a boat can travel 176 kilometers on 88 liters of gasoline. How much gasoline will it need to go 250 kilometers

Answer:

Yes, they are.

Step-by-step explanation:

Lets simplify both rates to the rate typer per minute.

(m is minutes)

3m = 96

Divide both sides by 3:

[tex]\frac{3m}{3} = \frac{96}{3}[/tex]

m = 32

So the rate is 32 words per minute.

5m = 160

Divide both sides by 5:

[tex]\frac{5m}{5} = \frac{160}{5}[/tex]

m = 32

Answer:

h =  2A / (b1 + b2)

Step-by-step explanation:

A = 1/2h (b1 + b2)

Divide both sides by 1/2 (b1 + b2)

h  =  A / 1/2 (b1 + b2)

h =  2A / (b1 + b2)

Answer:

2A /  (b1+b2)  = h

Step-by-step explanation:

The formula for the area of a trapezoid is

A = 1/2 (b1+b2) *h

We want to solve for h

Multiply each side by 2

2A = 2*1/2  (b1+b2) *h

2A =  (b1+b2) *h

Divide each side by  (b1+b2)

2A /  (b1+b2)  =  (b1+b2) / (b1+b2) *h

2A /  (b1+b2)  = h

The top-left graph is the correct representation of the function[tex]\( f(x) = 0.75^x \)[/tex]. It shows a decreasing function as [tex]\( x \)[/tex] increases, and the y-intercept is at (0, 1).

The correct option is (A).

To determine which graph represents the function [tex]\( f(x) = 0.75^x \)[/tex], we should consider the key characteristics of an exponential function where the base is between 0 and 1:

1. As [tex]\( x \)[/tex]  increases, [tex]\( f(x) \)[/tex] should decrease because 0.75 raised to a higher power becomes smaller.

2. As [tex]\( x \)[/tex] decreases (becomes more negative), [tex]\( f(x) \)[/tex] should increase because 0.75 raised to a negative power becomes larger.

3. The graph will never touch the x-axis, as an exponential function does not cross the axis when the base is positive.

4. The y-intercept should be at [tex]\( f(0) = 0.75^0 = 1 \)[/tex] because any non-zero number to the power of 0 is 1.

Now let's evaluate the provided graphs with respect to these characteristics:

- Top-left graph:This graph shows a decreasing function as [tex]\( x \)[/tex] increases, and the y-intercept is at (0, 1), which matches the behavior of [tex]\( f(x) = 0.75^x \)[/tex].

- Top-right graph:This graph increases as [tex]\( x \)[/tex] increases, which is not correct for [tex]\( f(x) = 0.75^x \)[/tex].

- Bottom-left graph:This graph also increases as [tex]\( x \)[/tex] increases, which does not match the expected behavior.

- Bottom-right graph:This graph shows a decreasing function as [tex]\( x \)[/tex]increases, but the y-intercept is not at (0, 1), so it does not represent [tex]\( f(x) = 0.75^x \)[/tex].

Based on this analysis, the top-left graph is the correct representation of the function[tex]\( f(x) = 0.75^x \)[/tex]. It shows a decreasing function as [tex]\( x \)[/tex] increases, and the y-intercept is at (0, 1).

complete question given below:

Which graph represents the function f(x) =0.75^x

Answer:

x = 2

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y-intercept )

here m = - [tex]\frac{7}{2}[/tex] and c = 12

y = - [tex]\frac{7}{2}[/tex] x + 12 ← equation in slope-intercept form

given (x, 5) lies on the line, solve for x by letting y = 5

- [tex]\frac{7}{2}[/tex] x +12 = 5

multiply all terms  by 2 to eliminate the fraction

- 7x + 24 = 10 ( subtract 24 from both sides )

- 7x = - 14 ( divide both sides by - 7 )

x = 2

Answer:

It is given that,  

there are 8 balls in the bag numbered 1 to 8

5 balls are  color is gray and all others are white

The gray color balls are 2,3,4,5 and 7

The white color balls are 1,6 and 8

P(X) = probability of getting white ball

P(not X) = Probability of getting gray ball

a) To find Probabilities P(X) and P(not X)

For event X, 1,,6,8 are checked and P(X) = 3/8

for event 'not X' 2,3,4,5 and 7 are checked and P(not X ) = 5/8

b) To find 1 - P(X)

1 - P(X) = 1 - 3/8 = (8 - 5)/8 = 5/8  

c)1 - P(X) is same as P(not X)

Find the expression.

