Answer: 2/4 is 1/2   and 2/10 is 2/5 i believe

Step-by-step explanation:

Answer:

7/10

Step-by-step explanation:

Turn 2/4 into 20/40 and 2/10 into 8/40. If you add it it is 28/40. Divide both numbers by 4 and you get 7/10

Answer:

80,94º

Step-by-step explanation:

What I've done is, first draw a triangle with a 90º angle and write down the height (324m) and the tourist's distance (100m).

So I calculated the tangent of the angle of the tourist.

The formula is tan=Oposite side/adjacent

[tex]tan=\frac{opposite side}{adjacent}[/tex]

[tex]tan=\frac{324}{100} =3.24[/tex]

And now with your calculator you press "shift" and "tan". Then introduce 3,24 and it will give you the result (80,94º).

I hope it helped.

Answer:

1 1/4

Step-by-step explanation:

5/6 plus 1/3 plus 1/12 is the same as 10/12 plus 4/12 plus 1/12 which equals 15/12, which is also 1 3/12, and that reduced is 1 1/4

it's 5/4 i'm b0red so i'm answering what I want

Answer:

252,000

Step-by-step explanation:

since we know that 5% of 240,000 is 12,000

then we just add 12,000 to the 240,000 for a 5% increase

Answer:

Mode

Step-by-step explanation:

29 occurs 3 times

Step-by-step explanation:

MEAN

add up all the numbers, then divide by how many numbers there are.

26+29+29+17+33+24+32+24+21+29/10

264/10

132/10 or 26.4

RANGE

The Range is the difference between the lowest and highest values.

lowest value: 17

highest value: 33

33-17= 16

MEDIAN

Arrange your number in numerical order:

17, 21, 24, 26, 29, 29, 29, 32, 33

Count how many numbers you have: 10

Since it's an even number divide 10 by 2: 5

Go to the number in that position and average it with the number in the next higher position to get the median.

5th position: 26

6th position: 29

26+29/ 2= 27.5

Therefore, the median is 27.5

MODE

To find the mode, or modal value, it is best to put the numbers in order. Then count how many of each number. A number that appears most often is the mode.

17, 21, 24, 24, 26, 29, 29, 29, 32, 33

Therefore, thee mode is 29

Answer:

Step-by-step explanation:

Given equation of the line is,

y = 2x + 1

By comparing this equation with the slope-intercept form of the equation,

y = mx + b

m = Slope of the line = 2

b = y-intercept = 1

Table for the input - output values,

x        -1            0            1            2

y        -1            1             3           5  

Now graph these points on the graph and join them by a straight line.

Answer:

3y^2-14y+8

Step-by-step explanation:

Remember FOIL

First

Inner

Last

(3y-2)(y-4)

Answer:

Step-by-step explanation:

Use FOIL method

(3y - 2 )(y - 4) = 3y*y - 4*3y  + y *(-2) - 4 * (-2)

                      =3y² - 12y - 2y + 8          {Combine like terms}

                      = 3y² - 14y + 8

Answer:

$9.20

Step-by-step explanation:

Mixed nuts = 1/5

Chocolate candies = 1/2

Granola = 1 1/4

Cost of the trail mix

Mixed Nuts $2.50

Chocolate Candies $3.40 Granola $5.60

= 1/5 * 2.50 + 1/2 * 3.40 + 1 1/4 * 5.60

= 0.5 + 1.7 + 7

= $9.20

Answer: A loss of $35,100

Step-by-step explanation:

The tractor had cost $136,000 and had accumulated a depreciation of $69,900.

This means that the net book value of the tractor was:

= 136,000 - 69,900

= $66,100

The insurance company was supposed to give them this amount but instead gave them $31,000. They will therefore suffer a loss of:

= 66,100 - 31,100

= $35,100

Answer:

m∠ACD = 24°

Step-by-step explanation:

Measure of the interior angles of a polygon = [tex]\frac{(n - 2)\times 180}{n}[/tex]

Therefore, measure of the interior angles of a rectangle = [tex]\frac{(4 - 2)\times 180}{4}[/tex]

                                                                                              = [tex]\frac{360}{4}[/tex]

                                                                                              = 90°

m∠BCD = 90°

Since, m∠BCD = m∠BCA + m∠ACD

90° = 66° + m∠ACD

m∠ACD = 90° - 66°

              = 24°

Therefore, measure of angles ACD is 24°.

Answer: 64

Step-by-step explanation:

To score an average of 60 in the three tests, the total score of the test should be: = 60 × 3 = 180

Since the student already has scores of 52 and 64, the score in the third test will be:

= 180 - (52 + 64)

= 180 - 116

= 64

Answer:

One eighth

Step-by-step explanation:

By multiplying each fraction by 100, you can get the percentage.

(1/8) x 100 = 12.5

(5/4) x 100 = 125

(16/25) x 100 = 64

Answer:

A

Step-by-step explanation:

100 / 12,5 = 8

12,5% = 1/8
