Answer:

x = 35°

Step-by-step explanation:

AC is a straight line with the 3 angles lying on it summing to 180°, so

∠ E + ∠ D + ∠ G = 180°

55° + ∠ D + 90° = 180°

145° + ∠ D = 180° ( subtract 145° from both sides )

∠ D = 35°

then

x  and ∠ D are vertically opposite angles and are congruent, thus

x = 35°

The area of the figure, which has a triangle and a rectangle with the same height, is 275 cm2.

You may also refer to it as a quadrilateral that is equiangular, meaning that all of its angles are equal. The parallelogram could alternatively have a straight angle. Rectangles with four sides that are all the same size are called squares. Four 90-degree vertices and equal parallel sides make up a quadrilateral with the rectangular shape. A rectangle is also referred to as a parallelogram since its opposing sides are parallel and equal.

The value of x in the equation 1.5 (x + 4) - 3 = 4.5 (x - 2) is 4.

The BODMAS rule is a rule used to simplify a mathematical equation. BODMAS itself is an abbreviation of the Bracket, Order, Division, Multiplication, Addition, and Subtraction. This rule indicates the sequence in which a mathematical equation should be solved.

As we want to find the value of x, firstly we have to simplify the equation by applying the BODMAS rule to the given equation:

1.5 (x + 4) - 3 = 4.5 (x - 2)

Since there's no Bracket, Order dan Division part that can be solved, so the first step is applying the Multiply part:

  1.5x + 6 - 3 = 4.5x - 9

Then we apply the addition and subtraction part:

   1.5x - 4.5x = - 9 - 6 + 3

              - 3x = - 12

                  x = 4

Thus, the value of x in the equation 1.5 (x + 4) - 3 = 4.5 (x - 2) is 4.

Answer:

The height is 32

Step-by-step explanation:

The ratio of width to height is

4:3

We know the height is 24  so to go from 3 to 24 is multiplying by 8.

Multiply all terms by 8

4 * 8  : 3 * 8

32: 24

The ratio of the width to height is

32:24

The height is 32

=================================================

Work Shown

width/height = 4/3

w/24 = 4/3

3w = 24*4

3w = 96

w = 96/3

w = 32 cm is the width

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

Another approach.

The ratio of width to height is 4:3, meaning a screen that has width 4 cm and height 3 cm is possible. Instead, we want the "height 3 cm" to be "height 24 cm". This is a jump of "times 8".

Multiply both parts of that ratio by 8 to get...

4:3

8*4:8*3

32:24

A screen that is 32 cm wide and 24 cm tall will give us a ratio 4:3 when simplifying fully.

The order of the numbers is important. We have the width listed first simply because it was listed first in the phrasing "ratio of width to height".

If the perimeter of the isosceles triangle is 12 cm, then the base of the triangle (x), as well as the length of the triangle leg (x) is 4 cm.

An isosceles triangle is a type of triangle in which two sides have the same length. These two equal sides are referred to as the legs of the triangle, while the remaining side is known as the base.

The perimeter of a triangle is the sum of the lengths of all its sides. In this case, since the triangle is isosceles, the base and one leg have the same length (x), and the other leg also has the same length (x). Therefore, the perimeter of the triangle is 2x + x = 3x. Given that the perimeter of the isosceles triangle is 12 cm, then:

3x = 12

 x = 12/3

 x = 4

So, the base and legs of the isosceles triangle each have a length of 4 cm.

Your question seems to be missing the value for the perimeter of the triangle, but I suppose the complete question was:

"The length of the base of an isosceles triangle is x. The length of a leg is x. The perimeter of the triangle is 12 cm. Find x."

Answer:

Perimeter = 162 units

Area = 1508 square units

Step-by-step explanation:

Given expressions:

If x = 10, then:

The formula for the perimeter of a rectangle is:

where w is the width and l is the length.

Therefore, the perimeter of the rectangle is:

[tex]\implies \sf P = 2(29 + 52)[/tex]

[tex]\implies \sf P = 2(81)[/tex]

[tex]\implies \sf P = 162\;units[/tex]

The formula for the area of a rectangle is:

where w is the width and l is the length.

Therefore, the area of the rectangle is:

[tex]\implies \sf A=29 \cdot 52[/tex]

[tex]\implies \sf A=1508\;square\;units[/tex]

Answer:

Area of rectangle = 1508

Perimeter of rectangle = 162

Step-by-step explanation:

Now we have to,

→ find the perimeter and area.

→ where x = 10.

Perimeter of rectangle is,

→ P = 2 × (L + W)

→ P = 2 × (5(10) + 2 + 3(10) - 1)

→ P = 2 × (50 + 2 + 30 - 1)

→ P = 2 × 81

→ [ P = 162 ]

Area of rectangle will be,

→ A = L × W

→ A = (5(10) + 2) × (3(10) - 1)

→ A = (50 + 2) × (30 - 1)

→ A = 52 × 29

→ [ A = 1508 ]

Hence, these are the values.

7 pints of white paint were used to paint her bedroom wall. This is a great way to ensure that the bedroom wall is painted to her desired color scheme with the right amount of blue and white paint.

The total amount of paint used is 9.5 pints.

One fourth of 9.5 pints is 2.375 pints of blue paint.

The remaining amount of paint is 9.5 - 2.375 = 7.125 pints of white paint.

Therefore, 7 pints of white paint were used to paint her bedroom wall.

Ivania used 9.5 pints of blue and white paint to paint her bedroom wall. One fourth of this amount was blue paint, meaning 2.375 pints of blue paint were used. This leaves the remaining amount of paint as 9.5 - 2.375 = 7.125 pints of white paint. Therefore, 7 pints of white paint were used to paint her bedroom wall. This means that the majority of the paint used was white paint, with only a quarter of the paint used being blue.

The value of 20.25 ÷ 0.9 in standard form is 2.25×10¹

The standard form of a number is a way of writing the number in a form that follows certain rules. Any number that can be written as a decimal number, between 1.0 and 10.0, multiplied by a power of 10, is said to be in standard form.

This means that writing a value in the form 35.77× 10³ is very wrong in standard form because 35.77 is less than 10. But instead we write it in the form 3.577×10⁴, now 3.577 is less than 10.

The value of 20.25÷ 0.9 = 22.5

but this is not in standard form because 22.5 is greater than 10. By putting it in standard form, we divide it by 10 and multiply it by 10 again

This means that 22.5 = 2.25×10¹

Therefore 20.25 ÷ 0.9 in standard form is 2.25 × 10¹

The part of the field would Roni mow will be 4 3/7 of the field.

To find out what part of the field Roni would mow if he and Allie worked together to mow the field, you would need to calculate their combined rate of mowing.

You can find the combined rate by adding the rates of each person working alone:

Combined rate = (Roni's rate) + (Allie's rate)

Combined rate = (1/30 hour) + (1/75 hour) = (5/150) + (2/150) = (7/150) hour

Then divide the rate of Roni by the combined rate to find the proportion of the field that Roni would mow:

(Roni's rate) / (Combined rate) = (1/30 hour) / (7/150 hour) = (30/7) / 1 = 4.2857142857142856
