Step-by-step explanation:

~~~~~~~~~~~~~~~

QUESTION 1: B

Half of a circle is 180. One side is 27° and the one in the middle is a right angle which is 90°. So we must add the sides together than subtract them by 180°.

                                                90° + 27° = 117°

                                               180° - 117° = 63°

So now we know that angle A is 63°!

Angle C is adjacent to angle A making it 63° as well. We also know that angle B is adjacent so that means angle B is 117°.

Only B is is the correct answer.

~~~~~~~~~~

QUESTION 2: x = 20

150° is adjacent to 7x + 10 making them equal. But how do we solve this? We must make a linear equation out of this!

                                              150 = 7x + 10

Subtract 10 on each side,

                                              150 = 7x + 10

                                              - 10          - 10

We get,

                                               140 = 7x

Divide by 7 on each side,

                                          140 ÷ 7 = 7x ÷ 7

Evaluate,

                                                  20 = x

We get that our answer is x = 20!

~~~~~~~~~~~~~~~~~~

QUESTION 3: x = 21.8°

We know that x° + 68.2° = 90° or a right angle. Therefore for this problem we must subtract!

90° - 68.2° = 21.8°

For this question x is 21.8°

~~~~~~~~~~~~~~~~~~~~~

QUESTION 4:

For this question we know that 4x + 8x = 180° we must solve this linear equation out!

                                             4x + 8x = 180°

Add,

                                                   12x = 180°

Divide by 12,

                                           12x ÷ 12 = 180° ÷ 12

Evaluate,

                                                      x = 15

We now know that x = 15 which solves our 4th and final question of the day! Phew! That took a lot of brain power but we made it! Nice job everyone!

Answer:

1) d. All of the above are true

2) b. 21.8°

3) 7x + 10 = 150 ; x = 20°

4) b. The measure of angle B is 117°

Step-by-step explanation:

1) 4x + 8x = 180

12x = 180

x = 15°

4x = 60°

8x = 120°

2) x = 90 - 68.2

x = 21.8°

3) 7x + 10 = 150

(Vertically opposite angles)

7x = 140

x = 20°

4) Angle A = 180 - 90 - 27

Angle A = 63°

Angle B = 180 - 63

Angle B = 117°

Angle C = 180 - 117

Angle C = 63°

Answer:

D. 1,019 square feet

Step-by-step explanation:

10x13x8 - 3x7

John will need to paint 347 square feet of wall in his rectangular basement after subtracting the area of the door that will not be painted.

John will paint the four walls of his rectangular basement. To calculate how many square feet of wall he will need to paint, we must first determine the total area of the walls and then subtract the area of the door.

The total wall area is calculated as follows:

Two walls are 10 feet long and 8 feet high, giving 2 x (10 x 8) = 160 square feet.

The other two walls are 13 feet wide and 8 feet high, giving 2 x (13 x 8) = 208 square feet.

So, the total wall area is 160 + 208 = 368 square feet.

The door measures 3 feet by 7 feet, which equals 21 square feet.

To find the area John will paint, we subtract the area of the door from the total wall area:

368 square feet - 21 square feet = 347 square feet

Therefore, John will need to paint 347 square feet of wall.

Answer:

8.6 grams of the substance remains after 30 years.

The amount of the substance will drop to below 20 grams in 14 years.

Step-by-step explanation:

The amount of the substance after t years is given by the following equation:

[tex]A(t) = A(0)(1-r)^{t}[/tex]

In which A(0) is the initial amount and r is the yearly decay rate.

A radioactive element decays at a rate of 5% annually. There are 40 grams of the substance present.

This means, respectively, that [tex]r = 0.05, A(0) = 40[/tex]

So

[tex]A(t) = A(0)(1-r)^{t}[/tex]

[tex]A(t) = 40(0.95)^{t}[/tex]

How much of the substance remains after 30 years (to the nearest tenth)?

This is A(30).

[tex]A(30) = 40(0.95)^{30} = 8.6[/tex]

8.6 grams of the substance remains after 30 years

When will the amount of the substance drop to below 20 grams (to the nearest year)?

This is t when A(t) = 20. So

[tex]A(t) = 40(0.95)^{t}[/tex]

[tex]20 = 40(0.95)^{t}[/tex]

[tex](0.95)^{t} = \frac{20}{40}[/tex]

[tex](0.95)^{t} = 0.5[/tex]

[tex]\log{(0.95)^{t}} = \log{0.5}[/tex]

[tex]t\log{0.95} = \log{0.5}[/tex]

[tex]t = \frac{\log{0.5}}{\log{0.95}}[/tex]

[tex]t = 13.51[/tex]

Rounding to the nearest year

The amount of the substance will drop to below 20 grams in 14 years.

1) The amount of substance that will remain after 30 years is; A(30) = 8.6 g

2) The time when the amount of the substance drop to below 20 grams is; t < 14 years

A(t) = A_o(e^(-rt))

Where;

A_o is initial amount

r is rate of decay

t is time in years

A(t) is amount left after t years

We are given;

A_o = 40 g

r = 5% = 0.05

1) To find the amount of substance left after 30 years is;

A(30) = 40 × e^(-0.05 × 30)

A(30) = 8.925 g

Approximating to the nearest tenth gives;

A(30) = 8.9 g

2) To find the time when the amount of the substance drop to below 20 grams.

