In the above figure, m∠AOC = 26° and m∠BOD = 2x + 32. If ∠AOC and ∠BOD are vertical angles, what is the value of x?

Answers

Answer 1

The value of x is -3.

Step-by-step explanation:

It is given that the angles ∠AOC and ∠BOD are vertical angles.The vertical angles have same measure of angles.Therefore, ∠AOC is equal to ∠BOD.

⇒ 26° = 2x+32

⇒ 2x = 26-32

⇒ 2x = -6

⇒ x = -6/2

⇒ x = -3

Substitute x=-3 in ∠BOD = 2x+32

∠BOD = 2(-3)+32 = 26°

Stefan spent a third of his weekly allowance on clothes. To earn more money his parents let him wash the car for $5. Write and solve a two-step equation to determine his weekly allowance if he ended with $29. *Hint: start with: b/.... +....... =.......

Answers

Answer:

$36

Step-by-step explanation:

The amount spent on cloths is 1/3

The amount earned from washing the car is $5

Amount at the end of the week is $29

Let the amount earned that week be x

Then amount spent on cloths = 1/3x

so the equation is

x- 1/3 x+$5=$29

2/3 x=29-5

2/3 x= 24

x=(24*3)/2= $36

What is the volume of a cone with the height of 5.5 and a radius of 4

Answers

Answer:

29.33π cm³  or 92.10 cm³

Step-by-step explanation:

To find the volume of a cone with height 5.5 and radius 4, we will simply use the formula;

volume of a cone = [tex]\frac{1}{3}[/tex] π r² h

h = 5.5  and r= 4, we will simply plug in these values into our formula

volume of a cone  =  [tex]\frac{1}{3}[/tex]   ×  π   × (4)² (5.5)

                               = [tex]\frac{1}{3}[/tex]  ×π × 16 × 5.5

                                =88π   /  3

                                 =29.33π

volume of cone = 29.33π

But π= 3.14

plugging in π=3.14, we have;

volume of cone = 29.33(3.14)=29.10

a) (30, -19)
b) (31, -20)
c) (32,-22)
What is the answer

Answers

Answer:

C

Step-by-step explanation:

We can solve simultaneous equations using substitution method, elimination method or graphical method. But for this purpose, we will be using the elimination method.

3x+4y=8 Equation 1

2x+y=42 Equation 2

Multiply Equation 1 by 2 and equation 2 by 3, so as to get the same coefficient for x

2(3x+4y=8)= 6x+8y=16 Equation 3

3(2x+y=42)= 6x+3y=126 Equation 4

Subtract equation 4 from 3, to eliminate x

6x-6x=0

8y-3y= 5y

16-126= -110

We now have 5y=-110

Divide both sides by 5,

y= -110/5

= -22

Substituting for y in equation 2

2x+(-22)= 42

2x= 42+22

2x=64

x= 64/2

= 32

Solve this system by elimination: 3x + 2y = 18 5x – 2y = 14

Answers

Answer:

(4,3)

Step-by-step explanation:

3x + 2y = 18

5x – 2y = 14

Add the two equations together to eliminate y

3x + 2y = 18

5x – 2y = 14

------------------------

8x    =   32

Divide each side by 8

8x/8 = 32/8

x = 4

Now determine the value for y

3(4) +2y = 18

12 +2y =18

Subtract 12 from each side

12-12+2y = 18-12

2y = 6

Divide by 2

2y/2 =6/2

y=3

Answer:

x=4 and y=3

Step-by-step explanation:

x+2y=18

Then solve8x=32for x:

You have 42,784 grams of a radioactive kind of curium. If its half-life is 18 years, how much will be left after 72 years?

Answers

Answer:

2,674.14 g

Step-by-step explanation:

Recall that the formula for radioactive decay is

N = N₀ e^(-λt)

where,

N is the amount left at time t

N₀ is the initial amount when t=0, (given as 42,784 g)

λ = coefficient of radioactive decay

  = 0.693 ÷ Half Life

  = 0.693 ÷ 18

  = 0.0385

t = time elapsed (given as 72 years)

e = exponential constant ( approx 2.7183)

If we substitute these into our equation:

N = N₀ e^(-λt)

= (42,787) (2.7183)^[(-0.0385)(72)]

= (42,787) (2.7183)^(-2.7726)

=  (42,787) (0.0625)

= 2,674.14 g

Final answer:

After 72 years, which corresponds to 4 half-lives of the curium with a half-life of 18 years, the remaining amount of a 42,784 gram sample would be 2,674 grams, as it halves every 18 years.

Explanation:

The question asks how much of a radioactive sample of curium, with an initial mass of 42,784 grams and a half-life of 18 years, will remain after 72 years. To answer this, we apply the concept of radioactive decay, which follows a geometric sequence where the quantity of a radioactive substance halves every half-life period.

In this scenario, 72 years consist of 4 half-lives (since 72 ÷ 18 = 4). Therefore, after each half-life, the mass of the curium would be reduced by half. Following the sequence:

After 18 years, half of the 42,784 grams would remain, which is 21,392 grams.

After 36 years, half of that would remain, becoming 10,696 grams.

After 54 years, again half of that would remain, so 5,348 grams.

Finally, after 72 years, halving once more, we would be left with 2,674 grams.

The amount of curium remaining after 72 years is 2,674 grams.

Write and evaluate the expression. Then, check all that apply.

A rectangular poster has an area of 38 square feet. It is 9 1/2 feet wide at its base. What is the height of the poster?

Answers

Final answer:

By using the formula (Area = Length x Width) we can rearrange the equation to find the height of the rectangular poster. It comes out to be 4 feet.

Explanation:

To answer your question, we must use the formula for the area of a rectangle, which is Area = Length x Width. Here, the area of the poster is given as 38 square feet and the width is 9.5 feet. The length is what we're trying to find. We can set this up as an equation 38 = Length x 9.5. To find the Length, we divide both sides of the equation by 9.5 resulting in Length = 38 ÷ 9.5. Solving the equation gives us a length of approximately 4 feet. So, the 'height' of the poster would be 4 feet.
