Based on the diagram, which expresses all possible lengths of segment AB?
AB = 25
27 81
Answers
Answer:B
Step-by-step explanation:
27 < AB < 81 expresses all possible lengths of segment AB
What is Inequality?A relationship between two expressions or values that are not equal to each other is called 'inequality.
The sum of the lengths of any two sides of a triangle is greater than the length of the third side (Triangle Inequality Theorem)
So AC+BC>AB
27+54>AB
81>AB
AB<81
27+AB>54
AB>54-27
AB>27
54+AB>27
AB>-27
Hence, 27 < AB < 81 expresses all possible lengths of segment AB

Alex and Freddy collect stamps. The number of stamps in Alex’s collection is in ratio 3:5 to the number of stamps in Freddy’s collection. If Freddy gives Alex 10 stamps, the ratio will change to 7:9. How many stamps are in both collections together?
Answers
the new ratio is 7 to 9, so we have the equation: (3x+10)/(5x-10)=7/9
9(3x+10)=7(5x-10)
27x+90=35x-70
160=8x
x=20
So Alex has 3*20=60 stamps while Freddy has 5*20=100. Together they have 160

Using reflection concepts, it is found that the correct option is:

Step-by-step explanation:
Parallel lines have the same slope.
So if you can find the slope of the given line, you have the slope you want.
Change the line into the form
y=mx + c
The value of m
will be the slope of the line.
9x −4 = 5y ← to make the y term positive
y=9/5x − 4/5
m=9/5

Help find the measure of G please.
Answers
Answer:
G = (x+10) = 42 degrees
Step-by-step explanation:
G is equal to the angle across from it because of the lines being equal.
Then you plug in an equation to solve for all 180 degrees of a triangle 3x + x+10 + x+10 = 180
5x+20 = 180
5x=160
x=32
(32)+10 = 42
G = 42 degrees

A 15 meter long cylinder with a diameter of 7 meters has a square prism
with a base length of 4 meters hole going all the way through the center of
it as shown in the diagram (not to scale). Find the volume of the composite
shape rounding to the nearest cubic meter.
Answers
Answer:
The volume of the composite figure is approximately 337.27 m³
Step-by-step explanation:
The given parameters are;
The length of the cylinder, L = 15 meters
The diameter of the cylinder, D = 7 meters
The base length of the square prism, B = 4 meters
We note that the square diagonal of the square = √(4² + 4²) = 4·√2 ≈ 5.66 meters, fits in the cylinder
Therefore, we have;
The volume of the composite figure = The volume of the cylinder - The volume of the square prism
The volume of the cylinder = π/4 × D² × L = π/4 × 7² × 15 ≈ 577.27 m³
The volume of the square prism = B² × L = 4² × 15 = 240 m³
∴ The volume of the composite figure ≈ 577.27 m³ - 240 m³ ≈ 337.27 m³
The volume of the composite figure ≈ 337.27 m³.

Answer: it should be 5
Step-by-step explanation: if 3 3/4 divided into three parts its 1 1/4. If we add 3 3/4 and 1 1/4, then we have 5

What is an arithmetic operation?The four basic mathematical operations are the addition, subtraction, multiplication, and division of two or even more integers.
Among them is the examination of integers, particularly the order of actions, which is crucial for all other mathematical topics, including algebra, data organization, and geometry.
As per the given information in the question,
The temperature rise of the compound to 3 3/4° every 3/4 of an hour.
1 hour = 60 minutes then,
3/4 of an hour = 3/4 × 60 = 45 minutes.
(15/4)° rise in 45 minutes or,
3.75° rise in 45 minutes.
Let the rise in temperature in 1 hour will be x° then,
x = (3.75 × 60)/45
x = 5° per hour.

Trey deposits $8000 into an account that pays simple interest at a rate of 5% per year. How much interest will he be paid in the first 4 years
6
Answers
Answer:
1600
Step-by-step explanation:
You want to calculate the interest on $8000 at 5% interest per year after 4 year(s).
The formula we'll use for this is the simple interest formula, or:
Where:
P is the principal amount, $8000.00.
r is the interest rate, 5% per year, or in decimal form, 5/100=0.05.
t is the time involved, 4....year(s) time periods.
So, t is 4....year time periods.
To find the simple interest, we multiply 8000 × 0.05 × 4 to get that:
The interest is: $1600.00
Usually now, the interest is added onto the principal to figure some new amount after 4 year(s),
or 8000.00 + 1600.00 = 9600.00. For example:
If you borrowed the $8000.00, you would now owe $9600.00
If you loaned someone $8000.00, you would now be due $9600.00
If owned something, like a $8000.00 bond, it would be worth $9600.00 now.
