Answers

20/8 = 2.5

multiply all the ingredients by 2.5

In 2008 election there was 28 blue states and 22 red states express the red and blue states as fractions in lowest terms of the total number of states and also as decimals

Answers

Let's start with the blue states. Out of 50 states, 28 of them were blue.
Therefore, the fraction would be 28/50. Let's reduce it.
28/50=14/25 --> these are the lowest terms for this fraction
Use a calculator to find the decimal solution --> 14/25= .56

Now, let's do the red states. Out of the 50 states, 22 of them were blue.
22/50=11/25 --> lowest terms
Use a calculator --> 11/25= .43

The state of South Carolina has 46 counties. Write 46 as a product of primes

Answers

Final answer:

The prime factorization of the number 46 is 2 times 23, with 2 and 23 being prime numbers.

Explanation:

To write the number 46 as a product of prime numbers, we need to perform prime factorization. Here is the step-by-step process:

First, find the smallest prime number that divides into 46, which is 2.Divide 46 by 2, which gives us 23.Since 23 is a prime number itself and cannot be divided further by any prime number other than 1 and itself, we stop here.

So, the prime factorization of 46 is 2 times 23. This can't be simplified any further as these are both prime numbers.

Mrs.D. gives 13 % of her salary to a charity. Last year she donated to the charity $6500.00. How much money did Mrs.D. earn last year?

Answers

Let x = Mrs. D's salary last year

13% = 13/100 = 0.13

6500 is 13 percent of Mrs. D's salary, so:

0.13(x) = 6500

0.13(x)/0.13 = 6500/0.13

x = 50,000

Mrs. D's salary last year was 50,000 dollars.

GCF and Distributive property of 55 + 88

Answers

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.

In the diagram to the right three lines intersect at n.The measure of < GNF is 60, and the measure of < MNL is 47. What is the measure of < HNK?

Answers

< GNL = 60
< MNL = 47

< MNL and < GNH are vertical angles and are equal
so < GNH = 47

< GNL + < GNH + < HNK = 180....these angles form a straight line...so when added, they equal 180

60 + 47 + < HNK = 180
107 + < HNK = 180
< HNK = 180 - 107
< HNK = 73 <====




Measure of ∠HNK is equals to 73°.

What are linear pair angles?

" 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°.

4=4 multiply (8/8) = 32/8
so 4.625 = 32/8 add 5/8 equal 37/8

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

Nine people come to a party and shake hands with each other. If each person shakes the hand of every other​ person, how many handshakes​ occur?

Answers

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.

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
