The graph shows a system of equations:
Y= -x - 2 y = 2x - 5 what is the solution (-1 , 3) (1 , -3) (1 , 3 ) ( -1, -3)

Answer:81

Step-by-step explanation:

Area = length x width

You have the area and the length so plug those numbers in.

364.5=27w

Divide both sides by 27 to isolate the width.

13.5=width

To find the perimeter you multiply the length by two and the width by two then add them together.

Perimeter=2L+2W

2x27=54

2x13.5=27

54+27=81

Answer:

There are multiple possible sets of dimensions for a rectangular prism with a volume of 10 cubic feet. Here are some possible solutions:

A rectangular prism with dimensions of 1 ft x 2 ft x 5 ft (length x width x height) would have a volume of 10 cubic feet, since 1 x 2 x 5 = 10.

A rectangular prism with dimensions of 2 ft x 1 ft x 5 ft (length x width x height) would also have a volume of 10 cubic feet, since 2 x 1 x 5 = 10.

A rectangular prism with dimensions of 0.5 ft x 1 ft x 20 ft (length x width x height) would also have a volume of 10 cubic feet, since 0.5 x 1 x 20 = 10.

A rectangular prism with dimensions of 5 ft x 1 ft x 2 ft (length x width x height) would have a volume of 10 cubic feet, since 5 x 1 x 2 = 10.

There are infinitely many other possible sets of dimensions for a rectangular prism with a volume of 10 cubic feet.

Answer:

60

Step-by-step explanation:

To find the appropriate average with weights assigned, we need to use the weighted average formula:

Weighted average = (w1 * x1 + w2 * x2 + w3 * x3) / (w1 + w2 + w3)

where

x1, x2, x3 are the marks obtained in Business, Science, and History respectively

w1, w2, w3 are the weights assigned to each subject

Substituting the given values, we get:

Weighted average = (660 + 568 + 4*50) / (6 + 5 + 4)

= (360 + 340 + 200) / 15

= 900 / 15

= 60

Therefore, the appropriate weighted average is 60.

Answer:To find the appropriate average, we need to calculate the weighted mean, which takes into account the different weights assigned to each mark.

The formula for the weighted mean is:

weighted mean = (w1x1 + w2x2 + w3x3) / (w1 + w2 + w3)

where w1, w2, w3 are the weights assigned to each mark, and x1, x2, x3 are the corresponding marks obtained by the student.

Plugging in the values given in the problem, we get:

weighted mean = (6 x 60 + 5 x 68 + 4 x 50) / (6 + 5 + 4)

weighted mean = (360 + 340 + 200) / 15

weighted mean = 900 / 15

weighted mean = 60

Therefore, the appropriate average of the marks obtained by the student is 60.

6/8 the product of 2/4and6/8

Step-by-step explanation:

2/4and6/8=4/8,12/16

For the distance and time data , the true statement to represent the speed is given by :

a. A graph formed by given distance and time represents Kassie’s speed would have a slope of 1.22.

Let the time on the graph of distance and time graph is 't'

Distance of the graph is 'd'

Speed = Distance / time

Let us consider two coordinates of distance and time on graph be :

( t₁ , d₁ ) = ( 3, 3.72 )

( t₂ , d₂) = ( 12, 14.88)

Speed is represented by the slope of distance and time

Speed = ( d₂ - d₁ ) / ( t₂ - t₁ )

           = ( 14.88 - 3.72 )/ ( 12 - 3 )

           = 11.16 / 9

           = 1.24 m/s  ___(1)

Equation of Kassie swims is d = 1.22t

It implies d/t = 1.22 ___(2)

From (1) and (2) we have :

Kassie speed represents the slope 1.22m/s.

Therefore, the true statement is option a. Kassie speed representing the slope equals to 1.22m/s.

The above question is incomplete , the complete question is:

Kassie and Luke timed each other during swim practice. The speed

at which Kassie swims is represented by the equation = 1.22,

where d is the number of meters she swims in t seconds. The speed

at which Luke swims is represented in the table.

                    Luke's speed

Time in seconds (t)    :   3                       6                     9                   12

Distance in meter (d) :   3.72                 7.44                11.66              14.88

Which of the following statements are true?

a. A graph of Kassie’s speed would have a slope of 1.22.

b. Luke’s rate of speed is 1.86 meters per second.

c. A graph of Luke’s speed would go through (0,0) and (1,24).

d. Kassie’s rate of speed is 0.02 meters per second slower than Luke’s rate of speed.

(1) Suppose x = 32.12353535... . Then 100x = 3212.353535... and 10000x = 321235.353535... .

Subtracting these gives

10000x - 100x = 321235.353535... - 3212.353535...

9900x = 321235 - 3212

9900x = 318023

x = 318023/9900

(2) By the same process as above, we start with

x = 2.333...

y = 4.151515...

Then

10x = 23.333...

==>  10x - x = 23.333... - 2.333...

==>  9x = 23 - 2

==>  x = 21/9

and

100y = 415.151515...

==>  100y - y = 415.151515... - 4.151515

==>  99y = 415 - 4

==>  y = 411/99

After this, we get

x + y = 2.333... + 4.151515...

==>  x + y = 21/9 + 411/99

==>  x + y = 231/99 + 411/99

==>  x + y = 642/99 = 214/33
