it takes 18.75 to reach 7,500

Answer:

x=30h

Step-by-step explanation:

First, you need to figure out how much she actually paid for lessons, so you need to subtract 45 from 165.

165-45=120

Now you know she paid 120 dollars in total for lessons.

You know she took four hours of lessons, so you divide 120 by 4.

120/4=30

It takes $30 an hour for lessons.

Now you can form an equation.

Since you know it takes $30 per hour of lessons, it will be 30h.

x is the full amount of money paid

You don't need to add 165-45 to your equation because not everyone will need to rent skis when they come to White Peaks.

Hope this helps!

x=30h is the equation used to find how much White Peaks charges, h, for each hour of group skiing lessons.

A fixed charge is any type of expense that recurs on a regular basis, regardless of the volume of business.

First, we need to find out how much she actually paid for lessons, so we need to subtract 45 from 165.

165-45=120

Now we know that she paid 120 dollars in total for lessons.

Given that she took four hours of lessons, divide 120 by 4 to get the fixed charge of a lesson.

120/4=30

It takes $30 an hour for lessons.

Now we can form an equation.

Since it takes $30 per hour of lessons, it will be 30h.

x is the full amount of money paid.

No need to add 165-45 to equation because not everyone will need to rent skis when they come to White Peaks.

Hence, the equation formed to find the cost of each ession is x=30h

Answer:

  24 square units

Step-by-step explanation:

For such questions it is convenient to choose the "base" to be a segment that is aligned with one of the coordinate axes. Here, the horizontal segments will serve. Their length is the difference between the x-coordinates of the end points, -2 -(-6) = 4, for example.

The height is measured perpendicular to the base, so will be the difference between the y-coordinates of the horizontal segments: 2 -(-4) = 6.

The area is given by the formula ...

  A = bh

  A = 4·6 = 24 . . . square units

hello!

the answer to your question is 41!

-----------

explanation:

- Step 1: Our output value is 100.

- Step 2: We represent the unknown value with [tex]x[/tex].

- Step 3: From step 1 above, [tex]100 = 100%[/tex]%

- Step 4: Similarly, [tex]x = 41%[/tex]%

- Step 5: This results in a pair of simple equations:

[tex]100 = 100% (1)[/tex]% (1)

[tex]x=41[/tex]% (2)

- Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both  equations have the same unit (%); we have

[tex]\frac{100}{x}[/tex] = [tex]\frac{100}{41}[/tex]

- Step 7: Again, the reciprocal of both sides gives

[tex]\frac{x}{100}[/tex] = [tex]\frac{41}{100}[/tex]

Therefore, 41% of 100 is 41.

Answer:

81=5+b, 81-5=b, 81-b=5

Step-by-step explanation:

We can write the equation in terms of 81, b, or 5. Let's first start by writing it in terms of 81. We are already given that 5+b=81 therefore...

5+b=81 OR 81=5+b (transitive property)

Now, let's write the equation in terms of b.

5+b=81

Subtract 5 from both sides (subtraction property of equality)

5-5+b=81-5

b=81-5 OR 81-5=b (transitive property)

Lastly, let's write the equation in terms of 5.

5+b=81

Subtract b from both sides (subtraction property of equality)

5+b-b=81-b

5=81-b OR 81-b=5 (transitive property.

Step-by-step explanation:

Based on percentage composition, the mass of recycled paper in Ophelia’s paper napkins is 203 g.

A percentage gives an amount of a given quantity out of a whole value expressed in 100 units.

The total mass of the napkins = 580 g

b recycled paper in napkin = 35% of 580 g

Then;

The mass of recycled paper = 35/100 * 580 g

mass of recycled paper = 203 g

Therefore, the mass of recycled paper in Ophelia’s paper napkins is 203 g.

Given,

Cost of 35 books Joni bought = Rs. 122,500

So,

Cost of 1 book = [tex]\frac{Rs. 122,500}{35}[/tex]

Now,

Same no. of books that Toni bought = 24

So, cost of 24 books

Answer:

72%

Step-by-step explanation:

1. 53 - 30 = 23 ( under 35 years old plan to go hiking)

2. 23 + 9 = 32 (under 35 years old Total)

3. 83 - 32 = 51 ( 35 years old or over Total)

4. 51 - 30 = 21 ( 35 years old or over Do not plan to go hiking)

5. Total visitors under 35 years old = 32

visitors under 35 years old plan to go on hiking = 23

percentage = (23/32)*100 = 71.8 = 72% approx

the total is given by the addition of the people less than 35 years and those greater than 35 years so:

QUESTION 1:

x+30=53

x=53-30

x=23

QUESTION 2:

9+x=30

x=30-9

x=21

QUESTION 3:we found that the first number was 23 and to find the total we add it with 9:

23+9=32

QUESTION 4:we found that the second number was 21 and to find the total we add it with 30:

21+30=51

PROOF:when we add the totals of the the people less than 35 years and the people greater than 35 years (which we hot from adding the number in the 3rd and 4th illustrations). If our answers are correct it must give us 83,so let add:

32+51=83

IT GAVE US 83 SO OUR ANSWERS ARE CORRECT

and finally to find the percentage we have 53 as the total so:

(23/32)×100%

0.7187×100%

71.87%

and when we round it it gives us 72%

SO OUR FINAL ANSWER IS 72%

Answer:

B, C, D, and F is correct

Step-by-step explanation:

Grouping is done based on the distributive property of multiplication over addition. The factorized form of given polynomial is (8x-1)(7x-1)

Suppose a, b and c are three numbers. Then we have:

[tex]a(b + c) = a\times b + a\times c[/tex]

(a(b+c) means a multiplied to (b+c). The sign of multiplication is usually hidden when using symbols and both quantities which are in multiplication are written together without space)

The given polynomial is [tex]56x^2 - 8x - 7x + 1\\[/tex]

It can be grouped and factored as:

[tex]56x^2 - 8x - 7x + 1 = 8x \times 7x - 8x \times 1 - 7x + 1\\56x^2 - 8x - 7x + 1 = 8x(7x - 1) - 1(7x -1 )\\56x^2 - 8x - 7x + 1 = (7x - 1)(8x - 1) = (8x-1)(7x-1)[/tex]

Thus,

The factorized form of given polynomial is (8x-1)(7x-1)
