The probability of drawing 2 cards and they sum 21 is 4.83%, or 1 in 20.65. This is because there are 4 aces and 16 face cards in the deck, giving a total of 20 cards that can result in a sum of 21. With 52 cards in the deck, the probability is (20/52) x (19/51) x 100 = 4.83%.
The probability of drawing 2 cards and they sum 10 is 5.88%, or 1 in 17.01. This is because there are 16 cards (10s and face cards) that can result in a sum of 10. With 52 cards in the deck, the probability is (16/52) x (15/51) x 100 = 5.88%.
Given that you have drawn 10 of clubs and 4 of hearts, there are 49 cards remaining in the deck. To have a sum strictly larger than 21, the third card cannot be an ace, a face card, or a 10. There are 12 of these cards remaining in the deck. Therefore, the probability of drawing a third card that results in a sum strictly larger than 21 is (12/49) x 100 = 24.49%.

Around which line would the following cross-section need to be revolved to create a sphere?
circle on a coordinate plane with center at 1 on the x-axis and a radius of 1
y = x
y-axis
x = 1
y = 1
Answer:
I believe your answer would be y=1.
Step-by-step explanation:
The circle is located with its point on 1 of the x axis, and the cross section would be pulled straight from that term. So the cross section would need to be revolved around y = 1, instead.
This is just my best guess, so I hope it helps!
To get a sphere, we need to do a revolution around the line x = 1.
Which line should we use?
The line that we must use must be a line that divides the circle in two equal parts, so it must pass through its center.
We know that the center of our circle is the point (1, 0).
With that in mind, the two lines that we know that will divide the circle in two equal parts are:
y = 0x = 1(There are more lines, the above two are the simplest ones).
The only one that appears on the options is x = 1, so that is the correct option.

Can any one help me on this question ?
Answer:
70°
Step-by-step explanation:
2x +x + 80° + 70° = 360° { being sum of angles of quadrilateral }
3x + 150° = 360°
3x = 360° - 150°
3x = 210°
x = 70°
Hope it will help :)
Answer:
70
Step-by-step explanation:
Since sum of all angles in a quadrilateral is 360°
angle P+ angle Q + angle R + angle S= 360°
80+70+x+2x=360
3x= 360-150
3x = 210
x = 210/3
x= 70

__________________
2 1 14 -12 43 -31
so the answer is r=-31
Answer:
remainder = 60
Step-by-step explanation:
Given f(x) divided by (x - h) then the remainder is f(h)
f(x) = 2x³ + 15x² + 31x + 12 , then
f(1) = 2(1)³ + 15(1)² + 31(1) + 12

