Answer:

17=s+7

-7    -7

-----------

10    0

s=10

Step-by-step explanation:

-Subtract 7 from both sides

-Remove the 0 and the addition sign

-You are now left with the equation s = 10

-Once you check to make sure 10 + 7 = 17 you have your answer

The statement which says that the measure of ∠ABD = ¹/₂ ∠ABC. So, the correct option is C.

An angle bisector is defined as a ray, segment, or line that bisects a given angle into two equal angles. The word bisection or half means dividing one object into two equal or identical parts. In geometry, we usually divide triangles and angles by lines or lines that are considered bisectors.

A geometric bisector is a ray, line, or segment that divides a given angle into two equal parts. For example, the bisector of a 60 degree angle divides it into two 30 degree angles. In other words, split the angle into two smaller congruent angles.

For the given case,

Ray BD bisects ∠ABC into two equal angles ∠ABD and ∠DBC; which can be written as ∠ABD = ¹/₂ ∠ABC.

Answer:

3 batches

Step-by-step explanation:

Given that :

Let Number of batches of cupcakes made = x

12 eggs was used to make x batches

Number of eggs used per batch = 4

If 4 eggs was used for a batch :

Number of batches of cupcakes made :

12 eggs / 4 eggs

= 3 batches

answer : is 0.6 Tablespoon

step : 20 rolls = 5 tablespoon

5 rolls = 1 tablespoon

1tablespoon ÷ 5 rolls = 0.2 Tablespoon

0.2 x 3 Rolls = 0.6 Tablespoon

We know that,

[tex]\bigstar \: \boxed{\sf {Area_{(Circle)} = \pi r^2}} \\ [/tex]

[tex] \sf \longmapsto {Area = \{3 \times (32)^2 \} \: m^2 } [/tex]

[tex] \sf \longmapsto {Area = \{3 \times 1024 \} \: m^2 } [/tex]

[tex] \longmapsto \sf \red {Area = 3072 \: m^2 } [/tex]

Therefore,

X=49°

Step-by-step explanation:

we have an isosceles triangle

thus our equation is

x+x+82=180°

=>2x+82°=180°

cancel 82 from both sides

=>2x=98

divide both sides by 2

therefore

X=49

Answer:

The speed is 900,000,000 km/h

Step-by-step explanation:

The ratio of distance covered to time taken gives the speed of an object

[tex]Speed, \ v = \dfrac{Distance, \ d}{Time, \ t}[/tex]

Given that the distance covered, d = 5 × 10⁵ cm

The time to travel the given distance, t = 2 × 10⁻⁵ seconds

Therefore;

[tex]Speed, \ v = \dfrac{5 \times 10^{5} \ cm}{2 \times 10^{-5} \ s} = 2.5 \times 10 ^{10} \ cm/s[/tex]

In km/h, we have;

1 cm = 0.00001 km

∴ v = 2.5 × 10¹⁰ cm/s × 1 km/(100,000 cm) × 3,600 s/h = 900,000,000 km/h

The speed is 2.5 × 10¹⁰ cm/s or 900,000,000 km/h.

Answer:

Angle of elevation from the duck is [tex]59.7^{o}[/tex]

Step-by-step explanation:

This description can be represented by the three sides of a triangle and the given angle. Let the angle required be represented by θ. Thus applying the appropriate trigonometric function, we have;

Tan θ = [tex]\frac{opposite}{adjacent}[/tex]

So that,

Tan θ = [tex]\frac{12}{7}[/tex]

          = 1.7143

θ = [tex]Tan^{-1}[/tex] 1.7143

  = 59.7438

θ = [tex]59.7^{o}[/tex]

The angle of elevation from the duck is determined as [tex]59.7^{o}[/tex].

Answer:

  C.  25°

Step-by-step explanation:

A useful relation for this geometry is "an exterior angle of a triangle is equal to the sum of the remote interior angles." The measure of arc BC is the same as the measure of central angle BDC, which is an exterior angle of triangle ACD.

__

Triangle ACD has sides AD and CD that are radii of the circle, so it is an isosceles triangle with angle A ≅ angle C. Exterior angle BDC is the sum of those congruent angles:

  ∠BDC = ∠CAD +∠ACD

  50° = 2×∠ACD

  25° = ∠ACD . . . . . . . . divide by 2

Answer:

B

Step-by-step explanation:

You find the multiplicity by looking at the power of the original root. You can imagine it as [tex](x+7)^1(x+3)^2[/tex]. Now set those equal to 0 to find the value of them as roots.

[tex]x+7=0\\x+3=0[/tex]

Solve them both and you get:

[tex]x=-7\\x=-3[/tex]

Now as we saw in the origin of the roots above that (x + 7) was raised to the first power. That means it has a multiplicity of one, which also means it crosses when it reaches the x-axis. (x + 3) however had a multiplicity of 2, since it was squared. That means that (x + 3) will touch and turn the x-axis.

Therefore the answer is B since that agrees with everything we said.

Slope = -1

Step-by-step explanation:

Since, slope of a line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by,

Slope = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

Therefore, slope of a line passing through two points A(1, 4) and B(3, 2) will be,

Slope = [tex]\frac{4-2}{1-3}[/tex]

          = (-1)

Therefore, slope of the line is (-1).
