Find the perimeter of the semicircular region

→ You will pay $ 89.7.

The tip value is based on the bill value. Hence, to find the total payment you have to multiply 78 by 1.15 (this includes the tip, 1.15).

The constant speed for the given distance and time is 123/2 miles/hour.

Given that, Andrea drove [tex]20\frac{1}{2}[/tex] miles in 1/3 of an hour at constant speed.

The speed formula can be defined as the rate at which an object covers some distance. Speed can be measured as the distance travelled by a body in a given period of time. The SI unit of speed is m/s.

Here, [tex]20\frac{1}{2} = \frac{41}{2}[/tex]

Now, speed = Distance ÷ Time

= 41/2 ÷ 1/3

Change division to multiplication and reciprocal the fraction

That is, 41/2 × 3/1

= 123/2 miles/hour

Therefore, the constant speed for the given distance and time is 123/2 miles/hour.

Answer:

5 houses

Step-by-step explanation:

She needs to visit 5 houses as 20 divided by 4 is 5

Answer:

2 is the correct answer

The three equivalent ratios are 6/1 gallons/minute, 1/40 quarts/second and 360/1 gallons/hour.

The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.

Given that, Tiffany can fill the pool at a rate of 1/10 gallons per second.

Equivalent ratios are the ratios that are the same when we compare them.

We know that, 60 seconds =1 minute

1/10 × 60 = 6 gallons/minute

1 gallon = 4 quarts

1/10 = 1/10×4 = 1/40 quarts/second

1 hour =60 minute

So, 6 gallons/minute =6×60

= 360 gallons/hour

Here, 6 gallons/minute = 1/40 quarts/second = 360 gallons/hour

Therefore, the three equivalent ratios are 6/1 gallons/minute, 1/40 quarts/second and 360/1 gallons/hour.

Angle 8 and angle 5 are vertical angles

Step-by-step explanation:

4a)

the principle of similar triangles : they have the same angles.

and we do not forget : the sum of all angles in a triangle is always 180 degrees.

a = 180 - 65 - 45 = 70 degrees

b = 65 degrees

c = 70 degrees

b)

same principles.

x = 58 degrees

y = 52 degrees

z = 180 - 58 - 52 = 70 degrees

c)

same principles.

plus the fact that complementary angles around a point on one side of a line are also together 180 degrees.

x = 85 degrees

y = 180 - 40 - 85 = 55 degrees

z = 180 - 85 = 95 degrees

d)

again same principles.

y = 2x (as these 2 angles correspond to each other among the 2 similar triangles).

the angle POQ is again complementary with 87 degrees,

POQ = 180 - 87 = 93 degrees

x + y + 93 = x + 2x + 93 = 180

3x = 87

x = 29 degrees

y = 2x = 2×29 = 58 degrees

The value of the function if the independent variable is equal to -1 is -2

Given the function p(x) = x^3 - 1

The input variable "x" is the independent variable. If the independent variable is equal to -1, the value of the function will be expressed as:

P(-1) = (-1)^3 - 1

P(-2) = -1 -1

P(-2) = -2

Hence the value of the function if the independent variable is equal to -1 is -2

Answer:

y = -4/3x -9

Step-by-step explanation:

Slope intercept form is

y = mx+b where m is the slope and b is the y intercept

8x+6y = -54

Subtract 8x from each side

8x+6y-8x = -8x-54

6y = -8x-54

Divide each side by 6

6y/6 = -8x/6 -54/6

y = -4/3x -9

Answer:

y = -4/3x - 9

Step-by-step explanation:

Putting this into 'y=mx+c' form:

i) Firstly, make it only y on the LHS:

6y = -8x-54

ii) Secondly, making the 'y' have a co-efficient of 1. This can be done by dividing both sides by 6:

6y/6 = -8x/6 - 54/6

y = -4/3x - 9

Hence,

y = -4/3x - 9

Answer:

we need more information to solve your problem.

Step-by-step explanation:

Answer:

y = 150º

Step-by-step explanation:

The sum of internal angles of a triangle must be 180º and the sum of y + (x-20) forms a straight line which is also 180º, so:

2x + x + (x - 20) = 180

4x - 20 = 180

4x = 200

x = 50

x - 20 = 50 - 20

x - 20 = 30

y = 180 - 30

y = 150º
