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

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.

Answer:
20 in²
Step-by-step explanation:
Divide the shape into two rectangles (see attached image)
Area of a rectangle = width × length
Area of rectangle 1
⇒ area = 2 × 3
= 6 in²
Area of rectangle 2
⇒ area = (5 - 3) × 7
= 2 × 7
= 14 in²
Total area
Total area = area of rectangle 1 + area of rectangle 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!
Which equation is true? 9x2 – 25 = (3x – 5)(3x – 5) 9x2 – 25 = (3x – 5)(3x 5) 9x2 – 25 = –(3x 5)(3x 5) 9x2 – 25 = –(3x 5)(3x – 5).
Answer:
9x² - 25 = (3x - 5)(3x + 5)
Step-by-step explanation:
(a + b)(a - b) = a² - ab + ab - b² = a² - b²
a² - b² = (a + b)(a - b)

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
