Which e-reader has the greatest monthly subscription cost?

Answers

Answer 1

Answer:

[tex]A_4[/tex]

Step-by-step explanation:

The cost of the e-readers and the subscription of their services are

[tex]A_1(t)=5t+350[/tex]

[tex]A_2(t)=10t+250[/tex]

[tex]A_3(t)=499[/tex]

[tex]A_4(t)=15t+179[/tex]

The functions are of the form

[tex]A(t)=mt+c[/tex]

Where [tex]m[/tex] is the monthly subscription cost and [tex]c[/tex] is the cost of the e-reader.

So, 15 dollars is the highest subscription cost which is of the 4th e-reader.

Hence [tex]A_4[/tex] has the highest subscription cost.

what is 9.4 rounded to the nearest tenth?​

Answers

Answer: the answer is going to be 9

Answer:

9.4 rounded to the nearest 10th - 9

Step-by-step explanation:

If the tenth in the decimal is 4 or lower, (like 9.4 or 9.3) It would round down to 9, but if it were 5 or higher like (9.5) it would be 10.00 or 10 :)

Answers

Answer:

<C =10°

Step-by-step explanation:

The sum of angles in a triangle is 180°. Hence,

<C+<D+<E =180

Given

<C =x-4

<D = 11x-11

<E = x+13

Substitute

x-4+11x-11+x+13 = 180

13x-2 = 180

13x =180+2

13x = 182

x = 182/13

x = 14

Get <C

Since <C = x-4

<C = 14-4

<C =10°

Answer: <C =10°

Cameron needs to order some new supplies for the restaurant where he works. The
restaurant needs at least 598 spoons. There are currently 194 spoons. If each set on
sale contains 8 spoons, write and solve an inequality which can be used to determine
x, the number of sets of spoons Cameron could buy for the restaurant to have enough
spoons.

Answers

Answer:

Inequality: 8x+194_>598

Answer:x_>50.2

Step-by-step explanation:

I have delta math! I risked getting the answer wrong for this question lol. But this is correct just!

404 spoons are required for the restaurant for the fill needs.

What is inequality?

A difference between two values indicates whether one is smaller, larger, or basically not similar to the other.

A mathematical phrase in which the sides are not equal is referred to as being unequal. In essence, a comparison of any two values reveals whether one is less than, larger than, or equal to the value on the opposite side of the equation.

Inequality is just the opposite of equality for example 2 =2 then it is equal but if I say 3 =6 then it is wrong the correct expression is 3 < 6.

Let's say the number of sets required = x

Then,

8x will be the total number of spoons.

So,

8x + 194 ≥ 598

8x ≥ 404

x ≥ 50.5

A number of spoon required = 50.5 × 8 = 404 spoons.

Hence "404 spoons are required for the restaurant for the fill needs".

A. Juan wins the race

B. At about 7 minutes J(t )= A(t)

C. 2 minutes

Step-by-step explanation:

A. Juan wins the race. This is because she covers the distance in a shorter time interval than Antonio

B. At about 7 minutes J(t )= A(t). to get this, just look at the point that the two curves intersect on the graph, and trace it down to the time axis to read off the time.

C. J(t) is greater than A(t) with about 2 minutes. To get this, we just subtract the time Juan arrived at the finish line from the time Antonio arrived, this is = 15 -13 = 2 minutes

The proportional relationship between the number of inches a candle has burned away, b, at any time in hours, t, can be represented by the equation b = 0.25tb=0.25t. What is the constant of proportionality from the time in hours to the inches of candle that has burned away?

Answers

Answer:

k = 0.25t^2

Step-by-step explanation:

Given the equation :

b = 0.25t

b = number of inches that has burned away

t = time

From our knowledge of variation;

Since candle length will decrease with time ;

b α 1/ t

b = k/t

Where k is the proportionality constant

Comparing the equation :

b = 0.25t

k/t = 0.25t

k = 0.25t^2
