The floor of the entryway to an office building will be triangular. Two angles of the triangle will measure 40°, and the side between them will have a length of 8 meters. Make a scale drawing of the entryway using a scale of 1 cm : 2 m. Explain how you made your drawing.
Answers
Answer: The drawing in the attached figure
Step-by-step explanation: we know that
An isosceles triangle, has two equal sides and two equal interior angles
In this problem, the floor of the entryway to an office building is in the shape of an isosceles triangle
step 1
Find the measure of the vertex angle
Remember that
The sum of the interior angles in any triangle must be equal to 180 degrees
so
Let
x ---> the measure of the vertex angle of triangle
step 2
Find the length of the congruent sides of triangle
Applying the law of sines
Let
c ----> the length of one congruent side
we have
substitute
solve for b
step 2
Make a scale drawing of the entryway
The scale drawing is 1 cm : 2 cm
That means
1 cm in the drawing represent 2 cm in the actual
or
1 cm in the drawing represent 0.02 m in the actual
Find the dimensions in the drawing
For a=8 m
For b=5.22 m
step 3
Draw the triangle

Juli says she can use the patterns of equivalent ratios in the multiplication table below to write an infinite number of ratios that are equivalent to 6:10.
Which statement explains whether Juli is correct?
a. She is correct because she can multiply 6 and 10 by any number to form an equivalent ratio.
b. She is correct because 6:10 can be written as 1:2 and there are an infinite number of ratios for 1:2.
c. She is not correct because the multiplication table does not include multiples of 10.
d. She is not correct because 6:10 is equivalent to 3:5 and there are only 9 ratios in the multiplication table that are equivalent to 3:5.

After rounding off the obtained value, the value obtained in quarts will be equal to 3.17 qt.
What is rounding off values?The act of simplifying a number so that its value remains near to what it was is known as rounding. The outcome of rounding off a figure is less precise but simpler to utilize. They directly involve if a number's digits are taken into account while rounding it.
As per the given information in the question,
As we know,
1 liter = 1.057 quarts
Then, the number of quarts in 3 L will be equal to,
3 × 1.057
= 3.171 ≈ 3.17 qt

A cell phone battery with 22% charge takes 176 minutes to run out. How long will a fully charge battery last?
Answers
Answer:
800
Step-by-step explanation:
176 divided by 22=8
8x100= 800
It will take 13.33 hours to battery run out.
What is unit rate?A unit rate means a rate for one of something.
Given that, A cell phone battery with 22% charge takes 176 minutes to run out.
In 22% → 176 minutes
In 1% → 176/22 = 8 minutes
In 100% → 8x100 = 800 minutes
800 minutes = 800/60 = 13.33 hours.
Hence, the battery will work for 13.33 hours when charged 100%

The tables show the amount earned by James and Paco working at the same store.
What two equations can represent James and Paco's hourly wages, where h is the number of hours worked and d is the amount of money earned?
Compare the equations to determine if there is any difference between what James and Paco make each hour.
Answers
Answer:
Step-by-step explanation:
In order to determine if James and Paco earn different amounts of money per hour, you must find how much money they make in one hour.
James:
James makes $35.40 in 3 hours. So, in 1 hour, he would make 35.40/3 = 11.8.
James makes $11.80 an hour.
Therefore, his equation would be d = 11.8h
Paco:
Paco makes $24.00 in 2 hours. So, in 1 hour, he would make 24/2 = 12.
Paco makes $12.00 an hour.
Therefore, his equation would be d = 12h
Hence, Paco and James make different amounts of money. Paco makes 20 cents, or $0.20, more than James.
Answer:
d(James) = 11.8h
d(Paco) = 12h
Paco makes $0.20/h more than James
Step-by-step explanation:
equation: y = ax + b
James:
d(Amount of money earned) = ah(number of hours worked) + b
If James worked 3 hours: 3a + b = 35.4
If James worked 5 hours: 5a + b = 59
If
3a + b = 35.4
b = 35.4 - 3a
Then
5a + b = 59
5a + 35.4 - 3a = 59
2a = 59 - 35.4
2a = 23.6
a = 23.6/2
a = 11.8
If a = 11.8, then
3a + b = 35.4
3(11.8) + b = 35.4
35.4 + b = 35.4
b = 0
If a = 11.8 and b = 0
d(Amount of money earned) = ah(number of hours worked) + b
d = 11.8h
Each hour James works, he makes $11.8
Paco:
d(Amount of money earned) = ah(number of hours worked) + b
If Paco worked 2 hours: 2a + b = 24
If Paco worked 4 hours: 4a + b = 48
If
2a + b = 24
b = 24 - 2a
Then
4a + b = 48
4a + 24 - 2a = 48
2a = 48 - 24
2a = 24
a = 24/2
a = 12
If a = 12, then
2a + b = 24
2(12) + b = 24
24 + b = 24
b = 24 - 24
b = 0
If a = 12 and b = 0
d(Amount of money earned) = ah(number of hours worked) + b
d = 12h
Each hour Paco works, he makes $12

1/3 is not 1/2 or more than 1/2 so you have to round down.
Rounding to the nearest whole number involves writhing out the value of a number to the nearest integer value. Hence, the number would be written as 6

Answers
Answer:
Step-by-step explanation:
First, you should find the angle x because it will help in solving the angle y. A straight line adds up to 180 degrees, therefore x+y = 180
For the triangle on the left, sum up the angles and set it to 180 degrees.
60 + 38 + x = 180
x = 82 degrees
Now solve for y by doing this
82 + y = 180
y = 98 degrees
While I'm here, Ill solve for z because it will most likely ask in the next question.
26 + 98 + z = 180
z = 56 degrees

Answer:
The answer is C. But I got 350.82
Step-by-step explanation:
The area for one triangle is 24 because A=h(height)b(base)timesb(base)/2. Both the triangles together would make 48 because 24+24=48
The are for one rectangle is 100.94 because A=b(base) times h(height). because there are 3 rectangles we multiply 100.94 times 3 which is 302.82
Then we add up all the areas 302.82+48 to get 350.82
Because this answer is slightly different I would assume it is C.
