If she competed 10 miles in 45 minutes. Calculate her speed per second.

Answers

Answer 1

Answer:

Step-by-step explanation:

0.0037037045455 of a mile or 19.55556 feet per second

Answer 2

Answer: 1/270 miles per second

Step-by-step explanation:

Speed is equal to distance over time (s=d/t).

We can plug in 10 miles as distance, and 45 minutes as the time; however, you multiply the time by 60 since a minute has 60 seconds. The equation then becomes:

s=10/45*60

s=10/2700

s=1/270

Her speed is 1/270 mps.

Step by step :

x² = 12² + 10²

x² = 144 + 100

x² = 244

x = 15,6m✔

x² = 12² + 10²

x² = (12 × 12) + (10 × 10)

x² = 144 + 100

x² = 244

x = √244

x = 15,6 m

The length of a side of a square is 4x – 1.
Express the area of the square in terms of x.

Answers

Answer:

16x^2 - 8x + 1

Step-by-step explanation:

1. The area of a square can be represented as s^2 or (s)(s), where s = side.

2. (Solving)

Step 1: Set up expression

[tex](4x-1)^2[/tex] [tex](4x-1)(4x-1)[/tex]

Step 2: Apply the FOIL method (first, outside, inside, last)

[tex](4x)(4x)+(4x)(-1)+(-1)(4x)+(-1)(-1)[/tex] [tex]16x^2 -4x -4x +1[/tex]

Step 3: Simplify.

[tex](16x^2)+(-4x-4x)+(1)[/tex] [tex]16x^2 -8x + 1[/tex]

Therefore, the area of the square in terms of x is 16x^2 - 8x + 1.

Point V is on the line segment UW. Given VW=5x-4, UV=2x, and UW=5x, determine the numerical length of VW

Answers

So UV+VW=UW
Or 2x+5x-4=5x
So 7x-4=5x
This means that x is generally a low amount as x has to be less than 3 (as 3x7, 21-4=17 and 3x5=15.)
I then tried to input 2 and got 14-4=10 which is correct.
So x=2
We then input x=2 into 5x-4 for the answer.

5(2)-4

The final answer is 6

solve y

Answers

Answer:

x^2=8x-2x

x^2=6x

x^2/x=6x/x

x=6

y=2x ,2(6)

We should first simplify the right side, and doing so will get x/3+6=x/3+10. WE then subtract x/3 on both sides to get 6=10. Since this cannot be true, there are no solutions.

Answer:

no solution

Step-by-step explanation:

[tex]\frac{x}{3}[/tex] + 6 = 2([tex]\frac{x}{6}[/tex] + 5) ← distribute parenthesis by 2

[tex]\frac{x}{3}[/tex] + 6 = [tex]\frac{x}{3}[/tex] + 10 ( subtract 6 from both sides )

[tex]\frac{x}{3}[/tex] = [tex]\frac{x}{3}[/tex] + 4 ( subtract [tex]\frac{x}{3}[/tex] from both sides )

when 7 is added to 3 times a number, the sum is multiplied by 2 and 15 is subtracted what is the final answer

Answers

Answer:

2(3x+7) -15

Step-by-step explanation:

Let x = unknown number

7 is added to 3 times a number

3x+7

Multiply the sum by 2

2(3x+7)

Subtract 15

2(3x+7) -15

Answer:

Let the required number be " x "

Now, 7 is added to 3 times a number : (3x + 7)

Next, the sum is multiplied by 2 : 2(3x + 7)

And then, 15 is substracted from it : 2(3x + 7) - 15

2(3x + 7) - 15 is the final answer.
