Your school is donating items to the local food pantry. Your homeroom is having a competition to see who will donate the most items. You have already donated 14 items and plan to donate 3 more each week. Your friend has already collected 8 items and plans to collect 5 more items each week. Write and solve a system of equations for the number of weeks (x) when you both donate the same number of items (y).

The resultant vector on the car would be a vector pointing north with a magnitude of 2 miles per hour.

The resultant vector is the net effect of two or more individual vectors on an object. It is the overall force or movement that is produced when all the individual vectors are combined. To find the resultant vector, you would add together all of the individual vectors using vector addition. The resultant vector would be represented by a single vector with a certain magnitude and direction.

If a car is rolling south at 8 miles per hour, and a man pushes the car north at 10 miles per hour, subtract the southward velocity from the northward velocity.

10 mph northward - 8 mph southward= 2 mph northward

Therefore, the resultant vector on the car is 2 mph northward.

The company has the total number of employees as 140.

It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.

We are given that company has two offices - one in Portlee and one in Queentown.

The ratio of the number of employees at Portlee to the number at Queentown is given as;

3:4

Now we know that 20% of the employees at Portlee are part-time.

25% of the employees at Queentown are part-time.

Therefore, 3x of 20% are part- time

4x of 25%

Then we have 32 part-time employees.

0.6x + 1x = 32

1.6x = 32

x = 32/1.6

x = 20

Hence, the total number of employees the company has

3x + 4x = 7x

While rotating, the clock's hands are seen to move at a speed of six degrees per minute.

The number of degrees for a clock minute is solved by

60 minutes  = 360 degrees

1 minute = ?

cross multiplying

60 * ? = 360

? = 360 / 60

? = 6

hence 1 minute is 6 degrees

The formula to use to get the calculation is multiplying the number of minutes by 6

Number of degrees in 45 minutes = 45 * 6

Yes, a triangle can have three equal angles. The term "equilateral triangle" is used to describe this.

A 60-degree equilateral triangle has the same length for all three angles. This is due to the fact that all three angles in a triangle have to add up to 180 degrees, and when three angles are equal, the sum is divided equally between them.

An equiangular triangle is another name for an equilateral triangle. An equilateral triangle takes on the form of an equilateral triangle because all of its sides are equally angled. The term "congruent" refers to the fact that all three sides of the triangle are the same length.

Numerous mathematical disciplines, including geometry and trigonometry, make use of equilateral triangles. They are often used to show how other shapes, like parallelograms and rhombi, work. Additionally, they are utilized in the process of determining the perimeter, angles, and area of a triangle.

There are 4 moles of silver equivalent to 2.408 x 1024 atoms.

This can be determined through the use of Avogadro's number, which is the number of atoms or molecules in one mole of a substance. Avogadro's number is equal to 6.022 x 10^23 atoms/molecules per mole. By dividing the number of atoms by Avogadro's number, we can determine the number of moles. In this case, 2.408 x 1024 atoms / 6.022 x 10^23 atoms/mole = 0.04 moles. Since there are 4 moles in 1 mole of silver, this means that there are 4 moles of silver equivalent to 2.408 x 1024 atoms.

Yes, a dilation will always preserve both the orientation of a figure and the orientation of the vertices.

Resizing an item uses a transformation called dilation. Dilation is used to enlarge or shorten the structures. The result of this transformation is an image with the same shape as the original. However, there is a variation in the shape's size. The initial form should be stretched or contracted during a dilatation.

Given:

When we dilate, we change the size.

Imagine it as a zooming in and out process.

As a result, the size will be different, but the form and orientation will remain the same.

So, a dilation will always preserve both the orientation of a figure and the orientation of the vertices.

It is the force that the air above a surface applies to it while gravity pulls the surface toward Earth.

A barometer is frequently used to measure atmospheric pressure.

So, we know that:

64 M/s is the average sustained wind speed.

The equation for mean sustained wind speed:

v = 6.3√1013 - p

Hurricane's means sustained wind speed is 64 m/s,

With the help of the following equation, we can determine the air pressure.

v = 6.3√1013 - p

64/6.3 = √1013 - p

Making both sides square:

(10.1587)² = 1013 - p

Here we have a triangle, and we know that the measures of the interior angles are:

C = 15x

T = 10x + 20

A = 5x + 40

We know that the sum of the interior angles of a triangle must be 180°, then we can write the linear equation:

15x + 10x + 20 + 5x + 40 = 180

(15 + 10 + 5)*x = 180 - 20 - 40

30x = 120

x = 120/30

It is less likely to randomly meet someone who obtained a SAT score of over 1150.

Z score or standard score is defined as the number of standard deviations by which the observed value is above or below the mean value.

The formula for calculating z score is,

z = (x - μ) / σ

where x is the observed value, μ is the population mean and σ is the population standard deviation.

For IQ scores,

z = (80 - 100) / 16 = -1.25

For SAT scores,

z = (1150 - 1000) / 100 = 150/100 = 1.5

z score is closer to 0 for IQ scores and far to 0 for SAT scores.
