The Value of the equation is 19.

A linear equation is a type of equation in which every variable's degree is exactly one. In one-variable linear equations, there is only one possible solution to the equation and there is only one variable. It appears to be a straight line, either horizontally or vertically, when it is drawn on a graph.

Given equation 3m - 2

and m = 7

substitute the value of m in the equation,

3 x 7 - 2

21 - 2 = 19

Hence the value is 19.

The independent quantity is time and the dependent quantity is T-shirt printed

Step-by-step explanation:

We are asked to determine the dependent and independent quantity.

An independent quantity is a quantity that is not dependent on other quantities while a dependent quantity is a quantity that depends on other quantity. In the the question, the number of T-shirts being made depends on the amount of time the machine works making 3 T shirts per minute, this means that the number of T-shirts made is dependent on the time.

The independent quantity is time and the dependent quantity is T-shirt

Answer:

Step-by-step explanation:

Total number of ice cream invented for customers to try = 25 new flavours

Amount of least popular flavors  thrown out = 13 flavors

Remaining flavor nit thrown out = Total ice cream invented - amount thrown out = 25 - 13

= 12 flavors

The remaining number flavors that was produced is 12 flavors.

If 80 cartons of each of the remaining flavor was made, the total amount of cartons made = 12* 80 = 960 cartons.

Since 2 cartons contains 1 litre

960 cartons will contains (960*1/2) litres

Hence 960 cartons will contain 480litres of the ice cream.

This shows that there are total of 480 litres of ice cream in the cartons

Work Shown:

x = central angle = 255 degrees

r = radius = 4

A = area of sector

A = (x/360)*pi*r^2 ... see note below

A = (255/360)*pi*4^2

A = 34pi/3

note: the formula only works if the central angle x is in degrees. If x is in radians, then use the formula A = (x/2)*r^2

Answer:

The dimensions are 50 yards by 98 yards

Step-by-step explanation:

If the width is w, then the length is 2w - 2. Perimeter can be expressed by 2 * (length + width), therefore:

2 * (2w - 2 + w) = 296

2 * (3w - 2) = 296

3w - 2 = 148

3w = 150

w = 50 so 2w - 2 = 2 * 50 - 2 = 98

Answer:

[tex]\Large \boxed{\mathrm{98 \ yards \cdot 50 \ yards}}[/tex]

Step-by-step explanation:

Let the length be l.

Let the width be w.

[tex]l = 2w - 2[/tex]

The perimeter of the rectangle is 296 yards.

[tex]P = 2l + 2w[/tex]

Plug in the value for l and P.

[tex]296 = 2(2w-2) + 2w[/tex]

Evaluate and solve for w.

[tex]296 = 4w - 4 + 2w \\\\296 = 6w - 4 \\\\300 = 6w \\\\50 = w[/tex]

The width is 50 yards.

Let w = 50 for l.

Evaluate and solve for l.

[tex]l = 2(50) - 2 \\ \\ l = 100 - 2 \\\\l = 98[/tex]

The length is 98 yards.

Answer:

  (2, 5)

Step-by-step explanation:

A 90° CCW transformation is ...

  (x, y) ⇒ (-y, x)

For A(5, -2), the image point is A'(2, 5).

_____

In your mind, draw a line segment from the origin to point A. You will see that is slope is (rise)/(run) = -2/5.

When you rotate that segment 90° CCW about the origin, it will extend into the first quadrant. The rotated segment is perpendicular to the one you started with, so its slope is ...

  -1/(-2/5) = 5/2

That is, it will have a rise of 5 for a run of 2. The point A' will have a x-coordinate of 2 (the run), and a y-coordinate of 5 (the rise).

