Write an
algebraic expression to represent the area of the shaded region:
2y
4y + 3
Answer:
4y^{2}+3y
Step-by-step explanation:
First you need to distribute the values.
(4y+3)(2y) Using the "Rainbow Method" to multiply the polynomials
You Should get
8y^{2}+6y
Since this is the area of the rectangle and we need to find the area of the shaded region you need to dived 8y^{2}+6y in half because the shaded region is half of the rectangle.
8y^{2}+6y/2
Doing this you will get
4y^{2}+3y

In an endurance race, Alyson rode her bicycle 7 miles less than Jeff. Together they rode 39 miles. How far did Alyson ride?
Answer:
Distance cover by Alyson = 16 miles
Step-by-step explanation:
Given:
Distance cover together = 39 miles
Assume;
Distance cover by Jeff = a
Distance cover by Alyson = a - 7
Find:
Distance cover by Alyson
Computation:
a + (a - 7) = 39
2a - 7 = 39
2a = 46
a = 23
Distance cover by Alyson = a - 7
Distance cover by Alyson = 23 - 7
Distance cover by Alyson = 16 miles

What is the solution for the following system of equations?
2x + y = 7
x - 2y = 6
I got you bro!
Answer:
{x,y} = {4-1}
You might be wondering how I got this, well here are the steps:
System of Linear Equations entered :
[1] 2x + y = 7
[2] x - 2y = 6
Graphic Representation of the Equations :
y + 2x = 7 -2y + x = 6
Solve by Substitution :
// Solve equation [2] for the variable x
[2] x = 2y + 6
// Plug this in for variable x in equation [1]
[1] 2•(2y+6) + y = 7
[1] 5y = -5
// Solve equation [1] for the variable y
[1] 5y = - 5
[1] y = - 1
// By now we know this much :
x = 2y+6
y = -1
// Use the y value to solve for x
x = 2(-1)+6 = 4
Solution :
{x,y} = {4,-1}
I hope this has helped you and have a wonderful day!
The dimensions of a rectangle are 5x + 2 and 3x – 4. What is the area of the rectangle in terms of x?

Preparation for the homecoming football game, members of the student body are painting the spirit rock in front of the school. If Angela works alone, it will take her five and a half hours. If Brandon works alone, it will take him 7 hours. If they work together, it will take them approximately hours ?
Answer:
3.08 hours
Step-by-step explanation:
Preparation for the homecoming football game, members of the student body are painting the spirit rock in front of the school.
If Angela works alone, it will take her five and a half hours.
If Brandon works alone, it will take him 7 hours. If they work together, it will take them approximately hours ?
This is calculated as:
The Number of hours they worked together = T
1/5.5 + 1/7 = 1/T
= 7 + 5.5/(5.5)(7)
= 12.5/38.5
1/T = 12.5/38.5
Cross Multiply
12.5T = 38.5
T = 38.5/12.5
T = 3.08 hours
The time required when Angela and Brandon work together, for the preparation for the homecoming football game, is 3.08 hours.
What is the relation between work and time?The total time taken is inversely proportional to the rate of work. If a unit of work is done in total n number of days, then the total work done in a day can is,
[tex]W_1=\dfrac{1}{n}[/tex]
In preparation for the homecoming football game, members of the student body are painting the spirit rock in front of the school.
If Angela works alone, it will take her five and a half hours. The work done by Angela in one hour is,
[tex]A=\dfrac{1}{5.5}\\A=\dfrac{2}{11}[/tex]
If Brandon works alone, it will take him 7 hours. The work done by Brandon in one hour is,
[tex]B=\dfrac{1}{7}[/tex]
The work done in one hour, when the work together,
[tex]A+B=\dfrac{2}{11}+\dfrac{1}{7}\\A+B=\dfrac{14+11}{77}\\A+B=\dfrac{25}{77}\\A+B=\dfrac{1}{3.08}[/tex]
Thus, the time required when Angela and Brandon work together, for the preparation for the homecoming football game, is 3.08 hours.

A grocery store receives a shipment of 700 oranges. The manager randomly selects 25 oranges to weigh. In that sample, 2 oranges weigh 5 ounces. How many oranges in the shipment can the manager predict weigh 5 ounces?
14
56
644
698
The number of oranges in the shipment can the manager predict weighing 5 ounces will be 56. Then the correct option is B.
What is the expected value?In parameter estimation, the expected value is an application of the weighted sum. Informally, the expected value is the simple average of a considerable number of individually determined outcomes of a randomly picked variable.
The expected value is given below.
E(x) = np
Where n is the number of samples and p is the probability.
A grocery store receives a shipment of 700 oranges. The manager randomly selects 25 oranges to weigh. In that sample, 2 oranges weigh 5 ounces.
Then the probability of the oranges that weigh 5 ounces is given as,
p = 2/25
Then the number of oranges in the shipment can the manager predicts weigh 5 ounces will be given as,
E(x) = 700 x 2 / 25
E(x) = 28 x 2
E(x) = 56
The number of oranges in the shipment can the manager predict weighing 5 ounces will be 56. Then the correct option is B.

A submarine submerges at the rate of 5min. if it descends from 20 m above the sea level :What will be the total depth it submerged if it is to reach 250m below sea?
Answer:
Submarine submerges at the rate of =5m/min
descend starts from = 20m
submarine have to reach = -250m
Distance between above sea level to below sea level = 250 + 20 = 270m
time taken to reach 270 m = 270/5= 54 minutes

Leon has $50 in a savings account that earns 10% interest, compounded annually. To the nearest cent, how much interest will he earn in 2 years?
Answer:
$10.50
Step-by-step explanation:
Interest = future value - amount saved
The formula for calculating future value:
FV = P (1 + r)^n
FV = Future value
P = Present value
R = interest rate
N = number of years
$50 x (1.1)^2 = $60.50
Interest = $60.50 - $50 = $10.50
