Answer:

A=80

B=31

C=64

Step-by-step explanation:

A, 69, and b will equal 180 since it forms a straight line

A+69+b=180

to solve for A we subtract 53+47 from 180 and get 80

80+69+b=180

to get B we subtract 80+69 from 180 and get 31

to get c we add 85+b and subtract it from 180 getting c=64

Answer:

Hey it's me again the life saver ;)

To find b we can use the linear pair property but since only 1 angle is given, we owuld need at least 2 angles on this situation to find b so, to do that we are first going to find a

a=>

53 + 47 + a = 180

a=180 - 100

a=80°

Now to find b=>

80 + 69 + b =180 (Because of Linear pair property)

b = 180-149

b=31°

Now that we have got b, to solve c, we can again use the sum of all angles in a triangle are 180°

c=>

31 + 85 + c =180

c=180 - 116

c=64

Answer:

1 foot

Step-by-step explanation:

1 yard = 3 ft

[tex]2*1 yard= 2*3feet[/tex]

2 yards = 6 feet

[tex]\frac{1}{6}[/tex] (2 yards) = [tex]\frac{1}{6}[/tex] (6 feet)

So, [tex]\frac{1}{6}[/tex] of 2 yards is 1 foot.

Step-by-step explanation:

The lines are parallel to one another.

A linear system of equations has no solution if the graphs are parallel and the two lines never meet.

An equation is a statement that two expressions, which include variables and/or numbers, are equal. In essence, equations are questions, and efforts to systematically find solutions to these questions have been the driving forces behind the creation of mathematics.

There can be one solution to a system of two linear equations, an infinite number of solutions, or no solutions at all. The number of solutions to a system of equations can be used to categorize it.

A system is deemed consistent if there is at least one solution to the problem. A consistent system is said to be independent if it only has one possible outcome.

Thus, a linear system of equations has no solution if the graphs are parallel and the two lines never meet.

Answer:

A

Step-by-step explanation:

Im not sure if this is right, but I think that is the answer

If we solve each of the expression then (n-p) will have the lowest value.

Expression is like an equation and it is not only in the equal to type but only without equal to type. (n-p), np are the expressions.

We have the following expression and we have to first solve if n is a negative number and p is a positive number.

Let n=-1 and p=2

So, n-p=-1-2=-3

[tex]n^{2} p[/tex]=2

[tex](np)^{2}[/tex]=4

p-2n=0

[tex](n-p)^{2}[/tex]=9

Hence the lowest value is of n-p which is -3.

The results for the addition operation are obtained as  84⁵/₉,  6²/₉,  -23.24 and 131.87 respectively.

The arithmetic operations are the fundamentals of all mathematical operations. The example of these operators are addition, subtraction, multiplication and division.

The given problem can be solved as follows,

(a) 45²/₉ + 39³/₉

⇒ 45 + 2/9 + 39 + 3/9

⇒ (45 + 39) + (2/9 + 3/9)  = 84⁵/₉

(b) -24⁵/₉ + 30⁷/₉

⇒ -24 - 5/9 + 30  + 7/9

⇒ (-24 + 30) + (7/9 - 5/9)

⇒ 6²/₉

(c) 28.98 + (-52.22)

⇒ 28.98 - 52.22

⇒ -23.24

(d) 56.75 + 75.12

⇒ 131.87

The given arithmetic operation can be matched in the form of table as,

    Sum                                    Result

45²/₉ + 39³/₉                             84⁵/₉

-24⁵/₉ + 30⁷/₉                            6²/₉

28.98 + (-52.22)                     -23.24

56.75 + 75.12                           131.87  

Hence, the given numbers are added to give result as 84⁵/₉,  6²/₉,  -23.24 and 131.87 respectively.

Answer:

Step-by-step explanation:

we have a right triangle,

to find out the hypotenuse, h

H^2=13^2+4^2

H^2=169+8=177

The required equation would be x² = 13² + 4² which is determined by Pythagoras theorem that is used to the length of the Ladder needed to reach the window.

A right triangle is defined as a triangle in which one angle is a right angle or two sides are perpendicular.

Pythagoras theorem states that in a right-angled triangle, the square of one side is equal to the sum of the squares of the other two sides.

We have given that the window is 13ft above the ground and the base of the ladder is 4ft from the building

As per the condition, We have a right triangle.

To find out the hypotenuse x

By Pythagoras theorem,

⇒ x² = 13² + 4²

⇒ x² = 169 + 8

Therefore, the equation would be x² = 13² + 4²which is used to determine the length of the Ladder needed to reach the window.

Hence, the correct answer would be an option (A).

Answer:

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

Step-by-step explanation:

[tex]\frac{1}{6}[/tex] +  [tex]\frac{1}{6}[/tex]

This is because there is only one "5" and one "6" in a dice. Moreover the total number of numbers in a dice are 6 so the denominator will be 6. Then when the word 'or' is present it means that both the probabilities must be added.

P (of rolling a 5 or 6 on a fair dice) = [tex]\frac{1}{6}[/tex] +  [tex]\frac{1}{6}[/tex]

[tex]\frac{2}{6}[/tex] can be simplified further. Both 2 and 6 are factors of 2 so..

[tex]\frac{2}{6}[/tex] = [tex]\frac{1}{3}[/tex]

Step-by-step explanation:

Lola's pet turtle walked 10 feet, and then half that length again. This means that Lola's pet turtle walked:

= 10 + (1/2 × 10) = 10 + 5 = 15 feet

Lola's baby brother walked 3 feet, and then half that length again. Total length walked will be:

= 3 + (1/2 × 3) = 3 + 1.5 = 4.5 feet

Lola's hamster walked 6.5 feet, and then half that length again. Total length walked will be:

= 6.5 + (1/2 × 6.5) = 6.5 + 3.25 = 9.75

Lola's mom walked x feet, and then half that length again. Total length walked will be:

= x + (1/2 × x) = x + 0.5x = 1.5x

Total feet walked by the whole member of the family will be:

= 15 + 4.5 + 9.75 + 1.5x