  A'(2, 5)

Answer:

Step-by-step explanation:

Given  sin²∅ + sin∅ = 1, we are to find the value of  sin²∅ + sin⁴∅. ... 2

From  sin²∅ + sin∅. = 1;  sin²∅ = 1 - sin∅. ... 3

Substitute equation 3 into 1

sin²∅ + sin⁴∅

=  sin²∅ + (sin²∅)²

=  (1 - sin∅)+( 1 - sin∅)²

open the parenthesis

= 1 - sin∅+ (1-2sin∅+ sin²∅)

= 1 - sin∅+ 1-2sin∅+ sin²∅

= 1+1-sin∅-2sin∅+sin²∅

= 2 - 3sin∅+sin²∅

Since sin²∅ = 1 - sin∅, the resulting equation becomes;

= 2 - 3sin∅+(1 - sin∅)

= 2 - 3sin∅+1-sin∅

= 3-4sin∅

Answer:

[tex]\huge\boxed{The\ length\ of\ Diagonal = 61 \ m}[/tex]

Step-by-step explanation:

Length = 50 m

Width = 35 m

Using Pythagorean Theorem:

[tex]c^2 = a^2 + b^2[/tex]

Where c = diagonal , a = length (50 m) and b = width (35 m)

=> [tex]c^2 = 50^2+35^2[/tex]

=> [tex]c^2 = 2500 + 1225[/tex]

=> [tex]c^2 = 3725[/tex]

Taking sqrt on both sides

=> c = 61 m

The length of Diagonal = 61 m.

Step-by-step explanation:

a squared +b squared= c squared

where c is the hypotenuse

35^2+50^2=c^2

1225+2500=c^2

3725=c^2

c^2=61.0328

Answer:

3/4

Step-by-step explanation:

open the brackets by multiplication

12x+28= 19

12x= 19-28

12x= -9 (divide)

-9/12x

x= 3/4

Answer:

[tex]\boxed{x=-0.75 }[/tex]

Step-by-step explanation:

4 ( 3x + 7 ) = 19

→ Expand the brackets

12x + 28 = 19

→ Minus 28 from both sides to isolate 12x

12x = -9

→ Divide 12 from both sides to isolate x

[tex]x=-\frac{9}{12} =- \frac{3}{4} =-0.75[/tex]

Answer: 100

Step-by-step explanation:

You know that AB is || to CD, angle BAC ≅ ACD  (this is the theorem where a line connecting the diagnose of two parallel line, the alternative interior angles are equal/ congruent)

You know that EF is || to BC, angle DHF ≅ GHC (these two are  vertically opposite angle which are equal/ this is a theorem)

-------------------------------------------------------------------------

we now know the angles in ΔGHC where angle GHC=35, angle GCH=65, and angle CGH=80 (subtract other angles from 180)

angle AGH is supplementary w=angle with CGH, which means we subtract 80 from 180, we get 100 will be the angle of AGH

( a ) The value 1200 in this content represents the starting value, or the number of bacteria that was present in the beginning.

( b ) 1.8 represents the growth factor, or by how much more the bacteria increases, in multiples of the quantity.

( c ) As you can tell 1000 has a similar function as 1200, it models the number of bacteria present in the beginning. The difference between the studies is that the second study is present with a starting value of 1000 yet a similar growth factor, and hence will always have a smaller number of bacteria after t hours.

Answer:

acute angle

Step-by-step explanation:

acute = less than 90 degrees

right = exactly 90 degrees

obtuse = more than 90 degrees

90 divided by 2 = 45

45 is less than 90 so acute angle

1/2 of a right angle is called an acute angle. The correct answer would be an option (D).

When two lines intersect at a location, vertical angles are generated. They are always equal to each other.

An angle with a measure of 1/2(90°) : 45°

As per the given question, the required solution would be as:

Straight: An angle with a measure of exactly 180° is considered straight. 45° is not a straight angle.

Obtuse: An angle with a measure greater than 90° and less than 180° is considered obtuse. 45° is not an obtuse angle.

Acute: An angle with a measure less than 90° is considered acute. 45° is an acute angle.

Thus, 1/2 of a right angle is called an acute angle.

Answer:

Step-by-step explanation:

6

Answer:

Step-by-step explanation:

Pythagorean theorem: In a right angle triangle, the square of hypotenuse is equal to the sum of squares of other two sides

BC² + AB² = AC²

5² + AB² = 13²

25 + AB² = 169

        AB² = 169 - 25

        AB² = 144

       AB = √144 = √12*12

AB = 12cm
