Answer:

104 dollars

Step-by-step explanation:

Answer:

f(t) = 0.85(21,000)

Step-by-step explanation:

100% - 15% = 85% 0r in decimal form 0.85

0.85 x the original pricen 21,000

Answer:

the answer for this question is: f(t)=21,000(0.85)^t

Step-by-step explanation:

well since its asking what function represents the value, you have to convert the 15 percent into a decimal. so when you put the equation together you can see its 0.85.

hope it helps! :)

Answer: D and E

the answers is between 1 and 2 so A is out

the dot is a little more than halfway so B and C are out

D and E are left :)

Answer:

D E

Step-by-step explanation:

Answer:

The listed size is 32 inches

Step-by-step explanation:

Given

See attachment for television

Required

The listed size

The listed size is calculated by the diagonal of the television.

This is calculated as using Pythagoras theorem as follows:

[tex]Diagonal^2 = Length1^2 + Length2^2[/tex]

Where:

[tex]Length1 =28in[/tex]

[tex]Length2 =15.7in[/tex]

So, we have:

[tex]Diagonal^2 = 28^2 + 15.7^2[/tex]

[tex]Diagonal^2 = 784 + 246.49[/tex]

[tex]Diagonal^2 = 1030.49[/tex]

Take positive square roots of both sides

[tex]Diagonal = \sqrt{1030.49[/tex]

[tex]Diagonal = 32[/tex] --- approximated

Hence, the listed size is 32 inches

Answer:

2) 67.8°

3) 46.8°

4) 56.0°

Step-by-step explanation:

Use the right triangle trig functions

sine, cosine, or tangent and take the inverses to find the angle

Answer:

Step-by-step explanation:

It is assumed the angles A and C are congruent:

m∠A = 3*5 + 40 = 55°

Answer:

solution given:

m<a=m<c

3x+40=x+50

3x-x=50-40

x=10/2=5

now

<a=3×5+40=55°

m<a=55° is your answer

Answer:

16 girls to 20 boys

Step-by-step explanation:

Answer:

A ( -d , e )

B ( - d , -e )

C ( d , - e )

Step-by-step explanation:

The centroid of the circle is on the origin.

This means that coordinates are an equal distance away from each other

Ex. Coordinate A and coordinate B are an equal distance away.

The only difference between the coordinates is the signs of the x and y values

This is determined by what quadrant the specific coordinate is in

Ex. Coordinate A is in Quadrant 2.

Coordinates in Quadrant 2 have a negative x value and a positive x value

Because Coordinate A and the given coordinates ( d , e )  have an equal distance between them all we have to do to find the missing coordinate is add a negative sign in front of the x value (d)

That being said, the coordinate of A is (-d,e).

This process is used to find the rest of the missing coordinates

for B

B lies in Quadrant 3

Quadrant 3 = ( -x , -y )

* add negative signs to the x and y value of the given coordinate *

B  = ( -d , - e)

For C

C lies in Quadrant 4

Quadrant 4 = ( x , - y )

* add a negative sign to the y value of the given coordinate *

C = ( d, -e)

Answer:

122

Step-by-step explanation:

The first thing to notice is that <EBC and <ABE form a straight line. This means they are a linear pair, also known as complementary. So, when they are added together they will equal 180 degrees. Therefore, to solve, set up and solve the algebraic equation, 180=58+x. When 58 is subtracted from both sides, you are left with x=122.

Answer:

$235.69

Step-by-step explanation:

Add 10.6875 to 225

Answer:

$235.69

Step-by-step explanation:

Answer:

0.7x - 1.4 =-3.5

      +1.4   +1.4    Step one: add 1.4 to both sides to cancel out 1.4

0.7x = -2.1

----      -----         Step two: divide both sides by 0.7

0.7      0.7

x = -3              The answer is x = -3.

Answer:

Step-by-step explanation:

y = x is your answer ❤️.....

Answer:

y = 1x

Step-by-step explanation:

(0,0) (-5,-5)

y2 - y1 / x2 - x1

-5 - 0 / -5 - 0

- 5 / -5

1

y = 1x + b

-5 = 1(-5) + b

-5 = -5 + b

0 = b

Answer:

I belive the answer would be B

Step-by-step explanation:

Answer:

7a + b - 16c

Step-by-step explanation:

So we have

7a-3b+c-8c+4b-9c

When it comes to problem like these, you need to combine like terms.

There's only one 'a' number, so that one remains the same.

Next, we have -3b and 4b. (-3b+4b)= b

Finally, there's (c-8c-9c).

(-8c-9c)= -17c

Take that and add the positive 'c' to it.

(-17c+c)= -16c

Put it all together now to get:

7a + b - 16c

I hope that helped and helped you understand at least a little

Answer:

[tex]A=1250m^2[/tex]

Step-by-step explanation:

From the question we are told that

Dimension of drawing

20 centimetres by 10 centimetres

Scale of drawing

1 cm:250 cm

Generally the the Main dimension of the pool is mathematically given as

[tex]L=length\ of\ scaled\ pool*250 cm\\B=length\ of\ scaled\ pool*250 cm\\L=20*250=5000 cm=50m\\B=10*250=2500 cm=25m[/tex]

Therefore Area Aof main pool is mathematically given as

[tex]A=50m*25m=1250 m^2[/tex]

[tex]A=1250m^2[/tex]
