Answer:

1394

Step-by-step explanation:

Set up equation to find the number:

Variable n = number

65/100 = 1105/n

Cross multiply:

65 × n = 100 × 1105

65n = 110,500

n = 1700

Check your work:

1700 × 65%

Convert percentage into decimal:

1700 × 0.65

1105

Correct!

Find 82% of 1700:

Variable x = 82% of 1700

82/100 = x/1700

82 × 1700 = 100 × x

139,400 = 100x

1394 = x

Check your work:

1700 × 82%

1700 × 0.82

1394

Correct!

The 82% of the original number (1700) is approximately 1394.

Let's denote the original number as N. We know that 65% of N is equal to 1105. We can write this as:

65% of N = 0.65 * N = 1105

Now, to find the value of N, we can rearrange the equation to solve for N:

N = 1105 / 0.65

Now, calculate the value of N:

N ≈ 1700

So, the original number N is approximately 1700.

Next, we need to find 82% of this number. We can express this as:

82% of N = 0.82 * N

Now, substitute the value of N:

82% of 1700 = 0.82 * 1700

                     ≈ 1394

Thus, 82% of the original number (1700) is approximately 1394.

To summarize, first, we found the value of the original number (N) using the given information that 65% of N is equal to 1105. Then, we calculated 82% of N, which turned out to be approximately 1394.

Answer: Rs. 35,000

Step-by-step explanation:

The taxable income is:

= Yearly income - Tax exemption

= 500,000 - 150,000

= Rs. 350,000

The tax on the first Rs. 2,000,000 is 10% which means that tax is:

= 350,000 * 10%

= Rs. 35,000

Answer:

y = -x + 1

Step-by-step explanation:

Explanation:

Each equation given to you is in y = mx+b form (aka slope intercept form).

The slope m is what we'll focus on.

The first equation has slope of 1, while the second equation has slope -1.

The two slopes multiply to -1. This is a property of any pair of perpendicular lines, as long as neither line is vertical nor horizontal.

Or you could note that -1 is the negative reciprocal of 1, or vice versa.

So there are a few options to see why the lines are perpendicular.

Answer:

3p−4q+r) is (p + 7q - 6r)(p+7q−6r) less than (4p+3q-5r)(4p+3q−5r) .

Let (3p-4q+r)(3p−4q+r) is 'x' less than (4p+3q-5r)(4p+3q−5r) . Then

3p-4q+r = 4p+3q-5r - x→3p−4q+r=4p+3q−5r−x

x= 4p+3q-5r - (3p-4q+r)→x=4p+3q−5r−(3p−4q+r)

x= 4p+3q-5r - 3p + 4q - r→x=4p+3q−5r−3p+4q−r

x= 4p- 3p +3q +4q - 5r - r→x=4p−3p+3q+4q−5r−r

x= p + 7q - 6r→x=p+7q−6r

Thus (3p-4q+r)(3p−4q+r) is (p + 7q - 6r)(p+7q−6r) less than (4p+3q-5r)(4p+3q−5r) .

Answer:

5p+3q-6r

Step-by-step explanation:

4p+3q-5r -(3p-4p+r) = 4p+3q-5r-3p+4p-r = 5p+3q-6r

if u made a typo and the question is "How much is 3p-4q+r less than 4p+3q-5r", the answer is p+7q-6r​

Second Option

Step-by-step explanation:

We need to graph the equation

The -1 represent the y intercept. So our y intercept will be at (0,-1).

We then would move up 2 and right 3 units because that represent our slope. So the second option.

Answer:

A = 10

Step-by-step explanation:

Use formula: c = sqrt of a^2 + b^2

1) Put in known numbers:

26 = sqrt of a^2 + 24^2

But instead of adding you would subtract and rearrange the formula bc you already have C:

2) Solve:

A = sqrt of 26^2 - 24^2

A = sqrt of 676 - 576

A = sqrt of 100

A = 10

Sqrt: square root

Answer:

Number of bottles in each box = 8

Step-by-step explanation:

Given:

Number of boxes = 12 boxes

Number of bottle in each box = n

Number of bottle remove = 12

Number of bottle remain = 84

Find:

Number of bottles in each box.

Computation:

Total bottle = (Number of boxes)(Number of bottle in each bo)

Total bottle = 12n

12n = 12 + 84

12n = 96

n = 8

Number of bottles in each box = 8

Answer:

The number of bottles in each box is 8.

Step-by-step explanation:

Number of boxes =  a dozen = 12

Number of bottles in each box = n

Total number of bottles = n x 12 = 12 n

12 bottles are removed

number of bottles

12 n - 12 = 84

12 n = 96

n = 8

So, the number of bottles in each box is 8.

No, because they are parallel.

Step-by-step explanation:

The lines [tex]p[/tex] and [tex]m[/tex] will not intersect, so Kevin is not correct.

It is given that planes A and B intersects. The plane A contains the line p, m and n on its plane. The lines p and m are parallel to each other. They are identical and move in the same direction.

Since the line p and m are parallel, they will not meet each other at any point because parallel lines does not intersect or meet at a point, they run parallelly along each other.

So, line p and m will not intersect.

Thus the answer is " No, because they are parallel."
