Step-by-step explanation

First, we need to convert 2 2/3 hours to minutes. This would be:

= 2 2/3 × 60 minutes

= 8/3 × 60 minutes

= 160 minutes

Since water goes over a waterfall at a rate of 162 1/2 gallons every 15 minutes. The the gallons of water going over the waterfall in 2 2/3 hours would be:

= (162 1/2 × 2 2/3hours) / 15 minutes

= (162 1/2 × 160) / 15

= 1733 1/3 gallon

Step-by-step explanation:

Answer:

Yes it is proportional (Equation: y=3.5x)

Step-by-step explanation:

Notice that there is a constant change in y and a constant change in x. But by how much? Given the last point (13,45.5) we can see that 13-12=1 and 45.5-42=3.5 so that means as x increases by 1, y always increases by 3.5, making the relationship proportional. You can also write the equation y=3.5x to show this

Answer:

7

Step-by-step explanation:

the left side is 9+18=27

so the right side is 20+x=27

and 27-20=7

Answer:

f(x)=(x+3)^2+5

let f(x)=y

y=(x+3)^2+5

interchanging role of x and y

x=(y+3)²+5

x-5=(y+3)²

√(x-3)-3=y

y=√(x-3)-3

:.inverse of f(x)=(x+3)^2+5 is f-¹(x)=√(x-3)-3

Answer:

MN = 4.5 ft

Step-by-step explanation:

Since the triangles are similar then the ratios of corresponding sides are equal, that is

[tex]\frac{MN}{JK}[/tex] = [tex]\frac{LN}{LK}[/tex] , substitute values

[tex]\frac{MN}{12}[/tex] = [tex]\frac{6}{16}[/tex] ( cross- multiply )

16MN = 72 ( divide both sides by 16 )

MN = 4.5 ft

Answer:

29

Step-by-step explanation:

The value of b by assuming that the two lines are parallel will be equal to 29°.

When two lines converge at a point, they produce an angle. The word "angle" refers to the length of the "gap" between these two rays. The symbol is used to denote it.

Radians, a unit of roundness or rotation, and degrees are the 2 most common units used to measure angles. In daily life, angles are present.

As per the given information provided by the given figure,

The angle is corresponding in nature,

So, the equation will be,

3b + 5 = 92

3b = 92 - 5

3b = 87

b = 87/3

b = 29°.

Therefore, the angle b is 29°.

Responder:

1176 Julios

Explicación paso a paso:

Como no se nos dice qué encontrar, podemos encontrar la energía potencial

PE = mgh

Dado

Masa m = 2 kg

g = 9,8 m / s ^ 2

h es la altura = 60 m

Sustituir

PE = 2 * 9,8 * 60

PE = 1176 Julios

Por lo tanto, la energía potencial del cuerpo es 1176 julios.

Step-by-step explanation:

3x + 7y = 17

1. 3(5) + 7(3) = 17 ---> 15 + 21 = 17 (false)

2. 3(-8) + 7(-2) = 17 ---> -27 + -14 = 17 (false)

3. 3(-6) + 7(5) = 17 ---> -18 + 35 17 (true)

4. 3(8) + 7(-1) = 17 ---> 18 + -7 = 11 (false)

(5, 3) and (-8, -2) are not solutions to the equation. (-6, 5) and (8, -1) are solutions to the equation.

To determine whether each ordered pair is a solution to the equation 3x + 7y = 17, we substitute the given x and y values into the equation and check if it holds true.

Let's evaluate each ordered pair:

(x, y) = (5, 3)

Substitute x = 5 and y = 3 into the equation:

3(5) + 7(3) = 15 + 21 = 36

36 ≠ 17

Therefore, (5, 3) is not a solution to the equation.

(x, y) = (-8, -2)

Substitute x = -8 and y = -2 into the equation:

3(-8) + 7(-2) = -24 - 14 = -38

-38 ≠ 17

Therefore, (-8, -2) is not a solution to the equation.

(x, y) = (-6, 5)

Substitute x = -6 and y = 5 into the equation:

3(-6) + 7(5) = -18 + 35 = 17

17 = 17

Therefore, (-6, 5) is a solution to the equation.

(x, y) = (8, -1)

Substitute x = 8 and y = -1 into the equation:

3(8) + 7(-1) = 24 - 7 = 17

17 = 17

Therefore, (8, -1) is a solution to the equation.

In summary:

(5, 3) and (-8, -2) are not solutions to the equation.

(-6, 5) and (8, -1) are solutions to the equation.

Step-by-step explanation:

−4−8v=−2(4v+2)

Step 1: Simplify both sides of the equation.

−4−8v=−2(4v+2)

−4+−8v=(−2)(4v)+(−2)(2)(Distribute)

−4+−8v=−8v+−4

−8v−4=−8v−4

Step 2: Add 8v to both sides.

−8v−4+8v=−8v−4+8v

−4=−4

Step 3: Add 4 to both sides.

−4+4=−4+4

Answer:

No solutions.

Step-by-step explanation:

We need to use PEMDAS to solve this problem, and as the first letter in PEMDAS stands for (parentheses) we should subtract 7 from 15 to get 8.

Secondly, we would multiply 2 by 8 to get 16.

Finally, we subtract 9 from 16 to get 7.

64 ≠ 7, so the answer would be no solutions.
