The Mitchells are renting a boat for the day. It costs $100, plus $20 for each hour. They have to pay for a whole hour even if they are not out there for a whole hour. For example if they boat for 3 and a half hours, they have to pay for 4 hours. They don't want to spend more than $250 for the day. How many hours can they boat? Write an inequality and solve.A)100 + 20x ≤ 250. They can boat for 7 hours.

B)100 + 20x ≥ 250. They can boat for 8 hours.

C)100 + 20x ≤ 250. They can boat for 8 hours.

D)100 + 20x ≥ 250. They can boat for 7 hours.

Answers

Answer 1

Answer: A)100 + 20x ≤ 250. They can boat for 7 hours.

Think of this logically. They want to spend less than $250 on the boat, so it can't be more than.

100+20*(7)=240

Answer 2

Answer: It would have to be A because B means they can spend over 250 dollars. C would be 260, which is over 250 and D means they could use the boat for more time, costing more money.

Answers

$\bf \textit{area of a trapezoid}\n\n A=\cfrac{h(a+b)}{2}~~ \begin{cases} a,b=\stackrel{bases}{parallel~sides}\n h=height\n[-0.5em] \hrulefill\n a=6\n b=10\n h=7 \end{cases}\implies A=\cfrac{7(6+10)}{2} \n\n\n A=\cfrac{7(16)}{2}\implies A=7(8)\implies A=56$

Answer:

Step-by-step explanation:

$A=(1)/(2) (b1+b2)h\n$

$A=(1)/(2) (6+10)7$

$A=(1)/(2) (16)7$

$A=8*7$

$A=56$

What is the value of the slope of the graph of distance versus time, and what does the slope represent?

Answers

To find the slope of the graph you pick any piece of the line, and divide the vertical difference between its ends by the horizontal difference between its ends. If the graph is distance versus time then the slope represents the speed.

You sell hotdogs for $1.25 each. Which equation can you use to find how many hotdogs you sold if you $60 from selling hotdogs?

Answers

To find the number of hotdogs sold, you can use the equation: 1.25x = 60, where x represents the number of hotdogs sold.

Answer: 1.25x=60
Divide 60 by 1.25 to get x alone and you'll have 48 hotdogs. To check, multiply 48 by 1.25 and you'll get 60.
