Find the value of x to the nearest tenth.

Find The Value Of X To The Nearest Tenth.

Answers

Answer 1
Answer:

x = 7.8

Step-by-step explanation:

a^2 + b^2 = c^2

4^2 + 2^2 = c^2

16 + 4 = c^2

c^2 = 20

c = 4.5

a^2 + b^2 = c^2

a^2 + 4.5^2 = 9^2

a^2 + 20.25 = 81

a^2 = 81 - 20.25

a^2 = 60.75

a = 7.8

Answer 2

Answer:

Step-by-step explanation:

Using Pythagoreus Theorem

In the smaller rectangle

2²+4² = h²

20 = h²

h = √20

h = 2√5

Therefore two sides of the rectangle will 2√5

No using pythagoreus theorem in the bigger triangle

x² + (2√5)² = 9²

x² = 9² - (2√5)²

x² = 81 - 20

x = √61

x = 7.8102496759

When rounded off to nearest tenth the hundreth digit is in 0-5 range

x = 7.81

Josh biked to the park at an average speed of 14 mph. He returned home at an average speed of 10 mph. If Josh spent a total of 2 1/2 hours for the roundtrip, how many total miles did he bike?

Answers

Answer:

Let the distance from home to the park be x

Going to the park

Distance=vt

x=14t¹ ——(1)

Going back home

x=10t² ——(2)

Total time=t¹+t²

2.5=t¹+t²

Solving equ. 1 and 2 simultaneously

10x=140t¹

14x=140t²

Adding

4x=140(t¹+t²)

24x=140(2.5)

x=14.58 miles

Total distance= 2x

= 29.16miles

Select the correct answer. If x and y are positive real numbers, which expression is equivalent to the expression below? (125x^4y3/2)1/3÷(xy)1/2

Answers

Answer:

5x^(5/6)

Step-by-step explanation:

we will use properties of exponents

x^a/x^b = x^(a-b)

and

x^a * x^b = x^(a+b)

___________________________________

(125x^4y3/2)1/3÷(xy)1/2\\

expanding each term by taking power for each component of expression

=>125^(1/3) x^(4/3) y(3/2*1/3) ÷ x(1/2)y(1/2)

=>5*x^(4/3) y(1/2) ÷ x(1/2)y(1/2)

using property =   x^a/x^b = x^(a-b)

=>5x^(4/3 - 1/2) y^(1/2 -1/2)

y^(0) = 1

=> 5x^((4*2-3)/3*2) *1

=> 5x^(5/6)

Thus, value of expression is 5x^(5/6)

An air traffic controller is tracking two planes. To start, Plane A is at an altitude of 3028 feet and Plane B is at an altitude of 4000 feet. Plane A is gaining altitude at 55.75 feet per second and Plane B is gaining altitude at 35.5 feet per second. How many seconds will pass before the planes are at the same altitude? seconds What will their altitude be when they're at the same altitude? feet

Answers

Consider plane A with respect to B,

initial relative Altitude [tex] h_{a, b}=h_a-h_b=-972 [/tex]

relative rate of altitude(speed) $r_{a,b}= 55.75-35.5=20.25$

To get at same altitude, they'll take same time, and their relative height will be $0$ So,

$H_{a,b}=h_{a,b}+r_{a,b}t$

$0=-972+20.25t$

$t=48$

and altitude will be, $3028+55.75\cdot 48=5704$

Answer:

48 seconds5704 feet

Step-by-step explanation:

We can write equations for the altitude of each plane:

  A(t) = 3028 +55.75t . . . . . initially at 3028 ft; gaining at 55.75 ft/s

  B(t) = 4000 +35.5t . . . . . initially at 4000 ft; gaining at 35.5 ft/s

The two altitudes will be equal when ...

  A(t) = B(t)

  3028 +55.75t = 4000 +35.5t . . . . substitute the expressions for A and B

  20.25t = 972 . . . . . . subtract 3028+35.5t

  t = 48 . . . . . . . . . . . . divide by 20.25

The common altitude will be ...

  B(48) = 4000 +35.5(48) = 5704 . . . . feet

The planes will both be at an altitude of 5704 feet after 48 seconds.

.The conversion of square feet to square yards can be represented by direct variation. Three square yards are equivalent to 27 square feet. Let y represent the number of square yards and x the number of square feet. Then y varies directly with x.

What is the constant of variation?



What is the equation representing the direct variation?

Answers

Answer:

The constant of variation is 1/9

The equation representing the direct variation is y/x= 1/9

Step-by-step explanation:

In direct variation, y/x=k denotes the equation, with k being the constant of variation. Here, y is the number of square yards and x is the number of square feet. Therefore, as we know that 27 square feet = 3 square yards, we can write one point (x₁, y₁) as (27 square feet, 3 square yards). Plugging x₁ and y₁ into our equation, we get

y/x = k

3 / 27 = k

(3/27) / (3/3) = 1/9* = k

Therefore, the constant of variation is 1/9

Next, as stated previously, y/x = k represents the equation of direct variation. Therefore, y / x = 1/9 as our equation

* because 3 is a factor of both 3 and 27, we can divide both the numerator and denominator by 3 to keep the fraction the same but also simplify it. One way to find the greatest common factor is to list the factors of each number and see the highest number that is a factor of both

The constant of variation is "1/9" and the equation representing the direct variation is y = (1/9)x.

What is the equation?

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

The equation of direct variation is given by,

y = kx   ....(i)    where "k" is a constant.

Let y represent the number of square yards and x the number of square feet. Then y varies directly with x.

Given that y varies directly with x, and x = 27, then y = 3.

Substitute the values of y = 3 and x = 27 in the direct variation equation and solve for k:

⇒ 3 = 27k

⇒ k = 3/27

⇒ k = 1/9

Substitute the values of k = 1/9 in the direct variation equation :

⇒ y = (1/9)x

Thus, the constant of variation is "1/9" and the equation representing the direct variation is y = (1/9)x.

Answer:

The lines DE and BC have the same slope, therefore the two lines, DE and BC, are parallel

Step-by-step explanation:

To prove that DE is parallel to BC, we have;

The slope, m of the lines DE and BC are found from the following equation;

[tex]Slope, \, m =\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

Where;

(x₁, y₁) and (x₂, y₂) = (b, c) and (a + b + c) for DE, we have;

[tex]Slope, \, m =\dfrac{c - c}{a + b-b} = 0[/tex]

Where we have (x₁, y₁) and (x₂, y₂) = (0, 0) and (2a, 0) for BC, we have;

[tex]Slope, \, m =\dfrac{0 - 0}{2a-0} = 0[/tex]

Therefore, because the lines DE and BC have the same slope, the two lines DE and BC are parallel.
