Answer:
FV= $712.88
Step-by-step explanation:
Giving the following information:
Initial investment (PV)= $500
Number of periods (n)= 12 years
Interest rate (i)= 3% compounded annually
To calculate the future value, we need to use the following formula:
FV= PV*(1+i)^n
FV= 500*(1.03^12)
FV= $712.88

If t= 9m,what is the area of the triangle
Help
Answer: the answer
we use the formula 1/2 .b .h
Step-by-step explanation:
the answer is 1,134, we substitute the t to 9 for each number, for example 4(9) 7(9)
4(9)= 36
7(9)=63
now we find the half of our bottom number which is 4=36
1/2 36= 18
so now we have 18x63=1,134
so our answer is 1,134
The area of the triangle is 1134 m²
What is the area of 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°
The area of the triangle = ( 1/2 ) x Length x Base
Given data ,
The value of t = 9 m
Let the base of the triangle be b = 4t
= 4 x 9
= 36 m
Let the height of the triangle be h = 7t
= 7 x 9
= 63 m
Now , the area of the triangle = ( 1/2 ) x Length x Base
So , substituting the values , we get
Area of the Triangle = ( 1/2 ) x 36 x 63
= 18 x 63 m²
= 1134 m²
Therefore , the area is 1134 m²
Hence , the area of the triangle is 1134 m²

Step-by-step explanation:
Hey! Pretty stranger :D
AsnwEr:
Number of girls in class = 15GivEn:
The ratio of no. of boys to no. of girls in a class is 4:5.Number of boys in class = 12To find:
Number of girls in class?Solution:
☯ Let number of girls be x.
Given that,
The ratio of no. of boys to no. of girls in a class is 4:5.Therefore,
→ 12/x = 4/5
→ x = 12 × 5/4
→ x = 60/4
→ x = 15
∴ Hence, number of girls in a class is 15.

Solve for m: -8 = m/-10 - 16
Answer:
m = -80
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightEquality Properties
Step-by-step explanation:
Step 1: Define
-8 = m/-10 - 16
Step 2: Solve for m
Add 16 to both sides: 8 = m/-10Multiply -10 on both sides: -80 = mRewrite: m = -80Answer:
We have this equation:
-8 = m/-10 -1
We can add 8 at both sides:
-8 + 8 = m/-10 -16 + 8
0 = m/-10 -8
Now, we can multiply -8 by -10 with the objective of having the same denominator (-10) in all numbers:
0 = m/-10 - 8*(-10)/-10
0 = m/-10 +80/-10
Now, we can delete all denominators
0 = m + 80
And we can say m = -80
Now, we can replace it to see if it's true:
-80/-10 - 16 = -8, so we know that's true
-80/-10 -16 = 8 - 16 = -8 ..

180-102=78
Answer:
Step-by-step explanation:
first find the final interior angle since we need it to find the exterior
60 + 42 = 102
180 - 102 = 78 degrees
then we just have to do 180 - 78 bc we have a straight line and straight lines are always 180 degrees
180 - 78 = 102 degrees
x = 102
you honestly could just take the 2 values you already know and add them and use that lol
