Number: 365
Exponent: 100

365 days in a year, and 100 days of rainfall. So 365 X itself 100 times.

Tamara was asked to write an example of a linear functional relationship. She wrote this example: My babysitting service charges

Vlada [557]

Answer:

Hours Charge

1 y = 6.5(1) + 5 = $11.5

2 y = 6.5(2) + 5 = $18

3 y = 6.5(3) + 5 = $24.5

4 y = 6.5(4) + 5 = $31

Step-by-step explanation:

In an equation y=mx+b, we can interpret the intercept b as the value of the initial charge and the slope m as the additional charge per hour. So, we can formulate the following equation:

y = 6.5x + 5

Where x is the hours and y are the charges for the babysitting, so, we can fill the table as:

Hours Charge

1 y = 6.5(1) + 5 = $11.5

2 y = 6.5(2) + 5 = $18

3 y = 6.5(3) + 5 = $24.5

4 y = 6.5(4) + 5 = $31

If abx-5=0 what is x in terms of a and b

Nady [450]

$abx - 5 = 0$

Add 5 to both sides:
$abx = 5$

Divide by <em>ab</em>:
$x = \frac{5}{ab}$

Tom went on a bike to the store 3 miles away. If it took Tom 1/2 of an hour to get there and 2/3 of an hour to get back , what w

anastassius [24]

Answer:

5.14 mi/h

Step-by-step explanation:

To find the average speed, we simply find the total distance traveled by Tom and divide that by the total time the entire journey took him.

Average speed = (total distance traveled) / (total time taken)

TOTAL DISTANCE TRAVELED

He traveled 3 miles to and 3 miles fro. Hence:

3 + 3 = 6 miles

TOTAL TIME TAKEN

He spent ½ hr to go and ⅔ hr to return back. Hence:

½ + ⅔ = 7/6 hr

Therefore, the average speed is:

v = 6 / (7/6)

v = 36 / 7 = 5.14 mi/h

Tom's average speed was 5.14 mi/h.

Describe in words the surface whose equation is given. (assume that r is not negative.) θ = π/4

Delvig [45]

An equation in the form $\theta=\dfrac{\pi}{4}$ is the line
that goes through the origins and whose tangent equates $\dfrac{\pi}{4}$ . In general, any equation in the form $\theta=\theta_0$
is the equation of a line.

Find the area of irregular figure

elixir [45]

Step-by-step explanation:

For square

A=bh

A=30(20)

A=60in²

For triangle

A=½bh

A=½(40)(30)

A=½(120)

A=60in²

Add

60+60=120in²
