I need it help to find which statement is true ASAP!

Answer:

Walking speeds vary depending on age, and health of walkers. However, an average comfortable walking speed is about 5 km per hour and 9km per hour can be achieved by many people. This means that in 30 minutes it should be possible to easily walk 2.5km and in 2 hours it should be possible to walk 10km.

Answer:

0.07929 km/min

Step-by-step explanation:

1 miles is 1.903 km

5 miles is 9.515 km in 2 hours

9.515 /2 = 4.7575 km/h

Then divide th speed value by 60

4.7575 / 60 = 0.07929

Answer:

1,000,000.

Step-by-step explanation:

You are rounding to the nearest hundred thousand place value, which will be underlined and bolded:

982,510

Note that when you round, you look at the digit directly next to the place value you are solving for. Note:

If the value of the digit is 5 or greater, round up.

If the value of the digit is 4 or less, round down.

In this case, the value directly next to the place value is the ten thousands place, which has the value of 8. Because 8 is greater than 5, you will round up.

982510 rounded to the nearest hundred thousand is 1,000,000.

(a)

Given:

72 to be split into 1:3:5

Solution:

First divide the amount with the sum of the ratio given

72 / 1 + 3 + 5 = 72 / 9 = 8

Now multiply the answer with each value:-

8 × 1 = 8

8 × 3 = 24

8 × 5 = 40

∴ The ratio will be 8:24:40

{To check your answer add to get the exact value: 8 + 24 + 40 = 72}

(b)

Given:

150 to be split into 2:3

Solution:

First divide the amount with the sum of the ratio given

150 / 2 + 3 = 150 / 5 = 30

Now multiply the answer with each value:-

30 × 2 = 60

30 × 3 = 90

∴ The ratio will be 60:90

{Now check your answer in the same way above: 60 + 90 = 150}

Step-by-step explanation:

In order to find the focus of a parabola, you must know that the equation of a parabola in a vertex form is y=a(x−h)2+k where a represents the slope of the equation. From the formula, we can see that the coordinates for the focus of the parabola is (h, k+1/4a).

Answer:

Option B is correct

Step-by-step explanation:

Let the number be x

Second number = x + 1

Sum = 85

x + x + 1 = 85

2x + 1 = 85

2x = 85 - 1

2x = 84

x = 84/2 = 42

Numbers are 42 and 43

Answer:

B) x+(x+1)=85

Step-by-step explanation:

Consecutive means in a row

Let x be the first integer

x+1 is the next integer

x+x+1 = 85

One leg        = 5

other leg =      x            Substitute into a^2 + b^2 = c^2

x ^2 + 5^2 = 12^2

x^2 + 25 = 144              Subtract 25 from both sides

x^2 = 144 - 25              Combine

x^2 = 119                      Take the square root of both sides

x = sqrt(119)

Answer:

x = 4

Step-by-step explanation:

Start by setting the two expressions equal to each other, since they're the same height.

6 + 15x = 6x + 42

Subtract 6x from both sides

6 + 9x = 42

Subtract 6 from both sides

9x = 36

Divide both sides by 9

x = 4

An equation is formed of two equal expressions. The value of x is 4.

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

Given that the height of Ashton and James are the same height. Also, Ashton's height is represented by (6 + 15x) and James's height is represented by (6x + 42). Therefore, we can write,

Ashton's height = James' height

6 + 15x = 6x + 42

6 + 15x = 6x + 42

15x - 6x = 42 - 6

9x = 36

x = 36/9

x = 4

Hence, the value of x is 4.

Answer:

The remainder is 11.

Step-by-step explanation:

We are given the polynomial:

[tex]f(x) = x^3 + x^2 - 9x + 23[/tex]

And we want to find its remainder when the polynomial is divided by:

[tex]x + 4[/tex]

We can use the Polynomial Remainder Theorem. According to the PRT, if we divide a polynomial P(x) by a binomial in the form (x - a), the remainder will be given by P(a).

In this case, our binomial is (x + 4) or (x - (-4)). Hence, a = -4.

Then the remainder will be f(-4):

[tex]\displaystyle \begin{aligned}f(-4) &= (-4)^3 + (-4)^2 - 9(-4) + 23 \\ &= 11 \end{aligned}[/tex]

In conclusion, the remainder of the operation is 11.
