A 20 foot ladder is placed against a wall at a 75 degree angle with the ground. The wall is perpendicular to the ground.
PART A: How high on the wall, in feet, will the ladder reach? Round your answer to the nearest tenth. Show your work.
PART B: What is the distance, in feet, from the wall to the base of the ladder? Show your work.
Answer:
Part A)
Height = 19.3 feet
Part B)
Distance = 5.2 feet
Step-by-step explanation:
Part A)
Let ladder reaches upto the h height of the wall.
[tex] \therefore \sin \theta =\frac{h}{length\: of\: the \:ladder} [/tex]
[tex] \therefore \sin 75\degree =\frac{h}{20} [/tex]
[tex] \therefore 0.9659258263 =\frac{h}{20} [/tex]
[tex] \therefore 0.9659258263\times 20 = h [/tex]
[tex] \therefore 19.3185165 \: ft= h [/tex]
[tex] \therefore h = 19.3 \: ft= h [/tex]
Part B)
Let the distance from the wall to the base of the ladder be x feet.
[tex] \therefore \cos \theta =\frac{x}{length\: of\: the \:ladder} [/tex]
[tex] \therefore \cos 75\degree =\frac{x}{20} [/tex]
[tex] \therefore 0.2588190451 =\frac{x}{20} [/tex]
[tex] \therefore 0.2588190451\times 20 = x [/tex]
[tex] \therefore 5.1763809 \: ft= x [/tex]
[tex] \therefore x = 5.2 \: ft [/tex]

If EG = 3y - 10 and ET = 2y, find the value of y In parallelogram FGHI.
1
Find Value of y.
=====================================
Work Shown:
EI = EG
3y-10 = 2y
3y-10-2y = 0
y-10 = 0
y = 0+10
y = 10
Note how if y = 10, then
EI = 3y-10 = 3*10-10 = 20EG = 2y = 2*10 = 20Both EI and EG are 20 units long when y = 10. This confirms the answer.
which describes a number that cannot be irrational?
Answer:
A number that can be written as the ratio of two integers .
Step-by-step explanation:
Irrational numbers are numbers those numbers that have infinite non-periodic decimals, that are reproduced in an unlimited way without an end point, without any part of the sequence being repeated. The set of irrational numbers, added to the rational numbers, configures the category of real numbers.
Irrational numbers include, for example, the famous number Phi (π), whose approximate value is 3.14 ..., extending its decimals indefinitely. These numbers are most often used in mathematical analysis.

a number that can be written as the ration of two integers

A battery factory typically produces 12,000 batteries per day and uses 50 boxes for packing the battiest. If the number of boxes needed for packing is proportional to the number of batteries produced, how many more boxes would be needed in a day when 18,000 battiest are produced
Answer:
Number of extra boxes= 120
Step-by-step explanation:
Giving the following information:
Batteries per box= 50
Number of batteries= 18,000
Number of batteries in ecxess= 6,000
We need to calculate the number of boxes required to cover the 6,000 extra batteries:
Number of extra boxes= number of batteries / batteries per box
Number of extra boxes= 6,000 / 50
Number of extra boxes= 120
pls help you i’ll give brainliest
The answer is 6+(-4) = 2
Answer:
2
Step-by-step explanation:
it's just like saying 6-4 is two a negative is like a positiveanswers for both boxes please
Step-by-step explanation:
-5x + 4y = 2
+ (9x - 4y = 6)
=> 4x = 8, x = 2.
Therefore -5(2) + 4y = 2, 4y = 12, y = 3.
The solution pair is (2,3).

Determine whether the statement is true or false. If the statement is false, make the necessary change(s) to produce a true statement.
To solve the system below by substitution, replace y in the second equation with 7−6x.
6x−y=7
2x+y=5
This statement is true.
This statement is false. To solve the system by substitution, replace x in the second equation with 7−6x.
This statement is false. To solve the system by substitution, replace y in the first equation with 7−6x.
This statement is false. To solve the system by substitution, replace y in the second equation with 6x−7.
Answer:
To solve the system below by substitution, replace y in the second equation with 7−6x.
==> False
This statement is false. To solve the system by substitution, replace x in the second equation with 7−6x.
==> False.
This statement is false. To solve the system by substitution, replace y in the first equation with 7−6x.
==> False
This statement is false. To solve the system by substitution, replace y in the second equation with 6x−7.
==> True.
From the first equation, 6x-y=7
y= 6x-7
Answer: This statement is false. To solve the system by substitution, replace y in the second equation with 6x−7.

The Smith family is looking to rent a large truck for their upcoming move. With Rose's Moving, they would pay $40 for the first day plus $6 per additional day. With Riverside Rent-a-Truck, in comparison, the family would pay $90 for the first day plus $1 per additional day. Before deciding on which company to use, Mrs. Smith wants to find out what number of additional days would make the two choices equivalent with regards to cost. How many additional days would that be?
Answer:
10 days
Step-by-step explanation:
The Smith family is looking to rent a large truck for their upcoming move. With Rose's Moving, they would pay $40 for the first day plus $6 per additional day. With Riverside Rent-a-Truck, in comparison, the family would pay $90 for the first day plus $1 per additional day. Before deciding on which company to use, Mrs. Smith wants to find out what number of additional days would make the two choices equivalent with regards to cost. How many additional days would that be?
Let the number of additional days = x
With Rose's Moving, they would pay $40 for the first day plus $6 per additional day.
40 + 6x
With Riverside Rent-a-Truck, in comparison, the family would pay $90 for the first day plus $1 per additional day.
90 + x
Comparing both
40 + 6x = 90 + x
6x - x = 90 - 40
5x = 50
x = 50/5
x = 10
The number of additional days = 10 days
