help me find the value of x!

Answer:

1A: (2,1); (2,4); (6,1); (3,4)

1B: (4,2); (4,8); (12,2); (6,8)

Step-by-step explanation:

1A: It's pretty straightforward-- identify the coordinates for each vertex.

1B: If it's being dilated by a factor of 2, then each vertex is going to be multiplied by a factor of 2. So our vertices would be: (4,2); (4,8); (12,2); (6,8).

Hope this helped!

The coordinates of a point, or points (ABCD) following a dilation about the origin is given by the product of the point and the scale factor of dilation

The description, vertices of the figure, and the new vertices are;

Reason:

1. The quadrilateral is a trapezium

2. The vertices of the quadrilateral are given by the coordinates of the points A, B, C, and D, in the figure, which are;

A(2, 1), B(2, 4), C(3, 4), D(6, 1)

3. Dilating the quadrilateral by a scale factor of two about the origin gives;

Coordinates of A' = (2×2, 2 × 1) = (4, 2)

Coordinates of B' = (2×2, 2 × 4) = (4, 8)

Coordinates of C' = (2×3, 2 × 4) = (6, 8)

Coordinates of D' = (2×6, 2 × 1) = (12, 2)

The new coordinates of the vertices of the quadrilateral following a dilation by a scale factor of two are; (4, 2), (4, 8), (6, 8), and (12, 2)

Answer:

0.42

Step-by-step explanation:

The computation of the length of the remaining rope in inches is shown below:

Length Remaining = Length - the piece he cut off

Length Remaining = 60 - 18

60 - 18 = 42

To turn 42 into a decimal, you have to divide by 100 ↓

42 ÷ 100 = 0.42

The length of rope remaining is 0.42 inches long

Answer:

rational

Step-by-step explanation:

Any rational number can be expressed in the form

[tex]\frac{a}{b}[/tex] ← where a and b are integers

Given

[tex]\sqrt{4}[/tex] = - 2 or + 2

Since - 2 =  [tex]\frac{-2}{1}[/tex] and 2 = [tex]\frac{2}{1}[/tex] ← both in rational form, then

[tex]\sqrt{4}[/tex] is rational

Answer: 1.25 litres

Step-by-step explanation:

Two litres of paint is sufficient to paint  1 ⅗  doors.

To find out the amount of paint needed to paint one door, you can use direct proportion:

2 litres           :              1 ⅗  door

x                                    1 door

Cross multiply to get:

1 ⅗ x = 2

x = 2 /  1 ⅗

x = 2 ÷ 8/5

x = 2 * 5/8

x = 1.25 litres

Answer:

The answer is r = 6a / (5m² - 1).

Step-by-step explanation:

The steps are :

[tex]m = \sqrt{ \frac{6a + r}{5r} } [/tex]

[tex] {m}^{2} = \frac{6a + r}{5r} [/tex]

[tex]5r {m}^{2} = 6a + r[/tex]

[tex]5r {m}^{2} - r = 6a[/tex]

[tex]r(5 {m}^{2} - 1) = 6a[/tex]

[tex]r = \frac{6a}{5 {m}^{2} - 1 } [/tex]

Answer:

r = [tex]\frac{6a}{5m^2-1}[/tex]

Step-by-step explanation:

Given

m = [tex]\sqrt{\frac{6a+r}{5r} }[/tex] ( square both sides )

m² = [tex]\frac{6a+r}{5r}[/tex] ( multiply both sides by 5r )

5rm² = 6a + r ( subtract r from both sides )

5rm² - r = 6a ← factor out r from each term on the left side

r(5m² - 1) = 6a ← divide both sides by (5m² - 1)

r = [tex]\frac{6a}{5m^2-1}[/tex]

You can place approximately 57 DVDs on the shelf if each DVD is 5/8 inches thick. To determine the number of DVDs that can fit on a shelf, we need to divide the length of the shelf by the thickness of each DVD.

The shelf is 36 inches long, and each DVD is 5/8 inches thick.

Dividing the length of the shelf by the thickness of each DVD:

36 inches / (5/8) inches

To divide by a fraction, we multiply by its reciprocal:

36 inches * (8/5 inches)

Simplifying the multiplication:

288 inches / 5 inches

Now we can divide:

288 inches / 5 inches = 57.6

Therefore, you can place approximately 57 DVDs on the shelf if each DVD is 5/8 inches thick.

Answer:

x ≈ 9.5 , y ≈ 15.3

Step-by-step explanation:

sin32° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{x}{18}[/tex] ( multiply both sides by 18 )

18 × sin32° = x , then

x ≈ 9.5 ( to the nearest tenth )

cos32° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{y}{18}[/tex] ( multiply both sides by 18 )

18 × cos32° = y , then

y ≈ 15.3 ( to the nearest tenth )

Answer:

0.9844

Step-by-step explanation:

This is a binomial probability problem.

Probability of getting a correct answer: p = 1/4

Probability of getting an incorrect answer: q = 3/4

Number of questions; n = 3

Thus;

probability of 2 or less correct answers is; P(x ≤ 2) = P(X = 2) + P(X = 1) + P(X = 0)

From binomial probability the formula is;

P(X = x) = C(n, x) × p^(x) × q^(n - x)

P(X = 2) = C(3, 2) × (¼)² × (¾)¹

P(X = 2) = 3 × 0.0625 × 0.75

P(X = 2) = 0.1406

P(X = 1) = C(3, 1) × (¼)¹ × (¾)²

P(X = 1) = 3 × 0.25 × 0.5625

P(X = 1) = 0.4219

P(X = 0) = C(3, 0) × (¼)^(0) × (¾)³

P(X = 0) = 0.4219

P(x ≤ 2) = 0.1406 + 0.4219 + 0.4219

P(x ≤ 2) = 0.9844
