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°.

Problem 2: Raylin wants to buy a new bike for $85. She already has $22 saved and her mom will
give her $2.50 for each chore she does. What is the least amount of chores Raylin must do in order
to save enough money to buy the bike?
Answer
22
23
24
25
26
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

find the intercept of the line please help
Answer:
x-intercept: -5/2
y-intercept: 15/4
Step-by-step explanation:
to find x-intercept set y = 0
-6x + 4(0) = 15
-6x = 15
x = -15/6
x = -5/2
to find y-intercept set x = 0
-6(0) + 4y = 15
4y = 15
y = 15/4

Answer:
so C but might be A
Step-by-step explanation:
Two quantities have a proportional relationship if they can be expressed in the general form y = kx, where k is the constant of proportionality. In other words, these quantities always maintain the same ratio. That is, when you divide any pair of the two values, you always get the same number k.

Carla was asked to draw all the lines of symmetry for a regular pentagon. She drew
the picture below. What was Carlas mistake? Explain in detail what she did wrong
and what the correct image would look like.
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 straightSymmetry
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

Answer:
the ratio of wheat cereal to rice cereal is 1:6 and the value is 1/6 or 0.16666
Step-by-step explanation:
if 1 1/2 = 1/4 then ?=4/4
since we know the value of 1/4 we multiply 1 1/2x4=6 and 1/4x4=1 so the ratio is 1:6. The value of the ratio is the quotient, and the quotient of 1 and 6 is 1/6 or 0.16666

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

The solution is the point of intersection of the lines.
Read that point off the graph.
Start from the point where the x-axis and the y-axis intersect. Go left 1 unit. That is x = -1. Now go down 2 units. That is y = -2. The point that has x-coordinate -1 and y-coordinate -2 is the point (-1, -2). That is the solution.
The point is (-1, -2).
