each muffin cost 3$

Answer:

If the painter will paint for $25 per hour, then the amount of dollars for h number of hours is $25h , if the cost of paint is $15 per can, 10 cans will be $150. The cost C of painting the house is

C= 25h +150

The amount of hours the painter paints is make h the subject of the formula

h= (C - 150)/25

The equation to find the cost of painting the house in terms of the hours worked by the painter is C = 25h + 150

The equation that can be used to find the cost of painting the house in terms of the amount of hours the painter paints is C = 25h + 150. This equation represents the cost of the labor ($25 per hour) plus the cost of the paint (10 cans at $15 per can, which equals $150). The variable h represents the number of hours the painter works.

Answer:

19 meters

Step-by-step explanation:

When Arman finished, Babken is 10 meters behind. So, Babken has 10 meters left.

Ex: Babken has 10 meters left, Cecilia is 9 meters behind.

So, the answer is 10+9=19.

19 meters.

Cecilia's position is  19 m behind when Arman is at the finish line.

Arman, Babken, and Cecilia 3 decided to compete in a 100m run.

Distance is defined as the difference in position.

Here,

Cecilia covers 90% of Babken's covered distance. Babken Covered 90% of Arman distance. So distance covered by Cecilia is.
= 90/100 * 90/100 x 100
= 81m

Now, distance between Cecilia and Arman when he crossed the finish line,
= 100m-81m

=19m

Thus, Cecilia's position is  19 m behind when Arman is at the finish line.

What is the question that you are asking?

Step-by-step explanation:

The factored form of given expression is:

[tex]40x + 24y - 56 = 8(5x + 3y-7)[/tex]

Solution:

Given that we have to factor the given expression

Given expression is:

40x + 24y - 56

We can factor the expression by taking the greatest common factor out

When we find all the factors of two or more numbers, and some factors are the same , then the largest of those common factors is the Greatest Common Factor.

Find G.C.F of 40, 24 and 56

The factors of 24 are: 1, 2, 3, 4, 6, 8, 12, 24

The factors of 40 are: 1, 2, 4, 5, 8, 10, 20, 40

The factors of 56 are: 1, 2, 4, 7, 8, 14, 28, 56

Then the greatest common factor is 8

Thus factor out 8 from given expression

[tex]40x + 24y - 56 = 8(5x + 3y-7)[/tex]

Thus the given expression is factored

We can extend 352.83 and write as  (3 x 100) + (5 x 10) + (2 x 1) + (8/10) + (3/100)

Step-by-step explanation:

Considering the given value 352.83 we can expand that step by step as,

(3 x 100) which will give us a value of 300.

Now adding the multiplied answer of (5 x 10) will give us 350.

Next we can also add the multiplied answer of (2 x 1 ) which will further give us 352.

Now adding the divided answer of (8/10) we will get 352.08

Finally adding the divided answer of (3/100) we will get the exact value of 352.83 as mentioned above.

The expanded notation for the number [tex]352.83[/tex] is [tex](3\times 100)+(5\times 10)+(2\times 1)+(8\times \dfrac{1}{10})+(3\times \dfrac{1}{100})[/tex]

A number can always be written in the expanded notation by multiplying the face value with the face notation.

Here, [tex]3[/tex] is at the [tex]100th[/tex] place of the number so, it can be written as [tex]3\times 100[/tex].

Similarly, the digits which are located after the decimal point can be expanded by dividing the face value of the number by [tex]10[/tex] raised to the power of face notation.

Here, [tex]8[/tex] is present just after the decimal point and so, its expanded form is [tex]8\times \dfrac{1}{10}[/tex].

Hence, the expanded notation of  [tex]352.83[/tex] is [tex](3\times 100)+(5\times 10)+(2\times 1)+(8\times \dfrac{1}{10})+(3\times \dfrac{1}{100})[/tex].

Step-by-step explanation:

The given shapes area is found to be 132 square feet.

Step-by-step explanation:

Step 1; To determine the area of an indefinite shape we must divide it into the shapes that we know. The shape that is given can be split into a rectangle with a triangle on top of it.

Step 2; To determine the area occupied by a different shape, we must sum the areas of the triangle and the rectangle. The given rectangle measures a length of 11 feet and a width of 9 feet. The area of any given rectangle is the multiplication of its length and width. Area of Rectangle = Length * Width = 11 feet * 9 feet = 99 square feet.

Any given triangles area is half the multiplication of its base value and its height value. In the given diagram, the base of the triangle measures a length of 11 feet (same as the rectangle's length) and the length from base to top is 6 feet (Entire shape's height which is 15 feet - the calculated value of the rectangle's width which is 9).

