Answer:

332

the reason why I think it's $332 is because if you do 1,994 / 6 then that equals 332 I don't know if you get it right if you do great job if you don't I understand

Answer:

28h = 56

Divide by 28 on both sides

H = 2

Answer:

2

Step-by-step explanation:

28 per hour

56 per ? hours

Use the equation:

56 = 28 h

Divide 56 by 28

56 / 28 = 28 h /28

56/28 = 2

2 = h

Therefore, it will take 2 hours for the boat to cross a bay of 56 mil

Answer:

See attachment >_<

Step-by-step explanation:

Because the line includes the point [tex](0,3)[/tex], we'll begin our line at this coordinate.

The slope is [tex]7[/tex], or, [tex]\frac{7}{1}[/tex]. Slope is formatted in the [tex]rise[/tex] in the line over its [tex]run[/tex]. Or, [tex]\frac{rise}{run}[/tex]. This means the line rises [tex]7[/tex] units and runs [tex]1[/tex] unit.

From our beginning point, [tex](0,3)[/tex], move up seven units and then to the right one unit.

If this line was negative (it would have a negative slope), we would run to the left. However, we have a positive slope, so we will run to the right.

By doing this, we land on the point [tex](1,10)[/tex]. Draw a line through this point with our beginning coordinate [tex](0,3)[/tex]. This is our graphed line. I've attached a photo as well :)

Good luck ^^

Step-by-step explanation:

Answer:

-3n²+n³

Step-by-step explanation:

Since the unknown number is n;

Product of the number and negative three is -3n

square of the number is n²

Taking their sum;

Sum = -3n + n²

Hence the sum of the product of the number and negative three and the square of the number is -3n+n²

If a number n is multiplied by the sum of the product of the number and negative three and the square of the number, hence the required function is;

f(n) = n(-3n + n²)

Expand

f(n) = -3n²+n³

This gives the required function

Answer:

32589.77701

Step-by-step explanation:

1000000000=30683x+47872

x=1000000000-47872/30683

Therefore,x=32589.77701

Answer:

y= -5/2x + 3/2

Step-by-step explanation:

(3,-6). y=mx+b or -6=-5/2 × 3+b, or solving for b: b=-6-(-5/2)(3). b=3/2.

(-1,4). y=mx+b or 4=-5/2 × -1+b, or solving for b: b=4-(-5/2)(-1). b=3/2.

Plugging in the two points, hence y= -5/2x + 3/2

Answer:

x = 41°

Step-by-step explanation:

Angle ABC is an inscribed angle because it has a vertex on the circle. Therefore, we can say that angle ABC is equal to half the arc it intercepts, which is AC. Since AC is equal to 82°, angle ABC would be half of that, or 41°.

Answer:

Answer:

A = 175, B = π/6, C = 345

Step-by-step explanation:

The given variation of the volume in the tank and time includes are;

At t = 0 the volume in the tank, y = Maximum volume, [tex]y_{max}[/tex] = 520 gallons

At t = 6 the volume in the tank, y = Minimum volume, [tex]y_{min}[/tex] = 170 gallons

The function that models the situation is y = A·cos(B·x) + C

Given that the function that models the situation is the cosine function, we have;

A = The amplitude = (The maximum - The minimum)/2

∴ A = (520 - 170)/2 = 175

A = 175

The period = The time to change from maximum to minimum = 2 × The time to change from maximum (t = 0) to minimum (t = 6)

∴ The period = 2 × (6 - 0) = 12

The period = 12 seconds = 2·π/B

∴ B = 2·π/12 = π/6

B = π/6

C = The vertical shift = Th minimum + A = (The maximum + The minimum)/2

∴ C = (520 + 170)/2 = 345

C = 345

I think its the third one ig...

Answer:

Use the x method

Step-by-step explanation:

Move the 10 over to the other side and get x^2 - 3x -10 = 0 and solve by finding two numbers that add up to negative 3 but multiply to -10 which would be -5 and 2 so the binomials are (x-5)(x+2)

Answer:

x^2 - 3x = 10

Step-by-step explanation:

Move all terms to the left side.

Use the sum product pattern.

Factor (x-5)(x+2) = 0

Create two separate equations,

x - 5 = 0, and x + 2 = 0

Rearrange and isolate the variable.

x = 5

x = -2

Answer:

The GCF for the variable part is ab².

GCFVariable=ab²

Multiply the GCF of the numerical part 5 and the GCF of the variable part ab².

Answer:

150%

Step-by-step explanation:

Percent change =   [tex]\frac{New - Old}{|Old|}[/tex] × 100%

=> [tex]\frac{10000-4000}{4000}[/tex] × 100

=> [tex]\frac{6000}{4000}[/tex] × 100 = 150% (increase)

Answer:

y=-5x+2

Step-by-step explanation:

Before we get started, we should identify slope-intercept form.

y=mx+b.

Step 1 : Isolate the y by dividing everything by 3.

(15x+3y=6)/3 = 5x+y=2

Step 2 : Move the x value to the right side.

y=-5x+2

Answer:

y=5x-2

Step-by-step explanation:

15x+3y=6

3y=15x-6....both side divide by 3

y=5x-2

Because each bus is assigned 1 class and there is only five buses so there are 5 classes

Answer:

D 0.75

Step-by-step explanation:

There are a total of 4 pairs: White-Summer, Black-Summer, White-Winter, and Black-Winter. There are a total of 8 socks.

The probability of pulling a black sock or a summer sock is the number of all black or summer socks divided by the total number of socks.

The number of black or summer socks includes 1 pair of White-Summer, 1 pair of Black-Summer, and 1 pair of Black-Winter.

This makes for 6 black or summer socks.

Divide 6 by 8 to get 0.75

Answer:

a=2

b=2

Step-by-step explanation:

This is a special 45-degree right triangle. Two angles equal 45 degrees, and then there is a right triangle. In these triangles, the hypotenuse is equal to [tex]k*\sqrt{2}[/tex] where k is equal to the legs (a and b). So, to find the legs divide [tex]k*\sqrt{2}[/tex] by [tex]\sqrt{2}[/tex]. This equals 2, and since a and b are congruent both a and b equal 2.

oml, this is false. truely false!!

hope this helps ya! :)
