Step-by-step explanation:

I am BIG brain

Answer:

160

Step-by-step explantion

The train leaves at  10:20 AM and arrives at 1:00 PM.

It takes 2 hours and 40 for the train to arrive at Stamford.

1 hour = 60 miles

SO

60+60+60*2/3=160

Answer:

Part A

Domain = input values

Range = output values

Therefore, if the domain is {10, 45, 72, 100} then input those values into the function:

P(10) = 8.50(10) - 600 = -515

P(45) = 8.50(45) - 600 = -217.5

P(72) = 8.50(72) - 600 = 12

P(100) = 8.50(100) - 600 = 250

So the range is {-515, -217.5, 12, 250}

Part B

The domain is the number of binders sold

The range is the profit in dollars

Part C

Set the function to >0:

⇒ P(b) > 0

⇒ 8.50b - 600 > 0

add 600 to both sides:

⇒ 8.50b > 600

divide both sides by 8.50:

⇒ b > 70.58823529...

Therefore, the minimum number of binders the store needs to sell in order to make a profit is 71.

Part D

If the store sells a minimum of 71 binders, then substitute b = 71 into the function and solve to find the minimum profit:

⇒ P(71) = 8.50(71) - 600

⇒ P(71) = 603.5 - 600

⇒ P(71) = 3.5

Therefore, the store will make a minimum of $3.50 profit if it sells at least 71 binders.

However, if the store sells less than 71 binders, it will make a loss.

if z = 8

then

-2 + (-8) = - 10

not 10

-2 + z = 10

-2 + 2 + z = 10 + 2

z = 12

check

-2 + (+12) = +10

Answer:

72

Step-by-step explanation:

Just add up 45.3+26.7

45.3 + 26.7 = 72

Answer:

y= 72°

Step-by-step explanation:

If you add the two degrees you get 72.

45.3+26.7=y

45+26=71

.3+.7=1

71+1=72

Answer:

Step-by-step explanation:

Take the square root of both sides.

sqrt(x - 4)^2) = +/- sqrt(7)

x - 4 = +/- sqrt(7)                Add 4 to both sides

x = 4 +/- sqrt(7)

Answer:

3

Step-by-step explanation:

Since you need to find the y value when x = -1, go to -1 on the x axis, and find where the green line crosses. The green line goes through the point (-1,3), or one box to the left and three boxes up, so the y value is 3.

Hopefully this helps- let me know if you have any questions!

Answer:Find the point in which the x = 1, and the y  point meets.

When x = 1, y = 2

Answer:

Number of chirps per minute = 68

Step-by-step explanation:

Given:

​T = 50+ (N - 40)/4

where,

T is a temperature in degrees Fahrenheit

N is a number of chirps per minute

Find n when T = 57°F

​T = 50 + (N - 40)/4

57 = 50 + (N - 40)/4

57 - 50 = (N - 40)/4

7 = (N - 40)/4

Multiply both sides by 4

7 × 4 = (N - 40)/4 × 4

28 = N - 40

28 + 40 = N

68 = N

N = 68

Number of chirps per minute = 68

[tex]\frac{4}{10}[/tex]Answer:

-2/5

Step-by-step explanation:

-[tex]\frac{2}{5}[/tex] ÷[tex]\frac{2}{1}[/tex]= -[tex]\frac{2}{5}[/tex]×[tex]\frac{1}{2}[/tex]=-4/10=-2/5

When dividing fractions you follow a rule called Keep change flip or KCF. You keep the first fraction in this case -2/5 then u change the symbol so from ÷ to × and then u flip the fraction. You then solve like you would a multiplication fraction.

Answer:

m = 2.4 and b = 14.8

Step-by-step explanation:

In slope-intercept form, all equations follow the formula y = mx + b, in which equations are parallel as long as they have the same slope, represented by the variable m. All that the b variable does is change the y-intercept. Knowing this, in order to find a parallel equation to y = 2.4x + 5.2 that intercepts the point (-2, 10), the only variable that can change is the b variable. The first step is to plus -2 into the x variable. This will grant you y = 2.4(-2) or y = -4.8, which will then allow you to find what the b variable should be by subtracting -4.8 from 10. This will grant you b = 14.8, and since you know the slope must stay the same, the final answers are m = 2.4 and b = 14.8.
