Answer:

i am so sorry but i need points a=5

Answer:

∠ATB = 102°

Step-by-step explanation:

Since ∠CBY is less than 90°, CB is not a diameter.

I did this in my head so I drew a sketch to show that around about way I did it. sketch attached:

I drew a third line from X to Y that is tangent to the circle at C.

Because each pair of tangent lines to a common point are equal, we have made three isosceles triangles.  

Now we know 2 of the three angles to ΔXYT, 180 - 50 - 28 = 102° for ∠ATB

Answer:

Step-by-step explanation:

Given

To find

Solution

Refer to attached picture

TAX is a straight angle and:

∠TBA = ∠TAB as two tangents intersect at same distance, their opposite angles are therefore same. ΔATB is an isosceles triangle.

Answer:

4 / 6

Step-by-step explanation:

Fred fraction = 2/3

Sarah formed a fraction by dividing her number line into 6 equal pieces. This is given as;

x / 6

Since her fraction is equal to that of fred, we have;

x / 6 = 2 / 3

x = 6 * 2 / 3 = 4

Sarah Fraction = 4 / 6

Answer:

  Step 2 is where the error lies.

  The solution is x > 6

Step-by-step explanation:

The rules for solving inequalities are substantially similar to the rules for solving equations. If you perform the same operation on both sides of the comparison, the value of the variable does not change. (The exception is when that operation is an "order-reversing" operation. See comment below.)

Kahal's steps would be expected to be the same ones you would use:

  Step 1: 4x -4 > 20 . . . given

  Step 2: 4x > 24 . . . add 4 to both sides

  Step 3: x > 6 . . . . . divide by 4

We note that our Step 2 is different from Kahal's Step 2. In Step 2 is where his mistake was made. He added 4 to one side and subtracted 4 from the other side.

Exception (order-reversing operations)

The operation you will usually run across in high-school algebra that will reverse ordering is multiplication (or division) by a negative number. Consider, for example, ...

  1 < 2

  -1 > -2 . . . . . both sides of the inequality multiplied (or divided) by -1

Notice that the order has been reversed: the larger magnitude number is now "less than".

Answer:

angle v = 46 degrees

Step-by-step explanation:

tan-1 = [tex]\frac{opposite}{adjacent}[/tex]

tan-1 V = [tex]\frac{21}{20}[/tex]

[tex]\frac{21}{20}[/tex] = 1.05

tan-1 V = 1.05

V = 46.397

round to the nearest whole number:

46.397 = 46

Answer:

Step-by-step explanation:

If it is exponential dividing any term by the preceding term will be a constant, the common ratio or rate. 50/25=100/50...=2 The initial value, a, (at x=0) is 25 so the general form is

y=ar^x we have a=25 and r=2 so

y=25(2^x)

Answer:

a = 19

Step-by-step explanation:

a=2b-c

a= 2(11) - 3

a = 22 - 3

a = 19

Answer:

a = 19

Step-by-step explanation:

2 x 11 = 22 - 3 = 19

So a = 19

h/26=6/8

h=26(6)/8

h=19.5 ft

Answer:

m = 3/2

Step-by-step explanation:

You want to find the slope, or the change in y coordinates over change in x-coordinates.

The first given point is E(-2, -4)

The second point is F(2, 2)

Coordinates are given in (x, y), so following the equation and computing the  x and y coordinates of E - F for both the numerator and denominator:

[tex]\frac{y_2 - y_1}{x_2-x_1} = \frac{-4 -2}{-2 -2} = \frac{-6}{-4} = \frac{3}{2}[/tex]

You could also have went the other way and calculated F - E for the numerator and denominator and get the same answer.

Finally, to check you can also look at the graph through the rise over run (rise/run) method and see that from E, you go up 3 (rise) and to the right 2 (run) to get to the next point on the line.

Answer:

Use the slope-intercept form to find the slope and y-intercept.

Slope: −3 . y-intercept: (0,4)

Any line can be graphed using two points. Select two x values, and plug them into the equation to find the corresponding y values.

X   Y

0    4

3/4  0

Graph the line using the slope and the y-intercept, or the points.

Slope: −3.  y-intercept: (0,4)

x    y

0    4

4/3 0

Answer:

213.042  km

Step-by-step explanation:

We need to convert 213 km 42 m to km.

We know that,

1 km = 1000 m

or

1 m = (1/1000)km

So,

42 m = (42/1000) km

It means,

[tex]213\ km\ 42\ m=213\ km+\dfrac{42}{1000}\ km\\\\=213.042\ km[/tex]

So, the required answer is 213.042  km.

Answer:

(1/3) * (3/8) = 1/8

Step-by-step explanation:

Multiple: 1/3* 3/8

= 1 · 3/3 ·8

= 3/24

= 1  3/8·3

= 1/8

Answer:

C

Step-by-step explanation:

(180- 80+65 = 35) sum of the angle in a triangle.

to get the exterior angle

180 - 35 = 145 (sum of angle on a straight line is 180)

...C. 145° on Ap3x.....

Answer:

A, B, and E

Step-by-step explanation:

When talking about like terms you need to look at the variable. You have to look at which has the same variables and then you can determine which are like terms.

For A --> -6m + 4m both have m as a variable. They can be combined. Which is why they are like terms. Do the same for the rest.

What would NOT be like terms?

C-- 10m + mn

This is wrong because of the variable. the variable for 10m is m. When there is only a variable you can pretend there is a 1 (For example, m can be 1m but we ignore that). mn is a variable as a whole. So if we added one to the front, the variables of 10m and 1mn would not match! It does not matter if they both have an m, because the value would be different either way.

Hope this helps!!

Step-by-step explanation:

a) Common Difference = ?

15th term = 110

19th = 134

134 - 110

= 24/4

= 6

Common Difference = 6

b) First term = ?

110 = x+ (14) 6

x = 110 - 84

x = 26

First term = 26

c) 25th term = ?

= x 25 = 26+ (25)6

= x 25 = 176

25th term = 176.

Answer:

32.5

Step-by-step explanation:

23x6÷4-2 and that's how you get your answer

a.  Equation:

3x + 21 = 6x - 60           {measure of corresponding angles is the same}

3x - 6x = -60 - 21

- 3x = - 81

b. Value of x:

  x = 27

c.  Ange measures:

3x + 21 = 3×27 + 21 = 81 + 21 = 102°

or:

6x - 60 = 6×27 - 60 = 162 - 60 = 102°
