Explanation:

Focus on triangle OCT. We can see that the triangle is isosceles because OT = OC are two radii of the same circle. That consequently means angles T and C are the congruent base angles (rotate the triangle to see what I mean). The base angles are opposite the congruent sides.

Since base angle C is 35 degrees, that makes base angle T this measure as well.

-----------

We just found angle CTO is 35 degrees. Angle PTO is supplementary to this, so it is 180-35 = 145 degrees.

Now focus solely on quadrilateral PTOQ. The goal is to find angle O, aka angle QOT. We found angle T in the paragraph above and it's 145 degrees. Angle Q is 90 degrees assuming segment PR is tangent to the circle at point Q.

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

Recall that for any quadrilateral, the interior angles always add to 360

let x be the measure of angle O, aka angle QOT

P+T+O+Q = 360

60+145+x+90 = 360

x+295 = 360

x = 360-295

x = 65

Therefore, angle QOT is 65 degrees

Answer: 1856.10

Step-by-step explanation:

Suzie will make $1856 in 4 weeks.

The first week 300

The second week: 300 x 30% + 300 = 390

The third week: 390x (1430%) = 507

The fourth week: 507 × (1430%) = 659.1

So Sum to: 300 +390 +507 +659.1 = 1856.1

Profit is $1856.

Answer:

x = 51

Step-by-step explanation:

Supplementary angles total 180º

(2x + 4) + (x + 23) = 180

Combine like terms

3x + 27 = 180

Subtract 27 from both sides

3x = 153

Divide both sides by 3

x = 51

Answer:

Hello! x = 51

Step-by-step explanation:

OMG I CAN ANSWER FINALLY!

it is forming a supplementary angle meaning it will add up to 180 degrees

51 × 2 = 102 102 + 4 = 106

51 + 23 = 74

106 + 74 = 180 therefore x = 51 Hope that helps.

Given:

Triangle EFG is congruent to triangle YXZ by ASA.

To find:

The other corresponding parts can be marked congruent by CPCTC.

Solution:

We have,

[tex]\Delta EFG\cong \Delta YXZ[/tex]

We know that the corresponding parts of congruent triangles are congregant (CPCTC). So,

[tex]\angle E\cong \angle Y[/tex]

[tex]\angle F\cong \angle X[/tex]

[tex]\angle G\cong \angle Z[/tex]

[tex]EF\cong YX[/tex], it is also written as [tex]FE\cong XY[/tex]

[tex]FG\cong XZ[/tex], it is also written as [tex]GF\cong ZX[/tex]

[tex]EG\cong YZ[/tex], it is also written as [tex]GE\cong ZY[/tex]

Therefore, the correct options are 2, 6 and 7.

Answer:

area = 2.28

Step-by-step explanation:

area of triangle is 1/2*b*h

area = (1/2)*3.8*1.2

area = 2.28

Answer:

2.28

Step-by-step explanation:

Area of triangle =(base*height)/2

And base=1.2 cm

Height=38 mm ( change it to cm as they need the answer in square cm) which is 3.8 cm

So (1.2*3.8)/2=2.28

Answer:

The square root of 4489 is:

Step-by-step explanation:

To find the square root by división method you must do the next:

1. you write the square root:

[tex]\sqrt{4489}[/tex]

2. You separe the number inside the square root in groups of two digits, begining by the right (in this case doesn't matter, because we have 4 digits, but remember this when the number has an odd number of digits):

√44 89

3. You must find a whole number which squaring gives us a number equal to or less than our first pair of digits (44), in this case is 6, because 6*6 = 36 and, if we take 7, 7*7 = 49 (we would pass):

√44 89 ║6

4. Now, we subtract the squaring of the number obtained to our first pair of digits:

√44 89 ║6

-36

= 8

5. We duplicate the root obtained (6) and we lower the next pair of digits next to the result of the previous subtraction, but this time we make pairs of digits from the left:

√44 89 ║6

-36       ║12

= 88 9

6. We divide 88 (our pair of digits) in 12 (the double of the obtained root):

88 ÷ 12 = 7.3333333 (we approximate to 7)

7. We put the number obtained in the division (7) to the right side of the double of the obtained root (12) and we multiply by this too:

√44 89 ║6

-36       ║127 * 7 = 889

= 88 9

8. we subtract the number obtained in the multiplication to the digits we order in pairs (889):

√44 89 ║6

-36       ║127 * 7 = 889

= 88 9

- 889

= 0

9. We raise the number that we multiply by twice the previous root found, as another digit of the root:

√44 89 ║67

-36       ║127 * 7 = 889

= 88 9

- 889

= 0

As you can see, the square root of 4489 with this method gave us the result 67.

