Let measure of angle B be 18 degrees and BC = 9. Find the length of AC, BA and the measure of angle C. Round to 1 decimal place when needed. Show all of your work.
Answer:
m∠C = 72°
BA = 8.6
AC = 2.8
Step-by-step explanation:
We can start by finding the sum of all angles in a triangle to find angle C. The sum of all angles is 180°, so we can write the equation:
m∠A + m∠B + m∠C = 180°
And substitute what we have:
90° + 18° + m∠C = 180°
108° + m∠C = 180°
m∠C = 72°
In order to find the side BA, we can use trig functions. We are given the hypotenuse and we are looking for the side adjacent to ∠B. The trig function that relates the two is cosine. We can set up the equation as follows:
cos(∠B) = [tex]\frac{BA}{BC}[/tex]
cos(18°) = [tex]\frac{BA}{9}[/tex]
9 * cos(18°) = BA
BA ≈ 8.559508647
And when we round, we get:
BA = 8.6
In order to find the side AC, we can use trig functions. We are given the hypotenuse and we are looking for the side opposite to ∠B. The trig function that relates the two is sine. We can set up the equation as follows:
sin(∠B) = [tex]\frac{AC}{BC}[/tex]
sin(18°) = [tex]\frac{AC}{9}[/tex]
9 * sin(18°) = AC
AC ≈ 2.781152949
We can round this to:
AC = 2.8

Sample Answer:
Both prisms are equal in volume, with it being 30 in^3. Although the triangle prism has a length of twice as much, this is countered by the formula for a triangular prism which requires for it to be divided by 2, where this is not present within the formula for a rectangular prism.
Step-by-step explanation:
For this, just pretend that h=1 to make the math easier. So the rectangular prism has a cross section that is 6 by 5 inches, so that will be its L & W.
The triangular prism has a cross section that is a 12 inch base times a 5 inch interior height, this will give the triangle's length and height respectively In this case, h will be its width, making the Base of the triangle which is Length * Width. Think of it like flipping over this prism, making the side facing you and make it the bottom of the prism.
Now, with the formulas for volume of the prisms:
Rectangular: L * W * H
Triangle: (L*W * H) / 2
Then just plug in the numbers:
Rectangular Prism:
L * H * H
6 * 5 * 1
30 * 1
30
Triangle Prism:
(12 * 5 * 1) / 2
60 / 2
30
They are equal to each other.

Answer:
5/16 pounds
Step-by-step explanation:
The problem mentions that Audrey needs to cut a 5-pound block into 16 pieces. This means that each of the 16 pieces of cheese must weigh the same, thus we have to divide 5 pounds by 16 to divide the weight equally. Thus, all you need to do is divide 5 by 16, giving you 5/16. Therefore, your answer is that each block of cheese weighs 5/16 pounds.
Answer:
0.3125 pounds
Step-by-step explanation:
Each wedge of cheese weights 0.1325 pounds

There are 4 brown socks and 14 blue socks in a drawer. In the dark, Jason pulls out a sock and puts it on his right foot. Then he pulls
out another sock and puts it on his left foot.
What is the probability that Jason has two brown socks on his feet?
Answer:
2/51
Step-by-step explanation:
# of brown socks = 4
# of blue socks = 14
total # of socks = 18
The probability of pulling 1 brown sock = 4/18
If he were to pull one brown sock there would be 1 less sock in the total # of socks and 1 less in the # of brown socks
So after the first pull ( if it were to be a brown sock )
there would only be 3 brown socks and 17 total socks
So the probability of pulling a brown sock then would be 3/17
Finally we multiply the two probabilities to get the answer
4/18 * 3/17 = 2/51
Hence, the answer is 2/51

y=x+3
y=1/3x-5
solve and graph
Answer:
(-9, -12)
Step-by-step explanation:
Given the expressions
y=x+3
y=1/3x-5
Equating both expressions;
y = y
x + 3 = 1/3x - 5
x - 1/3x = -5 -3
2/3 x = -8
x/3 = -4
x = -12
Since
y = x+ 3
y = -12 + 3
x = -9
Hence the required solution is (-9, -12)

