A $10 decrease followed by a $15 increase

Same as the original, less than, or greater than the original?​

Answers

Answer 1
That’s not the full question but if it was it would be greater bc 10 - 10=0 but 10-10+15 would equal 15 instead of 10

Answer:

  28 square units

Step-by-step explanation:

The figure can be decomposed several ways. Maybe easiest to see is as a 8×4 rectangle with a 2×4 right triangle cut from the corner.

The area of the rectangle is ...

  A = LW = (8)(4) = 32

The area of the missing triangle is ...

  A = 1/2bh = 1/2(2)(4) = 4

Then the area of the shaded figure is ...

  32 - 4 = 28 . . . square units

_____

Alternate solution

If you divide the figure with a horizontal line across the middle, it becomes a 4×4 square and a trapezoid with bases 2 and 4 and height 4. The shaded area is the sum of these areas.

The area of a trapezoid is ...

  A = 1/2(b1 +b2)h

  A = (1/2)(2 +4)(4) = 12

The area of the square is ...

  A = s² = 4² = 16

Then the total area is ...

  12 +16 = 28 . . . square units

An equation is shown below:
6(2x - 11) + 15 = 3x + 12
Part A: Write the steps you will use to solve the equation, and explain each step. (6 points)
Part B: What value of x makes the equation true? (4 points)

Answers

x = 7
6(2x-11)+15=3x+12
distribute the 6:
12x-66+15=3x+12
add -66 and 15:
12x-51=3x+12
subtract 3x from both sides:
9x-51=12
add 51 to both sides:
9x=63
divide 9 from both sides:
x=7
X=7 hope this helps

Answers

Answer:

8: 73.2 cm

10: 738 mm

Step-by-step explanation:

8: A= 12.2 (4.5 + 7.5) / 2 --> 146.2 / 2 = 73.2 cm

10: A= 36 (22 + 19) / 2 --> 1,476 / 2 = 738 mm

Answer:

8: 73.2

10: 738

Step-by-step explanation:

Area of a trapezoid = [tex]A=\frac{a+b}{2} h[/tex]

where a and b = base lengths and h = height

For #8

These are the given dimensions

Base 1 = 4.5

Base 2 = 7.5

Height = 12.2

All we have to do is plug in the values into the formula

So....

[tex]A=\frac{4.5+7.5}{2} 12.2\\4.5+7.5=12\\\frac{12}{2} =6\\6*12.2=73.2[/tex]

Hence the answer is 73.2cm²

For #10

Once again all we have to do is plug in the values into the formula

[tex]A=\frac{22+19}{2} 36\\22+19=41\\\frac{41}{2} =20.5\\20.5*36=738[/tex]

Hence the answer is 738

Jasraj left his house and walked 1500 m east to the supermarket. He then walked another 500 m east to the comic store before walking back home the same way he came. How many kilometers did Jasraj walk altogether?

Answers

Answer:

Jasraj walked 4 kilometers all together

Step-by-step explanation:

First, add.

1,500 + 500 = 2,000

Then, multiply by 2.

2,000 × 2 = 4,000

Now, we have to convert to kilometers.

1 kilometer = 1000 meters

4,000 ÷ 1,000 = 4

So, Jasraj walked 4 kilometers!

Have a wondeful day! :)

If 30% of a number equals 8, find 90% of that number.

Answers

Answer:

8.88

Step-by-step explanation:

I believe it is 8.88 becuase this question is asking to find 90% pf that number.  

What do you need to do?

you have to make a proportion.

8/x 90/ 100

You would now cross multiply. 90* x = 90x 8*100= 800

the equation you would need is 90x = 800. divide them and you get 8.88.

ROUNDED: you get 9.

I believe this is correct sorry if it was incorrect.

anwser: 8.88

The volume of a right rectangular prism is 70 7/8 cubic feet and its base is a square with a side length of 4 1/2 feet. what is the height?

Answers

Answer:

7/2 feet

Step-by-step explanation:

Volume of Right Rectangular Prism: V = w * h * l

You are given the volume, and the base (which would include l and w)- and are told to find h.

70 7/8 cubic feet = 4 1/2 feet * h * 4 1/2 feet (simplify the right side)

70 7/8 cubic feet = 81/4 feet squared * h (divide both sides by 81/4)

7/2 feet = h

The height will be 7/2

I repeat the challenge, not a single advantage is derived. (Our corn will fetch its price in any market in Europe, and our imported goods must be paid for, buy them where we will.)But the injuries and disadvantages we sustain by that connection, are without number; and our duty to mankind at large, as well as to ourselves, instruct us to renounce the alliance: Because, any submission to, or dependence on Great Britain, tends directly to involve this continent in European wars and quarrels; and sets us at variance with nations, who would otherwise seek our friendship, and against whom, we have neither anger nor complaint. (As Europe is our market for trade, we ought to form no partial connection with any part of it.) It is the true interest of America to steer clear of European contentions, which she never can do, while by her dependence on Britain, she is made the make-weight in the scale of British politics.Europe is too thickly planted with kingdoms to be long at peace, and whenever a war breaks out between England and any foreign power, the trade of America goes to ruin, BECAUSE OF HER CONNECTION WITH ENGLAND. (The next war may not turn out like the last, and should it not, the advocates for reconciliation now, will be wishing for separation then, because, neutrality in that case, would be a safer convoy than a man of war.) Every thing that is right or natural pleads for separation. The blood of the slain, the weeping voice of nature cries, 'TIS TIME TO PART. Even the distance at which the Almighty hath placed England and America, is a strong and natural proof, that the authority of the one, over the other, was never the design of Heaven. (The time likewise at which the continent was discovered, adds weight to the argument, and the manner in which it was peopled increases the force of it.) The reformation was preceded by the discovery of America, as if the Almighty graciously meant to open a sanctuary to the Persecuted in future years, when home should afford neither friendship nor safety.