Answer:

1/2

Step-by-step explanation:

Given data

Total melon= 1 1/2

In simple fraction= 3/2

DIvide 3/2 by 2

= 3/2/3

=3/2 * 1/3

=3/6

= 1/2

Hence each person will get 1/2 of  the whole water melon

Answer:

b = 5

Step-by-step explanation:

You want to get b on one side alone so you divide by 4.

20 divided by 4 is 5.

Answer:

b = 5

Step-by-step explanation:

4b = 20

Whatever we do to one side of the equation, we have to do to the other.

To "isolate the variable", or get "b" by itself, we have to divide both sides by 4

4b divided by 4 is b, since "4b = 4 times b"

20 divided by 4 is 5

4b = 20

b = 5

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

Explanation:

The phrasing "Depends on its speed" tells us that the speed is the independent variable, and therefore it's the x variable.

The domain is the set of allowed x values of a function, or allowed inputs. In this case, it appears the car's max speed is 100 mph.

Answer:

0 to 100 miles per hour

Answer:

Step-by-step explanation:

The angle (angle D) created by 2 tangents to a circle (DC and DA) is half of the difference between its intercepted arcs (arc ABC - arc AC):

[tex]65=\frac{1}{2}(x-[360-x])[/tex] If we don't know the measures of either of the arcs, but we DO know that the measure around the outside of a circle is 360 degrees, then we will call arc ABC "x", making arc AC "360 - x". Solving:

2(65) = 2x - 360 and

130 = 2x - 360 and

130 + 360 = 2x and

490 = 2x so

x = 245. This means that arc ABC is 245 and arc AC is 115.

Answer:

- [tex]\frac{1}{3}[/tex]

Step-by-step explanation:

The equation of a line in slope- intercept form is

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

y = 3x - 8 ← is in slope- intercept form

with slope m = 3

Given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{3}[/tex] ← slope of perpendicular line

Answer:

The Answer is B: We must find the opposite reciprocal of the slope of the line whose equation we were given.

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

Explanation:

List out the perfect squares

and so on. We can see that 46 is between 6^2 = 36 and 7^2 = 49.

We can say 6^2 < 46 < 7^2

Applying the square root to all three sides leads us to 6 < sqrt(46) < 7

Now multiply all three sides by -1. This will flip the inequality signs

We go from

6 < sqrt(46) < 7

to

-6 > -sqrt(46) > -7

It might help to order things from smallest to largest to get this

-7 < -sqrt(46) < -6

This means -sqrt(46) is between -7 and -6 on the number line

See the diagram below.

Answer:

Step-by-step explanation:

First notice that -√46 lies between -√49 and -√36, that is, between

                                                              -7   and  -6.  

Here all three numbers are negative because they lie to the left of zero (0) on the number line.

Answer:

side of base, a = 10.1 inches, height, h = 40.1 inches

Step-by-step explanation:

Volume of rectangular solid, V = 4096 cubic inches

Let the side of base is a and the height is h.

[tex]V = a^2h\\\\4096 = a^2 h ..... (1)[/tex]

surface area of the solid  

[tex]S = 2a^2 + 4 ah \\\\S = 2a^2 + 4 \times a \times \frac{4096}{a^2} from (1)\\\S = 2a^2 + \frac{4096}{a}\\\\\frac{dS}{da}= 4 a - \frac{4096}{a^2}\\\\4 a - \frac{4096}{a^2} = 0 \\\\a^3 = 1024\\\\a =10.1 inches[/tex]

So, h = 40.2 inches
