Answer:
$87.63
Step-by-step explanation:
Given data
Your bill= $76.20
Tip= 15%
Let us find the amount of 15% tip
=15/100*76.20
=0.15*76.20
=$11.43
Hence, the total bill is
=11.43+76.20
=$87.63

Answer:
Side of the rhombus is 12 cm. Let d1 = 2x cm , so d2 = 2x+6 cm
Now, 12^2 = x^2 + (x+3)^2 = 2x^2 + 6x+9 = 144, or
2x^2 + 6x-135=0, or
x^2+3x-67.5 = 0
x1 = [-3 +(9+270)^0.5]/2
= [-3+279^0.5]/2
= [-3+16.70329309]/2 = 6.851646544 cm [x2 will be negative and so inadmissible]
So d1 = 2x6.851646544 = 13.70329309 cm and d2 = 19.70329309 cm.
So the area of the rhombus is 13.70329309x19.70329309/2 = 135 sq cm.

] Consider a randomly shuffled deck of ten cards labeled {1, 1, 2, 2, 3, 3, 4, 4, 5, 5}, of which game play requires three to be drawn. Which one should be worth more points: A getting a pair of matching cards within the three, or B getting a set of three cards that can be arranged such that the sum of two of them is the value of the third (e.g. 1 2
Answer:
B should be worth more points.
Step-by-step explanation:
Given - Consider a randomly shuffled deck of ten cards labeled
{1, 1, 2, 2, 3, 3, 4, 4, 5, 5}, of which game play requires three
to be drawn.
To find - Which one should be worth more points:
A getting a pair of matching cards within the three,
or B getting a set of three cards that can be arranged such
that the sum of two of them is the value of the third.
Proof -
Given that, three cards has to be drawn.
So, total number of ways the card be drawn = ¹⁰C₃
= [tex]\frac{10!}{3! (10-3)!}[/tex]
= [tex]\frac{10!}{3! 7!}[/tex]
= [tex]\frac{10.9.8.7!}{3! 7!}[/tex]
= [tex]\frac{10.9.8}{3.2.1}[/tex]
= 120
⇒¹⁰C₃ = 120
Now,
Given that, A getting a pair of matching cards within the three
Sample space = { (1,1,2), (1,1,3).(1,1,4),(1,1,5);
(2,2,1),(2,2,3),(2,2,4),(2,2,5);
(3,3,1),(3,3,2),(3,3,4),(3,3,5);
(4,4,1),(4,4,2),(4,4,3),(4,4,5);
(5,5,1),(5,5,2),(5,5,3),(5,5,4) }
⇒n(A) = 20
Also,
B getting a set of three cards that can be arranged such that the sum of two of them is the value of the third
Sample space = { (1,1,2),(1,2,3),(1,3,4),(1,4,5),(2,2,4),(2,3,5) }
⇒n(B) = 6
Now,
P(A) = [tex]\frac{20}{120} = \frac{1}{6}[/tex] = 0.167
P(B) = [tex]\frac{6}{120} = \frac{1}{20}[/tex] = 0.05
We can see that, P(B) < P(A)
⇒B should be worth more points.
This is kinda easy ig helpppp tho

X
Answer:
5
Step-by-step explanation:
It’s a radius, so it’s 5.
The length of x in the circle shown will be 5 units.
What is a circle?A circle is a geometric shape that is created by drawing a point in an orbit around a fixed point while maintaining a fixed distance.
The longest line which can be drawn inside the circle will be the diameter.
Area of circle = πr² and the perimeter of circle = 2πr where r is the radius of the circle.
Given the circle with a radius of 5 units.
A radius is a line that goes from the center and touches the periphery of the circle.
Since the x line also goes from the center and touches to the periphery hence, x should be a radius.
Since the radius of a circle is always the same so
x = radius = 5

Step-by-step explanation: 1) because we are multiplying fractions all we have to do is multiply the fractions numerator by numerator and denominator by denominator so 1x8=7 and 2x10=20 so 1/2x7/10=7/20
2) 2x2=4 4x3=12 so 2/4x2/3=4/12 now we can simplify so 4 divided by 4=1 and 12 divided by 4=3 so 1/3
3) 1x1=1 10x2=20 so 1/10x1/2=1/20
4) 1x1=1 10x2=20 so 1/10x1/2=1/20
5) 1x6=6 2x10=20 so 1/2x6/10=6/20 so now we have to simplify so 6 divided by 2=3 and 20 divided by 2=10 so 3/10

Solve for x (use steps i need to learn this pls)
Answer:
x = 14
Step-by-step explanation:
The figure shows two chords intersecting each other. Based on the Theorem of Intersecting chords, the product the segments of each chord is equal to the product of the other. This means:
24*x = 21*16
24x = 336
Divide both sides by 24
24x/24 = 336/24
x = 14
What is the center and radius of the circle with the given equation x^2 + y^2 + 14x - 12y +69 = 0
Answer:
Center is (7,-6)
Our radius is 4
Step-by-step explanation:
Subtract 69 to both sides
Complete the square of the x terms and y terms.
[tex] {x}^{2} + 14x[/tex]
[tex] {y}^{2} - 12y[/tex]
(To complete the square divide the coefficient by 2 and square it).
[tex] (\frac{14}{2} ) {}^{2} = 49[/tex]
[tex]( \frac{ - 12}{2} ) {}^{2} = 36[/tex]
Add those terms to the full equation. Add 36 and 49 to the right side as well
[tex] {x}^{2} + 14x + 49 + {y}^{2} - 12y + 36 = 16[/tex]
Simplify the x and y terms into a binomial.
[tex](x + 7) {}^{2} + (y - 6) {}^{2} = 16[/tex]
Set the left side equal to zero separately to find the center and take the square root of the right side to find the radius.
[tex]x + 7 = 0[/tex]
[tex]x = - 7[/tex]
[tex]y - 6 = 0[/tex]
[tex]y = 6[/tex]
[tex]16 = {x}^{2} [/tex]
[tex]4 = x[/tex]
So our center is (-7,6)
Our radius is 4.