Let the number be M.

"Nine more than twice a number is less than negative nineteen".

We can write this statement as:

2M + 9 < -19

Find the number M.

2M + 9 < -19

2M < -19 - 9

2M < -28

M < -28/2

M < -14

Let us check the statement is true with M < -14.

2M + 9 < -19

2 x -15 + 9 = -19

-30 + 9 = -19

-21 < -19

This is true.

We see that all numbers below -14 will make the statement true.

So,

The numbers are -15, -16, -17, -18,..........-∞

Thus the numbers that make the statement true are ( -14, -∞ ) or [-15, -∞).

To solve the inequality, we need to translate the given statement into an algebraic expression and then solve for 'x' using subtraction and division.

To solve the inequality, we will translate the given statement into an algebraic expression. Let's say the number is represented by 'x'. 'Twice a number' can be written as 2x. 'Nine more than twice a number' can be written as 2x + 9.

So, the inequality becomes 2x + 9 < -19.

To solve for 'x', we subtract 9 from both sides of the inequality, giving us 2x < -28. Then, we divide both sides by 2, resulting in x < -14.

Therefore, any number less than -14 will make the statement true.

Answer:

The 3rd equation on the left column  and second one on the right column.

Step-by-step explanation:

These 2 equations have same  coefficients of x and y if we divide the first one by 4 and the second by 2.

This gives the 2 equations

x^2 + y^2 - 4x + 6y - 7 = 0

x^2 + y^2 - 4x + 6y - 20 = 0

If we compete the square on these we get

(x - 2)^2 + (y + 3)^2 =  20

(x - 2(^2 + (y + 3)^2 =  33

These are in standard form . The center is the same (2, -3) but the radii are different so they are concentric.

In mathematics, concentric circles have the same center but different radii. Their general equation is (x-h)²+ (y-k)² = r², sharing the same (h, k) coordinates. Examples include equations like (x - 2)² + (y - 3)² = 4 and (x - 2)² + (y - 3)² = 9.

In mathematics, concentric circles are circles that share the same center but have different radii. The general equation of a circle is given by (x - h)² + (y - k)² = r², where (h, k) is the center and r is the radius. Two such equations will represent concentric circles if and only if their center coordinates (h, k) are the same.

For example, consider the equations:

(x - 2)² + (y - 3)² = 4

(x - 2)² + (y - 3)² = 9

Both these circles have the center at (2, 3) but different radii (2 and 3 respectively), making them concentric circles.

Answer:

x=34

Step-by-step explanation:

Please, see the attached file.

Thanks.

Answer:

Hence final answer is x=34

Step-by-step explanation:

∠ADC= ∠EDF {Vertically opposite angles are always equal}

∠ADC= 36°  {Given }

∠ADB= 36°...(i)  {Same angles}

∠ABI + ∠ABC = 180° {supplementry angles }

113° + ∠ABC = 180°  {Given }

∠ABC = 180° - 113°

∠ABC = 67°

∠ABD = 67° ...(ii)  {same angle}

We know that sum of all three angles of triangle is 180 degree so we can write:

∠ABD + ∠ADB + ∠BAD =  180°

67° + 36° + ∠BAD =  180°  {using (i) and (ii) }

67° + 36° + x°+43° =  180°  {from diagram }

146° + x° =  180°

x° =  180° - 146°

x° =  34°

Hence final answer is x=34

Answer:

We can translate Circle C (x+6, y-2) to have the same center as D. The ratio of radius to radius is 10/5=2. Scale factor 2 from C to D.

