-x-4y=-37 "-2x-5y=-53"

Answers

Answer:

  (x, y) = (9, 7)

Step-by-step explanation:

There are numerous ways to find the solution to a system of equations. A quick and easy one is to use a graphing calculator. The attachment shows the solution to be ...

  (x, y) = (9, 7)

__

You can also look for opportunities to do substitution or elimination. Here, the x-coefficients differ by a factor of 2, so it is convenient to subtract twice the first equation from the second. This eliminates the x-variable.

  (-2x -5y) -2(-x -4y) = (-53) -2(-37)

  3y = 21 . . . . . . simplify

  y = 7 . . . . . . . . divide by 3

  -x -4(7) = -37 . . . . . substitute into the first equation

  -x = -9 . . . . . . . . . . . add 28

  x = 9

The solution is (x, y) = (9, 7).

Step-by-step explanation:

Substitute the points for x and y, until you find the one that makes the equation true.

A. (-5, 3)

-3x + 4y < 20 <== substitute

-3(-5) + 4(3) < 20

15 + 12 < 20

27 < 20

This statement is false (27 is greater than 20, not less than)

B. (-3, 5)

-3x + 4y < 20

Answer:

[D] (-1,3)

Step-by-step explanation:

To know which ordered pair is in the solution set of -3x+4y < 20 we first need to identify the x-value in the ordered pair and plug it into the equation. When simplify, on the condition the y-value you get is identical as the y-value in the ordered pair, then that ordered pair is a solution to the equation.

Now let's solve:  

To find the solution of the equation is ordered pair substitute the value of x and y co-ordinate to check set of ordered pair is the solution of the given equation.

Given:

-3x + 4y < 20

[A] (-5,3)

-3(-5)+4(3)<20

The left side 27 is not less than the right side 20, which means the statement is false

-3x + 4y < 20

[B] (-3,5)

-3(-3)+4(5)<20

The left side 29 is not less than the right side 20, which means the statement is false

-3x + 4y < 20

[C] (1,7)

-3(1)+4(7)<20

The left side 25 is not less than the right side 20, which means that the given statement is false.

-3x + 4y < 20

[D] (-1,3)

-3(-1)+4(3)<20

The left side 15 is less than the right side 20, which means that the given statement is always true.

Hence, Answer is [D] (-1,3)

What is addition?

Addition is one of the four basic operations of arithmetic, The addition of two whole numbers results in the total amount or sum of those values combined.

Addition is the process of finding the total, or sum, by combining two or more numbers.

An example of addition is: 5 + 11 + 3 = 19.

Given that, Roy bought a 25 pound bag and a 10 pound bag of pet food we need to find that how many pounds of pet food did he buy

Since, we are required to find what amount of pet food did Roy bought from the market, here we will simply add both the amounts to get the total amount.

Total food =  25 pound bag + 10 pound bag

= 35 pound bag

Hence, Roy bought 35 pounds of pet food.

Through a regular hexagonal prism whose base edge is 8 cm

Whose height is 12 cm, a hole in the shape of a right prism

What is the formula for the total surface area?

Total surface area=2(area of the base)+parameter of base×Height

Height=8cm

Parameter of base=12(2)=24

area of the base=6×root3/4×4^2

We use the given value in the formula

Answer:

Let the woman's age be x

The mother's age is 2x.

The sum of the ages is 75.

Answer:

Area = 26 sq units

Step-by-step explanation:

If you put the points on a graph then you can see what you are working with. The parallelogram you can just count the squares to find the base and height. base = 6 and height = 1.

A = b • h = 6•1 = 6

To find the lengths of the sides for the rectangle you must use distance formula or pythagorean theorem. I have shown this using Pythagorean theorem. The short side of the rectangle is marked x and calculated to have length sqroot10. See image.

The graph shows the length is twice as long. But I showed a separate calculation also using pythag.thm. to find the length of y, the long side is sqroot40.

Area of rectangle is:

A = b•h OR L×W

A=sqrt10×sqrt40

A cylinder has a radius of 3 ft and a height of 5 ft. Find the volume

Answers

Question :-

A Cylinder has a Radius of 3 Ft and a Height of 5 Ft . Find the Volume .

Answer :-

Volume of Cylinder is 141.42 Ft³ .

