The area of the rectangular figure with two semicircles on the opposite side is  36.56 sq cm.

The circumference of a circle is the distance around the circle which is 2πr.

The diameter of a circle is the largest chord that passes through the center of a circle it is 2r.

Given, A rectangle with two semicircles on two opposite sides.

The length of the rectangle is 6cm and the width of the rectangle is 4cm.

The two given semicircles have a diameter of 4cm seems obvious.

∴ The area of the total figure is an area of the rectangle added to the area of 2 semicircles which makes up to a circle with a radius 2 cm.

∴ (4×6) + π(2)² sq cm.

= 24 + 4π sq cm.

= 24 + 12.56 sq cm.

= 36.56 sq cm.

If initial sample of 458 grams of a radioactive substance decays according to the function \(A(t)=458e^{-0.038t}\) then the half-life of the substance is 0.

Half-life is the time required for a quantity (of substance) to reduce to half of its initial value.

Given,

An initial sample of 458 grams of a radioactive substance decays according to the function

\(A(t)=458e^{-0.038t}\)

We need to find the half life

\(458=458e^{-0.038t}\)

Divide both sides by 458

\(1=e^{-0.038t}\)

Take log on both sides

\(log1=-0.038t\)

0=-0.038t

t=0

Hence, the half-life of the substance is 0.

The scale factor and the value of x for each figure is given as follows:

A) Scale factor of 1/3, x = 7 m.

B) Scale factor 0.4747, x = 4.5 in.

For Figure A, we have that the ratio between the areas is given as follows:

510/4590 = 1/9.

As the area is measured in square units, while the side lengths are measured in units, the scale factor is the square root of 1/9, hence it is given as follows:

1/3.

Then the value of x is obtained as follows:

x = 21 x 1/3

x = 7 m.

For Figure B, we have that the ratio between the areas is given as follows:

16/71 = 0.22535.

The scale factor is then the square root of 0.22535, which is given as follows:

0.4747.

Then the value of x is given as follows:

x = 9.5 x 0.4747

x = 4.5 in.

Step-by-step explanation:

A 6 sided polygon is 720° degrees

so

720=(8x-1)+110+(5x+36)+116+(7x+19)+(6x-2)

Simplify

720=(8x+5x+7x+6x)+(−1+110+36+116+19+−2)

Combine like terms:

720=26x+278

Step-by-step explanation:

To find the missing term in the geometric sequence 6, [?], 3/2, we can use the formula for the nth term of a geometric sequence:

an = a1 * r^(n-1)

where a1 is the first term, r is the common ratio, and n is the term number.

We know that the first term is 6, and the third term is 3/2. So, we can write:

a1 = 6

an = 3/2

Using the formula above, we can solve for the common ratio:

an = a1 * r^(n-1)

3/2 = 6 * r^(3-1)

3/2 = 6r^2

r^2 = 1/4

r = 1/2 or r = -1/2

Since the common ratio is positive (the sequence is increasing), we can take r = 1/2. Now we can use the formula to find the missing term:

an = a1 * r^(n-1)

an = 6 * (1/2)^(n-1)

To find the missing term, we need to find the value of n. We know that the missing term is between 6 and 3/2, so it must be less than 6. We can try plugging in different values of n until we find the one that gives a term between 6 and 3/2:

n = 2: a2 = 6 * (1/2)^(2-1) = 3

n = 3: a3 = 6 * (1/2)^(3-1) = 1.5

Therefore, the missing term in the sequence is 3.

Step-by-step explanation:

Let x and (x + 1) be the page numbers Josiah can see

Hint 1: x(x + 1) = 930

⇒ x² + x = 930

⇒ x² + x - 930 = 0

Using quadratic formula,

\(x = \frac{-b\pm\sqrt{b^2 -4ac} }{2a}\)

a = 1, b = 1 and c = -930

\(x = \frac{-1\pm\sqrt{1^2 -4(1)(-930)} }{2(1)}\\\\= \frac{-1\pm\sqrt{1 +3720} }{2}\\\\= \frac{-1\pm\sqrt{3721} }{2}\\\\= \frac{-1\pm61 }{2}\\\)

\(x = \frac{-1-61 }{2}\;\;\;\;or\;\;\;\;x= \frac{-1+61 }{2}\\\\\implies x = \frac{-62 }{2}\;\;\;\;or\;\;\;\;x= \frac{60 }{2}\\\\\implies x = -31\;\;\;\;or\;\;\;\;x= 30\)

Answer:

  a) 10:30 a.m.

  b) 75 km/h

Step-by-step explanation:

You want to know the leaving time and speed of a car from Woodlands to Muar if it left half an hour later and arrived half an hour earlier than a coach that traveled the 150 km distance at a speed of 50 km/h and arrived at 1 p.m..

The travel time of the coach is found from the relation ...

  time = distance/speed

  time = (150 km)/(50 km/h) = (150/50) h = 3 h

Then the coach left Woodlands at ...

  1 pm -3 h = 10 am

The car left half an hour later than the coach, so left at 10:30 a.m..

The car arrived at Muar at 12:30 p.m. so had a travel time of ...

  12:30 -10:30 = 2 h

The speed over the 150 km distance is given by ...

  speed = distance/time

  speed = (150 km)/(2 h) = (150/2) km/h = 75 km/h

The average speed of the car was 75 km/h.

Additional comment

The car passed the coach at 11:30 a.m., when both had covered half the distance.

Answer:

Step-by-step explanation:

Circumference of a circle = \( \pi d \)

Diameter = d

Therefore, ratio of circumference of a circle to its diameter would be:

\( \pi d : d \)

\( = \frac{\pi d}{d} = \pi \) => (d cancels d)

Therefore, the ratio of the circumference of a circle to its diameter is \( \pi \)

The required height of the parallelogram is 2/3. Option B is correct.

Given that,
The area of a parallelogram is 24 square units. One side of the parallelogramis 36 units long. The other side is 4 units long. Which could be the parallelogram's height is to be determined.

A parallelogram is a quadrilateral consisting of pairs of parallel side.

Here,
We have given the area of the parallelogram and the measure of its base. So,
Area of the parallelogram = base * height
                                       24 = 36 * height
                                       height = 2 / 3

Thus, the required height of the parallelogram is 2/3. Option B is correct.

Answer:

1 out of 6

Step-by-step explanation:

Each roll of the die is an independent event. This means that the second roll does not rely on the first roll. The probability of rolling a six is one out of six. The probability of rolling a two is also one out of six. Since the two events are independent of each other, you would take the average of the two probabilities, which since they are both one out of six, the probability of rolling a six and then a two is one out of six.

The wheelchair access ramp must be 216.09 inches long.

To find the length of the wheelchair access ramp, we can use trigonometry.

The tangent function relates the angle of elevation to the ratio of the opposite side (height) to the adjacent side (length of the ramp).

Let's denote the length of the ramp as "x".

The height of the ramp is given as 18 inches.

Using the tangent function:

tan(angle of elevation) = height/length of the ramp

tan(4.8 degrees) = 18/x

To solve for x, we can rearrange the equation:

x = 18 / tan(4.8 degrees)

Using a calculator to evaluate the tangent of 4.8 degrees:

x = 18 / 0.08331

x= 216.09
