The fraction of crayons that are blue triangle is 1/5.

The ratio of blue rounds to non-blue crayons is

The fraction of footballs that are brown rubber footballs is 8/15 and here are 4 times as many rubber footballs as non-rubber footballs

A fraction represents a part of a whole.

1. Let's say Alexa had a total of 5x crayons in the bag.

the number of blue crayons in the bag is 2x,

There is one triangle for every two round crayons,

(1/2) × 2x = x (By condition)

So, the fraction of crayons that are blue triangle is x / 5x = 1/5.

The number of blue round crayons is 2x.

The number of non-blue crayons is 5x - 2x = 3x,

The ratio of blue rounds to non-blue crayons is 2x / 3x = 2/3.

2.

4 out of 5 wall footballs are rubber, 4/5 of the footballs in the bag are rubber.

The fraction of rubber footballs that are brown is 2/3.

The fraction of footballs that are brown rubber footballs is (4/5) × (2/3) = 8/15.

The fraction of non-brown rubber footballs is (4/5) - (8/15) = 4/15.

The ratio of rubber footballs to non-rubber footballs is (4/5) / (1/5) = 4.

So there are 4 times as many rubber footballs as non-rubber footballs

Hence,  the fraction of crayons that are blue triangle is 1/5.

The coordinate from point of intersection is (3, 11)

To find the intersection point of the diagonals of ABCD, we need to find the point where the lines containing the diagonals intersect.

The diagonal connecting A and C has slope:

m₁ = (y₂ - y₁) / (x₂ - x₁)

= (-2 - 6) / (3 - 3)

= undefined

This is because the line is vertical, and so has no slope. However, we can still write an equation for this line using the x-coordinate of point C:

x = 3

The diagonal connecting B and D has slope:

m₂ = (y₂ - y₁) / (x₂ - x₁)

= (-4 - 8) / (1 - 5)

= -3/2

We can write an equation for this line using point-slope form and the coordinates of point B:

y - y₁ = m₂(x - x₁)

y - 8 = (-3/2)(x - 5)

y - 8 = (-3/2)x + 15/2

y = (-3/2)x + 31/2

Now we can find the point of intersection by solving the system of equations given by the two lines:

x = 3

y = (-3/2)x + 31/2

Substituting x = 3 into the second equation, we get:

y = (-3/2)(3) + 31/2

y = 22/2

y = 11

The angles in degree for the given triangle is 74 degrees, 78 degrees and 28 degrees.

In geometry, an angle is the figure formed by two rays, called the sides of the angle, that share a common endpoint, called the vertex of the angle. Angles are usually measured in degrees or radians and are used to describe the amount of rotation between two intersecting lines or to measure the size of a shape. Angles can be acute (less than 90 degrees), right (exactly 90 degrees), obtuse (greater than 90 degrees but less than 180 degrees), straight (exactly 180 degrees), or reflex (greater than 180 degrees but less than 360 degrees). Angles play an important role in various fields of study such as mathematics, physics, engineering, and architecture.

Here,

To find m23, we need to use the fact that the sum of the angles in a triangle is 180 degrees.

We know that m21 + m23 + m32 = 180 degrees. Rearranging this equation, we get m23 = 180 degrees - m21 - m32.

From the given information, we have:

m21 = (5x + 4) degrees

m32 = 180 degrees - mz2 - mz3 = 180 degrees - (6x - 6) - (10x + 12) = 174 - 4x degrees

Substituting these values into the equation for m23, we get:

m23 = 180 degrees - m21 - m32

= 180 degrees - (5x + 4) - (174 - 4x)

= 6x + 2 degrees

Therefore, m23 is 6x + 2 degrees.

5x+4+6x-6+168-10x=180

x+166=180

x=14

5x+4=5*14+4

Proportion of classrooms with at least 2 students sharing a birthday = (8+9+7+11+7+6+8+6+10+8+7+11+8+7+10+10)/16 = 0.7125

The mean number of classrooms with at least 2 students sharing a birthday is 0.7125. We can use this value to calculate the t-statistic.

t-statistic = (0.7125 - 0.4) / (sqrt(0.4 * 0.6 / 16)) = 5.766

Using a one-tailed t-test with 15 degrees of freedom and an alpha level of 0.05, the critical t-value is 1.753. Since the calculated t-statistic is greater than the critical t-value, we can reject the null hypothesis.

The p-value is very small (less than 0.0001), indicating strong evidence against the null hypothesis.

To convert micrograms (μg) to milligrams (mg), you can divide the number of micrograms by 1000. So, the formula for converting micrograms to milligrams is: mg = μg / 1000.

To convert micrograms to milligrams, divide the number of micrograms by 1000. This is because there are 1000 micrograms in 1 milligram. For example, if you have a measurement of 5000 micrograms and you want to convert it to milligrams, you would divide 5000 by 1000 to get 5 milligrams. This conversion is useful in many fields, including medicine, where medication dosages are often measured in milligrams, and scientific research, where precise measurements of small amounts of substances are necessary.

For example, let's say you have a measurement of 5000 micrograms and you want to convert it to milligrams:

mg = 5000 μg / 1000

mg = 5 mg

Therefore, 5000 micrograms is equal to 5 milligrams.

