A bakery asks 75 customers to vote for a new bagel flavor. Onion flavor receives 33 votes. Cheddar flavor receives 42 votes. Use
m_a_m_a [10]

Using proportions, it is found that:

  • The fraction that shows the proportion of customers who voted for cheddar flavor is \frac{42}{75}
  • 56% of customers voted for cheddar flavor.

  • A proportion is the <u>number of desired outcomes divided by the number of total outcomes</u>.
  • A percentage is the <u>proportion multiplied by 100%</u>.

In this question, 42 out of 75 customers voted for the cheddar flavor, hence:

p = \frac{42}{75}

That is, the fraction that shows the proportion of customers who voted for cheddar flavor is \frac{42}{75}

The percentage is:

\frac{42}{75} \times 100\% = 56\%

56% of customers voted for cheddar flavor.

What is the value of x?
Ray Of Light [21]
The Pythagorean Theorem states that a^2+b^2=c^2
We already have:
A^2+6^2=117
All we need to do is find the missing A by subtract b from c.
117-36=81
Now the square root of 81, 9.
So, x is 9 cm.

Incomplete question. However, here is a similar question attached.

Solve 3x^2 + 17x - 6 = 0.

Based on the work shown to the left, which of these values are possible solutions of the equation? Check all of the boxes that apply

A X=-6

B X=6

C X=-1/3

D X=1/3

E X=0

Answer:

A and D

Step-by-step explanation:

Note that such question requires using completing the square method of solving equations. By using the values X= -6 and X= 1/3 we arrive at a solution.

Angie makes a spicy salsa by adding red pepper flakes to a chunky tomato mix in proportional amounts. For example she mixes 1/2
Nastasia [14]

Answer:

Please read the answer below.

Step-by-step explanation:

1. Let's represent the relationship between red pepper flakes, in teaspoons, to tomato mix, in cups in a table

Red pepper (teaspoons)   1/2    1    1 1/2   2  2 1/2   3  3 1/2   4  4 1/2   5      

Tomato mix (cups)              2     4       6     8    10     12   14     16   18    20

2. Let's represent the relationship between red pepper flakes, in teaspoons, to tomato mix, in cups writing a equation:

t = amount of tomato mix cups

r = amount of red pepper flakes teaspoons

As we can see in the table,

<u>t = 4r</u>
