Answer:

Area of triangle = 1/2*b*h

[tex]\frac{1}{2} * 2.8* 7.8\\\frac{1}{2} * 21.84\\\frac{21.84}{2}\\= 10.92[/tex]

Answer:

10.92 cm²

Step-by-step explanation:

The area (A) of a triangle is calculated as

A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )

Here b= 2.8 and h = 7.8 , then

A = [tex]\frac{1}{2}[/tex] × 2.8 × 7.8 = 1.4 × 7.8 = 10.92 cm²

Answer:

41g

Step-by-step explanation:

65.6/8= 8.2g per cake

8.2*5 cakes= 41g

Answer:

Step-by-step explanation:

65.6g = 8 cakes

We need to find the sugar for 1 cake:

65.6 ÷ 8= 8.2 (gram for 1 cake)

The sugar for 5 cakes:

8.2 × 5= 41 (gram for 5 cakes)

Answer:

x = 6, y =3

Step-by-step explanation:

4x-7y=3

x-7y=-15

Multiply the first equation by -1

-4x+7y=-3

Then add this to the second equation to eliminate y

-4x+7y=-3

x-7y=-15

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

-3x +0y = -18

-3x = -18

Divide by -3

-3x/-3 = -18/-3

x = 6

Now find y

x -7y = -15

6 -7y = -15

Subtract 6 from each side

6-7y-6 = -15-6

-7y = -21

Divide by -7

-7y/-7 = -21/-7

y =3

Answer:

  -1

Step-by-step explanation:

Solving the given equation for y, we have ...

  x -y = 18

  y = x - 18 . . . . . add y-18

The coefficient of x is 1. That is the slope of the given line. The desired perpendicular line will have a slope that is the negative reciprocal of this:

  m = -1/1 = -1

The slope of the perpendicular line is -1.

The graph shows you that a line with slope -1 is perpendicular to the given line.

Answer: 15 feets

Step-by-step explanation:

Given that :

Area of square shaped lawn = 224.9 ft²

Measurement closest to side length of the lawn :

Since the length is square shaped ;

Area of square formula = a²; where a = side length of the square

Area = a²

224.9 ft² = a²

Take the square root of both sides

√224.9ft² = √a²

14.996666 ft = a

a = 14.996666 ft

a = 15 ft

Hence, the side length of the lawn is closest to 15 feets

Answer:

255

Step-by-step explanation:

10n^2+5

where n=5

10×5²+5

10×25+5

250+5

255

The 5th term of Sequence is 255.

A sequence is an enumerated group of items in mathematics where repetitions are permitted and order is important. Similar to a set, it has members (also called elements, or terms). The length of the series is the number of elements (potentially infinite).

Given:

10n² +5

Now for 5th term put n= 5 we get

10n² +5

= 10(5)² +5

= 10 x 25 + 5

= 250+ 5

= 255

hence, the 5th term is 255.

The value of x in the expression is 13.

A polygon which has three sides and three vertices is called as triangle.

The sum of all the angles of the triangle is 180°.

Given:

The triangle ABC = triangle DEC,

and angle b=3x and angle e=6x-39.

To find the value of x:

We know,

b = e

So, substituting the values,

3x = 6x - 39

3x = 39

x = 13.

Therefore, the value of x is 13.

Answer:

x - 2 and x - 1 can be possible length and width of the rectangle.

Step-by-step explanation:

Area = x² - 3x + 2

◇◇◇◇◇◇◇◇◇◇◇◇◇◇◇◇◇◇◇

To find possible length and width we can factorize the above expression.

◇◇◇◇◇◇◇◇◇◇◇◇◇◇◇◇◇◇◇◇

x² - 3x + 2 ( 2 = -1 × -2 )

x² - x - 2x + 2 ( 3 = -1 + -2 )

x(x - 1) + -2(x - 1)

(x - 2) (x - 1)

Answer:

18 book copies

Step-by-step explanation:

As you can see, there is a pattern where you add the next number after x. To find where to start, let's subtract the numbers we were given:

6 - 4 = 2

9 - 6 = 3

13 -9 = 4

So our next number is to add 5 to 13: 5 + 13 = 18, so in February the bookstore will order 18 books.
