The length of the side a and b is 2.0837 and 11.8176 respectively.

Length of side a and b to be determine, hypotenuse is 12 and a is the length of the side opposite the 10 degree angle and b is the length of the opposite angle B.

Trigonometry is branch of mathematics that helps in elevation and angle problems.

Let assume that one angle of triangle is right angle.
So in right angles triangle,
hypotenuse = 12
cos10 =  length of b /12
length of b = 12 cos10
length of b = 11.8176

Now,
sin 10 =length of a/ 12
length of a = 12 sin10
length of a = 2.0837

Thus, the length of the side a and b is 2.0837 and 11.8176 respectively.

Answer:

(Use the attached formula)

24,000 for 4 years (48 months) at 2.75% interest

We divide rate by 1,200 which equals 0.0022916667

Monthly Payment = 0.0022916667 + {(0.0022916667 / [(1.0022916667)^48 -1]} * 24,000

Monthly Payment = 0.0022916667 + (0.0022916667 /  (1.1161375981  -1) * 24,000

Monthly Payment = [0.0022916667 + (0.0022916667 /  0.1161375981 ] * 24,000

Monthly Payment = [0.0022916667 +  0.0197323411 ] *24,000

Monthly Payment = 0.0220240078  * 24,000

Step-by-step explanation:

Perimeter of a polygon is the sum of measures of all sides of the polygon.

From the picture attached,

Distance run by Dallas = Perimeter of the ground

                                      = 48 + 50 + 9 + 30 + 30 + 30 + 9 + 50

                                      = 256 yards

Total warm up run by Dallas = 256 yards

7 trophies for $49.00

5 trophies for $30.00

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

Explination:

It says that she wants to pay no more than 7 dollars for each trophy she buys, which means 7 and less. So we have to multiply 7 x the number of trophies, And if it gives you the excact number or less its correct.

So we multiply

7 x 7 = 49 (The excact number, correct)

9 x 7 = 63 (The price they are selling it at is higher, incorrect)

12 x 7 = 84 (The price they are selling it at is higher, incorrect)

5 x 7 = 35 (Paying less, Correct)

3 x 7 (The price they are selling it at is higher, incorrect)

Answer:

14.85

Step-by-step explanation:

Answer:

14.85

Step-by-step explanation:

Or B for everyone else

First, write out the multiples of 6 and 26. Then find the common multiple they share that is immediately less than 85. (I do 26 first since it will have less multiple and it will give me an idea of what to look for within the multiples for 6)

26: 26, 52, 78 (anything more will be over 85 and we need a number less than 85)

6: 6, 12, 18, 24, 30, 36, 42, 48, 56, 72, 78 (I stopped at 78 since any number after this will be larger than 85)

I now look to find the multiple that both 26 & 6 shares that is also less than 85 and it landed me on the number 78!

The Answer: 78

Answer:

Step-by-step explanation:

The standard form equation is y = mx + k where m is the slope and k is the y-intercept.

In this problem, it is first asking you for the slope of y = 2x + k. Therefore, the slope would be 2. In the next blank, it is asking for the slope of y = -1/2x + k. In that case, it would have a slope of -1/2.

When you multiply these slopes together, you'll notice that the you'll get -1. Whenever the slopes of 2 equations multiplied together is equal to -1, then those 2 equations are perpendicular to each other.

Finally, it is asking if the statement that says the lines are perpendicular is true. Like mentioned above, because the slopes multiply to -1, they are perpendicular equations making the statement always true.

Answers: 2, -1/2, -1, always.

Answer:

Step-by-step explanation:

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

A(- 5, - 2) , B( - 1, - 6) , C ( - 9, - 6)

AB = √[(- 5 + 1)² + (- 2 + 6)²] = 4√2

BC = √[(- 1 + 9)² + (- 6 + 6)²] = 8

AC = √[(- 5 + 9)² + (- 2 + 6)²] = 4√2

D(2, 2) , E(6, - 2) , F( 10, 2)

DE = √[(2 - 6)² + (2 + 2)²] = 4√2

EF = √[(6 - 10)² + (- 2 - 2)²] = 4√2

DF = √[(2 - 10)² + (2 - 2)²] = 8

ΔABC ≅ ΔEDF

The two triangles ABC and DEF are not congruent by SSS.

The distance formula between two points is,

[tex]D = \sqrt{(x_2 - x_1_)^2 + (y_2 - y_1)^2[/tex].

Two triangles will be congruent by SSS is the distance of their corresponding sides are equal.

In ΔABC coordinates of A and B are (-5, - 2) and (-1, - 6).

[tex]D_{AB} = \sqrt{(- 1 + 5)^2 + (- 6 + 2)^2}[/tex].

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

[tex]D_{AB} = \sqrt{(16) + (16)[/tex].

[tex]D_{AB} = \sqrt{32}[/tex].

Similarly, the distance of DF in ΔDEF  is [tex]\sqrt{64}[/tex].

hence AB ≠ DF so the triangles are not congruent.

Answer: -6

if a=1 then -48a=-48

so when we divide by 8 we ger -48/8 which is -6

The solution to -48a divided by 8 when a =1  is -6.

A mathematical expression is a phrase that has a minimum of two numbers or variables and at least one mathematical operation.

Let's examine the writing of expressions. The other number is x, and a number is 6 greater than half of it. In a mathematical expression, this proposition is denoted by the expression x/2 + 6. Complex riddles are solved using mathematical expressions.

Given:

-48a divided by 8 when a =1 .

Now, put a=1 in -48a

=-48 x 1

=48

Now, -48 is divided by 8

=-48/8

= -6

Answer:

21

Step-by-step explanation:

Since exact coordinates aren't given, you would have to think of the two points on a number line. The distance from the two points on a number line would be 21. You could also add the absolute values of the two points together. This would basically turn -7 into a positive, and then when the absolute values are added(7 + 14), you would get 21.
