Which word begins with an open syllable?
silly
sister
sofa
softer

Answers

The word sofa begins with an open syllable.

Phonetics is the study of the sound of words/ speeches. This branch of linguistics deals with how words and letters sound and classifies them accordingly.

In phonetics, open and closed syllables refer to the specific nature of how the words end. This means that the words that end with a vowel are known as open syllables while the words that end with a consonant are known as closed syllables. Now, looking at the individual words given in the question, we can ascertain that the initial syllables of the words "silly, sister, softer" all ends in a consonant word. On the other hand, the word "sofa" begins with a vowel "o", thereby making it an open syllable.

The easiest way to detect an open and closed syllable is by identifying the position or use of the vowels and consonants in a syllable. This makes the word "sofa" an open syllable.

What is the Answer to 50 + 10 x 0 + 7 + 2

Answers

using pemdas (parentheses, exponent, multiplication, division, addition, and subtraction):

first, we multiply 10 x 0 because m is before a which equals 0.

then, add in the order of the equation, 50 + 0 + 7 + 2 = 59

Arithmetic involves carrying out addition, subtraction, division and multiplication on numbers and expressions. The result of [tex]50 + 10 \times 0 + 7 + 2[/tex] is [tex]59[/tex]

Given that:

[tex]50 + 10 \times 0 + 7 + 2[/tex]

To do this, we apply BODMAS.

First, we evaluate all multiplication operations

[tex]50 + 10 \times 0 + 7 + 2 = 50 + 0 + 7 + 2[/tex]

Then evaluate all addition operations

[tex]50 + 10 \times 0 + 7 + 2 = 59[/tex]

Hence, the result of [tex]50 + 10 \times 0 + 7 + 2[/tex] is [tex]59[/tex]

7. Fuji the woodworker sells cribs. His start-up
costs total $2000. Labor and material for
each crib cost $185. If the formula for his
Cost(C) based on (n) number of cribs is:
C=2000 + 185n , Tell what the rate of change
is and what it tells us about Fuji's expenses.

Answers

Answer:

The rate of change is 185.

It tells us that Fuji's expenses increase by $185 for each additional crib made.

Step-by-step explanation:

In a linear equation, the rate of change is the change in y over the change in x.

In this situation, that means how much the cost will change based on the amount of cribs that Fuji has to make.

Since labor and material costs for each crib cost $185, 185 is the rate of change.

For every additional crib that Fuji makes, the cost will increase by $185.

So, the rate of change is 185 and it tells us that Fuji's expenses increase by $185 for each additional crib made.

Answers

Answer:

7 DVDs

Step-by-step explanation:

Christine spent $29.50 in total, and $5 on the membership.

so the amount of money spent on DVDs is $29.50 - $5, or $24.50.

The number of DVDs she rent are $24.50 / $3.50 = 7 DVDs

Answer:

7 DVDs

Step-by-step explanation:

We can create an equation to found out how many DVDs she rents. Let d = number of DVDs she rents.

3.50d + 5 = 29.50

~Subtract 5 to both sides

3.50d = 24.50

~Divide 3.50 to both sides

d = 7
