Answer:

(x-6)^2 + (y+8)^2 = 25

Step-by-step explanation:

The equation for a circle can be written as

(x-h)^2 + (y- k)^2 = r^2

where (h,k) is the center and r is the radius

The diameter is 10 so the radius is 10/2 =5

the center is 6,-8

(x-6)^2 + (y- -8)^2 = 5^2

(x-6)^2 + (y+8)^2 = 5^2

(x-6)^2 + (y+8)^2 = 25

Answer:

(i) 30

(ii) 8

Step-by-step explanation:

Start by drawing 3 rings for the Venn diagram.  Each ring represents either Audi, BMW, or Citroën.

Next, add the information provided in the problem statement.  We know that 20 choose BMW only.  Another 20 choose Citroën only.

We know the number who choose all 3 is the same as the number that choose BMW and Citroën, but not Audi.  We'll call this number x.

Similarly, we know that the number who choose all 3 is half of those choose Audi and BMW, but not Citroën.  So we'll say that number is 2x.

We know the total number of Audi votes is 48, the total number of BMW votes is 36, and the total number of Citroën votes is 34.

Finally, we know the total number of voters is 100, including those who voted for no favorites (we'll call that number n).

We know that BMW got 36 votes, so:

20 + x + x + 2x = 36

20 + 4x = 36

4x = 16

x = 4

We know that Citroën got 34 votes, so:

20 + x + x + z = 34

20 + 4 + 4 + z = 34

28 + z = 34

z = 6

We know that Audi got 48 votes:

y + 2x + x + z = 48

y + 2(4) + 4 + 6 = 48

y + 18 = 48

y = 30

Finally, we know that the total number of voters is 100.

20 + 20 + x + x + 2x + y + z + n = 100

20 + 20 + 4 + 4 + 2(4) + 30 + 6 + n = 100

92 + n = 100

n = 8

Answer:

length: 12m

width: 2m

Step-by-step explanation:

24 = a*w

a = w+10

then:

24 = (w+10)w

24 = w*w + 10*w

24 = w² + 10w

0 = w² + 10 - 24

w = {-10±√((10²)-(4*1*-24))} / (2*1)

w = {-10±√(100+96)} / 2

w = {-10±√196} / 2

w = {-10±14} / 2

only positive numbers:

w = {-10+14}/2

w = 4/2

w = 2m

a = w+10

a = 2 + 10

a = 12m

Check:

24 = 12*2

Answer:

n = 19/5

Step-by-step explanation:

2(n - 5) represents "twice the difference of a number n and 5" and is equal to 9:

2(n - 5) = 9.

Performing the multiplication:

2n - 10 = 9, and so

2n = 19, or n = 19/5

Step-by-step explanation:

We can easily graph the equation if we know it’s y and x intercepts. We can plot these points on a coordinate plane then connect them using a ruler, then extend these further.

Mathematically, we can find the slope which is rise over run. Every time x increases by 5, y increases by 6. This means the slope is [tex]\frac{6}{5}[/tex]. We also know the y-intercept is -6, so the equation is [tex]y=\frac{6}{5}x - 6[/tex].

Answer:

zx - 100y = 0

Step-by-step explanation:

Since, x% of z is equal to y

[tex] \therefore \: \frac{x}{100} \times z = y \\ \therefore \: \frac{xz}{100} = y \\ \therefore \: zx = 100y \\ \therefore \: zx - 100y = 0[/tex]

The literal equation that represents x% of z is equal to y will be xz = 100y.

The quantity of anything is stated as though it were a fraction of a hundred. A quarter of 100 can be used to express the ratio. Per 100 is what the term percent signifies. The symbol ‘%’ is used to symbolize it.

x% of z is equal to y.

Then the literal equation that represents x% of z is equal to y will be given as,

x% of z = y

xz / 100 = y

xz = 100y

The literal equation that represents x% of z is equal to y will be xz = 100y.

Answer:

33°

Step-by-step explanation:

We were given that:

1- The angles of a triangle add up to 180 degrees

2- The second angle is 15 degrees larger than the smallest angle

3- The third angle is 3 times as big as the smallest angle

So, first of all, let's call the smallest angle x.

the second angle will be (x + 15°) since it is 15 degrees greater than the smallest angle

and the third will be 3x, since it is 3 times bigger than the smallest angle.

With the information we have, we can form an equation!

180° = x + (x+ 15°) + 3x

180° = 5x + 15°

180° - 15° = 5x + 15° - 15°

165° = 5x

165°/5 = 5x/5

33° = x

therefore, the smallest angle measures 33° degrees, the second angle measures 48° and the third angle measures 99°.