Area of Triangle = [tex]\frac{1}{2}[/tex]* base * height = [tex]\frac{1}{2}[/tex] * 11 feet * 6 feet = 33 square feet.

Step 3; To find the total area of the shape we must add the areas of the rectangle and the triangle.

Area of given shape = Area of rectangle + Area of Triangle

Area of given shape = 99 square feet + 33 square feet = 132 square feet.

STEPS:

1. Start my distributing the 8 through the parentheses on the left side of the equation. 8 times 2x is 16x and 8 times 9 is 72. So we have 16x + 72 = 56.

2. Next, isolate the x-term by adding 72 to both sides of the equation

and we get 16x = -16.

3. Divide both sides by 16 and x = -1.

Option A: 6 ∙ (30 - 1)

Solution:

Given expression is 6 · 29.

Friendlier term means a number can be expressed using other numbers which are closest to the number.

Option A: 6 ∙ (30 - 1)

30 is closest to 29, so which is the friendlier term to 29.

6 · 29 =  6 ∙ (30 - 1)

Option B: 6 ∙ (16 + 13)

16 and 13 are not closest to 29, which are not the friendlier terms.

Option C: 6 ∙ (19 + 10)

19 and 10 are not closest to 29, which are not the friendlier terms.

Option D: 6 ∙ (21 + 8)

21 and 8 are not closest to 29, which are not the friendlier terms.

Hence Option A: 6 ∙ (30 - 1) is the correct answer.

Step-by-step explanation:

Add 18 and 15 then find the GCF

The maximum number of pots she can make is 15.

The process of subtracting one number from another is known as subtraction.

Given that, Tina has 18 sunflower seeds and 15 daisy seeds.

Since Tina wants to distribute the sunflower seeds and daisy seeds equally in each pot, each pot must contain at least one daisy seed and one sunflower seed.

Therefore, if, she has 1 daisy seed and 1 sunflower seed in each pot, then she can make 15 pots, as there are only 15 daisy seeds.

Now, there are only 3 sunflower seeds left but she cannot use them to make a pot as there are no daisy seeds.

Hence, the maximum number of pots she can make is 15.

Answer: [tex]-i\sqrt{10}[/tex]

Step-by-step explanation:

Assuming that you need to simplify the expression, below is the explanation to do it.

Given the following expression:

[tex]-\frac{1}{3}\sqrt{-90}[/tex]

You need to decompose the radicand (The number inside the square root) into its prime factors:

[tex]90=2*3*3*5=2*3^2*5[/tex]

Knowing that, you can rewrite the expression in this form:

[tex]=-\frac{(1)(\sqrt{-2*3^2*5})}{3}=-\frac{\sqrt{-2*3^2*5}}{3}[/tex]

Since [tex]\sqrt{-1}=i[/tex], you must substitute it into the expression:

[tex]=-\frac{i\sqrt{2*3^2*5}}{3}[/tex]

Now you need to remember the following property:

[tex]\sqrt[n]{a^n}=a^{\frac{n}{n}}=a[/tex]

Then, applying that property, you get:i:

[tex]=-\frac{3i\sqrt{2*5}}{3}=-\frac{3i\sqrt{10}}{3}[/tex]

Finally, you must divide the numerator and the denominator by 3. So, you get:

Explanation:

To express the decimal number 0.15151515151 as a fraction, we can observe the repeating pattern. The 15 sequence repeats indefinitely, so we can represent it as 15/99. Finally, we simplify the fraction by dividing both the numerator and denominator by their greatest common divisor, which in this case is 3. Therefore, the decimal 0.15151515151 can be written as the simplified fraction 5/33.

Recognizing the recurring pattern in the decimal as 0.15(15), we express it as a fraction, obtaining 15/99. Simplifying the fraction by dividing both numerator and denominator by their greatest common divisor, which is 3, yields the final result: 5/33. This process highlights the conversion of repeating decimals to fractions.

Answer:

The two numbers are 25 and 15.

Step-by-step explanation:

Let's find out the two numbers, this way:

x = first number

y = second number

This is the equations system:

x + y = 40

x - y = 10

Solving for x in the first equation:

x + y = 40

x = 40 - y

Solving for y in the second equation:

40 - y - y = 10

40 - 2y = 10

-2y = 10 - 40

-2y = - 30

y = -30/-2 = 15

Solving for x:

x + y = 40

x + 15 = 40

x = 40 - 15

x = 25

The two numbers are 25 and 15.

