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.

3(x+2)-2(×+1) i need help with this problem
zhuklara [117]

Question:

What is 3(x + 2) - 2(x + 1)?

Steps:

When you solve this type of equation always use the distributive property formula to solve this equation!

Formula: a(b + c) = ab + ac

So, what is 3(x + 2) ?

  • 3x + 6

Also, what is -2(x + 1)?

  • -2x - 2

Then, put it back into the equation for you to solve this problem.

So, this would be the new equation:

3x + 6 - 2x - 2

Then, what you want to do is put variables next to each other and the numbers next to each other so it will be easier to simplify:

3x - 2x + 6 - 2

Then, simplify:

x + 4 is the answer!

Since 3x - 2x = x and 6 - 2 = 4


Hope that helped!!

2. In a given country, records show that of the registered voters, 45% are Democrats, 35% are Republicans, and 20% are independe
Kitty [74]

Answer:

P(R) = 0.14

P(I) = 0.16

P(D) = 0.315

Step-by-step explanation:

Let Democrat = D

Republican = R

Independent = I

If 45% are Democrats, 35% are Republicans, and 20% are independents, then

Total registered voters = 100

 In an election, 70% of the Democrats, 40% of the Republicans, and 80% of the independents voted in favor of a parks and recreation bond proposal. That is,

D = 0.7 × 45 = 31.5

R = 0.4 × 35 = 14

I = 0.8 × 20 = 16

 If a registered voter chosen at random is found to have voted in favor of the bond, what is the probability that the voter is

a Republican:

P(R) = 14 /100 = 0.14

an Independent

P(I) = 16/100 = 0.16

a Democrat

P(D) = 31.5/100 = 0.315

IF SOMEONE COULD HELP WITH THIS IT WOULD BE MUCH APPRECIATED!
julsineya [31]

Answer:

48 Units

Step-by-step explanation:

Use the Pythagorean theorem to make two right triangles.

Ex= Base is cut in half to make two 9 unit bases

Then count the units from the half point.

Ex= 12 units long

Then use Pythagorean theorem to find one side of the 9-12 right triangle

Ex= 9^2+12^2=c^2

After finding that c=15 units, add all the sides back together

Ex= 18+15+15=48
