The endpoints of the diameter of a circle have the coordinates (3,8) and (9,16) .
What are the coordinates of the center of the circle?

Answer:

So x changes by 10 and the you do 25-6.25

then y/x =1.875x

Answer:

$69.51

Step-by-step explanation:

To solve the discount problem we have to multiply the price by the new percent (trust me it will make sense later)

To find the new percent after the 30% discount we have to subtract 30% from 100% which will leave us with 70% or 0.70

Now we multiply:

$99.30 x 0.70 = 69.51

So the new price after the discount is $69.51

Step-by-step explanation:

Answer:

b = 4y

y = 1/4 * b

Step-by-step explanation:

Number of Blue fish = 16

Number of yellow fish = 4

Let:

Blue fish = b

Yellow fish = y

b = 4y

b = 4(4)

b = 16

From ;

b =4y

y = b/4

y = 1/4 * b

Hence,

y = 1/4 * 16

y = 16/4

y = 4

Answer:

s=  -5

Step-by-step explanation:

have a good day

Answer:

Step-by-step explanation:

subtract 28 on both sides that will cancel the 28

-35 = 7s, divide both sides by 7, this cancels the 7

- 5 = s

s=-5

Answer:

17.5

Step-by-step explanation:

let 'x' = each congruent side

let '2x - 7' = side of base

x + 2x - 7 = 63

3x = 70

x = 17.5

Answer:

The star equals 96

Step-by-step explanation:

The star will be equal to 5x-14 because they are vertically opposite.

The two exterior angles are supplementary.  Set up the equation

5x - 14 + 3x + 18 = 180        Combine the terms on the left.

8x + 4 = 180                        Subtract 4 from both sides

8x = 180 - 4                         Combine

8x = 176                               Divide by 8

x = 176 / 8

x = 22

===================

5x - 14

5*22 - 14

96

Step-by-step explanation:

2t - 30([tex]\frac{1}{5}[/tex]) = 20

2t - [tex]\frac{30}{1}[/tex] ([tex]\frac{1}{5}[/tex]) = 20

2t - [tex]\frac{30}{5}[/tex] = 20

2t - 6 = 20

2t - 6 + 6 = 20 +6

2t = 26

[tex]\frac{2t}{2}[/tex] = [tex]\frac{26}{2}[/tex]

t = 13

Answer:

v = 4

Step-by-step explanation:

u + at = v

a (-2) multiplied by t (3) = -6

-6 + u (10) = 4

Answer:

[tex]v=4[/tex]

Step-by-step explanation:

[tex]v=u+at[/tex]

Substitute u=10, a=-2 and t=3 in above equation

[tex]v=10-2(3)[/tex]

[tex]v=4[/tex]

Answer:

slope=-1/2

Step-by-step explanation:

Answer:

-1/2

Step-by-step explanation:

Since it goes up 1 the numerator would be 1 and since it goes to the left 2 the denominator would be -2. the fraction would be -1/2.

Answer:

y = -x + 1

Step-by-step explanation:

We're putting it into the form y=mx+b where m is the slope, and b is the y-intercept.

When two lines are parallel, they have the same slope, so the slope is going to be -1.

New equation: y = -x + b.

Now, you know that (4, -3) is a solution so you can plug in x = 4 and y = -3, then see what value of b make the equation true.

-3 = -4 + b

add 4 to both sides

1 = b

This means that the equation is y = -x + 1

Answer:

Your answer is 31.4°.

Step-by-step explanation:

The answer itself just requires very simple thinking. Complementary angles are any two angles that add up to 90 degrees. We are given ANGLE<1, so all we have to do is subtract 90 from 58.6 to find ANGLE<2.

90°-58.6°= 31.4°

Answer:

Frequency of wave = 3 Hertz

Step-by-step explanation:

Given that:

Wavelength of wave = 20 meters

Velocity of wave = 60m/s

We know that:

v = fλ

Here,

v = velocity , f = frequency and λ = wavelength

Putting values in formula

60 = f(20)

20f = 60

Dividing both sides by 20

[tex]\frac{20f}{20}=\frac{60}{20}[/tex]

f = 3 Hertz

Hence,

Frequency of wave = 3 Hertz