Hey there! :)

~ They give us some good information in this equation. Let's use it! This can be used to change "45 min" into ".75 hours".

~ Now, let's write an equation; "distance = speed * time."

~ 3(.75) + .5x = 6

~ 2.25 + .5x = 6

~ .5x = 6 - 2.25

~ .5x = 3.75

~ x = 3.75/.5

~ x = 7.5 km/hr

Final answer:

To find Jess's running speed, the total distances she walked and ran are calculated and added to equal the given total distance of 6 km. Solving the equation 6 km = 2.25 km + 0.5x km reveals that Jess ran at 7.5 km/h.

Explanation:

To find the value of x, which represents Jess's running speed, we can use the information provided to set up equations based on the distance formula: distance = speed × time.

Jess walked for 45 minutes at 3 km/h. First, convert 45 minutes to hours by dividing by 60: 45 minutes / 60 minutes/hour = 0.75 hours. The distance walked is:

Distance walked = Speed × Time = 3 km/h × 0.75 hours = 2.25 km.

Next, Jess ran for 30 minutes or 0.5 hours at x km/h. The running distance is:

Distance ran = Speed × Time = x km/h × 0.5 hours = 0.5x km.

According to the question, the total distance from the starting point after both activities is 6 km, so:

Total distance = Distance walked + Distance ran

6 km = 2.25 km + 0.5x km

Now, solve for x:

6 km - 2.25 km = 0.5x

3.75 km = 0.5x

x = 3.75 km / 0.5

x = 7.5 km/h

Therefore, Jess ran at 7.5 km/h.

Answer:

[tex]x=70^o[/tex]

[tex]y=110^o[/tex]

Step-by-step explanation:

we know that

In a parallelogram, opposite angles are congruent and consecutive angles are supplementary

In this problem the quadrilateral ABCD is a parallelogram

so

[tex]x=70^o[/tex] -----> by opposite angles in a parallelogram

[tex]x+y=180^o[/tex] ---> by consecutive angles in a parallelogram

substitute the value of x

[tex]70^o+y=180^o[/tex]

[tex]y=180^o-70^o=110^o[/tex]

Answer:

[tex]y =-\frac{1}{3}-2[/tex]

Step-by-step explanation:

We are given;

We are required to determine the equation a line passing through a point (6, -4) and perpendicular to the given line;

y = 3x -3

But; m₁ × m₂ = -1 (For perpendicular lines)

Therefore;

m₂ = -1 ÷ 3

    = -1/3

Therefore, the slope of the line in question is -1/3 and the line passes through (6, -4).

To get its equation, we get another point (x, y)

Then;

[tex]\frac{y+4}{x-6}=\frac{-1}{3}[/tex]

Thus;

[tex]3(y+4) = -1(x-6)\\3y + 12 = -x+6[/tex]

In the form of slope-intercept, the equation will be;

[tex]3y = -x - 6\\y =-\frac{1}{3}-2[/tex]

Thus, the equation of the line is;

[tex]y =-\frac{1}{3}-2[/tex]

The solution is [tex]x = 2 \text{ and } y = \frac{1}{2}[/tex]

Solution:

Let us assume,

[tex]a = \frac{1}{x}\\\\b = \frac{1}{y}[/tex]

Given system of equations are:

[tex]\frac{2}{x} - \frac{3}{y} = -5[/tex]

[tex]\frac{4}{x} + \frac{6}{y} = 14[/tex]

Rewrite the equation using "a" and "b"

2a - 3b = -5 ------------ eqn 1

4a + 6b = 14 -------------- eqn 2

Let us solve eqn 1 and eqn 2

Multiply eqn 1 by 2

2(2a - 3b = -5)

4a - 6b = -10 ------------- eqn 3

Add eqn 2 and eqn 3

4a + 6b = 14

4a - 6b = -10

( - ) --------------------

8a = 4

[tex]a = \frac{4}{8}\\\\a = \frac{1}{2}[/tex]

Substitute a = 1/2 in eqn 1

[tex]2(\frac{1}{2}) -3b = -5\\\\1 - 3b = -5\\\\3b = 6\\\\b = 2[/tex]

Now let us go back to our assumed values

Substitute a = 1/2 in assumed values

[tex]a = \frac{1}{x}\\\\\frac{1}{2} = \frac{1}{x}\\\\x = 2[/tex]

Substitute b = 2 in assumed value

[tex]b = \frac{1}{y}\\\\2 = \frac{1}{y}\\\\y = \frac{1}{2}[/tex]

Thus the solution is [tex]x = 2 \text{ and } y = \frac{1}{2}[/tex]