20 > 40 × e^(-0.05 × t)

20/40 > e^(-0.05 × t)

-0.05t < In 0.5

t < (In 0.5)/-0.05

t < 13.86 years

Approximating to the nearest year gives;

t < 14 years

Answer: P(A∪B)=0.72. The answer is provided below.

Step-by-step explanation:

Sue travels by bus or walks whenever she goes to the shops.

Probability of (catching the bus to shop ), P(A)= 0.4

Probability of (catching the bus from the shop ), P(B) = 0.7

Both of the events A and B are independent events.

Therefore, P(A∩B) = 0.4 × 0.7

 = 0.28

Probability that Sue walks one way will be = 1 - P(A∩B)

= 1 - 0.28

= 0.72

Hence, the probability that Sue will walk at one way is 0.72

Final answer:

To find the probability that Sue walks at least one way, we calculate the complement of the probability of her taking the bus both ways. The probability of Sue taking the bus to and from the shops is 0.4 times 0.7, which equals 0.28. The probability that she walks at least one way is then 1 minus 0.28, giving us 0.72.

Explanation:

The question involves calculating the probability that Sue walks at least one way to or from the shops, given the probabilities of her taking the bus. We are given that the probability of Sue catching the bus to the shops is 0.4 and from the shops is 0.7. To find the probability of walking at least one way, we consider the complement of the event that she takes the bus both ways.

Firstly, we calculate the probability that she takes the bus both ways:

P(Bus to and from shops) = P(Bus to shops) × P(Bus from shops) = 0.4 × 0.7 = 0.28

Now, the probability that she doesn't take the bus both ways (which means she walks at least one way) is the complement of the above event:

P(Walk at least one way) = 1 - P(Bus both ways) = 1 - 0.28 = 0.72

Therefore, the probability that Sue walks at least one way is indeed 0.72, as required to show.

No, there are no inscribed angle in this diagram; Option D

Step-by-step explanation:

~ Let us apply process of elimination to solve this problem ~

Option 1. This first example states firstly that m∠SRT is an inscribed angle. That is not true, by definition an inscribed angle is an angle created by two chords that share a common endpoint. Neither RS nor RT are chords, in fact they each are radii, creating a central angle instead.

Option 2. m∠RST is not created by two chords, instead by arc ST and radii RS ⇒ and I believe I am not familiar with what angle it is reffered to, if at all it is named.

Option 3. As stated before, ∠SRT is not an inscribed angle; by definition an inscribed angle is an angle created by two chords that share a common endpoint, and neither RS nor RT are chords.

Option 4. Through elimination, Option D is the only possible answer left: Answer: No, there are no inscribed angle in this diagram

Answer:

4 cups of milk

Step-by-step explanation:

Answer:

In order to make enough rice pudding for 8 servings, you would need four cups of milk.

Step-by-step explanation:

First, identify what you know:

1) It takes 2 1/2 (2.5) cups of milk to make enough rice pudding for five people.

Simply, calculate how much is needed for one serving.

2.5/5 = 0.5

Now, we know that one serving of rice pudding requires 1/2 of a cup of milk. So, simply multiple by 8, to find how much is needed for 8 servings.

0.5 x 8 = 4 cups

Four cups of milk would be needed to make rice pudding for 8 servings.  

Answer: The first answer is A. vertical  stretch

Step-by-step explanation: The next one is B. vertical compression

The graph of the function y = 2^x represents a vertical stretch.

The given function is y = 2^x. To determine if it represents a vertical stretch or vertical compression, we need to examine the value of the coefficient in front of the exponent which is 2. If the coefficient is greater than 1, it represents a vertical stretch. If the coefficient is between 0 and 1, it represents a vertical compression. In this case, the coefficient is 2 which is greater than 1, therefore the graph of the function y = 2^x represents a vertical stretch.

Answer:

Both cos(17°) and sin(x°) can be represented by the ratio a/c. The angles measuring 17° and x° are complementary angles. This means x° + 17° = 90°

Therefore, x = 90-17 Since cos(17°)=sin(x°), this also shows that cos(17°)=sin( 90-17)°

this is the correct answer.

The required possibilities for the blanks as b/c, 90 degrees, (90° - 17°), and (90° - 17°). Where 17° and x° are complementary angles

The complementary angles are defined as when pairing of angles addition to 90° then they are called complementary angles.

In the given question,

Both sin(17°) and cos(x°) can be represented by ratio b/c because values of sin(17) and cos(x) are b/c.

Since 17° and x° are complementary angles, hence the value of x will be = 73 degrees. And sin(17°) = cos(x°), therefore sin(17°) = cos(90° - 17°).

Therefore, the required possibilities for the blanks as b/c, 90 degrees, (90° - 17°), and (90° - 17°).
