Answer:

$30.60

Step-by-step explanation:

What we know:

The bill for Mr. Wilson's diner meal is $25.50.

He gives a 20% tip to the waiter.

To figure out this tip, multiply 1/5 by 25.5.

1/5 * 51/2

51/10 = $5.10 tip.

Here, it's asking for the total, including the $5.10 tip. So, add $5.10 to $25.50 for $30.60 total, including the tip.

(For a simpler method *multiply 6/5 by $25.5)

Answer:

In Explanation.

Step-by-step explanation:

In situations like this, you want to first find the equations of the individual lines.

Let's start with the left one.

It has a negative slope of 2 while it has a y-intercept of 1

y=-2x+1

is the equation.

The other line has a slope of 3/2.

The y-intercept is not visible, so we need to use point slope form.

I chose (2,-3)

y+3=3/2(x-2)

Simplify.

y=3x/2-3-3

y=3x/2-6

so we have

y=-2x+1

and

y=[tex]\frac{3x}{2}[/tex]-6

Since both lines are solid, the signs are ≥ or ≤

The shadings intersect above both lines so the individual shadings also have to be above the line.

That means the equation is less than the "y".

y≥-2x+1

y≥[tex]\frac{3x}{2}[/tex]-6

Answer:

30541

Step-by-step explanation:

8⁰ = 1

8¹ = 8

8² = 64

8³ = 512

8⁴ = 4096

8⁵ = 32768 > 6467

We have

6467 ÷ 8⁴ = 1 (mod 2371)

2371 ÷ 8³ = 4 (mod 323)

323 ÷ 8² = 5 (mod 3)

3 ÷ 8 = 0 (mod 3)

3 ÷ 1 = 3

=> 6467 in the base-eight system: 30541

Answer:

B. y > -2x + 4

Step-by-step explanation:

we know it's y greater than (>) because the shaded region is above the line. Its a dashed line because it's >. If it was ≤ or ≥ symbol it would be a bolded straight line not dashed.

We can tell from the graph that the y-intercept is (0,4). the slope is -2

Step-by-step explanation:

The lengths of the legs of the right triangle from the coordinates will be 2.24 units.

Let one point be (x, y) and another point be (h, k).

Then the distance between the points will be

D² = (x - h)² + (y - k)²

Vega uses a coordinate system using yards as the units to create a map of a park that is situated on her street. A park seat is located at position (-1, 1) and the park gate is located at (1, 2).

Then the lengths of the legs of the right triangle from the coordinates will be

D² = (1 + 1)² + (2 - 1)²

D² = 2² + 1²

D² = 4 + 1

D² = 5

D = √5

D = 2.24 units

The lengths of the legs of the right triangle from the coordinates will be 2.24 units.

Answer:

x=4 or -4

Step-by-step explanation:

4 squared is 16, and 4 times 16 is 64

The solution is, the solutions to the quadratic equation 4x^2= 64 are, Ox= -4 and X = 4.

A square root of a number is a value that, when multiplied by itself, gives the number. In mathematics, a square root of a number x is a number y such that y² = x; in other words, a number y whose square is x.

For example, 4 and −4 are square roots of 16, because 4² = ² = 16.

here, we have,

given that,

the quadratic equation 4x^2= 64

now, we have to simplify the equation,

at first, take 4 common from both sides,

we get,

x^2= 16

now, taking square root on both side, we get,

x = ±4

Hence, The solution is, the solutions to the quadratic equation 4x^2= 64 are, Ox= -4 and X = 4.

Answer:

4 hours ; 200 kmph

Step-by-step explanation:

Given that :

Distance to be covered = 300 km

Speed of travel = 75kmph

Number of hours it will take to get to destination :

Time taken = Distance / speed

Time taken = 300 km / 75 kmph

Time taken = 4 hours

2.) If he has 90 minutes to get to destination, required speed will be ; 90 minutes = 1.5 hours

Speed = distance / time

Speed = 300 km / 1.5 hours

Speed = 200 kmph

Answer: 17.5 or 35/2

Step-by-step explanation:

(If you change 4/5 to a decimal, it makes this easier. 4/5 would be 0.8.)

23.6 = (12 + x)*0.8

23.6 = 9.6 + 0.8x

14 = 0.8x

17.5 = x

17.5 as an improper fraction would be 35/2.

Step-by-step explanation:

To find the height of a right angular cone, the formula is: [tex]\sqrt{l^{2} - r^{2}}[/tex]

Height = [tex]\sqrt{15^{2} - 12^{2}}[/tex]

           = [tex]\sqrt{225 - 144}[/tex]

           = [tex]\sqrt{81}[/tex]

           = 9

the radius of a cone is 15,the slant height is 12

calculate the height

h = √(s2 - r2)

H=√[12^2-15^2]

H=√ (144-225)

H=√-81

the square root of -81 is not considered as a number

hence,

the - is removed

= √81

Answer:

Step-by-step explanation:

use Pythagorean theorem:

a² + b² = c²

where a = 4/2 = 2

           b = 5

           c = x

plugin values into the formula:

2² + 5² = x²

x = √(2² + 5²)

x = √29

The length of the side x of the isosceles triangle is x = √29 units

A triangle is a plane figure or polygon with three sides and three angles.

A Triangle has three vertices and the sum of the interior angles add up to 180°

Let the Triangle be ΔABC , such that

∠A + ∠B + ∠C = 180°

The area of the triangle = ( 1/2 ) x Length x Base

For a right angle triangle

From the Pythagoras Theorem , The hypotenuse² = base² + height²

if a² + b² = c² , it is a right triangle

if a² + b² < c² , it is an obtuse triangle

if a² + b² > c² , it is an acute triangle

Given data ,

Let the triangle be represented as ΔABC

The measure of side AB = AC = x

The measure of BC = 4 units

Now , let AD be the perpendicular bisector of the triangle and AD = 5 units

where the measure of BD = measure of CD

And , right angle triangle

From the Pythagoras Theorem , The hypotenuse² = base² + height²

So , the measure of x = √ ( AD )² + ( BD )²

x = √ ( 25 ) + ( 4 )

x = √29 units

Hence , the length of side of triangle is x = √29 units
