Answers
Answer:
1. sin and cos 2. complementary 3. sinA = cosB 4. 80° 5. 17
Step-by-step explanation:
1. cofunctions: having the same value at complementary angles
sin θ = cos (90 - θ), or cos θ = sin(90 - θ)
2. complementary: two angles sum to 90°, supplementary: two angles sum to 180°
one of the angle in a right triangle must be a right angle = 90°
180°(sum of angles of a triangle) - 90° = 90°(the sum of the other two angles) => which is complementary
3. sinA = cosB
4. cos θ = sin(90 - θ)
=> cos 10° = sin(90 - 10°)
=> cos 10° = sin(80°)
5. sin θ = cos (90 - θ)
=> sin 73° = cos (90 - 73°)
=> sin 73° = cos (17°)
A number x, rounded to 2 decimal places is 7.42 write down the error interval for x
Answers
Answer:
7.415 ≤ x < 7.425
Step-by-step explanation:
The number x was rounded to 2 decimal places to give 7.42.
Since rounded off to 2 decimal places, the error interval for x is half of 0.01 subtracted from and added to 7.42.
Thus;
7.42 ± (0.01/2)
(7.42 - 0.005),(7.42 + 0.005)
7.415, 7.425
Now, 7.425 will not be included in the internal because approximating it doesn't give 7.42.
Thus,the error interval is;
7.415 ≤ x < 7.425

Ruth uses healthy credit to finance $2,200 for a hearing aid how much would she have to pay each month to pay back the loan in exactly 1 year
Answers
Answer:
$183.3
Step-by-step explanation:
Ruth uses healthy credit to finance $2,200 for a hearing aid how much would she have to pay each month to pay back the loan in exactly 1 year
Ruth took a loan of $2,200
1 year = 12 months
Hence, the amount she would be paying monthly is calculated as:
$2,200/12 months
= $2,200/12
= $183.33333333
Approximately = $183.3
Therefore, Ruth would be paying $183.3 monthly.

A map is placed on a coordinate grid. on the map, city 1 is located at (35,78) and city 2 is located at the point (47,122). If each unit is equivalent to 1 mile, how far apart are the cities?
A. (82,100)
B. (41,100)
C. (6,22)
D. (12,44)
Answers
Answer:
D
Step-by-step explanation:
Firstly, the question is phrased very very badly as the four answers provided are coordinate points rather than how far apart the cities are in units.
To calculate the distance between two points, we have to use Pythagoras' Theorem as it's just pretty much a right-angle triangle. Please look at the (terribly drawn) image provided.
Keep in mind that these points are only roughly placed on the map.
But firstly, to use Pythagoras' Theorem (a^2 + b^2 = c^2), we must find the length of the two sides.
To find the length of the horizontal line (which from now on I'll refer to as 'a'), we must subtract the smaller x value from the larger one.
47 - 35 = 12
To find the length of the vertical line (which from now on I'll refer to as 'b'), we must subtract the smaller y value from the larger one.
122 - 78 = 44
I assume that the answer you should pick is D. (12, 44)
However, that doesn't exactly answer the question... it's worded a little weirdly.
To solve the rest of the equation, do the following:
Now that we know that the length of a = 12 and the length of b = 44, we can use Pythagoras' Theorem.
a^2 + b^2 = c^2
12^2 + 44^2 = c^2
144 + 1936 = c^2
2080 = c^2
c = [tex]\sqrt{2080}[/tex]
c = 45.61
The answer is 45.61 units.

Distance traveled in miles = 10 miles
Time taken = 1 hour 20 minutes
In other to express average speed on terms of miles per hour :
Time in hour = 80 / 60 = 1.333333 hours
Average speed = Distance traveled / time taken
Distance = 10 miles / 1.33333 hours

Answer:
a=55
b=55
c=125
d=125
e=55
f=55
g=125
Step-by-step explanation:
Answer:
∠a = 55°, ∠b = 55°, ∠c = 125°, ∠d = 125°, ∠e = 55°, ∠f = 55°, ∠g = 125°
Step-by-step explanation:
straight lines form 180°:
125° + ∠a = 180°
=> ∠a = 55°
verticle angles are congruent:
∠c = 125°
∠b ≅ ∠a => ∠b = 55°
When two line are parallel:
same side interior angles are congruent:
∠g ≅ ∠c => ∠g = 125°
∠e ≅ ∠a => ∠e = 55°
∠d = 125°
∠ f ≅ ∠b => ∠f = 55°

Carlos cut StartFraction 5 Over 12 EndFraction of a yard of cloth into 5 pieces of equal length. What was the length of each piece of cloth?
Answers
Answer:
Each piece of cloth is (1/12) of a yard long.
Step-by-step explanation:
Carlus cut 5/12 of a yard of cloth into 5 pieces of equal length.
To find the length of each piece of cloth, we need to find the quotient between the length of the piece of cloth, and the number of pieces in which we divide it.
This is:
length = [tex]\frac{(5/12)yd}{5} = \frac{5yd}{12*5} = \frac{1yd}{12} \frac{5}{5} = \frac{1 }{12} yd[/tex]
This means that the length of each piece of cloth is (1/12) of a yard long.
