Answer:

3.33 hours

Step-by-step explanation:

Take the total bill minus the flat charge. ($300 - $50 = $250)

Then take that amount and divide by the charge per hour.

($250/$75) = 3.33 hours

total money ÷ times money was taken out= how much has been taken out.

Hewwo!
ella [17]

Answer:

See Below.

Step-by-step explanation:

Please refer to the diagram below.

We are given that O is the center of the circle, and chords MN and RS are intersected a P. OP is the bisector of ∠MPR. And we want to prove that MN = RS.

We will construct segments OK and OJ such that it perpendicularly bisects MN and RS.

Since OP bisects ∠MPR, it follows that:

\displaystyle \angle JPO\cong \angle KPO

And since OK and OJ are perpendicular bisectors:

m\angle OKP=90^\circ \text{ and } m\angle OJP=90^\circ

Therefore:

\angle OKP\cong \angle OJP

By the Reflexive Property:

OP\cong OP

Therefore:

\Delta OKP\cong \Delta OJP

By AAS Congruence.

Hence:

OK\cong OJ

By CPCTC.

Recall that congruent chords are equidistant from the center.

Thus, by converse, chords that are equidistant from the center are congruent.

Therefore:

MN\cong RS

The cost of a service call to fix a washing machine can be expressed by the linear function y = 45 x + 35, where y represents th
Effectus [21]

Answer:

B. The service fee for coming to look at the machine

Step-by-step explanation:

Whenever we have a linear equation like this in real-world problems, the y-intercept always represents a fixed cost of some sort.

Here, 35 is the y-intercept. It cannot represent "the cost for each hour it takes to repair the machine" because that's what 45 means.

It cannot represent "the total cost for fixing the washing machine" because that's what y means.

And it cannot represent "the amount of time that it takes to arrive at the home to make the repairs" because that's what x means.

Thus, 35 must be the service fee. This is the upfront fee that is fixed and doesn't change depending on time.

Hope this helps!
