Answers

Answer:

22.5$

Step-by-step explanation:

So first we can insert 2.5 into the equation so that we get the right answer:

10+5(2.5)

We can now simplify by doing 5 times 2.5 which is 12.5

We then add 10 to 12.5 to get our answer; 22.5$

Last week Betsy made 80 on her quiz. This week she made 76. What is the percent of decrease in her score?

Answers

From the information given, she made an 80 the first week she took the quiz, then the next week she made a 76. Furthermore, we are asked to find the percent decrease.

Decrease means less. And less means subtraction in terms of Mathematics. So, hence, subtract 76 from 80 to find the percent decrease.

80 - 76 = 4

Now, just add the percentage behind the result.

Therefore, the percent decrease in Besty's score is 4%.

MODELING REAL LIFE: Faucet A
leaks at a rate of 21 liters per
day. Faucet B leaks at a rate
of 30 drips per minute.
Which faucet leaks at a
faster rate? (1 liter= 4000 drips)

Answers

Answer:

It would be Faucet A

Once we transfer liters to drips:

Faucet A= 84,000 drips

Faucet B= 30 drips

As you can tell, Faucet A is dripping way more than Faucet B.

Answers

Answer:

L = 1/2(P) - W

Step-by-step explanation:

Step 1: Flip the equation.

[tex]2L+2W=P[/tex]

Step 2: Subtract 2W from both sides.

[tex]2L + 2W - 2W = P - 2W[/tex] [tex]2L = P - 2W[/tex]

Step 3: Divide both sides by 2.

[tex]\frac{2L}{2} = \frac{P-2W}{2}[/tex] [tex]L = \frac{1}{2}P - W[/tex]

Therefore, the answer is [tex]L = \frac{1}{2}P - W[/tex]

Answer:

g(x) = 14x +7g(x) = 7x -18g(x) = -7x -16g(x) = 21x +17

Step-by-step explanation:

The transformations of interest here are ...

g(x) = b·f(x) . . . . vertical scaling by a factor of bg(x) = f(-x) . . . . . reflection across the y-axisg(x) = f(x -h) +k . . . translation h units right and k units up

1. The transformation parameters are given as b=2, (h, k) = (0, -3). Then we have ...

f1(x) = 2f(x) = 2(7x +5) = 14x +10 . . . . . vertical stretch by 2

g(x) = f1(x -0) -3 = 14(x -0) +10 -3

g(x) = 14x +7

2. (h, k) = (3, -2)

g(x) = f(x -3) -2 = 7(x -3) +5 -2 = 7x -21 +3

g(x) = 7x -18

3. The reflection gives us ...

f1(x) = f(-x) = 7(-x) +5 = -7x +5

Then the translation 3 left is (h, k) = (-3, 0).

g(x) = f1(x -(-3)) +0 = -7(x +3) +5 = -7x -21 +5

g(x) = -7x -16

4. The transformation parameters are b = 3 and (h, k) = (0, 2).

f1(x) = 3f(x) = 3(7x +5) = 21x +15 . . . . . . vertical stretch by 3

g(x) = f1(x) +2 = 21x +15 +2

g(x) = 21x +17

No you aren’t but your close. You are writing how much each pan makes instead of how many time you need it to make 30. A for example makes 15 muffins, so you take the 30 muffins you need and divide it by how many muffins you can make in one pan. So 30/15 would be 2 times she’d need the pan, that’s the answer for A. B makes 6 muffins, so 30/6=5 times she’d need the pan. Understand?
