Mike's slower rate of driving across country was 65 mph.

Let the slower rate be represented as r mph. The faster rate will be r+10 mph. The total distance covered (495 miles) is the product of the time and the rate:

Adding up the distances, we get:

Simplifying the equation:

Combining like terms:

Subtracting 40 from both sides:

Dividing by 7:

Therefore, the slower rate is 65 mph.

https://brainly.com/question/30164170

#SPJ11

The correct answer for the slower rate at which Mike drove is 65 mph.

To find the slower rate at which Mike drove, let's denote the slower rate as r mph. Mike drove at this rate for 3 hours. He then drove for 4 hours at a rate that is 10 mph faster than the slower rate, which would be r + 10 mph.

The total distance covered by Mike is the sum of the distances covered at each rate. We can set up an equation to represent this:

[tex]\[ 3r + 4(r + 10) = 495 \][/tex]

Expanding the equation, we get:

[tex]\[ 3r + 4r + 40 = 495 \][/tex]

Combining like terms, we have:

[tex]\[ 7r + 40 = 495 \][/tex]

Now, we need to solve for r We can do this by subtracting 40 from both sides of the equation:

[tex]\[ 7r = 495 - 40 \] \[ 7r = 455 \][/tex]

Dividing both sides by 7 to solve for r, we get:

[tex]\[ r = \frac{455}{7} \] \[ r = 65 \][/tex]

Therefore, the slower rate at which Mike drove is 65 mph.

Answer:

No, because they do not have the same area.

Step-by-step explanation:

For the piece of paper to cover once without overlap or gaps, it must have the same area as the the total surface area of the prism.

The total surface area of the rectangular prism is: [tex]2(3.5\times2+3.5\times1.5+2\times1.5)=30\frac{1}{2}in^2[/tex]

Answer:

# Answer B is true ⇒ KL = 2(JL)

# Answer C is true ⇒ JK = √3(JL)

# Answer F is true ⇒ JK = √3/2(KL)

Step-by-step explanation:

* Lets explain the ratio between the sides of the triangle

- In Δ JKL

∵ The measure of angle J is 90°

∴ KL is the hypotenuse

∵ The measure of angle K is 30°

∴ JL is the opposite side to angle 30°

∵ The measure of angle L is 60°

∴ JK is the opposite side to the angle 60°

- There is a fact in the triangle which has angles 30° , 60° , 90°

# The length of the side opposite to the angle of measure 30° is

  half the length of the hypotenuse

∵ KL is the hypotenuse

∵ JL is the opposite side to the angle of measure 30°

∴ JL = 1/2 KL  OR KL = 2 JL

# The length of the side opposite to the angle of measure 60° is

  √3 the length of the opposite side to the angle 30°

∵ JK is the opposite side to the angle of measure 60°

∵ JL is the opposite side to the angle of measure 30°

∴ JK = √3 JL

# The length of the side opposite to the angle of measure 60° is also

  half √3 the length of the hypotenuse

∵ JK is the opposite side to the angle of measure 60°

∵ KL is the hypotenuse

∴ JK = √3/2 KL

- From the relation above

# Answer B is true ⇒ KL = 2(JL)

# Answer C is true ⇒ JK = √3(JL)

# Answer F is true ⇒ JK = √3/2(KL)

Answer:

Length 34 cm

Width 8 cm

Step-by-step explanation:

Let

x-----> the length of the rectangle

y----> the width of the rectangle

we know that

The perimeter of rectangle is equal to

P=2(x+y)

P=84 cm

so

84=2(x+y)

42=x+y ----> equation A

x=4y+2 -----> equation B

substitute equation B in equation A and solve for y

42=(4y+2)+y

5y=42-2

y=40/5=8 cm

Find the value of x

x=4y+2 ----> x=4(8)+2=34 cm

The dimensions are

Length 34 cm

Width 8 cm

The width of the rectangle is 8 cm and the length is 34 cm.

To determine the dimensions of the rectangle, we need to set up equations based on the given information.

