ii) p = 8

iii) p = 12

Step-by-step explanation:

First of all, we have the general relation as follows;

c = 2.79p

i) 2.79p = 11.16

p = 11.16/2.79

p = 4

ii) 2.79p = 22.32

p = 22.32/2.79

p = 8

iii) 2.79p = 33.48

p = 33.48/2.79

p = 12

The model y=1.8x−76.9 y=1.8x−76.9 represents the relationship between the temperature (°F) and the number of ice cream cones sold. Using the model, approximate the number of ice cream cones sold when it is 85°F. Round your answer to the nearest whole number.

Answers

Answer:

76 ice cream cones

Step-by-step explanation:

Given the model : y=1.8x−76.9 ;

Which shows the relationship between temperature and number of ice cream cones sold ;

Using the model, the predicted number of ice cream cones sold when temperature is 85°F

Hence, x = 85

Putting x = 85 in the model and solve for y

y = 1.8(85) −76.9

y = 153 - 76.9

y = 76.1

Hence, the number of ice cream cones sold is 76

Point A is located at -7 on a number line, and point B is located at 3 on the number line. Point C is the same distance away from point A as point B is from point A, but in the opposite direction. Which is the location of point C on the number line?

Answers

Answer:

C is at -17 on the number line

Step-by-step explanation:

point A is at -7, point B is at 3, that makes them 10 units away from each other, Point C is the same distance away from A just like B is but in the opposite direction. -7 -10=-17, therefor C is at -17

Find the missing terms in the arithmetic sequence 1, __, __, __, 29,...

Answers

9514 1404 393

Answer:

  8, 15, 22

Step-by-step explanation:

The sequence has ...

  a1 = 1

  a5 = 29

__

The generic formula for an arithmetic sequence is ...

  an = a1 +d(n -1)

Filling in the known information, we can find d:

  29 = 1 + d(5 -1)

  28/4 = d = 7

The terms of the sequence have a common difference of 7, so each is 7 more than the one before. The first five terms are ...

  1, 8, 15, 22, 29

The missing terms are 8, 15, 22.

ANSWER NOW PLEASE: Tom is having his car repaired. The cost of the parts is $260
and 4 hours of work are required. Tom needs to keep the
entire cost of the repair under $400. Which inequality
expresses the relationship between hourly cost (x), parts,
and the $400 limit?

Answers

Answer:

260 + 4x < 400

Step-by-step explanation:

To make our inequality, let's list out the separate costs we have, all of which combined should be less than 400.

First, we have the cost for the parts, which is $260. The other cost we have is the hourly rate for the work. The repair will take a certain amount of money for every hour worked. The rate must be low enough that it doesn't exceed $400 when combined with the $260 from the parts.

To construct our inequality, we can begin with the estalished $260.

Then, add to this the hourly rate, (x) times the number of hours worked, 4.

So we have-

260 + 4x

The total of this cost must be less than $400 dollars, so we will use the less than ( < ) sign in front of the 400.

260 + 4x < 400

The answer is 260 + 4x < 400. I hope this was helpful :] Good luck ^^

Let the number of apples be x and that of pears be y, then:

0.64x + 0.45y = 5.26 . . . (1)

0.32x + 0.39y = 3.62 . . . (2)

(2) x 2 => 0.64x + 0.78y = 7.24 . . . (3)

(1) - (3) => -0.33y = -1.98

y = -1.98 / -0.33 = 6

From (2), 0.32x + 0.39(6) = 3.62

0.32x = 3.62 - 2.34 = 1.28

x = 1.28 / 0.32 = 4

Answer:

Step-by-step explanation:

B

See image for question and answer choices

Answers

Answer:

B.

Step-by-step explanation:

So, lets remember a few things first.

#1: The formula for finding the answer is A^2+B^2=C^2

#2: A is the opposite side, B is the adjacent side, and C is the hypotenouse side.

Now lets plug in what we already know, and see if we canf igure out the annswer:

A^2+12^2=13^2

Now I am going to stop us here. This is your equation that will find the answer. In your question, they use x^2, A^2 is a variable you can use instead. But looking at this, answer B and my equation I wrote above are exactly the same.

If you want, here is how I further solved it, this might give you a better grasp on what to do for future problems:

Ok, not  too bad, the A is the unkown value, which is the opposite side.

Now, how do we figure this out? Well, we just need to sovle for A.

To do this, lets clean up our equation by first sqauring all the values(except for the unkown):

A^2+144=169

Ok, that looks better, now lets just subtract the adjeacent side(b), which is 144, from the hypotenouse side(c), which is 169.

This will now look like:

A^2=25(169-144=25)

Ok, just one more step to go. Just square root both sides of the equation, this way, we will get ride of the ^2 on A(opposite side), and get A alone.

([tex]\sqrt{A^2}=A[/tex])=([tex]\sqrt{25}=5[/tex])

A=5

This is your answer.

I don't understand what to do here. Can someone please explain?
