Complete Question

Triangle ABC has the angle measures shown. Measure of angle A = (2 x) degrees. Measure of angle B = (5 x) degrees. Measure of angle C = (11 x) degrees.

Which statement is true about the angles?

a) Measure of angle A = 20 degrees

b) Measure of angle B = 60 degrees

c) Angle A and Angle B are complementary

d) Measure of angle A + measure of angle C = 100 degrees

Answer:

a) Measure of angle A = 20 degrees

Step-by-step explanation:

It is known that the sum of angles in a triangles = 180°

We are given these values in the question

Triangle ABC has the angle measures shown. Measure of angle A = (2 x) degrees. Measure of angle B = (5 x) degrees. Measure of angle C = (11 x) degrees.

Therefore,

Angle A + Angle B + Angle C = 180°

2x + 5x + 11x = 180°

18x = 180°

x = 180°/ 18

x = 10°

Finding each of the angles

Angle A = 2x = 2 × 10 = 20°

Angle B = 5x = 5 × 10 = 50°

Angle C = 11x = 11 × 10 = 110°

Therefore, the correct option is:

a) Measure of angle A = 20 degrees

The true statement is required.

The true statement is that [tex]m\angle A=10^{\circ}[/tex]

[tex]\angle A=2x[/tex]

[tex]\angle B=5x[/tex]

[tex]\angle C=11x[/tex]

The sum of the angles in a triangle is [tex]180^{\circ}[/tex]

So

[tex]\angle A+\angle B+\angle C=180\\\Rightarrow 2x+5x+11x=180\\\Rightarrow 18x=180\\\Rightarrow x=\dfrac{180}{18}\\\Rightarrow x=10[/tex]

[tex]\angle A=2x=2\times10\\\Rightarrow \angle A=10^{\circ}[/tex]

The true statement is that [tex]m\angle A=10^{\circ}[/tex]

Answer:

p : q : r = 1 : 8/3 : 3/2

Step-by-step explanation:

p/q = (3/4)/2 = 3/(4*2) = 3/8

=> q = (8/3)p

p/r = (1/3)/(1/2) = (1*2)/(3*1) = 2/3

=> r = (3/2)p

=> (p, q ,r) = (p, (8/3)p, (3/2)p)

=> p : q : r = 1 : 8/3 : 3/2

Answer:

First option: As x⇒ ∞ f(x) ⇒ -∞.  As x⇒ -∞ f(x) ⇒ ∞.

Step-by-step explanation:

Rearrange the equation:

f(x) = -x³ - 2x² + 1

This is a negative cubic function. The function decreases over the interval

(-∞, ∞). Therefore:

As x⇒ ∞ f(x) ⇒ -∞.

As x⇒ -∞ f(x) ⇒ ∞.

D.  {3, 5, 7}.

Step-by-step explanation:

The range is the set of output values.

It's {3, 5, 7}.

The range of the set ={1,2,3,4,5} is option D which is {3,5,7}.

The range of a set is the values which are coming when we put the values of a set  in a function.

We are given the diagram in which the values are 1,2,3,4,5 from which arrows touching 3,5,6. So the domain of the function is 1,2,3,4,5 and the range is 3,5,7.

Answer:

Avery needs to pay $14.84

Step-by-step explanation:

When there's a tax we need to sum the original value of the product with the tax's value. To find the amount of money Avery needs to pay in taxes we can apply a rule of three as shown below:

[tex]\frac{14}{x} = \frac{100}{6} \frac{\%}{\%}[/tex]

Where "x" is the tax value, and $14 represents 100%, since it's the value used to calculate the tax. We have:

[tex]x = \frac{14*6}{100}\\x = \frac{84}{100}\\x = 0.84[/tex]

The value to be paid is the product value plus the tax, therefore:

[tex]\text{paid} = 14 + 0.84 = 14.84[/tex]

Avery needs to pay $14.84

Answer:

f(x) = 3.56(2.04)^x

Step-by-step explanation:

Put x as 2, to see whether the output will be close to 16.

116.4 - 42.8 ln(2) = 86.733301

2.04(3.56)^2 = 25.854144

3.56(2.04)^2 = 14.815296

-42.8 + 116.4 ln(2) = 37.882332

Put x as 3, to see whether the output will be close to 30.

116.4 - 42.8 ln(3) =69.379394

2.04(3.56)^3 = 92.040753

3.56(2.04)^3 = 30.223204

-42.8 + 116.4 ln(3) = 85.07847

Put x as 6, to see whether the output will be close to 271.

116.4 - 42.8 ln(6) = 39.712695

2.04(3.56)^6 = 4152.69615

3.56(2.04)^6 = 256.584846

-42.8 + 116.4 ln(6) = 165.760802

Put x as 7, to see whether the output will be close to 522.

116.4 - 42.8 ln(7) = 33.115046

2.04(3.56)^7 = 14783.598295

3.56(2.04)^7 = 523.433085

-42.8 + 116.4 ln(7) = 183.703941

The exponential function that models the data is f(x) = 3.56(2.04)^x.

Answer:

Answer CL  586 cm^2

Step-by-step explanation:

Hello.  It's pi, not pie.

