25 POINTS. Radar used microwaved yo check the speed of cars. If a speed of the microwaves is 2 000 000 m/ s and the wavelength is 0.0345m calculate the frequency.

Answer:

11

Step-by-step explanation:

let the first number be n , then the second number is 5n and

the third number is 5n - 14

Sum the numbers and equate to 41

n + 5n + 5n - 14 = 41

11n - 14 = 41 ( add 14 to both sides )

11n = 55 ( divide both sides by 11 )

n = 5

Thus

first number = 5

second number = 5n = 5 × 5 = 25

third number = 5n - 14 = 5(5) - 14 = 25 - 14 = 11

Answer:

[tex]y+2=5(x+2)[/tex]

Step-by-step explanation:

Slope is negative reciprocal when lines are perpendicular to each other

therefore m=5

Equation of line in point slope form is given as

[tex]y-y_1=m(x-x_1)[/tex]

[tex]y+2=5(x+2)[/tex]

Answer:

x=95 degrees

Step-by-step explanation:

Explanation is: Opposite interior angles are congruent. So X= 95

Answer:

6 laps

Step-by-step explanation:

According to the scenario, calculation of the data are as follows:

Each lap = 0.25 miles

Regan's plan to run= 1.5 miles

So, we can calculate number of laps by using following formula,

Number of laps = Total miles to run ÷ each lap miles

By putting the value, we get

Number of laps = 1.5 miles ÷ 0.25 miles

= 6 laps

So, she should run 6 laps.

The slope of the graph of machine 1 is: 1/2

The slope of the graph of machine 2 is: 4/5

Step-by-step explanation:

Machine 1

Machine 1 Table is given by

Time (sec)             1         2         3         4

Amount (gal)         0.5      1        1.5       2

Taking two points

Determining the slope between any two points (1, 0.5) and (2, 1)

[tex]\left(x_1,\:y_1\right)=\left(1,\:0.5\right),\:\left(x_2,\:y_2\right)=\left(2,\:1\right)[/tex]

[tex]m=\frac{1-0.5}{2-1}[/tex]

[tex]m=0.5[/tex]

[tex]m = 1/2[/tex]

Therefore, the slope of the graph of machine 1 is: 1/2

Machine 2

Taking two points from the graph of Machine 2

Determining the between any two points (0, 0) and (10, 8)

[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\left(x_1,\:y_1\right)=\left(0,\:0\right),\:\left(x_2,\:y_2\right)=\left(10,\:8\right)[/tex]

[tex]m=\frac{8-0}{10-0}[/tex]

[tex]m=\frac{4}{5}[/tex]

Therefore, the slope of the graph of machine 2 is: 4/5

5. (1296)

6. (25)

7. (4.305)

8. (120)

9. (529)

10. ($2.59)

Step-by-step explanation: For 1 I just used a calculator, for 2 it is just going to be 12-9 which is 3, for 3 it is 5/2 x 7/3, make the denominators the same getting 15/6 x 14/6 and getting 210, now divide by 6 getting 35, for 4, it is -3-10 which is -13, for 5 do 6x6x6x6 which equals 1296,  for 6 do 48-23 = 25, for 7 just divide, I used a calculator, for 8, multiply 20 by 12 and get 240, now divide by 2 which is 120. for 9 do 23x23 which is 529, for 10, divide 12.59 by 5 and get an answer of 2.59.    HOPE THIS HELPED!

(4x²y³)² 8 x⁴y⁵ 8 x⁴ y⁶ 16  x⁴ y ⁵ 16 x⁴ y⁶  = 262,144 x²⁰ y²⁸

Step-by-step explanation:

Given

          (4x²y³)² 8 x⁴y⁵ 8 x⁴ y⁶ 16  x⁴ y ⁵ 16 x⁴ y⁶  

we know that

     [tex]a^{m} X a^{n} = a^{m+n}[/tex]

     [tex](a^{m} )^{n} = a^{mn}[/tex]

   =  (16x⁴y⁶ 8 x⁴y⁵ 8 x⁴ y⁶ 16  x⁴ y ⁵ 16 x⁴ y⁶  

   = 16 ×8×8×16×16 x⁴⁺⁴⁺⁴⁺⁴⁺⁴ y⁵⁺⁶⁺⁵⁺⁶⁺⁶

 = 262,144 x²⁰ y²⁸

She gave 20% away

Step-by-step explanation:

question 9

a) 2 x 3 = 6m^2

b) diameter = 2m and radius = 1m

c) πr^2 is the equation, so 3.14 x 1^2 = 3.14m^2

and the semi circle is half of that, 1.57m^2

d) 6 + 1.57 = 7.57m^7

question 10

30 x 70 = 2,100m^2

πr^2 so 3.14 x 15^2 = 706.5m^2

2,100 + 706.5 = 2,806.5m^2

i hope this is correct :D

39% as a fraction in its lowest form is 39/100.

To express 39% as a fraction in its lowest form, we need to divide the percentage by 100 and simplify the resulting fraction.

The percentage symbol "%" means "per hundred," so 39% can be written as 39/100.

To simplify this fraction, we can divide both the numerator and denominator by their greatest common divisor (GCD).

Here, the GCD of 39 and 100 is 1, so we divide both numbers by 1:

= 39 ÷ 1 / 100 ÷ 1

= 39/100

Therefore, 39% as a fraction in its lowest form is 39/100.

The perimeter of a rectangle is:

Step-by-step explanation:

Given

The width of a rectangle w =  8n - 8.5 feet

The length of a rectangle l = 8.5n + 10 feet

To determine

The perimeter of a rectangle = P = ?

The perimeter of a rectangle can be determined using the formula

[tex]P = 2(l+w)[/tex]

substitute l = 8.5n + 10 and w = 8n - 8.5

[tex]P=2\left(8.5n+10+8n-8.5\right)[/tex]

   [tex]=2\left(16.5n+10-8.5\right)[/tex]

   [tex]=2\left(16.5n+1.5\right)[/tex]
