IF the sum of four times a number and four less than three times a number is seventeen what is the number

Mathematics
1 answer:
Virty [35]2 years ago
3 0

Answer: 3

Step-by-step explanation: This equation can be written as 4x+3x-4=17

We can now solve.

Moving the 4 to the other side (adding) and we get 21.

Now we have 4x+3x. Adding like terms, we get 7x = 21. Now we divide by 7.

X = 3.

The blades of a windmill turn on an axis that is 35 feet above the ground. The blades are 10 feet long and complete two rotation
a_sh-v [17]

The correct option is (c) h = 10sin(π15t)+35.

The equations can be used to model h, the height in feet of the end of one blade, as a function of time, t, in seconds is  h = 10sin(π15t)+35.

<h3>How do windmills rotate?</h3>

The blades of a turbine, which resemble propellers and function much like an airplane wing, capture the wind's energy.

A pocket of low-pressure air develops on one side of the blade when the wind blows. The blade is subsequently drawn toward the low-pressure air pocket, which turns the rotor.

Calculation for the equation of the model height-

Let's now review each choice individually and select the best one.

The blade is horizontal at time t = 0. As a result, h = 35 at t = 0 is valid for all of the possibilities in this situation.

They accomplish two spins in a minute. The blades will so complete one rotation in 30 seconds. and they will complete a quarter rotation in 15/2 seconds. Because of this, the blade will be vertically up from time t = 0 to t = 15/2. Its height in this instance should be 35 + 10 = 45 ft. Let's now examine the available possibilities.

If we put t=15/2 in the options

Option (a) gives h = 25

Option (b) gives h = -10sin(15/2) + 35

Option (c) gives h = 45

Option (d) gives h = 10sin(15/2) + 35

Therefore, the correct equation is given in option c.

The complete question is -

The blades of a windmill turn on an axis that is 35 feet above the ground. The blades are 10 feet long and complete two rotations every minute. Which of the following equations can be used to model h, the height in feet of the end of one blade, as a function of time, t, in seconds? Assume that the blade is pointing to the right, parallel to the ground at t = 0 seconds, and that the windmill turns counterclockwise at a constant rate.

a) h = −10sin(π15t)+35  

b) h = −10sin(πt)+35

c) h = 10sin(π15t)+35

d) h = 10sin(πt)+35

At least pet snake is 42 inches long and Royals pet snake is 8 feet long.How many inches longer is Royals snake
Ostrovityanka [42]

Answer:

54 inches

Step-by-step explanation:

At least pet snake is 42 inches long and Royals pet snake is 8 feet long.How many inches longer is Royals snake

Step 1

We would be converting the length of the Royal's pet snake to inches

1 foot = 12 inches

8 feet = x

Cross Multiply

x = 8 × 12 inches

x = 96 inches

Step 2

How many inches longer is Royal's snake?

This is calculated by subtracting the length of the Royal's pet snake from the least length

= 96 inches - 42 inches

= 54 inches

Therefore, the Royal's snake is 54 inches longer
