Answer:

a) 08:30   b) 07:54  c) 26 minutes

Step-by-step explanation:

a) Bus leaves Church Street at 07:59. Bus Station times are at 07:40, 08:30 and 9:20. 07:40 is 9 minutes is earlier then 07:59 (07:59 > 07:40) therefore its 08:30.

Answer: 08:30.

b) If Jo has to get there at 8.30am, the time of the latest bus she can take is the one at 08:44. 07:04 is too early and so is 07:54.

Answer: 07;54

c) Lets use the bus that comes to School Road at 08:04 to make it easier. The bus will arrive at 08:30 at Bus Station. Focus on the minutes, not hours. 30 - 4 = 26, meaning it will take 26 minutes from School Road to the Bus Station.

Answer: 26 minutes

Step-by-step explanation:

The solution is, its height is 3.5 inches. i.e. is  822.5 ft.

In mathematics, multiplication is a method of finding the product of two or more numbers. It is one of the basic arithmetic operations, that we use in everyday life.

here, we have,

If 1 inch is 235 feet

and it’s height is 3.5 inches

we would multiply the 235 by 3.5

i.e. 235*3.5

 =822.5 ft.

and get our answer: 822.5ft

Hence, The solution is, its height is 3.5 inches. i.e. is  822.5 ft.

Answer: To find the product of two rational expressions, we multiply the numerators together to get the new numerator and multiply the denominators together to get the new denominator.

So, (2/x) * (3/2x-5) = (2 * 3) / (x * (2x-5)) = 6 / (2x^2 - 5x)

There are 32 waiters in the restaurant.

The ratio is a numerical relationship between two values that demonstrates how frequently one value contains or is contained within another.

Given:

The ratio of diners to waiters is 1:8 respectively.

Let x be the number of diners and 8x be the number of waiters.

If the total number of people in the restaurant is 36,

that means, 8x + x = 36

x = 4

Then, the number of waiter = 32.

If the student walks 3 miles north, south, east, or west,  the location at the end of the walk are respectively, (-10,-9). (-4,-9), (-7,-6). (-7, -12).

So Option A is correct

In mathematics, subtraction is an operation which means taking away a few portions of the group or few things from a whole part.

For example, if we take 4 pencils out of 10 then remaining pencils are 6

so this process is called subtraction.

And opposite operation of subtraction is known as addition, which means in addition, few portion provided to the whole part.

Given that,

A student starts a walk at (-7, -9)

If the student walks 3 miles north, south, east, or west,

The location at the end of the walk = ?

The area of the napkin will be 162.5 inches².

The area of a square is -

{A} = Side x Side

Given is that a square piece of cloth with an area of 324 inches² is folded in half twice to form the napkin.

The area of the cloth is -

{A} = 324

Let the side of the square cloth be {a}. So, we can write -

a² = 324

a = √324

{a} = 18                                              ... Eq { 1 }

The diagonal of the square will be the base length of the napkin (in the form of triangle). So, we can write -

d² = a² + a²

d² = 2a²

d² = 648

d = √648

{d} = 25.5 inches                                       ... Eq { 2 }

The height would be -

h = d/2

h = 25.5/2

{h} = 12.75

The area of the napkin would be -

1/2 x d x h

1/2 x 25.5 x 12.75

162.5 inches²

Therefore, the area of the napkin will be 162.5 inches².

The mass of the sample after four days is 1.75 kg.

The decay rate for a radioactive substance follows the exponential decay formula:

m(t) = m₀ * e^(-kt),

where m₀ is the initial mass, m(t) is the mass at time t, k is the decay rate parameter, and e is the base of the natural logarithm.

Given that the initial mass of the sample is 2.05 kg and the decay rate parameter is 4% per day, the formula becomes:

m(t) = 2.05 * e^(-0.04t).

