Solve for a side in right triangles
I don’t know how to do this so please someone teach me how to do this?? I need help here!
Answer:
2.33
Step-by-step explanation:
imagine a circle. its center is A, and it goes through B, so its radius is AB.
then it is important to know that the sum of all the angles in a triangle is 180 degrees.
one angle (at C) is 90. the angle at B is 25. so, the angle at A is 180 - 90 - 25 = 65 degrees.
more back to our circle.
in this circle the line CB is the sine of the angle at A multiplied by the radius.
and AC is the cosine of the angle at A multiplied by the radius.
we can ignore the orientation + and - of these functions, as we are only interested in the absolute length (and we can mirror the triangle, and all the angles and side lengths still stay the same).
=> CB = sin(A)×AB
AC = cos(A)×AB
=> 5 = sin(65)×AB
=> AB = 5 / sin(65)
=> AC = cos(65)×5/sin(65) = 5 × (cos(65)/sin(65)) =
= 5 × cot(65) = 2.33

answer the following questions.
1. The amount you spend at the fair can be represented by the function: y=2x+10
Which statement describes what's happening correctly?
a. For each additional game played, the cost increases by $10.
b. For each additional game played, the cost increases by $2.
c. For each additional game played, the cost increases by $8.
d. For each additional game played, the cost increases by $12.
2. What will the function f(x)=x^2 look like translated 3 units right and 8 units down?
Answer:
1.
This should have a context but based on the answer options we can say that option B is the correct one.
In the function y = 2x + 10
2 is the coefficient which makes change as x changes and 10 is the constant which is same for any value of x.2.
Translation left-right is displayed as:
g(x) = f(x + a) or g(x) = f(x - a) where positive a shows translation left.Translation up-down is displayed as:
g(x) = f(x) + b or f(x) - b where positive b shows translation up.If we apply the above to the given function we have:
g(x) = f(x - 3) - 8or
g(x) = (x -3)² - 8question 4, plz help ( radius is 6.8)
Answer:
A) 145.3 cm^2
Step-by-step explanation:
The formula for the area of a circle is A = π r^2
So to find the area we would plug the radius of 6.8 into the formula
Area = π (6.8)^2
Area = (3.14) (6.8)^2
Area = 145.27
Area = 145.3

Find the surface area of the cone. Round your answer to the nearest tenth.
The surface area is
30
m².
9514 1404 393
Answer:
113.1 m²
Step-by-step explanation:
The surface area of the cone is ...
SA = πr(r +s) . . . . . . where r is the radius and s is the slant height
SA = π(4 m)(4 m + 5 m) = 36π m² ≈ 113.1 m²
The surface area is about 113.1 m².

find the ratio of 2500g to 35kg
35kg - 3500g
3500g - 2500g
= 1000g
Answer:
1 : 14
Step-by-step explanation:
The measures must have the same units, that is both g or Kg
2500 g : 35 Kg
= 2500 g : 35000 g ( 1 Kg = 1000 g )
Divide both parts by 100
= 25 : 350 ( divide both parts by 25 )
= 1 : 14

The rule for a pattern is ''take half the number to get the next number.'' the first number in the pattern is 16 what is the next number?
Answer:
8
Step-by-step explanation:
Let the next number be x
'taking half the number to get the next number. is expressed as;
1/2 of 16 = x
x = 1/2 *16
x = 16/2
x = 8
hence the next number will be 8

7/32
Step-by-step explanation:
John and George together raked 7/8 of the yard. John raked 3/4 of that amount. What part of the yard did john rake?
Proportion of the yard Jake raked = 7/8 x 3/4 = 21/32
Portion of the yard Jake raked = 21/32 - 7/8 = 7/32

If two angles of a triangle have measures of 42° and 20°, what is the measure of the
third?
128°
118°
98°
108°
Answer:
118°
Step-by-step explanation:
the angle measures of a triangle will always add up to 180
so..
42+20=62
180-62=118
Answer:
118
Step-by-step explanation:
We know,
Sum of all angles of triangle is 180 degree.
Let, the third angle be x,
or, 42 + 20 + x = 180
or, 62 + x = 180
or, x = 180 - 62 = 118
Therefore, the third angle is 118 degrees

180= x + (180-107)+(x+ 13)
Answer:
x = 47
Step-by-step explanation:
180 = x + (180 - 107) + (x + 13)
Subtract in the parenthesis.
180 = x + 73 + x + 13
Combine terms.
180 = 2x + 86
Subtract 86 from both sides.
2x = 94
Divide both sides by 2.
x = 47.
Proof:
180 = x + (180 - 107) + (x + 13)
180 = 47 + (180 - 107) + (47 + 13)
180 = 47 + 73 + 60
180 = 120 + 60
180 = 180

Trisha's favourite song is 2 1/2 minutes. There is a drum solo that begins one third of the way into the song and last for 24 seconds. How many seconds does the drum solo end
Answer:
74 seconds or1 minute 14 secondsStep-by-step explanation:
The drum solo begins a third of the way into the song which lasts 2.5 minutes.
The drum solo therefore starts at:
= 2.5 * 1/3
= 0.83 minutes
Translate that to seconds by multiplying by 60:
= 0.83 * 60
= 50 seconds
Solo begins at 50 seconds in and lasts for 24 seconds:
= 50 + 24
= 74 seconds or
= 1 minute 14 seconds

Solve this equation by using the quadratic formula:
Answer:
x=(7+√29)/2 and x=(7-√29)/2
Step-by-step explanation:
x²-7x+5=0
x=[-b±√(b²-4ac)]/2a
x=[-(-7)±√(-7)²-4(1)(5)]/2(1)
x=[7±√(49-20)]/2
x=(7±√29)/2
Therefore, x=(7+√29)/2 and x=(7-√29)/2
You invested $100 at 8.2% which is compounded annually for 7 years. How much will your $100 be worth in 7 years?
Answer:
57.4%
Step-by-step explanation:
8.2 × 7 = 57.4
hope this helps!!
The formula for the amount earned with compound interest after n years is given as:
A = P [tex](1 + R/n)^{nt}[/tex]
P = principal
R = rate
t = time in years
n = number of times compounded in a year.
The $100 will be worth $174 after 7 years.
What is compound interest?It is the interest we earned on the interest.
The formula for the amount earned with compound interest after n years is given as:
A = P [tex](1 + R/n)^{nt}[/tex]
P = principal
R = rate
t = time in years
n = number of times compounded in a year.
We have,
P = $100
R = 8.2%
t = 7 years
n = 1 (compounded annually)
Now,
Amount:
A = P [tex](1 + R/n)^{nt}[/tex]
A = 100 [tex](1 + 0.082)^7[/tex]
A = 100 x [tex]1.082^7[/tex]
A = 100 x 1.7361643145023
A = $174
Thus,
The $100 will be worth $174 after 7 years.

What is the volume of a spherical shell with inner radius 7 and outer radius 8?
Answer:
707.9 cm³
Step-by-step explanation:
What is the volume of a spherical shell with inner radius 7 and outer radius 8?
The formula for the volume of a sphere is given as;
= 4/3 × π × r³
From the above question:
inner radius 7 and outer radius 8
Hence, the volume of a sphere with
inner radius 7 and outer radius 8 is calculated as:
V = (4/3 × π × 8³ ) - (4/3 × π × 7³)
V = 4/3 × π ×(8³- 7³)
V = 4/3 × π × (512 - 343)
V = 4/3 × π × 169
V = 707.9055446 cm³
V = 707.9 cm³
