A marble is picked at random. Without putting the first marble back, a second marble is picked at random. Find the probability that first marble picked is green and second marble picked is red. Write your result as a percentage.
Answer:
Probability = 1/5 = 20%
Step-by-step explanation:
Prob (1st marble green) = Green Marbles / Total Marbles = 3/6 = 1/2
Pr (2nd marble red), without replacement = Red Marbles / Left Total Marbles = 2/5
Prob (1st marble green, & 2nd marble red) = 1/2 x 2/5 = 1/5
Prob in percent = 1/5 x 100 = 20%

Step-by-step explanation:
the cost of fencing a circular field at the rate of Rs 12. per metre is Rs 2640 . find the radius of the field
Radius = 35 m
Step-by-step explanation:Given:Cost of fencing circular field is Rs 2640 at rate of Rs 12 per metre.
To Find:What is the radius of the circular field ?
Solution:Let the radius of circular field be r metre.
Here , if we'll divide the total cost by per metre cost of fencing then we'll get circumference of the circular field.
★ Circumference = Total cost/Cost per metre ★➯ Circumference = 2640/12
➯ 220 m
As we know that , formula of circumference is
★ Circumference = 2πr ★
⟹ 220 = 2 × 22/7 × r⟹ 220 = 44/7 × r⟹ 220 × 7/44 = r⟹ 20 × 7/4 = r⟹ 5 × 7 = r⟹ 35 = rHence, the radius of circular field is 35 metre.
Answer:
Solution given:
total cost =Rs 2640
rate=Rs 12/metre
We have
circumference of circle =[tex] \frac{total cost}{rate} = \frac{2640}{12} [/tex]
2πr=220m
r=[tex] \frac{220}{2π} [/tex]=35.01
r=35m(approximately)
the radius of the field is 35m.

Find the sum of the first 10 terms for the following sequence: a = {-1, 2, 5, ... }
Answer:
see, to find the next number, you need to add three to the last one
for example, the 3 was added to 2, so we have five here
5+3=8
8+3=11
and ....
so the next ten numbers are:
8, 11, 14, 17,20,23,26,29,32,35

Q19. Look at the image.
Answer:
It's C
Step-by-step explanation:
Because if you look at the other numbers they all add up to the next number by 4. 4+4=8 8+4=12 12+4=16 16+4=20 20+4=24
Therefore, x intercept is 24 and y intercept is 18. Hope this is correct if it's not correct then I'm very sorry. Have a nice day. ;)

What is the volume of the sphere with a diameter of 18 centimeters? Round to the nearest
hundredth.
Answer:
3054.024cm^3
Step-by-step explanation:
Given data
Diameter= 18cm
Radius= 9cm
The expression for the volume of a sphere is given as
Volume = 4/3πr^3
Volume= 4/3*3.142*9^3
Volume= 4/3*3.142*729
Volume= 9162.072/3
Volume= 3054.024 cm^3
Hence the volume is 3054.024cm^3

Kate has 3 quarts of a 5% sugar solution she wants to mix this with 2478% sugar solution and X quarts of a 12% sugar solution to make a 10% sugar solution how many quarts of a 12% sure solution to Katie‘s
Answer:
The volume of the 12% sugar solution required, 'X' for a given volume of the 8% sugar solution, 'Y' is;
X = (2·Y + 15)/2
When the volume of the 8% sugar solution, Y = 2 quartz, the volume of the 12% sugar solution required, X = 9.5 gallons
Step-by-step explanation:
The data of the sugar solutions are;
The volume of 5% sugar solution Kate has = 3 quarts
The volume of the 12% sugar solution = X
Let 'Y' represent the volume of the 8% sugar solution, we have;
The volume of the resultant solution, Z = X + Y + 3
The concentration of the resultant solution = 10%
0.05 × 3 + 0.08·Y + 0.12·X = 0.1·(X + Y + 3)
Solving gives the relationship between the volume of the 12% sugar solution, 'X', and the 8% sugar solution, 'Y' in quartz, as follows;
X = (2·Y + 15)/2
When the volume of the 8% sugar solution, Y = 2 quartz, we have;
X = (2 × 2 + 15)/2 = 9.5
Therefore, the volume of the 12% sugar solution Katie requires to make the 10% sugar solution is 9.5 quartz.

Math HW Mr Thompson May 24
Answers:
B) 0A) 27D) 50See the diagram below.C) 143================================================
Explanations:
Refer to the top left corner of the table. This is the intersection of the "less than 1 year" column and "antlers" row.Add up everything in the "1 year or older" column to get 12+15 = 27.There are 0+12 = 12 deer with antlers, and 23+15 = 38 deer with no antlers. I'm adding across the rows. This in turn means there are 12+38 = 50 deer total. You could also add across the columns, meaning we have 0+23 = 23 deer less than 1 years old, and 12+15 = 27 deer that are 1 year or older. So we have 23+27 = 50 deer total. The explanation is lengthy. There's not much room here so I'll explain in the section below. Refer to the table below as well.Dividing everything by 143 will help us get the values into percentages. For instance, 62/143 = 0.4336 = 43.36% approximately represents the number of people who wear a belt and also wear a watch (top left corner).-----------
Explanation for problem 4
We have 68 people who split the check out of 122 total. That leaves 122-68 = 54 people who don't split the check. These two values are the row totals for rows 1 and 2 in that order. So you'll have 68 at the end of row 1, and 54 at the end of row 2. Refer to the diagram below.
We have 56 people who prefer to skip dessert, meaning 122-56 = 66 people who order desert. We'll have 66 followed by 56 along the first two items in the bottom row. The grand total 122 is in the bottom right corner. The 122 is both in the total row and total column.
Then we're told that 50 people order desert and split the check. We had 68 people split the check, leaving 68-50 = 18 people who split the check, but didn't get dessert. For the first row, we have the values 50, 18, and 68. Note that 50+18 = 68.
In the second row, we must have the values 16, 38, and 54 in that order. The blank spaces are filled in using the same ideas as I've discussed in previous paragraphs.
The terms in gray boxes represent the totals, which would be left out when forming the table in your final answer. Meaning you'll have a 2x2 table instead of a 3x3 table.

64-50.27 = 13.73 (rounded)
Step-by-step explanation:
Square = side^2 - side =8 (4+4)
8*8 = 64
Circle area= pi r^2
16 pi = 50.27
Square-pi*r^2 = answer
64-16pi(not rounded)
