Step-by-step explanation:

Have a nice day

Answer:

74.948

Step-by-step explanation:

To decrease a number by a percentage, we can simply multiply the number by the reciprocal of the decrease.

To decrease 82 by 8.6 % , we can simply multiply 82 by 91.4%……..

82 x .914= 74.948

Rounded to nearest tenth……..74.9

Answer:

We are dividing a slab of wood into equal pieces, so the obvious function would be to divide. And how long are the pieces going to be? 1/4 of a foot. so that gives us:

6 ÷ ¼.

Now, when we divide by a fraction, we flip the numerator and denominator and multiply, so the equation will look like:

6 * 4

Solve that, and you'll have your answer.

Step-by-step explanation:

Hope this answer helps you :)

Have a great day

24) IN A PARALLELOGRAM OPPOSITE ANGLES ARE EQUAL

3y + 2 = 62

3y = 62 - 2

3y = 60

y = 60/3

y = 20°

ALSO IN A PARALLELOGRAM ADJACENT SIDES SUM IS 180°

62 + 5x + 3 = 180°

5x + 65 = 180

5x = 180 - 65

5x = 115

x = 115/5

x = 23°

so option c is correct

25) IN A PARALLELOGRAM THE SIDES OF SAME DIAGONAL ARE EQUAL

x = 4

4x + 14 = 3y + 9

4(4) + 14 = 3y + 9

16 + 14 = 3y + 9

30 = 3y + 9

3y = 30 - 9

3y = 21

y = 21/3

y = 7

Answer:

Complementary angles sum to 90°.

∠X has ∠P complementary to it as:

Answer:

x = 6.8829

Step-by-step explanation:

[tex]\frac{sin\left(35\right)}{x}=\frac{sin\left(90\right)}{12}[/tex]

Answer:

x ≈ 6.8

Step-by-step explanation:

Label each side of the triangle with "a" (adjacent), "o" (opposite), or "h" (hypotenuse).

Side x is the opposite, side 12 is the hypotenuse, and the other side is the adjacent.

Use SOH-CAH-TOA to find the missing side (Sin, Cos, Tan).

To find x, we need to use SOH or Sin(a)= O/H

Plug in the adjacent angle for a and 12 for h then solve:

Sin(35)=O/12

The calculator approximation of Sin(35) is 0.5735.

0.5735  ≈ O/12

Multiply both sides by 12:

12 * 0.5735  ≈ O/12 * 12

O ≈ 6.882

Round to nearest tenth:

O ≈ 6.8

Answer:

7

Step-by-step explanation:

a=2

b=2

c=1

2ab cos C=a²+b²-c²=2²+2²-1²=4+4-1=7

Answer:

C

Step-by-step explanation:

Given

a² + b² - 2abcosC = c² ( subtract c² from both sides )

a² + b² - c² - 2abcosC = 0 ( add 2abcosC to both sides )

a² + b² - c² = 2abcosC

Here a = 2, b = 2, c = 1 , then

2² + 2² - 1² = 2abcosC

4 + 4 - 1 = 2abcosC , then

2abcosC = 7 → C

Answer:

Step-by-step explanation:

Area of the quarter circle = 1/4 pi * r^2

Area of the quarter circle = 1/4 * 3.14 * r^2

Area of the triangle = 1/2 r * r = 1/2 r^2

Equation of Solution

1/4 3.14 * r^2 = 14 cm^2 + 1/2 * r^2                    Subtract 1/2 r^2 from both sides

0.785 r^2 - 0.5 r^2 = 14 cm^2                           Combine the left

0.285 r^2  = 14. cm^2                                        Divide by 0.285

r^2 = 14/0.285

r^2 = 49.1228                                                     Take the square root of both sides

sqrt(r^2) = sqrt(49.1228)

r = 7.01

Answer:

The formula is 4cm times 9cm which is 36cm. Then times that by pi which is 113.04. The answer is 113.04

Step-by-step explanation:

Answer:

Volume - 452.16 cm

Step-by-step explanation:

First we need to find the area of the circle.

Area of a circle - (3.14)r^2

Insert the radius in the formula -

(3.14) (4)^2

3.14 x 16

50.24 is the area of the circle

Now, we have to multiply this value by the height of the cylinder in order to find the volume.

50.24 x 9 = 452.16 cm

Step-by-step explanation:

The region with the competition for resources is region C with the highest population density

The population density, or the number of people divided by the area's size, is determined by the number of people who reside there. Numerous creatures' distribution, growth, and migration can all be explained by population density.

Population density = number of people / the area they occupy

Given data ,

Let the population density be represented as P

Region    Population    Area

A               1,312       212

B               630         314

C               16,400     625

D               17,800      902

Now , the state with the highest population density will have the greater competition for the resources

So , The population density in Region A = 1312 / 212 = 6.19

The population density in Region B = 630 / 314 = 2

The population density in Region C = 16400 / 625 = 26.24

The population density in Region D = 17800 / 902 = 19.7

Hence , the region C has the highest population density

Answer:

36

Step-by-step explanation:

f * √g = k

12 * √64 = k

k = ± 96

g = k² / f² = (± 96)² / 16² = 36

Answer:

g = 36

Step-by-step explanation:

Given f is inversely proportional to [tex]\sqrt{g}[/tex] then the equation relating them is

f = [tex]\frac{k}{\sqrt{g} }[/tex] ← k is the constant of proportion

To find k use the condition when f = 12 , g = 64 , then

12 = [tex]\frac{k}{\sqrt{64} }[/tex] = [tex]\frac{k}{8}[/tex] ( multiply both sides by 8 )

96 = k

f = [tex]\frac{96}{\sqrt{g} }[/tex] ← equation of proportion

When f = 16 , then

16 = [tex]\frac{96}{\sqrt{g} }[/tex] ( multiply both sides by [tex]\sqrt{g}[/tex]

16 × [tex]\sqrt{g}[/tex] = 96 ( divide both sides by 16 )

[tex]\sqrt{g}[/tex] = 6 ( square both sides )

g = 6² = 36

Step-by-step explanation:

[tex] \tan( \frac{7\pi}{6} ) \\ = \tan( \pi + \frac{\pi}{ 6} ) \\ = \tan( \frac{\pi}{6} ) [/tex]

as this angle lies in the third quadrant and tan x is positive in the third quad.

[tex] = \frac{1}{ \sqrt{3} } \\ as \: the \: value \: of \: \tan( \frac{\pi}{6} ) = \frac{1}{ \sqrt{3} } \\

Answer:

2x² + 9x - 5 = 0

b = 9

Step-by-step explanation:

(2x - 1) (x + 5) = 0

Expand

2x² + 10x - x - 5 = 0

Simplify

2x² + 9x - 5 = 0

b = 9

Step-by-step explanation:

in a parallelogram, opposite angles are equal..

so C is 4a + 22. and B is 6a - 12.

sum of interior angles in a quadrilateral = 360

4a + 22. + 6a - 12. + 4a + 22. + 6a - 12 = 360

20a + 20 = 360

20a = 340

a = 17

sum of angles on a straight line = 180

B + x = 180

6 ( 17) - 12 + x = 180

102 + × = 180

× = 180 - 102

× = 78

Answer and Step-by-step explanation:

We are given a linear pair. The angles of a linear pair add up to 180.

To find x, add the two angles together and equal it to 180, then solve for x.

126 + x + 23 = 180

Simplify.

149 + x = 180

Subtract both sides of the equation by 149.

x = 31

x = 31 is the answer.
