Which of the following is equivalent to -17/9

Answer:

measure of each base angle =  80 each angle

measure of vertex angle = 20

Step-by-step explanation:

x=base angle    

2x+ x/4= 180

Multiply everything by 4 to eliminate the fraction

8x+x = 720

9x=720

x=80

80/4=12

Final answer:

In an isosceles triangle where the vertex angle is one-fourth the measure of a base angle, using the properties of a triangle and the Triangle Angle Sum Theorem, we find each base angle measures 80 degrees and the vertex angle measures 20 degrees.

Explanation:

Given an isosceles triangle, where the vertex angle is one-fourth the measure of a base angle, we can find the measures of the angles using the properties of a triangle. From the Triangle Angle Sum Theorem, we know that the sum of the angles in any triangle is 180 degrees.

Let's denote the measure of the base angle as 'b'. Since the triangle is isosceles, both base angles are equal, so we have 2b for the sum of the base angles. The vertex angle, being one-fourth of a single base angle, is ¼×b = b/4. According to the Triangle Angle Sum Theorem, we can write:

2b + (b/4) = 180

Multiplying through by 4 to clear the fraction gives us:

8b + b = 720

Combining like terms:

9b = 720

Dividing both sides by 9 gives us:

b = 80

Now that we have the measure of the base angle, we can find the measure of the vertex angle:

measure of vertex angle = b/4

Substitute b = 80 into the equation:

measure of vertex angle = 80/4

measure of vertex angle = 20

So, the measure of each base angle is 80 degrees, and the measure of the vertex angle is 20 degrees.

Answer:

576

Step-by-step explanation:

8*8 = 64

If dimensions are tripled, you get 24. 24*24 = 576

576

Step-by-step explanation:

A=L*W

8*8=64

8*3=24

24*24=576

The equation of line parallel to y = -5x + 6 and passes through the point (-4, -1) is y = -5x -21

Given that, a line passes through (-4, -1) and it is parallel to y = -5x + 6

We have to find the line equation of that line.

Now, as we can see given line equation is in slope intercept form y = mx + c

where "m" is the slope of line and "c" is the y-intercept

So, by comparison, slope of that line is m = -5

We know that slopes of two parallel lines are equal

And as the required line is parallel to given line, it will also have the same slope.

Then, slope of our line = -5

And let us find the line equation point slope form

y – a = m(x - b) where (b, a) is a point on the line

So, line equation is y – (-1) = -5(x – (-4))

y + 1 = -5(x + 4)  

y + 1 = -5x – 20  

y = -5x -20 – 1

y = -5x -21

Thus the equation of required line is y = -5x -21  

The equation of the line parallel to y = -5x + 6 and passing through (-4, -1) is y = -5x - 21, which is determined using the point-slope form of a line with the given point and the parallel line's slope.

To find an equation of a line that is parallel to the given line y = -5x + 6 and passes through a specific point (-4, -1), we need to use the point-slope form of the equation of a line, which is y - y1 = m(x - x1), where m is the slope and (x1, y1) is a point on the line.

Since parallel lines have the same slope, the line we are looking for will also have a slope of -5. Using the point (-4, -1) and the slope -5, we can substitute these values into the point-slope form:

y - (-1) = -5(x - (-4))
y + 1 = -5(x + 4)
y = -5x - 20 - 1
y = -5x - 21

Thus, the equation of the line is y = -5x - 21.

This is only if you are looking to find the Arch AED        11pi/4

Step-by-step explanation:

See photo

Arc length AED of a given circle with a radius of 3 units is 11π/4.

According to the given diagram,

The angle subtended by arc AED or central angle = 360°-120°-45°-30° = 165°

The radius of the circle = 3 units

Arc length = Central angle(in radians) * Radius

So, arc length AED = 165 *π/180 * 3

Arc length AED = 11π/12 * 3 = 11π/4

Therefore, the Arc length AED of a given circle with a radius of 3 units is 11π/4.

