Lets Find the area of the trapezoidal face

Base 1 = 15

Base 2 = 37

Height = 25.7

Formula for area of trapezoid

(b1+b2)h/2

Lets Input

(15+37)25.7/2

1336.4/2 = 668.2

Now lets multiply by 20, or the length

668.2 x 20 = 13364

Note we could have saved time by multiplying 1336.4 x 10 because 20/2 = 10

Joshua invested $750 in an account paying an interest rate of 3\tfrac{1}{4}3 4 1 % compounded quarterly. Josiah invested $750 in an account paying an interest rate of 2\tfrac{5}{8}2 8 5 % compounded annually. After 18 years, how much more money would Joshua have in his account than Josiah, to the nearest dollar?

Answers

Answer:

Due to the difference in the interest rate and the quarterly compounding, Joshua will have $212.24 more than Josiah.

Step-by-step explanation:

Giving the following information:

Joshua:

Initial investment (PV)= $750

Interest rate (i)= 0.0341/4= 0.008525

Number of periods (n)= 18*4= 72 quarters

Josiah:

Initial investment (PV)= $750

Interest rate (i)= 0.0285

Number of periods (n)= 18 years

To calculate the future value of each one, we need to use the following formula:

FV= PV*(1 + i)^n

Joshua:

FV= 750*(1.008525^72)

FV= $1,381.98

Josiah:

FV= 750*(1.0285^18)

FV= $1,169.74

Due to the difference in the interest rate and the quarterly compounding, Joshua will have $212.24 more than Josiah.

Ethan spent 12.5% of the money in his pocket on dinner. His dinner cost $15.25. How much did he have in his pocket? Group of answer choices $102.00 $172.36 $190.63 $122.00

Answers

Answer:

$122

Step-by-step explanation:

Let total money in his pocket = $ x

12.5% of x = $ 15.25

[tex]\frac{12.5}{100}*x= 15.25[/tex]

Multiply both sides by 100

12.5 *x = 15.25*100

125.5 *x = 1525

Divide both sides by 125.5

[tex]x = \frac{1525}{12.5}\\\\[/tex]

x = $ 122

he baseball team pitcher was asked to participate in a demonstration for his math class. He took a baseball to the edge of the roof of the school building and threw it up into the air at a slight angle so that the ball eventually fell all the way to the ground.

Solve the system of equations graphically 3x-y=4, 2y+x=6

Answers

Answer:

y=2 x=2

Step-by-step explanation:

x = -2y + 6

3•(-2y+6) - y = 4

- 7y = -14

7y = 14

y = 2

x = -2y+6

y = 2

x = -2(2)+6 = 2

x=2

Step-by-step explanation:

solve for y in both equations

3x-y=4

subtract 3x from both sides

-y=4-3x

multiply the equation by -1

y=-1(4-3x)

2y+x=6

subtract both sides by x

2y=6-x

divide both sides by 2

y=(6-x)/2

Now set the y values equal to each other

-1(3x-4)=(6-x)/2

-3x+4=(6-x)/2

multiply both sides by 2

-6x+8=6-x

add 6x to both sides and subtract 6 to both sides

2=x

put 2 back into x for y=(6-x)/2

y=2

Hope that helps :)

An aquarium holds 11.35 cubic feet of water, and is 2.8 feet long and 1.5 feet wide. What is its depth? Round your answer to the nearest whole number.

Answers

Answer:

3 feet

Step-by-step explanation:

the volume of the aquarium is V= Lx wx H

it is as of now given that V=11.25 cubic feet, so 11.25=LxWxH

H tallness and it is the aquarium's profundity

H=11.25/L xW= 11.25/2.5x1.5= 3 feet

Answer:

The depth is 3 ft

Step-by-step explanation:

The equation for volume is V = length * height * depth

change the equation for depth

depth = volume / (length * height)

fill the equation and solve

depth = 11.35 / (2.8 * 1.5)

depth = 11.35 / 4.2

depth = 2.70238095 rounded to 3

Castel and Chelsea are selling pies for a school fundraiser. Customers can buy cherry pies and lemon meringue pies. Castel sold 1 cherry pie and 5 lemon meringue pies for a total of $69. Chelsea sold 5 cherry pies and 7 lemon meringue pies for a total of $129. Find the cost each of one cherry pie and one lemon meringue pie.

Answers

Answer:

the cost each of one cherry pie and one lemon meringue pie is 9 and $12 respectively

Step-by-step explanation:

The computation of the cost of one cherry pie and the lemon meringue pie is shown below:

Let us assume the cherry pie be x

And, the lemon meringue pie be y

So according to the question

x + 5y = $69

5x + 7y = $129

Now multiply by 5 in the equation 1

5x + 25y = $345

5x + 7y = $129

18y = $216

y = $12

And, x would be

x + 5($12) = $69

x = $9

Hence, the cost each of one cherry pie and one lemon meringue pie is 9 and $12 respectively
