Answer:

Step-by-step explanation:

d + q = 94.....d = 94 - q

0.10d + 0.25q = 19.30

0.10(94 - q) + 0.25q = 19.30

9.4 - 0.10q + 0.25q = 19.30

-0.10q + 0.25q = 19.30 - 9.40

0.15q = 9.90

q = 9.90/0.15

q = 66 <===== there are 66 quarters

d + q = 94

d + 66 = 94

d = 94 - 66

d = 28 <==== there are 28 dimes

Since a straight line is 180 degrees, if you subtract 180-48 you get 132. Divide this by 2 and get X= 66. Because all angle of a triangle add up to 180, subtract the 90 from the right angle and 66 from x from 180. 180-66-90= 24. This means z=24

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.
