Angela is competing in a dance competition. If dance move is done correctly, the dancer earns points. If a dance move is done incorrectly the dancer loses points. Angela currently has 200 points. Angela then loses 30 points and earns 70 points. Write and evaluate an expression to find Angela’s final score

20/8 = 2.5

multiply all the ingredients by 2.5

10 ml  * 2.5 = 25 ml of baking powder

70 *2.5 = 175 ml of butter

190 * 2.5 = 475 ml of sugar

420 * 2.5 = 1050 ml of flour

4.625 as a fraction in the simplest form can be written as 37/8.

Given is a decimal number 4.625.

Here the decimal point is 3 units to the left.

So any decimal number can be written as a fraction with powers of 10 as the denominator.

Here since the decimal point is 3 units to the left divide by 1000.

So,

4.625 = 4625 / 1000

Both 4625 and 1000 are multiples of 25.

So this can be written as  :

4625 / 1000 = 4625 ÷ 25/ 1000 ÷ 25

                    = 185 / 40

                    = 37/8

Final answer:

There will be 36 handshakes among the nine people at the party, as determined by the combination formula 9C2.

Explanation:

Calculating Handshakes

To determine the number of handshakes that occur when nine people shake hands with each other, we can use the concept of combinations. In a handshake situation, the order in which the handshakes occur does not matter; what matters is which two people are shaking hands. Therefore, we can use the formula for combinations without repetition, which is nCk = n! / (k!(n-k)!), where n is the total number of items, and k is the number of items to choose at a time.

In this case, there are 9 people (n=9) and the handshake involves 2 people at a time (k=2). So, the calculation would look like this:

9C2 = 9! / (2!(9-2)!) = 9! / (2!7!) = (9 × 8) / (2 × 1) = 36 handshakes

Therefore, there would be a total of 36 handshakes among nine people at the party.

Final answer:

The GCF of 55 and 88 is 11. Applying the distributive property, 55 + 88 is equal to 143.

Explanation:

The student is asking about the greatest common factor (GCF) and the distributive property of the expression 55 + 88.

To find the GCF, we need to break down the numbers 55 and 88 into their prime factors. The prime factorization of 55 is 5 × 11, and the prime factorization of 88 is 2² × 11. The GCF is the highest common factor between the two prime factorizations, which is 11.

The distributive property states that a × (b + c) = a × b + a × c. Applying this property to the expression 55 + 88, we get 11 × 5 + 11 × 8 = 55 + 88 = 143.

Final answer:

The GCF of 55 and 88 is 11. When we apply the distributive property to 55 and 88, the expression simplifies to 143.

Explanation:

To find the Greatest Common Factor (GCF) of 55 and 88, we can first list the factors of each number:

Factors of 55: 1, 5, 11, 55

Factors of 88: 1, 2, 4, 8, 11, 22, 44, 88

The GCF is the largest factor that both numbers have in common, which in this case is 11.

Now, let's apply the distributive property to the numbers 55 and 88:

55 + 88 = (5 * 11) + (8 * 11)

Using the distributive property, we can simplify this to:

55 + 88 = (5 + 8) * 11

Therefore, the expression 55 + 88 is equal to 13 * 11, which is 143.

Measure of ∠HNK is equals to 73°.

" Linear angles are formed when the sum of pairs of adjacent angles is equals to 180°."

According to the question,

Measure of ∠GNF = 60°

Measure of ∠MNL = 47°

As per the linear pair angles definition ,

∠GNF, ∠FNM,  ∠MNL forms linear pair angles .

Therefore,

∠GNF + ∠FNM + ∠MNL = 180°

Substitute the given values we get,

60° + ∠FNM + 47° = 180°

⇒ ∠FNM = 180° - 107

               = 73°

As given three lines intersect at 'N'

∠FNM and ∠HNK are vertically opposite angles and are congruent.

Therefore,

Measure of ∠HNK = 73°

Hence, measure of ∠HNK is equals to 73°.

Answer:

x=6-2y

Step-by-step explanation:

The correct answers are:

Distributive property; subtraction; addition property of equality.

Explanation:

To get from the first step to the second step, the terms inside parentheses have been multiplied by -2.  The property that allows us to multiply through parentheses, or distribute through parentheses, is the distributive property.

To get from the second step to the third step, the -6 and 4 have been subtracted; this means the reason for this is subtraction.

To get from the fourth step to the fifth step, 10 has been added to each side.  The addition property of equality allows us to do this.

Inequalities help us to compare two unequal expressions. The given inequality can be solved as shown below.

The slope of the line is the ratio of the rise to the run, or rise divided by the run. 9/2  is the slope of a line passing through the points (2, 5) and (0, −4)

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The given two points are (2, 5) and (0, −4)

The slope of line passing through two points (x1,y1) and (x2,y2) is

m=(y₂-y₁)/(x₂-x₁)

where m is the slope of line.

x₁=2,x₂=0, y₁=5,y₂=-4

Substitute the values of x₁, x₂, y₁ and y₂ in formula of slope

=-4-5/0-2

Minus plus minus we get plus, so add -4 and -5

=-9/-2

The minus on numerator and denominator will be cancelled.

=9/2

Hence slope of a line passing through the points (2, 5) and (0, −4) is 9/2.
