Answer: [tex]5.79\times 10^{7}\ \text{Hz}[/tex]
Step-by-step explanation:
Given
Speed of radar wave [tex]v=2\times10^{6}\ m/s[/tex]
the wavelength of radar wave [tex]\lambda =0.0345\ m[/tex]
We know, [tex]velocity=frequency\times wavelength[/tex]
[tex]frequency=\dfrac{\text{velocity}}{\text{wavelength}}[/tex]
[tex]frequency=\dfrac{2\times10^6}{3.45\times10^{-2}}[/tex]
[tex]frequency=5.797\times 10^{7}\ Hz[/tex]
what is the length of a small paper clip?
Answer: 1.375 inches
Step-by-step explanation:
3х + 16 = 24
What is the answer??
Answer:
x = 8/3
Step-by-step explanation:
3x + 16 = 24
3x = 24 - 16 (subtract 16 from both sides)
3x = 8
x = 8/3 (divide both sides by 3)
2. A flag is 30 inches wide by 48 inches long.
Find the length of the diagonal of the flag?
Answer:
1440
Step-by-step explanation:
You multiply 30 by 48, so when it says something like "64 inches by 17 inches" you will have to multiply. Hope i helped!

Solve the simultaneous equations
6x + 5y = 32
2x + 5y = 12
V =
y =
Answer: x = 5, y = 2/5
Step-by-step explanation:
We have the system of equations:
6*x + 5*y = 32
2*x + 5*y = 12
To solve it, we can start by isolating one of the variables in one of the equations.
Because in both of them we have the term 5*y, i will isolate 5*y in the second equation:
5*y = 12 - 2*x
Now let's replace it in the first equation:
6*x + (12 - 2*x) = 32
Now let's solve it for x
6*x + 12 - 2*x = 32
(6*x - 2*x) = 32 - 12 = 20
4*x = 20
x = 20/4 = 5
Now we know the value of x, we can replace it in the equation:
5*y = 12 - 2*x
to find the value of y.
5*y = 12 - 2*5
5*y = 2
y = 2/5
Then the solution of the system is x = 5, y = 2/5

Write equations for the vertical and horizontal lines passing through the point (8, -1).
Answer:
x = 8 and y = - 1
Step-by-step explanation:
The equation of a vertical line parallel to the y- axis is
x = c
where c is the value of the x- coordinates the line passes through
The line passes through (8, - 1 ) with x- coordinate 8, then
x = 8 ← equation of vertical line
The equation of a horizontal line parallel to the x- axis is
y = c
where c is the value of the y- coordinates the line passes through
The line passes through (8, - 1 ) with y- coordinate - 1, then
y = - 1 ← equation of horizontal line
I need to know the answer please help me
Answer:
F: 12r+y
Step-by-step explanation:
- Why not G because if you multiple 2 by 6 and you get 12 then why not multiple the 6 too.
- Why not H because how do you get 16???
- Why not J because you don't add 2 pulse 6 to make 8 when you are supposes to multiple.
Hope this helps and sorry if wrong :)

7x + 4y = -3
-7x - 5y = 9
How do I solve using elimination
Answer:
X=3, y=-6
Step-by-step explanation:
7x+4y=-3 equation 1
-7x-5y=9 equation 2
-y=6. Add above two equations
Y=-6
solve for x by inputting y value into either equation.
7x+4(-6)=-3
7x-24=-3
7x=21
x=3
check answer by inputting x and y values into either equation
-7x-5y=9
-7(3)-5(-6)=9
–21+30=9
9=9
Richard and Teo have a combined age of 37. Richard is 13 years older than twice Teo's age. How old are Richard and Teo?
Answer:
Teo is 8 years old and Richard is 29 years old
Step-by-step explanation:
Let us solve the question
Assume that Teo is x years old
∵ Teo is x years old
∵ Richard is 13 years older than twice Teo's age
→ It means multiply x by 2, then add 13 to get the age of Richard
∴ Richard's age = 2x + 13
∵ Richard and Teo have a combined age of 37 years
→ Add their ages and equate the sum by 37
∴ x + 2x + 13 = 37
→ Add the like terms
∵ (x + 2x) + 13 = 37
∴ 3x + 13 = 37
→ Subtract 13 from both sides
∵ 3x + 13 - 13 = 37 - 13
∴ 3x = 24
→ Divide both sides by 3 to find x
∴ x = 8
∵ x represents Teo's age
∴ Teo is 8 years old
→ Substitute the value of x in the expression of Richard age to find his age
∵ Richard age = 2(8) + 13 = 16 + 13 = 29
∴ Richard is 29 years old
∴ Teo is 8 years old and Richard is 29 years old

Answer: Answer choice B
Pumped up gym has a membership plan that charges $35 a month plus a one time initiation fee of $20. If Jeremy has spent $545 on his membership, how long has he been a member?
Answer:
15 months
Step-by-step explanation:
35x+20=545
Subtract 20 from both side to figure out how many months he paid for....
35x+20-20=545-20
35x=525
Divide 35 on both sides....
x=15
Therefore, he has been a member for 15 months
Check:
35(15)+20=545
525+20=545
545=545
IT'S CORRECT!!!

You currently have a debt of $35. You earn and save $12 per week from your allowance. How
long will it take you to save $85?
Answer:
10 weeks
Step-by-step explanation:
12 * 3 = $36 At this point of 3 weeks you will be out of debt.
$12 * 7 weeks = $84 At this point you will be a dollar short, but you had a dollar left over after 3 weeks. This would put you at a total of $85.
So, it would take 3 weeks to get out of debt and 7 to get up to $85.
3 + 7 = 10
A= 10 weeks

8. What is the SLOPE of this line? *
1/2
5x+3y = 45
Answer:
The slope of given line is -5/3
Step-by-step explanation:
Given equation of line is:
5x+3y = 45
In order to find the slope of the given line, we have to convert the equation in slope-intercept form first
So,
[tex]5x+3y = 45\\3y = -5x+45[/tex]
Dividing both sides by 3
[tex]\frac{3y}{3} = \frac{-5}{3}x+\frac{45}{3}\\y = -\frac{5}{3}x+15[/tex]
The slope-intercept form is given by:
[tex]y = mx+b[/tex]
Here m(co-efficient of x) is the slope of line
Comparing both equations, we get
m = -5/3
Hence,
The slope of given line is -5/3

Answer:
Step-by-step explanation:x<-5/2
Finish the chart for
y= 1/2x
Answer:
So we know that y=1/2x. So we apply this equation on each x.
x=-2, so y=1/2*-2 which is -1. so y = -1
x=0, so y = 1/2 * 0 which is 0. so y=0
x=2, so y = 1/2*2 which is 1. so y=1
Hope this helps :))

The cat is 12 feet above the ground and the ladder is 9 feet away from the tree because of the mud. How long does the ladder needs to be to reach the tree
Answer:
15 feet
Step-by-step explanation:
The ladder is the hypotenuse of a right triangle, with the legs being 9 ft and 12 ft long (see the picture).
To solve for the length of the ladder, use the Pythagorean Theorem.
[tex]9^{2} +12^{2} =c^{2} \\c=\sqrt{9^{2} +12^{2}} \\c=\sqrt{81+144} \\c=\sqrt{225} \\c=15[/tex]

In a GP, there is a common ratio between the terms.
8 / (-16/5) = 8 * (-5/16) = -2.5
-20 / 8 = -2.5
We can see that every new term is -2.5 times bigger than the previous term.
Hence to find the next term,
we multiply -20 by -2.5:
(-20)(-2.5) = 50.
Hence 50 should go into the box.
Answer:
50
