can someone pls explain to me how to find y intercept

a machine can pack a 3 ft by 3 ft by 1 ft carton with packing material in 3 seconds Then it would take 32 seconds to fill a carton that measures 4 ft by 4 ft by 6 ft

1) we calculate the volume of the first carton:

volume=length x width x height

volume=3 ft * 3 ft * 1 ft=9 ft³

Therefore:

A machine can fill 9 ft³ in 3 seconds.

2) we calculate the volume of the second carton.

volume=length x width x heigth

volume=4 ft * 4 ft * 6 ft=96 ft³

3) we calculate the time that the machine needs for fill the second carton with packing material by the rule of three.

9 ft³---------------------3 seconds

96 ft³--------------------      x

x=(96 ft³ * 3 seconds) / 9 ft³=32 seconds.

Hence , a machine can pack a 3 ft by 3 ft by 1 ft carton with packing material in 3 seconds Then it would take 32 seconds to fill a carton that measures 4 ft by 4 ft by 6 ft

Answer:

1080 total inches of ribbon. 60 pieces of ribbon can be cut.

Step-by-step explanation:

Firstly, the dressmaker has 15 rolls of ribbon that are 6 feet in length. Multiply those to see how many feet in total, 90. Then multiply this by 12 (there are 12 inches in a foot) to get the amount of total inches: 1080.

This is the answer to the question below the problem.

To answer the bigger question at hand:

You would need to take 1080 divided by 18 to find how many pieces the dressmaker can cut. She can cut exactly 60 pieces from her 15 rolls of ribbon.

The total bill of 3.18 pounds of grapes, 1.35 pounds of peaches, and 2.48 pounds of apples is $ 8.4.

Given that,

I bought 3.18 pounds of grapes, 1.35 pounds of peaches, and 2.48 pounds of apples.

Grocery Store Prices:

Grapes $1.29 per pound

Peaches $1.19 per pound

Apples $1.09 per pound

Therefore the total bill is = $ [(3.18 pounds x 1.29 per pound) + (1.35 pounds x 1.19 per pound ) + ( 2.48 pounds x 1.09 per pound)]

= $ ( 4.10 + 1.60 + 2.70)

Answer:

10/9

Step-by-step explanation:

We can calculate f(3) and g(-4)

f(3) = 4*3 - 2 = 12 - 2 =10

and g(-4) = -2 * (-4) + 1 = 8 + 1 = 9

Then it is easy to calculate f(3)/g(-4):

f(3)/g(-4) = 10/9

where we use the values which we calculated before.

⇒In the equation f(x) given f(3) plug in the value 3 in the place of x and simplify

[tex]f(3)=4(3)-2\\f(3)=12-2\\F(3)=10[/tex]

⇒For g(-4) in the place of x plug in -4 in the equation of g

[tex]g(-4)=-2(-4)+1\\g(-4)=8+1\\g(-4)=9[/tex]

Now we can find the value of  of the problem as done BELOW:

[tex]\frac{f(3)}{g(-4)} \\\frac{f(3)}{g(-4)} =\frac{10}{9}[/tex]

Answer:

[tex]h = \dfrac{T - r}{n}\\\\\text{Hourly rate } = \$45\;\;\text{if T = 200, r = 20 and n= 4}[/tex]

Step-by-step explanation:

We have from #14 that
T = r + nh

where T = amount charged, n = hours worked, r = fixed rate and h = hourly rate

Subtract r from both sides:
T - r = r + nh - r

The r terms on RHS of the equation cancel out
T - r = nh

Divide both sides by n:
(T - r)/n = h

Or we can write it as
h = (T - r)/n

If r = 20, , T = 200 and n =4 we get by substitution

h = (200-20)/4

h = 180/4

h = 45

So hourly rate = $45

Answer:

On solving the inequality we get -6>5 which is not possible; hence there is NO SOLUTION possible for s.

We solve the given inequality for s as follows

2(4s-3) ≥ 5+8s

⇒8s - 6≥ 5 +8s

⇒ -6 > 5               (on subtracting 8s from both sides)

the last statement shows that variables cancel out from both sides of the inequality and we get -6>5 which is not possible. Because -6>5 is not possible or false, hence no value of s will be able to satisfy the given inequality. Thus the answer for s is NO SOLUTION.

The similarity is the common slope

The difference is the y–intercept

The slope is the ratio of the rise to the run of the graph.

The given function is; 2•x + 3•y = 1470

Where;

x = The number of sandwich sold

y = The number of wraps sold

The profit per sandwich sale = $2

Profit per each wrap sale = $3

Where;

m = The slope

c = The y–intercept

Therefore, 2•x + 3•y = 1470 gives;

They will together take 18 minutes to finish the sanitization work together.

It is mentioned that Liana can sanitize the guest room in 45 minutes only and Gab, her brother, can do the same in 30 minutes.

Let they take y minutes to finish the work together.

Let the total work be m

Workdone by Liana in 45 mintues = m

∴Workdone in 1 minute = m / 45

Workdone by Gab in 30 minutes = m

∴Workdone by Gab in 1 minute = m / 30

Let the total time taken by them = x minutes.

Total time taken by them together = m / 45 + m / 30

∴ [tex]\frac{m}{45} +\frac{m}{30} = \frac{m}{x}[/tex]

The estimated probability that the sum of five dice will be 26 is 0.0053

Estimated Probability: Estimated probability is an approximation, or estimate, of theoretical probability. The larger the number of trials, the more accurate we expect this approximation to be. If E consists of a single outcome s, we refer to P(E) as the probability of the outcome s, and write P(s) for P(E)

N = Number of Repeated Process = 10,000

n = Number of times the sum of the five tosses equaled 26 = 53

The estimated probability that the sum of the five dice will be 26 = n/N

Where n = 53

And N = 10,000

Using the above formula, we have the following:-

n/N becomes

n/N = 53/10,000

n/N = 0.0053

Hence, the estimated probability that the sum of five dice will be 26 is 0.0053

The given graph is of the function of the form y = 3(2ˣ )

A function is a set of rules that assigns each element of a set a unique element of another set.

If f is a function and f(x) = x+2, then if we have to check x= 1 , y=3 put these values in y = x + 2 , 3 =1+2 (true)

Given that the graph of a function in the form y =f(x) = a b ˣ

From the graph in the question : The function passes through two points

(1,6) and  (0, 3 )

From point (0,3 ) it gives that  when x= 0 ⇒ y = f(x) =3

Answer:

Step-by-step explanation:

35+35= 70 right?

So then would have to subtract the 70 from 180  because that is total length of an angle to get 110 degrees

110 degrees

I might be wrong, because it might be different with triangles

Answer:

U = 110

Step-by-step explanation:

The formula for finding missing angle is.

a + b + c = 180   or in this case   S + U + T = 180.

You already have the measurement of two angles so plug those in.

35 + U + 35 = 180

Now all you have to do is simplify and solve it.

35 + 35 + U = 180  

70 + U = 180   you simplify by adding together 35.

U = 110     to cancel out 70 and isolate U you subtract 70 to both sides.
