Answer:

To calculate Almaz's typing rate in words per minute, you can divide the number of words she typed by the number of minutes it took her.

First, you'll need to convert the number of hours Almaz spent typing into minutes. You can do this by multiplying the number of hours by the number of minutes per hour. There are 60 minutes in an hour, so if Almaz spent 3.5 hours typing, she spent 3.5 * 60 = <<3.5*60=210>>210 minutes typing.

Then, to calculate Almaz's typing rate, you can divide the number of words she typed by the number of minutes it took her: 9050 words / 210 minutes = <<9050/210=43>>43 words per minute.

So Almaz's typing rate was approximately 43 words per minute.

The value of the tangent JK in the cyclic quadrilateral is 14.25

A cyclic quadrilateral is a four-sided polygon for which the opposite angles are supplementary, meaning that the sum of the angles is equal to 180 degrees. Additionally, a cyclic quadrilateral can also be defined as a quadrilateral that can be inscribed in a circle, meaning that all four vertices of the quadrilateral lie on the circumference of the same circle.

To find the value of x, we can use Pythagoras theorem.

c² = a² + b²

18² = 11² + x²

x² = 18² - 11²

x² = 203

x = √203

x = 14.25

The graph that describes the relationship between the money raised and the number of students is A. graph with the x axis labeled number of students and the y axis labeled amount of money raised and a line going from the point 0 comma negative 100 through the point 2 comma negative 80.

The decorations for the dance cost $ 100 which means that the students would start from a negative amount when raising money. This negative amount is - 100 which is the amount made when there are zero students.

When two students pay for attending, they will pay :

= $ 20

The amount of money raised would then be:

The value of t is the total time she took in her whole journey = 1 hour and 30 minutes.

The definition of time is the system of those sequential relations that any event has to any other, as past, present, or future.

Given that, Layla went for a 10 km run. She ran the first 5 km in 30 minutes, then rested for 25 minutes. She then ran the rest of the way in 35 minutes.

The value of t will be the total time she took in her whole journey,

Therefore,

She ran for 30 minutes, then she 25 minutes, and then she completed the rest of the journey in 35 minutes'

SO, the total time she took = 30+25+35 = 90 minutes

90 minutes = 60 minutes + 30 minutes

Answer:

To find the number of times that Aria's commute is between 32 and 35 minutes, we need to find the probability that her commute time is between 32 and 35 minutes and then multiply that probability by the total number of commutes per year.

To find the probability that Aria's commute time is between 32 and 35 minutes, we need to find the area under the normal curve between those two values.

We can use the following formula to convert the values 32 and 35 to standard units:

z = (x - mean) / standard deviation

Plugging in the values, we get:

z1 = (32 - 28) / 4.5 = 0.89

z2 = (35 - 28) / 4.5 = 1.56

To find the area under the curve between these two values, we can use a standard normal table or a calculator to find the area between these two values. The result is approximately 0.22.

Multiplying this probability by the total number of commutes per year gives us the number of times that Aria's commute is between 32 and 35 minutes.

So the number of times that Aria's commute is between 32 and 35 minutes is approximately 262 * 0.22 = 57.24, which is about 57 times to the nearest whole number.

The graph of the function would be a parabola with zeros at (0,0), (-1,4), (-3,0), (2,0), (0,-2), (3,0), (-1,0), (0,-3).

A function is a mathematical relationship between two or more variables where one variable (the output) is determined by the values of the other variables (the inputs). Functions are often written as an equation, such as y = f(x), where x is the input and y is the output. The equation defines the relationship between x and y and how the output (y) changes as the input (x) changes. Functions can be used to model real-life situations, such as predicting population growth or modeling the motion of objects.

A kite is a quadrilateral which implies the sum of its interior angles is equal to 360°.A kite is symmetrical about its main diagonal and the angles where the adjacent pairs of sides meet are equal.

m∠XYW = 23°

m∠ZWY = 41°

m∠XYZ = 2 × 23° {main diagonal bisect m∠XWZ}

m∠XYZ = 46°

m∠XWZ = 2 × 41° {main diagonal bisect m∠XYZ}

m∠XWZ = 82°

m∠WXY = m∠WZY

2(m∠WXY) = 360° - (82° + 46°) {sum of interior angles of a quadrilateral}

2(m∠WXY) = 360° - 128°

The actual distance between two towns 15cm apart on the map is 6km.

Distance, a scalar quantity, measures the amount of space an object has travelled through while in motion. The distance when represented on a graph are usually scaled to a value that can be easily represented, rather than actual distance.

When using the cross-multiplication approach, the denominator of the first term is multiplied by the numerator of the second term, and vice versa. Cross-multiplication method can be used to solve linear equations containing two variables.

Given that:

2.5cm = 1km

15cm = x km

Amount to be repaid for Bank A is $2,696.625 and Amount to be repaid for Bank B is $2,741.25. However, I will choose Bank B because it offers a lower interest rate.

The formula to calculate the simple interest is;

I = PRT

Where;

P is principal

R is rate

T is time

Now, we are given that;

Bank A;

Principal amount; P = $2550

Interest rate; R = 11.5% = 0.115

Time; t = 6 months = 0.5 years

Thus;

I = (2550 * 0.115 * 0.5)

I = $146.625

Amount to be repaid = 2550 + 146.625

Amount to be repaid = $2,696.625

Bank B;

Principal amount; P = $2550

Interest rate; R = 7.5% = 0.075

Time; t = 12 months = 1 year

Thus;

I = (2550 * 0.075 * 1)

I = $191.25
