solution to 8n is less than72

Answer:

measure of angle C = 18°

c = 2.47

a = 7.61

Step-by-step explanation:

Make sure your calculator is in degree mode.

Angle A measures 72°, so angle C measures 18° (Angles A and C are complementary angles, so their sum is 90°).

[tex] \sin(18) = \frac{c}{8} [/tex]

[tex]c = 8 \sin(18) = 2.47[/tex]

[tex]a = 8 \cos(18) = 7.61[/tex]

Answer:

16

Step-by-step explanation:

x^2 -8x=0

rewrite in this form and add 16 to both sides:

x² + 2(- 4)x + 16 = 0 + 16

(x - 4)² = 16 ( take square root of both sides )

x - 4 = ±  4

x =  4 ± 4

x=8 , x= 0

Answer:

80 degrees

Step-by-step explanation:

Answer:

84 inches

Step-by-step explanation:

It is the perimeter.

Koda needs 84 inches of ribbon to put it around the edge of the board.

A classroom board is 24 inches wide and 18 inches tall, Koda s putting ribbon along the outside edge of the board.

Perimeter is the measure of the figure on its circumference.

Here,
length = 24 inch
width = 18 inch
The perimeter of the board, = 2 {length  + width]
                                             = 2 [24 + 18]

                                             = 84

Thus, Koda needs 84 inches of ribbon to put it around the edge of the board.

it's a that's the answer

Answer:

Heavenly,  we need the forumula for the area of a triangle, do you know it?

Step-by-step explanation:

Area of a triangle is (1/2 ) * B*H

where B = base

H = height

then

A = 1/2* B * H

A is given to be 20

B = b

H = b+4

plug all those into the formula,

20 = (1/2)*b*(b+4)

use your algebra skillz  :P

20 = 1/2 *( [tex]b^{2}[/tex] + 4b)

20*2 = [tex]b^{2}[/tex] + 4b

40 = [tex]b^{2}[/tex] + 4b

0 = [tex]b^{2}[/tex] + 4b-40

rewrite the above so it's in x format

[tex]x^{2}[/tex] + 4x -40 = 0

use the quadratic formula to find  x  , and for our problem, remember that x represents the base,  or b,  but don't mix it up with the b in the quadatic fomula,  with the b of the triangle, which is the base,  they are differnt "b"s   :P

X = (b±[tex]\sqrt{b^{2}-4*a*c }[/tex] ) / 2*a

a = 1

b = 4

c = -40

x = (4±[tex]\sqrt{4^{2}-4*1*(-40) }[/tex]  ) /2*1

x = ( 4±[tex]\sqrt{16+160}[/tex] ) / 2

x = (4±[tex]\sqrt{176}[/tex] ) / 2

x = (4±13.266499)/2

x= 2±6.633249

x = 2 + 6.633249 = 8.633

b= 8.633 cm

To find :-

The angle ∠ABC = ?

Given :-

∠BCD = 65°

∠BDC = 30°

Solution :-

Firstly we have to find ∠CBD, with the help of ∠CBD, we will able to find ∠ABC.

To find ∠CBD, we will use angle sum formula

(=> The sum of angles of all 3 sides of triangle is equal to 180°).

∠CBD + ∠BCD + ∠BDC = 180° (angle sum property)

∠CBD + 65° + 30° = 180°

∠CBD + 95° = 180°

∠CBD = 180° - 95°

∠CBD = 85°

Now we have ∠CBD, and in the diagram ∠CBD and ∠ABD lies on the same line but it is seperated by line BC, it means they are linear pair and the sum of both angles (∠CBD and ∠ABC) is equal to 180°.

∠ABC + ∠CBD = 180° (linear pair)

∠ABC + 85° = 180°

∠ABC = 180° - 85°

∠ABC = 95°

Result :-

The ∠ABC is 95° by using the above method.

Choose the first option

(A) 95°

Step-by-step explanation:

Square objects have four sides of equal length

so the perimeter of the drawing will be   4 * 2.5 = 10 inches

  area of drawing = 2.5 x 2.5 = 6.25 in^2

the actual object will have side lengths

       2.5 in  / 1 inch/ 5mm = 12.5 mm

   four sides each 12. 5 mm = 50 mm

      area of object = 12.5 x 12.5 = 156.25 mm^2

Step-by-step explanation:

The annual premium result in an annual out-of-pocket expense that is about the same as her current plan is $0.28 per $100 of value.

Insurance premiums are paid for policies that cover all the basic needs such as healthcare, home, and life insurance.

We are given Amount of insurance policy for Stephanie = $ 355,000

Annual premium = $ 0.42 per $100

Deductible amount = $ 500

Total Annual out of pocket expense

= [($355,000/100) x $0.42] + $500

= $1,991  

Now, the New Deductible amount that Stephanie wants is $ 1000

So, Let the annual premium be x

To find the annual premium in an annual out-of-pocket expense that is about the same as her current plan when the deductible amount increases to $1000

355,000x / 100 + 1000 = 1991

3550x + 1000 = 1991

3550x = 1991 - 1000

3550x = 991

x = 991/3550

x = 0.279≈0.28

Hence the annual premium result in an annual out-of-pocket expense that is about the same as her current plan is $0.28 per $100 of value.

Find the average growth per year of the populations of rabbits farm A

Over the first 2 years

for t=0

numbers of rabbits=5 (is not exact)

for t=2

numbers of rabbits=40

average=[40-5]/2---------> 17.5

step 2

Find the average growth per year of the populations of rabbits farm B

Over the first 2 years

for t=0

numbers of rabbits=5 (is not exact)

for t=2

numbers of rabbits=30

average=[30-5]/2---------> 12.5

step 3

Compare the average growth per year of the populations of rabbits on both farms

farm A=17.5

farm B=12.5

the average rate of population growth of rabbits in farm A is greater than average rate of population growth of rabbits in farm B by about 5 rabbits per year.

therefore

the answer is the option C)

the average rate of population growth of rabbits in farm A is greater than average rate of population growth of rabbits in farm B by about 6 rabbits per year.

The value of x is equal to 30.

Step-by-step explanation:

Let's define what are 2 equations are:

Since we are dealing with a straight line, the line's angle will always equal 180°.

Since the 2 angles must add up to 180°, then they must be supplementary angles.

We can set up our equation to solve for x:

This equation states that the 2 angles, given in formulas, must be equal to the angle of the line.

We can now solve this equation and get a value of x:

∴ we have found the value of x to be equal to 30.

1/32

Step-by-step explanation:

We can break this question down. If we had 1 person and they are right-handed, the probability is 1/2 because they are either left-handed or right-handed. Knowing that, we can multiply the probability of having 1 person being right-handed 5 times because there are 5 people in the question.

1/2 × 1/2 × 1/2 × 1/2 × 1/2 = 1/(2⁵) = 1/32

Therefore, the probability of randomly selecting 5 people who are right-handed is 1/32.
