Simplify the expression. 1.7 – 2.7 – 1.34 + 4.9 – 1.48
explain im lost

Answers

Answer 1

Answer:

0.08

Step-by-step explanation:

1.7 – 2.7 – 1.34 + 4.9 – 1.48

 2.7

- 1.7       (subtract 1.7 from 2.7)

--------

-1.0      [2.7 is greater than 1.7 and 2.7 is negative(in the ques) , therefore  1.0 is negative]

-1.0-1.34

we know that  (-) (-) is (+)

therefore add -1.34 with -1.0

   1.34

+  1.0

-----------

  -2.34 [since 1.34 is greater and it is negative]

-2.34+4.9

we know that (-)(+) is (-)

therefore subtract -2.34 from 4.9

  4.90  ← (we put zero so that we can subtract without getting confused)

-  2.34

------------

  1.56 [1.56 is positive because 4.9 is greater and it is positive]

1.56-1.48

here, digit before the decimal point is same but  after decimal point .56 is greater than .48  therefore subtract 1.48 from 1.56

  1.56

-  1.48

-----------

  0.08

therefore,  1.7 – 2.7 – 1.34 + 4.9 – 1.48 = 0.08

hope it helps you!

The Quik-Clean Car Wash charges $15 for a car wash plus $2.50 per gallon for unleaded gasoline. The Mighty Clean Car Wash charges $10 for a carwash plus $2.75 per gallon for unleaded gasoline. Josh is comparing the cost of having his car wash plus filling up his tank with gas at each business. How many gallons of gas would he need to purchase for the cost to be the same at each car wash?

Answers

Answer:

Josh would need to purchase 20 gallons of gas for the cost to be the same at each car wash

Step-by-step explanation:

We need to model both car wash's costs. The Quik-Clean Car Wash charges $15 for a car wash plus $2.50 per gallon for unleaded gasoline. If x is the number of gallons of unleaded gasoline. the total charges of this store are:

C1=15+2.5*x

The Mighty Clean Car Wash charges $10 for a carwash plus $2.75 per gallon for unleaded gasoline. Following the same procedure, their costs are:

C2=10+2.75*x

Josh wants to know how many gallons of gas will make both businesses charge the same. Equating both equations:

15+2.5*x=10+2.75*x

Simplifying:

-0.25x=-5

Solving:

x=-5/(-0.25)=20

Josh would need to purchase 20 gallons of gas for the cost to be the same at each car wash

Fun Zone charges an entrance fee

Town charges $0.40 per ticket and a
$5.00 entrance fee. How many
tickets must be purchased in order
for the total to be the same at both
Fun Zone and Happy Town?

Answers

Answer:

2 tickets

Step-by-step explanation:

To be the same they must equal each other.

4.50 + 0.65x = 0.40x + 5

isolate the variable

subtract 4.50 from both sides

0.65x = 0.40x + 0.50

subtract 0.40x from both sides

0.25x = 0.50

divide both sides by 0.25

x = 0.50 ÷ 0.25

x = 2

Match each circular flower bed on the left to its circumference and its area on the right. Some answer options on the right will not be used.

Answers

Answer:

Bed A --- Third Option

Bed B --- Fifth Option

Step-by-step explanation:

Flower Bed A)

The formula for circumference is:

[tex]C=2\pi r[/tex]

The diameter of A is 10 feet. So, its radius is 5 feet.

Substitute 5 for r. So, the circumference of Bed A is:

[tex]C=2\pi (5)=10\pi\text{ feet}[/tex]

The formula for the area of a circle is:

[tex]A=\pi r^2[/tex]

Substitute 5 for r:

[tex]A=\pi (5)^2[/tex]

Square and simplify:

[tex]A=25\pi \text{ square feet}[/tex]

So, the circumference of Bed A is 10π feet and its area is 25π square feet.

Therefore, match Bed A to the third option.

Flower Bed B)

The radius of Bed B is 6 feet. Again, we can use the circumference and area formulas. Substitute 6 for r for circumference:

[tex]C=2\pi (6)[/tex]

Multiply:

[tex]C=12\pi\text{ feet}[/tex]

Substitute 6 for r for the area formula:

[tex]A=\pi(6)^2[/tex]

Square and simplify:

[tex]A=36\pi\text{ square feet}[/tex]

So, Bed B has a 12π feet circumference and a 36π square feet area.