Let's denote the width of the rectangle by W (in cm). According to the problem, the length L is 2 cm more than four times the width. Therefore, we can express the length as:

L = 4W + 2

The perimeter of a rectangle is calculated using the formula:

Perimeter = 2L + 2W

Given that the perimeter is 84 cm, we can substitute the expressions for L and W into the perimeter formula:

84 = 2(4W + 2) + 2W

Simplify the equation:

Now that we have the width, we can find the length:

L = 4(8) + 2 = 32 + 2 = 34

Thus, the dimensions of the rectangle are:

Answer:

2 and -10

Step-by-step explanation:

let the two integers be x and y.

so, x+y=-8---‐-------(1)

and,

x=y+12-------‐-----(2)

from (1) and (2),

(y+12)+y=-8

or, 2y=-8-12

or, y=-20/2

or, y=-10

substitutting the value of y in (2),

x=-10+12=2

therefore the required integers are 2 and -10.

Answer:

-20

Step-by-step explanation:

→ The sum of two integers is -8.

⇒ One will be called "x" and the other will be called "y"

→ One integer is 12 ( "y" )

Let's set up an equation x = ? and y = 12 so,

→ x + y = -8

( Substitute y for 12 )

→ x + 12 = -8

( -12 from both sides to isolate x )

→ x = -20

Final answer:

Barry is currently 13 years old and his sister is 5 years old. This is determined by setting up a system of equations based on the given information and solving for their current ages.

Explanation:

The question involves solving a system of equations to find the current ages of Barry and his sister. Let's let B represent Barry's current age and S represent his sister's current age. According to the problem, Barry is 8 years older than his sister (B = S + 8). In 3 years, Barry will be twice as old as his sister will be then (B + 3 = 2(S + 3)).

Write down the two equations: B = S + 8 and B + 3 = 2(S + 3).

Substitute B from the first equation into the second equation: (S + 8) + 3 = 2(S + 3).

Simplify and solve for S: S + 11 = 2S + 6.

Rearrange the equation to find S: S = 5.

Substitute the value of S back into the first equation to find B: B = 5 + 8, so B = 13.

Therefore, Barry is currently 13 years old and his sister is 5 years old.

Answer:

800 meters

Step-by-step explanation:

y is inversely proportional to x is the same as y is inversely proportional to [tex]\frac{1}{x},[/tex] that means

[tex]y=\dfrac{k}{x}.[/tex]

If a wave with a frequency of x=720 kilohertz has a length of y=500 meters, then

[tex]500=\dfrac{k}{720}\\ \\k=500\cdot 720=360000.[/tex]

Hence, the length of a wave y with a frequency of x=450 kilohertz is

[tex]y=\dfrac{360000}{450}=800[/tex]

The relationship between the frequency and wavelength of a wave is given by the formula:
\[ c = f \times \lambda \]
where:
- \( c \) is the speed of light (or the speed of the wave in another medium, but for radio waves in the air or vacuum, it's approximately the speed of light),
- \( f \) is the frequency of the wave,
- \( \lambda \) is the wavelength of the wave.
Given that the relationship is inverse, when the frequency goes up, the wavelength goes down, and vice versa.
We are given that a wave with frequency 720 kilohertz has a length of 500 meters. We can represent this with the equation:
\[ c = 720 \times 500 \]
We are asked to find the wavelength when the frequency is 450 kilohertz. Since the speed of light doesn't change, we set up the proportion using the formula, keeping \( c \) constant:
\[ 720 \times 500 = 450 \times \lambda_{\text{new}} \]
Now we solve for \( \lambda_{\text{new}} \):
\[ \lambda_{\text{new}} = \frac{720 \times 500}{450} \]
To simplify this, we can divide both the numerator and the denominator by a common factor. In this case, let's divide by 90:
\[ 720 \div 90 = 8 \]
\[ 450 \div 90 = 5 \]
\[ 500 \text{ remains unchanged} \]
Now we can substitute these simplified numbers back into our equation:
\[ \lambda_{\text{new}} = \frac{8 \times 500}{5} \]
\[ \lambda_{\text{new}} = \frac{4000}{5} \]
\[ \lambda_{\text{new}} = 800 \]
So the length of a wave with a frequency of 450 kilohertz is 800 meters.
