white flowers = w

6y = 4w

Therefore, the numbers of white and yellow flowers in Hector's arrangements are proportional.

Answer:

$684.38

Step-by-step explanation:

A = Pi / (1 − 1/(1 + i)ⁿ)

where A is the annuity (monthly payment),

P is the present value (the loan),

i is the interest rate per compounding,

and n is the number of compoundings.

P = 35400

i = 0.06 / 12 = 0.005

n = 5 × 12 = 60

A = (35400) (0.005) / (1 − 1/(1 + 0.005)⁶⁰)

A = 684.38

The number of photos that Sam takes in the afternoon is 224.

A percentage is a value or ratio that may be stated as a fraction of 100. If we need to calculate a percentage of a number, we should divide it's entirety and then multiply it by 100.

The percentage therefore refers to a component per hundred. Per 100 is what the word percent means. It is represented by %.

In this case, Sam is taking photos for the yearbook and she takes 140 photos in the morning and in the afternoon, she takes 60% more photos.

The photos taken in the afternoon will be:

= Morning photos + Increase in photo

= 140 + (60% × 140)

= 140 + 84

= 224

He took 224 photos.

Answer:

Step-by-step explanation:

The slopes of both those lines are the same so there is no solution. Use slope triangles to find out the slope. They are both 1/4.

A. No solution

y = 1/4x+5

x - 4y = 4

You can simplify the second equation into y = 1/4x - 1

Since these equations both have the same slope, they are parallel. When two lines are parallel, they have no solutions.

Answer:

The equation has infinite solutions

Step-by-step explanation:

Linear equations can have zero, one or infinite solutions.

If Emma tested two values (3 and 5) for the same equation and they were both true solutions, this means that the equation has more than one solution.

If a linear equation has more than one solution, than the equation has infinite solutions.

Answer:

x = -2

y = -6

Step-by-step explanation:

System of equations given in the question are,

y = x - 4 ---------(1)

y = 4x + 2 -------(2)

For equation (1)

y-intercept of the line → (0, -4)

x-intercept of the line → (4, 0)

Joining these points we can get the graph of the line represented by equation (1).

Similarly, for equation (2),

y - intercept of the line → (0, 2)

x- intercept of the line → (-0.5, 0)

Joining these points we will get the graph of the equation (2).

Solution of these equations will be the point of intersection or common points of both the equations.

From the graph attached,

Solution of the system of equations will be → x = -2

                                                                           y = -6

Step-by-step explanation:

The probability of being a senior is the total number of seniors divided by the total number of students.

The probability of a student walking given that they are seniors can be calculated using Bayes' theorem. Bayes' theorem is a formula that relates conditional probabilities to their inverses. The formula is: P(A|B) = P(B|A) P(A) / P(B)where P(A|B) is the probability of event A given that event B has occurred. In this case, A is "walking" and B is "senior." P(B|A) is the probability of being a senior given that the student is walking, P(A) is the probability of walking, and P(B) is the probability of being a senior. We can also represent the above formula in the form of a tree diagram, where P(walk | senior) is one branch of the tree.

The probability of being a senior is represented by the root of the tree, while the probability of walking is represented by a branch from the root. The probability of walking given that the student is a senior is calculated by dividing the probability of a senior walking by the probability of being a senior. The probability of walking can be calculated by adding up the probabilities of walking for each grade level and dividing by the total number of students.

The mean and variance of the cumulative intensity of all the earthquakes up to time t are both equal to tλ.

The cumulative intensity of all the earthquakes up to time t is the sum of the intensities of all the earthquakes that have occurred up to time t. The intensity of each earthquake is a random variable with distribution . The mean and variance of the intensity of each earthquake are both equal to λ. The mean of the sum of a set of random variables is equal to the sum of the means of the random variables. The variance of the sum of a set of random variables is equal to the sum of the variances of the random variables plus the sum of the covariances between the random variables. In this case, the sum of the random variables is the cumulative intensity of all the earthquakes up to time t. The mean of each random variable is λ, and the covariance between any two random variables is zero. Therefore, the mean of the cumulative intensity of all the earthquakes up to time t is tλ, and the variance of the cumulative intensity of all the earthquakes up to time t is also tλ.

8 ounce of brown rice and 9 ounce quinoa sold.

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given:

Brown rice: $2.00 per pound

Quinoa: $4.50 per pound

let the brown rice sold x ounces

and, let the Quinoa sold be y ounces

So, the equations are:

x + y= 17

2x+ 4.5y= 54

2( 17- y) + 4.5y= 54

34 - 2y + 4.5y= 54

2.5y= 20

y= 20/2.5

y= 8 ounce

and, x= 17-8= 9 ounce

y = 5

For the given equation, we created a situation in which the equation would work and analysed it.

What is meant by equations?

