Step-by-step explanation:
each game of cribbage "binds" 4 people, each hand of chess 2 people.
15 games of cribbage means 15×4 = 60 people are playing. that leaves 0 people and therefore 0 games for chess.
2 games of chess means 2×2 = 4 people are playing.
that leaves 60-4 = 56 people for cribbage making 56/4 = 14 games of cribbage.
13 games of cribbage means 13×4 = 52 people are playing. that leaves 60-52 = 8 people for chess making 8/2 = 4 games of chess.
14 games of chess means 14×2 = 28 people are playing, that leaves 60-28 = 32 purple for cribbage making 32/4 = 8 games of cribbage.
0 people of cribbage means nobody is playing this game, that leaves all 60 people to play chess making 60/2 = 30 games of chess.

What is the measure of XYZ?
x
A. 136
B. 34°
C. 68°
D. 22°
Angles can be measured in degrees and radians
The measure of angle XYZ is 34 degrees
How to determine the measure of XYZFrom the question, the measure of arc XY is 68 degrees
The measure of angle XYZ is then calculated as:
Angle XYZ = 0.5 * Arc XY
This gives
Angle XYZ = 0.5 * 68
Evaluate the product
Angle XYZ = 34
Hence, the measure of angle XYZ is 34 degrees

Jamie has a rectangular pool that has a length of 12 feet and a
perimeter of 40 feet. What is the width of the pool?
Answer:
8 feetStep-by-step explanation:
Given,
Perimeter of a rectangular pool (P) = 40 feet
Length of the pool (l) = 12 feet
Let,
Width of the pool be = w
As we know,
Perimeter of a rectangle = 2(length + width)Therefore,
By the problem,
=> 2(l + w) = P
[On substituting the values of l = 12 and P = 40]=> 2(12 + w) = 40
[On multiplying 2 with 12 and w]=> 24 + 2w = 40
[On subtracting both sides with 24]=> 24 - 24 + 2w = 40 - 24
[On Simplifying]=> 2w = 16
[On Dividing both sides with 2]=> [tex]\frac{2w}{2}[/tex] = [tex]\frac{16}{2}[/tex]
[On Simplifying]=> w = 8
Hence,
The required width of the pool is 8 feet. (Ans)
Answer:
The Width of the pool would be 8 feet/ft. .
Step-by-step explanation:
According to the Question Given:
Perimeter = 40 ft/feet
Length of the pool = 12 ft/feet
To Find:
The width/breadth of the pool
Solution:
We know that,
[tex] \boxed{\tt \: Perimeter \: of \: Rectangle = 2(l + b)}[/tex]
So Put their values accordingly:
Perimeter of The Rectangle = 40Length[L] = 12[tex]\longrightarrow \tt \: 40 = 2(12 + b)[/tex]
We got an equation.By this method we can easily find the breadth/width of the pool.
Solve this equation:
[tex]\longrightarrow \tt40 = 2b + 24[/tex]
Flip the equation:
[tex]\longrightarrow \tt2b + 24 = 40[/tex]
Transpose 24 to the RHS[remember to change its sign]:[tex]\longrightarrow \tt2b = 40 - 24[/tex]
Simplify:[tex]\longrightarrow \tt2b = 16[/tex]
Divide both sides by 2:
[tex] \tt\longrightarrow \cfrac{2b}{2} = \cfrac{16}{2} [/tex]
Use Cancellation method and cancel LHS and RHS:[tex]\tt\longrightarrow \cfrac{ \cancel2 {}^{1} b}{ \cancel2} = \cfrac{ \cancel{16} {}^{8} }{ \cancel2} [/tex]
[tex]\longrightarrow \tt1b = 8[/tex]
[tex]\longrightarrow \tt{b} =\boxed{\tt 8 \: feet}[/tex]
Hence, the breadth/width of the pool would be 8 ft./feet .

