Step-by-step explanation:

3/5, 1/2, 2/3, and 3/4 must be 3 or lower if added together.

We need to find the LCM of the denominators. The LCM, or lowest common multiple, of the denominators is 60. So we have to multiply the fractions by the LCM and add them up.

36 + 30 + 40 + 45 = 151.

60 x 3 = 180.

151 isn't up to 180, so yes. And also, if you divide 151 by 60, you would get 2.52 approximately.

Use the formula to find the volume.

Finding the volume:

Volume of rectangular prism = L x H x B=> Volume of rectangular prism = 7 x 6 x 8=> Volume of rectangular prism = 336 m³

The volume of the rectangular prism is 336 m³.

Answer:

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 area of the triangle

Answers

Answer:

   16 square units

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

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.

Answers

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

How to determine the measure of XYZ

From 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

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?

Answers

Answer:

8 feet

Step-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 .

PLS HELP ME and dont give me the answer 2.4 its wrong

Answers

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

What is a rectangle?

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.

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)