Answer:

Below

Step-by-step explanation:

x = first number  

x+1 = second number

x *  (x+1) = 272

x^2  +x  = 272

x^2 + x - 272 = 0     Use Quadratic Formula to find:

x=   16    x+1 = 17          OR       x =   -17     x+1 = -16

Answer:

a. After 4 years, the amount in the account can be found by using the formula for simple interest:

A = P * (1 + r * t), where P is the initial deposit, r is the annual interest rate as a decimal, and t is the number of years.

Plugging in the values, we get:

A = $2,000 * (1 + 0.05 * 4) = $2,000 * 1.2 = $2,400

So after 4 years, there will be $2,400 in the account.

b. After 16 years, the amount in the account can be found using the same formula:

A = $2,000 * (1 + 0.05 * 16) = $2,000 * 1.8 = $3,600

So after 16 years, there will be $3,600 in the account.

c. To find the number of years it will take for the account to contain $2,500, we can use the formula:

t = (A - P) / (P * r), where A is the desired amount.

Plugging in the values, we get:

t = ($2,500 - $2,000) / ($2,000 * 0.05) = ($500) / ($100) = 5 years

So it will take 5 years for the account to contain $2,500.

d. To find the number of years it will take for the account to contain $3,000, we can use the same formula:

t = ($3,000 - $2,000) / ($2,000 * 0.05) = ($1,000) / ($100) = 10 years

So it will take 10 years for the account to contain $3,000.

In the given situation, the required value of x for the given pair of adjacent angles is 30°.

When two angles have a similar vertex and side, they are referred to as neighboring angles.

The vertex of an angle is the point at which the rays that make up its sides come to an end.

When adjacent angles have the same vertex and side, they can be a complimentary angle or supplemental angle.

The definition of adjacent is next to or nearby.

Two next-door residences are an illustration of proximity.

Typically, we think of those who live on our street as neighbors.

So, we have:

x + x + 30 = 90

Now, solve for x as follows:

The distance from the top left corner of the foundation to the bottom right corner is 27 meters.

The distance between two points in space can be calculated using the Pythagorean theorem. In this case, we want to find the distance from the top left corner of the foundation to the bottom right corner.

To do this, we will use the length and width of the foundation, which are 20 meters and 18 meters respectively.

The Pythagorean theorem states that in a right triangle, the square of the distance (c) between the two points is equal to the sum of the squares of the other two sides (a and b). Mathematically, this can be represented as

=> c² = a² + b².

In our case, the two sides are the length (20m) and width (18m) of the foundation. To find the distance, we will first find the square of c by adding the squares of a and b. So,

=> c² = 20² + 18² = 400 + 324 = 724.

To find the distance, we will take the square root of c².

Answer:

Step-by-step explanation:

The simple interest formula is given by I = Prt, where P is the principal amount, r is the interest rate (per compounding period), and t is the time in years.

In this case, the interest rate is 5% per month, so we need to convert it to the equivalent annual interest rate, given by r = (0.05 x 12) = 0.6 (since there are 12 months in a year).

The time is 1.5 years, so t = 1.5.

So, the simple interest is:

I = Prt = 1000 x 0.6 x 1.5 = 900

The future value of the investment is the principal amount plus the interest earned, given by:

Future value = P + I = 1000 + 900 = 1900

So, the future value of the investment is $1900.

Answer: the future value of the simple interest investment, where 5% interest is paid monthly for 1.5 years on $1000, is $18074.06.

Step-by-step explanation:

To determine the future value of a simple interest investment, we need to calculate the interest earned over the investment period and add it to the original investment amount. Here's a step-by-step explanation for calculating the future value of a simple interest investment with a 5% interest rate paid monthly for 1.5 years on $1000:

Step 1: Convert the annual interest rate to a monthly rate.

Since the interest rate is 5% per year and the interest payments are made monthly, we need to convert the annual interest rate to a monthly interest rate. We can do this by dividing the annual interest rate by 12:

Monthly interest rate = Annual interest rate / 12

Monthly interest rate = 5% / 12 = 0.05 / 12 = 0.00417

Step 2: Calculate the interest payment for each month.

For each month, we can calculate the interest payment by multiplying the monthly interest rate by the current balance:

Interest payment = Monthly interest rate * Current balance

Let's calculate the interest payment for the first month:

Interest payment = 0.00417 * $1000 = $4.17

Step 3: Add the interest payment to the current balance to get the new balance.

After each interest payment, we can add it to the current balance to get the new balance:

New balance = Current balance + Interest payment

New balance = $1000 + $4.17 = $1004.17

Step 4: Repeat the steps for each month.

We can repeat steps 2 and 3 for each of the 12 months in the first year and then for the 6 months in the second year.

Step 5: Add up the final balance.

After all 18 interest payments have been made, the final balance will be the sum of all the new balances:

Final balance = $1004.17 + $1004.17 + ... + $1004.17 (18 times) = $1004.17 * 18 = $18074.06

So, the future value of the simple interest investment, where 5% interest is paid monthly for 1.5 years on $1000, is $18074.06.

So convert both 1/2 and 1/4

1/4 x 1/1 = 1/4

1/2 x 2/2 = 2/4

Now we can just subtract the numerator from each other.

2/4 - 1/4 = 1/4

We cannot simplify the difference any more so keep it the same.
