Answer:

718\ min

Step-by-step explanation:

Let

x ----> the number of minutes

y ----> the total charge in dollars

we know that

For x>700 min

y=0.45x+40

so

For y=48.10

substitute

48.10=0.45x+40

Multiply by 100 both sides

4,810=45x+4,000 ----> equation without decimals

solve for x

45x=4,810-4,000\\45x=810\\x=18\ min

To find out the total minutes we need to sum

18\ min+700\ min=718\ min

selena walks home to school each mm morning and back home each afternoon. altogether she walks 2/3 mile wach day. how far does s
LenaWriter [7]

Answer:



One days trip of to school from home and back home from school is 2/3 of a mile. We want to know how far it is to school from her house.

To solve this, we simply need to take half of the total distance (2/3)

\frac{2}{3} / 2

Next, we need to turn the 2 into a fraction. Every whole number can be made into a fraction by putting it over 1.

\frac{2}{3} / \frac{2}{1}

Because we are dividing, we need to invert the second fraction and then multiply.

\frac{2}{3} * \frac {1}{2}

Next, we multiply the top of the first fraction by the top of the second and the bottom of the first fraction by the bottom of the second.

\frac{2}{6}

Once you reduce, you get:

\frac{1}{3}

3(2x+8)=8x+46 answer
MrMuchimi
3(2x+8)=8x+46
6x+24=8x+46
-2x+24=46
-2x=22
x=-11

3(2(-11)+8)=8(-11)+46
3(-22+8)=-88+46
3(-14)=-42
-42=-42

A charity organization had to sale 18 tickets to their fundraiser Just to cover necessary production cost.They sold each ticket
Harman [31]

A charity organization had to sale 18 tickets to their fundraiser Just to cover necessary production cost.They sold each ticket for $45.Let y represent the net profit in dollars when they have sold x tickets

Which of the following information about the graph of the relationship is given?

Choose 1 answer:

A

Slope and x-intercept

B

Slope and y-intercept

C

Slope and a point that is not an intercept

D

x-intercept and y-intercept

E

y-intercept and a point that is not an intercept

F

Two points that are not intercepts

Answer:

A. Slope and x-intercept

Step-by-step explanation:

We are told that each Ticket cost $45 , so the number of ticket sold should be multiplied by the cost of 1 ticket , Also; we were informed that x tickets were sold, this implies that the amount will be $45 multiplied by x , which is $45x. To find the profit (y) , then we must find the cost of 18 tickets which will give us the cost price and then subtract it from the selling price ($45x).

NOW:

Given that :

a charity organization had to sell 18 tickets

and one ticket cost for $45

Then 18 tickets = $45 × 18 = $810

Let y represent the net profit in dollars when they have sold x tickets

So : y = 45 x - 810

Relating the above equation with equation of a straight line  y = mx +c ,

where :

m and c = the numbers on the gradient line   ; &

y = slope

x =  intercept where the graph crosses y - axis

Thus; the information given is the :Slope and x-intercept

A rectangular bathroom tile is 2 1/3 times as wide as it is tall.If the tile is 5cm tall,how wide is it?
Neko [114]
The width of the rectangular bathroom tile is 11 and 2/3 centimeters. Taft is because 2x5 is 10 cm and 1/3x5 is 5/3. 5/3 simplified as a mixed number is 1 and 2/3. 1 and 2/3 combined with 10 is 11 and 2/3 centimeters.
