Answer:

where is the graph

Step-by-step explanation:

Answer:

68

Step-by-step explanation:

Let:

Number of girls invited = x

Number of boys = x +20

3/4 of boy showed up

2/3 of girls showed up

Exactly 19 did not show up

Therefore, we could say:

Fraction of boys that didn't show up = 1 - 3/4 = 1/4

Fraction of girls that didn't show up = 1 - 2/3 = 1/3

That is,

[1/4 *(x + 20)] + [1/3*x] = 19

[(x + 20) / 4] + x /3 = 19

(3(x + 20) + 4x) / 12 = 19

3x + 60 + 4x = 228

7x = 228 - 60

7x = 168

x = 168 / 7

x = 24

Number of girls, x = 24

Number of boys, x + 20 = 24 + 20 = 44

Total friends invited = (24 + 44) = 68

Answer:

2x-15+10x-25=180

2x-10x=180+15+25

-5x=220

=44

Answer:

f(x)=-2x+5

Step-by-step explanation:

The line shown in the graph is always decreasing at a constant rate, has a slope of -2, and has a y-intercept of 5.

So the parent function has been reflected across the x-axis (multiplied by -1), vertically stretched by a factor of 2 (multiplied by 2), and vertically translated up 5 units (5 added to it).

Therefore, the slope-intercept equation that represents this linear function is f(x)=-2x+5.

A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely. The equation of the given line is y=-2x+5.

A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely. The equation of a line is given by,

y =mx + c

where,

x is the coordinate of the x-axis,

y is the coordinate of the y-axis,

m is the slope of the line, and

c is the y-intercept.

The given line passes through two points with coordinates (0,5) and (1,3). Therefore, the slope and the y-intercept of the given equation of a line can be written as,

Slope, m = (5 - 3)/(0 - 1) = 2/-1 = -2

y-intercept, c = 5

Now, the equation of the line can be written as,

y = mx + c

y = -2x + 5

Hence, the equation of the given line is y=-2x+5.

Answer:

Parallel lines have same slope but different y-intercept

None of the given equations have same slope. Therefore lines are not parallel.

Step-by-step explanation:

Slope of Line a: 4y +x=8 is -1/4

Slope of Line b: 2y + x = 4 is -1/2

Slope of Line c: 2y = -3x + 6 is -3/2

Since the slope of the parallel lines is equal and the slope of the given lines is not equal the lines are not parallel.

The ratio that y increase as x increases is the slope of a line. The slope of a line reflects how steep it is, but how much y increases as x increases. Anywhere on the line, the slope stays unchanged (the same).

[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]

It is given that, the lines are.

Line a: 4y +x=8

Line b: 2y + x = 4

Line c: 2y = -3x + 6

Line a,

4y +x=8

4y= -x+8

y=-1/4x+2

Compare the given equation with the standard equation, y=mx+c in order to find the value of slope(m).

The slope of line a is -1/4.

Line b:

2y + x = 4

2y=-x+4

y=  -1/2x+2

The slope of line b is -1/2.

Line c:

2y = -3x + 6

y= -3/2x+3

The slope of line c is -3/2

The slopes of the line  4y +x=8, 2y + x = 4 and 2y = -3x + 6 will be -1/4, -1/2 and  -3/2 respectively.

Thus, if the slope of the parallel lines is equal and the slope of the given lines is not equal the lines are not parallel.

To find the answer of this equation, you would use the law of sine

so... (18)/sin(90)= (x)/sin(45)

to find for the length of one side simply isolate for x.

Because sin(90) equals 1, you just have to multiply 18 by sin(45) which equals [tex]\sqrt{2}[/tex]/2

Answer:

2 hours 15 minutes

Step-by-step explanation:

Given that :

Ben's speed = 3 mi/hr

One and half hours after Ben leaves = 1.5 hours

Ben's distance = 3 mi/hr * 1.5 = 4.5 miles

Amanda's speed = 5 mi/hr

Time taken before Amanda catches up:

Let time taken = x

Distance = speed * time

Ben's distance = Amanda's distance

4.5 mi + (3 * x) = 5 * x

4.5 + 3x = 5x

4.5 = 5x - 3x

4.5 = 2x

x = 4.5 / 2

x = 2.25 hours

Time taken = 2.25 * 60 = 135 minutes = 2 hours 15 minutes

It would take Amanda 2.25 hours to catch up with Ben

Speed is the ratio of distance to time. It is given by:

Speed = distance/time

Given that Ben covers a distance d at time t, hence:

3 = d/t

d = 3t

Since Amanda leaves One and a half hours (1.5) after Ben leaves, hence Time = t - 1.5

5 = d/(t - 1.5)

d = 5t - 7.5

Since they catch up, hence:

3t = 5t - 7.5

2t = 7.5

t = 3.75 hours

Time for Amanda = t - 1.5 = 3.75 - 1.5 = 2.25 hours

Hence it would take Amanda 2.25 hours to catch up with Ben.

Pythagorean theorem

in the right angle triangles there is a relationship that governs the length of the three sides. if we knows the length of any two sides, the third side may be calculated by the use of the Pythagorean theorem.

This theorem states that the square on the hypotenuse of a right angled triangle is equal to the sum of the squares on the remaining two sides.

Answer:

Step-by-step explanation:

25π*12=300π

The approximate volume of the given cylinder is 942.48 ft³.

The volume of the cylinder is the density which signifies the amount of substance it can hold.

Mathematically,

                        V = πr²h

where, r is the radius of the cylinder

and h is the height of the cylinder.

It is given that,

Height h of the cylinder = 12 ft

Diameter d of the cylinder = 10 ft

⇒ Radius r = d/2

⇒ r = 10/2

⇒ r = 5 ft

Now, Volume of the cylinder V = πr²h

Putting the values of r and h of given cylinder. We get,

⇒ V = 3.14 × (5 ft)² × 12ft

⇒ V = 3.14 × 25 ft² × 12 ft

⇒ V = 3.14 × 300 ft³

⇒ V ≈ 942.48 ft³

The approximate volume of the given cylinder is 942.48 ft³.

Answer:

Trapezoid A'B'C'D' is smaller than trapezoid ABCD because the scale factor is less than 1.

Step-by-step explanation:

Trapezoid A'B'C'D' is smaller than trapezoid ABCD because the scale factor is less than 1.

We have given that,Trapezoid ABCD is shown on the coordinate grid. Trapezoid ABCD is dilated with the origin as the center of dilation using the rule (x, y)→(0.4x, 0.4y) to create trapezoid A'B'C'D'.

We have to find the correct statement.

If the scale factor is greater than 1, the image is an enlargement (a stretch). If the scale factor is between 0 and 1, the image is a reduction (a shrink). If the scale factor is 1, the figure and the image are congruent.

Therefore from the given we can conclude that the statement,

If the scale factor is between 0 and 1, the image is a reduction

Therefore,Trapezoid A'B'C'D' is smaller than trapezoid ABCD because the scale factor is less than 1 is correct.
