Answer:

Step-by-step explanation:

Given that Nadya's uses the service for up to 200 times then

let let c represent the cost of Nadya's bill

and m be the minutes of airtime

therefore

the initial charger is $35

The charge per additional minutes is $0.23

c=35+0.23m

Therefore the expression is

c=35+0.33m

Answer:

20 Years.

Step-by-step explanation:

As you could see my friend owned a dog for 9 years, and it reads that it is one year less which is 10 years since 10-1 (aka one year) equals 9 so anyways we know it's 10, and it's twice as long 10 x 2 (aka twice). which is how I got my answer... 20!

Answer:

The toy rocket will return to the ground at 8.44 seconds

Step-by-step explanation:

The height h of the toy rocket launched vertically as a function of the time t is given by:

[tex]h(t)=-16t^2+135t[/tex]

The rocket will return to the ground when h=0:

[tex]-16t^2+135t=0[/tex]

Factoring:

[tex]t(-16t+135)=0[/tex]

There are two solutions:

t=0, t = 135/16 = 8.4375

The first solution corresponds to the moment the toy rocket was launched, the second is the time taken by the rocket to return to the ground.

The toy rocket will return to the ground at 8.44 seconds

Answer:

1. Putting  x = 0.5, y = -1/10 gives  0.44

2. Putting  x = -1, y = -3  gives 14

3. Putting x =3/4 , y = 2/5 gives 1.665

4. Putting  x = 0, y = 2.5 gives - 11.25

5.  Putting x = √2, y = √2 gives 17

6. Putting x = 2, y = -1  gives - 1

Step-by-step explanation:

-3x2 + 2y2 + 5xy - 2y + 5x2 - 3y2

1. Putting  x = 0.5, y = -1/10

-3(0.5)^2 + 2(-1/10)^2 + 5(-0.05) - 2(-1/10) + 5(0.5)^2 - 3(-1/10)^2

= -0.75 +0.02 - 0.25 +0.2 + 1.25- 0.03

= 0.44

2. Putting  x = -1, y = -3

-3(-1)^2 + 2(-3)^2 + 5(3) - 2(-3) + 5(-1)^2 - 3(-3)^2

= -3 +18 +15+6+5-27

= 14

3. Putting x =3/4 , y = 2/5

-3(3/4)^2 + 2(2/5)^2 + 5(6/20) - 2(2/5) + 5(3/4)^2 - 3(2/5)^2

=- 27/16 +8/25 +30/20 -4/5 +45/16 - 12/25

= 18/16 - 24/25 + 30/20

= 18/16 - 96+150/100

= 18/16 +54/100

= 1800+ 864/1600

= 2664/1600

=1.665

4. Putting  x = 0, y = 2.5

-3(0)^2 + 2(2.5)^2 + 5(0) - 2(2.5) + 5(0)^2 - 3(2.5)^2

= 12.5 - 5.0 - 18.75

= -11.25

5.  Putting x = √2, y = √2

-3(√2)^2 + 2(√2)^2 + 5(√2.√2) - 2(√2) + 5(√2)^2 - 3(√2)^2

= -6 +4+10-4+19-6

= 17

6. Putting x = 2, y = -1

-3(2)^2 + 2(-1)^2 + 5(-2) - 2(-1) + 5(2)^2 - 3(-1)^2

= -12+2 -10 +2 +20 -3

= -1

Answer:

4.25

Step-by-step explanation:

-x^2 + 3x + 2 = 0

Divide by -1

X^2 -3x - 2 = 0

x^2-3x+ =2+2.25

(x-1.25)-4.25

(x-1.5)

Answer:

12,5 centimeters.

Step-by-step explanation:

We take the following proportion

[tex]\frac{1 cm}{80m} = \frac{x}{1000m}[/tex]

Which becomes:

[tex]1000 = 80x[/tex]

And then, we clear out the variable x:

[tex]\frac{1000}{80}=\frac{100}{8}=\frac{50}{4}=12,5[/tex]

And this means that the width of the lake on the scale drawing will be 12.5 cm.

Answer:

$4000

Step-by-step explanation:

use formula a = w*p

1200.00 = w0.3

/ 0.3          /0.3

w = 4000

The total earnings done by Jackson last month will be equal to 4000.

The Latin term "per centum," which signifies "by the hundredth," was the source of the English word "percentage." Segments with a denominator of 100 are considered percentages. In other terms, it is a relationship where the worth of the entire is always considered to be 100.

As per the given information provided in the question,

Total investment is done by Jackson = 1200

The investment is 30% of total earnings.

Assume that Jackson's earnings are x.

Then,

30% of x = 1200

x = 1200 × (100/30)

x = 4000

Answer: 14 pieces

Step-by-step explanation:

Let the number of pieces of paper she had at first be x.

Before starting she got seven more pieces to use. This can be written as:

= x + 7

When she was done she had 28 half pieces of paper. This can then be written as:

x + 7 = (28 × 1/2)

x + 7 = 14

x = 14 - 7

x = 7

Since x = 7, she started with:

= x + 7

= 7 + 7

= 14 pieces

Answer:

The correct answer is x =55°

Answer:

No, the administrator is wrong.

[tex]Adult = 500[/tex]

Step-by-step explanation:

Given

[tex]Total = 931[/tex]

[tex]Children = 423[/tex]

[tex]Adult = 408[/tex]

Solving (a): Is the administrator correct?

No, the administrator is wrong.

This is so because: when the number of children is subtracted from the total patient, the remaining number is not 408

Solving (b): Estimate the number of adults

By rounding up:

[tex]Adult = Total - Children[/tex]

Actual Figures

[tex]Adult = 931 - 423[/tex]

Round up

[tex]Adult = 900 - 400[/tex]

[tex]Adult = 500[/tex] -- approximately
