Part 2: Find the measure for each angle.

The value of the given expression, -50 + 5/13p, when p = -26 is -60

From the question, we are to evaluate the given expression for the given value of p

The given expression is

-50 + 5/13p

and

The given value of p is p = - 26

Substitute the given value of p into the given expression

That is,

-50 + 5/13p

When p = -26, the expression becomes

-50 + 5/13(-26)

Simplify

-50 + 5(-2)

-50 - 10

= - 60

The equation which models the product is, A = 6 x 8

The fundamental concept of repeatedly adding the same number is represented by the process of multiplication. The results of multiplying two or more numbers are known as the product of those numbers, and the components that are multiplied are referred to as the factors.

Given that,

A area model,

which has 6  box in column arrangement and 8  box in row arrangement,

Suppose, each box has 1 unit square area

Now, area of a model can be written as,

Area = Number of box in column x Number of box in row

Number of box in column  = 6

Number of box in row = 8

Each box has 1 unit square area,

So,

A = 6 x 8

   = 48 unit square

Hence, it can be represented as, A = 6 x 8

The scale factor for the given quadrilateral would be 1.5.

A scale factor is a numerical value that is used to represent an object's enlarged or shrunk shape. It is a number that can be used to alter the size of any geometric figure or shape in relation to its original size. It aids in altering the figure's size but not its shape.

Given that the two quadrilaterals are similar to each other and are dilated by some scale factor.

The scale factor will be calculated as:-

Scale factor = 15 / 10

Scale factor = 1.5

Answer:

x = - 3.5 , y = - 5.5

Step-by-step explanation:

y = x - 2 → (1)

y = 3x + 5 → (2)

substitute y = 3x + 5 into (1)

3x + 5 = x - 2 ( subtract x from both sides )

2x + 5 = - 2 ( subtract 5 from both sides )

2x = - 7 ( divide both sides by 2 )

x = - 3.5

substitute x = - 3.5 into either of the 2 equations for y

substituting into (1)

y = x - 2 = - 3.5 - 2 = - 5.5

then x = - 3.5 and y = - 5.5

The set {10,17,27} does not represent the three sides of a triangle,

Having three edges and three vertices, a triangle is a three-sided polygon. The fact that a triangle's internal angles add up to 180 degrees is its most crucial characteristic. This characteristic is known as the triangle's angle sum property.

Given  the sets for the triangles,

property of triangles says that,

The length of a triangle's two longest sides added together is longer than the third side.

Similarly to this, the length of the third side of a triangle third side is shorter than the difference between its two sides.

1: given sides are 10, 17, 27

according to the property sum of 10 and 17 should be greater than  27 but sum  is equal to 27,

10 + 17 = 27,

so the sides do not represent the triangle

2: sides are 9, 22, 30

here 9 + 22 > 30

the set represents the triangle.

3: sides 6, 16, 19

6 + 16 > 19

the set represents the triangle.

a) C(n) = 0.74 * min(n, 100) + 0.69 * max(n - 100, 0)
b) 39.22
c)  143.69

Step-by-step explanation:

(a) We can write a piecewise function to describe the cost C(n) of n CDs purchased:

C(n) = 0.74 * min(n, 100) + 0.69 * max(n - 100, 0)

(b) The cost of 53 CDs is:

C(53) = 0.74 * min(53, 100) + 0.69 * max(53 - 100, 0) = 0.74 * 53 = 39.22

(c) The cost for 201 CDs is:

C(201) = 0.74 * min(201, 100) + 0.69 * max(201 - 100, 0) = 0.74 * 100 + 0.69 * 101 = 74 + 69.69 = 143.69

The estimate for the population in 2010 is given as follows:

The slope-intercept definition of a linear function is given as follows:

y = mx + b.

In which:

Two points for the function are given as follows:

(5, 55000) and (8, 61600).

Dividing the change in the output by the change in the input, the slope m is given as follows:

m = (61600 - 55000)/(8 - 5)

m = 2200.

Hence:

P(t) = 2200t + b.

When x = 5, y = 55000, hence the intercept b is given as follows:

55000 = 2200(5) + b

b = 55000 - 2200(5)

b = 44000.

Hence the function is:

P(t) = 2200t + 44000.

2010 is 10 years after 2000, hence the estimate is given as follows:

Find the LCM of the denominators:

Answer: a) To make apple crumble for 16 people, Farid will need to double the ingredients as compared to serving 8 people. Hence, he will need:

700g * 2 = 1400g of apples

240g * 2 = 480g of sugar

180g * 2 = 360g of flour

So, Farid needs 360g of flour to make apple crumble for 16 people.

b) To make apple crumble for 2 people, Amal will need to use 1/8 of the ingredients as compared to serving 8 people. Hence, she will need:

700g / 8 = 87.5g of apples

240g / 8 = 30g of sugar

So, Amal needs 30g of sugar to make apple crumble for 2 people.

c) To make apple crumble for 6 people, Shahina will need to adjust the ingredients based on the apples she has available. To calculate the amount of sugar and flour required, she can use the ratio of sugar and flour to apples as follows:

Sugar: 700g / 8 = 87.5g per serving * 6 people = 525g

Flour: 700g / 8 = 87.5g per serving * 6 people = 525g

Since Shahina has plenty of the other ingredients, including butter, she can make apple crumble for 6 people with the amount of apples she has available. So, the answer is Yes, Shahina can make apple crumble for 6 people.

The area of a 7 by 10 grid would be 70 square units.

This is calculated by multiplying the length (7 units) by the width (10 units), resulting in 7 x 10 = 70.

The length of segment AB is determined as 13 units.

The distance between two points is the length of the line segment that connects the two points in a plane.

here, we have,

The length of segment AB is the distance between point A and point B, which is calculated as follows;

|AB| = √[(x₂ - x₁)² + (y₂ - y₁)²]

where;

x₁ is the x - component of point A

x₂ is the x - component of point B

y₁ is the y - component of point A

y₂ is the y- component of the point B

|AB| = √[(x₂ - x₁)² + (y₂ - y₁)²]

|AB| = √[(-5 - 7)² + (5 - 10)²]

|AB| = √[144+25]

|AB| = 13 units