A mathematical equation is a formula that uses the equals sign (=) to represent the equality of two expressions. The expressions on each side of the equals sign are referred to as the "left-hand side" and "right-hand side," respectively, of the equation. Typically, we consider an equation's right side to be zero. As we can balance this by deducting the right-side expression from both sides' expressions, this won't reduce the generality.

a ) Given the equation as:

 g + 3 / 16 = 15

Now we have to create a situation that the equations could represent. We have to create a word problem for the equation.

James had a packet of chocolates. There were a total of 16 students in his class. He bought three more chocolates so that each student received 15 chocolates. How many chocolates did James have in the beginning?

To solve this we take g as the number of chocolates in the beginning.

He bought 3 more chocolates.

So number of chocolates = g + 3

Now he divided it among 16 students equally.

So each student received = g + 3 /16 = 15 chocolates.

b) The situation would not work if the denominator of the equation is doubled. That is 16 * 2 = 32.

Because the number of students is 16.

But if the students were 16*2 = 32 then the situation would work.

Therefore for the given equation, we created a situation in which the equation would work and analysed it.

The number 48,000,000,000 can be written in scientific notation as:

4.8 × 1010 or 48 × 109

Scientific notation is a way of expressing numbers in a concise form. It is typically used when dealing with very large or very small numbers. In scientific notation, a number is written as the product of two factors: a number between 1 and 10, and a power of 10.

For example, to express the number 48,000,000,000 in scientific notation we must first determine the two factors.

First factor: This is the number between 1 and 10. To determine this factor, we must count the number of places to the right of the decimal point (in this case, 0 places) and then move the decimal point that many places to the left.

48,000,000,000 → 4.8

Second factor: This is the power of 10. To determine this factor, we must count the number of places we moved the decimal point and then express this number as a power of 10.

In this example, we moved the decimal point 10 places to the left. Therefore, our power of 10 is 10.

Therefore, the number 48,000,000,000 can be written in scientific notation as:

Answer:

\( \frac{11}{b - 1} = \frac{6}{b + 1} \\ 11(b + 1) = (b - 1).6 \\ 11b + 11 = 6b - 6 \\ 11b + 11 - 11 = 6b - 6 - 11 \\ 11b - 6b = 6b - 17 - 6b \\ 5b = - 17 \\ \frac{5b}{5} = \frac{ - 17}{5} \\ b = \frac{ - 17}{5} \\ b = - 3.4\)

\(\boxed{\underline{\bf \: Answer}}\)

\( \sf \frac{11}{b + 1} = \frac{6}{b + 1} \\ \)

Multiply both sides of the equation by \(\left(b-1\right)\left(b+1\right)\), the least common multiple of b-1,b+1.

\(\sf\left(b+1\right)\times 11=\left(b-1\right)\times 6 \)

Use the distributive property to multiply b+1 by 11.

\(\sf11b+11=\left(b-1\right)\times 6 \)

Subtract 6b from both sides.

\(\sf11b+11-6b=-6 \)

Combine 11b and -6b to get 5b.

\(\sf5b+11=-6 \)

Subtract 11 from both sides.

\(\sf5b=-6-11 \)

Subtract 11 from -6 to get -17.

\(\sf5b=-17 \)

Divide both sides by 5.

\(\sf \: b=\bf\frac{-17}{5} \)

Answer:

12.2

Step-by-step explanation:

Let C be the last angle c + 55° + 35° = 180° (sum of angles in a triangle)

C + 90° = 180°

C = 180° - 90°

C = 90°

Let c be the last side

Using the sine rule a/sinA = b/sinB = c/sinC

Using any of the other two sides,

10/sin55° = c/sin90°

c = 10/sin55° × sin90°

c = 10/0.8192 × 1

c = 12.21

c ≅ 12.2

Answer:

680

Step-by-step explanation:

An easy way to do this is to think of the number as in parts.

213 would be 200 + 10 + 3.

Whereas 467 would be 400 + 60 +7.

Now looking at these numbers, you can add the ones, tens and hundredths place together.

3 + 7 = 10

60 + 10 = 70

200 + 400 = 600

Now you have this equation:

600 + 70 + 10 = 680

The answer to 213 plus 467 would be 680.

Rounding this to the nearest hundredth, the area of the sector is approximately 28.88 f\(t^2\).

To find the area of a sector, we can use the formula:

Area = (θ/360) × π × \(r^2\)

where θ is the central angle in degrees, π is approximately 3.14, and r is the radius.

Given a central angle of 131° and a radius of 7.2 ft, we can plug in these values into the formula to find the area:

Area = (131/360) × 3.14 × (7.2\()^2\)

Calculating this expression:

Area = (0.3639) × 3.14 × (7.2\()^2\)

Area ≈ 28.879 f\(t^2\)

Rounding this to the nearest hundredth, the area of the sector is approximately 28.88 f\(t^2\).
