34+41=75m
D^2=34^2+41^2
D^2=1156+1681
D^2=2837
D=sqrt(2837)
75-(sqrt(2837)
=21.7365

To find the straight line distance from A to B, use the Pythagorean Theorem:  AC2 + CB2 = AB2   --->   412 + 342  =  ab2

--->   2837 =  AB2   --->   AB =  53.3

Walking from A to C to B =  41 + 34 = 75 meters.

Walking from A to B will save you 75 - 53.3 = 21.7 meters.

A dog walker charges a flat rate of $6 per walk plus an hourly rate of $30. How much does the dog walker charge for a 45 minute
zvonat [6]

Step 1

<u>Find the equation in function notation</u>

Let

h-------> the number of hours

y-------> the function for the walker fee in dollars

we know that

the hourly rate is 30\frac{\$}{hour}

y=6+30h

in this linear equation

the independent variable is the variable h

the dependent variable is the variable y

<u>Convert to function notation</u>

Let

f(h)=y

f(h)=6+30h

Step 2

Find how much does the dog walker charge for a 45 minute walk

Convert the time in hours

1\ hour=60\ minutes

45\ minutes=45/60=0.75\ hours

substitute in the equation

For h=0.75\ hours

f(0.75)=6+30*(0.75)=\$28.5

therefore

<u>the answer is</u>

the dog walker charge for a 45 minute walk \$28.5

<u>Statements</u>

Step 3

<u>The dependent variable is the number of hours true or false</u>

The statement is false,

because the independent variable is the number of hours and the dependent variable is the walker fee in dollars

Step 4

<u>The function for the walker fee is f(h)= 30h+6 true or false</u>

The statement is True --------> see the Step 1

Step 5

<u>The dog walker charges $22.5 for a 45 min walk true or false</u>

The statement is False

Because the dog walker charges for a 45 minute walk \$28.5

A certain fraction is greater than 2. The denominator is 8. What must be true about the numerator?
Volgvan

Answer:

The numerator must be greater than 16

Step-by-step explanation:

We are told that a certain fraction is greater than 2. Thus, if the numerator and denominator are x and y respectively, then we have;

x/y > 2

We are further told that the denominator is 8.

Thus;

x/8 > 2

Multiply both sides by 8 to give;

x > 16

Thus,the numerator must be greater than 16.

An airplane travel at a constant speed of 575 miles per hour.write and equation that can be used to determine the number of mile
Oxana [17]

Answer:

m = 575h

Step-by-step explanation:

Given

Rate = 575 miles/hour

Required

Determine the equation for the model

Represent the number of hours with h and the miles with m.

Using distance formula:

Distance = Speed * Time

In this case, it is:

Miles = Rate * Hour

So, we have:

m = 575 * h

m = 575h
