Explanation:
I recommend drawing out the triangle. See below.
Notice how each lowercase letter is a side length, and the uppercase letters are angles. Also, each lowercase letter is opposite their corresponding uppercase counterpart.
side a is opposite angle Aside b is opposite angle Bside c is opposite angle CWe're given that angles B and C are 22 degrees and 52 degrees in that order. Let's use the fact that the three angles of any triangle must add to 180 to solve for angle A
A+B+C = 180
A+22+52 = 180
A+74 = 180
A = 180-74
A = 106
We do this so we can then apply the law of sines
sin(A)/a = sin(B)/b
sin(106)/30 = sin(22)/b
b*sin(106) = 30*sin(22) ....... cross multiplication
b = 30*sin(22)/sin(106)
b = 11.6910908340182 ....... which is approximate
b = 11.7

suppose the function g(x) doubles the square of the input and then subtracts 13. what is g(3)?
Given:
The function [tex]g(x)[/tex] doubles the square of the input and then subtracts 13.
To find:
The value of [tex]g(3)[/tex].
Solution:
Let [tex]x[/tex] be the input value.
The square of the input is [tex]x^2[/tex].
Doubles the square of the input [tex]2x^2[/tex].
Doubles the square of the input and then subtracts 13, i.e., [tex]2x^2-13[/tex].
So, the function is:
[tex]g(x)=2x^2-13[/tex]
Putting [tex]x=3[/tex] in the above function, we get
[tex]g(3)=2(3)^2-13[/tex]
[tex]g(3)=2(9)-13[/tex]
[tex]g(3)=18-13[/tex]
[tex]g(3)=5[/tex]
Therefore, the value of [tex]g(3)[/tex] is 5.

If a change dispenser contains 32 coins consisting of
only dimes and quarters worth $5.15, how many
dimes are in the dispenser?
=================================================
Work Shown:
d = number of dimes
q = 32-d = number of quarters
$5.15 = 515 cents
10d+25q = 515
10d+25(32-d) = 515
10d+800-25d = 515
-15d+800 = 515
-15d = 515-800
-15d = -285
d = -285/(-15)
d = 19
There are 19 dimes. You can stop here if you want.
q = 32-d = 32-19 = 13
There are 13 quarters
-------------------------------
Check:
1 dime = 10 cents
19 dimes = 19*10 = 190 cents
1 quarter = 25 cents
13 quarters = 13*25 = 325 cents
total value = 190 cents + 325 cents = 515 cents = $5.15
The answer is confirmed.

The circumference of a circle is 6π m. What is the area, in square meters? Express your answer in terms of
π
π.
Answer:
9π meters
Step-by-step explanation:
SInce 6π is the circumference of the circle, 6π would be the diameter.
We need to then convert 6π into the radius which we can do by dividing 6π by 2 to get 3π.
The formula for the area of a circle is πr^2. Plug in the previous result for the radius to get the following:
π3^2
9π
Answer:
Area=9π m²
Step-by-step explanation:
Hi there!
We are given that the circumference of a circle is 6π meters, and we want to find the area of the circle
The formula to find the circumference of a circle is 2πr, where r is the radius
The formula to find the area of a circle is πr², where r is the radius
So we need to find the radius
As 6π and 2πr both equal the circumference of the circle, 6π is equal to 2πr. This is possible by a property known as transitivity (if a=b and b=c, then a=c) .
As an equation, the result is:
6π=2πr
Divide both sides by 2π
3=r
So the radius is 3 meters
Now, substitute 3 as the radius in πr² to find the area
A=πr²
A=π(3)²
Raise 3 to the second power, which is the same as multiplying it by itself
A=π*9
A=9π m²
Hope this helps!

Solve for the radius using the pythagorean theorem:
a² + b² = c²
We know the lengths of the hypotenuse and one leg, so:
a = 12
b = ?
c = 16
Plug these into the equation:
12² + b² = 16²
Simplify:
144 + b² = 256
Subtract both sides by 144:
b² = 112
Take the square root:
b ≈ 10.6
Thus the radius is about 10.6 cm.

-72 + (-30) + 10 =
-72-30+10.
-72-30=-102
10-102 is also the same as
-102+10
The final answer is -92
Answer:
-92
Step-by-step explanation:
-72 + (-30) + 10 =
-72+ -30
Since they both have the same sign, add and then take the sign
72+30 = 102 and then take the negative sign
-102
-102+10
They have opposite signs, so we subtract and take the sign of the larger
102 -10 = 92
And 102 was negative so take the negative sign
-92

if 5 hockey balls and 3 sticks cost $230.00 and 5 balls and 2 sticks cost $200 how much does one hockey ball cost?
step by step explanation:
Answer:
$28.
Step-by-step explanation:
We have the system of equations
5b + 3s = 230 (b = cost of 1 ball and s = cost of 1 stick).
5b + 2s = 200
Subtract the above from the first equation:
s = 30
So, substituting in equation 1:-
5b + 3(30) = 230
5b = 230 - 3(30) = 140
b = 28.
Checking in equation 2:-
5(28) + 2(30)
= 10 + 60
= 200.
- this checks out OK.
The cost of one hockey ball will be $28.
What is an expression?Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
The system of equations from the given data are:-
5b + 3s = 230 (b = cost of 1 ball and s = cost of 1 stick).
5b + 2s = 200
Subtract the above from the first equation:
s = 30
So, substituting in equation 1:-
5b + 3(30) = 230
5b = 230 - 3(30) = 140
b = 28.
Therefore, the cost of one hockey ball will be $28.

Tommy types 54 words per minute, with an average of 3 mistakes. How many mistakes would you expect Tommy to make if he typed 300 words?
Answer:
around 17 mistakes
Step-by-step explanation:
We can write a ratio to solve
54 words 300 words
------------------ = -------------------
3 mistakes x mistakes
Using cross products
54x = 3*300
54x = 900
Divide by 54
54x/54 = 900/54
x =50/3
x = 16.66666666(repeating)
around 17 mistakes
X = mistakes in 300 words
54/3 = 300/X
54X = 3 x 300
X = 900/ 54
X = about 17 words, since 16 and 2/3 rounded to the nearest tenth is 17

a) Complete the scale drawing.
1.5m
Not drawn accurately
b) Can Susie stand up in the
middle of the tent?
1.5m
Scale: 1 cm represents 60 cm
Split the triangle into 2 right in the middle so you have 2 identical right triangles. The base on one would be half the base of the triangle shown so, the base would be: 1.5/2 = 0.75 m.
Now using the Pythagorean theorem you can find the height:
Height - sqrt(1.2^2 - 0.75^2)
Height = sqrt(1.44 - 0.5625)
Height = sqrt(0.8775)
Height = 0.93675 meters
The height of the tent is smaller than the height of Suzie so she cannot stand up.
