When thay get to school, Sasha has walked for 0.6 hour and Hannah has walked 0.45 hour. What is the rate in kilograms per hour at which they walked to school

Answers

Answer 1

Answer:

4 km/hr

Step-by-step explanation:

Sasha walks at a constant rate. She meets her friend Hannah 0.6 kilometer along the way, and they continue walking at the same constant rate. When thay get to school, Sasha has walked for 0.6 hour and Hannah has walked 0.45 hour.

Let

the rate of the speed at which they walked to school be represented by r

Distance to school for Sasha = Distance to school for Hannah

Distance = Speed (rate × time)

Hence:

0.6r = 0.45r + 0.6

Collect like terms

0.6r - 0.45r = 0.6

0.15r = 0.6

r = 0.6/0.15

r = 4 km/hr

The rate in Kilometer per hour at which they walked to school is 4km/hr

The scale of a model train is 1 1 inch to 13.5 13.5 feet. One of the cars of the model train is 5 5 inches long. What is the length, in feet, of the actual train car?

Answers

Answer:

74.25feet

Step-by-step explanation:

Given the scale of a model train expressed as;

1in = 13.5feet

We are to express length of 5.5in in feet

5.5in = x

Divide both expressions

1/5.5 = 13.5/x

Cross multiply

1×x = 5.5× 13.5

x = 74.25feet

Hence the actual length of the car in feet is 74.25feet

7x + 5 = 3(2x + 3) + x - 4

Answers

Answer:

Infinite Many Solutions

0 = 0

Step-by-step explanation:

7x + 5 = 3(2x + 3) + x - 4 (Given)

7x + 5 = 6x + 9 + x - 4 (Distributive Property Of Equality)

7x + 5 = 7x + 5 (Combine Like Terms)

0 = 0 (Subtraction Property Of Equality)

As you see it's the same thing in both sides and if you solve it gives 0 = 0 because it would cancel each other out and since 0 is equal to 0 it's infinite many solutions.

a solution for y = x + 2

Answers

There is an infinite number of solutions.

Y = x + 2

You could replace Y with 4 and X with Y-2 (which is 2 in this case. 4-2=2).

The result would look like this:

4 = 2 + 2

Y = x + 2

Y = 4

x = 2

from the adjoining figure, find the value of x

Answers

Answer:

x = 2°

Step-by-step explanation:

x + 2x + 30 = 180°

3x + 30 = 180°

3x = 180°/30°

3x = 6°

x = 6°/3°

153.9 inches is the correct answer

Answer:

153.9 in²

Step-by-step explanation:

Using the formula: A = π r²

Where r = the radius and π is 3.14.

The radius is the diameter divided by 2.

14 divided by 2 is 7.

Plug in 7 into the formula:

A = π 7²

7² is 49.

49 times π is equal to 153.86.

Rounding this up to the nearest tenth, you'll get 153.9

. Christian made $138,000 as a Physician Assistant. Social Security tax is to a maximum income of $128,400. The Medicare tax is 1.45% and the Social Security tax rate is 6.2%. How much did Christian pay in FICA taxes?

Answers

Answer:

Total money made as a physician = $138,000

Medicare tax = 1.45% of $138,000

= 1.45/100 * $138,000 = $2001

security tax = 6.2 %of $138,000

= 6.2/100 * $138,000 = $8556

= $138,000 - ($2001 + $8556)

$138,000 - $10557

= $127,443 is paid by Christian in FICA taxes

Step-by-step explanation: Since the equation of this line is written in

slope-intercept or y = mx + b form, its slope or m is represented by the

coefficient of the x term which in this case is 8/5.

It's y-intercept or b is represented by

the constant term which in this is -5.

To graph the line, start with the y-intercept of -5.

So go down 3 units on the y-axis, plot a point at (0, -3).

From there, take your slope of 8/5, so rise 8 units

and run 5 units the right which should leave you at (5, 3).

Graph the line through those points.