99° + 33° + 48° = 180°

so it is safe to say this answer is correct!

If the angles of a triangle add up to 180 degrees. The second angle is 15 degrees larger than the smallest angle. The third angle is 3 times as big as the smallest angle then 35 degree is the measure of the smallest angle.

The sum of three angles is 180 degrees

Let the smallest angle be x

The second angle is 15 degrees  larger than the smallest angle.

The third angle is 3 times as big as the smallest angle.

We need to find smallest angle.

The sum of three angles of a triangle is 180 degrees

Let the smallest angle be x

The second angle is 15 degrees  larger than the smallest angle.

The third angle is 3 times as big as the smallest angle.

We need to find smallest angle x=?

x+(x+15)+3x=180

2x+15+3x=180

5x+15=180

5x=165

Divide both sides by 5.

x=35

Therefore the smallest angle is 35 degree.

Answer:

x = 151

Step-by-step explanation:

In the figure given, x is an exterior angle of the ∆.

According to the exterior angle theorem, x = the sum of the two opposite interior angles of the ∆.

One of the opposite angles measures 101°, while the second opposite angle equal 50°, since line l is parallel to m, alternate interior angles are equal.

Therefore, x = 101 + 50 = 151°

Answer:

(0, - 23 )

Step-by-step explanation:

Find the equation of the line in slope- intercept form

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

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

with (x₁, y₁ ) = (- 72, 25) and (x₂, y₂ ) = (- 36, 1) ← 2 ordered pairs from the table

m = [tex]\frac{1-25}{-36+72}[/tex] = [tex]\frac{-24}{36}[/tex] = - [tex]\frac{2}{3}[/tex] , thus

y = - [tex]\frac{2}{3}[/tex] + c

To find c substitute any ordered pair into the equation

Using (- 54, 13 ) , then

13 = 36 + c ⇒ c = 13 - 36 = - 23 ← y- intercept

Thus coordinates of y- intercept = (0, - 23 )

Answer:

E

Step-by-step explanation:

Let's let c denote the amount of cashews and let's let p denote the amount of peanuts.

So, the owner wants to mix cashews worth $5.50 per pound with peanuts worth $2.30 per pound to get a 1/2 pound mixture that is worth $2.80 per pound.

In other words, the total pounds as an equation is:

[tex]c+p=0.5[/tex]

Also, the price would be:

[tex]5.5c+2.3p=(p+c)2.8[/tex]

Since we mixed the peanuts and cashews, our sum would be 2.8(p+c).

And we already determined that p+c is 0.5. Thus, substitute:

[tex]5.5c+2.3p=(0.5)(2.8)[/tex]

Simplify:

[tex]5.5c+2.3p=1.4[/tex]

Now, we can solve the system of equations. Isolate a variable from the very first equation:

[tex]c+p=0.5[/tex]

Subtract p from both sides:

[tex]c=0.5-p[/tex]

Now, substitute this into the equation earlier:

[tex]5.5c+2.3p=1.4\\5.5(0.5-p)+2.3p=1.4[/tex]

Distribute:

[tex]2.75-5.5p+2.3p=1.4[/tex]

Combine like terms:

[tex]2.75-3.2p=1.4[/tex]

Subtract both sides by 2.75:

[tex]-3.2p=-1.35[/tex]

Divide everything by -3.2:

[tex]p=0.412875[/tex]

Now, find c:

[tex]p+c=.5[/tex]

Substitute:

[tex]c+0.421875=.5[/tex]

Subtract:

[tex]c=0.078125[/tex]

Thus, the owner would need 0.08 pounds of cashews and 0.42 pounds of peanuts.

Answer: 42

Because, 55 + 72 = 127. After you should do 3 ÷ 127. The divisor (3) goes into the first digit of the dividend (1), 0 times. Therefore, put 0 on top. Then you should Multiply the divisor by the result in the previous step (3 × 0 = 0) and write that answer below the dividend. After that Subtract the result in the previous step from the first digit of the dividend (1 - 0 = 1) and write the answer below.  Move down the 2nd digit of the dividend in the below. The divisor (3) goes into the bottom number (12), 4 time(s). Therefore, put 4 on top... Subtract the result in the previous step from the number written above it. (12 - 12 = 0) and write the answer at the bottom. Move down the last digit of the dividend in the below. The divisor (3) goes into the bottom number (7), 2 time(s). Therefore put 2 on top, Multiply the divisor by the result in the previous step (3 x 2 = 6) and write the answer at the bottom... Subtract the result in the previous step from the number written above it. (7 - 6 = 1) and write the answer at the bottom.  The answer is the top number and the remainder is the bottom number.

Therefore, the answer to 127 divided by 3 calculated using Long Division is
