The probability of selecting a yellow marble is #of yellow marbles/total # of marbles= 6/30 or .2 or 20%
If there are 300 marbles in the bag, a good estimate for the total number of red marbles in the bag is 90.
9/30=.3 = the percentage of red marbles
.3(300) = 90
Step-by-step explanation:
Build a rectangle 12 cm high and 5 cm wide (Paint it). Then a) Find the perimeter of the rectangle. B) Find the area of the rectangle. Aiuda porfis.
Length of the rectangle is 12 cm
Breadth of the rectangle is 5 cm
Perimeter is the sum of all sides. For rectangle it is given by :
P = 2(l+b)
⇒ P=2(12+5)
P = 34 cm
Area of a rectangle is equal to the product of its length and breadth.
So,
A = lb
A = 12 cm × 5 cm
⇒A = 60 cm²
Hence, perimeter is 34 cm and area of rectangle is 60 cm².
Answer:
a. 
b. 
c. 
d. 
Step-by-step explanation:
Given
Solving (a): When g(x) = 0
Substitute 0 for g(x)
Solve for 8x
Solve for x
Solving (b): when x = 0
Substitute 0 for x
Solving (c): When g(x) = -5
Substitute -5 for g(x)
Solve for 8x
Solve for x
Solving (d): When x = 3
Substitute 3 for x
