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

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

Answer:

The y-intercept of this line is 2.

Step-by-step explanation:

To find where this line reaches the y axis, you simply need to assign the value 0 to x, and solve for y:

[tex]2x + 3y = 6\\2(0) + 3y = 6\\3y = 6\\y = 6/3\\y = 2[/tex]

So the y intercept of that line is 2

Answer:

Well the original price would be $44

Step-by-step explanation:

So make an equation

Lets make X stand for the price before the deduction

so x-x(0.3)=30.80

Subtracting the X by x(0.3) would tell us the price, the 0.3 stands for 30 percent and we know its 30 percent of X so we subtract that since 0.3x would give the change

Now just solve the equation

You’ll get 44.

Answer:

m = -80

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Equality Properties

Step-by-step explanation:

Step 1: Define

-8 = m/-10 - 16

Step 2: Solve for m

Answer:

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 ..

Answer:

2.3y+3.2-y=2.1+1.3y+1.1

Step-by-step explanation:

The first equation has one solution: z = 0.25.

The second equation has infinitely many solutions.

The third equation has one solution: x = -10/3.

The fourth equation has one solution: r = 2.

Two or more expressions with an Equal sign is called as Equation.

(a) 2.2z+3z=4.5-3.2

Simplifying the left-hand side, we get: 5.2z = 1.3

z = 1.3/5.2 = 0.25

Therefore, the equation has one solution: z = 0.25.

(b)2.3y+3.2-y=2.1+1.3y+1.1

1.3y + 3.2 = 2.2 + 1.3y

Therefore, the equation has infinitely many solutions.

(c) 2/3x+2/3+1/5x=2/3x

Simplifying the left-hand side, we get: 1/5x + 2/3 = 0

1/5x = -2/3

x = -10/3.

(d) 20+4r=32-2r

6r = 12

r = 2

Therefore, the equation has one solution: r = 2.

Hence, The first equation has one solution: z = 0.25.

The second equation has infinitely many solutions.

The third equation has one solution: x = -10/3.

The fourth equation has one solution: r = 2.

Step-by-step explanation:

If baseball team scored 5 more runs in its second game than its first. The team scored twice as many runs as the first game in the third game. The total number of runs in all three games was 29.Then 11 runs were scored in the second game

Two or more expressions with an Equal sign is called as Equation.

Let the runs scored by team in first game be x.

The team scored 5 more runs in its second game than its first.

x+5

The team scored twice as many runs as the first game in the third game.

2x

The total number of runs in all three games was 29

This we can write as x+x+5+2x=29

Add x variable terms

4x+5=29

Subtract 5 on both sides

4x=24

x=6

So the score in the second game will be x+5=6+5=11

Hence, 11 runs were scored in the second game
