Bobby has a party while his parents are away for the weekend. Bobby estimated that if his 9 friends hep him to clean the house, they will finish in time if they start 8 hours before his parents return. But after only two hours of cleaning, Bobby's parents call and say they are just two hours from home. How many more friends does Bobby need to call to help finish cleaning in time.
Bobby will need additional 20 friends to help finish cleaning in time.
Rate at which Bobby and his 9 friends are workingThe rate at which Bobby and his 9 friends are cleaning the house is determined as follows;
10 person ------> 8 hours
1 person -------->?
= 10 x 8 = 80 hours/person
When the parents are 2 hours from the house, Bobby will more friends working at the same rate to complete it in 2 hours time.
During this period Bobby and his friends have worked for 2 hours remaining 6 hours.
New rate;
10 person ------> 6 hours
1 person -------->?
1 person = 10 x 6 hrs = 60 hours per person
Total persons that will do the same work in 2 hours2 = 60/x
x = 60/2
x = 30 persons
Thus, Bobby will need additional 20 friends to help finish cleaning in time.

You roll two fair number cubes what is the probability that the sim of your rolls is 5 or higher
The probability that the sum of your rolls is 5 or higher is 13/18
How to determine the probability?In a roll of two fair die, we have the following parameters:
Sample size, n = 36Sum of 5 or higher = 26So, the probability is:
P = 26/36
Simplify
P = 13/18
Hence, the probability that the sum of your rolls is 5 or higher is 13/18

Find the measure of each angle in the problem. MG contains point T.
A. 100 and 80
B. 95 and 85
C. 50 and 40
D. 60 and 120
Answer:
A
Step-by-step explanation:
the angles are adjacent angles on a straight line and sum to 180°, so
5x + 4x = 180
9x = 180 ( divide both sides by 9 )
x = 20
then
∠ MTQ = 5x = 5 × 20 = 100°
∠ GTQ = 4x = 4 × 20 = 80°

Consider the division of 8y2 – 12y + 4 by 4y.
What are the values of a and b?
a = 2y and b = 3
a = and b = –3y
a = 2y and b = –3
a = and b = 3y
Notice that the dividend [tex]8y^2-12y+4[/tex] has tree terms with [tex]a=8y^2[/tex], [tex]b=-12y[/tex], c [tex]c=4[/tex]
Now, to divided our dividend [tex]8y^2-12y+4[/tex] by the monomial (single term) [tex]4y[/tex], the easiest thing to do is divide each term of the dividend by the monomial:
[tex]8y^2-12y+4[/tex] ÷ [tex]4y[/tex] = [tex]\frac{8y^2-12y+4}{4y}=\frac{8y^2}{4y}-\frac{12y}{4y}+\frac{4}{4y}=2y-3+\frac{1}{y}[/tex]
After performing the division we get that now [tex]a=2y[/tex] and [tex]b=-3[/tex]
We can conclude that the correct answer is a = 2y and b = –3

Four circles, each with a radius of 2 inches, are removed from a square.
Four circles, each with a radius of 2 inches, are removed from a square. What is the remaining area of the square?
(16 – 4π) in.2
(16 – π) in.2
(64 – 16π) in.2
(64 – 4π) in.2
Given:
Given that the radius of the circle is 2 inches.
We need to determine the area of the remaining square.
Area of a square:
Given that each circle has a radius of 2 inches.
Then, the diameter of each circle is 4 inches.
Hence, the side length of the square is 2 × 4 = 8 inches.
The area of the square is given by
[tex]A=s^2[/tex]
[tex]A=8^2[/tex]
[tex]A=64[/tex] [tex]in^2[/tex]
Thus, the area of the square is 64 square inches.
Area of the four circles:
The area of one circle is given by
[tex]A=\pi r^2[/tex]
Substituting r = 2, we have;
[tex]A=4\pi[/tex]
Thus, the area of one circle is 4π in²
The area of 4 circles is 4 × 4π =16π in²
Hence, the area of the 4 circles is 16π in²
Area of the remaining square:
The area of the remaining square is given by
Area = Area of the square - Area of four circles.
Substituting the values, we get;
[tex]Area=64-16\pi[/tex]
Thus, the area of the remaining square is (64 - 16π) in²
Hence, Option c is the correct answer.
Answer:
C. (64 – 16π) in.2

You invest $500 into an account that collects 1% interest each month. If you add an additional $50 each week, what will the balance of the account be after 5 months?
Answer:
$1555.91
Step-by-step explanation:
First Month:
You start out with $500.
You add $200 in the first month, and have 700.
Multiply 700 by 1.01, to add the interest and you get 707.
Second Month:
707 + 200 = 907
907 x 1.01 = 916.07
Third Month:
916.07 + 200 = 1116.07
1116.07 x 1.01 = 1127.2307
Fourth Month:
1127.2307 + 200 = 1327.2307
1327.2307 x 1.01 = 1340.503007 (round to .50)
Fifth Month:
1340.50 + 200 = 1540.50
1540.50 x 1.01 = 1555.905
Round to 1555.905 1555.91, and there's your answer. Hope this helps!

Solve the following system:
3x + 2y = 7
-4.5x - 3y = -10.5
Answer:
infinitely many solutions
Step-by-step explanation:
The system of equations :
3x + 2y = 7-4.5x - 3y = -10.5Multiplying Equation 1 times 3 and Equation 2 times 2 :
9x + 6y = 21-9x - 6y = -21Putting the equations in standard form after simplifying :
6y = -9x + 21 ⇒ y = -1.5x + 3.5-6y = 9x - 21 ⇒ y = -1.5x + 3.5As both equations are the same, the system will have infinitely many solutions.

A forest fire has been burning for several days. The burned area, in acres, is given
the equation y = (4, 800) • 2d, where d is the number of days since the area of the
fire was first measured.
Complete the following table:
Answer:
you gotta show a picture of the table in order for us to know what's missing from it
When d = -1, the value of y is 300 acres means that the area burned in the fire was 300 acres. When d = -3, the value of y is 1.17 acres means that the area burned in the fire was only 1.17 acres three days
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
we can use the given equation y = (4,800)2^d and substitute the values of d in the table to get the complete table.
Now the equation y = (4,800)2d for d when y = 4,800 and then subtract 7 from that value.
(4,800)2d = 4,800
2d = 1
d = 0.5
The fire had burned for 12 hours, before it measured 4,800 acres.
To determine the area the fire had burned a7 days before this measurement, we will then substitute d = -6.5 into the equation:
y = (4,800)2(-6.5) ≈ 0.00025 acres
