Answer:
Check below :)
Step-by-step explanation:
If you are asked to find a side of a triangle using a given side and an angle. You should check if it is a right-angled triangle, if it is then you can use the SOH, CAH, TOA which uses the formulae as shown:
sinΘ= [tex]\frac{opposite}{hypotenuse}[/tex]
cosΘ= [tex]\frac{adjacent}{hypotenuse}[/tex]
tanΘ= [tex]\frac{opposite}{adjacent}[/tex]
(Search them online for detailed explanation about trigonometry on right-angled triangles)
If it is not right-angled triangles, you need to double-check if there is another side given or angle given to use the sine rule or cosine rule
Sine rule: 2 angles and opposite side/ 2 sides and opposite angle
Cosine rule: involves 3 sides and one angle
The 2 pentagons above are similar. What is the area of the smaller pentagon?
Answer:
16^2
Step-by-step explanation:
All you have to do is do 64 *.25 and you get 16
The area of the smaller pentagon is 4 in². thus option B is correct.
How to determine the area of the smaller pentagon?The ratio of the side lengths are given:
Small : Large = 3.5 : 14
The area of the larger pentagon is given;
Area = 64 in²
By Using the given parameters, the area of the small pentagon:
Area = (Small/Large)² * Area of Large
Area = (3.5/14)² * 64
Area = 4
Hence, the area of the smaller pentagon is 4 in². thus option B is correct.

1. Edna bought an RTW dress for Php575.00 at 20% discount. What was
the original price?
Answer:
i think original price Php656.25
Step-by-step explanation:
original price Php x
80%x = 575
x = 575×100/80
x = 656.25
original price Php656.25
Please solve this...I can;t do it do it
Answer:
Area = 867 meters
Step-by-step explanation:
You have a rectangle. This means opposite sides are equal. If you set these expressions equal to each other, you will get two equations with two unknowns, x and y. Next, solve the system of equations to find x and y. Then, use the values to find the length and width of the rectangle. Last, multiply length × width to find the area.
A bacterial population has an exponential growth rate of 11.2% per hour. If there were 480 bacteria initially, what would the bacterial population be after 5 hours
The number of bacterial population after 5 hours is; 816
The formula for the exponential growth of the population is;N(t) = N_o(1 + r)^(t)
Where;
N(t) is number of bacteria after t hours
N_o is number of bacteria initially
r is growth rate
t is time
We are given;N_o = 480
r = 11.2% = 0.112
t = 5
Thus;N(5) = 480(1 + 0.112)^(5)
N(5) = 816.14
Approximating to a whole number gives; N(5) = 816 bacteriaRead more about exponential growth at; https://brainly.com/question/15316908
Which equation represents the line that passes through the points (0, 3) and (2,6)
A y = -3/2x + 3
B y = 2/3x + 3
C y = 3/2x + 3
D y = 3/2x
Answer:
C) y=3/2x+3
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(6-3)/(2-0)
m=3/2
y-y1=m(x-x1)
y-3=3/2(x-0)
y=3/2(x)+3
y=3/2x+3
Answer:
C) y=3/2x+3
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(6-3)/(2-0)
m=3/2
y-y1=m(x-x1)
y-3=3/2(x-0)
y=3/2(x)+3
y=3/2x+3
Given the Data Points : (9, 72) (4, 32) (7, 56) What is the constant of variation?
The constant of variation of the data point is 8.
An equation is an expression that shows the relationship between two or more variables and numbers.
If two variables are proportional, they can be represented by:
y ∝ x
y = kx
k is the constant of variation.
For the point (9, 72):
72 = 9k
k = 8
For the point (4, 32):
32 = 4k
k = 8
For the point (7, 56):
56 = 7k
k = 8
The constant of variation of the data point is 8.

A 12 ounce Starbucks latte costs $3.36. What is the constant of proportionality that relates the cost in dollars, y, to the number of ounces, x, in a Starbucks latte?
Answer:
Y = X times 0.28
Step-by-step explanation:
1. You set it up as a proportionality
12/1 and 3.36/x
The x stands for how much money it takes to get 1 ounce
2. You do the old man line.
12 times x = 3.36 times 1
12x = 3.36
3. Now you divide 3.36 by 12
3.36 divided by 12
.28
4. You insert 0.28 into the problem
12 times 0.28 = 3.36
X = 0.28
So 1 ounce costs $0.28
So Y = X times 0.28

I have used a graph to estimate these answers. See image. If you are learning how to find the line of best fit for a data set, you might be expected to do those calculations, depending on the level of your math class. Many upper level math classes would use technology to find a line of best fit.
See image to see the data set given on an xy-axis in red. The circled areas are where the estimated numbers would lie, where
x = -3 (in blue) and where
y = -20 (in green)
The directions say estimate, so a graph is a good justification for several answers in the general area.

Answer:
The first graph is correct.
Step-by-step explanation:
Note that the equation states x ≥ 2. It includes the "equals" sign, so the graph line should include 2. This is indicated by the solid line, as opposed to the 4th graph, which shows it as a dashed line. The dashed line is correct for x>2, but not for x ≥ 2.

Answer:
h⁰ = 84⁰
f⁰ = 132⁰
g⁰ = 28⁰
Step-by-step explanation:
As we know that sum of all the angles in a triangle is 180⁰, so,
h⁰ + 48⁰ + 48⁰ = 180⁰
h⁰ = 84⁰
Now, we can find f⁰ by Linear Pair theorem, which states that the angles sum will equal to 180⁰.
48⁰ + f⁰ = 180⁰
f⁰ = 132⁰
Again, g⁰ can be founded the same way as h⁰.
20⁰ + 132⁰ + g⁰ = 180⁰
g⁰ = 28⁰

High school
math/ geometry
Answer:
Well a triangle itself is worth 180 degrees (Inteirior angles)
your given “a” “b” and you need to find c.
So you can subtract
A is 50
B is 55
So
<BCA= 180- 55-50
Is the answer (b)
Answer:
B
Step-by-step explanation:
A triangle's angles all add up to 180 degrees. If m∠A is 50 and m∠B is 55 then m∠C is 75.
m∠C = 180 - (m∠A - m∠B); which is 180 - 105
180 - 105 is 75; Therefore, m∠C is 75 degrees
Proof: 50 + 55 + 75 = 180
Pam works a 52 hours in a week. Considering that a normal work week is 40 hours and paid at $1470 per hour and overtime is paid at time and a quarter
What is her basic wage ?
How much is she paid in overtime wages? (SHOW WORK) *
What is her gross wage ?
Step-by-step explanation:
they way it is written, she has one of the best paying jobs in the world : $1470 per hour ...
but I guess it is really $14.70 per hour, right ?
that is then her basic wage : $14.70 per hour for 40 hours = 14.7 × 40 = $588.
her overtime rate is then 14.7×1.25 (one time and a quarter) = 18.375 ≈ $18.38
and she gets that rate for all hours beyond the basic 40 hours, so, 52-40 = 12 hours.
12×18.38 = $220.56
or if you need it totally precise
12×18.375 = $220.50
in total, her gross wage for that week is then
588 + 220.56 = $808.56
or totally precise with unrounded hourly rates
588 + 220.5 = $808.50
which would create a mean hourly rate
808.56/52 = $15.54923077... per hour ≈ $15.55 per hour
or
808.5/52 = $15.54807692... per hour ≈ $15.55 per hour
many payroll systems do the rounding of the hourly rates and then calculate the total amount (as the first option here). some others keep the full decimal positions in the calculation and then only round the total (as the second option here).
so, it is the question what your teacher expects here. I cannot tell from the description.