Answer:

The combined cost of 1 pound of salmon and 1 pound of swordfish is $16.66

Step-by-step explanation:

Let us assume the cost of 1 pound salmon = $ m

So the cost of 1 pound of 1 pound swordfish cat = $ ( m - 0.20)

Now, the Amount of salmon purchased  = 2 1/2 pounds

[tex]2\frac{1}{2}  = 2 + \frac{1}{2} = 2 + 0.5 = 2.5[/tex]

So, the amount of salmon purchased = 2.5 pounds

Cost of buying 2.5 pounds = 2.5 x ( 1 pound cost)

= 2.5 ( m) = $ 2.5 m  ...... (1)

Also, the Amount of swordfish purchased  = 1 1/4 pounds

[tex]1\frac{1}{4}  = 1 + \frac{1}{4} = 1 + 0.25 = 1.25[/tex]

So, the amount of swordfish purchased = 1.25 pounds

Cost of buying 1.25 pounds = 1.25 x ( 1 pound cost of swordfish)

= 1.25 ( m - 0.20) = $ 1.25 m - 0.25       .... (2)

Now, the combined cost paid  = $ 31.25

⇒Cost of buying (2.5 pounds salmon  +  1.25 pounds swordfish) = $ 31.25

or, 2.5 m +   1.25 m - 0.25  = 31.35       (from (1) and (2))

or, 3.75 m = 31.60

or, m = 31.60/3.75 =  8.43

⇒ m = $8.43

So, the cost of 1 pound salmon = m = $8.43

and the cost of 1 pound swordfish = m - 0.20 = $8.43 - 0.20 = $ 8.23

Hence, the combined cost  1 pound of salmon and 1 pound of swordfish = $8.43 + $ 8.23 =  $ 16.66

Answer:

x

Step-by-step explanation:

Pull terms out from under the radical, assuming positive real numbers.

Answer:

x

Step-by-step explanation:

If the measure of the supplement of an angle is 60 degrees less than four times the measure of the complement of the angle, the required angle will be 40degrees.

Let the measure of the required angle be x

Supplement of the angle = 180 - x ....................1

Complement of the angle = 90 - x

four times the measure of the complement of the angle = 4(90-x)

60 degrees less than four times the measure of the complement of the angle = 4(90-x) - 60 ................................ 2

Equate 1 and 2 to get the unknown value 'x'

180 - x = 4(90-x) - 60

180 - x = 360-4x-60

180 - x = 300 - 4x

Collect the like terms

-x + 4x = 300 - 180

3x = 120

Divide both sides by 3

3x/3 = 120/3

x = 40

Hence the measure of the required angle is 40 degrees

The measure of the angle is found to be 40 degrees. This was determined by setting up and solving the equation based on the given relationships between the angle's supplement and complement. Therefore, the angle measures 40 degrees.

To find the measure of the angle, let's denote the angle as x. We know the following:

According to the problem, the supplement of the angle is 60 degrees less than four times the complement of the angle. Therefore, we have the equation:

(180 - x) = 4(90 - x) - 60

First, expand and simplify the right-hand side:

180 - x = 360 - 4x - 60

Combining like terms, we get:

180 - x = 300 - 4x

Next, add 4x to both sides to start isolating x:

180 + 3x = 300

Then, subtract 180 from both sides:

3x = 120

Finally, divide both sides by 3:

x = 40

Thus, the measure of the angle is 40 degrees.

Step-by-step explanation:

The graph is attached below.

We have to find the [tex]x[/tex] intercept meaning the value of the point on[tex]x-axis[/tex] when [tex]y=0[/tex]

So we will put the value of zero [tex](0)[/tex] instead of [tex]y[/tex] in our given equation.

So here we have solved it algebraically.

[tex]y=\frac{3}{4}x-3[/tex]

Putting [tex]y=0[/tex]

[tex]0=\frac{3}{4}x-3[/tex]

[tex]0=\frac{3x-12}{4}[/tex]

Multiplying [tex]4[/tex] both sides.

[tex]0=3x-12[/tex]

Adding [tex]12[/tex]both sides.

[tex]12=3x[/tex]

Dividing with [tex]3[/tex] both sides.

[tex]x=\frac{12}{3}=4[/tex]

Step-by-step explanation:

Given:

[tex]\overline{AB}\cong \overline{AC},[/tex]

[tex]\overline{AD}[/tex] bisects angle BAC

[tex]m\angle C=54^{\circ}[/tex]

Triangle ABC is isosceles triangle, because [tex]\overline{AB}\cong \overline{AC}.[/tex] Angles adjacent to the base of isosceles triangle ABC are congruent.