To find the mass after four days, we substitute t = 4:

m(4) = 2.05 * e^(-0.04 * 4)

Answer:

36/27

Step-by-step explanation:

SOHCAHTOA, so tan is opposite over adjacent.

opposite = 36

adjacent = 27

So, tan C is 36/27

The value of ∠C is 73 degrees.

A triangle is a three-sided polygon that consists of three edges and three vertices.

We need to find the value of ∠C

the value of ∠A is 59 degrees and  the value of ∠B is 48 degrees.

We know that from angle sum property the sum of three angles is 180 degrees.

∠A+∠B+∠C=180

59+48+∠C=180

107+∠C=180

Subtract 107 from both sides

∠C=180-107

∠C=73 degrees.

Hence, the value of ∠C is 73 degrees.

Note that the best description for the graph is a > 4 is "A vertical solid line at (4,0) with the shading to the right of the line." (Option B)

Note that the inequality means that a is greater than 4. This means that the end value 4 is not included.

To graph the inequality " > " a dashed line is used. The inequality does not contain any y - value in it.

Hence, it has only one vertical line at a> 4 and is shaded for all values of a greater than 4.

Thus, the graph that fits the inequality is a vertical dashed line, shaded to the right of the line.

The delivered price (including freight) of the living room set is $2858.

To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.

Given:

List Price = $5800

Trade  discount = 50%

So, Price after discount

= $5800 - 50% x $5800

= 5800- 2900

= $2900

if Levin pays within 10 days he will have a discount of 3%, So,

3% x $2900

= $87

Thus, the Delivered price = $2900 -$87+ freight charges ( shipping)

The first step in obtaining the number of solutions of the system of equations is obtaining the linear function that represents each line.

The slope-intercept definition of a linear function is given as follows:

y = mx + b.

In which:

m is the slope.

b is the y-intercept.

here, we have,

The first line goes through these following points:

(0,3) and (3,4).

The slope is given by change in y divided by change in x, hence:

slope = 3

When x = 0, y = 3,

hence the intercept is of b = 3

and the function is given as follows:

y = 3x - 3

The second line goes through these following points:

(0,-2) and (3,-1).

Hence the slope is of:

m = 3

The intercept is of b = -2,

and the equation is given as follows:

y = 3x-2.

Hence the solution is obtained as follows:

The probability that at least one of the codes will have repeating digits is 0.4712.

The term probability refers to the likelihood of an event occurring. Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.

Here, The probability of a pin being repeated is 14.7%

⇒ 14.7/100

After Eliminating the decimal point;

⇒ 14.7/100 = 147/1000

Hence,

The probability that a pin, if selected will have a repeating digit format = 147/1000

The probability of a pin not having repeating digits format is,

⇒ 1 - 147/1000

⇒ 853/1000

If four codes are selected at random (without replacement), the probability that all four of the codes will not have repeating digits format is,

⇒ (853/1000) x (852/999) x (851/998) x (850/997)

The coordinates of point T' after Ry-axis is (2, 5) and the coordinates of point T' after Rx-axis is (-2, -5). The solution has been obtained by using the concept of reflection.

What is reflection?

In geometry, a reflection is referred to as a flip. In a reflection, the shape is reflected. An image will reflect over a line known as the line of reflection.

We are given a point T(-2, 5)

In order to find the coordinates of the reflection of  point in the y-axis, we need to change the sign of abscissa i.e., x-coordinate and retain the ordinate i.e., y-coordinate.

So, we get the image of (-2 , 5) as (2, 5)

Thus, the coordinates of point T' after Ry-axis is (2, 5).

When we reflect across the x-axis, the x-coordinate remains the same, but the y-coordinate is taken to be the additive inverse.

So, we get the image of (-2 , 5) as (-2, -5).

Thus, the coordinates of point T' after Rx-axis is (-2, -5).

Hence, the coordinates of point T' after Ry-axis is (2, 5) and the coordinates of point T' after Rx-axis is (-2, -5).
