a 10 foot ramp must make an angle of 30° with the ground if it is to reach a certain window. what angle must a 15 foot ramp make with the ground to reach the same window

Answers

Answer 1

The 15 foot ramp must make an angle 19.45° with the ground to reach the same window.

What angle must be made with the ground by the 15 foot ramp?

Since the height of the window above ground remains constant in both cases, it follows that by means of trigonometric identity sine; we have;

10sin30° = 15sinx

sinx = 5/15 = 0.333

x = sin-¹(0.333)

x = 19.45°.

and what the correct image would look like.

Answers

Answer:

Simple, Her Pentagon is not straight

Step-by-step explanation:

Carla's Pentagon is not straight. Her symmetry line is off scale. Simply fix the Line on the pentagon And it will be correct.

Hope this helps ^

We have that the correct Pentagon should have

Her Pentagon lacks perpendicularity between the two base PointsHer Pentagon lacks perpendicularity between the two middle pointsThe vertical link to the top vertex is not straight

Symmetry

This can be defined as an exact correspondence between different part of a system .

Therefore it can be said that Carla's Pentagon lacks Symmetry

Where a

Pentagon

is defined as a a shape with five sides and five angles

In this sense the is absolutely nothing with Carla's Pentagon

But if Carla is going for a pentagon with equal sides and and, Then

Problem 2: Raylin wants to buy a new bike for $85. She already has $22 saved and her mom will

Answer
22

25
26

Answers

○=> Correct option :[tex]\color{plum}\tt\bold{(d) \: 25}[/tex]○=> Steps to derive correct option :

Cost of a bike Raylin wants to buy = $85

Money Raylin already has = $22

Money she needs :

[tex] = \tt85 - 22[/tex]

[tex] = \tt\$63[/tex]

Thus, money Raylin still needs = $63

Money she gets from doing one chore = 2.50

Number of chores the needs to do :

[tex] = \tt \frac{63}{2.50} [/tex]

[tex]\color{plum} =\tt 25 \: chores[/tex]

Thus, Raylin needs to do 25 chores to be able to buy the bike.

Therefore, the correct option is (d) 25

The highest point in Chicago is 735 feet above sea level. You can represent that numerically using .

Answers

Answer:

+735 feets

Step-by-step explanation:

Points or position above sea level are denoted with positive elevation values while points or positions below sea level are denoted by negative values. The sea level position itself could be viewed as a midpoint such as the position of 0 on a number line ; where distances to the right are positive and distances to the left are negative.

Hence, a point which is said to be 735 feets above sea level would have an equivalent numeric representation of +735 feets
