

We know that

1 cm³ = 0.001 liter

Capacity of cube in liter = Volume of cube in cubic cm x 0.001

So,

Capacity of cube in liter = 15,625 x 0.001

Capacity of cube in liter = 15.625 liter

suppose 3 years ago Rose was 24 years older than her daughter at present Rose is 5 times as old as her daughter how old will be the daughter in three years time​

Answers

Answer:

Let Rose be R

Let her daughter be D

"3" yrs ago.

Subtract 3 from their ages

Rose was then (R-3) yrs old.

Daughter ..........(D-3)yrs old

So 3yrs ago.... Rose was 24yrs older than D.

Meaning

R=24+D

Which 3yrs ago can be expressed as

(R-3)=24+(D-3)

R - 3 = 24 + D - 3

R - D=24-3 + 3

R-D=24--------1

Now

At present.

R is 5times as old as Daughter

Meaning R = 5D-------2

Substituting into eqn 1

R-D=24

5D-D=24

4D=24

D=6yrs

Substitute D=6 into any equation of choice to get R

R-D=24

R=24+D

R=24+6

R=30yrs

Now we have Roses's age to be 30yrs and Daughter's age to be 6yrs.

We're asked to find the daughter's age in 3yrs time...

Meaning ....D+3

=6+3 = 9yrs

DAUGHTER WOULD BE 9YRS OLD IN 3YRS TIME.

The spread of a rumor in a town can be modeled as , where N is the number of people who have heard of the rumor, and t is time (in days). How long will it take until 2000 people know about the rumor?

Answers

Answer:

the time is 16 days

Step-by-step explanation:

The computation of the time period is given below:

N = 500 √t

2000 = 500 √t

√t = 4

Now do the square on both the sides

SO,

t = 16

Hence, the time is 16 days

We simply applied the above method to determine the time period

Find mEC.
5x - 27)
(2x - 5)
D

Answers

Answer:

Arc EC = 58°

Step-by-step explanation:

First, find the value of x.

m<D = ½(arc EC) => Inscribed Angles Theorem

Substitute

2x - 5 = ½(5x - 27)

Multiply both sides by 2

2(2x - 5) = 5x - 27

4x - 10 = 5x - 27

Collect like terms

4x - 5x = 10 - 27

-x = -17

Divide both sides by -1

x = 17

Find arc EC:

Arc EC = 5x - 27

Plug in the value of x

Arc EC = 5(17) - 27 = 85 - 27

Arc EC = 58°
