The triangle with sides 9 , 12 and 14 is an acute triangle
What is a Triangle?
A triangle is a plane figure or polygon with three sides and three angles.
A Triangle has three vertices and the sum of the interior angles add up to 180°
Let the Triangle be ΔABC , such that
∠A + ∠B + ∠C = 180°
For a right angle triangle
From the Pythagoras Theorem , The hypotenuse² = base² + height²
Given data ,
Let the Triangle be ΔABC
Let the three sides of the Triangle be
First side = AB
Second side = BC
Third side = CA
Now , the three sides are having lengths as
AB = 9
BC = 12
CA = 14
Now , from the Pythagoras Theorem ,
If , base² + height² = hypotenuse² , it is a right angled triangle
If , base² + height² > hypotenuse² , it is a acute angled triangle
If , base² + height² < hypotenuse² , it is a obtuse angled triangle
So , substituting the values , we get
AB² + BC² > AC²
So ,
9² + 12² > 14²
81 + 144 > 196
225 > 196
Therefore , the triangle ABC is an acute angled triangle
Hence , The triangle with sides 9 , 12 and 14 is an acute triangle

Find the area of a right triangle with a height of 8 1/2 feet and a base of 15 feet
Answer:
63.75
Step-by-step explanation:
The equation for finding the area of a triangle is 1/2b x h
b = base
h = height
b = 15
h = 8.5
15(1/2) x 8.5
7.5 x 8.5 = 63.75
Answer:
A = 63.75 ft^2, or 63 3/4 ft^2
Step-by-step explanation:
The formula for the area of a triangle of base b and height h is
A = (1/2)(b)(h).
With h = 8.5 ft and b = 15 ft, the area of the triangle in question is
A = (1/2)(8.5)(15)ft^2, or
A = 63.75 ft^2, or 63 3/4 ft^2

Answer:
43
Step-by-step explanation:
180-123=57
180-(57+80)=43
Answer:
x=43
Step-by-step explanation:
the other two angles measure 80 (vertical angles are equal) and 57, (straight lines make 180 degree angles)
so x = 43 because 180-(80+57)=43 (180 degrees in a triangle)

What are simple and compound interests?Simple interest is often a predetermined percentage of the principle amount borrowed or lent paid or received over a specific time period.
Borrowers are required to pay interest on interest in addition to principal since compound interest accrues and is added to the accrued interest from prior periods.
The formula for simple interest is SI = (p×r×t)/100 and the formula for compound interest is A = P(1 + r/100)ⁿ.
∴ P + (p×r×t)/100 + P(1 + r/100)ⁿ is the total amount after 2 years.
= 450 + (450×4.5×2)/100 + 350(1 + 4.25/100)².
= 450 + 40.5 + 350(1.0425)².
= 490.5 + 380.38.
= $870.88.

At the youth center, the committee has decided to create a circular shaped flower bed. They plan to cover the flower bed with mulch. A flower bed with a 12' diameter will cost $150 to cover with mulch. A flower bed with an 18' diameter will cost $300 to cover. Which is the better value?
Answer:
12 in diameter bed will give better value
Step-by-step explanation:
Given:
Cost of cover 12 in diameter bed = $150
Cost of cover 18 in diameter bed = $300
Find:
Better value
Computation:
Area of bed = πr²
Area of 12 diameter of bed = (22/7)(6)²
Area of 12 diameter of bed = 113.14 in²
Area of 18 diameter of bed = (22/7)(9)²
Area of 18 diameter of bed = 113.14 in²
Area of 18 diameter of bed = 254.57 in²
Compare cost of bed 1 = 113.14 / 150 = 0.75 in per dollar
Compare cost of bed 2 = 254.57 / 300 = 0.84 in per dollar
So,
12 in diameter bed will give better value

What is an arithmetic sequence?A series of integers called an arithmetic succession or arithmetic chain of events has a fixed difference between the terms.
Let a₁ be the first term and d be a common difference.
Then the nth term of the arithmetic sequence is given as,

The arithmetic sequence is given below.
3/8, 3/4, 1 ¹/₈, 3/2, 1 ⁷/₈, ......

The first term of the arithmetic sequence is 3/8. And the common difference of the arithmetic sequence will be given as,
d = 3/4 - 3/8
d = 6/8 - 3/8
d = (6 - 3)/8
d = 3 / 8

Maritza worked at an ice cream parlor selling milkshakes and ice cream cones. Altogether, she sold 149 milkshakes and ice cream cones. The milkshakes sold for $4 and the ice cream cones for $3. The total amount collected was $533. How many milkshakes and ice cream were sold?
Answer:
86 milkshakes and 63 ice cream were sold
Step-by-step explanation:
Let the amount of milkshake sold be x
Let the amount of ice cream sold be y
If she sold 149 milkshakes and ice cream cones then;
x+y = 149 ... 1
If the milkshakes sold for $4 and the ice cream cones for $3, with total amount #533 collected then;
4x + 3y = 533 ....2
Solve both equations simultaneously
x+y = 149 ... 1 * 4
4x + 3y = 533 ....2 * 1
________________________
4x+4y = 596
4x+3y = 533
Subtract
4y-3y = 596-533
y = 63
since x +y = 149
x+63 = 149
x = 149 - 63
x = 86
Hence 86 milkshakes and 63 ice cream were sold
