Answer:

So area of square is: a^2

5^2=25cm^2

4/9 x 25 = 100/9

Area of picture is: 11.11 cm^2

Step-by-step explanation:

The area of the square will be equal to 11.11 square centimetres.

The space covered by the two-dimensional object on a plane is called as an area. The space covered by the square in a two-dimensional plane is called the area of the square.

The square is a quadrilateral having four sides and all the sides of the square are equal to each other.

The the area of the square is calculated as,

a² = 5²=25 cm²

The picture area is 4/9 of the total

area.

4/9 x 25 = 100/9

The area of the picture is: 11.11 cm²

Answer/Step-by-step explanation:

✔️m<1 + 52° = 180° (consecutive angles angle)

m<1 = 180 - 52

m<1 = 128°

✔️m<2 = 52° (alternate interior angles are congruent)

✔️m<3 = 47° (alternate interior angles are always equal)

✔️m<4 + 47° = 180° (consecutive angles)

m<7 = 180 - 47

m<7 = 133°

✔️m<5 = 180 - (52 + 47)

m<5 = 180 - 99

m<5 = 81°

Answer:

A quadratic equation is some thing like

(x+2)^2

or

(x+2)(x+5)

In order to solve them, the most basic method is the FOIL method

F-First

O-Outside

I-Inner

L-Last

So for example

(x+2)^2

Which is basically

(x+2)(x+2)

So the first is the 2 Xs

(x+2)(x+2)

x*x=x^2

The outer is the x and the 2,

(x+2)(x+2)

2*x=2x

Now the Inner which is the 2 and the x

(x+2)(x+2)

2*x=2x

And finally the last  which is the 2 and the second 2

(x+2)(x+2)

2*2=4

Now add them all up

X^2+2x+2x+4

Combine like terms

x^2+4x+4

There you have it

Do the same with every other quadratic equation

Answer:

A = 16cm

B = 32cm

C = 8cm

D = Sorry the time I learned this I didn't learn it for fractions.

There are two other important distances on a circle, the radius (r) and the diameter (d). The radius, the diameter, and the circumference are the three defining aspects of every circle. Given the radius or diameter and pie you can calculate the circumference.

The diameter is the distance from one side of the circle to the other at its widest points. The diameter will always pass through the center of the circle. The radius is half of this distance.

The formula for working out the circumference of a circle is:

Circumference of circle = π x Diameter of circle

This is typically written as C = πd.

All the angles make a full circle which needs to equal 360 degrees.

Add all the angles together to equal 360:

X + (x-10) + (4x-20) +(2x-10) + (x +10) = 360

Combine like terms:

9x -30 = 360

Add 30 to both sides:

9x = 390

Divide both sides by 9:

X = 390/9

X = 43.3333. ( 43 and 1/3)

Answer:

x = 43 1/3 degrees.

Step-by-step explanation:

All these angles add up to 360 degrees , so we have:

x - 10 + 4x - 20 + 2x - 10 + x + 10 + x = 360

9x - 30 = 360

9x = 390

x = 390/9

= 43 1/3 degrees

DE = 14

Step-by-step explanation:

Since, DE is a Mid-segment of triangle ABC.

Therefore,

DE = 1/2 * AC

2 DE = AC

2(5x - 1) = 3x + 19

10x - 2 = 3x + 19

10x - 3x = 19 +2

7x = 21

x = 21/7

x = 3

DE = 5x - 1

DE = 5*3 - 1

DE = 15 - 1

DE = 14

Answer:

The fourth graph i.e. RIGHT BOTTOM GRAPH is correct which represents the proportional relationship given by the rule y = 3x.

Also, the correct graph is attached below.

Step-by-step explanation:

Given the rule

''y is 3 times the value of x".

It means

y = 3x

comparing with the slope-intercept form of the line equation

y = mx+b

where y is the slope and b is the intercept

so,

The slope of y = 3x will be: m = 3

The y-intercept of  y = 3x will be: b = 0

CHECKING THE 4TH GRAPH (THE RIGHT BOTTOM SIDE)

Taking two points

(0, 0)

(2, 6)

Finding the slope between (0, 0) and (2, 6)

Using the formula

Slope = m =  [y₂ - y₁] /  [x₂ - x₁]

                =  [6 - 0] / [2 - 0]

                = 6 / 2

               = 3

Thus, the slope of the line = m = 3

We know that the value of y-intercept can be determined by setting x = 0, and determining the corresponding value of y.

From the graph, it is clear

at x = 0, y = 0

Thus, the y-intercept b = 0

Now, substituting m = 3 and b = 0 in the slope-intercept form of linear function

y = mx+b

y = 3x+0

y = 3x

Therefore, the fourth graph i.e. RIGHT BOTTOM GRAPH is correct which represents the proportional relationship given by the rule y = 3x.

Also, the correct graph is attached below.

It's the bottom right graph.

Answer:28 dollar

Step-by-step explanation: 140 x (20/100)= 28 dollar

140-28= 112 the price after the sale

Answer: you will save $28.

Step-by-step explanation:

To find a percent of a number you have to turn the percent into a decimal. For example you would turn 20% into 0.20 then multiply this by 140. After doing this you will find out that 20% of 140 is 28.

Answer:

(a) and (d) will be done by regrouping

Step-by-step explanation:

Solution will be done by regrouping if unit term of term which is subtracted is greater then the term which subtracts.

(a) 65 -56, since the unit term of 65 is 5 and of 56 is 6

as the unit terms of 56 is greater than unit term of 65

Thus solution will be done by regrouping

⇒ 65 -56 = 9

(b) 28 -15, since the unit term of 28 is 8 and of 15 is 5

as the unit terms of 28 is greater than unit term of 15

Thus solution will not be done by regrouping

⇒ 28 -15 = 13

(c) 16 -6, since the unit term of 16 is 6 and of 6 is 6

as the unit terms of 16 is equal to unit term of 6

Thus solution will not be done by regrouping

⇒ 16 -6 = 10

(d) 74-38 , since the unit term of 74 is 4 and of 38 is 8

as the unit terms of 38 is greater than unit term of 74

Thus solution will be done by regrouping

⇒ 74-38 = 36

Answer:

d = 1

t = 16

Step-by-step explanation:

Television = t

DVD = d

4t + 6d = 70

2t + 5d = 37

2t + 5d = 37

2t = 37 - 5d

2t/2 = 37/2 - 5d/2

t = 18.5 - 5/2d

4t + 6d = 70

4(18.5 - 5/2d) + 6d = 70

74 - 10d + 6d = 70

-4d = -74 + 70

-4d = -4

-4d/-4 = -4/-4

d = 1

2t + 5d = 37

2t + 5(1) = 37

2t + 5 = 37

2t = 37 - 5

2t = 32

2t/2 = 32/2

t = 16

Check: d = 1; t = 16

4t + 6d = 70

4(16) + 6(1) = 70

64 + 6 = 70

70 = 70

2t + 5d = 37

2(16) + 5(1) = 37

32 + 5 = 37

37 = 37
