PLs, help me with this math question, and please answer if you only know it.
Answer:
Step-by-step explanation:
This is quite a doozy, so try and follow along. If you don't know your circle stuff well, it will be more difficult for you to understand how all this comes together.
First, we were given that angle CBD = 55. That means that angle CED is also 55 since they are both inscribed angles and they both intercept the same arc, arc CD. Angle BFC is congruent to angle 5 because they are vertical and vertical angles are congruent, so that means that triangle BFC is congruent to triangle EFD because of Angle-Angle-Side. Now that we got that out of the way, let's move on. We will come back to that in a bit.
Angle 1 intercepts arc BE and since angle 1 is an inscribed angle, it is half the measure of its intercepted arc. Therefore,
∠1 = 25° ; angle BCE also equals 25 degrees since they are both inscribed and they both intercept the same arc (again, arc BE).
If angle BCE is 25, and angle CBD is 55, then angle F, by the Triangle Angle Sum Theorem, must equal 180 - 25 - 55 = 100. And if Angle F = 100, then
∠5 = 100° . Angles 4 and 5 are supplementary, therefore,
∠4 = 80°
Since angle CBD was given as 55 and is an inscribed angle for arc CD, then arc CD is twice the measure of its inscribed angle and arc CD is 110 degrees. Angle 6, then, is one-half the difference of arc CD and arc BE so
∠6 = 30°
Angles 2 and 3 are congruent since they are both inscribed and they both intercept the same arc (arc DE); and since triangles BFC and EFD are congruent, by CPCTC, sides BF and EF are congruent...which means by the IsoscelesTriangle Theorem, angle 2 and angle BEC are congruent. 180 - 80 = 100 and divide that in half to get that
∠2 ≅ ∠3 = 50°
Lastly, angle 7 is half the measure of its intercepted arc (arc BE, given as 50), therefore,
∠7 = 25°

Last year, ginger cost $15 per kilogram. Due to a harvest shortage this year, the price of ginger has to increase by 15% per kilogram. Find the cost of ginger per kilogram this year.
=======================================================
Explanation:
15% of 15 = 0.15*15 = 2.25
The cost has increased by $2.25 which means the cost per kilogram is now 15+2.25 = 17.25 dollars
------------
As a slight shortcut, we can multiply the old cost (15) by the multiplier 1.15 to get the same result:
1.15*15 = 17.25
This method allows us to chain together many percentage increases, and it also allows us to include percentage decreases as well. Note how 1.15 is basically the result of 100% + 15% = 1.00+0.15 = 1.15

Answer:
484 cm³
Step-by-step explanation:
The formula for the volume of a pyramid is ...
V = 1/3Bh
where B is the base area and h is the height.
Here, the base is a square 11 cm on a side, so its area is ...
B = s² = (11 cm)² = 121 cm²
Then the volume of the pyramid is ...
V = 1/3(121 cm²)(12 cm) = 484 cm³
Which pair of angles has congruent values for the sin x° and the cos y°?
A) 42°, 138°
B) 42°, 48°
C) 42°,132°
D) 42°, 42°
Answer:
B: 42°, 48°
Step-by-step explanation:
I took the test.
The pair of angles have congruent values for the sin x° and the cos y° is 42; 48.
What are congruent angles?Angles that are of the same measurement are called congruent.
Suppose that two angles ∠A and ∠B are of the same measure,
then
[tex]m\angle A = m\angle B[/tex]
is the notation to say that they are of the same measurement, where the small m shows that its the measurement of the angles they're preceding.
We write the congruency between them as;
[tex]\angle A \cong \angle B[/tex]
Congruent angles can be defined as a type of angle that is known to have all sides in equal measure.
sin x = cos (90-x)
therefore, sin 42 = cos(90-42)
= cos 48
Hence, option B) 42°, 48° is correct

Your house had a value of $480,000 and increased in value by 3.5%. How much is your house
worth now?
Answer:
$496800
Step-by-step explanation:
You need to find 3.5% of 480,000 and then add it to 480000:
You convert 3.5% to 0.035 (divided by 100).
Now you multiply 0.035 * $480,000 = $16800 (this is the amount of money to add to the value of the house)
Total value of the house: $480,000 + $16,800 = $496800

V = ( 4/3 ) × π × ( 3 )^3
V = ( 4/3 ) × 3 × 9 × π
V = 4 × 9 × π
V = 36 π m^3

Solve the following question
Answer: It's C f"(x)= 15x^2+235 Hope that helps!
Step-by-step explanation:
Find the Greatest Common Factor (GCF).
GCF = 5
2. Factor out the GCF. (Write the GCF first. Then, in parentheses, divide each term by the GCF.)
5(15x^2/5+235/5)
3. Simplify each term in parentheses and that would give you 5(3x^2+47) and that's why I think it C but i'm not so sure but if you get it right can you please make me Brainliest bye and I hope you get it right!

Answer:
40 daps
Step-by-step explanation:

Chris went out to dinner. His total bill before tax and tip was $23.40. He was charged an additional 8% tax and he also paid 15% tip on the original bill
Answer:
total cost = amount paid + tax paid + tip
total cost = $23.40 + 1.872 + $3.51
Step-by-step explanation:
Chris went out to dinner. His total bill before tax and tip was $23.40 He was charged an additional 8% tax and he also paid 15% tip on the original bill. Write an expression that will show the total cost including tax and tip.
total cost = amount paid + tax paid + tip
tax paid = 8% x $23.40
0.08 x $23.40 = $1.872
tip = 15% x original bill
0.15 x $23.40 = $3.51
total cost = $23.40 + 1.872 + $3.51