Explanation :-

As per the provided information in the given question, we have been given that the Radius of the Cylinder is 3 Ft . The Height is given as 5 Ft . And, we have been asked to calculate the Volume of Cylinder .

For calculating the Volume , we will use the Formula :-

[tex] \bigstar \: \: \: \boxed{ \sf{ \: Volume \: _{Cylinder} \: = \: \pi {r}^{2}h \: }} [/tex]

Where ,

R denotes to RadiusH denotes to Height

Therefore , by Substituting the given values in the above Formula :-

[tex] \Longrightarrow \: \: \: \sf { Volume \: _{Cylinder} \: = \: \pi {r}^{2}h } [/tex]

[tex] \Longrightarrow \: \: \: \sf { Volume \: _{Cylinder} \: = \: \dfrac {22}{7} \: \times \: ({3})^{2} \: \times \: 5 } \\ [/tex]

[tex] \Longrightarrow \: \: \: \sf { Volume \: _{Cylinder} \: = \: \dfrac {22}{7} \: \times \: 9 \: \times \: 5 } \\ [/tex]

[tex] \Longrightarrow \: \: \: \sf { Volume \: _{Cylinder} \: = \: \dfrac {22\: \times \: 9 \: \times \: 5 }{7}} \\ [/tex]

[tex] \Longrightarrow \: \: \: \sf { Volume \: _{Cylinder} \: = \: \dfrac { \: 990 \: }{7}} \\ [/tex]

[tex] \Longrightarrow \: \: \: \bf { Volume \: _{Cylinder} \: = \: 141.42 } [/tex]

Hence :-

Volume of Cylinder = 141.42 Ft³ .

[tex] \underline {\rule {180pt}{4pt}} [/tex]

Answer:

Volume of cylinder is 141.3 ft³ ( Taking value of π as 3.14 )

Step-by-step explanation:

Question : -

A cylinder has a radius of 3 ft and a height of 5 ft. Find the volume .

Given : -

Radius of cylinder = 3 ft

Height of cylinder = 5 ft

To Find : -

We have to , volume of Cylinder .

Formula Used : -

[tex] \boxed{ \sf{Volume \: of \: Cylinder = \pi r {}^{2} h }}[/tex]

Where ,

π = 3.14

r = radius of cylinder

h = height of cylinder

Solution : -

[tex] \longrightarrow \: \pi r {}^{2} h[/tex]

Now , substituting values of radius and height :

[tex]\longrightarrow \: 3.14 \times (3) {}^{2} \times 5[/tex]

Now , calculating :

[tex] \longrightarrow 3.14 \times 9 \times5 [/tex]

Firstly , multiplying 9 and 5 :

[tex]\longrightarrow \: 3.14 \times 45[/tex]

Atlast , multiplying 3.14 and 45 :

[tex] \longrightarrow \: \bold{ 141.3}[/tex]

[tex] \red{ \boxed{ \rm{Therefore , \: volume \: of \: cylinder \: is \: 141.3 \: ft {}^{3} }}}[/tex]

Answers

Answer: Below

Step-by-step explanation:

Volume is based off of the formula (base × height/depth), with base being (width × length).

We know the three dimensions of the taller box, so:

7.75 × 2 × 12 = 186

The smaller box is 20% shorter. 12 × 0.8 gives us the 0% height, which is 9.6.

7.75 × 2 × 9.6 = 148.8

Since the problem is asking for the difference of the two volumes we do:

186 - 146.8 = 39.2

Our answer is 39.2

The height of the tip of the minute hand of a wall clock is 9 ft. Then the correct option is C.

What is a function?

The function is an expression, rule, or law that defines the relationship between one variable to another variable. Functions are ubiquitous in mathematics and are essential for formulating physical relationships.

The height, h, in feet of the tip of the minute hand of a wall clock as a function of time, t, in minutes can be modeled by the equation

[tex]h =0.75 \cos \left ( \dfrac{\pi}{30(t-15)} \right ) + 8\\[/tex]

When t = 0, then the value of the h will be

[tex]h =0.75 \cos \left ( \dfrac{\pi}{30(0-15)} \right ) + 8\\\\\\h =0.75 \cos \left ( \dfrac{\pi}{-450} \right ) + 8\\\\\\h =0.75 \cos \times 0.9999+ 8\\\\\\h = 0.74998+8\\\\\\h = 8.74889 \approx 9[/tex]
