the side length of the following right isosceles triangle is 10 cm. if the area of a equals the area of b, then what is the area of the circle which the sector aef is in?

Answer:

Thus, the number of sides: n ≈ 13  (rounded to the nearest whole number).

Step-by-step explanation:

We know that the formula of the sum of the measures of the interior  angles of a polygon

Sum = (n-2) × 180°

where

n is the number of sides

In your case, since the sum of the interior angles is 1930°, then

1930° = (n-2) × 180°

so we can determine the number of sides n, such as

1930 / 180 = n-2

[1930 / 180] + 2 = n

n ≈ 12.7

If 12.7 rounded to the nearest whole number, then

n ≈ 13

Thus, the number of sides: n ≈ 13 (rounded to the nearest whole number).

Answer:

1.5625

Step-by-step explanation:

Find the ratio (r) between adjacent members: 50,25,12.5,6.25,3.125

a_2/a_1=25/50=0.5

a_3/a_2=12.5/25=0.5

a_4/a_3=6.25/12.5=0.5

a_5/a_4=3.125/6.25=0.5

The ration (r) between every two adjacent members of the series is constant and equal to 0.5 thus:

a_6 =a_1×(^r6-1)  =a_1×r^5 =50×0.5^5 =1.5625

Answer:

He spent 20,000 points on the castle and 12,000 points on the spell.

Step-by-step explanation:

It says that he spent 5/8 points on the castle

32000/1 x 5/8 = 20,000

We got our points for the castle. Now we need to find how many points for the spells, which is the remaining. 32000-20,000=12,000

This means that 20,000 points are used on the castle and 12,000 on the spell.

Answer:20000 and 12000

Answer:

4 oil changes

Step-by-step explanation:

Given that:

Distance after first oil change = 5000 miles

Subsequent oil changes = 3300 miles

If distance in miles moved per week = 250 m

Number of weeks per year = 52

Total miles moved per year = (250 * 52) = 13000 miles

Let Number of oil change per year = n

Difference between successive oil change = d = 3300 miles

Using the relation :

Total miles = Ist change + (n - 1)d

13000 = 5000 + (n - 1)3300

13000 = 5000 + 3300n - 3300

13000 = 1700 + 3300n

13000 - 1700 = 3300n

11300 = 3300n

n = 3.424

Hence, number of oil. Changes in first year = 4

Answer:

1/250

Step-by-step explanation:

0.4% = 0.004 =  [tex]\frac{4}{1000}[/tex]

divide numerator and denominator of [tex]\frac{4}{1000}[/tex] by 4 to get [tex]\frac{1}{250}[/tex]

Answer:

  x = 30

Step-by-step explanation:

Supplementary angles total 180°.

  5x° +x° = 180°

  6x = 180

  x = 180/6 = 30

The value of x is 30.

Answer:

(-20)

Step-by-step explanation:

-4 - 2(4 + (-2) )³ = -4 - 2(4 - 2)³

                        = -4 - 2*(2)³

                       = -4 - 2* 8

                      = -4 - 16

                     = -20

Answer: y = 2x + 2

Answer:

[tex]x=\sqrt{12}[/tex]

Step-by-step explanation:

The Pythagorean theorem states that [tex]a^2+b^2=c^2[/tex] in a right triangle where c is the longest side. To solve for x, we plug in the side lengths given as a and c.

[tex]a^2+b^2=c^2\\2^2+x^2=4^2[/tex]

Move 2² to the other side to isolate b²

[tex]x^2=4^2-2^2[/tex]

Square root both sides to isolate b

[tex]x=\sqrt{4^2-2^2}\\x=\sqrt{16-4} \\x=\sqrt{12}[/tex]

Answer:

70

Step-by-step explanation:

Answer:

C. The relationship between the quantities is: add 25.

Step-by-step explanation:

1x = 25y,

2x = 25 + 25 = 50y

3x = 50 + 25 = 75y

4x = 75 + 25 = 100y

Note:

As you can see, every time the number goes up on the chart, it goes up by 25 and you can find that out by just simply adding 25 to the first number and seeing if it matches up with the next, (which I did above).

Answer:

y = 3x - 5

Step-by-step explanation:

Point-slope form: y - y₁ = m(x - x₁)

Substitute the values for the variables.

y - 7 = 3(x - 4)

y - 7 = 3x - 12

y = 3x - 5

Answer:

The answer to the question is

25 % increase in production rate

Step-by-step explanation:

To solve the question, we note that

Initial number of products = 84 toy robots per day

Present production rate = 105 robots per day

The percentage increase is given by the increase in production rate divided by the original production rate multiplied by 100  

Where increase in production rate = 105 - 84 = 21

Percentage increase = 21/84 ×100 = 25 % increase
