Step-by-step explanation:

Diego's family car holds 14 gallons of fuel. Each day the car uses 0.6 gallons of fuel. A warning light comes on when the remaining fuel is 1.5 gallons or less. Write an inequality to determine the number of days Diego's father can drive the car without the warning light coming on. 10 points 14− 0.6t > 1.5 14− 0.6t < 1.5 14+ 0.6t > 1.5 14+ 0.6t < 1.5

Answers

Answer:

[tex]14-0.6t>1.5[/tex]

Step-by-step explanation:

The amount of fuel the car holds is fixed i.e., 14 gallons

The amount of fuel consumed every day is 0.6 gallons

Warning light comes on when the fuel level is 1.5 gallons or less.

Let t be the number of days the car runs for

So the amount of fuel consumed in all the days must be less than 1.5.

The equation will be

[tex]14-0.6t>1.5\\\Rightarrow -0.6t>1.5-14\\\Rightarrow -0.6t>-12.5\\\Rightarrow 0.6t<12.5\\\Rightarrow t<\dfrac{12.5}{0.6}\\\Rightarrow t<20.83[/tex]

So, the number of days the car can be driven without the warning light coming on is less than 20.83 days.

Hence, the required inequality is [tex]14-0.6t>1.5[/tex].

The average emergency room cares for 300 patients each day. There are 20 nurses on duty at the emergency room each day, and they share the patient load equally.

Answers

Answer: 15

Step-by-step explanation:

You didn't say what you need to calculate but I guess that you want to calculate the number of patients each nurse will get.

Number of patients = 300

Number of nurses = 20

Number of patients to each nurse will be:

= Number of patients / Number of nurses

= 300/20

= 15

Each nurse gets 15 patient

Answer:

Step-by-step explanation:

There are 1$$ patients in the sample space.

There are 2$$ nurses on duty each day.

P(N)=3$$, is the probability that a patient will be assigned to a specific nurse.

Correct answers:

1$300$2$20$3$\frac{1}{20}$

The sample space is the set of all possible outcomes of an experiment. Here, there are 300 possible patients.

The event is a grouping of the outcomes in the sample space. Here, there are 20 possible nurses that a patient may have.

When the 300 patients are assigned equally to 20 nurses, that is equal to 15 patients per nurse.  The probability of a patient being assigned to a specific nurse, N, is the comparison of being assigned to that nurse's patients versus all possible patients: P(N)=15/300=1/20.

Politician Alec and Candidate Simeon are running for governor. The latest surveys show that Politician Alec has 47% of the vote, while Candidate Simeon has 42% of the vote. The news report, however, states that this survey has a 6 % margin of error. What interval describes Politicians Alec's chances of winning the election?

Answers

Answer:

(41%, 53%)

Step-by-step explanation:

Given that:

Politician Alec's vote = 47%

Candidate Simeon = 42%

Margin of Error = 6%

Interval which describes Alec's chances of winning

Chances of Alec winning (p) = 47%

Margin of Error = 6%

Interval :

p ± margin of error

47% ± 6%

47% - 6% ; 47% + 6%

(41%, 53%)

Step-by-step explanation:

Both have a slope or "rate of change" of 1/2 because going from (0,5)-->(2,6) on the first one you go right 2 units and up 1 and slope is rise over run or y/x values in this case it would be 1/2 and on the bottom function you can see it goes from (0,-2)-->(4,0) and this goes right 4 units and up 2 units same principal applies you get 2/4 which is equal to 1/2 also it being negative or not doesn't change whether the two functions have the same rate of change.

Answer:

C ($1834.44)

Step-by-step explanation:

Compound interest formula: P = T (1+ r/100)^t

Where

P is the Total amount of money at the end of the time period

T is the money invested at the start

r is the interest rate

and

t is the time by which interest is compounded

Since interest is compounded quarterly,

r is divided by 4 and T is multiplied by 4

therefore,

Total amount = $1800.00( 1 + 1.9÷4/100) ^1×4

= $1834.44

Jake plans to use a ramp to make it easier to move a piano out of the back of his truck. The back of the truck is 83 centimeters tall and the ramp is 158 centimeters long

Answers

Given :

Height of the ramp, h = 83 cm.

Length of ramp, L = 158 cm.

To Find :

Length of the base of the ramp.

Solution :

Let length of the base is l.

By Pythagoras theorem :

L² = h² + l²

[tex]l=\sqrt{L^2-h^2}\\\\l=\sqrt{158^2-83^2}\\\\l=134.44\ cm[/tex]

Therefore, length of the base is 134.44 cm.

Hence, this is the required solution.
