Answer:

Step-by-step explanation:

Given the frequency vibrations for a certain guitar string modeled by the equation

F = 200√T where:

T is amount of tantrums in pounds

If the frequency of the vibrations is 600 vibrations per second, the amount of pounds in tantrums will be gotten by substituting F = 600 into the equation and calculating T as shown:

600 = 200√T

Divide both sides by 200

600/200 = 200√T /200

3 = √T

Square both sides

3² = (√T)²

9 = T

T = 9

Hence 9 pounds of tantrum was used to plug the string

Step-by-step explanation:

[∛27]∧-2

We first slove for the bracket before the outer bracket

[∛27]∧-2

Where ∛27 = 3

Answer:

It would take him 8 hours

Since every 50 miles takes 1 hour

━━━━━━━☆☆━━━━━━━

▹ Answer

8 Hours

▹ Step-by-Step Explanation

First, find the unit rate:

100 miles ÷ 2 hours = 50 mph

Now, we need to find the time it takes to drive 400 miles so we will divide:

400 miles ÷ 50 mph = 8 hours

If you are looking for total hours, you would add:

2 hours + 8 hours = 10 hours

If you are looking for how long it'll take to drive the 400 miles, it would just remain 8.

Hope this helps!

Answer:

what

Step-by-step explanation:

Answer:

23. y = 47

Step-by-step explanation:

40 + 5x =180 (angls on a straight line add up to 180 degrees)

5x=140 (minus 40 from both sides)

x = 28 (divide both sides by 5)

3y - 1 = 140

3y =141 (add 1 to both sides)

y = 47 (divide both sides by 3)

Answer:

y=47

Step-by-step explanation:

Answer:

y=-6x+36

Step-by-step explanation:

у + 6x — 36 = 0

-add 36 to both sides

y+6x=36

-subtract 6x from both sides

y=36-6x or y=-6x+36

-This should be the correct answer

Sum of two angles that are supplementary = 180°

Then :-

[tex]3x - 2 + 2x+ 7 = 180[/tex]

[tex]5x + 5 = 180[/tex]

[tex]5x = 180 - 5[/tex]

[tex]5x = 180 - 5[/tex]

[tex]5x = 175[/tex]

[tex]x = \frac{175}{5} [/tex]

[tex]x = 35[/tex]

Which means :-

The measure of the larger angle :-

= 35 × 3 - 2

= 105 - 2

= 103°

The measure of the smaller angle :-

= 2 × 35 + 7

= 70 + 7

Therefore , the value of x = 35 and the measure of the smaller angle = 77° .

Answer:

(w + 3) [7w²  - 3]

Step-by-step explanation:

Given expression:

    7w²(w + 3) - 3(w + 3);

 Now rewriting the equation by factoring out (w+ 3);

 Solution:

   7w²(w + 3) - 3(w + 3);

   = (w + 3) [7w²  - 3]

The solution is (w + 3) [7w²  - 3]

Answer:

56 students

Step-by-step explanation:

The equation for your question is 85+2x=197. First you would have to subtract 85, on both sides, leaving you with 2x=112. Then, you'd have to divide by 2 on both sides to isolate the variable. From there, you're left with x=56.

Answer:

Because it is 2 of the same number.

Step-by-step explanation:

The vertex is S. The angle can only be measured from point S.

An equation is formed of two equal expressions. n=2m can be proved by solving the two of the given equation for h and then equating them together as shown below.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

Given the two equations, 2n=m+h, and h=n+m. Now, solve the two of the equations for h as shown below.

Equation 1.

2n = m + h

2n - m = h

h = 2n - m

Equation 2.

h = n + m

Further, equate the value of h from both the equation,

h = h

2n - m = n + m

Bring the like terms on the same side of the equation,

2n - n = m + m

n = 2m

Hence, proved n=2m.

Answer:

the two numbers are 31 and 32.

Step-by-step explanation:

x+(x+1)=63

2x+1=63

2x=62

x=31

The answers are 31 and 32

The sum of two consecutive numbers is 63. Consecutive numbers are numbers that are in a row (e.g. 1, 2, and 3 are consecutive integers). This means we can represent the two consecutive numbers with x and x+1. Plugging the numbers back into the equation, you get

x + x+1 = 63

Simpifying, you get

2x+1 = 63

Now, you just need to isolate x. To do this, you should subtract 1 from both sides, making the equation.

2x=62

Lastly, you need to divide both sides by 2, making making the equation

x=31

The two integers are x and x+1, and when you plug 31 into that, the numbers are 31 and 32.

4/9 is the answer
