Answer 1

Answer:

a - 8.5ft

Step-by-step explanation:

() Using trig ratio

sin(45) = x/12

12 * sin(45) = x

x = 8.5

() Using Pythagorean theorem

*special right triangle*

Since x * [tex]\sqrt{2}[/tex] = 12

to find the legs

x = [tex]\frac{12}{\sqrt{2}}[/tex]

x = 8.5

Answer 2

Answer:

x ≈ 8.5

Step-by-step explanation:

You  have a 45- 45 -90 right triangle.  The hypotenuse = 12, the legs = x

   a² + b² = c²

 x² + x² = 12²

  2x² = 144

    x² = 72

    x = [tex]\sqrt{72}[/tex]

     x = 8.485 ;  x≈ 8.5

  or in a a 45- 45 -90 right triangle the hypotenus =  the leg([tex]\sqrt{2}[/tex] )

You are given the hypotenuse = 12.  Finding x value

    hypotenus = leg ([tex]\sqrt{2}[/tex])

         12 =  x([tex]\sqrt{2}[/tex] )

         12/[tex]\sqrt{2}[/tex] = x

         8.485 ≈ x

          8.5 ≈ x

Group of answer choices

20°

70°

90°

180°

Answers

Answer:

20°

Step-by-step explanation:

Rotation is one of 3 basic rigid transformation, it will not change the original shape and size. Therefore angle B' should be still 20°

The degree measurement of angle B′ will be same as angle B that is 20°. Then the correct option is A.

What is a transformation of a shape?

A point, line, or geometric figure can be transformed in one of four ways, each of which affects the structure and/or location of the object.

From before the refers to the object's initial condition, and Picture, after transformation, refers to the object's ultimate structure and location.

Rotation does not change the shape and size of the geometry. But changes the orientation of the geometry.

If the geometry is rotated, then there is no change in anlges.

Britton rotated trapezoid ABCD 180° on the coordinate plane. If angle B is 20° and angle D is 90°.

The degree measurement of angle B′ will be same as angle B that is 20°.

Henry and his little brother made up a game using coins. They flip the coins towards a cup and receive points for every one that makes it in. Henry starts with 15 points, and his little brother starts with 20 points. Henry gets 3 points for every successful shot, and his brother, since he is younger, gets 2 points for each successful shot. Eventually, the brothers will have a tied score in the game. How many additional shots will each brother have made?
Write a system of equations, graph them, and type the solution.

Answers

Answer:

After 5 additional shots, the brothers will have a tied score.

Step-by-step explanation:

find equations

henry:

y-int is 15 because that is the starting number. the slope is 3 because that is how much his points are increasing for every successful shot. we can use this information to form this equation:

y = 3x + 15

brother:

y-int is 20 because that is the starting number. slope is 3 because that is how many points he gets for each successful shot. using this information, we can form the following equation:

y = 2x + 20

--

solve

y = 3x + 15

y = 2x + 20

3x + 15 = 2x + 20

x + 15 = 20

x = 5

6 bananas cost the same as 4 oranges. 3 lemons cost the same as 1 orange. 2 limes cost the same as 1 lemon. How many limes cost the same as 1 banana?  ​

Answers

6 bananas(b) =4 oranges(o)

3 lemons(l) = 1 orange (o)

3x4 =12 so that lemons equal bananas we combine the equal factor of oranges

12 (l) = 1(b)

1 lemon (1) = 2 limes(li)

1 banana(b) = 12 lemons(l)

12(l) x 2limes so that we get the amount of limes per banana since 2 limes for every 1 lemon

1 banana = 12 lemons = 24 limes

If 6 bananas cost the same as 4 oranges. 3 lemons cost the same as 1 orange, one lime costs the same as half of one banana.

Let's assume the cost of one banana is represented by "B" and the cost of one orange is represented by "O". Based on the given information:

6 bananas cost the same as 4 oranges: 6B = 4O

3 lemons cost the same as 1 orange: 3L = 1O

2 limes cost the same as 1 lemon: 2L = 1O

Now, we need to find the cost of one lime in terms of bananas:

From equation 3, we can rewrite it as: L = (1/2)O

Substitute the value of O from equation 2 into the above equation: L = (1/2) * 3L

Now, we have the cost of one lime in terms of lemons. From equation 2, we know 3 lemons cost the same as 1 orange, so we can rewrite it as: L = (1/2) * (1/3)O

Now, substitute the value of O from equation 1 into the above equation: L = (1/2) * (1/3) * 6B

L = (1/2)B

Therefore, one lime costs the same as half of one banana.

PLEASE HELP ME!!! jacky starts biking to meet up with her friend. she knows that if she bikes at a speed of 10 mph, she will be 3 minutes late. jacky also know that if she bikes at a speed of 12 mph, she will be there 2 minutes before they agree to meet. how much time does she have left before the appointed time?

Answers

Answer:

27s

Step-by-step explanation:

d = distance to rendezvous point in miles

t = time of arrival at 10mph, i.e. 3 mins later than appointed time

10 mph = 10 miles per hour = ¹/₆ miles per min

12 mph = ¹/₅ miles per min

t = d/(¹/₆)

t = 6d

5 min = ¹/₁₂ hr

t - ¹/₁₂ = d/(¹/₅)

t = 5d + ¹/₁₂

Elimination of t:

6d = 5d + ¹/₁₂

d = ¹/₁₂ mi

t = 6(¹/₁₂)

t = ¹/₂ min

Time left to appointed time = ¹/₂ - ³/₆₀

= ¹⁰/₂₀ - ¹/₂₀

= ⁹/₂₀.min → 27 seconds

27 min
