The diameter of a circle is 4 cm. Find its area to the nearest tenth.

Answer:

x + 2y = 4

Step-by-step explanation:

Line is passing through the points (4,0) and (0, 2)

Slope of line (m) = (2 - 0)/(0-4) = 2/(-4) = - 1/2

y - intercept (b) = 2

Equation of line in slope intercept form is given as:

y = mx + b

Plugging m = - 1/2 and b = 2 in the above equation, we find:

[tex]y = - \frac{1}{2} x + 2 \\ \\ 2y = - x + 4 \\ \\ x + 2y = 4[/tex]

Based on similarity transformation, Since every circle is 360 degrees, so we know that their angles are congruent.

When a figure is transformed by a similarity transformation, an image is created that is similar to the original figure.

The total angle in every circle is 360 degrees, hence all circles are similar.

Thus, we can conclude the following based on similarity transformation, Since every circle is 360 degrees, so we know that their angles are congruent.

Answer:

11.25

Step-by-step explanation:

Ratio of yogurt : ratio of idiot = 1 : 4

Idiot had 45

Yogurt = x

Ratio of yogurt : ratio of idiot = x : 45

Equate the ratios

1 : 4 = x : 45

1/4 = x/45

Cross product

1 * 45 = 4 * x

45 = 4x

x = 45/4

x = 11.25

Yogurt = x = 11.25

Answer:

Greatest angle measure is ∠Q

Smallest angle measure is ∠R

Step-by-step explanation:

As the length of side are in the same order as the measure of the angles opposite the lengths of sides. The greatest side is opposite to the greatest angle.

By using the properties of triangle , if one angle of a triangle is larger than the other angle, then the side opposite to the larger angle is greater than the side opposite to the smaller angle.

Longest side=PR=13cm

∴ Greatest angle measure is ∠Q

Smallest side=PQ=8cm

∴ Smallest angle measure is ∠R

Answer:

Answer:

The angle formed between CF and the plane ABCD is approximately 47.14°

Step-by-step explanation:

The given parameters are;

BC = 6.8

DE = 9.3

∠BAC = 52°

We note that the angles formed by the vertex of a cuboid are right triangles, therefore, by trigonometric ratios, we get;

sin∠BAC = BC/(The length of a line drawn from A to C)

∴ The length of the line drawn from A to C = BC/sin∠BAC

The length of the line drawn from A to C = 6.8/sin(52°) ≈ 8.63

∴ AC = 8.63

By trigonometry, we have;

The angle formed between CF and the plane ABCD = Angle ∠ACF

[tex]tan\angle X = \dfrac{Opposite \ leg \ length}{Adjacent\ leg \ length}[/tex]

[tex]tan\angle ACF = \dfrac{FA}{AC}[/tex]

In a cuboid, FA = BG = CH = DE = 9.3

[tex]\therefore tan\angle ACF = \dfrac{9.3}{8.63}[/tex]

[tex]\therefore \angle ACF = arctan \left(\dfrac{9.3}{8.63} \right) \approx 47.14^{\circ}[/tex]

The angle formed between CF and the plane ABCD = Angle ∠ACF ≈ 47.14°

Answer:

A) 3/56 + 27/56 = 30/56 ÷ 2/2 = 15/28

Step-by-step explanation:

So, there's 3/56 cities that have a lake and 27/56 cities that have a river.

Since the question is asking how much have a lake or river, we add them up.

3/56 + 27/56 = 30/56

(Divide by 2 since that's the common factor)

30/56 ÷ 2/2 = 15/28