Answers

Answer:

$2075

Step-by-step explanation:

commission = 0.02 x $25,000 = $500

The remainder = $130,000 - $25,000 = $105,000

Commission on the remainder = 0.015 x $105,000 = $1,575

Total commission = $1,575 + $500 = $2075

Salutary neglect was..A. when the British just ignored the colonies and they got used to governing themselvesB. when the British tightly controlled the coloniesC. a British attempt to help the colonies move into the west From Chapter 9: Of Their Voyage, and How They Passed the Sea; and of Their Safe Arrival at Cape Cod (September, 1620)1Start of paragraph 1 of 13In sundry of these storms the winds were so fierce and the seas so high, as they could not bear a knot of sail, but were forced to hull for divers days together. And in one of them, as they thus lay at hull in a mighty storm, a lusty young man called John Howland, coming upon some occasion above the gratings was, with a seele of the ship, thrown into sea; but it pleased God that he caught hold of the topsail halyards which hung overboard and ran out at length. Yet he held his hold (though he was sundry fathoms under water) till he was hauled up by the same rope to the brim of the water, and then with a boat hook and other means got into the ship again and his life saved. And though he was something ill with it, yet he lived many years after and became a profitable member both in church and commonwealth. In all this voyage there died but one of the passengers, which was William Butten, a youth, servant to Samuel Fuller, when they drew near the coast.2Start of paragraph 2 of 13....3Start of paragraph 3 of 13Being thus arrived in a good harbor, and brought safe to land, they fell upon their knees and blessed the God of Heaven who had brought them over the vast and furious ocean, and delivered them from all the perils and miseries thereof, again to set their feet on the firm and stable earth, their proper element. And no marvel if they were thus joyful, seeing wise Seneca was so affected with sailing a few miles on the coast of his own Italy, as he affirmed, that he had rather remain twenty years on his way by land than pass by sea to any place in a short time, so tedious and dreadful was the same unto him.4Start of paragraph 4 of 13But here I cannot but stay and make a pause, and stand half amazed at this poor people's present condition; and so I think will the reader, too, when he well considers the same. Being thus passed the vast ocean, and a sea of troubles before in their preparation (as may be remembered by that which went before), they had now no friends to welcome them nor inns to entertain or refresh their weatherbeaten bodies; no houses or much less towns to repair to, to seek for succor. It is recorded in Scripture as a mercy to the Apostle and his shipwrecked company, that the barbarians showed them no small kindness in refreshing them, but these savage barbarians, when they met with them (as after will appear) were readier to fill their sides full of arrows than otherwise. And for the season it was winter, and they that know the winters of that country know them to be sharp and violent, and subject to cruel and fierce storms, dangerous to travel to known places, much more to search an unknown coast. ...5Start of paragraph 5 of 13From Chapter 11: The Starving Time (Winter, 16201621)6Start of paragraph 6 of 13But that which was most sad and lamentable was, that in two or three months' time half of their company died, especially in January and February, being the depth of winter, and wanting houses and other comforts; being infected with the scurvy and other diseases which this long voyage and their inaccommodate condition had brought upon them. So as there died some times two or three of a day in the foresaid time, that of 100 and odd persons, scarce fifty remained. And of these, in the time of most distress, there was but six or seven sound persons who to their great commendations, be it spoken, spared no pains night nor day, but with abundance of toil and hazard of their own health, fetched them wood, made them fires, dressed them meat, made their beds, washed their loathsome clothes, clothed and unclothed them. In a word, did all the homely and necessary offices for them which dainty and queasy stomachs cannot endure to hear named; and all this willingly and cheerfully, without any grudging in the least, showing herein their true love unto their friends and brethren; a rare example and worthy to be remembered. Two of these seven were Mr. William Brewster, their reverend Elder, and Myles Standish, their Captain and military commander, unto whom myself and many others were much beholden in our low and sick condition. And yet the Lord so upheld these persons as in this general calamity they were not at all infected either with sickness or lameness. ... Use the factorial operation to evaluate 10!.