Hence,

[tex]m\angle C=m\angle B=54^{\circ}[/tex]

The sum of the measures of all interior angles is 180°, so,

[tex]m\angle B+m\angle C+m\angle BAC=180^{\circ}\\ \\m\angle BAC=180^{\circ}-2\cdot 54^{\circ}=72^{\circ}[/tex]

Since [tex]\overline{AD}[/tex] bisects angle BAC, angles BAD and CAD are congruent by definition of angle bisector. So,

[tex]m\angle BAD=m\angle CAD=\dfrac{1}{2}m\angle BAC=\dfrac{1}{2}\cdot 72^{\circ}=36^{\circ}[/tex]

AD ia angle bisector in isosceles triangle drawn to the base, so it is the height. Thus, AD and BC are perpendicular. So,

Answer:

P(E or F) = 0.75

Step-by-step explanation:

Given;

P(E)=0.30

P(F)=0.45

We need to find probability of P(E or F).

Now by General theorem of probability addition theorem:

P(E or F) = P(E) + P(F) - P(E and F)

For mutually exclusive events, P(E and F) = 0

So, P(E or F) = P(E) + P(F) = [tex]0.3 +0.45 = 0.75[/tex]

Hence P(E or F) = 0.75

Probabilities are used to determine the chances of an event.

The probability of P(E or F) is 0.75

The parameters are given as:

[tex]\mathbf{P(E) = 0.30}[/tex]

[tex]\mathbf{P(F) = 0.45}[/tex]

[tex]\mathbf{P(E\ or\ F) = P(E) + P(F)}[/tex]

So, the equation becomes

[tex]\mathbf{P(E\ or\ F) = 0.30 + 0.45}[/tex]

[tex]\mathbf{P(E\ or\ F) = 0.75}[/tex]

Hence,  the probability of P(E or F) is 0.75

The minimum possible area of the rectangle is 19.25 m² and the maximum possible area is 29.25 m².

To find the minimum and maximum possible areas of the rectangle, we need to consider the possible values that the length and width can take.

Given that the measured dimensions are 6 m by 4 m to the nearest whole unit, the minimum possible length would be 5.5 m (6 m - 0.5 m) and the minimum possible width would be 3.5 m (4 m - 0.5 m).

Similarly, the maximum possible length would be 6.5 m (6 m + 0.5 m) and the maximum possible width would be 4.5 m (4 m + 0.5 m).

To calculate the minimum and maximum possible areas, we multiply the minimum and maximum possible lengths by the minimum and maximum possible widths respectively. The minimum possible area would be 5.5 m x 3.5 m = 19.25 m² and the maximum possible area would be 6.5 m x 4.5 m = 29.25 m².

The equation of a circle if the ends of the diameter are (18,-13) and (4,-3)​ is [tex](x-11)^{2}+(y+8)^{2}=74[/tex]

Given that ends of diameter are (18, -13) and (4, -3)

To find the equation of circle, let us first find the center (h, k) of the circle

We know that the center of the circle lies in the center of the diameter also. In order to find the center, get the average of both x and y

[tex]\mathrm{c}=\left(\frac{x_{1}+x_{2}}{2}, \frac{y_{1}+y_{2}}{2}\right)[/tex]

[tex]\begin{array}{l}{c=\frac{18+4}{2}, \frac{-13-3}{2}} \\\\ {c=\frac{22}{2}, \frac{-16}{2}} \\\\ {\mathrm{c}=(11,-8)}\end{array}[/tex]

These are the coordinates of the center of the circle

Now we need to find the radius, we need the center (h, k) and one of the given points (4, -3):

The equation of circle is given as:

[tex](x-h)^{2}+(y-k)^{2}=r^{2}[/tex]

[tex]\begin{array}{l}{(4-11)^{2}+(-3-(-8))^{2}=r^{2}} \\\\ {(-7)^{2}+(-3+8)^{2}=r^{2}} \\\\ {(-7)^{2}+(5)^{2}=r^{2}} \\\\ {49+25=r^{2}} \\\\ {r=\sqrt{74}}\end{array}[/tex]

So the equation of the circle is:
