Points B, D, E and F lie on a circle.
ABC is the tangent to the circle at B.
Find the size of angle ABD.
You must give a reason for each stage of your working.

Step-by-step explanation:

m∠A = 70°

m∠B = 30°

m∠C = 80°

Sum of all three angles = 70° + 30° + 80° = 180°

Answer:

U h m 17/12- 49/40= 23/120 so i.d.k what to say-

Step-by-step explanation:

Answer:

1/6 or C

Step-by-step explanation:

If you do 17/12 minus 49/40 you will get 23/120.

The question says which choice has a value that is closest to the answer of the expression.

Because of this you could/would round 23 to 20 which is making it 20/120.

If you simplify 20/120 you get 1/6.

Thus, making your answer 1/6.

I hope this helped and have a good day! :)

Answer:

(-4,10)

Step-by-step explanation:

The coordinate point of point B (x₁, y₁) will be (−4, 10). Then the correct option is D.

Coordinate geometry is the study of geometry using the points in space. Using this, it is possible to find the distance between the points, the dividing line is m:n ratio, finding the mid-point of the line, etc.

Point A is located at (2, 6), and point M is located at (−1, 8). If point M is the midpoint of segment AB.

Then the coordinate of the point B(x₁, y₁) will be

We know that the mid-point formula

[tex]\rm (x, y)= \left ( \dfrac{x_1+x_2}{2}, \ \dfrac{y_1+y_2}{2} \right )\\\\(-1, 8)=\left ( \dfrac{2+x_2}{2}, \ \dfrac{6+y_2}{2} \right )\\\\ \dfrac{2+x_2}{2}=-1 \\\\2+x_2=-1\times 2\\\\x_2=-2-2\\\\x_2=4\\\\\dfrac{6+y_2}{2} =8\\\\6+y_2=8\times 2\\\\6+y_2=16\\\\y_2=16-6\\\\y_2=10[/tex]

Then the coordinate point of B (x₁, y₁) is (−4, 10).

Hence, the coordinate point of point B (x₁, y₁) will be (−4, 10). Then the correct option is D.

Answer:

[tex]y = \frac{3}{4}x -3[/tex] --- Slope intercept

[tex]4y - 3x =- 12[/tex] --- Standard form

Step-by-step explanation:

Given

The attached linear graph

Required

The equation

Select any two points on the line

[tex](x_1,y_1) = (0,-3)[/tex]

[tex](x_2,y_2) = (4,0)[/tex]

Next, calculate the slope (m)

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

So, we have:

[tex]m = \frac{0 --3}{4 - 0}[/tex]

[tex]m = \frac{3}{4}[/tex]

The slope intercept is then calculated using:

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

So, we have:

[tex]y = \frac{3}{4}(x - 0) -3[/tex]

[tex]y = \frac{3}{4}(x) -3[/tex]

[tex]y = \frac{3}{4}x -3[/tex]

Multiply through bu 4

[tex]4y = 3x - 12[/tex]

Subtract 3x from both sides

[tex]4y - 3x =- 12[/tex] --- Standard form

Answer:

x = 89°

Explanation:

The angles inside a triangle will always add up to 180°

49 + 42 = 91

180 - 91 = 89°

Answer:

  (a)  1

Step-by-step explanation:

For large variable magnitude, the value of a rational function approaches the ratio of the highest-degree terms of the numerator and denominator*. Here, that is ...

  x/x = 1

f(x) approaches 1 as x approaches infinity.

__

* The function approaches the line or curve defined by the quotient. (The remainder is ignored in this case.) Here, f(x) = 1 + 3/(x-3), so the quotient is the constant 1.

Answer:

1.2 dollars

Step-by-step explanation:

You have to divide the dollar count by the pound count.

So basically:

6/5

This gives you 1.2 dollars.

When you do unit rate, you just have to divide one value by the other value.

The value you divide by, and the value you divde, vary depending on what the question asks.

For instance, if this question asked what the pound count for 1 dollar would be, you would end up divide the 5 pounds by 6 dollars(5/6) instead of divideing the 6  dollars by 5 pounds like we did above(6/5).

Hope this helps!

Answer:

4 1/2

Step-by-step explanation:

2/3 of 6 3/4 = 4 1/2

because "of" in math means multiply

so 2/3 x 6 3/4 = 4 1/2

4 1/2, because;

Convert any mixed numbers to fractions.

