Answer:4f+3t=7.95  2f+10t=9.50

Step-by-step explanation:

Let the cost of fudge be f and taffy be t.

Chris bought 4 pieces of fudge and 3 pieces of taffy for a total of $7.95

 4 f + 3 t = 7.95

Samantha bought 2 pieces of fudge and 10 pieces of taffy for a total of $9.50

 2 f + 10 t = 9.5

The A ∩ B ∩ C = {0}, if  A = {1,3,5,7,9,11}, B = {2,4,6,8,12} and C = {5,10,15,20}.

Any group of objects (elements) in mathematics and logic, whether they are mathematical (such as numbers and functions), is referred to as a set.

Given:

Set A = {1,3,5,7,9,11},

B = {2,4,6,8,12},

C = {5,10,15,20}

Calculate the A ∩ B ∩ C by the formula given below,

A ∩ B ∩ C = {0}

As there is nothing common between sets A, B, and C.

Therefore, A ∩ B ∩ C = {0}.

By evaluating the function in x = -2, we will get:

f(-2) = -2

To do that, we need to evaluate the given linear equation:

f(x) = -x - 4

We want to find f(-2), so we need to evaluate the linear equation in x = -2, this means that we just need to replace the variable by the corresponding number.

Then we will get:

f(-2) = -(-2) - 4

We know that Martin earn $81 last week by raking 27 bags using simple mathematical operations.

A mathematical expression known as an "operation" in mathematics is one that transforms zero or even more input data into a precisely specified actual output.

The number of arithmetic determines the difficulty of the operation.

The four basic operations in arithmetic are addition, subtraction, multiplication, and division, according to the majority of people.

So, money was earned by raking 27 bags.

Martin earns $15 for raking 5 bags.

The amount earned by raking 1 bag:

15/5 = $3

Now, the amount earned by raking 27 bags:

27 * 3 = $81

Therefore, we know that Martin earn $81 last week by raking 27 bags using simple mathematical operations.

Hello,

The slope-intercept form of a linear equation is:

y = mx + b

where m is the slope of the line and b is the y-intercept, which is the point where the line crosses the y-axis.

To write the equation of the line with slope m = -1 that passes through the point (4, 5), you can use the point-slope form of a linear equation, which is:

y - y1 = m(x - x1)

where (x1, y1) is a point on the line and m is the slope of the line. Plugging in the values, we get:

y - 5 = -1(x - 4)

This simplifies to:

y - 5 = -x + 4

Finally, we can rearrange the terms to put the equation in slope-intercept form:

y = -x + 9

This is the equation of the line with slope m = -1 that passes through the point (4, 5).

Whereas students from single parent or two parent homes make up 54% of new students, these students eventually go on to complete their college studies..

By dividing the value by the entire value and multiplying the result by 100, one can compute the percentage. The formula for calculating percentage is (value/total value)100%.When a piece of a whole is stated as a percentage, it is not a fraction but rather a number between 0 and 100. There are three percentages: 100% for everything, 50% for half of it, and 0% for the remaining portion.

calculation

25% of new students come from one-parent households, which equals 0.25;

75% of new students come from two-parent households, which is 0.75.

42% of incoming students from homes with only one parent go on to complete their college studies = 0. 42

58 percent of incoming students who come from two-parent households go on to complete their education =0.58

= 0.25 * 0.42 + 0.75 * 0.58 = 0.54 = 54%.

To obtain the coordinates of the other shape, multiply the original shape by the scale factor

What is the scale factor?

The ratio of the scale of an original thing to a new object that is a representation of it but of a different size is known as a scale factor (bigger or smaller). For instance, we can increase the size of a rectangle with sides of 2 cm and 4 cm by multiplying each side by, let's say, 2.

13.5 / 9 = 1.5

9 * 1.5 = 13.5 \s12 * 1.5 = 18

You have a scale factor of 1.5. (because if u multiply 1.5 by the original shape, u get the new shape)

JKLM ~ WXYZ

Step-by-step explanation:

Given information,

→ 400 m long fencing wire is required to surround square flower garden 2 times.

Now the fence taken for 1 time,

→ 400 ÷ 2

→ 200 m

Formula we use,

→ P = 4 × L

[Perimeter of square]

Then the length of the garden is,

→ P = 4 × L

→ 200 = 4L

→ 4L = 200

→ L = 200/4

→ [ L = 50 m ]

Hence, length of garden is 50 m.

The value of a for system ax + 12y = −6, 2x − 6y = 4 having no solution is a = -4.

Equation: A statement that two variable or integer expressions are equal. In essence, equations are questions, and the motivation for the development of mathematics has been the systematic search for the answers to these questions.

Given:

ax + 12y = −6

2x − 6y = 4

Calculate the value of a by using the condition of no solution of the system given below,

[tex]a_1 / a_2 = b_1 / b_2 \neq c_1/c_2[/tex]

So, a₁ / a₂ = b₁ / b₂

a / 2 = 12 / (-6)

a / 2 =  - 2

a = -4

And -4 / 2 ≠ -6 / 4

Therefore, the value of a for system ax + 12y = −6, 2x − 6y = 4 having no solution is a = -4.

A diagram is provided, on which R S T U's perimeter is 72 and R V's is 16, RT= 32  and UV ≈ 8.2.

A diagram is provided, on which R S T U's perimeter is 72 and R V's is 16.

Finding R T and U V is our goal.

First, let's assume that the figure RSTU is a rhombus since its perimeter and one-half of a diagonal's length are both provided. RT is the result of adding the segments RV and VT.

RT=RV + VT

We are informed that the RV is sixteen. If RV and VT are congruent, then V T equals 16. So:

R T = 16 + 16 = 32

In order to determine the UV length, we must first determine the RU length. Since a rhombus's sides are the same length, we can divide its perimeter by four to determine

RU= Perimeter/ 4

If we simplify and replace Perimeter with 72, we get:

RU = 72 / 4

RU =18

Since UB is a member of the right triangle RUV created by the intersection of the diagonals, we can now use the Pythagorean theorem to determine its length. So:

U V²+ R V² =  RU²

If R V = 16 and R U = 18, we obtain:

U V² + 16 ²= 18²

By way of summary, we have:

U V² + 256 = 324

U V² + 256 − 256 = 324 − 256

√ UV = √ 68

UV = 8.2462

UV ≈ 8.2

Our recommendations are as follows:

RT= 32

UV ≈ 8.2.
