A TV that normally sells for $900 is on sale for 45% off. What is the sale price?
Answer:
$495
Step-by-step explanation:
(900 ÷ 100) × 45
= 405
900 - 405
= 495
determine the level in decibels of a sound that has an intensity I = 10^-6 watts/cm2
Answer:
The level in decibels is 100.
Step-by-step explanation:
The intensity level in decibels (β) can be found using the following equation:
[tex] \beta = 10log(\frac{I}{I_{0}}) [/tex]
Where:
I: is the intensity = 10⁻⁶ W/cm²
I₀: is the reference intensity = 10⁻¹² W/m²
First, we need to convert the unit of the given intensity from W/cm² to W/m².
[tex] I = 10^{-6} \frac{W}{cm^{2}}*\frac{(100 cm)^{2}}{1 m^{2}} = 10^{-2} W/m^{2} [/tex]
Hence, the level in decibels is:
[tex] \beta = 10log(\frac{10 ^{-2} W/m^{2}}{10^{-12} W/m^{2}}) = 100 dB [/tex]
Therefore, the level in decibels is 100.
I hope it helps you!
Triangle congruence geometry
Answer:
Not necessarily
Step-by-step explanation:
The triangles have two sides congruent to each other (BA and RA/BE). They also have angles BRA and BEA congruent, but these do not fit into any of the congruency theorems (SSS, SAS, ASA, or AAS).
A company is designing a new logo that is comprised of four identical sectors of circles that have central angles
that measure 30º. A portion of the logo is shaded. The distance from the center, C, to point A is 8 inches
and the distance from point A to point B is 3 inches.
Determine the area of the logo that is shaded to the nearest tenth of a
square inch. Show the work that leads to your answer.
============================================================
Explanation:
The radius of the larger circle is CB = CA+AB = 8+3 = 11 inches.
The area of the larger circle with this radius is...
A = pi*r^2
A = pi*11^2
A = 121pi
The area of the smaller circle (radius CA = 8 inches) is
A = pi*r^2
A = pi*8^2
A = 64pi
The difference is 121pi-64pi = 57pi
This represents the exact area of the full ring. Refer to figure 1 below. Specifically the red region of that figure.
However, we don't want the full ring. We only want a small fraction of it (as figure 2 shows, which is the original diagram your teacher gave you). Specifically, we want (4*30)/360 = 120/360 = 1/3 of the full ring. The 4*30 refers to the idea we have four copies of the 30 degree angle.
So we'll take 1/3 of the 57pi to get (1/3)*57pi = (57/3)pi = 19pi
-----------------------------------
The value 19pi is the exact area of the entire shaded region.
From here, you can use a calculator to determine that
19pi = 19*3.1415926535898 = 59.6902604182061 which rounds to 59.7
If your teacher insists you use pi = 3.14, then 19*pi = 19*3.14 = 59.66 which also rounds to 59.7

If f(x) = 7(x – 2) + 4(x + 1), what is f(2)?
Answer:
12
Step-by-step explanation:
f(x) = 7(x – 2) + 4(x + 1)
Let x =2
f(2) = 7(2 – 2) + 4(2 + 1)
=7(0) +4(3)
= 0+12
= 12

