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

t him. Ten minutes later, Amir still had .25 of a mile to go before he reached the meeting g place, but sal was .75 of a mile beyond it. If Amir is running at a faster pace,6.7 mph, to neared hundredth of an hour, after how much time will Amir catch up to sal

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

Which graph has the same end behavior as the graph of f(x) = –3x3 – x2 + 1?
Zina [11190]
Without specific options available, I can provide guidance on where to focus your attention.

The end behavior of a function refers to how the graph behaves (upwards or downwards) as it nears positive or negative infinity within its domain. Essentially, we’re investigating the direction the graph tends towards on both sides.

In this scenario, as the value of x grows, the graph descends, while it ascends when x diminishes. Seek out a comparable occurrence.

A triangle has sides that measure 4 units, 6 units, and 7.21 units. What is the area of a circle with a circumference that equal
PIT_PIT [11075]

Step-by-step explanation:

Given are

Sides of the triangle measure 4 units, 6 units, and 7.21 units.

We need to compute the area of a circle whose circumference matches the triangle's perimeter.

The triangle's perimeter corresponds to the circle's circumference.

4 + 6 + 7.21 = 2πr, where r is the radius of the circle.

r = 2.73 units

Circle's area is:

A=\pi r^2\\\\A=3.14\times (2.73)^2\\\\A=23.402\ \text{units}^2

or

A = 24 square units

Thus, the circle’s area is 24 square units.

To reduce wear and tear on the family vehicle, you decide to rent a car. Happy Harry’s Rentals has a $500 fee for any rental up
Inessa [11141]
Assuming a maximum rental duration of 8 days, if we apply this to the equation, Happy Harry's Rentals costs $500, while Smilin' Sam's charges $600. Therefore, for the 7th and 8th days, Happy Harry's Rentals is a better option, while Smilin' Sam's is preferable for the first six days.

At a certain company, loan agents are paid based on the number of loans they close in a day. Based on company records, the numbe
Zina [11190]

Answer:

C. The mean daily salary is not above $350 per day

Step-by-step explanation:

The calculation is displayed below:

Y = a + bX

where,

Y = earnings of a randomly chosen agent

a = $150

b = $50

X = number of loans closed

Now

E(x) = (1 × 0.05) + (2 × 0.10) + (3 × 0.22) + (4 × 0.30) + (5 × 0.18) + (6 × 0.12) + (7 × 0.03)

= 3.94

Consequently,

E(y) = $150 + ($50 × 3.94)

= $347

therefore, option C is incorrect
