Answer:

162

Step-by-step explanation:

Answer: 162

Step-by-step explanation:

The formula for this is lxw (length x width) so just multiply 6 by 27 which gives you 162.

Answer:

-2.25 + 1 1/10 = -1.15

-2.25 + 1 2/10 = -1.05

-2.25 + 1 3/10 = -0.95

-2.25 + 1 4/10 = -0.85

-2.25 + 1 5/10  = -0.75

-2.25 + 1 6/10  = -0.65

-2.25 + 1 7/10  = -0.55

-2.25 + 1 8/10 = -0.45

-2.25 + 1 9/10 = -0.35

-2.25 + 1 8/9   = -0.361111111

-2.25 + 1 7/8   = -0.375

(-2.25) + 1 6/7 = -0.392857143

(-2.25) + 1 5/6 = -0.416666667

(-2.25) + 1 4/5 = -0.45

(-2.25) + 1 3/4 = -0.5

(-2.25) + 1 2/4 = -0.75   is the same as 1 5/10 = -2.25 + 1/2 = -0.75

(-2.25) + 1 2/3 = -0.583333333 - 0.47222222

(-2.25) + 1 7/9 =-0.472222222   1 7/9 is smaller number than 1 2/3 by 0.10555555

We know 1  7/9 it is smaller than 1 8/9 as  -2.25 + 1 8/9   = -0.361111111 but only by -0.111111112

as the difference of 1/9 = -0.111111112

etc etc.

Summary when adding additional 1/10 it adds 0.1

when adding additional 1/9 it adds 0.111111112

when adding additional 1/8 it adds 0.125

when adding additional 1/7 it adds 0.142857143

when adding additional 1/6 it adds 0.166666667

when adding additional 1/5 it adds 0.2

when adding additional 1/4 it adds 0.25

Answer:

10

Step-by-step explanation:

Since we are dealing with area, we need to multiply 16 1/4 by 11 3/4.

If we do that, we get 190 15/16

So, if we divide 190 15/16 by 20:

[tex]190 \frac{15}{16} / 20 = 9.5[/tex]

You cannot have half a bag however. You will need to round the number to 10.

Answer:

20

Step-by-step explanation:

In class 1, they used 10 sweet potatoes.

If they need 30, in class 2, they used 20.

The second class needs 0.4 sweet potatoes to make the remaining pies.

The percentage is defined as a ratio expressed as a fraction of 100.

If Ms. Knight's two cooking classes are making a total of 30 sweet potato pies and each pie requires 2% sweet potatoes, then the total amount of sweet potatoes needed is:

30 pies x 2% sweet potatoes per pie = 0.6 sweet potatoes

Her first class makes 1/3 of the total number of pies needed, which is:

1/3 x 30 pies = 10 pies

This means that the first class used:

10 pies x 2% sweet potatoes per pie = 0.2 sweet potatoes

So, the second class needs to make the remaining pies, which is:

30 pies - 10 pies = 20 pies

The second class needs to use:

20 pies x 2% sweet potatoes per pie = 0.4 sweet potatoes.

Therefore, the second class needs 0.4 sweet potatoes to make the remaining pies.

Answer:

opposite

Step-by-step explanation:

it's negative

Answer:

Step-by-step explanation:

Given,

Perimeter of fencing bought by Claire for rectangular garden

= 2(4x - 4 + x - 4)

= 2 ( 5x - 8 )

= 10x - 16

Perimeter of fencing bought by Claire for triangular garden

= (3x - 1) + (3x - 1) + 3x

= 3x + 3x + 3x - 1 - 1

= 9x - 2

Since,

The two gardens have same perimeter,

By the problem,

10x - 16 = 9x - 2

=> 10x - 9x = 16 - 2

=> x = 14

Hence,

Feet of fencing bought by her,

Putting value in any of the perimeters of the gardens,

10x - 16

= 10(14) - 16

= 140 - 16

= 124 feet (Ans)

Answer:

Step-by-step explanation:

Length, L = 2x + 2

Width, W = 3x

Height, H = 4x - 2

[tex]Surface\ Area = 2 (LW + WH + HL)\\\\[/tex]

                     [tex]= 2 ( (2x +2)(3x) + (3x)(4x -2) + (4x - 2)(2x + 2))\\\\=2(6x ^2 + 6x + 12x^2 - 6x + 8x^2 + 8x - 4x - 4)\\\\=2(26x^2 +4x -4) \ square \ units[/tex]

[tex]Volume = L \times W \times H[/tex]

           [tex]= (2x+2)(3x)(4x-2)\\\\=(6x^2 + 6x)(4x-2)\\\\=24x^3 -12x^2 + 24x^2 - 12x\\\\=24x^3 +12x^2 -12x \ cubic \ units[/tex]

Answer:

Answer is 6^9 ÷ 6^-2

Step-by-step explanation:

6^14 ÷ 6^2 = 6^14-2

= 6^12

And

6^9 ÷ 6^-2 = 6^9-(-2)

= 6^11

Which is less than 6^12

Answer:

205°

Step-by-step explanation:

The total circle is 360°. The right angle is 90°, and you know the other angle is 64°. 90° + 64° is 154°. 360° -154° is 205°.

Answer:

We know that the angle around any given point is 360°

Therefore, according to the given problem,

[tex]x° + 64° + 90° = 360° \\ x° + 154° = 360° \\ x° = 360° - 154° \\ \boxed{x° = 206°}[/tex]

Hence, the value of x° is 206°

Answer:

They lost 29.3% of the softball games.

Step-by-step explanation:

Total number of games = 75

Number of games won = 55

Number of games lost = 75 − 55 = 22

Percentage of games lost: Number of games lost/ total games x 100%

Which means: 22/75 x 100% = 29.3%

Answer:

-13, 8

Step-by-step explanation:

(x-3)(x+8) = 80

use FOIL to eliminate parenthesis

x² +8x - 3x - 24 = 80

combine like terms

x² + 5x - 24 = 80

move the constant to the left

x² + 5x - 104 = 0

factor x and then factor -8

x(x+13) - 8(x+13) = 0    factor (x+13)

(x+13)(x-8) = 0

separate into possible cases

x + 13 = 0

x - 8 = 0

solve

x = -13

x = 8

Answer: -x = 2.12 (approx.)

Step-by-step explanation:

x = -70/33 -- divide -70 by 33

x = -2.12

x/-1 = -2.12/-1 -- divide each side by -1

-x = 2.12

Using the principle of proportional relationship, the number of milk cups required per cup of oat is 0.75 cups

Setting up a proportional relationship between milk and oat :

1/2 cups = 2/3 cups

x cups = 1 cup

Cross multiply :

(2/3)x = 1/2

0.666666x = 0.5

Divide both sides by 0.66666 to isolate x

x = 0.5 / 0.666666

x = 0.75

Therefore, 0.75 cups of milk is required per cup of oat.

Answer:

sorry I don't no the answer

Step-by-step explanation:

sum of all angles of triangle are 180°

therefore,

angle,

P + T + S = 180°

P = 90° , T = 36° ( given )

so,

→ 90 + 36 + S = 180

→ 126 + S = 180

→ S = 180 - 126 = 54°

→ S = 54°

therefore, S is 54° so, option D is correct.
