Answer:
x = 5.26 m
Step-by-step explanation:
Given that,
The angle of inclination = 20°
The vertical height of the ramp, h = 1.8 m
We need to find the length of the ramp. Let it is x.
We can find it using trigonometry. So,
[tex]\sin\theta=\dfrac{P}{H}[/tex]
We have,
P = 1.8 m, H = x
[tex]\sin20=\dfrac{1.8}{x}\\\\x=\dfrac{1.8}{\sin20}\\\\x=5.26\ m[/tex]
So, the length of the ramp is 5.26 m.

Answer:
[tex]sin 40 = \frac{x}{11}[/tex]
Step-by-step explanation:
[tex]sine = \frac{opposite}{hypotenuse}[/tex]
Side x is the opposite, since it is opposite the angle you are solving for.
Side y is the adjacent, since it is next to the angle you are solving for.
The side measuring 11 is the hypotenuse, since it is across from the right angle.

of the
40
students in her class could not give the correct answer.
What is the number of students who answered correctly?
Answer:
23
Step-by-step explanation:
find 10% = 4
quadruple it = 16
half 10% = 2
half it again = 1
2.5% = 1
40% = 16
1 + 16 = 17
take 17 off of 40 = 23

please be fast i don't understand it.
Answer:
Yes it is true. Sum of two integers is always an integer
Step-by-step explanation:
Rule: The sum of any integer and its opposite is equal to zero. Summary: Adding two positive integers always yields a positive sum; adding two negative integers always yields a negative sum. To find the sum of a positive and a negative integer, take the absolute value of each integer and then subtract these values.

24% of the eggs she collected in May were large.
(a) What percentage of the eggs she collected in May were medium?
Answer:
56% of her eggs were medium in may
Step-by-step explanation:
if 20% of the eggs she collected in May were small, 24% of the eggs she collected in May were large. All you have to do is add them up which is 44% and minus it by 100% which is 56%

Step-by-step explanation:
[tex]\frac{a}{6} = \frac{15}{2}[/tex] Original equation.
[tex]a = 6(\frac{15}{2})[/tex] To solve for a, multiply both sides by 6 to isolate a.

The equation of the proportional relationship represented by the table and the graph is: y = 2x.
What is a Proportional Relationship?If m is the slope or unit rate, a proportional relationship between two variables, x and y, can be represented with an equation as, y = mx.
Let's find the equation that represents the relationship represented by the graph and the table. Let's use the graph.
m = y/x
Using the point, (2, 4),
m = 4/2 = 2
Substitute m = 2 into y = mx
y = 2x
Therefore, the equation of the proportional relationship represented by the table and the graph is: y = 2x.

use the change flip method due to divide
Answer:
See step-by-step explanation.
Step-by-step explanation:
When dividing a fraction it is not actually dividing, it is more multiplying.
Our sum looks like this:
3/5 ÷ 1/3
The method here is to flip the second fraction and change the divide sign into a multiplication sign. Here is what is looks like step-by-step.
3/5 ÷ 1/3
3/5 ÷ 3/1
3/5 × 3/1
Now we can finish the sum off by multiplying across.
3 × 3 = 9
5 × 1 = 5
9/5, this is a top-heavy fraction.
If we want it as a mixed fraction then here it is:
1 4/5 (that is one and four fifths).
The kinetic energy of an object is given by the formula E = mv2. If m is in kg and v is in m/s,
then E is in joules. What is the kinetic energy of an electron (mass = 9.1 x 10-31kg) travelling at a
fifth of the speed of light (speed of light, c = 3 x 108m/s)?
Answer:
9.553×10^-26
Step-by-step explanation:
m= 9.1 ×10 ^-31
v = 3 × 108
= ( 9 .1 × 10 ^- 31) × ( 3 × 108 ) ^2
= 9 .552816 × 10 ^ -26
approximately
9.553×10 ^26