Answer:
38°
Step-by-step explanation:
The angles in a triangle always add up to 180 degrees.
Therefore, all the angles in the triangle given in the question add up to 180 degrees.
So, let's create an equation and solve for [tex]x[/tex]:
[tex]x+44 + 63 + 85 + x = 180[/tex]
Simplify:
[tex]2x + 192=180[/tex]
Solving for [tex]x[/tex] we get:
[tex]2x=-12\\x=-6[/tex]
Now, let's put the value of [tex]x[/tex] we got into the formula for angle A.
[tex]x+44=y[/tex]
[tex]-6+44=y=38[/tex]

An online furniture store sells chairs for $150 each and tables for $600 each. Every day, the store can ship a maximum of 18 pieces of furniture and must sell at least $5400 worth of chairs and tables. If x represents the number of tables sold and y represents the number of chairs sold, write and solve a system of inequalities graphically and determine one possible solution.
Answer:
13,500
Step-by-step explanation:
x + y = 750
750 x 18 = 13.500
The value of the number of tables will be 6 and the number of chairs will be 12.
How to form an equation?When trying to set up or construct a linear equation to fit a real-world application, identify the known quantities and use the unknown quantity as a variable.
In other words, an equation is a set of variables that are constrained through a situation or case.
From the question constraint of a maximum of 18 pieces of furniture
x + y =18
From the question constraint of at least $5400 worth of chairs and tables
600x + 150y ≥ 5400
By equation first, y = 18 - x put this into second
600x + 150(18 - x) ≥ 5400
450x ≥ 2700
x ≥ 6 hence there is need to sell at least 6 tables.
Put x =6 into x + y =18 then
y = 12 hence at least 12 chairs need to be sold.

write 7.5^{1.25} as a radical
Answer:
[tex]\sqrt[4]{7.5^{4} }[/tex]
Step-by-step explanation:
Using the rule of exponents/ radicals
[tex]a^{\frac{m}{n} }[/tex] ⇔ [tex]\sqrt[n]{a^{m} }[/tex]
Given
[tex]7.5^{1.25}[/tex]
= [tex]7.5^{\frac{5}{4} }[/tex]
= [tex]\sqrt[4]{7.5^{4} }[/tex]
[tex]\sqrt[4]{7.5^{5} }[/tex] is the radical for [tex]7.5^{1.25}[/tex].
What are exponent rules?Exponent rules, which are also known as the 'laws of exponents' or the 'properties of exponents' make the process of simplifying expressions involving exponents easier. These rules are helpful to simplify the expressions that have decimals, fractions, irrational numbers, and negative integers as their exponents.
Given
[tex]7.5^{1.25}[/tex]
We can write 1.25 is [tex]\frac{5}{4}[/tex]
[tex]7.5^{\frac{5}{4} }[/tex]
Using the rule of exponents/radicals
[tex]a^{\frac{m}{n} }[/tex] = [tex]\sqrt[n]{a^{m} }[/tex]
[tex]7.5^{\frac{5}{4} }[/tex] = [tex]\sqrt[4]{7.5^{5} }[/tex]
[tex]\sqrt[4]{7.5^{5} }[/tex] is the radical for [tex]7.5^{1.25}[/tex].

Elise is investing 10,000 in an account that earns 2.25% simple interest. How many years will it take to have a balance of 12,700 in her account, if she does not add or withdraw from the account?
Answer:
12 years
Step-by-step explanation:
The formula to solve the above question i.e to find the time is given as:
Equation:
t = (1/r)(A/P - 1)
Calculation:
First, converting R percent to r a decimal
r = R/100 = 2.25%/100 = 0.0225 per year,
then, solving our equation
t = (1/0.0225)((12700/10000) - 1) = 12
t = 12 years
Therefore, if she does not add or withdraw from the account, the time it
will take to have a balance of 12,700 in her account is 12 years

What value of x will make x1/4=3 true?
Answer:
okay so, x would be 12
Step-by-step explanation:
( if you ever see p5 (or any other variable) then that’s means you gotta multiply, so maybe imagine it like px5, p5 would just be a easier way.)
1. x times 1 divided by 4 is 3, a simpler way to put it!
x would be 12 since 12x1 is 12
2. We divide 12 by 4 which gives us a total of 3