The area of the triangle is A1 = (1/2)(base)(height) = (1/2)(18 cm)(7 cm), or

A1 = 63 cm^2.

The area of the rectangle is A2 = (base)(height) = (18 cm)(22 cm) = 396 cm^2.

The area of the semicircle is A3 = (1/2)(pi)(9 cm)^2 = 3.14(81 cm^2)(1/2) = 127 cm^2

Thus, the total area of the figure is A = 127 cm^2 + 396 cm^2 + 63 cm^2, or

586 cm^2 approximately.

Answer:

V = 4.84 × 10⁷ km³

Step-by-step explanation:

Volume of Sphere = [tex]\frac{4}{3}\pi r^3[/tex]

Where r = 3400 km

V = [tex]\frac{4}{3} (3.14)(3400)^3[/tex]

V = (4)(3.14)(11,560,000)/3

V = 48,422,415 km³

Upto 3 sfs:

V = 4.84 × 10⁷ km³

Answer:

The side length is 2 cm

Step-by-step explanation:

The volume of a cube is s^3

V = s^3

8 = s^3

Take the cube root of each side

8 ^ 1/3 = s^3 ^ 1/3

2 = s

The side length is 2 cm

Answer:

2 cm

Step-by-step explanation:

The volume of a cube can be found using the following formula:

V=s^3

where s is the length of one side. We know the volume is 8 cm^3, therefore we can substitute that value in for V.

8 cm^3=s^3

We want to find what the side length is. The side length is being cubed. The inverse of a cube is the cube root. Therefore, we must take the cube root of both sides, or raise both sides to the power of 1/3.

(8 cm^3)^1/3=(s^3)^1/3

(8 cm^3)^1/3=s

2 cm=s

The length of one side is 2 centimeters.

Answer:

-3/2

Step-by-step explanation:

With perpendicular lines, the slope switches to its reciprocal and and positive/negative sign switches, i.e, the 2/3 will switch to 3/2 and since the original is positive, the new slope will be negative

Answer:

Slope is -3/2

Step-by-step explanation:

The slope of line that is perpendicular to the line should have a slope that is a negative reciprocal of this slope and multiplying both slopes give us -1

=> The slope of this line is 2/3

=> The slope of line perpendicular to it would be -3/2

Multiplying the two slopes:

=> (2/3)*(-3/2)

=> -1

Area of equilateral triangle  A = 24.22 cm²

Step-by-step explanation:

Step(i):-

Perimeter of equilateral triangle  = 3 a

Given  Perimeter of equilateral triangle  = 22.45 cm

   now   3 a = 22.45

  Dividing '3' on both sides,we get

             a = 7.48 cm

Step(ii):-

Area of equilateral triangle

                                  [tex]A = \frac{\sqrt{3} a^{2} }{4}[/tex]

                                   [tex]A = \frac{\sqrt{3} (7.48)^{2} }{4}[/tex]

                                  A = 24.22 cm²

Answer:

m∠A = 166°

Step-by-step explanation:

∠B and ∠A are corresponding angles because the two lines are congruent. Therefore:

7x + 40 = 3x + 112

Subtract 3x from both sides:

4x + 40 = 112

Subtract 40 from both sides:

4x = 72

Divide both sides by 4:

x = 18

Plug this in for ∠A:

∠A = 7 (18) + 40

m∠A = 166°

Answer: 192 in²

Step-by-step explanation:

The area of a rectangle is to multiply the length and the width, or the base and height. Since we are given the base and the height, we can multiply them to find the area. Since the units are different between the height and base, we need to make sure to have the height be 48 in.

A=4×48=192 in²

Answer:

y≤ 2/3x+1/5

Step-by-step explanation:

y≤ 2/3x+1/5

Answer:

x = 116°

y = 90°

Step-by-step explanation:

∠F = 90°, so arc EDS = 180°.

Therefore, arc EFS = 360° − 180° = 180°.  Which means ∠D = 90°.

Angles of a quadrilateral add up to 360°, so:

x + 90° + 90° + 64° = 360°

x = 116°

Answer:

The value of x is 116° and y = 90°

Step-by-step explanation:

Given that opposite supplementary angles in a cyclic quadrilateral is 180° :

[tex]x + 64 = 180 \\ x = 180 - 64 \\ x = 116[/tex]

[tex]y + 90 = 180 \\ y = 180 - 90 \\ y = 90[/tex]

Correct question is;

A bag contains 10 counters. 6 of them are white. A counter is taken at random and not replaced. A second counter is taken out of the bag at random. Calculate the probability that only one of the two counters are white

Answer:

probability that only one of the two counters is white = 8/15

Step-by-step explanation:

To solve this question, first of all, let's look at probability we would have to either draw two white counters or two non-white counters (4/10 * 3/9).

Probability(draw 2 white counters) = (6/10 × 5/9) = 30/90 = 1/3

Probability(draw 2 non-white counters) = (4/10 × 3/9) = 2/15

Now, In all other cases, we'll draw exactly one white and one non-white counter, so the odds of this would be;

P(one white counter and one non-white counter) = 1 - [1/3 + 2/15)

= 1 - 7/15 = 8/15