Step-by-step explanation:

Similar objects are objects which are the same shape but not the same size. This means they have the same angle measures and a scale factor between the side lengths. To show similarity, we can use transformations and proportions. We can translate to shift the object, dilation to increase or decrease size and so forth. We use proportions to find scsale factor or missing length.

We have a circle. Circles do not have a specific angles and all circles have 360 degrees. They do not have sides but do have radius. All circles are similar because all are the same shape - a fixed center with points equidistant from the center (the radius). To show similar we can translate the circle so the centers are the same and create a ratio between the radius.

We can translate Circle C (x+6, y-2) to have the same center as D. The ratio of radius to radius is 10/5=2. Scale factor 2 from C to D.

Answer:

44   You will get the 2x and 88 and divide 88 by 2x

Step-by-step explanation:

Answer:  The required value of x is 22.

Step-by-step explanation:  Given that B and F are the midpoints of the sides AC and AE of triangle ACE.

Also, BF = 2x  and  CE = 88.

We are to find the value of x.

Midpoint theorem :  If a line segment joins the midpoints of any two sides of a triangle, then it is parallel to the third side and its length is equal to half of the length of the third side.

From triangle ACE, we have

B and F are the midpoints of the sides Ac and AE respectively, so BF will be parallel to CE and its length will ne half of the length of side CE.

Therefore,

[tex]BF=\dfrac{1}{2}\times CE\\\\\Rightarrow 2x=\dfrac{1}{2}\times88\\\\\Rightarrow 2x=44\\\\\Rightarrow x=\dfrac{44}{2}\\\\\Rightarrow x=22.[/tex]

Thus, the required value of x is 22.

To find the percent of change from 500,000 to 10,000, subtract 10,000 from 500,000 to get 490,000, then divide that difference by the original number and multiply by 100 to get the percentage.

To find the percent of change from 500,000 to 10,000, we need to calculate the difference between the two numbers and then find the percentage of that difference relative to the original number.

Step 1: Find the difference: 500,000 - 10,000 = 490,000.

Step 2: Find the percent: (490,000/500,000) × 100 = 98%.

The percent of change from 500,000 to 10,000 is 98%.

Step-by-step explanation:

I'm pretty sure that D is the answer. It jut basically moved , didn't change anything.

Answer:

1. The equation of line is [tex]y=-\frac{1}{2}(x)+1[/tex].

2. The correct option is D.

Step-by-step explanation:

1.

The slope intercept form of a line is

[tex]y=mx+b[/tex]

Where, m is slope and b is y-intercept.

The given equation of a line is

[tex]y=2x+8[/tex]

The slope of line is 2 and y-intercept is 8.

The product of slopes of two perpendicular lines is -1.

[tex]m_1\times m_2=-1[/tex]

[tex]2\times m_2=-1[/tex]

[tex]m_2=-\frac{1}{2}[/tex]

The slope of required line is [tex]-\frac{1}{2}[/tex] and it passes through the point (6,-2).

The equation of required line is

[tex]y-y_1=m(x-x_1)[/tex]

[tex]y+2=-\frac{1}{2}(x-6)[/tex]

[tex]y+2=-\frac{1}{2}(x)+3[/tex]

[tex]y=-\frac{1}{2}(x)+3-2[/tex]

[tex]y=-\frac{1}{2}(x)+1[/tex]

Therefore the equation of line is [tex]y=-\frac{1}{2}(x)+1[/tex].

2.

Translation is a rigid transformation. It means if a figure translated then the image and preimage are congruent

It the given figure two triangles are congruent because a translation does not change size and shape.

Therefore the correct option is D.

b + a = 14

b = 14 - a

14 - a + a = 14

14 = 14

Since we can't gain any further information after solving for b the first time, we know b = 14 - a to be the simplest form of b.