Then your initial equation becomes: 27/4 x 2/3

then applying the " formula for multiplication", 27 x 2

                                                                                 4 x 3

would equal = 54/12

Simplifying 54/12, the answer is 4 1/2

Answer:

{ -6, -4, -2}

Step-by-step explanation:

Since x > - 8, x can be any number greater than - 8.

x = -7, -6, -5, -4,...

BUT, it can't be equal because it's not using this sign [tex]\geq[/tex]

--------------------------------------------------------------------------------

--------------------------------------------------------------------------------

1. { -10, -8, -6} can't be an inequality of x because it has -10, -8.

2.{ -8, 0, 8} can't be an inequality of x because of -8.

3.{ -9, 1, 7} can't be an inequality of x because -9 isn't greater than x.

a). [tex]$\text{Set up hypothesis}$[/tex]

    [tex]$\text{Null hypothesis}$[/tex] : There is no significance between them.

                                  [tex]$H_0:\mu_1=\mu_2$[/tex]

    [tex]$\text{Alternate hypothesis}$[/tex] : There is significance between them.

                                 [tex]$H_1:\mu_1!=\mu_2$[/tex]

b). Test statics

    [tex]$X(\text{mean}) = 2.214$[/tex]

    Standard deviation [tex]$(s.d1)=1.718; \text{Number}(n_1)=20$[/tex]

    [tex]$Y(\text{mean})=2.0115$[/tex]

     Standard deviation [tex]$(s.d2)=1.8917; \text{Number}(n_2)=20$[/tex]

     We use the test statics :

  [tex]$t=\frac{X-Y}{\sqrt{\frac{s.d1^2}{n_1}+\frac{s.d2^2}{n_2}}}$[/tex]

 [tex]$t_0=\frac{2.214-2.0115}{\sqrt{\frac{2.95152}{20}+\frac{3.57853}{20}}}$[/tex]

 [tex]$t_0=0.35$[/tex]

Answer:

100 or 150 units of the product.

Step-by-step explanation:

R = x(1000-4x)

What is the value of x if R = 60,000?

x(1000-4x) = 60000

-4x^2 + 1000x = 60000

x^2 - 250x = -15000

x^2 - 250x + 15000 = 0

Factorize:

(x-100)(x-150) = 0

x-100 = 0 V x-150 = 0

x = 100 V x = 150

thenks and make me the brainliestt :))

Answer:

Below.

Step-by-step explanation:

For the answer including the red historgrams(image 3), the answer is A

this is because there is only 1 value that is between 1-2, which eliminates B. There is 1 value between 2-3 eliminating D. Finally, there is A and C.

C is funky, only having values for .1 to 1.1 for the first frequency. Since ther arent any values between 0.1 and 1.1, this cannot be a ansser.

So its A.

For the 4th image, its D.

This is because it asks what the first segment on the chart means.

The segment is 0-5 miles. This means people drive 0-5 miles . This is the first segment on the chart, and is very short

So we can conclude the answer os:

People drive a short distance to work.

Or as D puts it:

D - The number of people with a short drive to work.

Now we have the last(5th image)

The answer is C.

This is because we look at the values between 0-5, and 0-10.

When looking at the values 0-5, we can see only 3 fit(1, 4, 4)

C has only 1 value between 0-5, and D has 4. This isnt 3, so these cannot be right.

Now we have A and B, which are between 0-10.

There are 4 values we can see fit this(1, 6, 4, 4)

A has 5 values between 0-10, whereas B has 4 values, so it must be B.

For the first image, it says "the data set" implying that it says what this data set is.

For the second image, it is a bit similar.

I couldnt find a way to solve either of these without more information, could you take a picture of the whole entire page, just so I can make sure there isnt any missing info? Thanks, if there just isnt whatsoever, then I honestly have no clue how to do it.

I hope the answrs for 3, 4, and 5th image help!

Answer:

$15.75

Step-by-step explanation:

[tex]\frac{y}{15} :\frac{5}{100}[/tex]

y × 100 = 5 × 15

100y = 75

100y ÷ 100 = 75 ÷ 100

y = 0.75

$15 - $0.75

$14.25

[tex]\frac{y}{15} :\frac{10}{100}[/tex]

y × 100 = 10 × 15

100y = 150

100y ÷ 100 = 150 ÷ 100

y = 1.5

$14.25 + $1.50

$15.75