3. CONSTRUCTION A rectangular deck is built
around a square pool. The pool has side length s. The
length of the deck is 5 units longer than twice the side
length of the pool. The width of the deck is 3 units
longer than the side length of the pool. What is the
area of the deck in terms of s?
Did I do this right or was I supposed to leave it as a trinomial?
Answer:
[tex]s^2+11s+15[/tex]
Step-by-step explanation:
Let side length of pool=s
According to question
Length of rectangular deck , l=2s+5
Width of rectangular deck, b=3+s
We have to find the area of deck in terms of s.
We know that
Area of square=[tex](side)^2[/tex]
Area of rectangle=[tex]l\times b[/tex]
Using the formula
Area of pool=[tex]s^2[/tex]
Area of (rectangular deck+ pool)=[tex](2s+5)(3+s)[/tex]
Now,
Area of rectangular deck
=[tex](2s+5)(3+s)-s^2[/tex]
[tex]=6s+2s^2+15+5s-s^2[/tex]
=[tex]s^2+11s+15[/tex]
A collection of dimes and nickels is worth 3.30. if there are 42 coins in total how many of each kind of coin are there?
Answer:1 nickels =$0.05
1 dime= $0.1
Step-by-step explanation:
1 nickels =$0.05
1 dime= $0.1
let the number of nickels be x and that of dimes be y.
total number of coins is given by:
x+y=42
hence:
y=42-x.......i
total amount of cash will be:
0.05x+0.1y=3.30.........ii
substituting i in ii we get:
0.05x+0.1(42-x)=3.30
0.05x+4.2-0.1x=3.3
-0.05x=-0.9
x=-0.9/(-0.05)
x=18
hence the the number nickels is x=18, the number of dimes will be y=42-x=42-18=24
Darius is putting tiles on the roof of his house. After working for 3 1/3 hours, he has completed 4/5 of the roof. Can Darius put the titles on the enitre roof in 4 hours if he continues to work at the same rate?
Answer:
No.
Step-by-step explanation:
It is given that Darius is putting tiles on the roof of his house.
Darius had completed = [tex]$\frac{4}{5}$[/tex] th of the work
He takes time = [tex]$3 \frac{1}{3}$[/tex] hours to complete [tex]$\frac{4}{5}$[/tex] th of the work
The remaining work = [tex]$1 -\frac{4}{5}$[/tex]
[tex]$=\frac{5-4}{5}$[/tex]
[tex]$=\frac{1}{5}$[/tex]
∴ Darius completes [tex]$\frac{4}{5}$[/tex] th of the work in = [tex]$\frac{10}{3}$[/tex] hours
So, [tex]$\frac{1}{5}$[/tex] th of the work in = [tex]$\frac{10}{3} \times \frac{5}{4} \times \frac{1}{5}$[/tex] hours
[tex]$=\frac{10}{12}$[/tex] hours
Therefore total time taken to complete the work [tex]$=\frac{10}{3}+\frac{10}{12}$[/tex] hours
[tex]$=\frac{40+10}{12}$[/tex] hours
[tex]$=\frac{50}{12}$[/tex] hours
[tex]$=4\frac{2}{12}$[/tex] hours
[tex]$=4\frac{1}{6}$[/tex] hours
Thus, Darius continues to work at the same rate will not be able to complete the work in 4 hours.
The angles of quadrilateral are in the ratio 3 : 5 : 9 : 13. Find all the angles of the quadrilateral.
Step-by-step explanation:
let the ratio be x
now,
3x+5x+9x+13x=360°(sum of angle of quadrilateral is 360°)
30x=360°
x=360/30
x=12°
then,
3x=3×12=36°
5x=5×12=60°
9x=9×12=108°
13x=13×12=156°
so,the angles of quadrilateral are 36°,60°,108°& 156°
hope it helps.
Which number line represents the solution to the inequality x - 3 > 2
Answer: x > 5
Step-by-step explanation: To solve for x in this inequality, our goal is the same as it would be if this were an equation, to get x by itself on one side.
Since 3 is being subtracted from x, we add 3 to
both sides of the inequality to get x > 5.
When graphing x > 5, we have an open circle on 5 and the
open circle tells us that 5 is not part of our answer.
Then we draw an arrow going to the right to represent
all possible solutions to this inequality, any number greater than 5.

triangle ABD~ triangle DBC the perimeter of triangle ABD=36, fond the perimeter of triangle DBC.
Answer:
Perimeter of ΔDBC = 48 units
Step-by-step explanation:
It's given in he question,
ΔABD ~ ΔDBC
Therefore, by the definition of similar triangles,
Corresponding sides of both the triangle will be proportional.
[tex]\frac{AB}{DB}= \frac{BD}{BC}= \frac{AD}{DC}[/tex]
[tex]\frac{9}{12}= \frac{12}{16}= \frac{AD}{DC}[/tex]
[tex]\frac{3}{4}=\frac{AD}{DC}[/tex]
AD = [tex]\frac{3}{4}DC[/tex] ----------(1)
Since, perimeter of ΔABD = 36,
AB + BD + AD = 36
9 + 12 + AD = 36
AD = 36 - 21
AD = 15
From equation (1),
15 = [tex]\frac{3}{4}(DC)[/tex]
DC = 20
Perimeter of ΔDBC = DB + BC + DC
= 12 + 16 + 20
= 48
Therefore, perimeter of ΔDBC = 48 units is the answer.