Therefore, match Bed B to the fifth option.

And we're done!

1. A specialty shop sells gift baskets that contain three different types of
candles: tapers, pillars, and jar candles. Tapers cost $1 each, pillars cost $4
each, and jar candles cost $6 each. Each basket contains 8 candles costing
a total of $24, and the number of tapers is equal to the number of pillars
and jar candles combined. Which system of equations represents the
situation, where t is the number of tapers, p is the number of pillars, and jis
the number of jar candles? *

Answers

Answer:

Option (B)

Step-by-step explanation:

Let the number of tapers in the basket = t

Number of pillars = p

And the number of jar candles = j

Tapers cost = $1 each

Jar candles cost = $6 each

Pillars cost = $ 4

Total number of candles in the basket = 8

Therefore, equation will be,

p + t + j = 8 -----(1)

Cost of the candles in the basket = $24

$1t + $4p + $6j = $24

t + 4p + 6j = 24 -------(2)

Since number of tapers is equal to the number of pillars and jar candles combined,

t = p + j

t - p - j = 0 ------(3)

Therefore, Option (B) is the answer.

Maggie's brother is 6 years younger than four times her age. The sum of their ages is 69.
How old is Maggie?

Answers

Answer:

15

Step-by-step explanation:

If Maggies age is, for example, x, we can say that her brothers age is 4x-6. We know from the problem that Maggies age (x) plus her bothers age, (4x-6) is 69. So,

4x-6+x=69

5x-6=69

5x=75

x=15

So, Maggie is 15.

Answer: Maggie is 15 years old

Step-by-step explanation:

69 = (4m - 6) + m     --- get an equation

69 - m = 4m - 6        --- lets subtract  m from both sides first

75 - m = 4m              --- add 6 on both sides

75 = 5m                    --- add m on both sides

15 = m                       --- divide by 5 on both sides

m = 15, so Maggie is 15 years old

Let's check:

69 = (4(15)-6) +15

69 = (60 - 6) + 15

69 = 54 + 15

69 = 69

I am a rather elderly man. The nature of my avocations for the last thirty years has brought me into more than ordinary contact with what would seem an interesting and somewhat singular set of men, of whom as yet nothing that I know of has ever been writtenI mean the law-copyists or scriveners. I have known very many of them, professionally and privately, and if I pleased, could relate divers histories, at which good-natured gentlemen might smile, and sentimental souls might weep. But I waive the biographies of all other scriveners for a few passages in the life of Bartleby, who was a scrivener of the strangest I ever saw or heard of. While of other law-copyists I might write the complete life, of Bartleby nothing of that sort can be done. I believe that no materials exist for a full and satisfactory biography of this man. It is an irreparable loss to literature. Bartleby was one of those beings of whom nothing is ascertainable, except from the original sources, and in his case those are very small. What my own astonished eyes saw of Bartleby, that is all I know of him, except, indeed, one vague report which will appear in the sequel.Ere introducing the scrivener, as he first appeared to me, it is fit I make some mention of myself, my employees, my business, my chambers, and general surroundings; because some such description is indispensable to an adequate understanding of the chief character about to be presented. Imprimis: I am a man who, from his youth upwards, has been filled with a profound conviction that the easiest way of life is the best. Hence, though I belong to a profession proverbially energetic and nervous, even to turbulence, at times, yet nothing of that sort have I ever suffered to invade my peace. I am one of those unambitious lawyers who never addresses a jury, or in any way draws down public applause; but in the cool tranquility of a snug retreat, do a snug business among rich men's bonds and mortgages and title-deeds. All who know me, consider me an eminently safe man. The late John Jacob Astor, a personage little given to poetic enthusiasm, had no hesitation in pronouncing my first grand point to be prudence; my next, method. I do not speak it in vanity, but simply record the fact, that I was not unemployed in my profession by the late John Jacob Astor; a name which, I admit, I love to repeat, for it hath a rounded and orbicular sound to it, and rings like unto bullion.
