In triangle ABC, AB=5cm, AC = 10cm, and BC = 12 cm
Determine the size of the largest angle.
Answer:
The largest angle is <B.
Because, AC is the longest and largest side of ∆ABC. Therefore, the angle opposite the largest side is also the largest.
This is a property in geometry.

Step-by-step explanation:
When you go to do a repeating decimal, put whatever repeats over 9. For example lets say we want .49494949 repeating it would be 49/99
however in this case we want 4 to repeat so it would be 4/9.

Answer: B.pi/2
ABCD is a square
=> Δ ABD is a isosceles right triangle at A
using pythago theorem, we have:
AB² + AD² = BD²
=> 2AD² = 4
⇔ AD² = 2
⇒ AD = √2
through O, draw EF parallel to AD and BC
=> EF is diameter
because EF//AD => EF = AD = √2 (because circle O is inscribed the square ABCD)
=> the area of the circle is [tex]S=\frac{(\sqrt{2})^{2} }{4}.\pi =\frac{\pi }{2}[/tex]

A hemispherical bowl is made of brass has an inner diameter 35 cm. What is the inner surface area? URGENT
Answer:
The inner surface area is: 1923.25 cm²
Step-by-step explanation:
A hemispherical bowl is made of brass has an inner diameter of 35 cm.
i.e. d = 35 cm
As the radius is basically half of the diameter.
r = d/2
= 35/2
= 17.5 cm
The inner surface area of a hemispherical bowl = 2πr²
= 2(3.14)(17.5)²
=1923.25 cm²
Therefore, the inner surface area is: 1923.25 cm²

Mr. Stack and Coach Pugh are racing down the highway. Coach Pugh is going five miles more an hour than twice Mr. Stack's speed. If Coach Pugh is going one hundred and five miles and hour, how fast is Mr. Stack going?
Answer:
50
Step-by-step explanation:
2(Mr stack's speed) = Coach Pugh's speed - 5mph
Mr stack's speed = (105mph - 5mph)/2
Mr stack's speed = 100mph/2
Mr stack's speed = 50mph

A $270 suit is marked down by 10%. Find the sale price.
15 people working 5 hours per day can make 30 units of a product in 10 days. Assuming all other factors remain constant and people of the same efficiency are used to make the same products, in how many days can 10 people make 10 units of the product if each of them works 10 hours per day?
Answer:
I don't really understand it very well
It will take 10 people working 10 hours per day about 2.5 days to make 10 units of the product.
From the statement of the question; 15 people working 5 hours per day can make 30 units of a product in 10 days. Hence, the number of units that can be made in a day is;
Number of units per day = (15*5*10)/30
= 25 units/day
Now; if 10 people make 10 units, working 10 hours per day, it will take them x number of days.
x = (25*10)/10*10
x = 2.5 days

Answer:
Step-by-step explanation:
ABC have sides: 5, 7 and 10
5^2 + 7^2 = 25+47 = 72 < 10^2
so triangle ABC is obtuse
JKL has sides: 12, 35 and 37
12^2 + 35^2 = 144 + 1225 = 1369 = 37^2
so triangle JKL is right-angled
PQR has sides 12, 10 and 16
12^2 + 10^2 = 144 + 100 = 244 > 16^2
so triangle PQR is acute

Choose all that apply
A) 4, 5, 6
B) 5, 12, 13
C) 8, 15, 17
D) 10, 15, 20
Answer:
A and D
Step-by-step explanation:
One side-base right triangle and one angle-based right triangle.
symplify the expression 3⁴÷3⁹. Select all that apply.
Answer:
C and D
Step-by-step explanation:
When you divide exponents with the same base, you just subtract the exponents.
3^4 / 3^9
4-9 = -5
3^-5
That can be rewritten into 1/3^5 and 1/243.
The perimeter of a triangle is 43 inches. The second side is 4 times as long as the first side. The third side is 1 inch longer than the first side. What is the length of each side
Answer:
First side=7
Second side =28
Third side =8
explanation:
Perimeter of a triangle is the sum of the length of the sides of the triangle. Given that the perimeter of the triangle = 43 inches
Second side is 4 times the first side
Third side is 1 inch longer the first
Let's call the first side x
Then equation for the perimeter of the triangle is given by
x+4x+x+1=43
We solve for x
6x+1=43
6x=43-1
6x=42
x=42/6
x=7
Therefore the first side x=7, the second side is 4x= 4*7=28, third side= 1+x= 1+7=8
Write the ratio 12 to 18 as a fraction in simplest form.
x to y can be expressed as a fraction this way: x/y.
Let x = 12
Let y = 18
12/18
We can now reduce to lowest terms.
Dividing 12 and 18 by 6, we get 2/3 as the final answer.
The simplified fraction is 2/3. This means that the ratio of 12 to 18 can be expressed as 2/3. It indicates that for every 2 units of the first quantity (12), there are 3 units of the second quantity (18). Simplifying the fraction ensures that there are no common factors other than 1 between the numerator and the denominator, making it the simplest representation of the ratio.
To express the ratio 12 to 18 as a fraction in simplest form, we can divide both numbers by their greatest common divisor (GCD). The GCD of 12 and 18 is 6. By dividing both numbers by 6, we simplify the fraction to its simplest form:
12 ÷ 6 = 2
18 ÷ 6 = 3
Thus, the simplified fraction is 2/3. This means that the ratio of 12 to 18 can be expressed as 2/3. It indicates that for every 2 units of the first quantity (12), there are 3 units of the second quantity (18).

As soon as a new car is purchased and driven away from the dealership, it begins to lose its value, or depreciate. Alonso bought a 1994 Plymouth Neon for $9559. One year later, the value of the car was $8500. What was the percent of decrease of the value of the car?
P.S. This is a percent increase/decrrease
from: 9559
to: 8500
%/100 = differences of to and from/ from ( before the number )
( no negative difference, bigger number subtract smaller number)
Answer:
11%
Step-by-step explanation:
$9559-$8500=1059
1059/9559= .110786
.110786 x 100= 11.0786%
11.0786%= 11%

the velocity of a falling body varies directly as the time of flight if the velocity of the falling body at the end of two seconds is 64.4ft/s find the velocity at the end of 5 seconds
Answer:
Step-by-step explanation:
If the velocity of a falling body varies directly as the time of flight, this is expressed as;
v α t
v = kt
k = v/t
If at t = 2secs, v = 64.4ft/s
k = 64/2
k = 32 ft
To get the velocity at the end of 5 secs, we will say;
at t = 5secs v = ?
From the formula;
v = kt
v = 32(5)
v = 160ft/s
Hence the required velocity is 160ft/s
