Answer: The vendor sold 9.5 scarves.

Step-by-step explanation:

I know that 10 x 10 is 100. HOWEVER, this only tells how many gloves were sold. To get how many scarves were sold: you need to:

100 + 8x = 176 or 10 x 10 + 8x = 176

176 - 100 = 76 or 10 x 10 = 100   176 - 100 = 76

both problems 76 divided by 8 = 9.5

Thus, my answer would be 9.5 scarves were sold (or if you round, about 10 scarves were sold).

Marilyn has 7/8 yard of ribbon. What is the maximum number of 1/16 yard long pieces Marilyn can cut from this ribbon
bogdanovich [222]

Marilyn can cut 14 equal pieces

<em><u>Solution:</u></em>

Given that, Marilyn has 7/8 yard of ribbon

To find: Maximum number of 1/16 yard long pieces Marilyn can cut from this ribbon

From given information,

\text{Total length of ribbon } = \frac{7}{8} \text{ yard }

\text{Length of 1 piece } = \frac{1}{16} \text{ yard }

Number of pieces that can be cut from total length of ribbon is found by dividing the total length of ribbon by length of 1 piece

Therefore,

\text{Number of pieces } = \frac{\text{Total length of ribbon}}{\text{Length of 1 piece }}

Substituting the values, we get

\text{Number of pieces } = \frac{\frac{7}{8}}{\frac{1}{16}}\\\\\text{Number of pieces } = \frac{7}{8} \times \frac{16}{1}\\\\\text{Number of pieces } = 14

Thus 14 pieces of ribbon can be cut

If f(x) = 2x + 3 for all values of x, what is the value of f(-3)?​
IrinaK [193]

Answer:

f(-3)= -3

Step-by-step explanation:

We are given the function:

f(x) = 2x+3

and asked to find f(-3). Essentially, we want to find f(x) when x is equal to -3.

Therefore, we can substitute -3 for each x in the function.

f(x)= 2x+3 at x= -3

f(-3)= 2(-3) +3

Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition and Subtraction

Multiply 2 and -3.

f(-3) = (2*-3) +3

f(-3)= (-6)+3

Add -6 and 3.

f(-3)= (-6+3)

f(-3)= -3

If f(x)= 2x+3, then<em> f(-3)= -3</em>

A town with a population of 5,000 grows 3% per year. Find the population at the end of 10 years
Sonbull [250]
6500 because if you take 3% of 5000 you get 150, so that’s 150 more people in the population per year. So you multiply 150 times 10 and you get 1500 and then you add your 5000 and get 6500.
