erma4kov [3.2K]

Answer: 374416

Step-by-step explanation:

Given : A test requires that you answer first Part A and then either Part B or Part C.

Part A consists of 4 true false questions, Part B consists of 6 multiple-choice questions with one correct answer out of five, and Part C consists of 5 multiple-choice questions with one correct answer out of six.

i.e. 2 ways to answer each question in Part A.

For 4 questions, Number of ways to answer Part A = $2^4$

5 ways to answer each question in Part B.

For 6 questions, Number of ways to answer Part B = $5^6$

6 ways to answer each question in Part C.

For 5 questions, Number of ways to answer Part C = $6^5$

Now, the number of ways to completed answer sheets are possible :_

$2^4\times5^6+2^4\times6^5\\\\=2^4(5^6+6^5)\\\\=16(15625+7776)\\\\=16(23401)=374416$

Hence, the number of ways to completed answer sheets are possible = 374416

Mikayla is a waitress who makes a guaranteed $50 per day in addition to tips of 20% of all her weekly customer receipts, t. She

notsponge [240]

Answer:

D. $f(t)=300+0.20t$

Step-by-step explanation:

We have been given that Mikayla is a waitress who makes a guaranteed $50 per day.

Since Miklaya works 6 days per week, so the guaranteed income for one week would be $\$50\times 6=\$300$

We are also told that she gets tips of 20% of all her weekly customer receipts, t. So amount earned from tips would be 20% of t, that is $\frac{20}{100}t=0.20t$ .

Total amount earned in one week would be guaranteed income for 1 week plus 20% of t:

$300+0.20t$

Therefore, our required function is $f(t)=300+0.20t$ and option D is the correct choice.

How much should you invest now at 7 1/4% simple annual interest in order to earn $190 interest in 4 months?

vlabodo [156]

Answer:

so principal amount is $7862.07

Step-by-step explanation:

Given data

rate = 7*1/4 % = 29/4 %

interest = $190

time = 4 months = 4/12 year

to find out

principal

solution

we know the simple interest formula i.e.

interest = ( principal × rate × time ) /100 ..................1

now put all value rate time and interest in equation 1 we get interest here

interest = ( principal × rate × time ) /100

190 = ( principal × 29/4 × 4/12 ) /100

principal = 190 × 12 ×100 / 29

principal = 7862.068966

so principal amount is $7862.07
