Please help me. I don’t know which phone contract is better.


I am going to change my phone contract. The monthly contract I am considering costs $30 per month with 75 minutes of free calls and 100 free text messages. Additional calls cost 10¢ per minute and additional text messages 10¢ each. An alternative is ‘Pay as you go’ which has no monthly charge but all calls cost 30¢ per minute and texts cost 10¢ each. I typically make 100 minutes of calls and 60 text messages each month. Which would be the better contract for me and by how much?

Answer:

-5 × 2 = -10

n ÷ -5 = 2

-10 ÷ -5 = 2

n = -10

Answer:

B = 3

Step-by-step explanation:

The answer has to be 3 because this is a 3-4-5 triangle. We can also you the Pythagorean theorem to solve for B.

a²+b²=c²

(4)²+b²=(5)²

16+b²=25

b²=9

√b=√9

b=3

Answer:

10^-1*2.65

Step-by-step explanation:

two hundred sixty-five thousandths= 0.265

We need a number between 1 and 10, to do the multiplication in standard form, so 0.265 turns into 2.65.

Because 2.65 becomes, smaller we use a negative power. We only move the decimal place once to the left, so we would multiply 2.65 by 10^1.

10^-1*2.65=0.265

The standard form of two hundred sixty-five thousandths is 265 × 10⁻³.

The number system is a way to represent or express numbers.

A decimal number is a very common number that we use frequently.

Since the decimal number system employs ten digits from 0 to 9, it has a base of 10.

Any of the multiple sets of symbols and the guidelines for utilizing them to represent numbers are included in the Number System.

Given that,

Two hundred sixty-five = 200 + 65 = 265

Now,

Thousandths mean we need to divide it by thousand

So,

⇒ 265/1000

⇒ 265/10³

By the law of indices

⇒ 265 ×  10⁻³

Hence "The standard form of two hundred sixty-five thousandths is 265 × 10⁻³".

Answer:

Step-by-step explanation:

1.7 - 2.7 - 1.34 + 4.9 - 1.48

First we can group the positive and negative numbers

1.7 + 4.9 - 2.7 - 1.34 - 1.48

add the positive numbers then add the negative numbers

1.7 + 4.9 becomes 6.6

-2.7 - 1.34 - 1.48 becomes - 5.52

Now add both the answers

6.6 + (- 5.52) = 1.08

Answer:

Hi there!

Your answer is:

A: -56

Step-by-step explanation:

-14=1/4 X

Solve for x!

Multiply both sides by the inverse of 1/4, which is 4! (1/4*4=1)

-14=1/4x

*4     *4

-56 = 1x

ALSO! Check your work!

-14= 1/4(-56) ??????

-14 = -14 YES

Your answer is A: -56

-14=1/4 X

Multiply both sides with the inverse of one over four (1/4*4=1)

-14=1/4x

*4     *4

-56 = 1x

Answer:

5/8

Step-by-step explanation:

If 3/8 IS raining, then the remaining 8ths is NOT raining. 8 - 3 = 5. So, 5/8 is NOT raining.

I hope this helps!

Answer:

5/8

Step-by-step explanation:

To find the probability of it not raining, subtract 3/8 from 1.

1 - 3/8

= 5/8

Since the probability of it raining is 3/8, this must mean that during the rest of the time, it will not rain.

So, the probability of it not raining is 5/8

Answer:

[tex]a_{n+1}[/tex] = [tex]a_{n}[/tex] + 6

Step-by-step explanation:

The terms have a common difference d between consecutive terms, that is

10 - 4 = 16 - 10 = 22 - 16 = 6

To obtain the next term add 6 to the previous term ( recursive rule ), thus

[tex]a_{n+1}[/tex] = [tex]a_{n}[/tex] + 6 with a₁ = 4

Answer:

d = 13

Step-by-step explanation:

For the lines to be parallel, then

5(2d - 3) and (6d + 11 + 2d) will be corresponding angles and congruent, thus

5(2d - 3) = 6d + 11 + 2d ← distribute left side

10d - 15 = 8d + 11 ( subtract 8d from both sides )

2d - 15 = 11 ( add 15 to both sides )

2d = 26 ( divide both sides by 2 )

d = 13

The value of d that makes lines e and f parallel is 13units.

It is required to find the value of d.

A line is a straight one-dimensional figure having no thickness and extending infinitely in both directions. A line is made of a set of points which is extended in opposite directions infinitely. It is determined by two points in a two-dimensional plane. The two points which lie on the same line are said to be collinear points.

Given:

For the lines to be parallel, then

5(2d - 3) and (6d + 11 + 2d) will be corresponding angles and congruent.

According to given question we have,

5(2d - 3) = 6d + 11 + 2d

Distribute left side we get,

10d - 15 = 8d + 11  

subtract 8d from both sides we get,

2d - 15 = 11  

Add 15 to both sides  we get,

2d = 26

Divide both sides by 2 we get,

d = 13units.

Therefore, the value of d that makes lines e and f parallel is 13units.

Answer:

y = 1/2x -8

Hope this helps!!

Answer:

y=1/2x-8

Step-by-step explanation:

When you are writing an equation, you will write them in the form y=mx+b. In this case, the m and the b are given to us so all we need to do is plug in the numbers and get the equation.  

Given:

The lake started with only  4 square feet infected.

The bacteria are growing by a factor of 3  every hour.

To find:

The domain for this situation.

Solution:

Initial value = 4 square feet

Growth factor = 3

Using exponential growth model, we get

[tex]y=ab^t[/tex]

where, a is initial value and b is growth factor.

So, square feet of bacteria after t hours is

[tex]y=4(3)^t[/tex]

Here, domain is set of values of time and range is square feet of bacteria.

Above equation is defined for all values of t but we know that, time cannot be negative.

As the relationship between hours and square feet of bacteria is  continuous, therefore the value of t can be any real number greater than or equal to 0.

[tex]Domain=\{t|t\in R\text{ and }t\geq 0\}[/tex].

Therefore, the domain is [tex]\{t|t\in R\text{ and }t\geq 0\}[/tex].
