Answer:

Dan is correct

Step-by-step explanation:

First, I calculated the amount of hours that the graph shows in total, coming up with a total of 3,085 hours. I do this by multiplying the number of adults surveyed by the number of hours they spent. So for the first column, (80+70)*1, second column, (90+80)*2, third column, (135+130)*3, fourth column, (140+135)*4, and fifth column, (65+75)*5 if you get what I mean. Then I add up all values. Knowing that there were two sets of 500 American adults interviewed already, I came to the conclusion that 1,000 total adults were surveyed. Finally, I divided the total number of hours(3,085) by the total number of adults interviewed (1,000) to get a mean of 3.085 hours, rounding it to 3 hours and proving that Dan is correct.

Answer:

B) 74

Step-by-step explanation:

This is an icoseles triangle because of the 2 lines in each side. This makes <Y equal to <Z

Given:

<Y = <Z

All triangle angles add up to 180 so:

<W + <Y + <Z = 180

<W + 53 + 53 = 180

<W + 106 = 180

<W = 180 - 106

<W = 74

Option A "4, 6, 8".

This is because when we multiply 2x2, we get 4, then we add +2 with 4, we get 6, then we add again +2 with 6, we get 8. So, a list of three square numbers is completed.

Therefore, Option A is the correct answer.

Answer:

Inductive reasoning is the opposite of deductive reasoning. Inductive reasoning makes broad generalizations from specific observations. Basically, there is data, then conclusions are drawn from the data. ... Even if all of the premises are true in a statement, inductive reasoning allows for the conclusion to be false.

Step-by-step explanation:

11 7/8 can be written as (11 + 7/8). If we find (11+7/8)², we know that √(11+7/8)² = (11+7/8), so we can compare (11+7/8)² with 129 and see which is bigger.

(11+7/8)² = (11+7/8) * (11+7/8)

= 121 + 7/8 * 11 + 7/8 * 11 + (7/8)²

= 121 + 77/8 + 77/8 + (7/8)²

77/8 is greater than 9 (8*9 = 72) but less than 10 (8*10=80). Rounding down to 7, we have

121 + 7 + 7 + (7/8)²

= 135 + (7/8)²

Even when rounding down, (11+7/8)² is greater than 129. Therefore,

129 < (11+7/8)²

square root both sides

√129 < (11+7/8)

We can apply a similar process for the next one.

(3+5/6)² = (3+5/6) * (3+5/6)

= 9 + 5/6 * 3 + 5/6 * 3 + (5/6)²

= 9 + 15/6 + 15/6 + (5/6)²

15/6 is less than 3 (6*3 = 18) but greater than 2 (6*2 = 12). Rounding down to 2, we have

9 + 2 + 2 + (5/6)²

= 13 + (5/6)² > 10

Even when rounding down, (3+5/6)² is greater than 10

(3+5/6)² > 10

square root both sides

(3+5/6) > √10

We have that the total length of paper needed to cover all the tables is

[tex]X=288.5ft[/tex]

From the question we are told that:

Number of tables [tex]n=36[/tex]

Length of table[tex]l=8[/tex]

Extension [tex]e=3 inch =>0.25feet[/tex]

Generally, the equation for the Total length  tables is mathematically given by

[tex]l_t=n*l\\\\l_t=36*8[/tex]

[tex]l_t=288ft[/tex]

Therefore with an extension of 0.25ft at both end we have the Total length of  tablecloths to be

[tex]X=l_t+2(e)\\\\X=288ft+2(0.25)[/tex]

[tex]X=288.5ft[/tex]

In conclusion

The total length of paper needed to cover all the tables is

[tex]X=288.5ft[/tex]

Answer:

n(number of tiles) x 3 - 2

Step-by-step explanation:

times mean multiplication and minus mean subtraction, I hope this helps.

An equation is formed of two equal expressions. An equation that fits Sarah's way of seeing the relationship is y = 3x - 2.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

As stated by Sarah that "the number of tiles in each figure was always 3 times the step number minus 2", this can be written in the form of an equation as shown below.

Number of tiles = [3 × (Number of steps)] - 2

Assume that the number of tiles is represented by y, while the number of steps can be written as x. Therefore, we can write the equation as,

y = 3x - 2

Now, let's check the equation,

When the number of steps is 3, the number of tiles is 7.

y = 3(3) - 2

y = 9 - 2

y = 7

Since the number of tiles is the same, therefore, the equation is correct.

Hence, an equation that fits Sarah's way of seeing the relationship is y = 3x - 2.

Answer:

The answer is 134.61

Step-by-step explanation:

We have, 26% × x = 35

Or, 26/100 × x = 35

We have: x = 35 × 100/26

35×100 = 3,500

3,500 ÷ 26 = 134.61

x = 134.61

If you use a calculator, simply put 35×100÷26, which will give you the answer.

Answer:

5

Step-by-step explanation:

Solution is 8 in

Let´s call dimensions of the box

According to the problem statement

y = x + 3     and    h = 4 in

The volume of the box is:

V = x×y×h       V = 360 in³

Then  V = x × ( x + 3 ) × 4     ( by substitution of y as a function of x )

360 = x × ( x + 3 ) × 4

Simplifying by 4

90 =  x × ( x + 3 )

90 = x² + 3x

We got a second degree equation, solving for x

x² + 3×x - 90 = 0

x₁,₂ = ( -3 ± √ (3)² + 4×90 )/2   ⇒   x₁,₂ = ( - 3 ± 19,21 )/2

x₁   ⇒  is a negative value    x = - 11,1  so we dismiss such solution

x₂  = 16.21/2

x₂  =  8.1 in

rounding to the nearest integer number we get the value for the length f the box

x₂ = 8 in        ⇒ x = 8 in
