Answer:
incremental area
Step-by-step explanation:
Let width be representd by 'W'
Original Area = W × X
Original Area = WX
New width= W+10
New Area= X(W+10)
= WX + 10X
= Original Area + 10X
Here 10X is the incremental area

Answer:
11.3
Step-by-step explanation:
i used the theorem of Pythagoras
Answer:
11.3
Step-by-step explanation:
In a right angled triangle: the square of the hypotenuse is equal to
the sum of the squares of the other two sides.
[tex]8^{2} + 8^{2} = x^{2}[/tex] (x is the hypotenuse)
64 + 64 = [tex]x^{2}[/tex]
[tex]x^{2}[/tex] = 128
=> x = [tex]\sqrt{128}[/tex] = 11.3137085 = 11.3
The loudness, L. measured in decibels (Db), of a sound intensity, I, measured in watts per square meter, is defined as
L - 10log , where lo - 10- and is the least intense sound a human ear can hear. Jessica is listening to soft music at a
sound intensity level of 109 on her computer while she does her homework. Braylee is completing her homework while
listening to very loud music at a sound intensity level of 10 on her headphones. How many times louder is Braylee's music
than Jessica's?
Answer:
Option A is correct.
Braylee's music is 3 times louder than Jessica's.
Step-by-step explanation:
Full Complete Questions
The loudness, L, measured in decibels (Db), of a sound intensity, I, measured in watts per square meter, is defined as
L = 10log (I/I₀), where lo = 10⁻¹² W/m²
and is the least intense sound a human ear can hear.
Jessica is listening to soft music at a sound intensity level of 10⁻⁹ W/m² on her computer while she does her homework.
Braylee is completing her homework while listening to very loud music at a sound intensity level of 10⁻³ W/m² on her headphones. How many times louder is Braylee’s music than Jessica’s?
times louder
3 times louder
30 times louder
90 times louder
Solution
The loudness of a sound intensity is given as
L = 10 log (I/I₀)
For Jessica
I = 10⁻⁹ W/m²
I₀ = 10⁻¹² W/m²
L = 10 log (10⁻⁹/10⁻¹²)
L = 10 log (10³)
L = 10 × 3 = 30 dB
For Braylee
I = 10⁻³ W/m²
I₀ = 10⁻¹² W/m²
L = 10 log (10⁻³/10⁻¹²)
L = 10 log (10⁹)
L = 10 × 9 = 90 dB
How many times louder is Braylee's music than Jessica's?
The factor by which Braylee's music is louder than Jessica's = (90/30) = 3
Braylee's music is 3 times louder than Jessica's.
Hope this Helps!!!

Step-by-step explanation:
elijah's credit card statement showed these items: Last Balance Payments Finance Rate New Charges $152.58 $45.00 1.5% $213.40 What is Elijah's new balance? $320.98 $322.59 $323.27 $397.51
Answer:
Option A,$320.98 is correct
Step-by-step explanation:
The new balance on Elijah's credit is the sum of the last balance plus new charges minus payments made.
last balance as shown by the statement was $152.58
new charges were $213.40
payment made by Elijah was $45
new balance=$152.58+$213.40-$45=$320.98
The rationale for this is that the new charges on the card account add to previous balance owed by Elijah while the payment of $45 made reduces overall balance.
Answer:
Other answer is incorrect. Elijah's new balance would be $322.59

|x+5|=3. Find all possible values for x (There are 2 possible values)
Answer:
x=-2 and x=-8
Step-by-step explanation:
(x+5)=3
Subtract 5 from both sides, to isolate x
x=-2
-(x+5)=3
Distribute the -
-x-5=3
Add 5 to both sides to isolate x
-x=8
Multiply both sides by -
x=-8

Jaira is having pizza for her birthday party. She can make two small pizzas, each with a radius of 6 inches, or one large pizza with a radius of 12 inches. Which option will give her more square inches of pizza?
Answer: One large pizza with a radius of 12 inches
Step-by-step explanation:
Hi, to answer this question we have to calculate the area of each option.
Area of a circle: π r^2
Option 1: two small pizzas, each with a radius of 6 inches.A = π r^2 = π 6^2 = 113.1 in2
Since there are 2 small pizzas we have to multiply the area by 2:
113.2 x 2 = 226.2 in2
Option2 = one large pizza with a radius of 12 inchesA = π r^2 = π 12^2 = 452.38 in2
Since 452.38 in2 > 113.1 in2
Option 2 (one large pizza) will give her more square inches of pizza

A bag contains 3 red, 4 blue, and 6 yellow marbles. One marble is selected at a time, and once a marble is selected, it is replaced. Find each probability. P(red and yellow)
Answer:
red = 3/13
yellow = 6/13
blue= 4/13
Step-by-step explanation:
breainliest really needed!!
The probability of selecting the red marble and yellow marble is 18/169.
What is the probability?Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.
We know that, probability of an event = Number of favourable outcomes/Total number of outcomes.
Given that, a bag contains 3 red, 4 blue, and 6 yellow marbles.
Total number of outcomes = 3+4+6=13
Probability of selecting red marble = 3/13
Probability of selecting yellow marble = 6/13
So, P(red and yellow) = 3/13 × 6/13
= 18/169
Therefore, the probability of selecting the red marble and yellow marble is 18/169.

Show the Euler-Descartes formula holds for the Great Pyramid of Cheops
Answer:
For the great pyramid of Cheops, V + F = E + 2 gives 5 + 5 = 8 + 2 which proves Euler-Descartes formula
Step-by-step explanation:
The great pyramid of Cheops is a square based pyramid therefore we have;
V + F = E + 2
Where:
V = Vertices
F = Faces
E = Edges
Hence, we have for a square pyramid;
V = 5 vertices (One at the peak, and four at the base edges)
F = 5 faces (The four lateral or side faces and the base)
E = 8 edges ( The four lateral edges and the four base edges)
Hence;
5 + 5 = 8 + 2 which proves Euler-Descartes formula.
