The average length of time that three lawn-service mowers operate on a given day is 930 minutes. None of the mowers operates for
AnnZ [12381]

Answer:

The answer is A. 990.

Step-by-step explanation:

To determine the maximum duration that any of the mowers can run.

The three lawn-service mowers have an average operating time of 930 minutes.

Thus, the overall duration for the three lawn mowers is 930\times 30=2790\ minutes.

The shortest time any mower runs is 900 minutes.

To find the longest operating time of any mower:

Let x represent the maximum operating time for any of the mowers.

Since any of the mowers works the longest time.

Consequently, the remaining two mowers operate at the minimum time.

Based on the question:

x+900+900=2790

x+1800=2790

After subtracting 1800 from both sides:

x=2790-1800

x=990.

Thus, the maximum potential operating time for any mower is 990 minutes.

Consequently, the answer is A. 990.

Sal was tired of waiting for Amir to show up at their meeting place, so he started running at an average speed of 4.5 mph withou
babunello [11817]
The total distance separating them is 0.25 + 0.75 = 1 mile

So, when will Amir travel 1 mile more than Sal?
Keep in mind that distance = speed multiplied by time

When will Sal's distance + 1 equal Amir's distance?
d = st
where h = time in hours
4.5h + 1 = 6.7h
Now, let's isolate h
Subtract 4.5h from both sides
1 = 2.2h
Dividing each side by 2.2 gives us
0.454545 = h
rounded to the nearest hundredth is
0.45 hours

- In the following diagram of triangle QRS, QR = 8 and QS = 17. Determine the value of sin Q. Show how you
PIT_PIT [12445]

Response:

SinQ=\frac{15}{17}

Step-by-step explanation:

We create the right triangle as illustrated in the attached image.

Δ QRS

Here, R represents the right angle

Given

QR = 8

QS = 17

Using the Pythagorean Theorem, we can determine RS:

QR^2+RS^2=QS^2\\8^2+RS^2=17^2\\RS^2=17^2-8^2\\RS^2=225\\RS=\sqrt{225}\\RS=15

Currently, the Sine ratio is known as:

Sin(\theta)=\frac{Opposite}{Hyotenuse}

Where \theta signifies the angle (in this case, angle Q)

The side opposite is RS (which measures 15)

While the hypotenuse is QS (which equals 17)

At this point,

SinQ=\frac{15}{17}

This is the value of SinQ.

We don't require the angle, so we will conclude here.

The table shows the height of water in a pool as it is being filled. A table showing Height of Water in a Pool with two columns
zzz [12365]

Answer:

The water level rises 2 inches for each minute.

Step-by-step explanation:

The slope indicates the rate of height change

m = (16 - 12)/(4 - 2) = 4/2 = 2

2 inches per minute

A positive slope signifies an increase
