In quadrilateral ABCD, m∠C = 70°.

A quadrilateral in geometry is a four-sided polygon with four edges and four corners.

Given:

ABCD is a quadrilateral.

m∠A =80°, m∠B = 100° and m∠D = 110°.

The sum of all the interior angles is 360°.

m∠A + m∠B + m∠C + m∠D = 360°.

80 + 100 + 110 + m∠C = 360

m∠C = 360 - 290

m∠C = 70°

Therefore, m∠C = 70°

Step-by-step explanation:

In a quadrilateral, the sum of the measures of the angles is 360 degrees. Therefore, if we know the measures of three of the angles in a quadrilateral, we can use this information to find the measure of the fourth angle.

In this case, we know that:

m(<A) = 80 degrees

m(<B) = 100 degrees

m(<D) = 110 degrees

So, to find m(<C), we can use the equation:

m(<A) + m(<B) + m(<C) + m(<D) = 360

Substituting in the known values, we get:

80 + 100 + m(<C) + 110 = 360

Solving for m(<C), we get:

m(<C) = 360 - (80 + 100 + 110) = 360 - 290 = 70 degrees

So the measure of angle C is 70 degrees.

The meaning of the y-intercept is that Nora paid her plumber an initial fee of $50.

In Mathematics, the slope-intercept form of a line can be calculated by using this linear equation:

y = mx + c

Where:

In Mathematics, the y-intercept is sometimes referred to as an initial value and the y-intercept of any graph such as a linear function, generally occur at the point where the value of "x" is equal to zero (x = 0).

In this scenario, the y-intercept of this equation is 50 and it represents the initial fee being charged by the plumber.

Answer:

y =  [tex]\frac{1}{3}[/tex]x + 6

Step-by-step explanation:

The equation we currently have right now is y = -3x+2. Since we know that the line equation is y = mx + b, let's take out m to find the slope of a perpendicular line. M will be -3.

To convert a regular slope to a perpendicular one, we have to:

- reciprocal/flip it (this means that if m = 3, the perpendicular will be [tex]\frac{1}{3}[/tex])

- swap the signs (this will mean that if a number is positive, then it will become negative)

Therefore, if m = -3, the perpendicular slope will be [tex]\frac{1}{3}[/tex] (we flipped and changed signs)

Now, we are also given that this line passes through the point (6,8), so we can use this formula: [tex]y - y1 = m(x-x1)[/tex]

What do we know right now?

- y1 = 8 (from (6,8))

- x1 = 6 (from (6,8))

- m =  [tex]\frac{1}{3}[/tex]

Let's plug in what we know:

y - 8 =  [tex]\frac{1}{3}[/tex](x - 6)

y =  [tex]\frac{1}{3}[/tex](x-6) + 8

y =  [tex]\frac{1}{3}[/tex]x - 2 + 8

y =  [tex]\frac{1}{3}[/tex]x + 6

The amount for each berry are 5.60 and 1.60 respectively.

An equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =

Given that, Jeffrey wants to make jam. He needs a combination of raspberries and blackberries totaling six pounds. Blueberries cost $1.00 per pound, and raspberries cost $2.00 per pound. If Jeffrey can afford $11.60,

We will set a system of linear equations, to solve this,

Establishing the equation,

Let the amount of raspberries be x and that of blueberries be y,

x + y = 6

y = 6-x...(i)

2x + y = 11.60

y = 11.60 - 2x...(ii)

Equating eq(i) and eq(ii)

6-x = 11.60 -2x

x = 5.60

Put x = 5.60 in eq(i)

y = 6-5.60

y = 1.60

Hence, the amount for each berry are 5.60 and 1.60 respectively.

Georgia  takes 24 minutes to clean the espresso machine by herself.

The correct answer is an option D.

The equation for the situation is:

[tex]\frac{1}{x} +\frac{1}{x-12} =\frac{1}{8}[/tex]

here, x is the number of minutes it takes Georgia to clean the machine by herself.

We need to find the value of x.

Consider the equation,

[tex]\frac{1}{x} +\frac{1}{x-12} =\frac{1}{8} \\\\\frac{(x -12)+x}{x(x-12)}=\frac{1}{8}\\\\\frac{x -12+x}{x^2-12x}=\frac{1}{8}[/tex]

(2x - 12) × 8 = x² - 12x

16x - 96 =  x² - 12x

x² - 12x -16x + 96 = 0

x² - 28x + 96 = 0

x²-24x-4x+96 = 0

(x - 24)(x - 4) = 0

x = 24 or x = 4

If x = 4, then x - 12 would be negative which is not possible.

Thus, it takes 24 minutes for Georgia.

JKLM is a parallelogram with four sides and four angles, meaning its measure of angle K is equal to the measure of angle M.

A parallelogram is a quadrilateral having four equal-length sides and opposing sides that are parallel. It is a two-dimensional form with two pairs of parallel sides and equal angles on all sides.

JKLM has four sides and four angles if it is a parallelogram. Because it is a parallelogram, the opposite sides of the figure will be parallel, as will the opposite angles. This signifies that the angle K measure is equal to the angle M measure. As a result, if the measure of angle M is known, the measure of angle K may be calculated.

For example, if angle M is 70 degrees, then angle K is also 70 degrees. In general, if the measure of angle M is x, the measure of angle K must be x as well.

You can model 3x2/4 as the mathematical expression that represents the division of the product of 3 and 2 by 4. The result of this expression is 3/2.

In mathematics, division is an arithmetic operation that is the inverse of multiplication. Given two numbers, the quotient is the number of times the second number "fits into" the first number.

The product is the result of multiplying two or more numbers together. Dividing a product is the process of finding out how many times one of the factors in the product can be taken to equal the product.

For example, if the product is 12 and the divisor is 3, then the quotient is 4, because 3 x 4 = 12

Where x is the number of stamps Bob has. To solve for x, you can cross-multiply:

3 * 120 = 5 * x

Simplifying:

360 = 5x

x = 72

So, Bob has 72 stamps. To find out how many more stamps Barry has than Bob, you can subtract the number of stamps Bob has from the number of stamps Barry has:
