Answer: Corresponding angles postulate

Answer:

The piecewise equation is given as :[tex]A(t)=\begin{cases} 25x& \text{ if } 0 \leq x \leq 3 \\ 75& \text{ if } 3<x<4 \\ 75+20(x-4) & \text{ if } 4 \leq x \leq 6\end{cases}[/tex]

Step-by-step explanation:

Let x be the time in hour and A(x) be the amount of accumulating rainfall at time x.

We are given that in the first three hours the rain fell at a constant rate of 25mm per  hour

Amount of rainfall in 1 hour = 25

Amount of rainfall in t hours = 25x

[tex]A(x) = 25x ; 0 \leq x \leq 3[/tex]

The rain then slows down and remains constant

So, Amount of rain for that hour = [tex]25 \times 3 = 75 mm[/tex]

75 mm ; 3

Now we are given that started again at a constant rate of 20 mm  per hour for the next two hours.

Amount of rain after 4 hours = [tex]75+20(x-4) ; 4 \leq x\leq 6[/tex]

The rain increases at a rate of 20t from 4 ≤ x ≤ 6.

Hence the piecewise equation is given as :[tex]A(t)=\begin{cases} 25x& \text{ if } 0 \leq x \leq 3 \\ 75& \text{ if } 3<x<4 \\ 75+20(x-4) & \text{ if } 4 \leq x \leq 6\end{cases}[/tex]

Step-by-step explanation:

length = x

width = 2x-8

b.) to get the area you need to multiply the length and the width.

l×w= area

x(2x-8)

2x^2-8x

c.) 2x^2-8x = 10

subtract 10 both sides

2x^2-8x-10 = 0

2(x^2-4x-5) = 0

2(x-5)(x+1) = 0

x = 5

the area would be 10.

Solving steps:

Question: Sam had some money in his pocket, and he found another $6. 50 in his dresser drawer. He then had a total of $19. 75. Let p represent the amount of money Sam had in his pocket. Which equation can you use to find the amount of money Sam had in his pocket? How much money did Sam have in his pocket?.

Find: How much money did Sam have in his pocket?.

Solution: Let the equation be

p represent amount of money

p represent amount of moneyt represent total

p represent amount of moneyt represent totalf represent money found

insert the values

add 19.75 from 6.50

THEREFORE THE AMOUNT OF MONEY SAM HAVE IN HIS POCKET IS ABOUT $26.25

Answer:

p + 6.5 = 19.75

2 cm

scale factor of 3

then 6/3 = 2 cm

Answer:

C.  2 cm

Step-by-step explanation:

As the circumference is a measure of length (one dimension), we can simply divide the given circumference of circle N by the scale factor to find the circumference of circle M:

⇒ circumference of circle M = circumference of circle N ÷ scale factor

                                                = 6 cm ÷ 3

                                                = 2 cm

(If we were working with area, we would have to divide/multiply by the square of the scale factor, since we would be working in 2 dimensions)

Answer:

72.22

Step-by-step explanation:

C = [tex]\pi \: d[/tex]

3.14×23=72.22

The circumference of a circle whose radius is 11.5 inches.

Thus, option (a) is correct.

Given:

Diameter = 23 inch

So, Radius of circle = diameter/2

                                =23/2

                                = 11.5 inch

Now, the formula for circumference of a circle is

= 2πr

Substituting the value of r= 11.5 into the formula as

= 2 x 3.14 x 11.5

= 72.22 inches

Thus, the circumference of circle is 72.22 inches.

Answer:

1107.0213 cm

Step-by-step explanation:

Assuming this gutter is half a cylinder,

Volume of half a cylinder = 0.5(πr²l)²

where, Volume = 20l, π = 3.142, r = 0.5(11.5) and l = ?

But, the other units are in cm while the Volume is in liters, so let's convert the liters to cm³

It would be easier to convert the liters to m³ then to cm³ rather than converting directly. So,

1000 L = 1 m³

     1 L = ?

1 ÷ 1000 = 0.001 m³

      1 m³ = 1,000,000cm³

0.001 m³ = ?

0.001 x 1,000,000 = 1000 cm³

So, if 1 L = 1000 cm³

      20 L = ?

20 x 1000 = 20,000 cm³

Thus, 20,000 = 0.5(3.142 x 0.5(11.5) x l)

20,000 = 0.5(3.142 x 5.75 x l)

20,000 = 18.0665l

Make l the subject and divide both sides by 18.0665

length = 1107.0213 cm

2) 50

Step-by-step explanation:

1)

To find the perimeter, add the lengths of the sides.

perimeter = 3s - 1 + 2s + 5 + s + 4

perimeter = 6s + 8

2)

Replace s with 7 in the perimeter expression.

perimeter = 6(7) + 8

Given that,

A G.P. Bulk bills at $41.20 per consultation, and sees a new patient every 15 minutes for 3 hours.

Solution,

3 hours means 180 minutes

It means that he sees a new patient every 15 minutes for 180 minutes.

No of patients = [tex]\dfrac{180}{15}=12[/tex]

Fees for per consultation is $41.20. Total bill will be :

Bill = $41.20×12

= $494.4

He has not converted 3 hours to minutes. It is the error made by the new employee. He get wrong Medicare bill for the patients.