The trapezoid is enlarged by a scale factor of 3, what is the area of the scaled copy?
Answer:
Step-by-step explanation:
After enlargement,
Parallel sides are: 6*3 = 18 cm & 10*3 = 30cm
Altitude = 5 *3 = 15 cm
Area =[ (sum of the length of parallel sides)*height] ÷2
[tex]= \frac{(18+30)*15}{2}\\= \frac{48*15}{2}\\\\= 24 *15\\\\= 360[/tex]
Answer:
360 cm²
Step-by-step explanation:
The area (A) of the trapezoid is calculated as
A = [tex]\frac{1}{2}[/tex] h (b₁ + b₂ )
where h is the perpendicular height and b₁, b₂ are the parallel bases
Here h = 5 , b₁ = 10, b₂ = 6 , then
A = [tex]\frac{1}{2}[/tex] × 5 × (10 + 6) = 2.5 × 16 = 40 cm²
Enlarging by a scale factor of 3 means the area is increased by a factor
3² = 9
area of scaled copy = 9 × 40 cm² = 360 cm²
The first term of a geometric sequence is 6 and the fourth term is 384. What is the sum of the first 10 terms of the corresponding series?
Answer:
2097150
Step-by-step explanation:
GIVEN :-
First term of G.P. = 6Forth term of G.P. = 384TO FIND :-
Sum of first 10 terms of the G.P.CONCEPT TO BE USED IN THIS QUESTION :-
Geometric Progression :-
It's a sequence in which the successive terms have same ratio.General form of a G.P. ⇒ a , ar , ar² , ar³ , ....... [where a = first term ; r = common ratio between successive terms]Sum of 'n' terms of a G.P. ⇒ [tex]\frac{a(r^n - 1)}{r-1}[/tex].[NOTE :- [tex]\frac{a(1-r^n)}{1-r}[/tex] can also be the formula for "Sum of n terms of G.P." because if you put 'r' there (assuming r > 0) you'll get negative value in both the numerator & denominator from which the negative sign will get cancelled from the numerator & denominator. YOU'LL BE GETTING THE SAME VALUE FROM BOTH THE FORMULAES.]
SOLUTION :-
Let the first term of the G.P. given in the question be 'a' and the common ratio between successive terms be 'r'.
⇒ a = 6
It's given that forth term is 384. So from "General form of G.P." , it can be stated that :-
[tex]=> ar^3 = 384[/tex]
[tex]=> 6r^3 = 384[/tex]
Divide both the sides by 6.
[tex]=> \frac{6r^3}{6} = \frac{384}{6}[/tex]
[tex]=> r^3 = 64[/tex]
[tex]=> r = \sqrt[3]{64} = 4[/tex]
Sum of first 10 terms [tex]= \frac{6(4^{10}-1)}{4 - 1}[/tex]
[tex]= \frac{6(1048576 - 1)}{3}[/tex]
[tex]= 2 \times 1048575[/tex]
[tex]= 2097150[/tex]

Gió thổi trên mặt nước trong các đại dương chịu trách nhiệm cho dòng hải lưu. Tuy nhiên, dòng hải lưu trong đại dương không được hình thành bởi gió đơn thuần. Nước gần cực lạnh trong khi nước gần xích đạo ấm. Sự chênh lệch nhiệt độ giữa hai vùng nước này cũng chịu trách nhiệm cho sự hình thành dòng hải lưu. Địa hình đáy đại dương, mưa và thậm chí thủy triều cũng gây ra dòng chảy trong nước.

A pen
Given :
Oye bought a pen for Rs 220 .
He sell the pen for Rs 250 .
To Find :
The profit Oye earned on the pen.
Solution :
We know, profit can we calculated as :
P = Cost Price - Selling price
P = Rs 250 - 220
P = Rs 30
Therefore, the profit amount on the pen is Rs 30 .

A chair rental company charges $100 for delivery plus $3 per chair.
Write an explicit function for the total cost, T(c), of renting c number of
chairs.
Answer:
T(c) = 100 + 3*c
Step-by-step explanation:
cost = fee + cost per chair * number of chairs
T(c) = 100 + 3*c
Answer:
T ( c)= $ 100 + $ 3 c
Step-by-step explanation:
Given that :-
Fee for delivery = $ 100Cost per chair = $ 3No. of chair = cTo Find :-
Total cost T( c) of renting c no. of chairs.Solution :-
Total Cost, T ( c) = Fee + cost per chair × no. of chairs.
T ( c) = $ 100 + $ 3 × c
T ( c) = $ 100 + $ 3 c

Find the first, fourth, and eighth terms of the sequence
A(n) = −2 ∙ 2x − 1
Answer:
1st term = -5
4th term = -17
8th term = -33
Step-by-step explanation:
1st term = -2 x (2 x 1) -1
= -2 x 2 - 1
= -4 - 1 = - 5
4th term = -2 x (2 x 2) -1
= -2 x 4 - 1
= -8 - 1 = - 9
8th term = -2 x (2 x 8) - 1
= -2 x 16 - 1
= -32 - 1 = - 33
