What are the lengths of side AB and side BC?

What Are The Lengths Of Side AB And Side BC?

Answers

Answer 1

Answer: AB=20, BC=14

Step-by-step explanation:

set AB together with the side congruent to it (which is DC)

3x-7=x+11

subtract x and add 7 to both sides

2x=18

divide both sides by 2

x=9

plug 9 in for AB.

3(9)-7

27-7=20.

now do the same for BC

Answer 2

Answer:

AB = 20

BC = 14

Step-by-step explanation:

ABCD is a parallelogram

Opposite sides of a parallelogram are equal.

Therefore,

AB = DC

3x - 7 = x + 11

3x - x = 11 + 7

2x = 18

x = 18/2

x = 9

AB = 3x - 7 =3*9 - 7 = 27 - 7 = 20

7y - 7 = 3y + 5

7y - 3y = 7 + 5

4y = 12

y = 12/4

y = 3

BC = 7y - 7 = 7*3 - 7= 21 - 7 = 14

1.125°
2.115°
3.65°
4.55°

Answers

Answer:

3.) 65

Step-by-step explanation:

180-125=55

55+60= 115

a triangle equals 180

180-115=65

The sum of all the angles in a triangle is 180 degrees.

The value of the m∠ACR is 65°.

Option 3 is the correct answer.

What is the sum of angles in a triangle?

The sum of all the angles in a triangle is 180 degrees.

We have,

Line RCBT and ΔABC.

From the diagram, we see that,

In ΔABC,

m∠A + m∠B + m∠C = 180 ___(1)

m∠CBT = 180

m∠CBA + m∠ABT = 180

m∠CBA + 125 = 180

m∠CBA = 180 - 125

m∠CBA = m∠B = 55 ____(2)

m∠BCR = 180

m∠BCA + m∠ACR = 180 ____(3)

From (1) and (2) we get,

m∠A + m∠B + m∠C = 180

60 + 155 + m∠C = 180

m∠C = 180 - 60 - 55

m∠C = 65 ____(4)

From (4) we get,

m∠ACR = 65

Thus,

The value of the m∠ACR is 65°.

Option 3 is the correct answer.

Jack rode a bike through a new in the path shown at the right. If Jack took an average of 2 pictures per mile, how many pictures did Jack take on his bike ride?

Answers

Answer:

Jack took 10 pictures on his bike ride.

Step-by-step explanation:

Given that:

Given measurements of sides are 3 miles and 4 miles

We will find the distance of the new route by using Pythagorean theorem.

[tex]a^2+b^2=c^2[/tex]

(3)² + (4)² = c²

9 + 16 = c²

25 = c²

c² = 25

Taking square root on both sides

[tex]\sqrt{c^2}=\sqrt{25}\\c=5[/tex]

The distance of new route = 5 miles

Picture taken per mile = 2

Picture taken on bike ride = 2*5 = 10 pictures

Hence,

Jack took 10 pictures on his bike ride.

Answer:

The distance of two points  = 6 √2 = 8.4852

Step-by-step explanation:

Explanation:-

From the graph

Given points are  A ( 4,2) and B ( -2 , -4)  

The distance formula

       = [tex]\sqrt{(x_{2} -x_{1})^{2} + (y_{2} - y_{1})^{2} }[/tex]

( x₁ , y₁ ) = ( 4,2 )   and (x₂ , y₂) = ( -2 , -4)

The distance formula

       = [tex]\sqrt{(x_{2} -x_{1})^{2} + (y_{2} - y_{1})^{2} }[/tex]

     =[tex]\sqrt{(-2 -(4))^{2} + (-4 - (2))^{2} }[/tex]

  =   [tex]\sqrt{36+36} = \sqrt{72} = 6\sqrt{2}[/tex]

Step-by-step explanation:

sorry, im a bit late but hoping to help others that need the answer.

when you complete the square for a quadratic, you r answer can come in the form (x+p)^2+q.

in this form, p is the opposite of the x coordinate.

and q is the same as the y coordinate.

to get p and q from this, we find the opposite of the x coordinate and use the y coordinate we are given, and plug them into this equation.

we get: (x-2)^2+1

lets complete the equation now.

(x-2)^2 = x^2 - 4x + 4, then add the one we left out = x^2 - 4x + 5.

now our equation is in the same format as y=x^2+ax+b so we can just pull out the A and B which gives us:

A = -4

B = 5

The values of the given function for x=-2, 0 and 5 are -8, -2 and 13 respectively.

The given function is g(x)=3x-2.

What is the function?

Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.

Put x=-2 in the given function, we get

g(-2)=3(-2)-2

= -6-2

= -8

Put x=0 in the given function, we get

g(0)=3(0)-2

= -2

Put x=5 in the given function, we get

g(5)=3(5)-2

= 15-2

= 13

Therefore, the values of the given function for x=-2, 0 and 5 are -8, -2 and 13 respectively.

You can solve this using the Quadratic Formula, x =.

a = 1, b = -12, c = 59

x =    Multiply 4 and 1

x =    Multiply 2 and 1

x =    Multiply -4 and 59

x =    Square 12

x =    Subtract

x =    You can't find the square root of negatives, so factor the -92 out.

x =    You can find the square of 4, so take that out.

x =    Split the expression into two parts

x =  (+ or -)    The 2 in the numerator and the 2 in the denominator cancel each other out

x =  (+ or -)    Divide 12 by 2

x = 6 (+ or -)    Now, split the solution into the plus and minus parts.

a motorboat takes 5 hours to travel 150 Miles going Upstream. the return trip takes 3 hours going Downstream .what is the rate of the boat in still water and what is the rate of the current ?​

Answers

Answer:

Speed of boat in still water = 40 mph

Rate of current = 10 mph

Step-by-step explanation:

Let the speed of boat in still water be x & let the speed of the stream be y.

Total Distance = 150 miles

Time taken to travel during upstream = 5 hrs

Speed of the boat during upstream = [tex]\frac{150}{5} = 30\:mph[/tex]

Speed of boat during upstream can be represented as [tex]x - y = 30[/tex] because the boat is moving in the opposite direction of flow of stream.

Time taken to travel during downstream = 3 hrs

Speed of boat during downstream = [tex]\frac{150}{3} = 50\:mph[/tex]

Speed of boat during downstream can be represented as [tex]x+y=50[/tex] because the boat is moving in the same direction of flow of stream.

We got a pair of linear eqns. Let  [tex]x-y=30[/tex] be eqn.1 and [tex]x+y=50[/tex] be eqn.2 . Using substitution method ,

From eqn.1 , [tex]x-y=30[/tex]

[tex]=> x = y + 30[/tex]

Putting 'x' in eqn.2 , [tex]x + y = 50[/tex]

[tex]=> y + 30 + y = 50[/tex]

[tex]=> y + y = 50-30[/tex]

[tex]=> 2y = 20[/tex]

[tex]=> y = \frac{20}{2} = 10\: mph[/tex]

Putting y in eqn.1 ,

[tex]x - 10 = 30[/tex]

[tex]=> x = 30 + 10 = 40 \:mph[/tex]

Hence , the speed of boat in still water is 40 mph and speed of stream is 10 mph