Question 3 (Multiple Choice Worth 1 points)
(02.04 MC)
Choose the equation that represents a line that passes through points (-6, 4) and (2,0),
Previous Question
Answer:
y = 8
Step-by-step explanation:
The line that contains points (0, 8) and (8, 8) is a horizontal line in which every point has 8 as its y-coordinate.
Equation: y = 8
y=-1/2x+1 is the equation that represents a line that passes through points (-6, 4) and (2,0)
What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
the equation of a line that contains the points (0,8) and (8,8)
Slope=0
We need to find the y intercept
8=b
y=8 is the equation of a line that contains the points (0,8) and (8,8)
Now let us find the equation that represents a line that passes through points (-6, 4) and (2,0).
m=0-4/2+6
=-1/2
Now find the y intercept
0=2(-1/2)+b
b=1
y=-1/2x+1 is the equation that represents a line that passes through points (-6, 4) and (2,0),
Hence, y=-1/2x+1 is the equation that represents a line that passes through points (-6, 4) and (2,0)

c) The area of a rectangle is 70 cm and it is 7 m broad. (i) Find its length (ii) Find its perimeter
Answer:
34cm
Step-by-step explanation:
[tex]Solution,\\\\Area=70cm^{2} \\\\Breadth(b)=7cm\\\\Now,\\\\Length=\frac{Area}{Breadth}\\\\Length=\frac{70cm^{2} }{7cm} \\\\Length=10cm\\\\Again,\\\\Perimeter=2(l+b)\\\\Perimeter=2(10cm+7cm)\\\\Perimeter=34cm[/tex]
The required length and perimeter of the rectangle are 7 cm and 34 cm respectively.
The rectangle is 4 sided geometric shape whose opposites are equal in lengths and all angles are about 90°.
Here,
Let the length of the rectangle be l,
Now,
According to the question,
Area of the rectangle, = l × w
70 = l × 7
l = 70 / 7
l = 10 cm
Now,
Perimeter of the rectangle = 2[l + w]
= 2 [10 + 7]
= 34 cm
Thus, the required length and perimeter of the rectangle is 7 cm and 34 cm respectively.

An airplane is flying at an altitude of 33,000 feet. It needs to reduce its altitude by 6% to avoid some turbulence. After it passes the turbulence, it increases its altitude by 5000 feet.
What is the final altitude of the airplane?
Enter your answer in the box.
Step-by-step explanation:
100% = 33,000 ft
1% = 100%/100 = 33000/100 = 330 ft
6% = 1% × 6 = 330 × 6 = 1980 ft
that means the plane has to go down 1980 ft to
33,000 - 1980 = 31,020 ft
and then it goes up by 5000 ft :
31,020 + 5000 = 36,020 ft
that is the final altitude.
Answer:
The final altitude of the airplane is 36,020

Answer:

Step-by-step explanation:
The area of a triangle is given by the formula ...
A = 1/2bh
Here, it is convenient to choose the base as the vertical segment between y=-5 and y=3. Its length is 3 -(-5) = 8 units.
The height of the triangle is the difference in x-coordinates between that segment and the opposite vertex: 6 -2 = 4.
Then the area is ...
A = 1/2(8)(4) = 16 . . . square units

The quadrilaterals JKLM and PQRS are similar.
Find the length x of PQ.
PLS HELP ME and dont give me the answer 2.4 its wrong
Answer:
[tex]x[/tex] = 2.8
Step-by-step explanation:
If the quadrilaterals are similar, then the ratios of corresponding sides will be equal:
KL : QR = 4 : 5.6 = 4 / 5.6 = 5/7
JM : PS = 7 : 9.8 = 7 / 9.8 = 5/7
LM : RS = 3 : 4.2 = 3 / 4.2 = 5/7
This shows that the ratio of KJ : QP = 5/7
KJ : QP = 2 : [tex]x[/tex] = 2 / [tex]x[/tex]
Therefore, [tex]\frac{2}{x}=\frac{5}{7}[/tex]
cross multiply: 14 = 5[tex]x[/tex]
Divide both sides by 5: [tex]x[/tex] = 2.8
