The length of line WX in both rectangles  is 10.5 ft. The right option is (D) 10.5.

What is a rectangle?

A rectangle is a plane shape with fours sides, having two opposite sides equal and parallel.

To calculate the length of WX, we use the formula below.

Note: Rectangle RSTV is similar to rectanngle WXYZ. And the ratio of their corresponding Lengths are equal.

Formula:

RV/WZ = RS/WX.................. Equation 1

From the question,

Given:

RV = 2 ftWZ = 5 ftRS = 4.2 ft

Substitute these values into equation 1 and solve for WX

2/5 = 4.2/WXWX = (5×4.2)/2WX = 10.5 ft

Step-by-step explanation:

5375/42 = 128 (округляем)

Answer:

128 days

Step-by-step explanation:

To solve this problem, we simply have to divide the total amount of oil in the tank by the amount of oil used each day.

[tex]5375 \textrm{ liters} \times \dfrac{1 \textrm{ day}}{42 \textrm{ liters}} = \dfrac{5375}{42} \textrm{ days} \approx 128 \textrm{ days}[/tex]

So, the tank will be empty after 128 days.

Note that the number of days is approximate; normally when measuring in the real world, whole numbers are used, as decimals in certain contexts (like in this situation) are confusing. So to simplify our answer, we can simply round up to 128 because by the end of the 128th day, the tank will be empty.

20.25 ➗ 0.9 standard form

Answers

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

What is standard form?

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

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

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

Answers

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.

The Ratio Of A Screen's Width to it's height is 4:3.
The height of the screen is 24 cm.
What is it's width in centimetres (cm)?

Answers

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

Answer:  32 cm

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

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".

A rectangle has a length of 5x+2 and a width of 3x - 1. If x=10, what is the perimeter and area?

Answers

Answer:

Perimeter = 162 units

Area = 1508 square units

Step-by-step explanation:

Given expressions:

Length = 5x + 2Width = 3x - 1

If x = 10, then:

Length = 5(10) + 2 = 52Width = 3(10) - 1 = 29

The formula for the perimeter of a rectangle is:

P = 2(w + l)

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:

A = w · l

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.

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

Kara is building a sandbox shaped like a kite for her nephew. The top two sides of the sandbox are 29 inches long. The bottom two sides are 25 inches long. The diagonal DB has a length of 49 inches. What is the length of the diagonal AC

Answers

The length of diagonal AC is 54.8 inches when two sides are 29inches and 25 inches long.

How is this determined?

To find the length of diagonal AC in the kite-shaped sandbox, we can use the Pythagorean Theorem. The Pythagorean Theorem states that in a right triangle, the length of the hypotenuse (the longest side) is equal to the square root of the sum of the squares of the other two sides.

How to use the Pythagorean Theorem?

Identify the right triangle. In this case, we can see that the right triangle is formed by diagonal DB and the two sides of length 25 inches, which we'll call side a.

Substitute the known values into the formula, where AC is the hypotenuse and a and DB are the other two sides of the triangle: AC^2 = a^2 + DB^2

Solve for AC by taking the square root of both sides: AC = √(a^2 + DB^2)

Substitute the given values for a and DB: AC = √(25^2 + 49^2) = √(625 + 2401) = √3016 = 54.8

It's important to note that the kite shape can be considered as two congruent right triangles. The sides 25 and 29 are the legs, and the diagonal DB (49 inches) is the hypotenuse of one of the triangles. Since the triangles are congruent, their hypotenuse will have the same length. Therefore, the diagonal AC, which is the hypotenuse of the other triangle, also has a length of 49 inches.

Answers

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

How to calculate the fraction?

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

So Roni would mow about 4.29 or roughly 4.3/7 of the field if he and Allie worked together.

slope = (33.50- 22)/ (1-0)

slope = 11.5

So, the Equation for Manuel

y- 22= 11.5 (x- 0)

y- 22 = 11.5x

y= 11.5x + 22

Ruben:

slope = (205- 218)/ (1-0)

slope = - 13

So, the Equation for Ruben

y- 218= -13 (x- 0)

y- 218 = -13x

y= -13x + 218

What is the algebraic expression?

An algebraic expression is a mathematical phrase that can contain numbers, variables, and mathematical operations. It represents a mathematical relationship, but it does not have a specific value. Algebraic expressions can be simple or complex, and they can be used to represent mathematical concepts or to perform calculations.

Here,

To find the value of 3b - 5c when b = 5 and c = 2, we can substitute these values into the expression and simplify it.

Given 3b - 5c = 3(5) - 5(2) = 15 - 10 = 5

Hence, the value of 3b - 5c when b = 5 and c = 2 is 5
